How to add a submit button in an HTML table?

Question

I need to call the gh_cart_prove when the BUTTON is clicked.

function gh_view_categories(){
  $a='<table>';
  $a.='<tr>';
  $a.='<td><strong>'.'Categoria:'.'</strong></td>';
  $a.='<td><strong>'.'Soglia minima:'.'</strong></td>';
  $a.='<td><strong>'.'Tot attuale:'.'</strong></td>';
  $a.='<td><strong>'.'Crea ordine'.'</strong></td>';
  $a.='</tr>';
  $query = db_select('uc_product_classes', 'u')
    ->fields('u', array('name','soglia', 'totattuale'));
  $result = $query->execute();
  while ($record = $result->fetchAssoc()) {
    $idUser=gh_get_user_id($record['name']);
    $a.='<tr>';
    $a.='<td>'.$record['name'].'</td>';
    $a.='<td>'.$record['soglia'].'</td>';
    $a.='<td>'.$record['totattuale'].'</td>';
    $a.='<td>'.'<button onClick="gh_cart_prove($idUser)">BUTTON</button>'.'</td>';
    $a.='</tr>';

  }

  $a.='</table>';

  return ($a);
}

The button appear but it not works. the function is correctly declared. How can I resolve this problem?

Answer 1

Assign an id to the button and use Jquery, set the $idUser in a data attribute example :

 <button id="buddon-id" data-user="<?php echo $idUser;?>" >button</button>
    <script>
    $("#button-id").on("click", function(e){
       userid = $(this).attr("data-user");
    };
    </script>
