Undefined index: items_per_page

Yup, I'm getting similar errors:

Could you please provide exact settings you have applied in order to reproduce this bug?

I think it was just with enabling it. But I'll have to get back to you when I've got time to try this again.

getting the same error as original post.

same here on D7 - subscribing.

The problem is when you change create a view to display all items. The new pager plugin options doesn't set the items_per_page option when you are displaying all items (since all pages pager is a separate pager plugin).

There might be a bigger problem here, because a lot of the code assumes items_per_page option exists, so a lot of the pager code might need to be upgraded to the way views 3.x handles pagers.

Fixed all notices related to item_per_page.

Here's a new patch that applies cleanly against HEAD

Looks like this is also covered in #1141846: Undefined index errors. Happy to mark that issue as a dup.

That would make sense as there are patches here. Thanks @seanberto!

As this is the oldest issue which discusses the problem, I'm reopening this (needs review) and closing the others as duplicates.

A workaround for those who don't wish to patch the module themselves is to set the pager to display a very large amount of items.

subscr

Committed. Thanks!

Hi! I'm using the -dev version from 2011-May-16 and the error is still reproducibile.

Hi, I've got this error when try to using version from git (2011-August-08)

Notice: Undefined index: draggableviews_delta in draggableviews_handler_native->init() (line 14 of /home/yarroha/www/d7/htdocs/sites/all/modules/draggableviews/implementations/draggableviews_handler_native.inc).

I encountered this error after adding a Sort criterium (Node: Title - ascending) on top of the already added Draggable table-criterium, thus having two sort criteria:

• Node: Title (ascending)
• Draggable table (can't remember the exact wording)

The critical point of this behaviour is that I can't open that very view anymore. When clicking the view in the Views overview (admin/structure/views/), I get this error:

    Notice: Undefined index: draggableviews_delta in draggableviews_handler_native->init() (line 14 of /var/www/html/sites/all/modules/draggableviews/implementations/draggableviews_handler_native.inc).

I'm getting an Ajax error as well when checking both the "Show input fields"-options in the settings of Draggable Table (Format) and submitting the settings:

An AJAX HTTP error occurred.

I got it to work in the preview, but I can't save my view. Hitting the Save button results in another Ajax error:

Can I use this-product to help avoid scars?          
Yes. But if the skin has been ruptured you cannot avoid a scar. You can make it less visible. You can use this-product only on completely healed wounds.          
012
How does it work?          
this-product releases a transparent, thin and discrete silicone film and creates as such a protective barrier for the healing of scars, while maintaining the skin’s moisture balance.          
012
Can I use this-product on all parts of the body?          
You can use the product all over the body and face.          

However, if I close the admin overlay and navigate to the view again, everything's still there, ànd if I hit the Save button now it causes no trouble.

In case it could help anyone, attached you'll find the configuration that works for me. It seems DV it has some issues with the Ajax environment of Drupal though.

Now we're getting the following error on the public part of the website (being logged out):

Warning: Division by zero in draggableviews_views_pre_render() (line 387 of /var/www/html/sites/all/modules/draggableviews/draggableviews.module).

Since we're dealing with a rather tight time schedule, we've decided to wait to use the Draggable Views module until there's a stable Drupal 7 version.

#1199468: Notice: Undefined index: items_per_page in _draggableviews_click_sort() marked as duplicate of this issue.

I can confirm the two errors that knalstaaf has gotten in #21 and #22. I got the first error initially and then after using the configurations that were shown in #23 when I tried to save I got the second error.

This is an issue for 7.x-1.x-dev, which is unsupported now. There is no problem like this in 7.x-2.x-dev. Pager currently doesn't work. See #1551230: Add pager support for DraggableViews tables

items_per_page argument is removed in the latest 7.x-2.x-dev. #1901170: Never save items_per_page argument
