AJAX (Asynchronous JavaScript and XML) is a technique used to update parts of a web page without having to refresh the entire page. In WordPress, AJAX can be used to update a posts feed on a page without having to refresh the entire page. However, it’s not uncommon for developers to encounter issues when trying to update a posts feed using AJAX in WordPress. One such issue is that the AJAX feed update may be ignoring the “post__not_in” parameter or possibly the data is not being passed correctly. In this article, we will go over some common causes and solutions for this issue.

The “post__not_in” parameter is used in WordPress to exclude certain posts from a query. When using AJAX to update a posts feed, it’s important to make sure that this parameter is being passed correctly to the server. One common cause of this issue is that the parameter is not being passed correctly in the AJAX request. This can happen if the parameter is not being added to the data object that is being passed in the AJAX request, or if the parameter is being added incorrectly.

To resolve this issue, make sure that the “post__not_in” parameter is being added correctly to the data object that is being passed in the AJAX request. For example, the following code shows how to add the “post__not_in” parameter to an AJAX request:

Copy code$.ajax({
        url: ajax_url,
        type: 'post',
        data: {
            action: 'load_more_posts',
            post__not_in: post_not_in
        },
        success: function(response) {
            // Handle the response
        }
    });

In this example, the “post__not_in” parameter is being added to the data object with the key “post__not_in” and the value “post_not_in”.

Another common cause of this issue is that the “post__not_in” parameter is not being used correctly in the server-side code. This can happen if the parameter is not being passed correctly to the WP_Query object, or if the parameter is not being used correctly in the query.

To resolve this issue, make sure that the “post__not_in” parameter is being passed correctly to the WP_Query object and that it’s used correctly in the query. For example, the following code shows how to use the “post__not_in” parameter in a WP_Query object:

Copy code$args = array(
    'post__not_in' => $post__not_in
);
$query = new WP_Query( $args );

In this example, the “post__not_in” parameter is being passed to the WP_Query object with the key “post__not_in” and the value “$post__not_in”.

Another possible cause of this issue is that the data passed with the AJAX request is not being passed correctly to the server-side script. This can happen if the data is not being passed with the correct format, or if the server-side script is not handling the data correctly.

To resolve this issue, make sure that the data passed with the AJAX request is being passed with the correct format and that the server-side script is handling the data correctly. For example, the following code shows how to handle data passed with an AJAX request in a server-side script:

Copy code$post__not_in = $_POST['post__not_
