I am filing this as support request since I cannot tell for sure they are a bug, but I am experiencing these problems with Mini Panels.

Issue #1: Cannot delete a Mini Panel. Just hit delete, I am asked if I am sure, then confirm. Only returns to the main MiniPanels list page and the one that I intended to delete is still there. No messages.

Issue #2: Mini Panels are OK in the preview or if added as a pane in a panel page. But as a block is not showing. There are no visibility rules. The block is set to show on all pages. Again, no error messages.

Issue #3: Creating a Mini Panel

Select a Layout. Hit Next and in Content there is no region shown
I go back to Layout and select a layout again and hit next. I get this message

warning: Invalid argument supplied for foreach() in .../modules/panels/includes/display-layout.inc on line 211

and all these messages when saving

    * warning: Invalid argument supplied for foreach() in .../modules/panels/includes/display-layout.inc on line 211.
    * warning: Invalid argument supplied for foreach() in .../modules/panels/panels.module on line 694.
    * warning: Invalid argument supplied for foreach() in .../modules/panels/includes/plugins.inc on line 417.

And no layout is generated

The way I found to generate the layout is:

- Start the creation select a layout
- provide name and title. Save and Proceed
- Click Save and Proceed in Context. Get to Content where there is no area to put content in.
- Go back to Settings. Nothing is shown in name and title nor in layout. Enter name and title and hit Save.
- Exit the edit forms and go to the Mini Panels list. You have the new MiniPanel with no layout shown.
- Hit Edit, go to layout, select the layout and when saving get the messages above.
- If you continue hitting save, the second time the messages does not appear and the layout is created (when you go to the content the regions is there). From here on I can change the layout without any messages. Seems to happen only the first time.
On PHPMyAdmin I can see that severan NULL Entries are created in the MiniPanels Table

Thank you.

Exactly same issue, subscribing.

Almost nothing is working for mini panels. Alpha3 had also this very same problem.

Tx.

Same problem here - although it didn't appear until I updated to alpha 4 last night. I downgraded to alpha 3 and it works again.

Bambor, How did you downgrade? I removed the directory, installed the alpha3, did not run update.php. No luck. The problems are the same.

As far as I could get, I found something of why blocks are not being displayed.
On the implementation of hook_block (panels_mini_block) when option is 'view' the function that is called is

$panel_mini = panels_mini_load($delta);
this returns an empty variable

On function panels_mini_load the ctools function for querying table "panels_mini" is called on this sentence.

$result = ctools_export_load_object('panels_mini', 'names', array($name));

The arguments should match the key defined in the schema for the table 'panels_mini'. The problem is that the key is 'name' and we are sending the $delta that should be matched against 'pid'

By making the following modification to export.inc in ctools/includes I could get mini panels to work. Still cannot delete the existing mini panels

It is not a nice one, is done in another module, but at least I don't have to revert to alpha2 and rebuild everything (I learned the hard way to backup the database previous to updates)

function ctools_export_load_object($table, $type = 'all', $args = array()) {
  static $cache = array();
  static $cached_defaults = FALSE;
  static $cached_database = FALSE;

  $schema = ctools_export_get_schema($table);
  $export = $schema['export'];

/*************************************************************/
/* this is the fix */ 
  if (($table == 'panels_mini')&&(is_numeric($args['0']))) {
    $export['key'] = 'pid';
  }
/*************************************************************/

  if (!isset($cache[$table])) {
    $cache[$table] = array();
  }

  $return = array();

I'm getting the same issues with node panels...

* warning: Invalid argument supplied for foreach() in .../modules/panels/panels.module on line 694.
* warning: Invalid argument supplied for foreach() in .../modules/panels/includes/plugins.inc on line 417.
* warning: Invalid argument supplied for foreach() in .../modules/ctools/includes/export.inc on line 255.

I updated to the latest ctools and alpha4 of panels and I still get the errors.

Sancho,

I don't claim to be an expert, so I wouldn't necessarily recommend doing anything the way I have!

All I did was delete the panels folder and replace it with the alpha 3 version. Then I ran update.php, even though it didn't see any new updates. I'm sure I also cleared the cache as well.

That seemed to do the trick for me, hope it is of some help.

@bambor - did you also downgrade ctools?

@qbnflaco

Nope. I didn't downgrade ctools. My install is currently running:
Chaos tool suite 6.x-1.0-alpha3
Panels 6.x-2.0-alpha3
Views 6.x-2.3

FYI: I updated to dev and no longer have issues with the node panels, but am experiencing the same issues as you guys with the mini panels.

After applying the patch, I'm still getting the error, but in different files. I'm getting the following both when I try to edit the content for the mini panel and after getting it there, when I try to display the page with that mini panel on it. It works correctly when I have a layout like two column, but gives me the errors when the flexible layout, which is what I use for almost everything :(

* warning: Invalid argument supplied for foreach() in /var/www/drupal/sites/all/modules/panels/plugins/layouts/flexible/flexible.inc on line 569.
* warning: Division by zero in /var/www/drupal/sites/all/modules/panels/plugins/layouts/flexible/flexible.inc on line 624.

* warning: Invalid argument supplied for foreach() in /var/www/drupal/sites/all/modules/panels/plugins/layouts/flexible/flexible.inc on line 319.

Hopefully this can be easily patched and quickly.

I'm 90% sure that's a different bug that results when you try to add a 'fixed' element as the first element in an empty row. I need to fix that =)

merlinofchaos’s picture

merlinofchaos commented

In any case, the answer is simple. Don't add a fixed element first, and if you did, you should be able to remove it okay.

cgillogly commented

@merlinofchaos All of the elements I have added in my mini panels, and panels for that matter, are fluid, not fixed. I use flexible layout for everything and fluid elements with percentages in my setup. After applying the patch above I am able to create and modify my mini panels without problem, but I have to use one of the standard layouts and not flexible or I get the error I posted above.
