Empty custom fields.

Hello,

Thank you for mentioning this – I’ve needed this functionality of checking for empty custom fields before, so I added a new shortcode [if flag] for this purpose. Please see the latest update.

For example, this shows only products with serial numbers:

[loop type="product"]
    [if flag="serial_number"]
        Product: [content field="title"]<br>
        Serial number: [flag]<br>
    [/if]
[/loop]

The flag parameter specifies the field to check, and [flag] displays the value of that field.

I hope that can provide a solution.

Not sure if that’s working the exact way it should.

Take this example:

[loop type="brand" taxonomy="brand-category" value="non-gmo" columns="3" orderby="menu_order"]
[if flag="wpcf-brand-website"]
<div class="team-member"><a href="[flag]" class="inline">[content field="image" size="thumbnail"]</a><h4 class="light"><a href="[flag]" class="accent-color">[content field="title"]</a></h4></div>
[/if]
[/loop]

It should still show the logo and text, even though it doesn’t have a URL, right? However, it’s not showing it at all.

If I do something like this:

<a href="[if flag="wpcf-brand-website"][flag][/if]" class="inline">test</a>

It breaks the loop and nothing shows up.

Hmm..I made the [if flag] so it only shows its content when there’s a field value. It shows nothing if the field is empty.

However, I see you still want to show something even when the field is empty. I wonder how that can be achieved.. I guess it will have to be another loop for when the field is empty?

I’m thinking of adding a new [if no_flag] function, so you can separate it like:

[loop type="brand"..]
  <div class="team-member">
    [if flag="wpcf-brand-website"]
      <a href="[flag]" class="inline">
        [content field="image" size="thumbnail"]
      </a>
      <h4 class="light">
        <a href="[flag]" class="accent-color">
          [content field="title"]
        </a>
      </h4>
    [/if]

    [if no_flag="wpcf-brand-website"]
      [content field="image" size="thumbnail"]
      <h4 class="light">
        [content field="title"]
      </h4>
    [/if]
  </div>
[/loop]

So, I think I’ll implement this into the next update.

OK, please see the latest update to 0.9.0. I added [if no_flag] as in the example above.

Perfect! When I get done with this beast of a project, I’m going to dedicate some time, if you’d like, to helping figure out a pagination solution. Thanks again for the prompt responses and quick action, it is very much appreciated!

Great, I’m glad the solution worked for you. I think this function to check for an empty field will be useful, for situations as you mentioned like carousel, links, etc.

As for the pagination feature, just this week I’ve been working on jQuery pagination, so the bulk of it is completed. I believe I’ll build it further to be able to integrate with the [loop] shortcode. I’m thinking of releasing it as an add-on – if you’re interested in testing it out, please send me an e-mail: miyarakira(at)gmail.com, and I’ll let you know when it’s ready.
