To create child theme
If you need to customize the theme code, of course, you do not want to modify it everytime you update the theme. That’s where the child theme take action.
We provided the child theme for you within the zip file you downloaded from themeforest. All you need to do is uploading the “traveltour-child.zip” file to “Appearance > Themes” section and activate it. ( just like how you upoad the theme )

Adding / modify php code
Our theme wrap every function with if( !function_exists(‘some_function’) ) command. If you need to modify any function, just declare it in the function.php file of the child theme and it’ll overwrite the existing one.
However, you need to use hook and action to modify the plugins since the plugin is loaded before the theme files.
