Detailed explanation of ajax writing method in wordpress

I wanted to make changes to a wordpress template program. Thinking of the convenience of ajax, I did some research. This article mainly shares 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. Let’s follow the editor to take a look, I hope it can help everyone.

The following is the usage method and code:

js page is as follows

AJAX request should point to wp-admin/admin-ajax.php. Although the word "admin" is a bit misleading, even front-end ajax requests 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' );
