Weird Validation errors

Hello guys. I currently re-designed a page utilizing a control page.

 

I am using an XHTML strict declaration at the top of my document header file (see below).

 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

 

But when I try to validate I get around 256 errors. And for some reason weird "PHP sessions strings are added to my url's" I have no idea what this is. Below is an example of some of these errors.

 

Can someone help me?

 

#  Warning  Line 61, Column 74: cannot generate system identifier for general entity "PHPSESSID"

…hp?page=Intranet&section=Overview&[b][color=red]PHPSESSID=17b9d814888eb176e68af35bc8f817[/color][/b]…

✉

An entity reference was found in the document, but there is no reference by that name defined. Often this is caused by misspelling the reference name, unencoded ampersands, or by leaving off the trailing semicolon (. The most common cause of this error is unencoded ampersands in URLs as described by the WDG in "Ampersands in URLs".

Entity references start with an ampersand (&) and end with a semicolon (. If you want to use a literal ampersand in your document you must encode it as "&" (even inside URLs!). Be careful to end entity references with a semicolon or your entity reference may get interpreted in connection with the following text. Also keep in mind that named entity references are case-sensitive; &Aelig; and æ are different characters.

If this error appears in some markup generated by PHP's session handling code, this article has explanations and solutions to your problem.

Note that in most documents, errors related to entity references will trigger up to 5 separate messages from the Validator. Usually these will all disappear when the original problem is fixed.
# Error Line 61, Column 74: general entity "PHPSESSID" not defined and no default entity

…hp?page=Intranet&section=Overview&[b]PHPSESSID=17b9d814888eb176e68af35bc8f817[/b]…

This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details.

Thanks for replying Karl.

 

O.K.

 

Below you should find my menu which I include in my header which I then include in my control page.

 

The control page includes a functions page.

 

<div class="megaMenuHover">
<a href="./" class="megaMenuHover">Home</a>

<a href="home.php?page=AboutUs&section=AboutBTI" id="megaanchor" class="megaMenuHover" <?php testPage("AboutUs"); ?>>About BTI</a>

<!--Mega Menu Anchor-->
<a href="home.php?page=Research" id="megaanchor2" class="megaMenuHover" <?php testPage("Research"); ?>>Research</a>


<a href="home.php?page=Education&section=EducationOverview" id="megaanchor3" class="megaMenuHover" <?php testPage("Education"); ?>>Education and Outreach</a>

Hello kenrbnsn,

 

Thanks for answering. Yes I do. I use it in my json_proxy file that handles the querying for my search.

Below is the code. I had commented out the "session_start();" but that did not do anything.

 

<?php

/*
We wanna have sessions enabled for json/ajax because we might in the future add authentication
and session tracking so that only authorized users can get JSON data.
*/
session_start();

/*
The usual connect stuff.  This should come from a single include that other scripts share, but
for now we'll just put it here.
*/
$conn = mysql_pconnect("myhost", "username", "password") or trigger_error(mysql_error(),E_USER_ERROR); 
mysql_select_db ("someDatabse") or die ("I cannot select the database '$dbname' because: " . mysql_error());

/*
Lookup function for staff.  It uses a single lookup parameter which comes from a text box
in the browser.  This means that it could contain one or two words (first name and last name) in
any order.  We'll ignore any characters (a ',' for example) which are not letters.
*/

function getStaffInfo($term){
	if(null == $term) return null;

	//trim $term to remove leading and ending spaces, and return null if $term is empty
	$term = trim($term);
	if("" === $term) return null;

	//replace any non-alphabetic characters with spaces
	$term = ereg_replace("[^A-Za-z]", " ", $term);

	/*
	At this point $term should have one or more values (first/last):
		$term = "Brutnell"   
		$term = "Rosero Camilo" or "Camilo Rosero"
	It could happen that there are multiple spaces in the case of two values (first/last names), 
	so lets ereg_replace for that case
	*/
	$term = ereg_replace(" +", " ", $term);

	//convert all characters to UPPER CASE to make comparison with database values easier
	$term = strtoupper($term);

	//if $term has two values, then the following will return an array of length greater than 1
	$term_array = explode(" ", $term);

	//our $sql statement will basically compare the values in the array with the first and last
	//names in staff_contact_table (in upper case), in any order, to make sure we catch all our 
	//cases
	$where_clause = "WHERE ";
	if(1 == count($term_array)){
