表单上传文件无法显示

Question

表单上传文件无法显示，这是我的表单上传代码

<?php

$imageinfo = getimagesize($_FILES['img']['tmp_name']);

if($imageinfo['mime'] != 'image/gif' && $imageinfo['mime'] != 'image/jpeg') {

echo "<center><br>Sorry, we only accept GIF and JPEG images</br><br>param name: img<br>u can upload 

with CSRF";

exit;

}

$uploaddir = 'ex/';

$uploadfile = $uploaddir . basename($_FILES['img']['name']);

if (move_uploaded_file($_FILES['img']['tmp_name'], $uploadfile)) {

echo "File is valid, and was successfully uploaded.\n";

} else {

echo "File uploading failed.\n";

}?>

<form action="" method="post" enctype="multipart/form-data">

<input type="file" size="20" name="img" />

<input type="submit" name="upload" value="Upload" />

</form>

结果是

Sorry, we only accept GIF and JPEG images

param name: img

u can upload with CSRF

我想显示表单上传文件

这将起作用，您应该指定正确的路径<?php&nbsp; &nbsp;if($_SERVER["REQUEST_METHOD"] == "POST"){&nbsp; &nbsp; &nbsp; $imageinfo = getimagesize($_FILES['img']['tmp_name']);&nbsp; &nbsp; &nbsp; if($imageinfo['mime'] != 'image/gif' && $imageinfo['mime'] != 'image/jpeg') {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;echo "<center><br>Sorry, we only accept GIF and JPEG images</b><br>param name: img<br>u can upload&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;with CSRF";&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;exit;&nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; else{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;$uploaddir = '../path-to-move/';&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;$uploadfile = $uploaddir . basename($_FILES['img']['name']);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;if (move_uploaded_file($_FILES['img']['tmp_name'], $uploadfile)) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; echo "File is valid, and was successfully uploaded.\n";&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;} else {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; echo "File uploading failed.\n";&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}&nbsp; &nbsp; &nbsp; }}?><form action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']);?>" method="post" enctype="multipart/form-data"><input type="file" size="20" name="img" /><input type="submit" name="upload" value="Upload" />
