DirectPHP plugin

Written by kksou

Monday, 24 March 2008

This plugin allows direct embedding of PHP commands right inside Joomla content page for dynamic contents.

Available for both Joomla 1.0.x and native 1.5.x!

Latest version:
Updated: Apr 6, 2008
DirectPHP for Joomla 1.0.x: DirectPHP_v1.02
DirectPHP for Joomla 1.5.x: DirectPHP_v1.52
Note: if you downloaded a copy before Mar 28, please download this latest update. Please refer to the Version History for key changes.

Key Features

Include PHP commands right inside your Jommla content page using the standard php construct:

<php php_commands... ?>

Freely intermix static contents with php commands:

Now is: <php echo date('Y-m-d H:i:s');?>

Leverage on all your PHP libraries right inside the content page:

<php 
require_once('fullpath/your_lib.php');
your_php_func();
?>

You can edit the php code right inside the default TinyMCE WYSIWYG Editor!

Ability to block potentially "risky" commands, e.g. system, fopen, unlink, rmdir, etc. You can add and edit this list of commands-to-block yourself.

Background

I've recently redesigned this website using Joomla. As you can see, there are more than 450 PHP-GTK sample codes. It's just too much a hassle to include each sample code into every article. Isn't it nice if I could do a simple

echo "<pre>".htmlentities('filename.php')."</pre>";

to automatically include the respective sample code?

I've tried two other plugins: Jumi and RunPHP .

Jumi allows you to call or include another .php file. However, it doesn't allow you to add php commands right inside the content. What this means is that if you want to display a sample code, say example1.php, you need to create an intermediate .php file. In that intermediate php file, you then load and display the sample code with echo "<pre>".htmlentities('filename.php')."</pre>". These intermediate files accumulate very fast and is becoming a bit cumbersome.

RunPHP allows you to embed php commands right inside the content page. However, using it is a bit troublesome. You need to use, for example, JCE Editor with Show HTML view. You cannot use the default TinyMCE WYSIWYG Editor.

So I decided to develop my own plugin, and the result is this plugin DirectPHP.

How to install (Joomla 1.0.x)

Download the plugin and unzip it into a folder.
From the Installers menu, select mambots. In the field "Install directory", enter the folder location (where you unzipped the file) and click Install.
From the Mambots menu, select Site Mambots.
Make sure the plugin "DirectPHP" is published. If you see a cross in the Published column, just click on it. It will turn into a green tick.
To try if it works, go to Content Manager, and copy the following text into any static content page:

Current date and time is: <?php echo date('Y-m-d H:i:s');?>

Now load that content page. You should see the current date and time displayed.

To customize the block list (Joomla 1.0.x)

From the Mambots menu, select Site Mambots and then click on DirectPHP.
On the right-hand side, you will see the Plugin Parameters "PHP commands to block".
Edit this list and click Save.

How to install (Joomla 1.5.x)

Download the plugin and unzip it into a folder.
From the Extensions menu, select Install/Uninstall. In the field "Install directory", enter the folder location (where you unzipped the file) and click Install.
From the Extensions menu, select Plugin Manager.
Enable the plugin (DirectPHP) - make sure there is a green tick in the Enabled column.
To try if it works, go to "Content - Article Manager", and copy the following text into any static content page:

Current date and time is: <?php echo date('Y-m-d H:i:s');?>

Now load that content page. You should see the current date and time displayed.

To customize the block list (Joomla 1.5.x)

From the Extensions menu, select Plugin Manager, and click on DirectPHP.
On the right-hand side, you will see the Plugin Parameters "PHP commands to block".
Edit this list and click Save.

Examples

Here are some examples:

You can display the current date and time with:

 Now is: <?php echo date('l j D, Y H:i:s');?>

You can use for or foreach loop:

<?php
for ($i=0; $i<10; ++$i) {
    echo "$i: ".$i*$i,"<br>"; 
} 
?>

You can include your own PHP library and call the functions within that library:

<?php
require_once('/fullpath/your_php_library.php');
display_image('image123.jpg');
?>

You can sprinkle as many PHP statements you want within your content page. Note that these PHP statements will be processed in sequential order, and it respects all scoping of variables. So if you have set a variable earlier, you can use it in your PHP statements later.

