Typecho主题评论原生表情实现方法

表情放在主题目录img/smilies下。
首先添加functions.php自定义评论回调部分的代码，自定义评论回调部分可以参考Typecho更简单的解决Gravatar被墙提到的方法。
然后再在functions.php将回调函数的content(); ?>修改为content); ?>
接着在functions.php下面加入代码：
/** 解析表情 */
function convertSmilies($widget)
{
$smiliesTrans = array(
':?:' => 'icon_question.gif',
':razz:' => 'icon_razz.gif',
':sad:' => 'icon_sad.gif',
':evil:' => 'icon_evil.gif',
':!:' => 'icon_exclaim.gif',
':smile:' => 'icon_smile.gif',
':oops:' => 'icon_redface.gif',
':grin:' => 'icon_biggrin.gif',
':eek:' => 'icon_surprised.gif',
':shock:' => 'icon_eek.gif',
':???:' => 'icon_confused.gif',
':cool:' => 'icon_cool.gif',
':lol:' => 'icon_lol.gif',
':mad:' => 'icon_mad.gif',
':twisted:' => 'icon_twisted.gif',
':roll:' => 'icon_rolleyes.gif',
':wink:' => 'icon_wink.gif',
':idea:' => 'icon_idea.gif',
':arrow:' => 'icon_arrow.gif',
':neutral:' => 'icon_neutral.gif',
':cry:' => 'icon_cry.gif',
':mrgreen:' => 'icon_mrgreen.gif',
'8-)' => 'icon_cool.gif',
'8-O' => 'icon_eek.gif',
':-(' => 'icon_sad.gif',
':-)' => 'icon_smile.gif',
':-?' => 'icon_confused.gif',
':-D' => 'icon_biggrin.gif',
':-P' => 'icon_razz.gif',
':-o' => 'icon_surprised.gif',
':-x' => 'icon_mad.gif',
':-|' => 'icon_neutral.gif',
';-)' => 'icon_wink.gif',
'8)' => 'icon_cool.gif',
'8O' => 'icon_eek.gif',
':(' => 'icon_sad.gif',
':)' => 'icon_smile.gif',
':?' => 'icon_confused.gif',
':D' => 'icon_biggrin.gif',
':P' => 'icon_razz.gif',
':o' => 'icon_surprised.gif',
':x' => 'icon_mad.gif',
':|' => 'icon_neutral.gif',
';)' => 'icon_wink.gif',
);
$imgUrl = Typecho_Widget::widget('Widget_Options')->themeUrl . '/img/smilies/';
foreach($smiliesTrans as $smiley => $img) {
$smiliesTag[] = $smiley;
$smiliesReplace[] = "
";
}
$output = '';
$textArr = preg_split("/(<.*>)/U", $widget, -1, PREG_SPLIT_DELIM_CAPTURE);
$stop = count($textArr);
for ($i = 0; $i < $stop; $i++) {
$content = $textArr[$i];
if ((strlen($content) > 0) && ('<' != $content{0})) {
$content = str_replace($smiliesTag, $smiliesReplace, $content);
}
$output .= $content;
}
$output = preg_replace('/\[img=?\]*(.*?)(\[\/img)?\]/e', '""', $output);
echo $output;
}
接下来，在主题目录新建inc目录，然后新建smiley.php文件内容如下：
options->themeUrl . '/img/smilies/'; ?>
icon_question.gif" alt="" class="smiley" />
icon_razz.gif" alt="" class="smiley" />
icon_sad.gif" alt="" class="smiley" />
icon_evil.gif" alt="" class="smiley" />
icon_exclaim.gif" alt="" class="smiley" />
icon_smile.gif" alt="" class="smiley" />
icon_redface.gif" alt="" class="smiley" />
icon_biggrin.gif" alt="" class="smiley" />
icon_surprised.gif" alt="" class="smiley" />
icon_eek.gif" alt="" class="smiley" />
icon_confused.gif" alt="" class="smiley" />
icon_cool.gif" alt="" class="smiley" />
icon_lol.gif" alt="" class="smiley" />
icon_mad.gif" alt="" class="smiley" />
icon_twisted.gif" alt="" class="smiley" />
icon_rolleyes.gif" alt="" class="smiley" />
icon_wink.gif" alt="" class="smiley" />
icon_idea.gif" alt="" class="smiley" />
icon_arrow.gif" alt="" class="smiley" />
icon_neutral.gif" alt="" class="smiley" />
icon_cry.gif" alt="" class="smiley" />
icon_mrgreen.gif" alt="" class="smiley" />
然后编辑comments.php文件，在评论框
