[Resolved] Image field delete

I am trying to: create an image repeating field that only shows on frontend if there's an image attached. But if I delete images attached to the post with that image field, there's always a blank field

I visited this URL: local development, not yet online. You can see the template part code to show the image data on frontend here: hidden link

I expected to see: image data should only get on frontend if there's an image attached

Instead, I got: image data on frontend even when there's no image attached

Hi Alvora,

Thank you for contacting our support forum.

Actually what you need to do for this is to create a conditional statement that will display this section only if there are images in the field.

To do this have a look at the link below.

Please let me know if this helps.
Thanks,

Hi Shane,

Thank you for your reply.

In fact, the link didn't help. It only shows shortcodes, I'm using php to show my data in frontend.

You can see here hidden link that I used common conditional to assess for empty field. The problem is the field is not empty, although I've deleted all the images. Therefore, no image is shown but the code that wraps the image is.

I've seen several entries in the forum about this issue, and no definitive answer on how to solve it.

Can you point me to a code solution instead of shortcodes?

Thanks.

Hi Alvaro,

Could you add this to your code right after line 3

var_dump($galeria_imagens);

I would like to know the output given when the field is empty.

Thanks,
Shane

Hi Shane,

When I add the var_dump code, it prints like this:

array (size=1)
  0 => string '' (length=0)

Thanks.

Hi Alvaro,

Thanks so i see that even though the array is empty, its still giving us a value at the 0 index.

So to work around this we can check the 0 index to see if there is an actual value there and then do our conditional statement around that.

Evaluate the 0 index against an empty string.

Thanks,
Shane

Evaluate the 0 index against an empty string.

Can you give me an example on how to do that, please?

Thanks.

Hi Alvaro,

You should be able to do it by doing this.

 if (!empty($galeria_imagens[0])): 

Please let me know if this helps.

Thanks,

It seems to have worked!

Thanks a lot Shane!

Hi again Shane,

Just a quick question regarding the code above: if I want to limit the field presentation to 4 images, what should I do?

Thanks.
