Question

W3C validation for xhtml transitional - head parameters

Asked by: ncw

Experienced strange behaviour with the w3c validator, it would not accept php parameters being used within files outputing data in within the <head></head> tags. For example, using code that has been validated fine on other servers, using the code below caused the validator to think that the <head> tag was not closed. Both the constants and parameter were correctly define and the site was working. I feel sure it must be something to do with the server environment.

Anyone else had such experiences? The server is a LAMP.

require(DIR_WS_LANGUAGES . $language . '/' . 'header_tags.php');
 
echo '  <meta http-equiv="Content-Type" content="text/html; charset=' . CHARSET  . '" />'."\n";

I've found that the validator at jigsaw.w3.org validates the site as xhtml transitional with no errors (only css warnings), whereas the validator at validator.w3.org is showing 31 errors and in the code where it's highlighting  the error it's also showing some sql code which it shouldn't be seeing!

The validator at validome.org also returned similar spurious errors.

 

by: KravimirPosted on 2009-05-27 at 16:13:08ID: 24488516

The validator at jigsaw.w3.org is the CSS validator, not an XHTML validator.  Please post a URL to an example page.

If I copy and paste the page source from the browser view source into a new file then that validates ok. So something in the php code is effecting the validation.

I've temporarily removed th footer which was causing errors. Then if I remove a menu with <ul> and <li> tags the page validates. In analysing the menu I find that a sql query is causing 22 spurious validation errors eg:

end tag for "br" omitted, but OMITTAG NO was specified
& 1 ORDER BY i.v_order' at line 1<br><br>SELECT i.information_id, i.page_url,

The query works fine on the database, and how can a Php/Mysql query effect the validator?

This is *STRANGE*! I'm testing the php page in the W3C validator for xhtml transitional. In my code I have a Php variable in a query eg:
"select * from sometable where id = " . $id . " order by somefield";
and the W3c validator fails.

Ok so I change the sql code to:
"select * from sometable where id = '" . $id . "' order by somefield";
and the W3c validator passes.

I've added single quotes around the parameter to get a pass, but the value is an integer, and in any case why should it be effecting xhtml validation - it's server side code!

Finally in another file a similar error was being triggered by a php variable in an sql string; the above solution didn't work, I had to replace the variable with a fixed value.
