Codeigniter - How to upload original image with thumbnail image? - php

Question

I have this code to file upload in codeigniter:
if(!empty($_FILES['userfile'])){
$name_array = array();
$count = count($_FILES['userfile']['size']);
foreach($_FILES as $key => $value)
for ($s=0; $s<=$count-1; $s++){
$_FILES['userfile']['name'] = $value['name'][$s];
$_FILES['userfile']['type'] = $value['type'][$s];
$_FILES['userfile']['tmp_name'] = $value['tmp_name'][$s];
$_FILES['userfile']['error'] = $value['error'][$s];
$_FILES['userfile']['size'] = $value['size'][$s];
$config['upload_path'] = './public/images/campaign-images/';
$config['allowed_types'] = 'gif|jpg|jpeg|png|GIF|JPG|JPEG|PNG';
$config['max_size'] = '10000';
//$config['max_width'] = '1024';
//$config['max_height'] = '768';
$CI->load->library('upload', $config);
$CI->upload->do_upload();
$data = $CI->upload->data();
$name_array[] = $data['file_name'];
}
return $name_array;
}
This code is working perfect with single original image upload but how to upload image as thumbnail image(350 x 250) with resize in different folder.
Any idea how to do with codeigniter library?
Thanks

Answer 1

First store the original image and afterwards thumbnail image will upload
You just need to include gd2 library to generate the thumbnail image
if(!empty($_FILES['userfile'])){
$name_array = array();
$count = count($_FILES['userfile']['size']);
foreach($_FILES as $key => $value)
for ($s=0; $s<=$count-1; $s++)
{
//Original Image Upload - Start
$_FILES['userfile']['name'] = $value['name'][$s];
$_FILES['userfile']['type'] = $value['type'][$s];
$_FILES['userfile']['tmp_name'] = $value['tmp_name'][$s];
$_FILES['userfile']['error'] = $value['error'][$s];
$_FILES['userfile']['size'] = $value['size'][$s];
$config['upload_path'] = './public/images/campaign-images/';
$config['allowed_types'] = 'gif|jpg|jpeg|png|GIF|JPG|JPEG|PNG';
$config['max_size'] = '10000';
//$config['max_width'] = '1024';
//$config['max_height'] = '768';
$CI->load->library('upload', $config);
$CI->upload->do_upload();
$data = $CI->upload->data();
//Original Image Upload - End
//Thumbnail Image Upload - Start
$config['image_library'] = 'gd2';
$config['source_image'] = './public/images/campaign-images/'. $value['name'][$s];
$config['new_image'] = './public/images/campaign-images/thumbs/'.$value['name'][$s];
$config['width'] = 350;
$config['height'] = 250;
//load resize library
$this->load->library('image_lib', $config);
$this->image_lib->resize();
//Thumbnail Image Upload - End
$name_array[] = $data['file_name'];
}
return $name_array;
}

//Original Size of Image Upload - End
//Thumbnail Size of Image Upload - Start

$config['source_image'] = 'PATH_TO_IMAGE_UPLOAD'. $value['name'][$s];
$config['new_image'] = 'PATH_TO_UPLOAD_THUMB_IMAGE'.$value['name'][$s];
$config['width'] = 350;
$config['height'] = 250;
//CI load resize library
$this->load->library('image_lib', $config);
$this->image_lib->resize();
//Thumbnail SIZED Image Upload - End
$name_array[] = $data['file_name'];
}
return $name_array;
