[RESOLVED] IF not working

[keeptrying]

Can anybody tell me why this is not working - I think I've tried just about everything and am stuck.

I get an array from a form post (the data originally comes from MySQL database) and sort it out into separate variables

$supplier = $_POST[suppliers_info];
$supplierarray = explode(",",$supplier);
$supplierEmail = $supplierarray[0];
$supplierId = $supplierarray[1];
$supplierEmail2 = $supplierarray[2];

Now sometimes the variable $supplierEmail2 will have a value assigned to it, sometimes not. I currently have the data in the database set to 'none' but had it set to null initially.

if  ($supplierEmail2 == 'none')
{
echo "No email" . "<br />";
} else
{
echo $supplierEmail2 . "<br />";
}

no matter what I try this always echo's the $supplierEmail2 variable even though in the above example $supplierEmail2 is actually 'none'. When the field was NULL I tried:

if ( empty($supplierEmail2) )
{
    echo "No email";
} else
{
    echo $supplierEmail2 . "<br />";
}

I've also tried testing the strlen etc.
I must be doing something very wrong somewhere but cannot see where.

Print out $supplierEmail2 and see what you get.

from my example print_r($supplierEmail2) displays:
none
if there is an email address present then the email address is displayed.

this is the array from print_r($GLOBALS);

[supplierarray] => Array ( [0] => [e-mail] [1] => 1 [2] => none [3] => CompanyName[4] => ADD [5] => Global [6] => [7] => 0 ) [supplierEmail] => [e-mail] [supplierId] => 1 [supplierEmail2] => no)

not sure if that helps

none

That is impossible, unless $supplierEmail2 contains whitespace.

Try:

echo "'" . $supplierEmail2 . "'<br />";
if ($supplierEmail2 == 'none')
{
    echo "No email<br />";
}
else
{
    echo $supplierEmail2 . "<br />";
}

I expect that you either get:

'none'
No email

Or if the email is [e-mail]:

'[e-mail]'
[e-mail]

Laserlight you hit the nail on the head..

For some strange reason there was white space, all the values have a leading space in front of the value, I'm not sure where it is coming from but at least I can work it out now.

thank you very much for your help.
