[Résolu] Using ‘wpv-view wrap’ shortcode to list post fields with alphabetic index

[Robert Campbell]

I am displaying a custom post type in a responsive grid loop based on the support ticket https://toolset.com/forums/topic/definitive-method-for-creating-truly-responsive-grid-loop-wequal-height-cells/

You can see my test layout at hidden link

I am trying to find a way to display the grid so that each alphabetic section starts in a new row, so:

A
all posts starting with the letter 'A' (in a responsive grid layout)
B
all posts starting with the letter 'B' (in a responsive grid layout)

etc.

I plan to create 'dummy' posts with the title of each of the alphabet letters. In my test layout I have created:

A dummy post with the post title 'M', so it always appears before all the other 'real' posts starting with the letter 'M'.

A 'dummy' post with the post title 'N', so it always appears before all the other 'real' posts starting with the letter 'N'.

This works okay. I have used conditional output to detect the 'dummy' post (has no image) and format the dummy post to act as an alphabetic section header.

I need help to force each alphabetic section to start in a new row. So as an example from my test layout for the letters 'M' and 'N',

After the post titled 'IGS Audio', the display should start on a new line with:

'M' (dummy post)
M-Audio, Mackie, Magix, Marshall, MOTU
'N' (dummy post)
Natal, Native Instruments, Neat Microphones, Negri Cases, Nektar, Neumann

Here is my view code

Dear Robert,

You might consider custom JS codes, for example:

jQuery(function($) {
    $('div.alphabet').parent('div.card').css('clear', 'both');
});

More help:
hidden link

[Robert Campbell]

Dear Luo

Thank you for the suggested JS code which I have tried.

Two issues:

1. I want to have the alphabetic header on it's own line, so like:

'M'
M-Audio, Mackie, Magix, Marshall, MOTU
'N'
Natal, Native Instruments, Neat Microphones, Negri Cases, Nektar, Neumann

2. The wpv-item index needs to be reset back to 1 at the start of each new alphabetic section, otherwise the grid layout is destroyed. Have a look at hidden link and where the 'MOTO' image is appearing on a new line which is wrong.

Regards

Robert

Please provide your test site credentials in below private message box, also point out the problem view URL, thanks

There isn't such kind of feature within Views plugin, I have done below modification in your website:
Edit the view "companys2":
hidden link

1) in section "Loop Editor", change the codes as below:

...
<!-- wpv-loop-start -->
<div class="container wpv-loop js-wpv-loop">
<div class="row spacing">
<wpv-loop>
    <div class="col-xs-6 col-sm-3 col-md-2 col-lg-1 card">
      [wpv-conditional if="(NOT( empty($(wpcf-company-logo)) ))"]
        <div class="card2 [wpv-post-slug]">
          <a href="[wpv-post-url]">
          [types field='company-logo' title='%%TITLE%%' alt='%%ALT%%' size='custom' width='400' height='400' resize='crop'][/types]
          </a>
        </div>
        [wpv-post-title]
      [/wpv-conditional]
      [wpv-conditional if="(empty($(wpcf-company-logo)) )"]
        <div class="alphabet">
          [wpv-post-title]
        </div>
      [/wpv-conditional]
    </div>
</wpv-loop>
  </div>
</div>
<!-- wpv-loop-end -->
...

2) modify the JS codes as below:

jQuery(function($) {
    $('div.alphabet').parent('div.card').css('clear', 'both');
	$('div.pmc').parent('div.card').css('clear', 'both');
});

It works like this:
- if it is HTML div tag ".alphabet", change a new line
- if it is PMC change a new line.

It is only an example, for your reference.

Dear Luo

Thank you for the suggested code.
The JS for the alphabetic purpose works fine.

However (if I understand correctly?) the use of JS derived from the post slug is not workable. This would mean I would have to manually add JS for each time an image required to go to start of a line.

The use of this view is dynamic so there will be additional images being added every day.

Have I misunderstood the intended use of the JS code derived from post slug?

Robert

Yes, you are right, as I mentioned above there isn't such a built-in feature within Views, the custom JS codes I provided above is only an example, in your current demo site, there isn't alphabet post "P", so you would have to manually add JS codes to change a new line in "PMC" post.

If there are lots of posts, you will need to consider to setup alphabet posts for each "letter":
a, b, c, d,e ...

Then the JS codes will be able to change the line in each alphabet post automatically.

Dear Luo
Thanks for trying to find a solution. I'll explore another way to make the alphabetic listing feasible.

Robert
