Error on global

Hello,
trying to implement some function that hooks zem_contact, I’m following the guidelines on this page but I get an error regarding the global declaration global zem_contact_form;

This is the error I get (4.5.4): Parse error: syntax error, unexpected ‘zem_contact_form’ (T_STRING), expecting variable (T_VARIABLE) or ‘$’

I’m putting the global prefix outside any function, but within the plugin.

Any suggestion?

Thanks!

Re: Error on global

must use a variable:

global $zem_contact_form;

Re: Error on global

Grazie Marco!

I’m having still some troubles following the API guides,

global $zem_contact_form;
$evaluator = &get_zemcontact_evaluator(); 

This returns Fatal error: Call to undefined function get_zemcontact_evaluator()

Any idea?
Thanks a lot

Re: Error on global

Ci vuole lo spazio:

$evaluator =& get_zemcontact_evaluator();

L’ho scoperto anche io ora: =& è un operatore di assegnazione in php!!

$a = 42;
$b =& $a;
//later
echo $a; // 42
echo $b; // 42
$a = 13;
echo $a; // 13
echo $b; // 13

Must use $evaluator =& get_zemcontact_evaluator();

=& is an assigment operator by reference

Re: Error on global

Ciao,
thanks, it returns unknown function as well, even in the correct form as you suggest

(che bello parlare la propria lingua) ;)
