Adding extra functionality to a plugin WordPress

  • SOLVED

Hello,

I would like to add functionality to an Event Manager Plugin.
Adding an extra checkbox for "Past" events.

For you to understand, I made a screenshot of the admin and front end.


Here is the code for the plugin

<?php
/*
Plugin Name: Event Manager
Description: c-om-p-o-s-i-t-e
Version: 1.0
*/

function pps_video_seo_metabox() {
global $post;

$ppsupload1 = get_post_meta( $post->ID, 'ppsupload1', true );
$ppsupload2 = get_post_meta( $post->ID, 'ppsupload2', true );
$ppsupload3 = get_post_meta( $post->ID, 'ppsupload3', true );
$ppsevent1 = get_post_meta( $post->ID, 'ppsevent1', true );
$ppsevent2 = get_post_meta( $post->ID, 'ppsevent2', true );
$ppstitle = get_post_meta( $post->ID, 'ppstitle', true );
$posttype = get_post_meta( $post->ID, 'posttype', true );


?>

<script>

jQuery(document).ready(function($) {

var formfield = null;

$('#upload_logo_button1').click(function() {

$('html').addClass('Image');

formfield = $(this).prev('input').attr('name');
formfield_id = $(this).prev('input').attr('id');

tb_show( '', 'media-upload.php?type=image&TB_iframe=true' );

window.original_send_to_editor = window.send_to_editor;
window.send_to_editor = function( html ) {
var fileurl;

if(formfield != null) {
fileurl = $( 'img', html).attr('src');

$('#ppsupload1').val(fileurl);

tb_remove();

$('html').removeClass('Image');
formfield = null;
} else {
window.original_send_to_editor(html);
}
};
return false;

});

$('#upload_logo_button2').click(function() {

$('html').addClass('Image');

formfield = $(this).prev('input').attr('name');
formfield_id = $(this).prev('input').attr('id');

tb_show( '', 'media-upload.php?type=image&TB_iframe=true' );

window.original_send_to_editor = window.send_to_editor;
window.send_to_editor = function( html ) {
var fileurl;

if(formfield != null) {
fileurl = $( 'img', html).attr('src');

tb_remove();

<li class="upcomingclass">

<span class="dateblk">30/01/2014 > 01/03/2014</span>

<br>

<a href="http://www.c-o-m-p-o-s-i-t-e.com/assunta-ruocco-3/">

<h1 class="entry-title"> Assunta Ruocco - A Record of Unaddressed Activity</h1>

</a>

</li>


And here the colors for the events :

Upcoming : #999
Current : #000
Past : #999


Arnav Joy comments:

<li class="upcomingclass">



<span class="dateblk">30/01/2014 > 01/03/2014</span>



<br>







<h1 class="entry-title"> Assunta Ruocco - A Record of Unaddressed Activity</h1>
