        $("#judul_film").autocomplete({
        
        minLength: 1,
        source: function(req, add) {
            
            $.ajax({
                
                url: "<?php echo base_url();?>index.php/member/film_lookup",
                dataType: 'json',
                type: 'POST',
                data: req,
                success: function(data) {
                    
                    if (data.response == 'true') {
                        
                        add(data.message);
                        
                    }
                    
                },
                
            });
            
        },      
                      
    });
            
    });
    [removed]

<?php echo form_open('member/create_review');?>
    <p><label>Judul Film</label><br />
    &lt;?php
    $data = array('name' => 'judul_film', 'id' => 'judul_film', 'size' => '50');
    echo form_input($data);
?&gt;

autocomplete is already running, but i want to store 'id_film' to database, not 'judul_film'. how to change form input value to 'id_film'?

thanks for your help

judul_film = title_film
