If you switch it around you'll get a notice
If you switch it around you'll get a notice because the IF evaluates
from left to right. So you just want to make sure you check isset()
first.
This would throw a notice:
if($_POST['UserWishesDateRange'] == 'T'
isset($_POST['UserWishesDateRange'])) {
Aha! That must be what I tried
Why do you all always use isset?
Why do you don't use array_key_exists instead? is it a more semantic
solution?
?php
$key = 'UserWishesDateRange'; # just to make statement shorter
if( array_key_exists($key, $_POST ) 'T' == $_POST[$key] )
{
echo ' the key exists... and it is a T '';
}
this is not intelligence its just pure math. the '' says if BOTH
expressions are true then the whole expression is true.
so if the first one is false, the whole is false, why checking the next one
in the underlaying C it would be something like this
{
if ( expression == false ) return false;
if (

the single is a logical AND so a() NOR b() is evaluatet ! its usually used on
binary integer.
e.g. 0x0001 0x0001 = 0x0001 equlals TRUE while 0x0002 0x0001 equals FALSE
so something like $a $b guides to some very interisting results depending of
their values
but nothing u expect.
while
That should be !== not !===

Hi sunday coders,
I've been using this kind of logic on one PHP site I work on to
display one thing or another depending on whether the form was
submitted or not:
if($_POST['UserWishesDateRange']) { //--line 79
echo'submitted';
}

Try this instead:
if (isset('UserWishesDateRange'])) {
// [...stuff goes here...]
}

But on another site it still works, but gives this error:
Notice: Undefined index: UserWishesDateRange in
/home/vs/site/phvs/bl/7solarsecrets/admin/trackingcode.html on line 79
I assume that is because the error display settings are set to a more
rigorous level in this latter site.

Thank you guys for the isset() heads up. And Ben, for this good
explanation of error reporting!
As others have pointed out, it's a good idea to call isset() on a
POST-variable before trying to get at its value.
