WordPress自定义表情及其路径

2016/8/6 14:07:11 Skills 3 Comments 4,073 Views

不得不说，一篇好的文章，中间插入一些表情，能为文章增色不少。昨天看到朋友的博文中，有表情图片，我当时就愣了一下，对啊，我的博客写文章时还没有表情呢。于是，今天就实战操作一把。网上有许多在WordPress中插入表情的文章，作为大自然的搬运工，我就在这记录一下。

1. 将表情文件上传到主题文件夹下的images/smilies文件夹中（注：此处的路径需和下方的一致）

2.将下面代码保存到smiley.php文件中，然后上传文件到主题文件夹中。

<script type="text/javascript" language="javascript">
 /* <![CDATA[ */
   function grin(tag) {
   var myField;
   tag = ' ' + tag + ' ';
   if (document.getElementById('comment') && document.getElementById('comment').type == 'textarea') {
     myField = document.getElementById('comment');
   } else {
     return false;
   }
   if (document.selection) {
     myField.focus();
     sel = document.selection.createRange();
     sel.text = tag;
     myField.focus();
   }else if (myField.selectionStart || myField.selectionStart == '0') {
     var startPos = myField.selectionStart;
     var endPos = myField.selectionEnd;
     var cursorPos = endPos;
     myField.value = myField.value.substring(0, startPos)
                   + tag
                   + myField.value.substring(endPos, myField.value.length);
     cursorPos += tag.length;
     myField.focus();
     myField.selectionStart = cursorPos;
     myField.selectionEnd = cursorPos;
   }else {
     myField.value += tag;
     myField.focus();
   }
 }
 /* ]]> */
 </script>
 <a href="javascript:grin(\':razz:\')"><img src="'.get_bloginfo("template_url").'/images/smilies/icon_razz.gif" alt="" class="size-smiley"/></a>
 <a href="javascript:grin(\':sad:\')"><img src="'.get_bloginfo("template_url").'/images/smilies/icon_sad.gif" alt="" class="size-smiley"/></a>
 <a href="javascript:grin(\':evil:\')"><img src="'.get_bloginfo("template_url").'/images/smilies/icon_evil.gif" alt="" class="size-smiley"/></a>
                                      ...

/* <![CDATA[ */

function grin(tag) {

var myField;

tag = ' ' + tag + ' ';

if (document.getElementById('comment') && document.getElementById('comment').type == 'textarea') {

myField = document.getElementById('comment');

} else {

return false;

}

if (document.selection) {

myField.focus();

sel = document.selection.createRange();

sel.text = tag;

myField.focus();

}else if (myField.selectionStart || myField.selectionStart == '0') {

var startPos = myField.selectionStart;

var endPos = myField.selectionEnd;

var cursorPos = endPos;

myField.value = myField.value.substring(0, startPos)

+ tag

+ myField.value.substring(endPos, myField.value.length);

cursorPos += tag.length;

myField.focus();

myField.selectionStart = cursorPos;

myField.selectionEnd = cursorPos;

}else {

myField.value += tag;

myField.focus();

}

/* ]]> */

</script>

...

3.将表情添加到评论区：

找到主题文件下的comments.php,修改其中

&lt;!--&lt;span data-type="comment-insert-smilie" class="muted comt-smilie"&gt;&lt;i class="icon-thumbs-up icon12"&gt;&lt;/i&gt; 表情&lt;/span&gt;--&gt;
替换为：
&lt;?php include(TEMPLATEPATH . '/smiley.php');?&gt;

