Code: Select all
$testrx = $_POST['file'];
switch ($testrx) {
case "" :
if ($row_userinfo['Logo']=="nologo.gif"){
$logox = "nologo.gif";
}
else
$logox = $_COOKIE['USERNAME'].".jpg";
break;
}
I have a input filed type="file" but script always writes the
Code: Select all
$logox = $_COOKIE['USERNAME'].".jpg";
Did i do something wrong?

Where does the array var $row_userinfo['Logo'] get set? What is it's value and how does it relate to $_POST['file']?

$row_userinfo['Logo'] get's it's value from the database ( table users, field - logo)
$_POST['file'] get's it's value from the form1 textbox (<input name="file" type="file" class="text3" value="" size="32"> )
i want to do the following; in case the "file" field has not changed script will leave the old user logo and in case the filed
has changed it will write the USERNAME + extension from a cookie
Code: Select all
$logox = $_COOKIE['USERNAME'].".jpg";

I would have done it like this.
Code: Select all
$testrx = isset($_POST['file']) ? trim($_POST['file']) : "";
switch ($testrx) {
case "" :
// ....
break;
or even
Code: Select all
$testrx = isset($_POST['file']) ? trim($_POST['file']) : "";
switch (true) {
case (empty($testrx)) :
// ....
break;
