Hello:
I have the following problem: When I add a field to upload images on content type Story. Using CCK and FileField.

On the home page this error:
warning: strpos() [function.strpos]: Empty delimiter in /home/citycas/public_html/sites/default/themes/inf08/template.php on line 92.

I hope your help.
I tried using another theme and do not get this error.

Details of the Line 92 in my templates.php:

      // experimental code to handle CCK fields
      foreach ($content as $key => $value) {
        if (substr($key, 0, 6) == 'field_' && strpos($vars['content'], $vars[$key . '_rendered']) !== FALSE) {
          $content['cck_' . $key] = array(
            '#weight' => $content[$key]['#weight'],
            '#value' => $vars[$key . '_rendered'],
            '#title' => '',
            '#description' => '',
          );
        }
      }
      
      inf08_prepare_content($content);

      $vars['content'] = drupal_render($content);

I have the exact same issue. Any thoughts on how to solve this?

Hi,
after tinkering with this for a while I believe I have a solution. I am no PHP coder so if anyone sees something wrong with this code then please correct me. The issue is caused by a user not having permission to see a cck field. When giving the user permission to be able to view the field the error does not show. BUT of course there are times when you do not want a user to be able to see a field.

So this is what I did:

           // experimental code to handle CCK fields
            foreach ($content as $key => $value) {
                if (!empty($vars[$key . '_rendered'])) {//added by phantastes
                    if (substr($key, 0, 6) == 'field_' && strpos($vars['content'], $vars[$key . '_rendered']) !== FALSE) {
                        $content['cck_' . $key] = array(
            '#weight' => $content[$key]['#weight'],
            '#value' => $vars[$key . '_rendered'],
            '#title' => '',
            '#description' => '',
                        );
                    }
                }//added by phantastes
            }

I added the "if (!empty($vars[$key . '_rendered'])) {" line and of course the closing "}".

Let me know if this solves it for you.

All the best.

Hi,
I've added comments in the code to show what I've added.

But here it is:
Code that causes problem:

if (substr($key, 0, 6) == 'field_' && strpos($vars['content'], $vars[$key . '_rendered']) !== FALSE) {

I believe it's the "$vars[$key . '_rendered']" bit that is the trouble maker. When it returns nothing you have the issue with the empty delimiter.

So I surrounded that if statement with this check to check that $vars[$key . '_rendered'] is not emtpy:

 if (!empty($vars[$key . '_rendered'])) {

   your code here

}

I hope this helps!
