How to Add Custom Fields in WordPress (Beginner’s Guide)
Adding custom fields in WordPress is very easy. First, you need to edit the post or page where you want to add custom fields.
On the post edit screen, you will see the custom fields meta box. By default, this meta box is hidden. You need to click on the “Screen Options” tab at the top right corner of the screen to reveal it.
Once you click on it, the custom fields meta box will appear.
Now you can start adding custom fields to your WordPress post or page. Simply enter the name of your custom field in the “Name” column and its value in the “Value” column.
You can add as many custom fields as you want. Once you are done, don’t forget to click on the “Add Custom Field” button to save your changes.
How to Display Custom Fields Data in WordPress
Once you have added custom fields to a post or page, you can display that data in your WordPress theme.
To do that, you need to edit the template file where you want to display the custom field data. For example, if you want to display custom field data on your single post template, then you need to edit the “single.php” file.
Inside the template file, you can use the get_post_meta() function to retrieve and display custom field data.
The get_post_meta() function takes three parameters – the ID of the post/page, the name of the custom field, and a Boolean value specifying whether to return a single value or an array.
Here is an example of how you can use the get_post_meta() function to retrieve and display custom field data:
ID, ‘color’, true );
echo $color;
?>
In the example above, we are retrieving the custom field data with the name “color”. The third parameter is set to “true” so that the function returns a single value.
If we had set the third parameter to “false”, then the function would have returned an array of values.
How to Update Custom Fields in WordPress
Updating custom fields in WordPress is very easy. Simply edit the post or page where you want to update the custom field data.
On the post edit screen, scroll down to the custom fields meta box and click on the “Edit” link next to the custom field that you want to update.
This will open the custom field editor where you can change the name and value of the custom field.
Once you are done, don’t forget to click on the “Update Custom Field” button to save your changes.
How to Delete Custom Fields in WordPress
Deleting custom fields in WordPress is just as easy as adding or updating them. Simply edit the post or page where you want to delete the custom field.
On the post edit screen, scroll down to the custom fields meta box and click on the “Delete” link next to the custom field that you want to delete.
This will open a confirmation popup where you need to click on the “OK” button to confirm that you want to delete the custom field.
Conclusion
Custom fields are a great way to add extra data to your WordPress posts and pages. They are very easy to add, update, and delete.

Adding custom fields to your WordPress theme is simple. First, you need to add a custom field to your theme’s functions.php file. To do this, open your theme’s functions.php file and add the following code:
function my_custom_fields($fields) {
$fields[‘my_custom_field’] = ‘My Custom Field’;
return $fields;
}
add_filter(‘custom_fields_register’, ‘my_custom_fields’);
This code will add a new custom field to your WordPress theme. Next, you need to add the custom field to your theme’s templates. To do this, open your theme’s header.php file and add the following code:
ID, ‘my_custom_field’, true); ?>
This code will display the custom field on your WordPress posts and pages.
You can also use custom fields to create custom taxonomies. To do this, open your theme’s functions.php file and add the following code:
function my_custom_taxonomies() {
register_taxonomy(‘my_custom_taxonomy’, ‘post’, array(
‘labels’ => array(
‘name’ => ‘My Custom Taxonomy’,
‘singular_name’ => ‘My Custom Taxonomy’,
),
‘hierarchical’ => true,
));
}
add_action(‘init’, ‘my_custom_taxonomies’);
This code will create a new custom taxonomy for your WordPress posts.
