简介

我们把ripro主题包美化的单独美化分开来，方便大家自行选择的美化。今天做的是单独增加点赞功能，纯代码无需插件。。。

代码部署

找到 function.php

ripro主题目录/wp-content/themes/ripro

ripro子主题目录/wp-content/themes/。。。。-child

添加如下代码[wxshow]

/*加一个点赞功能*/
    add_action('wp_ajax_nopriv_bigfa_like', 'bigfa_like');

    add_action('wp_ajax_bigfa_like', 'bigfa_like');

    function bigfa_like(){

        global $wpdb,$post;

        $id = $_POST["um_id"];

        $action = $_POST["um_action"];

        if ( $action == 'ding'){

        $bigfa_raters = get_post_meta($id,'bigfa_ding',true);

        $expire = time() + 99999999;

        $domain = ($_SERVER['HTTP_HOST'] != 'localhost') ? $_SERVER['HTTP_HOST'] : false; // make cookies work with localhost

        setcookie('bigfa_ding_'.$id,$id,$expire,'/',$domain,false);

        if (!$bigfa_raters || !is_numeric($bigfa_raters)) {

            update_post_meta($id, 'bigfa_ding', 1);

        } 

        else {

                update_post_meta($id, 'bigfa_ding', ($bigfa_raters + 1));

            }

     

        echo get_post_meta($id,'bigfa_ding',true);

     

        } 

     

        die;

    }

[/wxshow]

ripro主题目录/wp-content/themes/ripro /footer.php

ripro子主题目录/wp-content/themes/。。。。-child /footer.php

添加如下代码

 <!--加一个点赞的功能-->
     <script type="text/javascript">

    $.fn.postLike = function() {

        if ($(this).hasClass('done')) {

            return false;

        } else {

            $(this).addClass('done');

            var id = $(this).data("id"),

            action = $(this).data('action'),

            rateHolder = $(this).children('.count');

            var ajax_data = {

                action: "bigfa_like",

                um_id: id,

                um_action: action

            };

            $.post("/wp-admin/admin-ajax.php", ajax_data,

            function(data) {

                $(rateHolder).html(data);

            });

            return false;

        }

    };

    $(document).on("click", ".favorite",

    function() {

        $(this).postLike();

    });

    </script>
    <!--加一个点赞的功能--结束-->

搜索这个single.php

添加如下代码

<!--点赞功能开始-->
 <div class="post-like">
     <a href="javascript:;" data-action="ding" data-id="<?php the_ID(); ?>" class="favorite<?php if(isset($_COOKIE['bigfa_ding_'.$post->ID])) echo ' done';?>">喜欢 <span class="count">

       <?php if( get_post_meta($post->ID,'bigfa_ding',true) ){            

           echo get_post_meta($post->ID,'bigfa_ding',true);

       } else {

           echo '0';

       }?>

    </span>

    </a>
    </div>
    <!--点赞功能结束-->

将下面css加到style.css 或者DIY.CSS中

/*点赞功能美化开始*/
    .post-like{text-align:center;padding:10px}

  .post-like a {
    background-color: #21759B;
    border-radius: 20px;
    color: #FFFFFF;
    font-size: 15px;
    padding: 10px 10px;
    text-decoration: none;
    outline: none;
}

.post-like a.done, .post-like a:hover {
    background-color: #F44336;
    color: #ffffff;
}

    .post-like a.done{cursor:not-allowed}
/*点赞功能美化结束*/
