Allow ‘custom’ values to be added in select field

Hello,

Thanks for the feedback! I’m glad you enjoy ACF Extended ??

Unfortunately, there is no way to save both value & display text at the same time using the “Allow custom value” settings in the Select field. There’s no “Global pattern” that could match every needs. Some users may would like to save the custom value Remember this : you are amazing for example, which would end up splitting the value to Remember this.

You can add your own pattern tho, using the acf/update_value hook. See documentation: https://www.advancedcustomfields.com/resources/acf-update_value/

Here is an example usage for your case, inspired by the ACF Checkbox Field which let user save it’s own custom value in the field settings. This code will split the custom value with the pattern value : Text:

add_filter('acf/update_value/name=my_select', 'my_acf_select_split_custom_value', 10, 3);
function my_acf_select_split_custom_value($value, $post_id, $field){
    
    // Force value to array
    $_value = acf_array($value);
    
    // Vars
    $values = array();
    $choices = $field['choices'];
    
    // Updater
    $update = false;
    
    // Construct Choices
    foreach($_value as $v){
    
        // Explode value
        $_v = explode(' : ', $v);
        
        $values[] = $_v[0];
        
        // value : text wasn't found
        if(!isset($_v[1]))
            continue;
    
        // ignore if already eixsts
        if(isset($choices[$_v[0]]))
            continue;
        
        $update = true;
    
        // unslash & sanitize (remove tags) value
        $_v[0] = wp_unslash($_v[0]);
        $_v[0] = sanitize_text_field($_v[0]);
    
        // unslash & sanitize (remove tags) text
        $_v[1] = wp_unslash($_v[1]);
        $_v[1] = sanitize_text_field($_v[1]);
    
        // append
        $choices[$_v[0]] = $_v[1];
        
    }
    
    if($update){
    
        // Inspired by Checkbox field
        $selector = $field['ID'] ? $field['ID'] : $field['key'];
        $field = acf_get_field($selector);
    
        // bail early if no ID (JSON won't be updated)
        if($field['ID']){
            
            $field['choices'] = $choices;
            
            // Save field choices
            acf_update_field($field);
            
        }
        
    }
    
    if(is_array($value)){
        
        return $values;
        
    }
    
    return $values[0];
    
}

This will save custom values into the field settings choices UI, just like Checkbox Field. Please keep in mind that it won’t work with Json Sync, you have to keep your field group in the DB.

I may add a setting in the future with few patterns to pick for that specific case.

Hope it helps!
