Delete multiple image from database also database using codeigniter - php

Question

I just created code that deletes an image from database and also from folder which is an image store, but only one image is successfully deleted from thedatabase and folder when I click "check all". What did I do wrong? Here is my view using check box javascript:
<form name="indonesia" action="<?php echo site_url('admin/wallpaper/delete'); ?>" method="post">
<button type="submit" class="btn btn-danger" name="hapus" value="hapus">Hapus</button>
<?php echo anchor('admin/wallpaper/tambah', 'Tambah Wallpaper');?>
<table id="example" class="table table-striped table-bordered" cellspacing="0" width="100%">
<thead>
<tr>
<th>
<button type="button" class="btn btn-info" onClick="check_all()" >Check</button>
<button type="button" class="btn btn-success" onClick="uncheck_all()" >Un-Check</button>
</th>
<th>id</th>
<th>Keterangan</th>
<th>Gambar</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<?php
foreach ($ListWallpaper->result() as $row)
{
?>
<tr>
<td><input type="checkbox" name="item[]" id="item[]" value="<?=$row->id_wall ?>"></td>
<td><?=$row->id_wall ?></td>
<td><?=$row->ket ?></td>
<td><?=$row->wall ?></td>
<td>
Delete
Update
</td>
</tr>
<?php } ?>
</tbody>
</table>
</form>
and here is my controller
public function delete()
{
$ownerNames = $this->input->post('item');
foreach ($ownerNames as $ownerName => $k) {
//echo "Array : " . $k . "<br/>";
$photo = $this->wallpaper_model->del_photo($k);
if ($photo->num_rows() > 0)
{
$row = $photo->row();
$file_photo = $row->wall;
echo "$file_name</br>";
$path_file = 'image/wallpaper/';
unlink($path_file.$file_photo);
}
$this->wallpaper_model->drop_photo($k);
redirect('admin/wallpaper','refresh');
}
}
and my model
function del_photo($k)
{
$this->db->where('id_wall',$k);
$query = $getData = $this->db->get('tabel_wall');
if($getData->num_rows() > 0)
return $query;
else
return null;
}
function drop_photo($k)
{
$this->db->where('id_wall',$k);
$this->db->delete('tabel_wall');
}
Only one image is successfully deleted from the folder and database too, but when I try to echo "$file_name</br>"; it show all images. What did I do wrong? if anyone can guide me, I will appreciate that.

First off I would set a array of images from controller to view, $data['wallpapers'] = array(); for some of the site_url you may need to include in your route.php $route['controller/update/(:any)'] = "controller/update/$1"
To Delete selected images, You could do a selected post in array() and then on the value check box name=""
Disclaimer: This is just for a example only.
public function index() {
$k = $this->uri->segment(what ever); // Use uri segment is id example.com/image/1 = $this->uri->segment(2);
$results = $this->model_name->del_photo($k);
$data['wallpapers'] = array();
foreach ($results as $result) {
$data['wallpapers'][] = array(
'id_wall' => $result['id_wall'],
'update' => site_url('controllername/update' .'/'. $result['wall_id']),
'ket' => $result['ket']
);
}
$data['delete'] = site_url('controller/function');
$selected = $this->input->post('selected');
if (isset($selected)) {
$data['selected'] = (array)$selected;
} else {
$data['selected'] = array();
}
$this->load->view('your list', $data);
}
public function update() {
//update info here
}
public function delete() {
$selected = $this->input->post('selected');
if (isset($selected)) {
foreach ($selected as $image_id) {
$wall_id = $image_id
$this->db->query("DELETE FROM " . $this->db->dbprfix . "TABLENAME WHERE wall_id = '" . (int)$wall_id . "'");
}
}
}
View
Added echo delete from controller as site url.
<form action="<?php echo $delete;?>" method="post">
<table>
<thead>
<tr>
<td style="width: 1px;" class="text-center"><input type="checkbox" onclick="$('input[name*=\'selected\']').prop('checked', this.checked);" /></td>
<td>Update</td>
</tr>
</thead>
<tbody>
<?php if ($wallpapers) { ?>
<?php foreach ($wallpapers as $wallpaper) { ?>
<td class="text-center"><?php if (in_array($wallpaper['id_wall'], $selected)) { ?>
<input type="checkbox" name="selected[]" value="<?php echo $wallpaper['id_wall']; ?>" checked="checked" />
<?php } else { ?>
<input type="checkbox" name="selected[]" value="<?php echo $wallpaper['id_wall']; ?>" />
<?php } ?>
</td>
<td>Update</td>
<?php } ?>
<?php } ?>
</tbody>
</table>
</form>
Model
function del_photo($k) {
$this->db->where('id_wall',$k);
$query = $this->db->get('table_name');
if($query->num_rows() > 0) {
$return = $query->result_array();
} else {
return false;
}
}

In controller, move redirect directive outside of foreach loop.
