Errors found while checking this document as XHTML 1.0 Transitional!Result: 34 Errors

document type does not allow element X here
✉

The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed).

One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error).

ID X already defined

An "id" is a unique identifier. Each time this attribute is used in a document it must have a different value. If you are using this attribute as a hook for style sheets it may be more appropriate to use classes (which group elements) than id (which are used to identify exactly one element).

value of attribute Y invalid: X cannot start a name

It is possible that you violated the naming convention for this attribute. For example, id and name attributes must begin with a letter, not a digit.

Joomla! 1.5.14 Stable mod_slidemenu 1.5.0

I haven'ted tested this for validation, that might come in the future, or possibly of somebody did it and sent me the code, I'd appreciate sharing the code with the rest of the world

My website generates about 300+ errors in W3C Validation. Has there been any progress in fixing this? All the errors are pretty much the same problem, something starting with a number instead of a letter. I'd really appreciate if this can be fixed or if anyone has suggestions. Thank you.

Is this being completely ignored?

----- Polski ------
Rozwiazalem ten problem po przez usuniecie samego wpisu id="".
Skrypt dziala poprawnie na róznych przegladarkach.

wystarczy zmienic; plik helper.php

Stara wersja:
linia 145 -> // Start the item
linia 146 -> $this->_buffer .= '<li access="'.$this->_current->access.'" level="'.$depth.'" id="'.$this->_current->id.'">';

Nowa wersja:
linia 145 -> // Start the item
linia 146 -> $this->_buffer .= '<li access="'.$this->_current->access.'" level="'.$depth.'" id="'.$this->_current->id.'">';



----- English ------
I Solved this problem by removing the same entry id = ""
The script works correctly on different browsers

change file helper.php

Old:
linia 145 -> // Start the item
linia 146 -> $this->_buffer .= '<li access="'.$this->_current->access.'" level="'.$depth.'" id="'.$this->_current->id.'">';

New:
linia 145 -> // Start the item
linia 146 -> $this->_buffer .= '<li access="'.$this->_current->access.'" level="'.$depth.'" id="'.$this->_current->id.'">';

this is the same...


I replace with on line 256 (maybe we have different versions?)

I added "itemid" before id because html element id can´t start with number

You need to edit tmpl/default.php on line 167-189:


and than css... (another story)



but there are still W3C errors because of same submenus id
