Codeigniter - Two images upload did not work - php

Question

I tried to upload two images using a form. To do that I wrote a image function.
protected function imageUploadResize($filename, $field_name, $width, $height, $maker){
// thumb image upload settings
$config['upload_path'] = './uploads/packages/';
$config['allowed_types'] = 'gif|jpg|png';
// thumb upload settings
$image_new_name = time().'_'.$filename;
$config['file_name'] = $image_new_name;
$this->load->library('upload', $config);
// upload thumb image
if ( $this->upload->do_upload($field_name)) {
// resize uploaded file
$config['image_library'] = 'gd2';
$config['source_image'] = './uploads/packages/'.$image_new_name;
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = $width;
$config['height'] = $height;
$config['thumb_marker'] = $maker;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
$error = array('error' => $this->upload->display_errors());
} else {
$imageData = array('upload_data' => $this->upload->data());
}
return $image_new_name;
}
And I access that function this way,
// allocate image name to data set
if(!empty($_FILES["thumb_image"]['name'])){
// thumb upload
$thumb_image_new_name = $this->imageUploadResize($_FILES["thumb_image"]['name'],'thumb_image',THUMB_IMAGE_WIDTH, THUMB_IMAGE_HEIGHT, '_thumb');
$data['thumb_image'] = $thumb_image_new_name;
}else{
$data['thumb_image'] = "";
}
// allocate image name to data set
if(!empty($_FILES["banner_image"]['name'])){
// banner upload
$banner_image_new_name = $this->imageUploadResize($_FILES["banner_image"]['name'],'banner_image',BANNER_IMAGE_WIDTH, BANNER_IMAGE_HEIGHT, '_banner');
$data['banner_image'] = $banner_image_new_name;
}else{
$data['banner_image'] = "";
}
When I upload one image (thumb_image or banner_image) above function is worked properly.
But when I upload both images thumb_image uploaded properly but banner_image did not upload properly. As a example assume I am going to upload Hydrangeas.jpg and Desert.jpg. Then it is working this way,
Then file uploaded this way (images names of the folder),
1493025280_Hydrangeas.jpg
1493025280_Hydrangeas_thumb.jpg
1493025280_Hydrangeas1.jpg - image name also wrong
But expected output is (images names of the folder),
1493025280_Hydrangeas.jpg
1493025280_Hydrangeas_thumb.jpg
1493025280_Desert.jpg
1493025280_Desert_banner.jpg
Can someone please help me, thank you..

A different approach that i use for file uploads is below.
I rearrange the $_FILES array because the original has some difficulties with keys and objects.
$files = array();
foreach ($_FILES['files']['name'] as $num_key => $dummy) {
foreach ($_FILES['files'] as $txt_key => $dummy) {
$files[$num_key][$txt_key] = $_FILES['files'][$txt_key][$num_key];
}
}
In new array, loop through each image and do what you need:
foreach ($files as $file) {
if ($file['error'] == 0) {
//Your code here...
//Call your function imageUploadResize
}
}

Finally found the solution, In codeigniter when upload image, we have to call,
$this->load->library('upload', $config);
Then we have to initialized the configurations.
$this->upload->initialize($config);
And when resize image we have to call,
$this->load->library('image_lib', $config);
Then have to initialized the configurations.
$this->image_lib->initialize($config);
Therefore completed function is,
protected function imageUploadResize($filename, $field_name, $width, $height, $maker){
// thumb image upload settings
$config['upload_path'] = './uploads/packages/';
$config['allowed_types'] = 'gif|jpg|png';
// thumb upload settings
$image_new_name = time().'_'.$filename;
$config['file_name'] = $image_new_name;
$this->load->library('upload', $config);
$this->upload->initialize($config);
// upload thumb image
if ( $this->upload->do_upload($field_name)) {
// resize uploaded file
$config['image_library'] = 'gd2';
$config['source_image'] = './uploads/packages/'.$image_new_name;
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = $width;
$config['height'] = $height;
$config['thumb_marker'] = $maker;
$this->load->library('image_lib', $config);
$this->image_lib->initialize($config);
$this->image_lib->resize();
$error = array('error' => $this->upload->display_errors());
} else {
$imageData = array('upload_data' => $this->upload->data());
}
return $image_new_name;
}
