Question

这是我的HTML代码 “ post.html”

<!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="upload" id="upload">
<input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html>

这是我的PHP代码“ upload.php”

<?php
target_dir = "upload/";
$target_file = $target_dir . basename($_FILES["upload"]["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["upload"]["tmp_name"]);
if($check !== false) {
    echo "File is an image - " . $check["mime"] . ".";
    $uploadOk = 1;
} else {
    echo "File is not an image.";
    $uploadOk = 0;
}
}
?>

我得到的结果是

File is an image - image/jpeg.

文件执行没有问题，但问题是，即使我成功执行了代码，只要我通过html代码上传任何文件或图像，文件都不会出现在上传文件夹中。

P.S我在wampserver上使用php7

您应在代码行$uploadOk = 1;之前使用以下代码行

move_uploaded_file($_FILES["upload"]["tmp_name"], $target_file);

赞：

if (move_uploaded_file($_FILES["upload"]["tmp_name"], $target_file)) {
    echo "The file ". basename( $_FILES["upload"]["name"]). " has been uploaded.";
} else {
    echo "Sorry, there was an error uploading your file.";
}

在其他网站上处理代码时，请先了解那里写的内容，然后继续。 :-)

$check = getimagesize($_FILES["upload"]["tmp_name"]);这行代码用于获取图像大小并进行大小验证。

Try this :   


 <?php

    // Check if image file is a actual image or fake image
    if(isset($_POST["submit"])) {

    target_dir = "upload/";
    $target_file = $target_dir . basename($_FILES["upload"]["name"]);
    $uploadOk = 1;
    $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

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

图片文件上传无法在Wamp服务器上运行
