Image resize codeigniter issue not working - codeigniter

Question

I've been attempting to resize images but with no luck! I have the resize inside the upload function but not sure what is happening wrong! The code below shows my upload function (and resize within it):
function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '2048';
$this->load->library('image_lib', $config);
$this->load->library('upload', $config);
$fullImagePath = '';
if (! $this->upload->do_upload())
{
$this->upload->display_errors('<p style="color: maroon; font-size:large;">', '</p>');
$error = array('file_error' => $this->upload->display_errors());
// print_r($error);
$this->load->view('layout/header');
$this->load->view('add_gallery', $error);
$this->load->view('layout/footer');
}else{
//echo "UPLOAD SUCCESS";
// set a $_POST value for 'image' that we can use later
/*Image Manipulation Class*/
$config['image_library'] = 'gd2';
$config['source_image'] = $fullImagePath;
echo $fullImagePath;
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['max_width'] = '480';
$config['max_height'] = '640';
$this->load->library('image_lib', $config);
$this->image_lib->resize();
$upload_data = $this->upload->data();
$fullImagePath = '/uploads/' . $upload_data['file_name'];
}
return $fullImagePath;
}
The upload works fine and I get the fullImagePath (link) to store in database. ANyway, just not sure how to handle the resize.

Answer 1

The resize() function requires that you first have configured the source_image before calling it, so it can apply the resize to the specified image.
You are sending an empty path.
Here you declare the path as empty string $fullImagePath = ''; and then here you define it to the configuration options $config['source_image'] = $fullImagePath; and after that you call the $this->image_lib->resize(); , so it can not do resize to an empty image.
Also you are loading twice the image_lib which is not needed.
I modified your code. Test it and see if it works
function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '2048';
$this->load->library('upload', $config);
$fullImagePath = '';
if (! $this->upload->do_upload()){
$this->upload->display_errors('<p style="color: maroon; font-size:large;">', '</p>');
$error = array('file_error' => $this->upload->display_errors());
$this->load->view('layout/header');
$this->load->view('add_gallery', $error);
$this->load->view('layout/footer');
}else{
$upload_data = $this->upload->data();
$fullImagePath = '/uploads/' . $upload_data['file_name'];
$config['image_library'] = 'gd2';
$config['source_image'] = $fullImagePath;
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['max_width'] = '480';
$config['max_height'] = '640';
$config['width'] = 75;
$config['height'] = 50;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
}
return $fullImagePath;
}
