I'm totally new to DirectPHP, that I'm trying to use in my Joomla 1.5 website (www.cascinesanpietro.it).
Website it's just starting, still with lot of example joomla contents.
When I try the code:
<?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;?>

I get the error message:
Parse error: syntax error, unexpected T_GLOBAL in /web/htdocs/www.cascinesanpietro.it/home/plugins/content/DirectPHP.php(49) : eval()'d code on line 2


The plugin is enabled, and its order is 2 (not 0).

It seems to work, a little, when I use your example code:

Now is: <?php echo date('Y-m-d H: i: s');?>
(added space after ":" to avoid emoticons)

but I had to add a question mark "?" after "<", before keyword "php". WHy didn't you put it? I'm asking it because I'm always afraid to lose some bit of information.
Thank you for your valuable work.
Greetings from Italy

Hi Salvatore,

Those are typos. DirectPHP uses the standard php syntax i.e. a question mark "?" after "<", before keyword "php. I've fixed all those typos in:

http://www.kksou.com/php-gtk2/Joomla/DirectPHP-plugin.php

I went to your site: www.cascinesanpietro.it. Those error messages are typed in by you. Can you please put back your PHP code and let me see the exact thing as reflected by DirectPHP.

Hi Kksou, thank you so much about your FLASH answer!
I cleaned the situation. Now there is only the first comment line, and everything else is php code and system error message.
Thank you again!
Salvatore

Hi Salvatore,

Have relooked at your site. Need a bit more clues:

1. May I know when did you download the DirectPHP? Recently? Or sometime ago?

2. Are you using PHP4 or PHP5?

3. Can you copy and paste again here the code you have used that produce the error.

Regards,
/kksou

Hi Salvatore,

Please try one more thing. I assume you're using the latest version of DirectPHP:

1. Go to the folder plugins/content

2. Edit the file "DirectPHP.php" in your favorite editor.

3. Goto line 46 and add the line

Code:

echo "phpcode2 = ".htmlentities($phpcode2)."<br>";

so that it looks like:

Code:

$output .= $matches[1]; $phpcode = $matches[2]; $phpcode2 = $this->fix_str2($phpcode); echo "phpcode2 = ".htmlentities($phpcode2)."<br>"; // add this line global $errmsg; if ($this->check_php($phpcode)) {

4. Now reload the page again. You should see the "real" PHP code that are being evaluated by DirectPHP. It will allow us to see what's really happening "behind the scene".

this is the code:

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

<?php
function f1() {

$b = f1($a);
?>

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



Hope this can help you.
Thank you.

Hi Salvatore,

Thanks for the detailed info.

You're using PHP4!

You must have downloaded the version of DirectPHP quite some time ago.

The previous version of DirectPHP doesn't work with PHP4. I've updated the code quite some time ago so that it works with PHP4.

Please download the latest version of DirectPHP from
http://www.kksou.com/php-gtk2/Joomla/DirectPHP-plugin.php
and see if it works on your site.

Regards,
/kksou

Sorry about it, KKsou, I forgot to answer this specific quesiton. But I downloaded DirectPHP just today!
File name is DirectPHP_v1.54.zip.
Readme file states:

Version: 1.0
I'm afraid that we still didn't pinpoint the reason of the error... :-)
Salvo

Hi Salvatore,

In that case, please add the line:

Code:

echo "phpcode2 = ".htmlentities($phpcode2)."<br>";

as mentioned above.

It will allow us to see the actual PHP code that is being processed.

Regards,

/kksou

Ok Kksou, I did it and this is the result:

phpcode2 = global $a; $a = 10;
phpcode2 = echo $a;
phpcode2 = function f1() { Â Â Â global $a; Â Â Â return $a*2; } $b = f1($a);
phpcode2 = echo $b;

as you can see looking at the website.
This "Â Â Â" sounds not very nice. Something about char generator?
