Creating an update function on my personal project would be glad if anyone can help.
This is the controller
public function update($id){
helper(['form']);
$model = new BlogModel();
$data = $model->find($id);
//echo $data['image'];
if ($this->request->getMethod() == 'post') {
$rules = [
'image' => 'is_image[image]',
'title' => 'required|min_length[3]|max_length[255]',
'body' => 'required',
];
$old_img = $data['image'];
$file=$this->request->getFile('image');
if ( $this->validate($rules)) {
if($file->isValid() && !$file->hasMoved())
{
if(file_exists("uploads/images/".$old_img)){
\unlink("uploads/images/".$old_img);
}
$imagename = $file->getRandomname();
$file->move('./uploads/images/', $imagename);
}
else{
$imagename = $old_img;
}
$newData = [
'title' => $this->request->getVar('title'),
'body' => $this->request->getVar('body'),
'slug' => url_title($this->request->getVar('title')),
'image' => $imagename
];
$model->update($id,$newData);
$session = \Config\Services::session();
$session->setFlashdata('success','Post was created Successfully');
return redirect()->to('/');
}else{
$data['validation'] = $this->validator;
}
}
