I would like to check that a file uploaded to my OpenShift app has a text extension (.txt or .tab). Following some advice given here I wrote the following code, with echoes added to help debug:
$AllowedExts = array('txt','tab');
echo "AllowedExts: " . $AllowedExts[0] . " and " . $AllowedExts[1] . "<br>";
$ThisPath = $_FILES['uploadedfile']['tmp_name'];
echo "ThisPath: " . $ThisPath . "<br>";
$ThisExt = pathinfo($ThisPath, PATHINFO_EXTENSION);
echo "ThisExt: " . $ThisExt . "<br>";
if(!in_array($ThisExt,$AllowedExts) ) {
$error = 'Uploaded file must end in .txt or .tab';
}
echo "error echo: " . $error . "<br>";
On uploading any file, the echoed response was:
AllowedExts: txt and tab
ThisPath: /var/lib/openshift/************/php/tmp/ phpSmk2Ew
ThisExt:
error echo: Uploaded file must end in .txt or .tab
Does this mean that OpenShift is renaming the file upon upload? How do I get the original filename and then check its suffix? More generally, is there a better way to check the file type?
$_FILES['uploadedfile']['tmp_name']
contains the name of a temporary file on the server (which can be moved with move_uploaded_file()
). If you want to check the original name of the uploaded file on the client machine use $_FILES['uploadedfile']['name']
.
That's not an Open Shift issue, it's the standard way of PHP.
