Question

我设法上传并调整了多张图片的大小，一切都很好然后，如果没有选择上传图像，我想显示错误我把一个if语句加载错误，但这造成了严重破坏。

每次我选择图像并上传时，最后一个都会重复，而不会调整大小再说一次，如果我删除if else，那就完全没问题了。

谢谢您的帮助和时间。

function do_upload(){


    $path = array();
    $count = count($_FILES['userfile']['size']);

    foreach($_FILES as $key=>$value){
        for($n=0; $n<=$count-1; $n++) {
            $_FILES['userfile']['name']=$value['name'][$n];
            $_FILES['userfile']['type']    = $value['type'][$n];
            $_FILES['userfile']['tmp_name'] = $value['tmp_name'][$n];
            $_FILES['userfile']['error']       = $value['error'][$n];
            $_FILES['userfile']['size']    = $value['size'][$n];   

                $config['upload_path'] = './images';
                $config['allowed_types'] = 'gif|jpg|png|jpeg';

            $this->load->library('upload', $config);
            $this->upload->do_upload();
            $data = $this->upload->data();
            $path[] = $data['full_path'];
        }   



        if(!$this->upload->do_upload()){
            $error = array('error' => $this->upload->display_errors());
            $this->load->view('view_dashboard_error_car', $error);
        }
        else{
            $this->load->library('image_lib');   

            foreach($path as $p=>$ath){
                $config1 = array(
                'source_image'      => $ath,
                'new_image'         => './images',
                'maintain_ration'   => true,
                'overwrite'         => true, 
                'width'             => 600,
                'height'            => 400
                );

                $this->image_lib->initialize($config1);
                $this->image_lib->resize();
                $this->image_lib->clear();
            }       



            $this->load->view('view_dashboard_success_car');

        }





    }   




}

您正在运行$this->upload->do_upload()两次，因为您的foreach()会运行，然后您的if/else语句会运行。

您需要将if/else放入foreach循环中。您应该注意不要只是复制/粘贴它，但要确保每个图像只运行$this->upload->do_upload()一次。

CI文件上传，错误显示if / else导致图像重复
