Ma voi come fate a validare il ? all'interno dei link?
Ad esempio...
<a href=Kit_ricarica.php?sessione=" . session_id() . " class=testobold>
...non piace a w3c e mi segna errore il ?
"You have used a character that is not considered a "name character" in an attribute value. Which characters are considered "name characters" varies between the different document types, but a good rule of thumb is that unless the value contains only lower or upper case letters in the range a-z you must put quotation marks around the value. In fact, unless you have extreme file size requirements it is a very very good idea to always put quote marks around your attribute values. It is never wrong to do so, and very often it is absolutely necessary. "
Dove stò sbagliando?
