【问题描述】:
我有一个工作(图像)文件上传表单,但目前在上传后,它会打开一个“空白”页面,说明上传进度(例如“文件是图像 - 图像/jpeg。文件 01.jpg 已上传。”)。
上传后是否可以转到 URL 而不是这个简单的消息?让我们说 error.php 或 sent.php,这样它就不会让用户离开网站本身。
代码如下:
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($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.";
$uploadOk = 0;
}
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 10000000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
<form action="upload.php" method="post" enctype="multipart/form-data" id="ajax-contact-form">
Choose files:
<input type="file" name="fileToUpload" id="fileToUpload" />
<input type="submit" value="Send" name="submit">
</form>
【问题讨论】:
-
使用PHP的
header():php.net/manual/en/function.header.php -
我对php并不完全熟悉,所以我这里的方法可能非常错误,但我之前确实尝试用“header('Location:example.com/'); exit; "和类似的选项。然而,这只会带来一个完全空白的页面。
