how to delete a row in database using codeigniter - php

Question

hye, i'm trying to do 'delete function' for my modul. i've tried so many different ways for this. but it come out no result, some come with error.
this is my controller (named expert.php) :
public function remove() {
$siri = $this->uri->segment(3);
$this->Kepakaran_m->delete($siri);
$this->view();
}
siri is the a field name (column name) in my table. it it primary key.
this is my model (named Kepakaran_m.php):
function delete($siri) {
$this->dbsmk->where('siri', $siri);
$this->dbsmk->delete('kexpt003pakar');
if ($this->dbsmk->affected_rows() == 1) {
return TRUE;
}
return FALSE;
}
kexpt003pakar is the table name.
so my view is this (named kepakaran.php):
<tbody>
<?php if(empty($kepakaran)) { ?>
<tr>
<td colspan="8">Pengguna tidak mempunyai rekod kepakaran!</td>
</tr>
<?php } else {
$num = 0;
foreach ($kepakaran as $list_kepakaran) {
$num++;
?>
<tr>
<td><?php echo $num; ?></td>
<td><?php echo $list_kepakaran->kategori; ?></td>
<td><?php echo $list_kepakaran->bidang; ?></td>
<td><?php echo $list_kepakaran->spesifik; ?></td>
<!-- untuk keluarkan tahap -->
<td><?php
if($list_kepakaran->tahap=='1'){
echo "Sederhana";
}elseif ($list_kepakaran->tahap=='2') {
echo "Tinggi";
}elseif ($list_kepakaran->tahap=='3') {
echo "Sangat Tinggi";
}
?>
</td>
<!-- done untuk keluarkan tahap -->
<td><?php echo $list_kepakaran->biltahun; ?></td>
<td>
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#tambahkepakaran"><i class="glyphicon glyphicon-pencil"></i></button>
<i class="glyphicon glyphicon-trash"></i>
</td>
</tr>
<?php }} ?>
</tbody>
so the delete button is in this area >>siri; ?>" type="button".....
i hope your answer will help me to discover this up. thank you :)

Answer 1

What's the error? I think you just need to modify your codes becomes:
<i class="glyphicon glyphicon-trash"></i>
Then it should be ok.
In order to use uri segment..do not forget to call url helper in autoload.php

english is not my native language.
For solve your problem, you can check a lot of things.
Did you forget to load model in your controller ?
Try to dump value of $siri in your remove function and show response on your network tab in chrome devTools for example.
If you don't call your controller, look at side of your href or open Application/config/routes.php for use routing and add this $route['expert/remove/(:num)']['GET'] = "expert/remove/$1";
If $siri is empty look at the side of $this->uri->segment(3);
Verify if you load correctly the helper.
For that, go to Application/config/autoload.php and see if url is in helper $autoload['helper'] = array('url','security','language', 'form', 'text');
