Arrays in fields

Currently, there’s no general way to loop through an array in a field.

However, there is already looping with arrays, for example, in attachments, gallery field, field types in ACF, metabox in WCK, etc., so I imagine it’s possible to implement it somehow.

Is this array saved as a simple list [1,2,3] or with key value pairs?

Saved as key value pairs. If you could loop through an array in the same manner as the existing [repeater] syntax that’d be a slick addition.

OK, I’ll look into it and let you know when I’ve got something.

That’d be great!

Another question: do you know the specific keys in this array? For example, I’m imagining something like this:

[field-array field_name]
  [field key_name1]
  [field key_name2]
[/field-array]

Would that work?

That would be perfect!

OK, please see the latest update. I simplified it to:

[array field_name]
  [field key_1]
  [field key_2]
[/array]

Hmm, looking at this, I realized it’s not really a “loop” since it goes through only once. I hope that’s what you needed!

Hmm I’m not seeing any result (I downloaded the latest update).

Perhaps a screenshot of the array would help:

From this array I would expect this code:

[loop type='location']
[array socialicons]
  [field socialicons_network]<br>
[/array]
[/loop]

to produce:

facebook
twitter
google-plus

Hmm..looks like you have a field that’s structured like this:

Array
(
    [0] => Array
        (
            [social_icons_url] => '/'
            [social_icons_network] => 'facebook'
            [social_icons_flyoutcontent] => 'etc.'
        )
    [1] => Array..
    [2] => Array..

..whereas currently [array] expects something simpler, like:

Array
(
    [key_1] => value_1
    [key_2] => value_2
)

Yeah..I was afraid that a shortcode to parse arrays can get complicated, since there are many different ways data can be stored in a field.

OK, I’ll add a parameter that will loop through each array in the field.

So, please try the latest update with:

[loop type="location"]
  [array socialicons each="true"]
    [field socialicons_network]<br>
  [/array]
[/loop]

That should loop through each array.

That works great, thank you!
