Question

我想通过商店图像路径创建一个图像上传到数据库的php表单，并将图像存储到服务器或目录中。我有点不确定如何进行图片上传。

数据库：CREATE TABLE IF NOT EXISTS `tbl_users` ( `id` int(11) NOT NULL AUTO_INCREMENT, `fullName` varchar(255) NOT NULL, `email` varchar(255) NOT NULL, 'pic' blob NOT NULL PRIMARY KEY (`id`),

<?php
session_start();
require_once 'class.user.php';
$user_home = new USER();

if(!$user_home->is_logged_in())
{
  $user_home->redirect('index.php');
}


if(isset($_POST['btn-register']))
{
  $fullName = $_POST['fullName'];
  $email = $_POST['email'];


  $stmt = $user_home->runQuery("SELECT * FROM bike WHERE id=:id");
  $stmt->execute(array(":id"=>$_SESSION['userSession']));
  $row = $stmt->fetch(PDO::FETCH_ASSOC);;

  if($reg_user->register($email,$fullName))
  {



    $message = "
            Thank You for registering  with us!<br/>
            <br />
            Thanks,<br/>
            <br />
            Site Admin";

    $subject = "Confirm Registration";
  }
  else
  {
    echo "sorry , query could no execute.";
  }
}

?>

        <tr>

             <tr>
             <td>SPicture:</td>
            <td><input type="file"  name="pic" required />
             </tr>

             </table>
  <button class="btn btn-large btn-primary" type="submit" name="btn-register">Register</button>

   </form>

PHP：

import java.io.IOException;

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;



     public class JsonToJava {

            public static void main(String[] args) throws IOException {
                try{
                    String json = "<YOUR_JSON>";
                    Gson gson = new GsonBuilder().create();
                    VendorInfo vInfo = gson.fromJson(json, VendorInfo.class);       
                    System.out.println(vInfo.getVendorName());              
                } catch(Exception ex) {
                    ex.printStackTrace();
                }
            }
        }

Answer 1

这一行之后：

$email = trim($_POST['email']);

为图片上传添加以下代码：

...

if(isset($_FILES['pic'])){
      $errors= array();
      $file_name = $_FILES['pic']['name'];
      $file_size = $_FILES['pic']['size'];
      $file_tmp = $_FILES['pic']['tmp_name'];
      $file_type = $_FILES['pic']['type'];
      $file_ext=strtolower(end(explode('.',$_FILES['pic']['name'])));

      $expensions= array("jpeg","jpg","png");

      if(in_array($file_ext,$expensions)=== false){
         $errors[]="extension not allowed, please choose a JPEG or PNG file.";
      }

      if($file_size > 2097152) {
         $errors[]='File size must be excately 2 MB';
      }

      if(empty($errors)==true) {
         move_uploaded_file($file_tmp,"images/".$file_name);
         echo "Success";
      }else{
         print_r($errors);
      }
   }

...

然后你必须在你的数据库中插入$ file_name。

Answer 2

您可以将文件上传到您的文件夹，如下所示：

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);    
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has     been uploaded.";
/*add here the insert on your tabl*/
    } else {
        echo "Sorry, there was an error uploading your file.";
  }

  <?php
