[RESOLVED] Am I registering form checkboxes incorrectly?

[schwim]

Hi there folks!

I need to utilize a js "check/uncheck all" deal in my form and the only code examples I can find utilize the checkbox name, so the code checks and unchecks all the checkboxes with name=foo.

Unfortunately, I don't know how to handle checkboxes with the same name in my php. I've always done it via

<input type='checkbox' name='checkbox1' value='' />
<input type='checkbox' name='checkbox2' value='' />

then on the processing end of things:

if(ISSET($_POST['checkbox1'])){
    // Do the first checkbox thing.
}
if(ISSET($_POST['checkbox2'])){
    // Do the second checkbox thing.
}

I don't know how to handle two checkboxes with the same name on the processing end and I can't find a js example that will check across different names.

Could someone help me figure out how this is handled?

Thanks for your time!

Use:

<input type="checkbox" name="checkbox[]" value="1" />
<input type="checkbox" name="checkbox[]" value="2" />

Then it becomes an array in php, and you can do array things with it:

if( isset($_POST['checkbox']) ) {
   // Loop over them
   foreach($_POST['checkbox'] as $cbValue ) {
      echo "You checked $cbValue<br>";
   }

   // Check if they exist
   if( in_array(1, $_POST['checkbox']) ) {
      // do checkbox one thing
   }
   if( in_array(2, $_POST['checkbox']) ) {
      // do checkbox two thing
   }
}
