Form validation in same page / url

[eluser]Pintossauro[/eluser]
Hi all,

In my application i have Projects that can have Tasks. I created a form to add a Task in a Project. I also configured routes.php:

Code:

$route['([0-9]+)/tasks/add'] = "task/add/$1";

(the first argument is the project id) and i have a link in the projects page:

Code:

anchor($project_id.'/tasks/add', 'Add new task')

With this the user will be redirected to my <b>add($project_id)</b> function in my Task controller which will load the 'task/add' view with the correspondent project information and the form to add the new task (the url in the browser will still be, e.g., "4/tasks/add").

Then when the user submits his information i have a function <b>"insert_task"</b> in my Task controller that validates the data.

If all OK insert data in the database and load the view with the list of tasks in the project. If not i wanted the user to see
the <b>'4/tasks/add'</b> view again with the errors but if i do <b>$this->load->view('task/add')</b> like i did in my function "add" the url will be <b>.../index.php/task/insert_task </b> and not <b>../index.php/4/tasks/add</b> as i wanted.


Maybe i'm not understanding the MVC pattern correctly or am i using two functions (add - to load the form view - and insert_task - to validate and insert the task in
the DB) when not necessary.

Does someone have an suggestion how to solve this?

Thanks for your attention,
Pintossauro.

Maybe this is confusing. I'll try to simplify:

Basically I access a URL like <b>index.php/4/tasks/add</b> by a link with the <b> href="/4/tasks/add">Add task</b> that calls the Add function in the Task controller passing the project id as argument (due to the definition in routes.php). When a user submits a new task, if the <b>validation in insert_task() method</b> fails, i wanted to show the same URL <b>index.php/4/tasks/add</b> with the input errors but if i just load the same view in my validation function (<b>$this->load->view(task/add)</b>) the URL will be <b>index.php/task/insert_task</b> and not the <b>index.php/4/tasks/add</b> that i want.

This is just a matter of the "aspect" of the URL because the application works perfectly.

Any ideas?

The form should be submitting to current_url(), if validation is successful, redirect, if not, show the form again with validation errors.
