1.以下代码放入functions.php中

将短代码快捷键插入菜单中:

function appthemes_add_quicktags() {
?> 
<script type="text/javascript"> 
QTags.addButton( 'd2', '密码', '[secret key="设置密码"]加密内容[/secret]' );
</script>
<?php
}
add_action('admin_print_footer_scripts', 'appthemes_add_quicktags' );

加密功能:

function e_secret($atts, $content=null){
    extract(shortcode_atts(array('key'=>null), $atts));
    if(isset($_POST['e_secret_key']) && $_POST['e_secret_key']==$key){
        return '
<div class="e-secret">'.$content.'</div>
';
    }
    else{
        return '
<form class="e-secret" action="'.get_permalink().'" method="post" name="e-secret"><label>输入密码查看加密内容:</label><input type="password" name="e_secret_key" class="euc-y-i" maxlength="50"><input type="submit" class="euc-y-s" value="确定">
<div class="euc-clear"></div>
</form>
';
    }
}
add_shortcode('secret','e_secret');

CSS样式放入style.css中

/*e-secret*/
.e-secret {
    margin: 20px 0;
    padding: 20px;
    background: #f8f8f8;
    overflow: auto;
}
.e-secret input.euc-y-i[type="password"] {
    float: left;
    background: #fff;
    width: 100%;
    line-height: 36px;
    margin-top: 5px;
    border-radius: 3px;
}
.e-secret input.euc-y-s[type="submit"] {

    margin-top: -47px;
    width: 30%;
