How to Display Custom Fields in Wordpress

1. Start your code editing software and use it to open the template file where you want to display the custom field. For instance, if you want to add the field content to single posts, you need to edit the 'single.php' template. Your template files are in the following location:/your-site/wp-content/themes/theme-name/Make sure you open the template file from the folder for your current theme, or the theme you wish to edit.
2. Add this line of code where you want the contents of the custom field to appear:
Replace 'field_name' with the name you want to give your field. Give the field a name with no capital letters and put underscores between words. In the above code, 'true' tells WordPress to return the content of the custom field as a single string. If you change that to 'false,' it will return an array. Do not use 'false' unless you know how to work with arrays.

3. Log into the WordPress dashboard and edit a post to add custom field content. Look for the 'Custom Fields' box under the editor box. If you do not see the 'Custom Fields' box, scroll up and click on 'Screen Options' under the text, 'Howdy.' Place a checkmark next to 'Custom Fields' and click 'Apply.' Type the name of your custom field, exactly as you typed it in the template file, in the input field below 'Name.' Add the content of your custom field in the text box under the heading 'Value.' Click the blue 'Update' button to publish the new custom field content. This content will now appear on your site, but it may need additional HTML or CSS code to display as you intended.
