Question

Usually with PHP and editing you click on a link that goes to a separate PHP page that has the “ID” of the entry you want to edit, you get the ID and populate your form base on this.

I would like to know how to do this if I am using a modal form? How do I get the ID get the records associated with it then populate the modal form.

sort of like this

//dropdown behavior for resp task and sub_task
$('#r_task_id').change(function() {
    var selected_task_id = $('#r_task_id').val();
    $.post("Assignment/populateSubTaskDropDown", { 'selected_task_id' : selected_task_id },//$_POST['selected_task_id']
             function(data){                
            $('#r_sub_task_id').empty();
            $.each(data, function(val, text) {
                $('#r_sub_task_id').append(
                    $('<option></option>').val(val).html(text)
                );
     });}, "json");

});//task

PHP code is:

$this->session->set_userdata('selected_sub_task_id', $this->input->post('selected_sub_task_id'));
    $json_resp_user = $this->assignmentModel->getResponsibleUsers($this->session->userdata('selected_sub_task_id'));

    $json = array();
    $json[0] = "-Select-";

    if( count($json_resp_user) >= 1 ){ //if there is more in the result than the -Select-
        foreach($json_resp_user as $detail){
            //$json[$detail->user_id] = $detail->first_name." ".$detail->middle_name." ".$detail->last_name;
            $json[$detail->user_id] = $detail->first_name." ".$detail->last_name;
        }
    }
    echo json_encode($json);

but for the whole form not just a dropdown.

I had a quick read of $.post() of jQuery and apparently that was what I meant =p

the part on your script with

id =” //Set this when opening the modal window

was where I was stuck on how to read that.

sorry if I wasn’t clear but thank you for taking the time and trouble to answer me.
