Programmatically Pre-filling Ticket Submission Form Fields

You can programmatically pre-fill form fields on a ticket submission page using URL parameters, with form field names as parameter names and pre-fill data as values, or PHP POST requests.

Example Use Case:

Imagine you want to add an "Ask a Question" link linked with a Guest Support form to your product page, allowing users to submit inquiries directly through a ticket. In this scenario, you aim to pre-fill the subject field with the product name. Now, this feature will assist you in achieving that seamlessly.

Follow these simple instructions to learn how to effortlessly pre-fill your form fields.

Get Field Names:

To pre-fill input fields, you need to identify the field name, which you can obtain by following these steps:

  1. Login to Joomla! Administrator
  2. Click on Components -> Guest Support -> Forms




  3. From the list of forms, click on the name of the form you wish to pre-fill.
    Alternatively, you can select the form and then click on ... Actions -> Edit




  4. Now you can see the field name under each field. Refer to the screenshot below for reference:

Pre-fill Input Fields Using URL Parameters:

Example with SEF URL:

https://YOUR_WEBSITE/TICKET_SUBMISSION_PAGE_URL/?name=Jane Doe&email=EMAIL_ADDRESS&subject=Product Enquiry

Example with Non-SEF URL:

https://YOUR_WEBSITE/TICKET_SUBMISSION_PAGE_URL/index.php?option=com_guestsupport&view=createticket&id=1&name=Jane Doe&email=EMAIL_ADDRESS&subject=Product Enquiry

Explanation:

  1. https://YOUR_WEBSITE/TICKET_SUBMISSION_PAGE_URL/: This is the full URL where you can access the ticket submission page for the specific ticket submission form, for example: https://www.rcatheme.com/contact-support.
  2. id=1: This represents the form ID. Replace 1 with the form ID.
  3. name=Jane Doe: Here, 'name' is the input field name, and 'Jane Doe' is the full name of the user submitting the form. You can use this to pre-fill the user's name when they are logged in.
  4. email=EMAIL_ADDRESS: Here, 'email' is the input field name, and 'EMAIL_ADDRESS' is the user's email who is submitting the form. You can use this to pre-fill the user's email address when they are logged in.
  5. subject=Product Enquiry: Here, 'subject' is the input field name, and 'Product Enquiry' is the subject of this ticket.
