How can I retrieve an array in Simple MVC Framework to show error messages if some input fields are not valid?
Controller:
public function index($error)
{
$data ['title'] = $this->language->get('welcome_text');
View::renderTemplate('header', $data);
View::render('insert/form', $data);
View::renderTemplate('footer', $data);
}
public function save()
{
if (isset($_POST)) {
$data ['is_valid'] = \Helpers\Gump::is_valid($_POST, array(
'firstname' => 'required|min_len,2'
));
if ($data ['is_valid'] === true) {
// continue
} else {
$this->index($data ['is_valid']); // show error messages
die();
}
}
}
View:
<div class="alert alert-danger"><?php var_dump($error); ?></div>
... <button type="submit">Save (calls save())</button>
var_dump($error) always shows bool(false).
Basically you wasn't sent error to render, as i see.
public function index($error)
{
$data ['title'] = $this->language->get('welcome_text');
$data ['error'] = $error;
View::renderTemplate('header', $data);
View::render('insert/form', $data);
View::renderTemplate('footer', $data);
}
View
<div class="alert alert-danger"><?php var_dump($data['error']); ?></div>

How to pass value to drop down list in CodeIgniter?
This is my view file HTML code:
<div class="form-group">
<select name="department" id ="department">
<?php
foreach($dept as $country)
{
echo '<option value="'.$country['dept_id'].'">'.$country['managers_name'].'</option>';
}
?>
</select>
</div>
This is my controller code:
public function department()
{
$this->load->model('insert_model');
$data['dept'] = $this->insert_model->category_name_get();
}
This is my model file code:
function category_name_get()
{
$query = $this->db->get('dept');
if ($query->num_rows >= 1)
{
foreach($query->result_array() as $row)
{
$data[$row['dept_id']]=$row['managers_name'];
}
return $data;
}
}
I think you are searching for Adding Dynamic Data to the View
Data is passed from the controller to the view by way of an array or an object in the second parameter of the view loading method. Here is an example using an array:
$data = array(
'title' => 'My Title',
'heading' => 'My Heading',
'message' => 'My Message'
);
$this->load->view('blogview', $data);
In your case $data contains the department list in it as an array.
In Your COntroller file you will get all date on $data['dept'] that returned from model.
public function department()
{
$this->load->model('insert_model');
$data['dept'] = $this->insert_model->category_name_get();
$this->load->view('view_file_name',$data);
}
In your view file you will get this data
Just do print_r($dept); and check array..
you will find more info from this link
Probably your model is not returning "proper" data for your view. Perhaps something like this:
function category_name_get()
{
$data = array();
$query = $this->db->get('dept');
if ($query->num_rows >= 1)
{
foreach($query->result_array() as $row)
{
$data[] = array(
'dept_id' => $row['dept_id'],
'managers_name' => $row['managers_name']
);
}
}
return $data;
}
function category_name_get()
{
$query = $this->db->get('dept');
if ($query->num_rows() >= 1)
{
foreach($query->result_array() as $row)
{
$data[$row['dept_id']]=$row['managers_name'];
}
return $data;
}
}
Use num_rows() instead of num_rows. I hope it works now.
I'm trying to make alert with cross sign. Unfortunately cross sign not working. I have included jquery before bootstrap.js. Here is my model. Thanks in Advance
public function create(){
$data = array('name'=> $this->input->post('name'));
$this->db->insert('dbname', $data);
echo'
<div class="alert alert-success">
×You have successfully posted
</div>
';
exit;
}
Change this to
×You have successfully posted
this
×You have successfully posted
And as well as use Model to write data into database. Use follows
In controller
public function create(){
$this->load->model('Model_name');
$result = $this->Model_name->insert_data();
if($result == 1)
{
?>
<div class="alert alert-success">
×You have successfully posted
</div>
<?php
}
else
{
?>
<div class="alert alert-error">
×Failed to poste
</div>
<?php
}
}
In Model
public function insert_data()
{
$data = array(
'name'=> $this->input->post('name')
);
if(!$this->db->insert('dbname', $data))
{
return $log = 0;
}
else
{
return $log = 1;
}
}

In your Model code Registration_model , Else part assignment operator is wrong
change the following line
$dbRet-$this->db->insert('user', $data);
to
$dbRet = $this->db->insert('user', $data);
need help on this one:
here's a my sample code,
i would like to add a validation message if a preg_match occurs:
pls. see inline comments for more details..
public function supplier_entry()
{
if (preg_match("/[\'^£#&*...etc.../", $this->input->post('supplier')))
{
//add or pass validation message, ex. $msg = 'Invalid Supplier Name';
// i tried $this->supplier_entry_form($msg); but its not working.
$this->supplier_entry_form();
}else{
$post_data = array(
'supplier_name' =>$this->input->post('supplier'),
'user' => $this->input->post('user'),
'trx_id' =>$this->input->post('trx_id'),
);
$this->load->model('user_model');
$this->load->model('product_model');
$this->product_model->add_new_supplier($post_data);
$user_data['trx'] = 'Supplier Entry';
$user_data['username'] = $this->user_model->user_info();
$trx_data['supplier'] = $this->product_model->get_supplier_list();
$trx_data['msg'] = 'Supplier Posted.';
$this->load->view('header',$user_data);
$this->load->view('item_supplier', $trx_data);
}
}
thanks in advance..
public function supplier_entry_form()
{
$this->load->model('user_model');
$this->load->model('product_model');
$user_data['username'] = $this->user_model->user_info();
$user_data['trx'] = 'Supplier Entry';
$trx_data['supplier'] = $this->product_model->get_supplier_list();
$this->load->view('header', $user_data);
$this->load->view('item_supplier', $trx_data);
}
Use the built in form validation.
$this->load->library('form_validation');
$this->form_validation->set_rules($this->input->post('supplier'), 'Supplier', 'trim|callback_pregMatchSupplier');
if($this->form_validation->run()==FALSE)
{
$this->supplier_entry_from();
}
// continue code here if validation passes.
function pregMatchSupplier()
{
if (preg_match("/[\'^£#&*...etc.../", $this->input->post('supplier')))
{
return FALSE;
} else {
return TRUE;
}
Then in the view you echo out the validation errors:
<?php echo validation_errors(); ?>
