For the proper functioning of the module, you need to add some hook in prestashop core files –

1.) Add Hook

{hook h='DisplayWkCustomerLoginForm'}

in Front-Office

File name – login-form.tpl
Path – /themes/_YOUR_THEME_NAME_/templates/customer/_partials/

Position – In Login Form with id=”login-form”, Inside {block name=’login_form_fields’} section and after {/foreach}

2.) Add Hook

{hook h='DisplayWkCustomerContactForm'}

in Front-Office

A.) File name – contactform.tpl
Path – /modules/contactform/views/templates/widget

Position – Inside <section class=”form-fields”> after Message filed <label>…….</label>

B.) File name – contactform.tpl
Path – /themes/_YOUR_THEME_NAME_/modules/contactform/views/templates/widget

Position – Inside <section class=”form-fields”> after Message filed <div class=”form-group”>……</div>

3.) Add Hook

{hook h='DisplayWkAdminLoginForm'}

in Back-Office

File name – content.tpl
Path – /admin/themes/default/template/controllers/login

Position – Inside Login Form with id=”login_form”, After Password field <div class=”form-group”>……</div>

4.) Add Hook –

Hook::exec('actionWkAdminLoginControllerSubmit');

in Back-Office

File name – AdminLoginController.php
Path – /controllers/admin/

1. Classes/form – CustomerForm.php
function name – validate()

2. Classes/form – CustomerLoginForm.php
function name – submit()

3. modules/contactform – contactform.php
function name – sendMessage()
