Hello,
I am also new to CodeIgniter. And building a webside using CI+FormGenLib
I have to use multiple forms in a page.
My Problem:
I can not stop the code check the unsubmitted form with the other ?automaticly?.
*Errors are different. One's error is not shown under other's error list.
Here is my code to generate required forms using formgenlib under my controller.
Code:
$this->load->library('form');
$login_form = new $this->form;
$login_form
->open()
->col(240, 'left', 'left')
->text()
->col(170, 'left', 'left')
->password()
->col(100, 'left', 'right')
->submit('', 'submit_login')
->col(0)
->validate();
$data['login_form'] = $login_form->get();
$this->load->view('overal_header', $data);
$login_form->clear();
$radio = array(
array('', ''),
array('', ''),
);
$register_form = new $this->form;
$register_form
->open()
->fieldset()
->text()
->text()
.
.
.
->submit('', 'submit_form');
if($this->input->post('submit_form'))
{
$register_form->validate();
if($register_form->valid)
{
//do the stuff here...
}
}
$data['form'] = $register_form->get();
$data['errors'] = $register_form->errors;
$register_form->clear();
$this->load->view('page_welcome', $data);
$this->load->view('overal_footer');---
By the way, If I click on first button, //do the stuff doesn't work. But errors are shown.

Controller
Code:
/* test */
function test()
{
$this->form
->text('Name', 'name', 'required')
->submit('Login', 'login');
$this->form->validate();
if($this->form->valid)
{
echo 'form 1 Valid';
}
$data['form1'] = $this->form->get();
$data['error1'] = $this->form->errors;
$this->form->clear();
$this->form
->text('Name', 'name', 'required')
->submit('Register', 'register');
$this->form->validate();
if($this->form->valid)
{
echo 'form 2 Valid';
}
$data['form2'] = $this->form->get();
$data['error2'] = $this->form->errors;
$this->load->view('test_view', $data);
}
// end test

Code:
<h2>Login Form</h2>
<h5>Error</h5>
<?=$error1?>
<?=$form1?>
<h2>Register</h2>
<h5>Error</h5>
<?=$error2?>
<?=$form2?>Form Generation Library - El Forum - 05-13-2012

We found out that, this is a bug with BaRzO. The same code works under v1.0.1 but not v2.0...

From what I saw things get more complicated when you are working with relationships, foreign keys etc. If you have another simple example with relations involved feel free to share
In my current project I often have to manage relationships between 5 or 6 tables. [/quote]
FYI, I'm managing relationships across 20+ tables & two databases, with multiple FK in each table (upto 4), so it's a little more complicated than just a couple of relationships. And one of the DBs has recursive FKs across almost 1m records.
That said, whatever works. There is no 'right' way as long as it does what you need.
Chris.

I have a multi-page form. Basically, you have to store the results of the first form somewhere. I store it in the session object, which is saved to the db. Not the cookie, which is unsafe and can only store about 4k.
Code:
if ($this->form->valid) {
// validate your first form here
// save your form to the user's session
$this->session->set_userdata($post);
// redirect to second form
redirect('subscription/review');
}Then I just pull in the old form data as if it was part of the second page form
Code:
function review() {
// get data from the first form if you need it to create the second form/page
$session_form = $this->session->all_userdata();
// create the second form here
if ($this->form->valid) {
// get the data from the first form
$form_data = $this->session->all_userdata();
// validate second form here
// save any data you need for thankyou page
$this->session->set_flashdata($data);
redirect('subscription/thankyou');
}
}Note that your thankyou function should clear out all session data to be safe.
Code:
function thankyou() {
$ty_msg['welcome_message'] = $this->session->flashdata('welcome_message');
$this->load->view("thankyou", $ty_msg);
$this->session->sess_destroy();
}Works well, but you have to make sure sessions are working properly and that stuff like AJAX calls are not reseting session data.
HTH,
Chris.

How do you deal with errors after form validation?
I have a form that validates properly, but then needs to check some data against an API.
When the external checks fail, how can I reload the form with errors. Here's what I have now and it doesn't work (form is blank)
Code:
if ($this->form->valid)
{
$post = $this->input->post();
$this->load->library('form'); // form creation
$return_data = go_out_to_my_api($post);
if(!$return_data) {
$api_error = "There has been an API error";
$this->form->add_error('name',$api_error);
$data['form_errors'] = $this->form->errors;
$this->load->view("review", $data);
}

Figured it out. Turns out output buffering was the problem. If you exit in the middle of a code block after calling a view, output buffering will stop it from displaying. You have to echo manually....

Maybe I'm up too late, or am just having difficulties...
I'm trying to set the config/form.php
Code:
$config['element_suffix'] = '';Because in some cases, I would like to have a break (
Code:
<br />So I've tried with $this->config->set_item, not working...
I tried doing
Code:
->checkgroup('Example', $example, 'Please select:', $selectedItems, '', array('label_suffix' => '<br />'))This library is very nice and I plan on making a contribution with my first paying job
Any help would be GREATLY appreciated.
Thank you.

Use this...
Code:
->checkgroup('Example', $example, 'Please select:', $selectedItems, '')
->br()
