i can delete only 1 record. i want 2 or more data to delete if the checkbox is check. thanks

well, you have to be creative with loops but I will tell you the primary ingredient for however you are going to do it and that is the ability to have multiple checkboxes submit into a single array. for example:

<input type="checkbox" name="delete[]" value="1" /><br />
<input type="checkbox" name="delete[]" value="2" /><br />
<input type="checkbox" name="delete[]" value="3" /><br />
<input type="checkbox" name="delete[]" value="4" /><br />
<input type="checkbox" name="delete[]" value="5" /><br />

each selected checkbox will be added to the array $_POST so you can make a loop with $_POST like so:

foreach($_POST['delete'] as $deleteID)
{
      //you are now iterating through all of the selected checkboxes and $deleteID contains the value for each checkbox
}

so ill create many checkbox?

no need to create you have to use for loop for this.

ok thanks :)
