Question

I try to create a plugin allow users to add new post, edit post, and delete post from the front end.
Now when the user try to edit the post instead of updating the the same post the plugin create new page ! in pending status.
Can anyone help me please?
This is the code of edit post class:
<?php
/**
* Edit Post form class
*
* #author Engr.MTH
* #package MOSTASHAROON Frontend Form
*/
class MOSFF_Edit_Post {
function __construct() {
add_shortcode( 'mosff_editpost', array($this, 'shortcode') );
}
/**
* Handles the edit post shortcode
*
*
*/
function shortcode() {
$query = new WP_Query(array('post_type' => 'post', 'posts_per_page' =>'-1', 'post_status' => array('publish', 'pending', 'draft', 'private', 'trash') ) );
if ($query->have_posts()) : while ($query->have_posts()) : $query->the_post();global $post;
if(isset($_GET['post'])) {
if($_GET['post'] == $post->ID)
{
$current_post = $post->ID;
$title = get_the_title();
$content = get_the_content();
$custom_one = get_post_meta($current_post, 'vsip_custom_one', true);
$custom_two = get_post_meta($current_post, 'vsip_custom_two', true);
}
}
endwhile; endif;
wp_reset_query();
global $current_post;
$postTitleError = '';
if(isset($_POST['submitted']) && isset($_POST['post_nonce_field']) && wp_verify_nonce($_POST['post_nonce_field'], 'post_nonce')) {
if(trim($_POST['postTitle']) === '') {
$postTitleError = 'Please enter a title.';
$hasError = true;
} else {
$postTitle = trim($_POST['postTitle']);
}
$post_information = array(
'ID' => $current_post,
'post_title' => esc_attr(strip_tags($_POST['postTitle'])),
'post_content' => esc_attr(strip_tags($_POST['postContent'])),
'post-type' => 'post',
'post_status' => 'pending'
);
$post_id = wp_update_post($post_information);
if($post_id)
{
// Update Custom Meta
update_post_meta($post_id, 'vsip_custom_one', esc_attr(strip_tags($_POST['customMetaOne'])));
update_post_meta($post_id, 'vsip_custom_two', esc_attr(strip_tags($_POST['customMetaTwo'])));
wp_redirect( home_url() ); exit;
}
}
?>

Answer 1

I found the answer, just I remove this line:
global $current_post;

Answer 2

I think you can do this by getting the post id and query it to get all the fields of the particular and edit it through a form and post it again.
