# Empty custom fields.

* Any thought on giving an ability to check if a custom field is empty? Or any
field for that matter. I keep trying to use this for some stuff and I want to
because it’s nice and simple and something I can explain to my clients, however,
I keep hitting these logic walls.
* I’ve got it looping through to build a carousel of logos, but some have URLs
and some do not from a custom field.
* Thoughts?

* 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"]
Serial number: [flag]
[/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"]
[/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:
* `test`
* 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"..]
[/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.
