SQL Query with specific ID/row on Codeigniter - php

Question

I need to print my data with specific ID by using SELECT * FROM query and I have problem with my query.
Example, i have table called tb_pasien , and it has 8 columns :
kode_pasien(as ID), nama_pasien, email_pasien, alamat_pasien, tanggal_lahir, umur, jenis_kelamin and no_telp.
So, when I want to print someone data it will only show her/his data not all data on my table.
This is my code :
Model
public function view_kartu()
{
$query = $this->db->query("SELECT * FROM tb_pasien where kode_pasien='$kode_pasien' LIMIT 1");
return $query;
}
Controller
public function cetakkartu() {
// Load all views as normal
$data['pasien'] = $this->a_model->view_kartu();
$this->load->view('cetak-kartu', $data);
// Get output html
$html = $this->output->get_output();
// Load library
$this->load->library('dompdf_gen');
// Convert to PDF
$this->dompdf->load_html($html);
$this->dompdf->render();
$this->dompdf->stream("cetak-kartu" . ".pdf", array ('Attachment' => 0));
}
View
<table border="1" width="100%">
<tr>
<th>Kode Pasien</th>
<th>Nama Pasien</th>
<th>Email Pasien</th>
<th>Alamat Pasien</th>
<th>Tanggal Lahir</th>
<th>Umur</th>
<th>JK</th>
<th>No. Telp</th>
</tr>
<?php
if( ! empty($pasien)){
foreach($pasien as $data){
echo "<tr>";
echo "<td>".$data->kode_pasien."</td>";
echo "<td>".$data->nama_pasien."</td>";
echo "<td>".$data->email_pasien."</td>";
echo "<td>".$data->alamat_pasien."</td>";
echo "<td>".$data->tanggal_lahir."</td>";
echo "<td>".$data->umur."</td>";
echo "<td>".$data->kode_jk."</td>";
echo "<td>".$data->no_telp."</td>";
echo "</tr>";
}
}
?>
</table>
But when i try to print it, it shows empty result. Can someone help me? Thankyou.

Answer 1

Need to the return result array or row but not query (as per your requirement of fetching data from array or array object)
Like this
return $query->result_array();
or
return $query->row();

Answer 2

Try changing your model function as below -
public function view_kartu($kode_paisen)
{
$query = $this->db->query("SELECT * FROM tb_pasien where kode_pasien='$kode_pasien' LIMIT 1");
return $query;
}
And then from your controller, call it as -
public function cetakkartu() {
//set a value for $kode_paisen
$kode_paisen = "XXX"; //set here whatever you like.
// Load all views as normal . See here we passing the variabke in the function.
$data['pasien'] = $this->a_model->view_kartu($kode_paisen);
// Rest of your function ...
}
As an example, i have a table "currency" in my site and this is how i fetch all the currencies mapped to a particular company in Code Igniter model.
function getCurrencyList($companyId)
{
$sql = "select currency_id from company_currency where company_id = $companyId";
$retVal = $this->db->query($sql);
if($this->db->affected_rows() == 0)
{
return null;
}
if($retVal && $this->db->affected_rows() > -1)
{
if($retVal->result_array())
{
foreach($retVal->result_array() as $row)
{
$arrCurrencyId[] = $row['currency_id'];
}
}
return $arrCurrencyId;
}
else
{
log_message('error', mysql_error()." ******* at function getActionList Role Model *********");
return null;
}
}
I hope this will help you

try this query:
$this->db->select('kode_pasien as ID, nama_pasien, email_pasien, alamat_pasien, tanggal_lahir, umur, jenis_kelamin, no_telp');
$this->db->from('tb_pasien');
$data= $this->db->get()->result_array();
echo "<pre>"; print_r($data);die;