<?php global $a;
$a = 10;?>
This is a test. variable $a = <?php echo $a;?>

<?php
function f1() {
    global $a;
    return $a*2;
}
$b = f1($a);
?>

You can access variable $a from within the function with global.
variable $b = <?php echo $b;?>

You can add any HTML statements through PHP:

<?php
echo "<table border=4$gt;";
echo "<tr><td>a11</td><td>a12</td></tr>";
echo "<tr><td>a11</td><td>a12</td></tr>";
echo "</table>";
?>

You can easily serve different contents for registered and non-registered members:

<?php
global $my;
if ($my->id==0) {
    // non-registered members
    print "Please register or login.";
} else {
    // registered members
    print "Contents for registered members.";
}
?>

Important Note: Blocking of PHP commands

By default, I've blocked some of the potentially "risky" commands, e.g. system, fopen, unlink, rmdir, etc.

You can view the entire list of PHP commands that are blocked in the plugin's property page. In there, you can also add, edit or delete this list of commands to suit your needs.

If you need to use any of these commands (e.g. mkdir) from within the content page, put them in one of the library files on your server, do a include() and then call that function. This is a much safer method.

If you insist, you may choose to turn off the blocking in the property page. However, I would strongly advise that you do so only if you're the only one maintaining your Joomla site. If you're opening up the adding and editing of content pages to the public, DO NOT turn off the blocking. It's too dangerous.

I would kill for this to work - but everytime I save it, then re-edit the content item, the php has disappeared. I'm using fck2 for an editor...

Hi Rod,

I don't use fck2. The plugin has been tested on the default TinyMCE WYSIWYG Editor.

But I'll install fck2 and test it out. Will get back to you as soon as I find out where's the problem.

using DirectPHP with JCK (was joomlafck2)
Hi Rod,

I supposed you're referring to JCK. The website said it was formerly called was joomlafck2.

I installed the editor. True enough. Entering and saving the code was ok. But when you tried to reload the content, the php code "disappeared".

I probed around and found a couple of things:
1) The code is still there in the mysql db. If you go straight into jos_content, you can see the code there.

2) Interestingly, if you do a view source, the code is also there! It's just not shown.

This leads me to realize that the code was being parsed by one of its javascript functions. That's why you can see it in view source, but the code is not displayed.

I believe the function is contained in the file:
mambots/editors/joomlafck2/editor/js/fckeditorcode_gecko.js

However, the author has "encrypted", or obfuscated, the code. So there's no easy way to change the code. I would suggest you contact the author to see if he's willing to add one more parameter so that user's can choose whether to view or not view the PHP codes.

As a "quick fix", you can actually comment out the code that make the PHP code disappear.

Open up the file: mambots/editors/joomlafck2.php. Scroll to the bottom. You will see the following statements:

<pre>
return <<<EOD
<textarea name="$hiddenField" id="$hiddenField" cols="$col" rows="$row" style="width:{$WidthCSS}; height:{$HeightCSS};">$content</textarea>

<script type="text/javascript">

/*

var oFCKeditor = new FCKeditor('$hiddenField');

oFCKeditor.BasePath = '$mosConfig_live_site/mambots/editors/joomlafck2/' ;
oFCKeditor.Width = '$wwidth' ;
oFCKeditor.Height = '$hheight' ;
oFCKeditor.ToolbarSet = '$toolbar' ;

oFCKeditor.Config['EditorAreaCSS'] = '$mosConfig_live_site/$content_css';
oFCKeditor.Config['StylesXmlPath']= '$mosConfig_live_site/mambots/editors/joomlafck2styles.xml.php?css_filename=$content_css' ;
oFCKeditor.Config['CustomConfigurationsPath'] = '$mosConfig_live_site/mambots/editors/joomlafck2.js.php' ;

oFCKeditor.ReplaceTextarea() ;

function InsertHTML(field, value) {
// Get the editor instance that we want to interact with.
var oEditor = FCKeditorAPI.GetInstance(field) ;

