爲什麼多次上傳沒有被插入到數據庫中

Question

這裏我試圖插入多個圖像到數據庫中，但它們沒有被插入。圖像正確上傳到文件夾，但不知道爲什麼它沒有進入數據庫。 這裏是我的圖片上傳功能

public function multiple_upload_files($path) 
{ 
    $images = array(); 
    if(!empty($_FILES['files']['name'])){ 
     $filesCount = count($_FILES['files']['name']); 
     for($i = 0; $i < $filesCount; $i++){ 
      $_FILES['file']['name'] = $_FILES['files']['name'][$i]; 
      $_FILES['file']['type'] = $_FILES['files']['type'][$i]; 
      $_FILES['file']['tmp_name'] = $_FILES['files']['tmp_name'][$i]; 
      $_FILES['file']['error'] = $_FILES['files']['error'][$i]; 
      $_FILES['file']['size'] = $_FILES['files']['size'][$i]; 
      $config['upload_path']= './uploads/'.$path.'/'; 
      $config['allowed_types'] = 'gif|jpg|png|jpeg'; 
      $config['max_size']= '2000'; 
      $config['max_width'] = '4000'; 
      $config['max_height'] = '6500'; 
      $config['file_name']='upld-file'.time(); 
      $this->load->library('upload', $config); 
      $this->upload->initialize($config); 
     if ($this->upload->do_upload("file")) { 

      $images[] = $this->upload->data(); 
     } 
     else { 
     redirect('admin/view-product'); 

     } 
    } 
      return $images; 
} 

這裏是我的插入代碼

$path='products'; 
    if($this->multiple_upload_files($path)) 
    { 
     $img=implode(',',$images); 
     $data = array('product_name' => $this->input->post('product_name'),'image'=>$img); 
     $status = $this->Admin_model->db_insert($table='products',$data); 
     if($status) 
     { 
      $this->session->set_flashdata('message','Product added Successfully'); 
     } 
     else 
     { 
      $this->session->set_flashdata('message','Insertion failed'); 
     } 

的問題是圖像上傳到上傳文件夾，而不是數據庫。

您正在從方法返回圖像數組，但沒有收到它。改變你的代碼如下

$path='products'; 
$images= $this->multiple_upload_files($path); 
if($images) 
{ 
    $img=implode(',',$images); 
    $data = array('product_name' => $this->input->post('product_name'),'image'=>$img); 
    $status = $this->Admin_model->db_insert($table='products',$data); 
    if($status) 
    { 
     $this->session->set_flashdata('message','Product added Successfully'); 
    } 
    else 
    { 
     $this->session->set_flashdata('message','Insertion failed'); 
    }
