I want to use ajax in my calendar.php file but how do i get started?

[Frank H. Shaw]

The following i am going to start to modify the calendar.php and I will start to post the changes as i do them.

My first is where in the calendar.php do I put my first part of this the following:

PHP Code:


<?php

// ######################## SET PHP ENVIRONMENT ###########################
error_reporting(E_ALL & ~E_NOTICE);

// ##################### DEFINE IMPORTANT CONSTANTS #######################
define('THIS_SCRIPT', 'calendar');
define('GET_EDIT_TEMPLATES', 'edit,add,manage');

// #################### PRE-CACHE TEMPLATES AND DATA ######################
// get special phrase groups
$phrasegroups = array(
    'calendar',
    'holiday',
    'timezone',
    'posting',
    'user'
);

// get special data templates from the datastore
$specialtemplates = array(
    'smiliecache',
    'bbcodecache',
    'noavatarperms',
);

// pre-cache templates used by all actions
$globaltemplates = array(
    'calendarjump',
    'calendarjumpa',
    'calendarjumpb',
    'calendarjumpbit',
);

// pre-cache templates used by specific actions
$actiontemplates = array(
    'displayweek' => array(
        'calendar_yearly',
        'calendar_monthly',
        'calendar_monthly_week',
        'calendar_monthly_day',
        'calendar_monthly_day_other',
        'calendar_monthly_birthday',
        'calendar_monthly_event',
        'calendar_monthly_header',
        'calendar_smallmonth_header',
        'calendar_smallmonth_week',
        'calendar_smallmonth_day',
        'calendar_smallmonth_day_other',
        'calendar_weekly_day',
        'calendar_weekly_event',
        'calendar_weekly',
        'calendar_showbirthdays',
        'CALENDAR'
    ),
    'displayyear' => array(
        'calendar_smallmonth_day_other',
        'calendar_smallmonth_header',
        'calendar_smallmonth_week',
        'calendar_monthly_event',
        'calendar_smallmonth_day',
        'calendar_monthly_week',
        'calendar_showbirthdays',
        'calendar_weekly_day',
        'calendar_yearly',
        'CALENDAR'
    ),
    'getinfo' => array(
        'calendar_showevents',
        'calendar_showbirthdays',
        'calendar_showeventsbit',
        'calendar_showeventsbit_customfield'
    ),
    'edit' => array(
        'calendar_edit',
        'calendar_edit_customfield',
        'calendar_edit_recurrence',
        'userfield_select_option'
    ),
    'manage' => array(
        'calendar_edit',
        'calendar_manage'
    ),
    'viewreminder' => array(
        'CALENDAR_REMINDER',
        'calendar_reminder_eventbit',
        'USERCP_SHELL',
        'forumdisplay_sortarrow',
        'usercp_nav_folderbit',
    ),
    'addreminder' => array(
        'USERCP_SHELL',
        'calendar_reminder_choosetype',
        'usercp_nav_folderbit',
    ),
);

$actiontemplates['getday'] =& $actiontemplates['getinfo'];
$actiontemplates['add'] =& $actiontemplates['edit'];
$actiontemplates['displaymonth'] =& $actiontemplates['displayweek'];
$actiontemplates['none'] =& $actiontemplates['displayweek'];

// ########################## REQUIRE BACK-END ############################
require_once('./global.php');
require_once(DIR . '/includes/functions_calendar.php');


// ########################## AJAX RECIVER ############################

function My_AJAX_Reciever()
{
        if (My_AJAX_Object.handler.readyState == 4 && My_AJAX_Object.handler.status == 200 && My_AJAX_Object.handler.responseText)
        {
               alert('Data recieved successfully\n\n' + My_AJAX_Object.handler.responseText);
        }

}


// ########################## AJAX SETUP ############################

My_AJAX_Object = new vB_AJAX_Handler(true);


My_AJAX_Object.onreadystatechange(My_AJAX_Reciever);



// ########################################################################
// ######################### START MAIN SCRIPT ############################
// ########################################################################

$serveroffset = date('Z', TIMENOW) / 3600;

$idname = $vbphrase['event'];

$vbulletin->input->clean_array_gpc('r', array(
    'calendarid' => TYPE_UINT,
    'eventid'    => TYPE_UINT,
    'holidayid'  => TYPE_UINT,
    'week'       => TYPE_UINT,
    'month'      => TYPE_UINT,
    'year'       => TYPE_UINT,
    'sb'         => TYPE_UINT,
));

($hook = vBulletinHook::fetch_hook('calendar_start')) ? eval($hook) : false;


if ($_POST['do'] == 'ajax') 
{ 
     $jump = $_POST['mydata']; 

    // Calling my PHP function Here 

       $Retval =  trap_calandar_jump($jump);

     // After doing everything in my function - HOW DO I GET BACK TO THE SENDER IN THE JAVASCRPT FUNCTION process_selected

   
   return  $Retval;

}

If I have posted to much vbulletin please edited it down for me so that I have a good idea if i am doing good so far and if i run into any problems you will be able to help me through the problem. So I have posted the above incase placement is important if not then let me know that also? THANKS.

Next is my javascript function modifaction to go with the dropdown.

PHP Code:



<script type="text/javascript"> function process_selected(form) {
             
        var msgstr = " - " + "Regular Meetings" + " !";
                    
             alert('This is working' + msgstr);

        var myme = form["me"].value;
        var myc =  form["c"].value;
        var mydo =  form["do"].value;
        var mys =  form["s"].value;



             alert('This is working !' + " - " + myme + " - " + myc);
            
             mydata = PHP.urlencode(myc);


             My_AJAX_Object.send('calendar.php', 'do=ajax&mydata=text');


             
             form.submit();

}
</script> 


Please look at the passing of the data did i get the assignemnts right in javascript and then paassing the stuff through my ajax sender.


Now my PHP function to handle the PHP Logic

PHP Code:


function trap_calandar_jump($jump)

{
            switch ($jump) {
    case 1:
        // Logic here  Jump drop down 1
        break;

    case 2:
        // Logic here Jump drop down 2
        break;

    case 3:
        // Logic here Jump drop down 3
        break;

}//switch
 return $something;

} 


AFTER LOOKING AT ALL THE ABOVE

QUESTION 1 - DID I SET EVERYTHING UP RIGHT AND MAKE THE CORRECT CALLS AND DID NOT MIX UP MY VARIABLES?

QUESTION 2 HOW DO I GET BACK TO THE SENDER IN THE JAVASCRPT FUNCTION process_selected

I HOPE I HAVE THIS ALL CORRECT ABOVE?

This the error message when I run my calendar.php

Fatal error: Class 'vB_AJAX_Handler' not found in C:\Inetpub\vhosts\burningtaper.org\httpdocs\forums \calendar.php on line 131


At the line 131 number is the following line.

PHP Code:


       My_AJAX_Object = new vB_AJAX_Handler(true); 


What is missing ?
