Accessing multiple value from a custom field

Using a fresh WordPress install, I’ve added to a post, a custom field called “Colour” and assigned it a value “Red”, and another with a value of “Green” (screenshot).

I can display the first value using [field Colour] but don’t know how to access the second value “Green”. I’ve tried the following:

1. [array Colour] (and with each=true)
2. [for each=Colour]

@iantresman

personally I’d use an ACF repeater. I’m not sure CCS is set up to process this.

looking at this it would need a way to pass single=false to get_post_meta and return an array maybe: https://developer.www.ads-software.com/reference/functions/get_post_meta/

(Would be great if we could use [pass array=some_field] and have it assume therefore some_field needs to be returned as the array)

the code below isn’t future proof but gives you some option until the developer updates the plugin:

in the plugin include/core/content.php line 1927, you can try set this to false instead of true at the end
$result = get_post_meta($post_id, $field, false);

This returns the field as a comma delimited string though not an array (not sure why), so the [pass array...] functions don’t work and I’m not sure what knock on effects making this change would have either

But you could then use string functions though to get values

Colour 1: [format split="," part=1][field colour][/format]
Colour 2: [format split="," part=2][field colour][/format]

or..

[pass field=colour]
Colour 1: [format split="," part=1]{COLOUR}[/format]
Colour 2: [format split="," part=2]{COLOUR}[/format]
[/pass]

but it’s kind of messy solution

it also gives you access to a pass loop

pass list check:

[set temp][field colour][/set]
[pass vars]
[-pass list='{TEMP}']
{-ITEM}
[/-pass]
[/pass]

or more simply…

[pass field=colour]
[-pass list='{FIELD}'] // creates a list from the comma separated values
{-ITEM}
[/-pass]
[/pass]

hope that’s of use

It would be great if @miyarakira could look into this.

with the above change to content.php to allow for field arrays, also it seems in includes/modules/pass.php that the code below is what breaks the [pass array...] functions

($field_value is being returned as a string not an array with the slower version)

// Predefined or custom field
} else {
   // $field_value = CCS_Content::get_prepared_field( $field, $post_id );
   // Slower but will get date format, etc.
   $field_value = CCS_Content::content_shortcode($atts);

if you swap those comments around so it uses the get_prepared_field version, this code now works

[pass array=colour]
Colour 1: {0}, 
Colour 2: {1}
[/pass]

(Is it possible to get the length?)
(again it needs the previous modification for get_post_meta to return an array)

@miyarakira another potential extra change:

on line 2501 of includes/core/content.php

} else {
  $id = do_shortcode('[field id]');
  $array = get_post_meta( $id, $field, true ); // <== change to false 
}

this then returns the field as an array as expected so this now works:

[array field=colour]
[field value]
[/array]

Hi @iantresman – I’m working with @codemonkeynorth to implement a solution. Will let you know when it’s ready.

Thank you very much, appreciated.

Hello iantresman,
could You try this code:

[array cfs_writer each=true]
[field value]
[/array]

.. or..

[array Colour each=true]
[field value]
[/array]