// Check the active editing mode.
if ( oEditor.EditMode == FCK_EDITMODE_WYSIWYG )
{
// Insert the desired HTML.
oEditor.InsertHtml( value ) ;
}
else
alert( 'Please switch to WYSIWYG mode.' ) ;
}
*/
</script>
<br />
<p>$buttons</p>
EOD;')
</pre>

Comment out the entire javascript code as shown above with /*...*/.

Try the editor again. You will be able to see all your PHP codes right there!

But of course, there's some problem with this approach. You will find that your editor has now become a pure HTML editor. If you need a line break, you have to manually enter a <br> or <p>.

So I guess the best is still for you to contact the author of JCK for help.

Having a slideshow module in main page
hmmm just want to know if this is possible for putting a slideshow module in the front main page mosbody easy?

should be like using {loadmodule mod_fpslideshow} for having that in a content article page easy. Is this possible ?
kksou
March 27, 2008 8:52am

Yes. You can actually easily create a module or component using this plugin.

If you're using Joomla 1.0.x, go to Module Manager, click New, then scroll all the way down to the bottom. In the custom output, you can add any PHP code here. It will be processed by the DirectPHP plugin.

So if you have written some PHP/javascript library that presents a slideshow of images, just create a module as described above and publish it in one of the module position in the front main page.

As for Joomla 1.5.x, the HTML module (was Custom module in 1.0.x) is no longer processed by the content plugins. The solution is to install a module called "CustomContent" by Ian MacLennan first. Once you've installed this module, you can publish any article in any module position. In that article, you can place any PHP code there, which will be processed by the DirectPHP plugin.

I will give more details and examples of creating modules and components using the DirectPHP plugin in the next one or two days.

Hi Rod,

I spent a bit more time with JCK and found a solution which seems to work.

Edit the file: mambots/editors/joomlafck2.php. Look for the function "function botEditorArea()". You will see the following 5 lines:

<pre>
$content = str_replace("<", "", $content);
$content = str_replace("&", "&", $content);
$content = str_replace(" ", " ", $content);
$content = str_replace(""", "\"", $content);
</pre>

Comment out this 5 lines altogether.

<pre>
/*$content = str_replace("<", "", $content);
$content = str_replace("&", "&", $content);
$content = str_replace(" ", " ", $content);
$content = str_replace(""", "\"", $content);*/
</pre>

Now edit an article and type in some fresh php commands (don't use the old one that you've typed before) and save it. Reload it. You should be able to see the php commands back in the editor.

I tried quite a few sample codes and they all seem to work.

Do give it a try. Hope it works on your machine too!

Small JoomlaFCK Editor problem
This is a very nice plugin, but I've run into a problem similar to Rod's. I'm using the JoomlaFCK editor (available from www.joomlafckeditor.com) with Joomla 1.5 and when editing an article that includes PHP it replaces some essential characters for the plugin to work. I tried looking in the editor's php file (plugins/editors/fckeditor.php) but couldn't find any lines similar to the ones you mention above.
Can you please take a look?

March 28, 2008 10:31am

Hi JoyMonkey,

From the filename you mentioned, looks like you're using JoomlaFCK v1. The one Rod used is v2.

Let me look around to see if ver 1 is still available for download. Will try it out and get back to you if there's any possible solution.

Regards,
/kksou
JoyMonkey
March 28, 2008 10:41am

No, it's not v1, it's a new branch of JoomlaFCK (it's a little confusing, I know). This is a new editor, but appears to be very popular.
Here is a direct link to the editor I'm using:

March 28, 2008 10:41am

Hi Ssnobben,

"What I mean is to publish it to mainpage mainbody."

Sorry I misunderstood your question earlier.