替换为：

<?php include(TEMPLATEPATH . '/smiley.php');?>

4.将表情添加到文章中

将下列代码添加到function.php中

//输出WordPress表情
function fa_get_wpsmiliestrans(){
  global $wpsmiliestrans;
  $wpsmilies = array_unique($wpsmiliestrans);
  foreach($wpsmilies as $alt =&gt; $src_path){
    $output .= '&lt;a class="add-smily" data-smilies="'.$alt.'"&gt;&lt;img class="wp-smiley" src="'.get_bloginfo('template_directory').'/images/smilies/'.rtrim($src_path, "gif").'gif" /&gt;&lt;/a&gt;';
  }
  return $output;
}
add_action('media_buttons_context', 'fa_smilies_custom_button');
function fa_smilies_custom_button($context) {
  $context .= '&lt;style&gt;.smilies-wrap{background:#fff;border: 1px solid #ccc;box-shadow: 2px 2px 3px rgba(0, 0, 0, 0.24);padding: 10px;position: absolute;top: 60px;width: 380px;display:none}.smilies-wrap img{height:24px;width:24px;cursor:pointer;margin-bottom:5px} .is-active.smilies-wrap{display:block}&lt;/style&gt;&lt;a id="insert-media-button" style="position:relative" class="button insert-smilies add_smilies" title="添加表情" data-editor="content" href="javascript:;"&gt;
  添加表情
  &lt;/a&gt;&lt;div class="smilies-wrap"&gt;'. fa_get_wpsmiliestrans() .'&lt;/div&gt;&lt;script&gt;jQuery(document).ready(function(){jQuery(document).on("click", ".insert-smilies",function() { if(jQuery(".smilies-wrap").hasClass("is-active")){jQuery(".smilies-wrap").removeClass("is-active");}else{jQuery(".smilies-wrap").addClass("is-active");}});jQuery(document).on("click", ".add-smily",function() { send_to_editor(" " + jQuery(this).data("smilies") + " ");jQuery(".smilies-wrap").removeClass("is-active");return false;});});&lt;/script&gt;';
  return $context;
}

//输出WordPress表情

function fa_get_wpsmiliestrans(){

global $wpsmiliestrans;

$wpsmilies = array_unique($wpsmiliestrans);

foreach($wpsmilies as $alt => $src_path){

$output .= '<a class="add-smily" data-smilies="'.$alt.'"><img class="wp-smiley" src="'.get_bloginfo('template_directory').'/images/smilies/'.rtrim($src_path, "gif").'gif" /></a>';

}

return $output;

}

add_action('media_buttons_context', 'fa_smilies_custom_button');

function fa_smilies_custom_button($context) {

$context .= '<style>.smilies-wrap{background:#fff;border: 1px solid #ccc;box-shadow: 2px 2px 3px rgba(0, 0, 0, 0.24);padding: 10px;position: absolute;top: 60px;width: 380px;display:none}.smilies-wrap img{height:24px;width:24px;cursor:pointer;margin-bottom:5px} .is-active.smilies-wrap{display:block}</style><a id="insert-media-button" style="position:relative" class="button insert-smilies add_smilies" title="添加表情" data-editor="content" href="javascript:;">

添加表情

</a><div class="smilies-wrap">'. fa_get_wpsmiliestrans() .'</div><script>jQuery(document).ready(function(){jQuery(document).on("click", ".insert-smilies",function() { if(jQuery(".smilies-wrap").hasClass("is-active")){jQuery(".smilies-wrap").removeClass("is-active");}else{jQuery(".smilies-wrap").addClass("is-active");}});jQuery(document).on("click", ".add-smily",function() { send_to_editor(" " + jQuery(this).data("smilies") + " ");jQuery(".smilies-wrap").removeClass("is-active");return false;});});</script>';

return $context;

}

注意：上面代码设置的表情路径为主题文件夹/images/smilies，所以请一定确认目录名字是否一样，如果不一样请根据需要修改。

5.完成上述操作后，在发布文章时，就会看到添加媒体选项右侧多了一个添加表情，点击一下就可以看到酷酷的qq表情啦，如下图： wp-emoji1

但是注意：第4步的代码功能还是有缺陷的，比如你会发现你现在发布表情时表情会单独占用一行，而且表情看起来有时候很小而不是原来的大小，这个肯定不行三，所以还要看第6步。

6.在style.css中添加下面代码

.wp-smiley{
    display:inline-block !inportant;    /*为了让表情不会独占一行*/
    height:24px !improtant;    /*为了让表情不和默认CSS冲突，让表情显示的大点*/
    max-height:24px !important;
}
