Question

I want to presist (=keep values if error on form) my values from a dropdown menu , this is what i started with :

    ...
    $priorities = array('low','normal','high'); 
    ...
    <select name="priority" id="priority">
       <?php 
          foreach ($priorities as $pro){
            echo '<option value="'.$pro.'">'.$pro.'</option>'; 
          }
        ?>
    </select>

It does the job but does not presist.

Now i want to get to something like this :

   <select name="priority" id="priority">
       <?php 
          $tel = 0;
          foreach ($priorities as $pro){
             echo '<option value="'.$tel.'"'.htmlentities('<?php if (isset($_POST[\'priority\']) && (int) $_POST[\'priority\'] === tel) { echo \'selected="selected"\'; } ?>').' >'.$pro.'</option>'; 
             $tel++;
          }
       ?>
    </select>

But that of course gives an error.

Anyone has any suggestions thx

Here’s how I often implement this:

<select name="priority" id="priority">
    <?php
    foreach ($priorities as $pro)
    {
        $selected = (isset($_POST['priorities']) && $pro == $_POST['priority']) ? 'selected' : '';
        echo '<option value="' . $pro . '" '.$selected.'>' . $pro . '</option>';
    }
    ?>
</select>

Just thought I’d point out you can actually shorten the ternary here like so

<select name="priority" id="priority">
    <?php
    foreach ($priorities as $pro)
    {
        $selected = ($pro == @$_POST['priority']) ? 'selected' : '';
        echo '<option value="' . $pro . '" '.$selected.'>' . $pro . '</option>';
    }
    ?>
</select>

Sorry I’ve got a bit of a thing for creating the shortest code possible 🙂