Yes, it's possible. You can actually "insert" a module into a content page. But this is a Joomla "feature" and you do not really need the DirectPHP plugin to enable this.

Doing this on Joola 1.0 and Joola 1.5 is slightly different. Give me about one day. Will post the solution in the tutorial section near the top of this page.

strip php for rss
Excellent plugin

Is there anyway to auto switch off the rss feed for any article that uses direct php - or strip the php out - at the moment the actual code shows in the feed.
Greivin Britton
March 28, 2008 5:46pm
I can't get this to work
When i do the test, only appear the text just like i put it. The plugin is enable and i'm set TinyMCE by default and i have joomla 1.5, could you please help with this...
kksou
March 29, 2008 1:15am

Hi Greivin,

If you're sure the plugin is enabled, then

1) First let's try this one more time:
now = <?php echo date('Y-m-d');?>
Please enter everything in one line (or just copy and paste into the editor). Reload the page. Did you see the php code or the time? Or did you see any error message?

2) If it still doesn't work, then may I know if yours is a fresh install of Joomla 1.5? Have you installed any other plugins? I know some plugins such as jReviews removes all modifications by other plugins. They simply load the original content straight from mysql db and rewrites the contents. So DirectPHP will not work if you have such a plugin installed.

3) As a test, you might want to try installing a fresh Joomla 1.5 into another location (it takes only about 5 minutes). Then install DirectPHP and see if it works. If it does work, then you know the problem is with one of the plugins that you have installed in your original Joomla.

Hope this helps...

Hi Gp44,

Which rss generator are you using? Are you using the rss feed that comes with standard Joomla installation? If yes, I could modify that to suit your need. (But please let me know which version of Joomla are you using - J1.0.13, J1.0.15 or J1.5?)

Hi JoyMonkey,

I tried all 3 versions of JoomlaFCK from
http://www.joomlafckeditor.com/index.php?option=com_content&view=category
&layout=blog&id=34&Itemid=61

All 3 versions (v2.5.1, v2.5.1.1 and v2.5.1.1b) seem to work fine. Switching between standard view and code view works fine too.

1. May I know if you're using any of these 3 versions, or an earlier version?

2. If you're using an earlier version, would you want to try the latest version and see if it works on your machine?

3. Also, may I know if the plugin is not working at all? Or only some of the php statements are not working? If it's only some, could you please show me some of these php codes that don't work? (need to know which of the characters get converted by the editor)

4. Lastly, does the simple statement:
now = <?php echo date('Y-m-d');?>
work on your machine? When you save the above statement and reload it in the editor, what did you see? Just 'now =' or any other text?

Re: problems with JoomlaFCK
1. I'm running the latest version (v2.5.1.1b).
2. I removed JoomlaFCK and re-installed it to make sure I'm using that version.
3. I've only tried one piece of php (your example #6).
4. Trying it now...
Inserting the line "now = " into an article using JoomlaFCK's 'Source' button works fine.
However, when I try to edit that article it removes the php code entirely, leaving it as "now ="

Hi JoyMonkey,

Thanks for the detailed description of what you've tried. Guess I know what's happening.

I followed what you did. Enter the php code in source mode. And then switch back to the editor mode. Yes, the codes are gone.

In JoomlaFCK, you have to enter those PHP code right in the editor mode (i.e. not the source mode). Try it. Just type <?php echo date('Y-m-d');?> direct into the editor and save it. It should work.

Please try one more time. Enter the following into editor all in one line:
Current date is: <?php echo date('Y-m-d');?>

If it still doesn't work, then one possible reason could be that you have other plugins installed that do not follow the standard rules. I know some plugins do that by overwriting whatever modifications that have been done by other plugins.

As a test, you might want to try installing a fresh of Joomla into another location (it takes only about 5 minutes). Then install DirectPHP and see if it works. If it does work, then you know the problem is with one of the plugins that you have installed in your original Joomla.

