我正在使用wordpress 4.9.8 和PHP 7.1.8 我在新的帖子屏幕上添加了一个按钮：
我尝试按以下方式触发按钮：
add_action( \'media_buttons\', \'add_my_media_button\', 99 );
function add_my_media_button() {
$post = $GLOBALS[\'post_ID\'];
echo "<a href=\'#\' id=\'insert-my-media\' data-post-id=\'{$post}\' class=\'button\'>Own content</a>";
}
add_action( \'wp_ajax_my_action\', \'updateContent\' );
function updateContent() {
$post_id = intval( $_POST[\'post_id\'] );
wp_die(); // this is required to terminate immediately and return a proper response
$post = array(
\'ID\' => $post_id,
\'post_content\' => \'Insert this content\',
);
// Update the post into the database
wp_update_post( $post );
}
add_action( \'admin_footer\', \'my_media_button_script\' );
function my_media_button_script() {
?>
<script>
jQuery(document).ready(function ($) {
$(\'#insert-my-media\').click(function () {
var post_id = $(this).attr(\'data-post-id\');
var data = {
\'action\': \'updateContent\',
\'post_id\': post_id
};
console.log("test: " + ajaxurl)
console.log(data)
// since 2.8 ajaxurl is always defined in the admin header and points to admin-ajax.php
jQuery.post(ajaxurl, data, function (response) {
alert(\'Got this from the server: \' + response);
});
});
});
</script>
<?php
}
但是，按submit时，我会得到：
任何关于我为什么会出现这个错误的建议。
