【问题描述】：

我正在创建一个脚本，其中只能上传某些视频类型，但目前卡住了。

这是我的代码 -

<?php

$title = isset($_POST['title']) ? $_POST['title'] : null;
$desc = nl2br(isset($_POST['description'])) ? $_POST['description'] : null;
$name = isset($_POST['fullname']) ? $_POST['fullname'] : null;
$email = isset($_POST['email']) ? $_POST['email'] : null;
$country = isset($_POST['country']) ? $_POST['country'] : null;

$video = isset($_FILES['video']);
$videoname = isset($_FILES['video']['name']);
$videotmp = isset($_FILES['video']['tmp_name']);
$videosize = isset($_FILES['video']['size']);
$videotype = isset($_FILES['video']['type']);
$videoacceptable = array(
        "video/mp4",
        "video/ogg",
        "video/quicktime",
);

$videopath = "/videos/";
$videofile = $videopath . $video;

if(isset($_POST['submit'])) {

//ERROR MESSAGES / VALIDATION

if(empty($title)) {
    $errors[] = "A title is required"; 
    echo "<style type=\"text/css\"> #title { background-color:#F5A9A9;border:1px solid #DF0101; } </style>";
} elseif(strlen($title) > 80) {
    $errors[] = "Your title can only be 80 characters long"; 
    echo "<style type=\"text/css\"> #title { background-color:#F5A9A9;border:1px solid #DF0101; } </style>";
}
if(empty($desc)) {
    $errors[] = "A description is required";
    echo "<style type=\"text/css\"> #description { background-color:#F5A9A9;border:1px solid #DF0101; } </style>";
}
if(empty($name)) {
    $errors[] = "Please enter your full name";
    echo "<style type=\"text/css\"> #fullname { background-color:#F5A9A9;border:1px solid #DF0101; } </style>";
} elseif(strlen($name) > 32) {
    $errors[] = "Your name can only be 32 characters long";
    echo "<style type=\"text/css\"> #fullname { background-color:#F5A9A9;border:1px solid #DF0101; } </style>";
}
if(empty($email)) {
    $errors[] = "Please enter your email address";
    echo "<style type=\"text/css\"> #email { background-color:#F5A9A9;border:1px solid #DF0101; } </style>";
} elseif(strlen($email) > 50) {
    $errors[] = "Your email addess can only be 50 characters long";
    echo "<style type=\"text/css\"> #email { background-color:#F5A9A9;border:1px solid #DF0101; } </style>";
} elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
    $errors[] = "Please enter a valid email address";
    echo "<style type=\"text/css\"> #email { background-color:#F5A9A9;border:1px solid #DF0101; } </style>";
}
if($videosize = 0) {
    $errors[] = "You forgot to upload a video";
} elseif($videosize >= 20000000) {
    $errors[] = "Your video size is too large, 20mb max";
} elseif(!in_array($videotype, $videoacceptable)) {
    $errors[] = "The file type is not allowed, only allowed .mp4, .ogg and .mov";
}

if(count($errors) === 0) {
    $connect = mysqli_connect("localhost","username","password");
        if(!$connect) {
            header("Location:"); // ADD ERROR LINK
        }
    $dbselect = mysqli_select_db("database");
        if(!$dbselect) {
            header("Location:"); // ADD ERROR LINK
        }

    $query = mysqli_query("INSERT INTO cover_videos(title, desc, name, email, country, videotmp, videotype, videosize, videopath) VALUES('$title','$desc','$name','$email','$country','$videotmp','$videotype','$videosize','$videopath')");
    move_uploaded_file($videotmp, $videofile);

    //SEND AN EMAIL TO THE USER     
    $to = $email;
    $subject = "Thank's for your upload";

    $message = '
        <html>
            <head><title>We have received your video</title></head>
            <body>
                <h3>Good News!</h3>
                <p>We have recieved your video and is awaiting approval.</p>
            </body>
        </html>
    ';

    $headers = 'FROM: no-replyk' . "\r\n";
    $headers = 'MIME-Version: 1.0' . "\r\n";
    $headers = 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
    $headers = 'X-Mailer: PHP/' . phpversion();

    mail($to, $subject, $message, $headers);

    header("Location:"); //SUCCESSFUL UPLOAD PAGE

    }

}

?>

所以发生的事情是，当我上传文件时，我正在上传 .mov 文件，但弹出的错误消息是“文件类型不允许，仅允许 .mp4、.ogg 和 .mov”，但是.mov mime 在 videoacceptable 数组中，所以我现在有点卡住了，知道是什么问题吗？

【解决方案1】：

$videoacceptable = array(
    "video/mp4",
    "video/ogg",
    "video/quicktime"
);

请检查这可能有助于解决您的错误。

或者代替“quicktime”试试“mov”。

【讨论】：

刚刚尝试了您的建议，但仍然弹出该错误消息，但感谢您的建议
请在执行代码前尝试打印 $videotype。这将帮助您了解视频类型的确切值。

【解决方案2】：

<?php
if(isset($_POST['submit']))
{
$video = $_FILES['video']; 
$videoname = $_FILES['video']['name'];
$videotmp = $_FILES['video']['tmp_name'];
$videosize = $_FILES['video']['size'];
echo $videotype = $_FILES['video']['type'];
$videoacceptable = array(
    "video/mp4",
    "video/ogg",
    "video/quicktime"
);
$videopath = "/videos/";
$videofile = $videopath . $video;   
}
?>
<form method='POST' action="" enctype='multipart/form-data'>
<input type='file' name='video'>
<input type='submit' name='submit'>
</form>

请试试这个。希望它会有所帮助。
