Question

我在promotions.php上有一张图片。当我点击“编辑”链接时，“标题”，“描述”和“图像”等变量将传递给doEditPromotion.php的页面表单。

我可以传递'标题'和'描述'以显示在doEditPromotion.php的页面表单上，但不能显示图像值。

任何人都可以帮我吗？谢谢！

doEditPromotion.php - ＆gt;

<?php
  session_start();
  include "dbfunction.php";

  $id = $_REQUEST['id'];


 $query = "SELECT title, description, image, promotionID FROM promotion WHERE promotionID = '$id'";

  $result = mysqli_query($link, $query);

  $row = mysqli_fetch_array($result);


        $title = $row['title'];
        $description = $row['description'];
        $image = $row['image'];


// check if the form has been submitted. If it has, process the form and save it to the database

    if (isset($_POST['save']))
    {
        $title_save = $_POST['title'];
        $description_save = $_POST['description'];
        $target = 'images/';
        $target = $target.basename($_FILES['photo']['name']);
        $pic = ($_FILES['photo']['name']);
        move_uploaded_file($_FILES['photo']['tmp_name'], $target);

// check that firstname/lastname fields are both filled in
 if ($title_save == '' || $description_save == '' || $pic == '')
 {
 // generate error message
 $error = 'ERROR: Please fill in all required fields!';
 echo $error;
 }

    else
 {  
  // save the data to the database
  $query = "UPDATE promotion SET title = '$title_save', description = '$description_save', image = '$pic' WHERE promotionID = '$id'"; 
  $result = mysqli_query($link, $query);

  // once saved, redirect back to the view page
 header("Location: promotions.php"); 
 }   
 }
          ?>

Answer 1

您将上传的文件命名为upfile，然后尝试将其作为照片进行访问。执行print_r($_FILES)然后更改以下内容之一：

$_FILES['photo']['name'] // Either change photo to upfile
...
<input type='file' name='upfile' id='image' src='...' /> // Or upfile to photo

如何将图像值从一种形式传递到另一种形式？
