Codeigniter文件在上传时调整大小

I've been trying to upload and resize an image. The upload seems to be finally be working, but it's not resizing.

In my constructor I am loading the library

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

and then in my function I'm calling the the resize and upload

    $this->require_auth();      
    $img = $this->input->post('photo1');

    $config['upload_path'] = './HTML/files/';
    $config['file_name'] = 'photo1.jpg';
    $config['file_path'] = './HTML/files/photo1.jpg';
    $config['max-size'] = 2000;
    $config['image_library'] = 'gd2';
    $config['source_image'] = $config['file_path'];
    $config['create_thumb'] = TRUE;
    $config['maintain_ratio'] = FALSE;
    $config['width']    = 549;
    $config['height']   = 549;
    $config['overwrite'] = TRUE;
    $config['allowed_types'] = 'gif|jpg|png|jpeg';
    $config['new_image'] = $config['file_path'];
    $this->load->library('image_lib', $config); 
    $this->image_lib->resize();
    $this->load->library('upload', $config);                


    if ( ! $this->upload->do_upload('photo1')){        
       $error = array('error' => $this->upload->display_errors());
       var_dump($error);
     }else{
         $this->blog_model->editServiceImg1($config['file_path']); 
         redirect('/blog');
     }

I have also tried this

    $this->require_auth();      
    $img = $this->input->post('service_photo1');

    $config['upload_path'] = './HTML/files/';
    $config['file_name'] = 'service_photo1.jpg';
    $config['file_path'] = './HTML/files/service_photo1.jpg';
    $config['max-size'] = 2000;
    $config['overwrite'] = TRUE;
    $config['allowed_types'] = 'gif|jpg|png|jpeg';
    $this->load->library('upload', $config);                


    if ( ! $this->upload->do_upload('service_photo1')){        
       $error = array('error' => $this->upload->display_errors());
       var_dump($error);
     }else{
        $config['image_library'] = 'gd2';
        $config['source_image'] = $config['file_path'];
        $config['create_thumb'] = TRUE;
        $config['maintain_ratio'] = FALSE;
        $config['width']    = 549;
        $config['height']   = 549;
        $config['new_image'] = $config['file_path'];
        $this->image_lib->initialize($config);
        $this->image_lib->resize();


         $this->blog_model->editServiceImg1($config['file_path']); 
         redirect('/blog');
     }  

Is there something I'm missing? I've tried doing the resize after the initial upload as well and that seemed to do nothing as well. Any help would be much appreciated.

I went through this code many times and finally resolved this issue. It seems that when you have

$config['create_thumb'] = TRUE;

in your code it will create a thumbnail with the resized proportions and if you do not tell it where to go it will hide it in a folder. So the resizing was working, just not on the right image.

To resolve this, I changed the above to.

$config['create_thumb'] = FALSE;

$this->load->library('image_lib');
$config['image_library'] = 'gd2';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['upload_path'] = './HTML/files/';
$config['file_path'] = './HTML/files/photo1.jpg';
$config['source_image'] = $config['file_path'];
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width']     = 75;
$config['height']   = 50;

$this->image_lib->clear();
$this->image_lib->initialize($config);
$this->image_lib->resize();

If the above code won't work then please check the folder permissions where the images are upload.

You can also give 777 permission to the folder in following manner :-

sudo chmod -R 777 path

Solution will surely help you
