Codeigniter文件上传和调整大小 [英] Codeigniter file upload and resize

问题描述

我将个人资料照片上传到我的网站，第一个上传工作正常，但是当我尝试调整图像大小并将其重新上传到同一个文件夹时，就会中断。从测试中，我知道这是通过数组，并将数据插入到数据库，但不是重新保存到文件夹中。

这是我有一个。

  $ config ['upload_path'] ='./uploads/'; 
 $ config ['file_name'] = $ this-> user-> pen_name。'。jpg'; 
 $ config ['file_path'] ='./uploads/'.$this-> user-> ;pen_name.'.jpg'; 
 $ config ['max-size'] = 2000; 
 $ config ['overwrite'] = TRUE; 
 $ config ['allowed_types'] ='gif | jpg | png | jpeg'; 
 $ config ['remove_spaces'] = true; 
 $ config ['max_width'] = 2000; 
 $ config ['max_height'] = 3000; 
 $ this-> load->库（'upload'，$ config）; 
 $ b $ if（！$ this-> upload-> do_upload（））{
 
 $ error = array（'error'=> $ this-> upload - >的display_errors（））; 
} else {
 $ resize ['source_image'] = base_url（）。'/ uploads /'.$ config ['file_name']; 
 $ resize ['new_image'] ='./uploads/'; 
 $ resize ['file_path'] ='./uploads/'.$this-> user-> ;pen_name.'.jpg'; 
 $ resize ['create_thumb'] = false; 
 $ resize ['maintain_ratio'] = true; 
 $ resize ['width'] = 200; 
 $ resize ['height'] = 300; 
 $ resize ['overwrite'] = TRUE; 
 $ this-> load->库（'image_lib'，$ resize）; 
 $ this-> image_lib-> resize（）; 
 $ this-> load->库（'upload'，$ resize）; 
 $ this-> users_model-> uploadPic（$ resize ['file_path']）; 
重定向（$ _ SERVER ['HTTP_REFERER']）; 
 
 $ / code> 

任何帮助都会非常感谢！

I'm uploading profile pictures to my website and the first upload is working fine, but when I try and resize the image and reupload it to the same folder it breaks. From testing, I know it is going through the array and it is inserting the data into the database, but just not re-saving into the folder.

This is what I have going one.

$config['upload_path'] = './uploads/';
$config['file_name'] = $this->user->pen_name.'.jpg';
$config['file_path'] = './uploads/'.$this->user->pen_name.'.jpg';
$config['max-size'] = 2000;
$config['overwrite'] = TRUE;
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['remove_spaces'] = true;
$config['max_width'] = 2000;
$config['max_height'] = 3000;
$this->load->library('upload', $config);

if ( ! $this->upload->do_upload()){

        $error = array('error' => $this->upload->display_errors());
}else{
    $resize['source_image'] = base_url().'/uploads/'.$config['file_name'];
    $resize['new_image'] = './uploads/';
    $resize['file_path'] = './uploads/'.$this->user->pen_name.'.jpg';
    $resize['create_thumb'] = false;
    $resize['maintain_ratio'] = true;
    $resize['width'] = 200;
    $resize['height'] = 300;
    $resize['overwrite'] = TRUE;
    $this->load->library('image_lib', $resize);
    $this->image_lib->resize();
    $this->load->library('upload', $resize);
    $this->users_model->uploadPic($resize['file_path']);
    redirect($_SERVER['HTTP_REFERER']);
}

Any help would be much appreciated!

解决方案

Just had the same issue, and solved it as follows:

    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png|jpeg';
    $config['max_size'] = '2048';
    $config['encrypt_name'] = TRUE;
    $this->load->library('upload', $config);

    if (!$this->upload->do_upload('logoUpload')) {
        $this->data['error'] = array('error' => $this->upload->display_errors('<div class="alert alert-danger">', '</div>'));
        //error
    } else {

        $upload_data = $this->upload->data();

        //resize:

        $config['image_library'] = 'gd2';
        $config['source_image'] = $upload_data['full_path'];
        $config['maintain_ratio'] = TRUE;
        $config['width']     = 150;
        $config['height']   = 50;

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

        $this->image_lib->resize();

        //add to the DB
        $this->settings_model->upload_logo($upload_data);
