wordpress custom php use wp query

To use the WordPress custom PHP code with WP_Query, follow these steps:

1. Step one: Begin by defining your custom query parameters. These parameters will determine what content you want to retrieve from the WordPress database. You can specify parameters such as post type, taxonomy, author, date, and more.

2. Step two: Create a new instance of the WP_Query class. This class is built into WordPress and allows you to perform queries on the database. Use the following code to create a new instance:

$query = new WP_Query( $args );

Here, $args represents an array of query parameters that you defined in step one.

1. Step three: Execute the query and retrieve the results. Use the following code to execute the query and retrieve the posts:

if ( $query->have_posts() ) {
    while ( $query->have_posts() ) {
        $query->the_post();
        // Your code to display the post content goes here
    }
} else {
    // Code to handle the case when no posts are found
}

Inside the while loop, you can access the post data using functions like the_title(), the_content(), the_permalink(), and more.

1. Step four: After you have finished using the query results, reset the post data. Use the following code to reset the post data:

wp_reset_postdata();

This step is important to ensure that the global $post variable is restored to its original state.

That's it! You have successfully used WP_Query to retrieve and display custom content from the WordPress database. Remember to customize the query parameters and the code inside the loop according to your specific needs.
