Question

我正在尝试将视频上传到我的上载文件夹。我从这里的另一个问题得到了代码，效果很好。但我一直收到此通知错误，但我不知道如何解决。我整天都在努力。我试图检查它是否为isset()，但仍然无法正常工作。有人可以帮我吗？

<?php

$allowedExts = array("jpg", "jpeg", "gif", "png", "mp3", "mp4", "wma");
$_FILES = $_FILES['file'];
$extension = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);
$unique = date('Y-m-d_H-i-s');

if ((null !==($_FILES["file"]["type"] == "video/mp4")
    || (null !==($_FILES["file"]["type"] == "audio/mp3"))
    || ($_FILES["file"]["type"] == "audio/wma")
    || ($_FILES["file"]["type"] == "image/pjpeg")
    || ($_FILES["file"]["type"] == "image/gif")
    || ($_FILES["file"]["type"] == "image/jpeg"))

&& ($_FILES["file"]["size"] < 2000000)
&& in_array($extension, $allowedExts)) {

    if ($_FILES["file"]["error"] > 0) {

        echo "Return Code: " . $_FILES["file"]["error"] . "<br />";

    } else {

    echo 'File uploaded successfully';

    if (file_exists("upload/" . $_FILES["file"]["name"])) {

        echo $_FILES["file"]["name"] . " already exists. ";

    } else {

        $datetime = date('Y-m-d_H-i-s');

        move_uploaded_file($_FILES["file"]["tmp_name"],
        "uploads/" . $_FILES["file"]["name"] . $datetime . md5($_FILES["file"]["name"]));

    }
    }

} else {

    echo "Invalid file";
}
?>

<form action="profile.php" id="videoupload" method="post" enctype="multipart/form-data">

<label for="file"><span>Filename:</span></label>
<input type="file" name="file" id="file" /> 
<br />
<input type="submit" name="submit" value="Submit" />

</form>

Answer 1

$_FILES['file']

表示您的输入类型=名为“ file”的文件。如果没有名为“ file”的输入，则会收到未定义的索引通知。如果有的话

$_FILES = $_FILES['file'];

这将给其他代码带来错误。因为它尝试覆盖$ _FILES。

Answer 2

您正在尝试在上传文件之前处理文件上传。您必须检查表单是否首先发布。

<?php

if (isset($_FILES['file'])) {
    $allowedExts = array("jpg", "jpeg", "gif", "png", "mp3", "mp4", "wma");
    // $_FILES = $_FILES['file'];  // <-- remove this line
    $extension = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);
    $unique = date('Y-m-d_H-i-s');

    if ((null !==($_FILES["file"]["type"] == "video/mp4")
        || (null !==($_FILES["file"]["type"] == "audio/mp3"))
        || ($_FILES["file"]["type"] == "audio/wma")
        || ($_FILES["file"]["type"] == "image/pjpeg")
        || ($_FILES["file"]["type"] == "image/gif")
        || ($_FILES["file"]["type"] == "image/jpeg"))

    && ($_FILES["file"]["size"] < 2000000)
    && in_array($extension, $allowedExts)) {

        if ($_FILES["file"]["error"] > 0) {

            echo "Return Code: " . $_FILES["file"]["error"] . "<br />";

        } else {

            echo 'File uploaded successfully';

            if (file_exists("upload/" . $_FILES["file"]["name"])) {

                echo $_FILES["file"]["name"] . " already exists. ";

            } else {

                $datetime = date('Y-m-d_H-i-s');

                move_uploaded_file($_FILES["file"]["tmp_name"],
                "uploads/" . $_FILES["file"]["name"] . $datetime . md5($_FILES["file"]["name"]));

            }
        }

    } else {

        echo "Invalid file";
    }
}
?>

<form action="profile.php" id="videoupload" method="post" enctype="multipart/form-data">

<label for="file"><span>Filename:</span></label>
<input type="file" name="file" id="file" /> 
<br />
<input type="submit" name="submit" value="Submit" />

</form>

注意：未定义索引：文件上传视频
