I am using wordpress 3.8. I am using comment_form();
I need to display a success message
on successfully posted comment on blog. How to do this?
Without Ajax or plugins. Add to function.php:
add_action( 'set_comment_cookies', function( $comment, $user ) {
setcookie( 'ta_comment_wait_approval', '1' );
}, 10, 2 );
add_action( 'init', function() {
if( $_COOKIE['ta_comment_wait_approval'] === '1' ) {
setcookie( 'ta_comment_wait_approval', null, time() - 3600, '/' );
add_action( 'comment_form_before', function() {
echo "<p id='wait_approval' style='padding-top: 40px;'><strong>Your comment has been sent successfully.</strong></p>";
});
}
});
add_filter( 'comment_post_redirect', function( $location, $comment ) {
$location = get_permalink( $comment->comment_post_ID ) . '#wait_approval';
return $location;
}, 10, 2 );
Try this: http://wordpress.org/plugins/wp-ajaxify-comments/
or (manually)
Add the following lines of code to your theme’s functions.php file
add_action('init', 'wdp_ajaxcomments_load_js', 10);
function wdp_ajaxcomments_load_js(){
wp_enqueue_script('ajaxValidate', get_stylesheet_directory_uri().'/wdp-ajaxed-comments/js/jquery.validate.min.js', array('jquery'), '1.5.5');
wp_enqueue_script('ajaxcomments', get_stylesheet_directory_uri().'/wdp-ajaxed-comments/js/ajax-comments.js', array('jquery', 'ajaxValidate'), '1.1');
}
add_action('comment_post', 'wdp_ajaxcomments_stop_for_ajax',20, 2);
function wdp_ajaxcomments_stop_for_ajax($comment_ID, $comment_status){
if(!emptyempty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest'){
//If AJAX Request Then
switch($comment_status){
case '0':
//notify moderator of unapproved comment
wp_notify_moderator($comment_ID);
case '1': //Approved comment
echo "success";
$commentdata=&get_comment($comment_ID, ARRAY_A);
$post=&get_post($commentdata['comment_post_ID']); //Notify post author of comment
if ( get_option('comments_notify') && $commentdata['comment_approved'] && $post->post_author != $commentdata['user_ID'] )
wp_notify_postauthor($comment_ID, $commentdata['comment_type']);
break;
default:
echo "error";
}
exit;
}
}
You will need to add two JavaScript files jquery.validate.min.js and ajax-comments.js in the js directory of your theme. http://bassistance.de/jquery-plugins/jquery-plugin-validation/
and the ajax-comments.js is:
jQuery('document').ready(function($){
var commentform=$('form[action$=wp-comments-post.php]');
commentform.prepend('<div id="wdpajax-info" ></div>');
var infodiv=$('#wdpajax-info');
commentform.validate({
submitHandler: function(form){
//serialize and store form data in a variable
var formdata=commentform.serialize();
//Add a status message
infodiv.html('<p>Processing...</p>');
//Extract action URL from commentform
var formurl=commentform.attr('action');
//Post Form with data
$.ajax({
type: 'post',
url: formurl,
data: formdata,
error: function(XMLHttpRequest, textStatus, errorThrown){
infodiv.html('<p class="wdpajax-error" >You might have left one of the fields blank.</p>');
},
success: function(data, textStatus){
if(data=="success")
infodiv.html('<p class="wdpajax-success" >Thanks for your comment. We appreciate your response.</p>');
else
infodiv.html('<p class="wdpajax-error" >Error in processing your form.</p>');
commentform.find('textarea[name=comment]').val('');
}
});
}
});
});
Customize the style of messages
.wdpajax-error{
border:1px solid #f9d9c9;
padding:5px;
color:#ff3311;
}
.wdpajax-success{
border:1px solid #339933;
padding:5px;
color:#339933;
}
label.error{
float:none !important;
padding-left:5px;
color:#ff3311;
}
Open your theme’s comments.php and add some CSS classes to comment form input fields as described: To comment author name input, add class="required" To comment author email input, add class="required email" To comment author URL input, add class="url" To the comment textarea, add class="required"
