Hi
I am developing an app for work. I have many controllers needing the same xajax function I wrote. I tried to put these functions in my MY_Controller.php file (gets extended on every controller), but I don't think these functions are accessible (cause it's not working).

I register these functions in the controllers index(). Do I need to register them in My_Controller.php??

How can I globalize these AJAX functions I wrote. I want to be able to re-use them.

Thanks

I think what you want to do is put them in a library instead of extending the controller, say you call it "Ajax". Then in the autoload config add your library to the list and all your functions will be available via $this->ajax->some_function()

OK I could give that a go. What happens is I have a select list which a user chooses an option. On choosing that option, it auto populates the second select list like this.

Code:
onChange=\"xajax_get_tasks(this[this.selectedIndex].value);


I tried putting into a library. It still seems like it cannot access those functions.

Any ideas?

Isn't that javascript?

El Forum

[eluser]LifeSteala[/eluser]
Yeah, that is on the HTML side. If I put the function inside the actual controller, that JavaScript can access the function and do what I need it to do.

I put that function in a library as you mentioned, and loaded it, however it still doesn't work.

So I'm guessing that JavaScript cannot access the function inside the loaded library?

So is it possible to re-use a AJAX function across many controllers?

[eluser]geckzilla[/eluser]
You just need to include the javascript file in your template header... codeigniter is php only.

I've included the JavaScript. I register the functions in the controllers constructor. Here's my controller.

Code:
class Entertime extends MY_Controller
{
    function Entertime()
    {
        parent::MY_Controller();
        
        $this->load->model('timesheets');
        $this->load->model('clients');
        $this->load->model('projects');
        $this->load->model('tasks');
        
        $this->load->library(array('validation', 'xajax', 'globalajax'));
        
        $this->load->helper('url');
        $displayoutput = "";
        $type = "";
        $name = "";
        $status = "";
    }
    
    
    function index()
    {

        $this->xajax->registerFunction(array('get_projects',&$this,'get_projects'));
        $this->xajax->registerFunction(array('get_tasks',&$this,'get_tasks'));
        $this->xajax->registerFunction(array("auto_suggest", &$this, "auto_suggest"));
        $this->xajax->processRequest();
        $data['xajax_js'] = $this->xajax->getJavascript(base_url());
                
                // More code here
        }
}

Here's my library

Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

    class Globalajax
    {
    
        function Globalajax()
        {
            log_message('debug', "Global Ajax Functions Class Initialized");
        }

        // Function: get_projects - Public
        // Gets projects depending on what client is selected. AJAX
        //-----------------------------------------------------------------------------------------------
        function get_projects($clientName)
        {
            $proj_query = $this->projects->getProjectsAjaxSearch($clientName);
            
            $output = '<label for="project">Project: </label>';
            $output .= "<select name=\"project\">\n";
            
            if ( $proj_query->num_rows() > 0 ) {
                $output .= '<option selected="selected"></option>';
                
                foreach($proj_query->result() as $rows)
                    $output .= "<option value=\"{$rows->project_id}\">{$rows->project_name}</option>";
            }
            else
                $output .= '<option selected="selected">No projects available</option>';
            
            $output .= '</select>';
            
            $objResponse = new xajaxResponse();
            $objResponse->Assign("optionProjects","innerHTML", $output);
            return $objResponse;
        }
    
        // Function: get_tasks - Public
        // Gets tasks depending on what project is selected. AJAX
        //-----------------------------------------------------------------------------------------------
        function get_tasks($projectID)
        {
            $task_query = $this->tasks->getTasksAjax($projectID);
            
            $output = '<label for="task">Task: </label>';
            $output .= '<select name="task">\n';
            
            if ( $task_query->num_rows() > 0 ) {
                $output .= '<option selected="selected"></option>';
                
                foreach($task_query->result() as $rows)
                    $output .= "<option value=\"{$rows->task_id}\">{$rows->task_name}</option>";
            }
            else
                $output .= '<option selected="selected">No tasks created</option>';
            
            $output .= '</select>';
            
            $objResponse = new xajaxResponse();
            $objResponse->Assign("optionTasks","innerHTML", $output);
            return $objResponse;
        }
        
        // Function: get_tasks - Public
        // Gets tasks depending on what project is selected. AJAX
        //-----------------------------------------------------------------------------------------------
        function auto_suggest($val)
        {
            $objResponse = new xajaxResponse();
    
            $result = "";
    
            if (isset($val) && $val != "")
            {
                $query = $this->clients->searchClients($val);
    
                if ($query->num_rows() > 0) {
                    foreach ($query->result() as $row) {
                        $result .= "<div title='". $row->client_name . "' onmouseover='[removed]suggest_over(this);'";
                        $result .= " onmouseout='[removed]suggest_out(this);'";
                        $result .= " onclick='[removed]set_search(this.title);' class='suggest_link'>";
                        $result .= $row->client_name;
                        $result .= "</div>";
                    }
    
                    $objResponse->Assign("client_result", "style.display", 'block');
                    $objResponse->Assign("client_result", "innerHTML", $result);
                }    else {
                    $objResponse->Assign("client_result", "style.display", 'none');
                }
            }    else {
                $objResponse->Assign("client_result", "style.display", 'none');
            }
    
            return $objResponse;
        }
    }

Well as though you have
[code]
class Globalajax
{
/// Your codes.....
function Globalajax()
{
log_message('debug', "Global Ajax Functions Class Initialized");
}
function get_tasks($projectID)
{
//Generate List drop down
}
}
[code]
it's possible to call this function inside javascript function like yoursite.com/globalajax/get_tasks(5)

[eluser]LifeSteala[/eluser]
I have managed to solve this using MY_controller.

I created a new function called load_ajax() inside MY_controller. In this function I register the ajax functions and process the request.

The actual controller then calls load_ajax() and then loads the JavaScript.

Thanks to those who helped.
