Need help getting a certain value out of a multi dimensional array

Question

I'm looking to retrieve a specific meta value for users from the Wordpress types plugin. I know the value is stored in a wpcf-team-experience-member-type. This is a checkbox option and I'd like to retrieve a list of all selected values.

Right off the bat if I do something like:

var_dump(get_user_meta($user->ID, 'wpcf-team-experience-member-type'))

I get something like this:

array(1) { [0]=> array(1) { ["wpcf-fields-checkboxes-option-f4fe375f6cad3c44eff97e6e6f16deb2-1"]=> array(1) { [0]=> string(7) "student" } } }

wpcf seems to put all of its values inside of an array, and on top of that the checkbox values are stored in an array as well. In this case, the value I'm looking for is 'student' but that array might have multiple values.

How would I go about retrieving it? Thank you!

Answer 1

The reason you get the "First" Array is that you don't use the "single" option of the get_user_meta function. Try this:

$arr = get_user_meta($user->ID, 'wpcf-team-experience-member-type',true);
$options = array();
if(is_array($arr)){
    foreach($arr as $key => $value){
        foreach($value as $arrvalue){
             $options[] = $arrvalue;
        }
    }
}
var_dump($options);

This should dump all the options that maybe are in there.

Answer 2

The array is just contain another array that contains the array where the 'student' is located.

You can use array_keys() to return all the keys or a subset of the keys of the array and access the string 'student' with integer keys instead of an int-string-int [0]["wpcf-fields-checkboxes-option-f4fe375f6cad3c44eff97e6e6f16deb2-1"][0], like this:

$arr = get_user_meta($user->ID, 'wpcf-team-experience-member-type');
$keys = array_keys($arr);
var_dump($keys[0][0][0]);

Answer 3

Try var_dump(get_user_meta($user->ID, 'wpcf-team-experience-member-type'), true).

The third parameter for get_user_meta (called $single) specifies whether to return a single value (true) or an array (false). The default is false.
