Steps to Add Custom Fields Automatically

Step 1: Install A Code Snippet Plugin

First, you need to install a code snippet plugin. This plugin will let you add custom code to your WordPress site. Here are some popular code snippet plugins:

• Code Snippets
• WPCodeBox

Go to your WordPress dashboard. Click on Plugins. Then click on Add New. Search for one of the plugins above. Install and activate it.

Step 2: Add The Custom Code

Now, you need to add the custom code. This code will add the custom fields when you publish a post. Follow these steps:

1. Go to your WordPress dashboard.
2. Click on Snippets or the name of your code snippet plugin.
3. Click on Add New or Add Snippet.
4. Give your snippet a name. For example, “Add Custom Fields on Publish”.
5. Copy and paste the code below into the code box.

function add_custom_fields_on_publish($post_id) {
    // Check if the post is already saved
    if (wp_is_post_revision($post_id)) {
        return;
    }

    // Add custom fields
    update_post_meta($post_id, 'custom_field_key_1', 'Custom Field Value 1');
    update_post_meta($post_id, 'custom_field_key_2', 'Custom Field Value 2');
}
add_action('publish_post', 'add_custom_fields_on_publish');
    

This code does a few things:

• It checks if the post is a revision.
• If it is not, it adds two custom fields to the post.

You can change the keys and values to your needs. For example, change ‘custom_field_key_1’ to ‘author_name’. Change ‘Custom Field Value 1’ to the actual author’s name.

Step 3: Save And Activate The Code Snippet

After adding the code, you need to save and activate the snippet. Click on Save or Save Changes. Then, make sure the snippet is active.

Step 4: Test The Custom Fields

Now, you need to test if the custom fields are added. Create a new post. Write some content. Click on Publish. Go to the post you just published. Click on Edit. Scroll down to the custom fields section. You should see the custom fields you added. If you do not see them, check your code. Make sure it is correct.
