Checking to see if dynamic checkboxes are set

vocoder

I have a PHP script which generates dynamic checkboxes for example lets say the name of the checkbox is

weeknumber_dayofweek_checkbox_storynumber

so maybe i have 5 stories on monday and 2 stories on tuesday

so then it generates 7 checkboxes with names

36_monday_checkbox_1
36_monday_checkbox_2
36_monday_checkbox_3
36_monday_checkbox_4
36_monday_checkbox_5
36_tuesday_checkbox_1
36_tuesday_checkbox_2

so then i have another php file and i need to check to see if any of those are checked. I was thinking of using isset, but I'm not sure how to use it with this setup. Basically what I plan to do is if the checkbox is set, delete that story. Any ideas?

Depends on what version of php you are using this will only work with php version > 4.1. (and also assumes that the form's method is set to post rather than get)

foreach ($_POST as $key => $value)
{
// code to execute deletion of news item goes here
}

Only information for checkboxes that are ticked will be returned in the $_POST array, No information will be available in the array for checkboxes that are not ticked.

the values that you describe in your post will then be available in the $key variable for each checkbox that is checked

I tried this

foreach ($_POST as $key => $value)
{
echo $key;
}

and it prints nothing....i am using the latest version of php and my form method is set to post, and i have register_globals set to on. any idea what i'm doing wrong?
