I have a simple file form with a file
<form enctype="multipart/form-data" action="upload.php" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="30000" />
Send this file: <input name="userfile" type="file" />
<input type="submit" value="Send File" />
</form>
The upload.php script which is :
$uploaddir = 'uploads/'; // the dir where i upload the images //
$uploadfile = $uploaddir . $_FILES['userfile']['name'];
if (isset($_POST['Submit']))
$userfile = $_POST['userfile'];
print "<pre>";
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
print "File is valid, and was successfully uploaded. ";
} else {
print "File upload error!\n";
}
is incomplete as you can see, and here are my questions:
a) how to verify if the uploaded file is an image ?
b) how to print the image?
c) how to resize the image?
Thanks.
