Question

我正在尝试将照片上传到特定文件夹，并将其网址存储到数据库，但我遇到了未定义索引的问题！

这是用于上传图片的代码

$time = time();
    $_SESSION['storeid'] = 11;
    $target_dir = "uploads/store/products/";
    $target_file1 = $target_dir . basename($_FILES["productimages1"]["name"]) . $_SESSION['storeid'] . $time;
    $target_file2 = $target_dir . basename($_FILES["productimages2"]["name"]) . $_SESSION['storeid'] . $time;
    $target_file3 = $target_dir . basename($_FILES["productimages3"]["name"]) . $_SESSION['storeid'] . $time;
    $uploadOk = 1;

    $imageFileType1 = pathinfo($target_file1,PATHINFO_EXTENSION);
    $imageFileType2 = pathinfo($target_file2,PATHINFO_EXTENSION);
    $imageFileType3 = pathinfo($target_file3,PATHINFO_EXTENSION);

    move_uploaded_file($_FILES["productimages1"]["tmp_name"] . $_SESSION['storeid'] . $time, $target_file1);

    move_uploaded_file($_FILES["productimages1"]["tmp_name"] . $_SESSION['storeid'] . $time, $target_file2);
    move_uploaded_file($_FILES["productimages1"]["tmp_name"] . $_SESSION['storeid'] . $time, $target_file3);

    $image1=basename( $_FILES["productimages1"]["name"] . $_SESSION['storeid'] . $time,".jpg");
    $image2=basename( $_FILES["productimages2"]["name"] . $_SESSION['storeid'] . $time,".jpg");
    $image3=basename( $_FILES["productimages3"]["name"] . $_SESSION['storeid'] . $time,".jpg");

和html是

<form action="" method="post">
<input type="file" name="productimages1[]" id="product1" /> 
<input type="file" name="productimages2[]" id="product1" /> 
<input type="file" name="productimages3[]" id="product1" />
</form>

任何人都可以看看它有什么问题吗？

Answer 1

将enctype="multipart/form-data"添加到您的表单。

<form action="" method="post" enctype="multipart/form-data">
...
...
</form>

在php中，由于您要存储多个上传数组的文件，请使用循环。像：

$time = time();
$_SESSION['storeid'] = 11;
$target_dir = "uploads/store/products/";

if(!empty($_FILES["productimages1"])){
  foreach($_FILES["productimages1"] as $image1){
   if(!empty($image1['tmp_name'])){
      $target_file1 = $target_dir . basename($image1["name"]) . $_SESSION['storeid'] . $time;
      move_uploaded_file($image1["tmp_name"] . $_SESSION['storeid'] . $time, $target_file1);
   }
  }
}

检查一下，

  <?php
    if(isset($_POST['submit'])){

        $time = time();
        $_SESSION['storeid'] = 11;

        $target_dir = "uploads/store/products/";
        $target_file1 = $target_dir . $_SESSION['storeid'] . $time.$_FILES["productimages1"]["name"];
        $target_file2 = $target_dir . $_SESSION['storeid'] . $time.$_FILES["productimages2"]["name"];
        $target_file3 = $target_dir . $_SESSION['storeid'] . $time.$_FILES["productimages3"]["name"];

        move_uploaded_file($_FILES["productimages1"]["tmp_name"], $target_file1);
        move_uploaded_file($_FILES["productimages2"]["tmp_name"], $target_file2);
        move_uploaded_file($_FILES["productimages3"]["tmp_name"], $target_file3);

     }
    ?>


<form action="" method="post" enctype="multipart/form-data">
    <input type="file" name="productimages1" id="product1" /> 
    <input type="file" name="productimages2" id="product1" /> 
    <input type="file" name="productimages3" id="product1" />
    <input type="submit" value="submit" name="submit"/>
</form>

在表单中添加了enctype="multipart/form-data"。将文件上载到服务器时需要这样做。
