We found that customizing the Tevolution or Theme working with it is becoming difficult for you guys. Thus here is a short tutorial which can make it bit easier for you. It can help you find the actual code location in the files.

There are many hooks defined in the Tevolution using which you can customize the code or add your code easily without touching initial code.

USE OF HOOK IN WORDPRESS: It allows you to call functions in the plugin on it’s specific location or event execution. You can also call more than one function at a location.

HOW TO USE HOOKS:

In Tevolution plugin, to use hooks we need to understand two methods:

• Do_action():

Hooks are defined in the plugin using do_action() method like this:

Do_action(‘hook_name’);

When this function is called all the add_action()s related with this hook name is called and thus the functions are also called.

• Add_action():

do_action is linked to an another function called add_action() to run our function code.

Add_action can be used by you in the related file while do_action()s are defined by the Templatic developers.

We can use it this way:

Add_action(‘hook_name’,’function_name’,Priority,Accepted_Args);

Here,

Function_name is the name of the function to be called on do_action(‘hook_name’) call.

Priority is an option value if you are having multiple add_action then you can give it’s value. It is a digital value starting from 10. Priority with 10 will be executed first then at 11 and so on.

Accepted_Args is a numerical value which represents the number of arguments the function_name() is accepting. It is also an optional argument.

EXAMPLE: 

• Suppose, you are using Nightlife theme. Now, you want to add anything before breadcrumbs on single pages, then first you will need to do add_action like this:
• [CODE]add_action(‘templ_before_single_container_breadcrumb’,’my_code’);[/CODE]
• You can add this code in any file. Just make sure that the file is executed on the related pages. Here, single pages. For this example, you can add the code in Nightlife’s Custom_functions.php file.
• Now, in above line of code, my_code is a function. So you will also need to define a function with that name. So overall, my code will look like this:
• [CODE]add_action(‘templ_before_single_container_breadcrumb’,’my_code’);
  function my_logo()
  {
  echo “Here is my code.”;
  }[/CODE]
• If you want to remove something from the theme. For example, to remove breadcrumbs, we have used this function – single_post_type_breadcrumb(). So you will need to remoce action for the same like this:
• [CODE]remove_action(‘templ_before_single_container_breadcrumb’,’single_post_type_breadcrumb’);[/CODE]

First make changes in the child theme(Ex.: Nightlife). If the changes are not affecting there then only touch “Supreme”.
