Custom Wordpress Create Wishlist Without Plugin

To create a wishlist feature in WordPress without using a plugin, you can follow these steps:

1. Create a custom post type for the wishlist items. This will allow you to store each item as a separate post, with its own title, content, and metadata. You can do this by using the register_post_type() function in your theme's functions.php file or by creating a custom plugin to hold the code.
2. Create a form for users to add items to the wishlist. This form should include fields for the item name, a description, and any other relevant information. You can use the wp_insert_post() function to add the submitted form data as a new wishlist item post.
3. Display the wishlist items to the user. You can use the WP_Query class to retrieve the wishlist items and display them on a page or template. You can also include options for the user to edit or delete items from their wishlist.
4. Implement user-specific wishlists. To create individual wishlists for each user, you can store the wishlist items as post metadata associated with the user's account. You can use the update_user_meta() function to add this data and the get_user_meta() function to retrieve it when displaying the wishlist.

Keep in mind that creating a custom wishlist feature in WordPress without using a plugin will require some coding knowledge and may be more time-consuming than using a pre-existing plugin. However, building the feature yourself will allow you to customize it to your specific needs and requirements.

Create a custom post type for wishlist items. You can do this by adding the following code to your functions.php file:

function create_wishlist_post_type() {

  register_post_type( 'wishlist',

    array(

      'labels' => array(

        'name' => __( 'Wishlist' ),

        'singular_name' => __( 'Wishlist Item' )

      ),

      'public' => true,

      'has_archive' => true,

      'supports' => array( 'title', 'editor', 'custom-fields' )

    )

  );

}

add_action( 'init', 'create_wishlist_post_type' );

 Display the wishlist items on the front-end of your website. You can do this by creating a template file (e.g., template-wishlist.php) and using a WP_Query loop to retrieve and display the wishlist items:

<?php

$args = array(

  'post_type' => 'wishlist',

  'posts_per_page' => -1

);

$wishlist_query = new WP_Query( $args );

if ( $wishlist_query->have_posts() ) :

  while ( $wishlist_query->have_posts() ) : $wishlist_query->the_post();

    the_title();

    the_content();

  endwhile;

endif;

wp_reset_postdata();

?>

Add a form to allow users to add items to the wishlist. You can do this by creating a template file (e.g., template-add-to-wishlist.php) and using the wp_insert_post() function to insert a new wishlist item into the database:

<?php

if ( isset( $_POST['submit'] ) ) {

  $title = sanitize_text_field( $_POST['title'] );

  $content = sanitize_textarea_field( $_POST['content'] );

  $new_wishlist_item = array(

    'post_type' => 'wishlist',

    'post_title' => $title,

    'post_content' => $content,

    'post_status' => 'publish'

  );

  wp_insert_post( $new_wishlist_item );

}

?>

<form method="post">

  <label for="title">Title:</label><br>

  <input type="text" id="title" name="title"><br>

  <label for="content">Content:</label><br>

  <textarea id="content" name="content"></textarea><br>

  <input type="submit" name="submit" value="Submit">

</form>

Allow users to mark items as "purchased" or remove them from the wishlist. You can do this by adding a custom field to the wishlist items (e.g., "purchased") and using the update_post_meta() function to update the value of this field when the user clicks a button:
