Adding a Meta Box to a Custom Post Type<\/h3>
The meta box is an editing screen window allowing users to add post metadata. It is useful for adding or modifying posts’ information, such as author details, publishing controls, and custom slug.<\/p>
While WordPress comes with default meta boxes, you may need a specific one for your custom post type. For example, the Movies <\/strong>custom post type may require the Genre <\/strong>meta box.<\/p>Using a meta box helps you add metadata to your content more quickly. Instead of entering the value individually, you can click data from the meta box to input it.<\/p>
To create a custom meta box, edit your theme’s functions.php <\/strong>or site-specific plugin’s code. In this tutorial, we will add the new meta box’s custom code to the plugin’s file.<\/p>Since the code varies depending on the meta box content and placement, refer to WordPress codex for more information. For this tutorial, we will explain how to build a custom Author <\/strong>meta box:<\/p>\n- Locate the custom-post-type.php<\/strong> file in your hosting file manager or FTP client.<\/li>\n\n\n\n
- Double-click the file to open the editor screen. Alternatively, download and open the file in a text or code editor.<\/li>\n\n\n\n
- Create an empty custom meta box by entering the following code:<\/li>\n<\/ol>
\/\/ Add meta box \nadd_action(\"add_meta_boxes\", \"add_author_meta_box\");\n\nfunction add_author_meta_box()\n{\n add_meta_box(\n \"author_meta_box\", \/\/ Meta box ID\n \"Author Details\", \/\/ Meta box title\n \"author_meta_box_callback\", \/\/ Meta box callback function\n \"article\", \/\/ The custom post type parameter 1\n \"side\", \/\/ Meta box location in the edit screen\n \"high\" \/\/ Meta box priority\n); \n}\nfunction author_meta_box_callback()\n{ \n\twp_nonce_field(‘author-nonce’, ‘meta-box-nonce’);\nglobal $post;\nplaceholder\n}<\/pre>\n- Add the meta box’s content by replacing the placeholder<\/strong> value. For this tutorial, we will add the author name and ID fields using the following code.<\/li>\n<\/ol>
\/\/ Add meta box content \n ?>\n\t<th><label for=\"athor_name_field\">Author Name<\/label><th>\n\t<td><input \ntype=\"text\"\nid=\"author_name\" \nclass=\"regular-text\" \nname=“Author_Name” \nvalue=“” \n\/> \n <td> \n <th><label for=\"author_id_field\">Author ID<\/label><th>\n\t<td><input \ntype=\"text\" \nid=\"author_id\" \nclass=\"regular-text\"\nname=“Author_ID”\nValue=””\n\/> \n <td> \n\t<?php <\/pre>\n- At the bottom of the code, add the following snippet to save the entered values:<\/li>\n<\/ol>
\/\/ Save meta box data\nadd_action ( 'save_post', 'author_save_postdata');\nfunction author_save_postdata( $post_id ) {\n\n\/\/ If this is an autosave, our form has not been submitted\nif ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) \nreturn $post_id;\n\n\t\/\/ Retrieve post id\n\tIf (‘article’ !== get_post_type() ) {\n\t\treturn $post_id\n}\n \t\/\/ Check the user's permissions\n \tif ( 'page' == $_POST['post_type'] ) {\n \nif ( ! current_user_can( 'edit_page', $post_id ) )\nreturn $post_id;\n \n} else {\n \nif ( ! current_user_can( 'edit_post', $post_id ) )\nreturn $post_id;\n}\n \n\/* OK, it is safe to save the data now. *\/\n \n\/\/ Sanitize user input.\n\n$mydata = sanitize_text_field( $_POST['Author_Name'] );\n\n$mydata = sanitize_text_field( $_POST['Author_ID'] );\n\n \n\/\/ Update the meta field in the database.\n\nupdate_post_meta( $post_id, 'Author_Name', $_POST['Author_Name'] ); \n\nupdate_post_meta( $post_id, 'Author_ID', $_POST['Author_ID'] ); \n }<\/pre>\n- In the file manager’s code editor, click the disk icon<\/strong> on the top right to save the change. If you edit the code locally, save and re-upload the updated file.<\/li>\n<\/ol>
The new meta box should appear if you open your custom post type’s edit screen.<\/p>
