Question

我正在尝试通过以下代码上传图片。虽然我的if条件正在执行，如下所示，但图像没有移动到我给出的指定路径。我的代码如下。这是我的HTML代码

<form enctype="multipart/form-data" action="catcher.php" method="POST">
Send this file: <input name="userfile" type="file" />
    <input type="submit" value="Send File" />
</form>

这是我的PHP代码

<?php
$uploaddir = '/xampp/project/';
echo '<pre>';
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploaddir)) {
    echo "File is valid, and was successfully uploaded.\n";
} else {
    echo "Possible file upload attack!\n";
}

echo 'Here is some more debugging info:';
print_r($_FILES);

print "</pre>";

?>

任何机构都可以指出我的代码有什么问题我的意思是为什么我试图上传的图片没有移动到指定的路径，

Answer 1

move_uploaded_file()要求第二个参数是目标文件，而不是目录。

你可以这样做：

$filename = $uploaddir . basename($_FILES['userfile']['tmp_name']);

if( move_uploaded_file($_FILES['userfile']['tmp_name'], $filename)){
// ...

但很有可能多个用户会尝试上传同名文件，所以我严格建议处理这种可能性。

Answer 2

 $folder =  "../images/stories/";
$result =   move_uploaded_file($_FILES['excel']['tmp_name'], $folder.$filename);

提供目标文件夹名称。（在上面的代码中，$ folder是目标路径变量）您可以看到此功能的详细信息：

function upload($name,$tmp_name){   

$fileextarr=explode('.',$name);
$fileextarr[0];
$fileext=$fileextarr[count($fileextarr)-1];
$fpath = "../images/stories/lab_excel/";
$filename = ereg_replace(" ","_",$fileextarr[0]).'.'.$fileext;


//You can use restriction on file extensions also. (not necessary)

if($fileext=="xls" || $fileext=="xlsx" || $fileext=="doc"|| $fileext=="docx" || $fileext=="jpeg" || $fileext=="png" || $fileext=="gif" || $fileext=="tiff" || $fileext=="bmp" || $fileext=="jpg")
{
    $uploadedfile = $filename;

}

//Here is the use of destination path:



 $folder =  "../images/stories/lab_excel/";
$result =   move_uploaded_file($_FILES['excel']['tmp_name'], $folder.$filename);

/*echo $folder.$_FILES['excel']['name'];
die();*/

if($result){
$msg="File Uploaded Successfully";
    return $folder.$filename;
}
else
{
    return false;
}

}
