[RESOLVED] Deleting Private Messages...

[Jaquio]

Alright.. I am making a website, an I made a custom private messaging system, thing is.. I cannot seem to figure out how to delete multiple PMs at once.. Could someone explain to me how this is done? (I am using a check-box to select the wanted pms that are going to be deleted).

Up to you.

Each check box would be one POST/GET parameter (POST would be the proper method) so you'd need to loop through POST paremeters I suppose.

foreach($_POST as $postvar => $postval) {
  // some way of identifying it as a checkbox var
  if (
    substring($postvar, 0, 1) == 'pm' &&
    (bool)$postval
  ) {
    // delete the PM
    // possibly, the ID would be the rest of the checkbox name?
    $pm_id = substring($postvar, 2, strlen($postvar));
  }
} 

That's vague, but you get the idea?

$_POST = the word 'Array'.. When I try to "array($_POST)" it still returns array.. Any idea as to how I can get this working?


Edit:

Sorry, I didn't read your post right. It works correctly, thanks.

No problems, glad you sorted it

I usually construct the list as follows in html. Assuming each PM has an ID:

PM 1  <input type="checkbox" name="delete[]" value="1" />
PM 2 <input type="checkbox" name="delete[]" value="2" />
PM 3  <input type="checkbox" name="delete[]" value="3" />
PM 4 <input type="checkbox" name="delete[]" value="4" />

Beucase you called it delete[], PHP will automatically construct an array containing the values of the numbers selected:

if(isset($_POST['delete']) && is_array($_POST['delete'])) {
    foreach($_POST['delete'] as $pmId) {
        $pmId = (int) $pmId; // samitise appropriatly
        // delete PM
    }
}

Sweet, that's way better than my method
