What is WordPress Hook: page_template
The page_template hook in WordPress is used to control the template that is used to display a specific page on a website. It allows developers to customize the appearance and functionality of individual pages by specifying a custom template file.
Understanding the Hook: page_template
The page_template hook is located within the get_page_template() function in WordPress. This function is responsible for retrieving the path to the page template file that should be used to display a specific page. The hook allows developers to modify the template file path before it is returned.
Hook Parameters (if applicable): page_template
The page_template hook does not accept any arguments or parameters.
Hook Doesn’t Work: page_template
If the page_template hook doesn’t work as expected, it may be due to incorrect usage or conflicts with other functions or plugins. To troubleshoot, developers should check for any syntax errors in their code and ensure that the hook is being used in the appropriate context within the WordPress template files.
