Reply To: Update field for multiple choose with array

Ok i find the issue,

for valid the update field, we must return only the value (get_field without format), like :

	$arr = array(
			  "0" => "test1",
			  "1" => "test2"
		  );

Then the core ACF will save the field correctly with value.

But, i use the get_fields() in my API, then the developper of APP from my WordPress, return all fields with value/label, so i must modified the core of ACF.

like :
includes\fields\class-acf-field-select.php – line 526

		
if( is_array($value) ) {
    //$value = array_map('strval', $value); // OLD // remove array and up the value in parent array

    // will print the array and select only the value
    foreach ($value as $key => $val) {
        // check if have more 2 characters, some field return 1 letter :/
        if ( strlen($val['value']) > 2 ) {
		$value[$key] = $val['value'];
	} else {
		$value = array_map('strval', $value);
	}
    }
}

That quick code is used for select field and checkbox field.

Can you add some filter for help developper ?

thanks,
Best Regards, Mat.
