checkboxes and php post

I want to add some check boxes next to my pages in the administration area which lists all the pages i have in the system. When checked and posted these pages can then be deleted. But how can i deal with multiple checks if i name the checkboxes the same name? For example:

<input type="checkbox" name="check" value="{$Page_ID}">check1
<input type="checkbox" name="check" value="{$Page_ID}">check2
<input type="checkbox" name="check" value="{$Page_ID}">check3
<input type="checkbox" name="check" value="{$Page_ID}">check4

if i post and pick up $_POST['check']

if there a way i can extract the page_IDs in a loop and delete from the database. Perhaps in a while loop or something:

<?php
while($_POST['checkbox']){
     mysql_query(\"delete from db where Page_ID={$_POST['checkbox']}\",$con);
}
?>

OR something like this?

Sure can! Use an array for the names. They will all have to be different. The value will all be 1 (which will evaluate to "true" when we check if they are checked). The array indexes do not have to be in numerical order or not even numbers, it can be something like check['something'].

HTML Form:

<input type="checkbox" name="check[1]" value="1">check1
<input type="checkbox" name="check[2]" value="1">check2
<input type="checkbox" name="check[3]" value="1">check3
<input type="checkbox" name="check[4]" value="1">check4

In the PHP loop, $field is the index of the array, and $value is 1 if checked, and nothing if not checked.

PHP Loop:

<?php
   foreach ($_POST['check'] as $field => $value)
   {
      if ($value)
      {
         /* the checkbox was checked */
         
         /* TODO: code to delete stuff */
      }
   }
?>

Hope this helps!
