How to change image name in multiupload with CodeIgniter? - php

Question

I want to change image names when uploading more than one image. I have tried to use this config but it doesn't work $config['file_name'] = $this->getRandomString(); So, I need help with this
function addProductPhotoGallery() {
if ($this->session->userdata('admin_login')) {
$this->load->model('admin/admin_model');
$gallery_photo = array();
$gallery_path = realpath(APPPATH . '../imgs/product_pic/');
$config1['upload_path'] = $gallery_path;
$config1['allowed_types'] = 'gif|jpg|png|jpeg|bmp';
$config1['max_size'] = '2000';
$this->load->library('upload', $config1);
$this->upload->initialize($config1);
$thum_path = realpath(APPPATH . '../imgs/product_pic/thumbs');
$config = array(
'image_library' => 'gd2',
'source_image' => '',
'maintain_ratio' => TRUE,
'width' => 300,
'height' => 200,
'new_image' => $thum_path
);
$this->load->library('image_lib', $config);
///////////// for loop and code that upload photo /////////////////////
$i = 1;
foreach ($_FILES as $filey) {
if (isset($_FILES['file' . $i])) {
$config['file_name'] = $this->input->post('username').$this->getRandomString();
// $_FILES['file' . $i]['name'] = $this->input->post('username').$this->getRandomString();
if($this->upload->do_upload('file' . $i)){
$phot_data = $this->upload->data();
$gallery_photo[$i] = $phot_data['file_name'];
$config['source_image'] = $phot_data['full_path'];
$this->image_lib->initialize($config);
$this->image_lib->resize();
$i++;
}else{
break;
return false;
}
}
}
return serialize($gallery_photo);
} else {
redirect('civou/home');
}
}

Try to putting $this->image_lib->clear()
after $this->image_lib->resize() so that on the next loop the/a new $config['file_name'] is used.
