wordpress怎么添加点赞和添加功能
1、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;
}
1、<script type="text/javascript">
$(document).ready(function() {
$.fn.postLike = function() {
if ($(this).hasClass('done')) {
alert('您已赞过本博客');
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("<?php bloginfo('url');?>/wp-admin/admin-ajax.php", ajax_data, function(data) {
$(rateHolder).html(data);
});
return false;
}
};
$(document).on("click", ".favorite", function() {
$(this).postLike();
});
});
</script>
1、<div>
<a href="javascript:;" data-action="ding" data-id="<?php the_ID(); ?>" class="favorite<?php if(isset($_COOKIE['bigfa_ding_'.$post->ID])) echo ' done';?>">喜欢 <span>
<?php
if( get_post_meta($post->ID,'bigfa_ding',true) ){
echo get_post_meta($post->ID,'bigfa_ding',true);
} else {
echo '0';
}
?></span>
</a>
</div>
1、.post-like{text-align:center;padding:10px}
.post-like a{ background-color:#21759B;border-radius: 3px;color: #FFFFFF;font-size: 12px;padding: 5px 10px;text-decoration: none;outline:none}
.post-like a.done, .post-like a:hover{background-color:#eee;color:#21759B;}
.post-like a.done{cursor:not-allowed}
1、打开底部文件“footer.php”。找到标签</body>并在其前面插入刚才复制的代码。点击”更新文件“。或和点赞同一位置
