Question

A PHP Error was encountered

Severity: Notice Message:

我的代码:

Controller

public function do_upload(){
    $this->upload->do_upload();
    if($this->upload_model->Doupload()){
        echo 1;
    }else{
        echo 0;
    }
}
 private function set_config_option(){
    $config =array(
        'allowed_type' => 'gif|jpg|png|jpeg|pdf|doc|xml|zip|rar',
        'file_size'  => '100',
        'max_width'  => '1024',
        'overwrite'  => TRUE,
        'max_height' => '768',
    );
    return $config;
}

型号

 private function set_config_option(){
    $config =array(
        'allowed_type' => 'gif|jpg|png|jpeg|pdf|doc|xml|zip|rar',
        'file_size'  => '2048000',
        'max_width'  => '1024',
        'overwrite'  => TRUE,
        'max_height' => '768'
    );
    return $config;
}

public function Doupload(){         
    $target_path = 'uploads/';
    $target_file = $target_path. basename($_FILES['uploadimg']['name']);
    $base_url = base_url();
    $img_title = $this->input->post('imgname');

    $this->upload->initialize('upload', $this->set_config_option());
  //  $img = $this->upload->do_upload();    
   }

请帮助我...

模型未接收 $_FILES 对象。为什么你将上传过程分成两个文件(模型和 Controller ？，你在数据库中存储一些东西？)。在 codeiniter 文档中:https://ellislab.com/codeigniter/user-guide/libraries/file_uploading.html全部在同一个文件( Controller )中。

尝试遵循示例或尝试在 Controller 中添加:

$this->upload_model->Doupload($_FILES);

在模型中:

public function Doupload($file){
    $target_path = 'uploads/';
    $target_file = $target_path. basename($file['uploadimg']['name']);

我猜您使用以下方式加载库: $this->load->library('upload'); 或通过自动加载配置类。希望对您有帮助!
