Declared var in php page cannot be seen in function ?

Probably an easy problem, but can't figure it out for some reasons !

I have a PHP page in hich i declared a var called $strAction. Now, this var can't be seen in a function of this page (well, it should be visible as a global scope for this page, no ?).

Anyway here's the code :

PHP Code:

---

$strAction = '';
function IsEnabled()
{
    if( $strAction == 'lookup' || $strAction == 'delete') // Line X
        return ' disabled ';
    else
        return '';
}

...

Notice: Undefined variable: strAction in page.php on line X

I've only had limited experience w/ PHP, but... the experience I do have has taught me that unless you explicitly create the variable as global, it's only going to be visible within it's section. In my case, I had a variable in some PHP code, then some straight HTML, followed by a second PHP code section where I tried to use the variable. IT choked in the second sectioon when I tried to use the variable. When I declared it as global, it began working fine.... go figure.... try it and see what happens. Can't hurt.

That error is actually only an annoying notice. You can either modify the php.ini file or disable it through the code. In the php.ini file look for the line:

error_reporting = E_ALL & ~E_NOTICE

an uncomment it. Comment all the others.

From within the code:

PHP Code:

---

error_reporting(E_ALL & ~E_USER_NOTICE); 


---

Try this:

Code:

---

$strAction = '';
function IsEnabled() {
    global $strAction;

    if( $strAction == 'lookup' || $strAction == 'delete') // Line X
        return ' disabled ';
    else
        return '';
}

Thanks for the help !
Seems to work ok now
