Testing if two fields have data in them

Im trying to test if two fields have been entered at the same time
I have tried many combinations but cant get it. My last effort was


if(isset($_POST['Link'] && isset($_POST['uploadedfile'])){
die('You can\'t select to upload a link and a file at the same time.');
}
else
{
STUFF HERE;
}

but still cant get it to work

Help appreciated

Ian

So what happens when you try? It gives you the error when it shouldn't,
or it doesn't give you the error when it should?

A blank field is not the same as NO field. I'm going to guess
that you mean:

if ((isset($_POST['Link']) && $_POST['Link'] != '')
&& (isset($_POST['uploadedfile']) && $_POST['uploadedfile'] != '') {

Watch the scope of the isset. I think you wanted:
if( isset($_POST['Link']) && isset($_POST['uploadedfile']) ) {

Thanks Gordon
Unfortunately your solution does not work. It allows the 'else' part of the
code to proceed

Thanks Dave
But I tried that and that isnt it either
It also allows the 'else' part of the code to proceed

contained the following:

isset will return true for certain form elements even if they are empty.

Assuming the elements are not checkboxes radio boxes or buttons, try

if(!empty($_POST['Link']) && !empty($_POST['uploadedfile'])){
....


If this doesn't work, let us know what elements you are dealing with.

But if the condition is false, the else clause SHOULD run. What's the problem?

Hi
The problem is that the alternative runs even when it shouldnt. The code
should be such that if the the two fields have something in them then an
error should be produced.

Let me expand on what Im trying to do
I wish the users to either to upload a file to my website or as an
alternative send a link to their website which is added to a table in my
database.
The first option the user browses for their file and it is submitted via
type=file
The second option uses type=text

What I wish to do is to stop user from putting data into both fields
I want the code to test the submitted data and if text field and file field
have something in them then a message would say 'You cant submit a link and
a file at the same time'

To see what Im trying to acheive go to

stick a print_r($_POST);die(); in where you have STUFF and send us the
output.
