I would add another input, with type hidden to hold the total number of entries. I would have each name, telephone and id inputs have different ids by adding an index number for each, something like:

<?php 
$index = 0
foreach ($data['ACTION_DATA']['messages'] as $msg) { ?>
<form>
  <table>
   <tr><td>Name:</td><td id="name<?php echo $index;?>"><?php echo $msg['name']; ?> </td></tr>
   ... same for the others ...
   <?php // increment index 
    $index++;
    ?>
   ....

And then use a for loop (you can get the total number of entries form the hidden input field) to browse through all the values.

If you want to only view one of them, send the index number as a parameter to the show_popup() method.

can you use array.count function?

$total_tables = count($data['ACTION_DATA']['messages']);
