Error "undefined function ..." means, you have not defined the function, yet. So make sure you have already put the "get_mypost" function in "Global Code" under "Server Events" -> "Global" -> "All Pages", afterwards regenerate at least the "userfn*.php" file.

Mobhar, Thank you for your reply.

1)
I am not sure where exactly i have to put this code " get_mypost("barcode") " and whether i need to change anything here.

2)
here, do i need to change anything?

function get_mypost($val) {
if ( isset($POST[$val]) && strlen(trim(@$POST[$val])) > 0 ) {
return(trim(@$_POST[$val]));
} else {
return('');
}
}

Double check you have placed your function definition in "Global Code" Server Event. Read Server Events and Client Scripts in the help file.
