Hey all,
I built a search form using acf fields and I have problems.
The issue is as so: I have a select field in the site frontend, the select is an acf field That I want to filter by.
What I want to do is to receive all the values of the field when I select the all rooms option that added manually.

I read theis post and I think that the question is simillar.

select retreive code:

 <div>
                    <?php 
                    $rooms_field_key = "field_59ae9e2370a0b";  //prop_rooms
                    $rooms_field = get_field_object($rooms_field_key);
                    
                        if( $type_field )
                            {
                                echo '<select name="' . $rooms_field['key'] . '">';
                                ?>
                                    <option value="">all rooms</options>
                                <?php
                                    foreach( $rooms_field['choices'] as $k => $v )
                                    {
                                        echo '<option value="' . $k . '">' . $v . '</option>';
                                    }
                                echo '</select>';
                            }
                        ?>
                        
                        </div>

This is the args var in search.php page:

if (isset($_GET['front-side-prop-search'])){
    $args = array(
        'posts_per_page' => 9,
        'post_type'	=> 'property',
        'meta_query'    =>  array(
            'relation '  => 'AND',
            array(
                'key'	=> 'prop_city',
                'value'	=> $city,
                'compare'  => '=',
                'relation' => 'OR',
                    array(
                    'key' => 'prop_city',
                    'compare' => 'NOT EXISTS'
                    )
            ),
            array(
                'key'	=> 'prop_rooms',
                'value'	=> $rooms,
                'compare' => '=',
                'relation' => 'OR',
                    array(
                    'key' => 'prop_type',
                    'compare' => 'NOT EXISTS'
                    )
            ),
           
        ),
    );
};
