WordPress评论框添加简单文本编辑器和弹出表情框

功能和效果如文后评论框,包括:粗体、斜体、下划线、删除线、链接、图片、代码、引用、隐藏、表情,需要更多功能的可以尝试使用JS Quicktags或者在评论框加载TinyMCE Advanced编辑器。

一、functions.php添加以下代码:

// -- START ----------------------------------------
function wp_smilies() {
    global $wpsmiliestrans;
    if ( !get_option('use_smilies') or (empty($wpsmiliestrans))) return;
    $smilies = array_unique($wpsmiliestrans);
    $link='';
    foreach ($smilies as $key => $smile) {
        $file = get_bloginfo('wpurl').'/wp-includes/images/smilies/'.$smile;
        $value = " ".$key." ";
        $img = "<img src=\"{$file}\" alt=\"{$smile}\" />";
        $imglink = htmlspecialchars($img);
        $link .= "<span><a href=\"#commentform\" title=\"{$smile}\" onclick=\"document.getElementById('comment').value += '{$value}'\">{$img}</a></span>";
    }
    echo '<div>
<span><a href="javascript:SIMPALED.Editor.strong()" title="粗体">粗体</a></span>
<span><a href="javascript:SIMPALED.Editor.em()" title="斜体">斜体</a></span>
<span><a href="javascript:SIMPALED.Editor.underline()" title="下划线">下划线</a></span>
<span><a href="javascript:SIMPALED.Editor.del()" title="删除线">删除线</a></span>
<span><a href="javascript:SIMPALED.Editor.ahref()" title="链接">链接</a></span>
<span><a href="javascript:SIMPALED.Editor.img()" title="图片">图片</a></span>
<span><a href="javascript:SIMPALED.Editor.code()" title="代码">代码</a></span>
<span><a href="javascript:SIMPALED.Editor.quote()" title="引用">引用</a></span>
<span><a href="javascript:SIMPALED.Editor.private()" title="隐藏">隐藏</a></span>
<span><a href="javascript:SIMPALED.Editor.smilies()" title="表情">表情</a></span>
<div id="smilies-container"><div>'.$link.'</div></div></div>';
}

if (is_user_logged_in()) {
    add_filter('comment_form_logged_in_after', 'wp_smilies');
}
else {
    add_filter( 'comment_form_after_fields', 'wp_smilies');
}

function private_content($atts, $content = null)
{ if (current_user_can('create_users'))
return '' . $content . ''; return '***隐藏内容仅管理员可见***'; }
add_shortcode('private', 'private_content');
add_filter('comment_text', 'do_shortcode'); /* 添加隐藏短代码*/
// -- END ----------------------------------------

二、然后加载以下JS即可(表情框需要jQuery):

/* smilies toggle
-----------------------------------------------*/
$(function() {
    $("a.et_smilies").click(function() {
        $('#smilies-container').toggle(function() {
            $(document).click(function(event) {
                if (!($(event.target).is('#smilies-container') || $(event.target).parents('#smilies-container').length || $(event.target).is('a.et_smilies'))) {
                    $('#smilies-container').hide(200);
                }
            });
        });
    });
});

/* comment editor
-----------------------------------------------*/
$(function() {
    function addEditor(a, b, c) {
        if (document.selection) {
            a.focus();
            sel = document.selection.createRange();
            c ? sel.text = b + sel.text + c: sel.text = b;
            a.focus()
        } else if (a.selectionStart || a.selectionStart == '0') {
            var d = a.selectionStart;
            var e = a.selectionEnd;
            var f = e;
            c ? a.value = a.value.substring(0, d) + b + a.value.substring(d, e) + c + a.value.substring(e, a.value.length) : a.value = a.value.substring(0, d) + b + a.value.substring(e, a.value.length);
            c ? f += b.length + c.length: f += b.length - e + d;
            if (d == e && c) f -= c.length;
            a.focus();
            a.selectionStart = f;
            a.selectionEnd = f
        } else {
            a.value += b + c;
            a.focus()
        }
    }
    var g = document.getElementById('comment') || 0;
    var h = {
        strong: function() {
            addEditor(g, '<strong>', '</strong>')
        },
        em: function() {
            addEditor(g, '<em>', '</em>')
        },
        del: function() {
            addEditor(g, '<del>', '</del>')
        },
        underline: function() {
            addEditor(g, '<u>', '</u>')
        },
        quote: function() {
            addEditor(g, '<blockquote>', '</blockquote>')
        },
        private: function() {
            addEditor(g, '***隐藏内容仅管理员可见***')
        },
        ahref: function() {
            var a = prompt('请输入链接地址', 'http://');
            var b = prompt('请输入链接描述','');
            if (a) {
                addEditor(g, '<a target="_blank" href=”' + a + '" rel="external”>' + b + '</a>','')
            }
        },
        img: function() {
            var a = prompt('请输入图片地址', 'http://');
            if (a) {
                addEditor(g, '<img src="' + a + '" alt="" />','')
            }
        },
        code: function() {
            addEditor(g, '<code>', '</code>')
        }
    };
    window['SIMPALED'] = {};
    window['SIMPALED']['Editor'] = h
});

三、CSS部分(仅供参考):
