Codeigniter 3 form validation into array - php

Question

I'm using codeigniter 3, and I'm trying to use the form_validation library.
Basically, if validation fails, I'm catching the input data and then sending it back to the form.
So I'm sticking all form data in an array, like so:
// add input data to array
$org_data = array(
'org_id' => $this->input->post('org_id'),
'p_org_id' => $this->input->post('p_org_id'),
'account_ref' => $this->input->post('account_ref'),
'org_name' => $this->input->post('org_name'),
'address1' => $this->input->post('address1'),
'address2' => $this->input->post('address2'),
'address3' => $this->input->post('address3'),
'town' => $this->input->post('town'),
'county' => $this->input->post('county'),
'pcode' => $this->input->post('pcode'),
'phone' => $this->input->post('phone'),
'support_email' => $this->input->post('support_email'),
'notify_return' => $this->input->post('notify_return'),
'notify_email' => $this->input->post('notify_email'),
'email_interval' => $this->input->post('email_interval'),
'renewal_date' => $this->input->post('renewal_date'),
'login_reminder' => $this->input->post('login_reminder'),
'default_fireaware' => $this->input->post('default_fireaware'),
'open_training_url' => $this->input->post('open_training_url'),
);
All fine!
Now, to send the data back to the form, I am using the below.
$this->data['org_id'] = array(
'name' => 'org_id',
'id' => 'org_id',
'type' => 'text',
'value' => $this->form_validation->set_value('org_id'),
);
BUT
I don't want to create one of these for every input, so ideally I'd like to use a loop to create these. But I cant get it to work, I am getting undefined variable errors.
This is the loop in progress:
foreach($org_data as $key => $value){
$this->data['$key'] = array(
'name' => '$key',
'id' => '$key',
'type' => 'text',
'value' => $this->form_validation->set_value('$value'),
);
}
Can I use a loop to do this?
What are your thoughts?

Answer 1

use validation like this
$config = array(
array(
'field' => 'username',
'label' => 'Username',
'rules' => 'required'
),
array(
'field' => 'password',
'label' => 'Password',
'rules' => 'required'
),
array(
'field' => 'passconf',
'label' => 'Password Confirmation',
'rules' => 'required'
),
array(
'field' => 'email',
'label' => 'Email',
'rules' => 'required'
)
);
$this->form_validation->set_rules($config);
if ($this->form_validation->run() == FALSE) {
$data['errors'] = validation_errors();
$this->load->view('yourview', $data);
} else {
$userData = $this->input->post();
$this->load->view('yourview', $data);
}

yeah i think this is the part to clarify - you don't need to do that at all -- thats the advantage of using set_value('fieldName'), it automatically echoes out the value. Same - on the form - with form_error( 'fieldName' ) it will display the field specific error message.
