Views Merge Rows and pagination

There is a bug in the patch. I added second view mode for Data Export and changed the pager limit. This patch still uses the pager limit of the first view mode. The culprit is the line:

$items_per_page = (int)$view->display[$view->tag]->display_options['pager']['options']['items_per_page'];

I have changed it to the following:

$items_per_page = (int)$view->display[$view->current_display]->display_options['pager']['options']['items_per_page'];

Patch is attached.

Patch #6 doesn't work. Here is the updated patch if the current display has different number of items in the pager or has no pager.

I am having issue #2502879: support views merge rows iterating though views merged rows with https://www.drupal.org/project/views_rules. From your observations

It appears the problem with pagination output is that Views Merge Rows uses the views_pre_render hook to only change the output of the query that already ran. Views doesn't see the change and still sees the original number of rows.

It seems rules still getting actual rows instead of merged single row with this patch applied.

use case:
task: send notification through sms
setup: build views of phoneno ,Grouping field: Message(not aggregation) exclude from display
sample output:

row1|123456789,456789870
row2|145869872,241569878

Hello @neeravbm

Thank you for the patch. it works perfect.

Just a few things though:

1. I added fetching "items_per_page" from url as well.
2. Total number of results was the same as "items_per_page". so for example, if there are 10 results and items_per_page = 2 then the total_rows = 2 as well. In above example, the total_rows needs to be 10 so fixed that.

Thanks again !!

Sorry, first time submitting patch.
Had wrong diff lines on top. made the correction.
Thanks !!

#12 does not apply but probably works

placed patch from #12 in module directory and did git apply -v [patchname].patch but patch did no apply with following error messages

Checking patch views_merge_rows.module...
error: while searching for:
  $table = theme('table', array('header' => $header, 'rows' => $rows));

  $form['table_fieldset'] = array(
    '#title' => t('Configure merging options for the fields'),
    '#type' => 'fieldset',
    '#dependency' => array('edit-options-merge-rows' => array(1)),

error: patch failed: views_merge_rows.module:49

Applying the patch by hand and clearing cache seems to work

#7 patch applies and seems to work

I also applied #7 patch which applied without me having to do it manually
this also seems to work so I am going to have to go with #7 patch

applied patch to latest DEV version (as its usually the case)

please commit #7

Same patch for 1.0-rc1

I have used #16 patch for 1.0-rc1.
It is working for me if number of result are less then 500,But it is not working if number of result are more then 500 and display White blank screen.
