Problem This is in response to Manar's post titled "select a week from GtkCalendar".
She would like to be able to select a week from GtkCalendar as shown below.
Solution
- We use almost entirely the same code from How to let user enter date with a popup calendar - Part 2?
- We then use the php function
strtotime to help us calculate the date of the start of week and end of week.
- Note that in this example, the week starts from Monday. If you prefer the week to start from Sunday, you can easily modify the code.
