WordPress短代码添加闪光按钮

效果图：在这里说下，由于截图，无法生成闪光，大家自行测试。

将以下代码添加到style.css文件里：

[class*=sgbtn]{display:inline-block;text-indent:0;position:relative;color:#fff;padding:0 10px 0 10px;min-width:160px;height:38px;line-height:38px;opacity:.8;text-align:center;font-family:Ubuntu,sans-serif;font-size:15px;text-decoration:none;border-radius:2px;overflow:hidden;-webkit-transition:all .15s ease-in;transition:all .15s ease-in}[class*=sgbtn]:before{content:'';position:absolute;background:#fff;width:25px;height:50px;top:0;left:-45px;opacity:.3;-webkit-transition:all .25s ease-out;transition:all .25s ease-out;-webkit-transform:skewX(-25deg);transform:skewX(-25deg)}[class*=sgbtn]:hover{opacity:.65}[class*=sgbtn]:hover:before{width:45px;left:205px}.sgbtn_blue{background:#1cb2f5}.sgbtn_red{background:#C00}.sgbtn_orange{background:#F90}.sgbtn_lv{background:#096}a[class*=sgbtn]{color:#fff}a[class*=sgbtn]:hover{color:#fff}

将以下代码添加到functions.php里：

/*添加蓝色闪光按钮*/
function sg_blue($atts, $content = null) {
    extract(shortcode_atts(array(
        "href" => 'http://'
    ) , $atts));
    return '<a class="sgbtn_blue" href="' . $href . '" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  target="_blank" rel="nofollow">' . $content . '</a>';
}
add_shortcode('sgbtn_blue', 'sg_blue');
/*添加红色闪光按钮*/
function sg_red($atts, $content = null) {
    extract(shortcode_atts(array(
        "href" => 'http://'
    ) , $atts));
    return '<a class="sgbtn_red" href="' . $href . '" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  target="_blank" rel="nofollow">' . $content . '</a>';
}
add_shortcode('sgbtn_red', 'sg_red');
/*添加橙色闪光按钮*/
function sg_orange($atts, $content = null) {
    extract(shortcode_atts(array(
        "href" => 'http://'
    ) , $atts));
    return '<a class="sgbtn_orange" href="' . $href . '" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  target="_blank" rel="nofollow">' . $content . '</a>';
}
add_shortcode('sgbtn_orange', 'sg_orange');
/*添加绿色闪光按钮*/
function sg_lv($atts, $content = null) {
    extract(shortcode_atts(array(
        "href" => 'http://'
    ) , $atts));
    return '<a class="sgbtn_lv" href="' . $href . '" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  target="_blank" rel="nofollow">' . $content . '</a>';
}
add_shortcode('sgbtn_lv', 'sg_lv');
