How to use ajax in wordpress
Now I will share with you a detailed explanation of ajax writing method based on wordpress. It has a good reference value and I hope it will be helpful to everyone.
I wanted to make changes to a wordpress template program, and thought of the convenience of ajax, so I did some research.
The following is the usage method and code:
js page is as follows
<script>
var ajaxurl = '<?php echo admin_url('admin-ajax.php')?>';
function getVideo(id){
//必须使用以下里面才能正常使用jquery
jQuery(document).ready(function($){
var data={
tape:id,
//这里尤为重要，action的参数要和请求的函数名一致
action : 'get_ajax_video',
}
$.post(ajaxurl, data, function(response) {
$('.player').html(response);
});
});
}
</script>AJAX request should Point to wp-admin/admin-ajax.php. Although the word "admin" is a bit misleading, even the ajax request at the front desk should be located at admin-ajax.php.
admin-ajax requires a parameter "action". Admin-ajax requires this parameter to handle the request. It usually triggers a hook, which varies depending on whether you are logged in or not.
Then write the function in the plug-in or theme
function get_ajax_video() {
// 输出响应
header( "Content-Type: application/json" );
echo json_encode($html);
exit;//这个停止一定要写
}
//函数名对应添加上，第一个表示用户没有登录时，这里全部都一样处理
add_action( 'wp_ajax_nopriv_get_ajax_video', 'get_ajax_video' );
add_action( 'wp_ajax_get_ajax_video', 'get_ajax_video' );The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
