Question

I’m really thinking I must have a badly formed php echo statement at the beginning of the but Dreamweaver is telling me that I have no syntax errors. My process.php is never getting called.

 $file = dirname(__FILE__) . '/customBook-index.php';
 $plugin_path = plugin_dir_path($file);
 $plugin_url = plugin_dir_url($file);

 <?php

     echo '<form method="post" action="'.$plugin_url.'process.php" />';

         echo'<select name="clients">';
        foreach($clientsArray as $client){
             echo'<option value="'.$client.'">'.$client.'</option>';
         }
     echo'</select>';
     echo '</form>';
    ?>

You don’t have to echo all of your HTML. You could also write:

<?php
    $file = dirname(__FILE__) . '/customBook-index.php';
    $plugin_path = plugin_dir_path($file);
    $plugin_url = plugin_dir_url($file);
?>
<form method="post" action="<?=$plugin_url?>process.php" />
    <select name="clients">
        <?php
            foreach($clientsArray as $client){
                ?>
                <option value="<?=$client?>"><?=$client?></option>
                <?php
            }
        ?>
    </select>
</form>

Maybe that’s easier for you to read and understand!? What is the output of $plugin_url.'process.php in your HTML? I think that either the path does not match or that you don’t submit your form correctly.
