Multiple Image Upload and Resize Image In CodeIgniter

First you must load “image_lib” library of CI.

This is a controller in CI

public function imageUpload()
{
$data = array();
if ($this->input->post('submit'))
{
if ($_FILES["sc_name"]["name"])
{
$path = './upload_image';
if (!is_dir($path))
mkdir($path, 0755);

$pathMain = './upload_image/source';
if (!is_dir($pathMain))
mkdir($pathMain, 0755);

$pathThumb = './upload_image/100X100';
if (!is_dir($pathThumb))
mkdir($pathThumb, 0755);

$path2Thumb = './upload_image/200X200';
if (!is_dir($path2Thumb))
mkdir($path2Thumb, 0755);

$path3Thumb = './upload_image/300X300';
if (!is_dir($path3Thumb))
mkdir($path3Thumb, 0755);

$path4Thumb = './upload_image/400X400';
if (!is_dir($path4Thumb))
mkdir($path4Thumb, 0755);

$result = $this->do_upload("sc_name", $pathMain);

if (!$result['status'])
$data['error_msg'] ="Can not upload Image for " . $result['error'] . " ";
else
{
$pathThumb = './upload_image/100X100';
if (!is_dir($pathThumb))
mkdir($pathThumb, 0755);

//in other folder
if($this->resize_image($pathMain . '/' . $result['upload_data']['file_name'], $pathThumb . '/'.time().'100X100.gif','100','100'))
echo 'Image 100X100 resize done';
else
echo 'Image 100X100 resize failed';
if($this->resize_image($pathMain . '/' . $result['upload_data']['file_name'], $path2Thumb . '/'.time().'200X200.gif','200','200'))
echo 'Image 200X200 resize done';
else
echo 'Image 200X200 resize failed';
if($this->resize_image($pathMain . '/' . $result['upload_data']['file_name'], $path3Thumb . '/'.time().'300X300.gif','300','300'))
echo 'Image 300X300 resize done';
else
echo 'Image 300X300 resize failed';

//in same folder

if($this->resize_image($pathMain . '/' . $result['upload_data']['file_name'], time().'100X100.gif','100','100'))
echo 'Image 100X100 Same Folder resize done';
else
echo 'Image 100X100 Same Folder resize failed';
if($this->resize_image($pathMain . '/' . $result['upload_data']['file_name'], time().'200X200.gif','200','200'))
echo 'Image 200X200 Same Folder resize done';
else
echo 'Image 200X200 Same Folder resize failed';
if($this->resize_image($pathMain . '/' . $result['upload_data']['file_name'], time().'300X300.gif','300','300'))
echo 'Image 300X300 Same Folder resize done';
else
echo 'Image 300X300 Same Folder resize failed';

}
}
}

$this->load->view('sc/upload_image', $data);
}

Upload Function inside the CI Controller

function do_upload($htmlFieldName, $path)

{

        $config['file_name'] = time();

        $config['upload_path'] = $path;

        $config['allowed_types'] = 'gif|jpg|png';

        $config['max_size'] = '2000';

        $config['max_width'] = '2000';

        $config['max_height'] = '2000';

        $this->load->library('upload', $config);

        $this->upload->initialize($config);

        unset($config);

        if (!$this->upload->do_upload($htmlFieldName))

{

            return array('error' => $this->upload->display_errors(), 'status' => 0);

        } else

{

            return array('status' => 1, 'upload_data' => $this->upload->data());

}

}


Resize Function inside the CI Controller




function resize_image($sourcePath, $desPath, $width = '500', $height = '500')
    {
        $this->image_lib->clear();
        $config['image_library'] = 'gd2';
        $config['source_image'] = $sourcePath;
        $config['new_image'] = $desPath;
        $config['quality'] = '100%';
        $config['create_thumb'] = TRUE;
        $config['maintain_ratio'] = true;
        $config['thumb_marker'] = '';
        $config['width'] = $width;
        $config['height'] = $height;
        $this->image_lib->initialize($config);
 
        if ($this->image_lib->resize())
            return true;
        return false;
    }





And Finally The form in View

<?php echo form_open_multipart() ?>

 

<label for="sc_name">Name</label>

<input type="file" name="sc_name" /><br />

<input type="submit" name="submit" value="Create" />
