wp_insert_post does not return postid in wp ajax call

Here is a sample of my code in php:

add_action(‘wp_ajax_nopriv_my_action_restore_post’, ‘my_action_restore_post’);
add_action(‘wp_ajax_my_action_restore_post’, ‘my_action_restore_post’);

function my_action_restore_post(){

$newPost = array(
‘post_content’ => ‘sample content’
,’post_name’ => ‘sample name’
,’post_title’ => ‘sample title’
,’post_status’ => ‘sample status’
,’post_type’ => ‘sample post type’
,’post_author’ => ‘sample author’
,’ping_status’ => ‘sample status’
,’post_parent’ => ‘sample parent’
,’post_password’ => ‘sample password’
,’post_excerpt’ => ‘sample excerpt’
,’comment_status’ => ‘sample comment status’
);

$post_id = wp_insert_post($newPost, true);

echo $post_id;

wp_die();
}

And here is my code in js file:

var data = {
‘action’: ‘my_action_restore_post’,
‘restoreblogPostId’: blogPostArr
}

jQuery.ajax({
type: “POST”,
url: ajax_object.ajaxUrl,
data: data,
error: function(jqXHR, textStatus, errorThrown){
alert(“error occured: ” + jqXHR);
},
success: function(data) {
alert(data);
}
});

Hi Lulu,

You will have better results if you tell AJAX what type of data comes back from your function call. Here’s an example that returns JSON.

function my_action_restore_post(){

	$restored_post = whatever_you_need_to_do_here();
	$response = array('post_id' => $restored_post, 'message' => 'The post restore was successful');

	// send back JSON
	$response = json_encode( $response  );
	header( "Content-Type: application/json" );
	echo $response;
	exit;
}

Your problem is the use of wp_die(), which sends an HTTP 500 error code to your browser. So instead of these two lines:

echo $post_id;
wp_die();

You should do something like this:

if (!empty($post_id)) {
	 echo $post_id;
}
exit;

In your JS, you should check whether the data variable is empty; if it is, then your call to wp_insert_post() failed.

Hi ancawonka and diondesigns,

Thanks for your suggestions. I’ll try it and post again if works.

Ah, thanks @diondesigns, I didn’t know about the HTTP 500 code from wp_die.
