[FIXED] How to compress an image with codeigniter image_lib?

Issue

I am trying to compress size of the image in my codeigniter php website and wrote the following code in my controller:

$this->load->library('image_lib');
$this->load->library('upload');
$image = array();
$ImageCount = count($_FILES['pimage']['name']);
for($i = 0; $i < $ImageCount; $i++){
    $_FILES['file']['name']       = $_FILES['pimage']['name'][$i];
    $_FILES['file']['type']       = $_FILES['pimage']['type'][$i];
    $_FILES['file']['tmp_name']   = $_FILES['pimage']['tmp_name'][$i];
    $_FILES['file']['error']      = $_FILES['pimage']['error'][$i];
    $_FILES['file']['size']       = $_FILES['pimage']['size'][$i];
    
    // File upload configuration
    $uploadPath = './uploads/products/';
    $config['image_library'] = 'gd2';
    
    $config['upload_path'] = $uploadPath;
    $config['allowed_types'] = 'jpg|jpeg|png|gif';
    $config['quality'] = '60%';
    
    // Load and initialize upload library
    $this->load->library('upload', $config);
    $this->upload->initialize($config);
    
    // Upload file to server
    if($this->upload->do_upload('file')){
        // Uploaded file data
        $imageData = $this->upload->data();
        // $uploadImgData[$i]['image_name'] = $imageData['file_name'];
        $uploadImgData[] = $imageData['file_name'];
    }
}

but after upload the image is still saved in the same size, can anyone please tell me what is wrong in here?

Solution

You need to pair the config setting with a library action like resize (R), cropping (C), rotation (X) or watermark (W).

see Processing Methods

and Preferences:

Preference	Default Value	Options	Description	Availability
quality	90%	1 - 100%	Sets the quality of the image. The higher the quality the larger the file size.	R, C, X, W

At the moment you are just setting a bunch of config data and upload the image without a processing method, hence nothing is changed.
