Codeigniter – photo upload with codeigniter

codeigniterimagephotoupload

I know there are many tutorials online, but I could not make them work 🙁 maybe something particularly wrong with my system :/

My Controller localpath is:
/localhost/rl/applications/backend/controller/

Controller:

function do_upload()
{
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '100';
    $config['max_width']  = '1024';
    $config['max_height']  = '768';

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

    if ( ! $this->upload->do_upload())
    {
        $error = array('error' => $this->upload->display_errors());

        $this->load->view('add_image', $error);
    }   
    else
    {
        $data = array('upload_data' => $this->upload->data());

        $data['id'] = $this->input->post['id_work'];
        $this->load->view('add_image', $data);
    }

}

My View localpath is:
/localhost/rl/applications/backend/view/

View:

echo form_open_multipart('do_upload');  
    <ul class="frm">
        <li><label>File: *</label><input type="file" name="userfile" class="frmlmnt" size="50" /></li>      
        <li><label></label><input type="submit" class="btn" value="Upload" /></li>
    </ul>
 </form>

Maybe I do something wrong with path

Change your view

echo form_open_multipart('backend/controllername/do_upload');

and create backend folder inside the controllers folder.

CodeIgniter Upload and Resize Problem

I'm not entirely sure what's going wrong with your code, but here's a model function I wrote for resizing images to fit an exact target height and target width. Read through it and see if you can't figure out the solution.

$this->prefix is a property in my class that I use so I don't have to keep writing out the directory of the file. It looks like this:

$this->prefix = FCPATH.'uploads'.DIRECTORY_SEPARATOR;

Image resizer

/**
 * Resizes an image to fit exact dimensions
 * 
 * @param string    filename
 * @param int      target_width
 * @param int      target_height
 * 
 * @return array('success' ? null : 'error')
 */
function resizeImageToDimensions($filename, $target_width=700, $target_height=399)
{
    $file_type = $this->getFileType($this->prefix.$filename);

    if (!$file_type || $file_type != 'image')
        return array('success'=>false, 'error'=>"This file doesn't exist or isn't an image");

    $this->load->library('image_lib');

    list($width, $height) = getimagesize($this->prefix.$filename);
    $current_ratio = $width/$height;
    $target_ratio = $target_width/$target_height;
    $config['source_image'] = $this->prefix.$filename;

    if ($current_ratio > $target_ratio)
    {
        //resize first to height, maintain ratio
        $config['height'] = $target_height;
        $config['width'] = $target_height * $current_ratio;
        $this->image_lib->initialize($config);

        if (!$this->image_lib->resize())
            return array('success'=>false, 'error'=>"There was an error while resizing this image");

        //then crop off width
        $config['width'] = $target_width;
        $config['maintain_ratio'] = false;
        $this->image_lib->initialize($config);

        if ($this->image_lib->crop())
            return array('success'=>true);
        else
            return array('success'=>false, 'error'=>"There was an error while cropping this image");
    }
    else if ($current_ratio < $target_ratio)
    {
        //resize first to width, maintain ratio
        $config['width'] = $target_width;
        $config['height'] = $target_width / $current_ratio;
        $this->image_lib->initialize($config);

        if (!$this->image_lib->resize())
            return array('success'=>false, 'error'=>"There was an error while resizing this image");

        //then crop off height
        $config['height'] = $target_height;
        $config['maintain_ratio'] = false;
        $this->image_lib->initialize($config);

        if ($this->image_lib->crop())
            return array('success'=>true);
        else
            return array('success'=>false, 'error'=>"There was an error while cropping this image");
    }
    else {
        $config['width'] = $target_width;
        $config['height'] = $target_height;
        $this->image_lib->initialize($config);

        if ($this->image_lib->resize())
            return array('success'=>true);
        else
            return array('success'=>false, 'error'=>"There was an error while resizing this image");
    }
}
