Display value in view - codeigniter

Question

In this codeigniter model i have this query testing if value entered in input exists in database..
function get_search_form() {
$match = $this->input->post('search1');
$this->db->where('numero',$match);
$this->db->where('inscris','non');
$q = $this->db->get('transaction');
if($q->num_rows()>0)
{
foreach($q->result() as $row)
{
$data[] = $row;
}
return $data;
}
}
Behold the controller i'd like to display value grabbed in input in view inscription.php
function search()
{
$data['row'] = $this->site_model->get_search_form();
$this->load->view('acceuil/aside');
$this->load->view('acceuil/inscription', $data);
}
My issue is how to display in that view input value and a form if this value exists in database ?
I have tried like this but i need help :
inscription view:
<?=form_open('navigation/search');?>
<input type="text" name="search1" id="search1" required />
<input type='submit' value='Display' />
<?=form_close();?>
I try to display the form like this but i don't know how to display as well the input value entered
<?php
if( $row > 0 )
{
?>
les champs du formulaire ici....
<?php
}else
{ }
?>

Answer 1

In your view you can check if the variable $row is not null (because it will be null when no rows are found):
if ($row !== null) {
// do stuff
}
You can modify the model function to return some other value if no rows are found, for example, by setting the $data to an empty array:
function get_search_form() {
$match = $this->input->post('search1');
$this->db->where('numero',$match);
$this->db->where('inscris','non');
$q = $this->db->get('transaction');
$data = array(); // <--- here
if($q->num_rows()>0)
{
foreach($q->result() as $row)
{
$data[] = $row;
}
return $data;
}
}
And then in the view you can simply loop the data:
foreach($row as $r) {
// do stuff
}
or you can implode the array to use as the input value:
<input type="text"
name="search1"
id="search1" required
value="<?php echo implode(' ', $row); ?>" />
You could also use html entities here, in case double quotes are possible to appear in what your model function returns (I have no idea what it returns).

Answer 2

you can access $data global object like this check
<?php
if( isset($row))
{
foreach($row as $v){
//Do the operations here
}
}else
{
//Do the operations here
}
?>
