display query result after inserting - php

Question

please help me how to display data to the view page after insert query into database.
view page(member_view.php):
<form action="<?php member_controller/insert_info; ?>" method="post">
<input type="text" name="fname">
<input type="text" name="lname">
<input type="submit" name="submit">
</form>
<?php
if($res){
foreach($res as $data){
echo $data['fname'];
echo $data['lname'];
}
}
?>
controller page(member_controller.php):
<?php
class Member_Controller extends CI_Controller {
public function insert_info(){
$data = array('fname' => $this->input->post('fname'),
'lname' => $this->input->post('lname'),
);
$this->load->model('member_model');
$this->member_model->member_posting($data);
$data['username'] = $session_data['username'];
$retrieved_info['res'] = $this->member_model->member_posting($data);
$this->load->view('member_view',$data, $retrieved_info)
}
}
model page(member_model):
<?php
class Member_Model extends CI_Model{
public function member_posting($data=array()){
extract($data);
$query = "INSERT INTO member_table (fname, lname)values ('$fname', '$lname')";
$result = $this->db->conn_id->prepare($query);
$result->execute();
if($result){
$query = "SELECT * FROM member_table WHERE fname = '$fname' AND lname='$lname'";
$result = $this->db->conn_id->prepare($query);
$result->execute();
return $res = $result->fetchAll(PDO::FETCH_ASSOC);
}
}
}
and here would be the pattern:
view(submit form)---->controller(get vars and send to model) --->
model(insert to db and perform select query)--->controller(get the select query results from model)--->view(display the results)
please help me, im just new to codeigniter, hope i can learn from you guys.

Answer 1

This is the way you need to follow.........
View file:member_view.php
<form action="<?php echo ROOT_FOLDER ?>/member_controller/insert_info" method="post">
<input type="text" name="fname">
<input type="text" name="lname">
<input type="submit" name="submit">
</form>
Controller file: member_controller.php
<?php
class Member_Controller extends CI_Controller {
public function insert_info()
{
$data = array(
'fname' => $this->input->post('fname'),
'lname' => $this->input->post('lname'),
);
$this->load->model('member_model');
$this->member_model1->member_posting($data);
$retrieved_info = array();
$retrieved_info['res'] = $this->member_model2->member_posting($data);
$this->load->view('member_view',$data, $retrieved_info)
}
}
Model file: member_model1.php
class Member_Model extends CI_Model{
public function member_posting_inserting($data){
$this->insert_helper('member_table',$data);
}
public function member_posting_retrieving($data){
$query = "SELECT * FROM member_table WHERE fname = '$data['fname']' AND lname='$data['lname']'";
$res=$this->db->query($query);
if($res->num_rows()>0){
return $res->result("array");
}
return array();
}
}
Insert helper function...............
public function insert_helper($table_name, $data_array){
$this->db->insert($table_name,$data_array);
return $this->db->insert_id();
}

Answer 2

This
$this->load->view('member_view',$data, $retrieved_info)
in your case won't do the trick. Read about the views here: http://ellislab.com/codeigniter/user-guide/general/views.html
2nd parameter is data array. 3rd parameter can be TRUE or FALSE, deciding if the view has to be rendered or returned as string.
This should do the trick:
$this->load->view('member_view', $retrieved_info);
Edit:
Just noticed your member_posting() doesn't return anything. It should return $res;
