javascript - 如何在 WordPress 中实现 AJAX 评论

Question

我正尝试使用本教程在 WordPress 中“ajaxify”评论 Ajaxify WordPress Comments

这是我的 PHP 处理程序:

function ajaxify_comments( $comment_ID, $comment_status ){
    if( ! empty( $_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'] );
                wp_notify_postauthor( $comment_ID, $commentdata['comment_type'] );
                break;
            default:
                echo "error";
        }
        exit;
    }
}
add_action( 'comment_post', 'ajaxify_comments', 20, 2 );

这是我的脚本:

jQuery('document').ready(function($){
    var commentform=$('#commentform'); // find the comment form
    commentform.prepend('<div id="comment-status" ></div>'); // add info panel before the form to provide feedback or errors
    var statusdiv=$('#comment-status'); // define the infopanel

    commentform.submit(function(){
        //serialize and store form data in a variable
        var formdata=commentform.serialize();
        //Add a status message
        statusdiv.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){
                statusdiv.html('<p class="ajax-error" >You might have left one of the fields blank, or be posting too quickly</p>');
                                },
            success: function(data, textStatus){
                if(data=="success")
                    statusdiv.html('<p class="ajax-success" >Thanks for your comment. We appreciate your response.</p>');
                else
                    statusdiv.html('<p class="ajax-error" >Please wait a while before posting your next comment</p>');
                    commentform.find('textarea[name=comment]').val('');
                                }
                });
                return false;
        });
});

每次我发表评论时，我都会收到:“请稍等片刻，然后再发表您的下一条评论”。希望有人能告诉我我做错了什么？

试试这个:

jQuery('document').ready(function($){
    var commentform=$('#commentform'); // find the comment form
    commentform.prepend('<div id="comment-status" ></div>'); // add info panel before the form to provide feedback or errors
    var statusdiv=$('#comment-status'); // define the infopanel

    commentform.submit(function(){
        //serialize and store form data in a variable
        var formdata=commentform.serialize();
        //Add a status message
        statusdiv.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)
                {
                    statusdiv.html('<p class="ajax-error" >You might have left one of the fields blank, or be posting too quickly</p>');
                },
            success: function(data, textStatus){
                if(data == "success" || textStatus == "success"){
                    statusdiv.html('<p class="ajax-success" >Thanks for your comment. We appreciate your response.</p>');
                }else{
                    statusdiv.html('<p class="ajax-error" >Please wait a while before posting your next comment</p>');
                    commentform.find('textarea[name=comment]').val('');
                }
            }
        });
        return false;
    });
});
