Message:

I'm creating an app and I want to enable users to change their data and password. I've created an email changing form and it works, but I've got a problem with password.
I've got a page localhost:8000/user/{id} and here the buttons: edit email and edit password. Edit email is working and when I click on editing password - I got a blank page on localhost:8000/user/{id}/change_password
(enter image description here enter image description here). Th PassType doesn't show there.

There are no syntax error on localhost:8000/user/{id} and localhost:8000/user/{id}/change_password.

I've added a function edit_pass to UserController, crated PassType (where is the form to change password) and make a template edit_password.html.twig.

I don't know where is the problem. I did the same thing as with other Forms which work. I've tried to clear the edit_password template (I've just left the base_html there and put some text) cause I've thought there is a problem in it, but it was still a blank page on localhost:8000/user/{id}/change_password.

My Answer:
A PHP template is a file that contains a mixture of HTML, CSS, and PHP code. It is used to create a consistent layout for a website by separating the design and content. Templates make it easier to update the design of a website without having to change every individual page.

Here is an example of a simple PHP template:

php

In this template, we have placeholders for the title, header, and content of the page. These placeholders will be filled in with actual content when the template is used to generate a webpage. This allows for easy customization and maintenance of the website.
