Image resize + upload

[eluser]clintonbeattie[/eluser]
Hi,

I am rushed with an app I have to build, otherwise I would have tried to attempt this myself, but I was wondering if anyone has detailed code for uploading an image, adding it's url to a database and creating a resized thumbnail?

A lot to ask for I know. Any help much appreciated.

Thanks,
C

I have written Auto resize image last month. I have added this function to CI but I can not find. Here is PHP code;

Code:

<?php
/**
* @author PCoder
* @copyright 2009
* Auto Resized Image / Thumb
*/
function resize($dosya, $yukseklik, $genislik, $kalite)
{
    $boyut = GetImageSize($dosya);
     /* Get image Width and Height */
    $resim_genis = $boyut[0];
     /* Real image width */
    $resim_yuksek = $boyut[1];
     /* Real image height */
    if ($resim_genis > $resim_yuksek) {
         /* If width is bigger than height */
        $yeni_y = ceil(($genislik * $resim_yuksek) / $resim_genis);
        $yeni_x = $yukseklik;
    } else {
         /* If height is bigger than width */
        $yeni_y = ceil(($yukseklik * $resim_genis) / $resim_yuksek);
        $yeni_x = $genislik;
    }
    $image_p = imagecreatetruecolor($yeni_x, $yeni_y);
     /* Create image with new size */
    $image = imagecreatefromjpeg($dosya);
     /* Load file from server that defined */
    imagecopyresampled($image_p, $image, 0, 0, 0, 0, $yeni_x, $yeni_y, $resim_genis,
        $resim_yuksek);
     /* Entegret the new sized image with loaded file */
    imagejpeg($image_p, null, $kalite);
     /* Create JPG file */
    Header("Content-type: image/jpeg");
     /* Some browser don't display image, this header() function fix */
}
?>

and Here is function to use;

Code:

<?php
resize("logo.jpg",150,150,90);
?>

I hope, I can help.

You should have a look at the Image Manipulation Class and the File Uploading Class.

It does all you want with little code.

This tutorial was on Nettuts recently, although it doesn't create thumbnails for you:

Here's a script I've been working on.... bits and peices are pulled out, but you'll get the point. Most of it can be found in the user guide

Also note - to get my script working, I had to use a hack that cwt137 kindly submitted.

This is the controller:

Code:

class Upload extends Controller
{
function do_upload()
    {
        // Image configuration
        $config['upload_path'] = './uploads/';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['overwrite'] = FALSE;
        $config['max_size'] = 2048;
        
        $this->load->library('upload', $config);
        
    
        if(!$this->upload->do_upload())
        {
            $error = array('error' => $this->upload->display_errors());
            $this->load->view('upload_form', $error);
        }
        else
        {
            
        
            $image = $this->upload->data();
            $data['image'] = "./uploads/".$image['file_name'];
            
            $config['image_library'] = 'gd2';
            $config['source_image'] = $data['image'];
            $config['create_thumb'] = TRUE;
            $config['maintain_ratio'] = TRUE;
            $config['width'] = 75;
            $config['new_image'] = "./uploads/".$image['file_name'];
            
            $this->load->library('image_lib', $config);
            
            $this->image_lib->resize();
            
            $data = array('upload_data' => $this->upload->data());
            
            $this->load->view('upload_success', $data);
            
        }
    }
}

the view is simply a form with an action that posts to do_upload

Code:

<?=form_open_multipart('admin/upload/do_upload');?>
