我编写了以下代码,用于验证用户上传的图像。但是,当代码运行时,它返回一个空白页面。这是我的代码:

HTML <form>标题):

<form class="registerbodysections" enctype="multipart/form-data" method="post" action="php/registrationForm.php">

PHP

<?php

$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$email = $_POST['email'];
$confirmemail = $_POST['confirmemail'];
$birthday = $_POST['birthday'];
$birthmonth = $POST['birthmonth'];
$birthyear = $_POST['birthyear'];
$location = $_POST['location'];
$picture = $_FILES['picture'];
$picturelocation = "../img/uploads/'$email'/picture/'$picture[\'type\']";

echo var_dump($picture); //for testing purposes, but does not get executed

function imageFormatCheck ($fileMime) {
    $datatypes = array(
    'image/jpg',
    'image/gif',
    'image/png',
    'image/jpeg'
    );

    foreach($datatypes as $datatype) {
        if ($fileMime !== $datatype) {
            return false;   
        }
    }
    return true;
}

function checkFileType() {
    if(imageFormatCheck($fileMime)) {
        header('Location: http://google.com');
        exit();
    } else {
        header('Location: http://facebook.com');   
        exit();
    }
}

function moveFile() {
    if(!move_uploaded_file($tmpName, $picturelocation)) {
        header('Location: http://google.com');
        exit();
    } else {
        header('Location: http://facebook.com');
        exit();
    }   
}


if(count($picture)) {

    $tmpName = $picture['tmp_name']; //when I var_dump $picture I receive a single array, not a double array as often seen
    $fInfo = $finfo_open(FILEINFO_MIME_TYPE);
    $fileMime = finfo_file($fInfo, $tmpName);
    $finfo_close($fInfo);

    checkFileType();
    moveFile();

}

$userDataArray = array(
    $firstname,
    $lastname,
    $birthday,
    $birthmonth,
    $birthyear,
    $location,
    $picturelocation
);

?>

我添加了标题用于测试目的。但是,这些都不会被执行。相反,如上所述,每次都显示空白页面。 HTML <form>元素是正确的,这就是为什么我没有在这里包含它们。问题可能是什么想法?提前谢谢!

注意:目录$picturelocation实际上并不存在。 move_uploaded_file()是否可以动态创建它,如果它不存在?在文档中找不到任何相关内容。

文件信息可从Super global $ _FILES获得。您可以从以下列表中获取名称,类型,大小和文件的信息。

$_FILES['userfile']['name']
$_FILES['userfile']['type']
$_FILES['userfile']['size']
$_FILES['userfile']['tmp_name']
