Fetch Box Arrays in PHP

OK, I'm trying to get the loop of each array after they are selected ... add 'language' remove 'language' does not work. The problem is sending. I got stuck on how to actually get each rectangle to select through a PHP array.

Here is what I have:

You should use foreach as

 foreach ($_POST['langs'] as $value) { echo "Langs $i: " . $value; $i++; }

See here what foreach can do.

Correct line 23.

For some reason you are returning a name attribute.

OLD

 // manipulate the name/id values of the input inside the new element newElem.children(':first').attr('id', 'name' + newNum).attr('name', 'name' + newNum);

Fixed

 // manipulate the name/id values of the input inside the new element newElem.children(':first').attr('id', 'name' + newNum);

try it

 <?php if (isset($_POST['submit'])) { $i = 0; foreach ($_POST['langs'] as $value) { echo "Langs $i: " . $value; $i++; } } ?>
