How WordPress Runs Functions from Parent and Child Themes

  1. Functions in the Parent Theme: When WordPress loads a page, it looks for positions in its functions.php file. If it finds any parts there, it loads them and runs them.
  2. Functions in the Child Theme: If WordPress does not find the desired position in the parent theme, it looks for it in the child theme’s functions.php file. If it finds the process there, it loads and runs it.
  3. Overriding Functions: If a function is defined in the parent and child theme’s functions.php file, WordPress will use the one in the child theme, effectively overriding the one in the parent theme.
  4. Template Files: For template files such as header.php or footer.php, WordPress first looks in the child theme directory for the file. It looks in the parent theme directory if it does not find it there.

By performing its steps in this specific sequence, WordPress enables versatile theme modification without compromising the parent theme’s essential functionality. In the long term, this may make upgrades and maintenance less of a hassle since developers can alter fundamental design elements of the existing theme, without touching the core code.

  2. The child theme’s stylesheet contains a header that specifies the parent theme. This tells WordPress to load the parent theme’s stylesheet before the child theme’s.
  3. The child theme’s functions.php file can contain functions that add, modify, or remove functionality from the parent theme.
  4. The child theme can override any file in the parent theme by placing a copy of the file in its directory with the same name and directory structure. WordPress will use the child theme file instead of the parent theme file.
