  How to create duplicate for default opencart contact us form with additional fields
  
  In my opencart template i need to create a form which is similar to contact form with the fields Name,Email and Mobile number.I have already used the default contact us form in my contact us page.I need to create this new form for another page.Is there any free extension available?Or else how can we implement our own form?
  
  A:
  
  I am not going to recommend any extension (this is not the place to do so) but i can tell you some steps duplicate the contact from.
  First you need to duplicate three files in their respective directories  
  
  catalog\language\english\information\contact.php
  catalog\view\theme\default\template\information\contact.tpl
  catalog\controller\information\contact.php
  
  and name them form.php,form.tpl,form.php
  All changes after this point will be performed on these files only
  now change you controller class name to ControllerInformationForm
  other than this you will have to edit several things in controller file like change contact.tpl to form.tpl , load correct language file using $this->language->load('information/form'); 
  after making necessary changes to controller file, your new form can be accessed using website.com/index.php?route=information/form
  now for additional field take one existing field like name and do all things which are done for name in these 3 files with your new field
  Note don't do $mail->setSender($this->request->post['name']); for you new field its different
  now lets in tpl you have new field in tpl like this 
  <input type="text" name="city" value="<?php echo $city; ?>" />
  
  then in your controller change following line
  $mail->setText(strip_tags(html_entity_decode($this->request->post['enquiry'], ENT_QUOTES, 'UTF-8')));
  
  to 
  $mail->setText(strip_tags(html_entity_decode($this->request->post['enquiry'] . " " . $this->request->post['city'], ENT_QUOTES, 'UTF-8')));
  
  Disclaimer : This not a full set of instruction but this is enough for you to start and to ask better question if you face any problem
