Codeigniter - Get_where base from session_userdata - php

Question

I want to select all the rows that emp id's are match to my session userdata (emp_id). Here's my code. I get so many errors and no row has been selected. Someone help me please. Thanks
Model:
public function get_save_samp($emp_id) {
$query = $this->db->get_where('tblsavesample', array('emp_id' =>
$emp_id));
return $query->row_array();
}
Controller:
public function show() {
$emp_id = $this->session->userdata('emp_id');
$data['save'] = $this->user_model->get_save_samp($emp_id);
$this->load->view('show',$data);
}
Views:
<?php foreach ($save as $row) { ?>
<td style="width: " ><?php echo $row->emp_id ?></td>
<td style="width: " ><?php echo $row->emp_code?></td>
<td style="width: " ><?php echo $row->emp_name ?></td>
<?php }>

Try This
public function get_save_samp($emp_id) {
$query = $this->db->get_where('tblsavesample', array('emp_id' =>
$emp_id));
return $query->result();
}

Answer 2

you can try solution for your problem :
Changes your modal function :
Modal.php
public function get_save_samp($emp_id) {
$this->db->select("*");
$this->db->where('id', $emp_id);
$this->db->get('tblsavesample');
return $query->row();
}
Views:
<?php foreach ($save as $row) {?>
<td style="width: " ><?php echo $row->emp_id ?></td>
<td style="width: " ><?php echo $row->emp_code ?></td>
<td style="width: " ><?php echo $row->emp_name ?></td>
<?php } ?>

Answer 3

row_array() returns the first row only. If you want all the records to be returned, use result_array() instead.
$result = $query->result_array();
return $result;

Answer 4

Change your Modal Code like this :
public function get_save_samp($emp_id) {
//$query = $this->db->get_where('tblsavesample', array('emp_id' =>$emp_id));
$this->db->select("*");
$this->db->where_in('id', $emp_id);
$query = $this->db->get('tblsavesample');
return $query->result();
}
And Change your Controller code like this to check what data are we getting inside controller.
public function show()
{
$emp_id = $this->session->userdata('emp_id');
$data['save'] = $this->user_model->get_save_samp($emp_id);
echo "<pre>";
print_R($data['save']);
exit();
$this->load->view('show', $data);
}

Answer 5

row_array() used to return only single record. change your code in model as follows :
public function get_save_samp($emp_id) {
$query = $this->db->get_where('tblsavesample', array('emp_id' =>
$emp_id));
return $query->result_array();
}
and check number of records returned in your controller as follows:
$data['save'] = $this->user_model->get_save_samp($emp_id);
echo $data['save']->num_rows();
if this displays 0, then you have no matching records in your database table.
