$value = isset($_POST['title']) ? $_POST['title'] : '';    
    echo 'title:'.$value;
    $target_path = "uploads/"; //Declaring Path for uploaded images
    for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array

        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable



           if( move_uploaded_file($_FILES["file"]["tmp_name"][$i], $target_path . $_FILES["file"]["name"][$i])){

错误/警告：

( ! ) Notice: Undefined index: title in C:\wamp\www\multiple_image_upload\upload.php on line 5

Answer 1

这个的两个原因

1）您忘记了表单中title的输入类型

<input type="text" name="title" />

2）可能不是$_POST['title']而是

 $_POST['tender']

你的upload.php中的

提交时，输入类型文本未在php文件中接收