I installed directphp to a fresh joomla 1.5 install (using the installer and uploading the zip file, not unzipping and uploading as you described) and I am using the tinymce editor that is the default.

Unfortunately, whenever I enter the "<" character before php, it gets changed to "<" in the html (as does ">" get changed to something else. But when I go into the html and change it back to a "<" and ">" the whole php line i have entered simply disappears after saving - as in it is not there when I look back in the html for it.

Do you know the solution to my problem? I really hope to use your plugin!

April 22, 2008 7:27pm

Hi Tim ,

Yes, tinymce editor will change those < and > to some other characters. (In fact, it will change many other characters such as ' and ".)

But don't worry. My plugin will change all these back. So just go ahead and type those PHP commands in the tinymce editor. It should work just like that.

Note that if you change those htmlentities back to say '<' and '>' by directly editing the content in mysql, you will find that all your PHP commands will disappear. This is because the tinymce editor refuses to show any tags in the editor, even though all your codes are still there.

Alternatively, you might want to try installing other editors (one good one is JoomlaFCK) that allows you to easily switch between WYSIWYG mode and Source Code mode.

Thanks for your answer - it helped me narrow down what was happening.

I am working with a fresh joomla 1.5.2 install, but I did import the database from a an existing 1.0.13 site - so i guess that might not qualify as totally fresh.

Once I actually typed in the code (instead of relying upon elements of whatever was already there) things took.

It also helped greatly when I actually included the question mark in the opening php tag. Yes, I'm a php noob i guess.

Your plugin is awesome and it's so great it is 1.5 native. If you haven't already put it up on the joomla extension site, you really should. There are lots who will enjoy using it.

Problems with JCE editor
Hi Kksou, I'm using JCE Editor and installed DirectPHP plugin, pasted PHP your exemple code:
now =
but nothing happens. It's possible this plugin work together with JCE Editor?
kksou
April 23, 2008 7:00pm

Hi Filipe,

1) First double-check that the plugin is published.

2) Next go to Site - Global Configuration, and set Default WYSIWYG Editor to "No WYSIWYG Editor". Now enter the following into editor all in one line:
```
Current date is: <?php echo date('Y-m-d');?>
```
Reload the page. Did you see the date and time? If yes, it means DirectPHP is running ok. We can then know that the problem is with the JCE Editor.

3) I will try out the JCE Editor and see if I can find a fix.

Regards,
/kksou
kksou
May 02, 2008 3:43am

Hi Filipe,

I've installed the JCE Editor and tried it with DirectPHP. Yes, it does work.

One possible reason it didn't work on your system might be that: In JCE Editor, I see there's one [show/hide] link that let's you see the underlying HTML tags associated with the intro and fulltext.

I'll call the default view (the one with all the toolbars) the WYSIWYG mode, and the other view (with all the toolbars hidden) the source mode.

I believe you have entered the PHP commands in the source mode (the view without any of the toolbars). When you do this, when you switch back to the WYSIWYG mode, you will find that all your PHP commands are gone!

The "trick" is: you have to enter the PHP codes in the WYSIWYG mode.

Please give it a try one more time. Just copy and paste this line into the editor in the WYSIWYG mode:
```
Current date is: <?php echo date('Y-m-d');?>
```
Save and reload the page. The current date should be displayed.

$REMOTE_ADDR
Hi kksou,

First let me thank you for this great plugin.

Almost everything I tried so far did work; maybe you can help
me with the part that didn't?

I wish to display the Users IP-Adress on my page (great for supporting
via remote connection) with following code:

Your IP:

Unfortunately nothing seems to happen.

Can you bring in some light?

Thanks in advance

Another try
Thanks for getting back - it seems like the code was parsed... (with the same result as I get on my own page)
<?php echo "$REMOTE_ADDR";?>

Hi Markus,

Try this...

<?php echo "ip = ".$_SERVER['REMOTE_ADDR'];?>

Thanks!
(just gained 1 Star ;-) )
Guess I was too lazy in using the short form...

Works flawlessly!

Thanks,
