Question

  if (isset($_POST['submit'])) {
        $name=$_FILES['file']['name'];
        $temp=$_FILES['file']['tmp_name'];
        move_uploaded_file($temp,$_SERVER['DOCUMENT_ROOT'] ."upload/files/".$name);
        $url="http://localhost/upload/files/".$name;



        $sql = "INSERT INTO photo (NAME,link)
       VALUES ('$name','$url')";

在这段代码中，sql工作，文件名在数据库中成功更新，但我无法在目录中移动文件。

这是错误：

警告：   move_uploaded_file（/应用/ XAMPP / xamppfiles / htdocsupload /文件/屏幕   拍摄2018-05-07在11.17.21 AM（2）.png）：未能打开输入代码   herestream：没有这样的文件或目录   第45行/Applications/XAMPP/xamppfiles/htdocs/upload/upload2.php

“警告：move_uploaded_file（）：无法移动......”

请帮忙！

Answer 1

您的网址更改错误或尝试此操作：

    <?php
    $target_dir = "uploads/files/";

    $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

    $uploadOk = 1;

    $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

    // Check if image file is a actual image or fake image

    if(isset($_POST["submit"])) {
        $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
?>

您可以使用以下代码上传文件

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
?>
