Question

我在这里有这个代码输出一个图像..我需要改变它，因为目前它给了我类似的东西：test.jpg，我需要的是它给我test_s.jpg

我想使用重命名功能！

$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
$targetPath = str_replace('//','/',$targetPath);
$targetFile = $targetPath . $_FILES['Filedata']['name'];
tamano_nuevo_foto($stempFile, 420, $stargetFile);

Answer 1

你可以这样做：

$extension = array_pop( explode(".", $_FILES['Filedata']['name']) ); //get extension
$targetFile = $targetPath . "some_new_name".$extension;
tamano_nuevo_foto($tempFile, 420, $targetFile);

Answer 2

首先：您似乎有一条可由用户操纵的路径。您在路径中直接使用$ _REQUEST ['folder']是不好的。用户可以将ANYTHING放在那里，甚至像../../../之类的东西来移动你的文件系统！

要更改名称，只需：

$ targetFile = $ targetPath。 “myfilename.png”;

Answer 3

或者您可以使用此功能：

function add_s($file){
    $fName = substr($file, 0,strpos($file, "."));
    $fExtension = substr($file, strpos($file, "."));
    $newFName = $fName."_s".$fExtension;
    return $newFName;
}

Answer 4

您应该使用pathinfo和move_uploaded_file

$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/'; // should make this more secure, like a fixed path or in a whitelist
$targetPath = str_replace('//','/',$targetPath);
$ext = pathinfo($_FILES['Filedata']['name'], PATHINFO_EXTENSION);
$basename = pathinfo($_FILES['Filedata']['name'], PATHINFO_BASENAME);
$targetFile = $targetPath . $basename . "_s" . $ext;
move_uploaded_file ( $tempFile , string $targetFile)
//tamano_nuevo_foto($stempFile, 420, $stargetFile); // move and resize ??
