php - 如何在CodeIgniter框架中将图像上传到文件夹并插入到数据库

Question

需要将图像上传到文件夹并将文件名插入MySQL，图像名称应该是唯一的。 我的 Controller 代码是:

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{  
    $config['upload_path'] = 'uploads/gallery/'; 
    $config['allowed_types'] = 'gif|jpg|png|bmp|jpeg';
    $this->load->library('upload', $config);
    $upload = $this->upload->do_upload('image_file');
    $title=$this->input->post('title');
    $value=array(
        'title' => $title,
        'image_name' => $new_image_name,
        'crop_name' => $crop_image_name
    );
}

Answer 1

这样做

public function uploadImageFile() //gallery insert
 { 
    if($_SERVER['REQUEST_METHOD'] == 'POST') {
    $new_image_name = time() . str_replace(str_split(' ()\\/,:*?"<>|'), '', 
    $_FILES['image_file']['name']);
    $config['upload_path'] = 'uploads/gallery/'; 
    $config['allowed_types'] = 'gif|jpg|png|bmp|jpeg';
    $config['file_name'] = $new_image_name;
    $config['max_size']  = '0';
    $config['max_width']  = '0';
    $config['max_height']  = '0';
    $config['$min_width'] = '0';
    $config['min_height'] = '0';
    $this->load->library('upload', $config);
    $upload = $this->upload->do_upload('image_file');
    $title=$this->input->post('title');
    $value=array('title'=>$title,'image_name'=>
    $new_image_name,'crop_name'=>$crop_image_name);}
