I had just found that missing & right before you posted. It never fails. I can look for hours and as soon as I ask for help - I see the problem. But, it still wasnt working so it def helps to spell things correctly HAA Thanks Larry. Much appreciated - as usual Wade

Ive been using what Ive learned this book for a long time now but Im stumped on something. I have a situation where I can not use a drop down list so I was going to use a links instead. link: href="index.php?p=performances?performance=Life_After_50" Im stumped as how to handle this code. In the index.php page I see the code: //Validate what page to show if(isset($_GET['p'])){ $p = $_GET['p']; } else if( isset($_POST['p'])) { //form $p = $_POST['p']; } else { $p = NULL; } But how does the page get redirected back to the performances.inc.php to access the performance variable data Life After 50?

FOUND IT!!! header("Content-Type=text/xml"); should be header("Content-Type:text/xml"); Changed that - its all fine. OMGOSH that is crazy that one little thing like a = instead of a : can do that. Ok.. thanks for the help - moving on with the book

Ok.. I noticed it only did that with the php tag at the top and thought maybe the page logic inserted the dashes itself but the above test says it didnt. Anyway, I dont know why that showed up but its not in my actual code.

Im testing something ..... <?php phpinfo(); ?>

Im just looked at that.... the <!-- isnt in my code. Its only in the code I posted here. This is what I have <?php #add_employee_xml.php header("Content-Type=text/xml"); echo '<?xml version="1.0" encoding="utf-8" standalone="yes" ?> <response> ';

Hartley, Im working with the code right out of the book that this forum is named after: //add_employee.js window.onload = init; function init(){ var ajax = getXMLHttpRequestObject(); if(ajax){ if(document.getElementById('results')){ document.getElementById('emp_form').onsubmit = function(){ ajax.open('post', 'add_employee_xml.php'); ajax.onreadystatechange = function() { handleResponse(ajax); } var fields = ['first_name', 'last_name', 'email', 'department_id', 'phone_ext']; for(var i = 0; i < fields.length; i++){ fields[i] = fields[i] + '=' + encodeURIComponent(document.getElementById(fields[i]).value); } var values = fields.join('&'); //alert(values); ajax.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); ajax.send(values); return false; } } } } function handleResponse(ajax){ if(ajax.readyState == 4){ if((ajax.status == 200) || (ajax.status == 304)) { var results = document.getElementById('results'); document.getElementById('first_name_label').className = 'title'; document.getElementById('last_name_label').className = 'title'; document.getElementById('email_label').className = 'title'; document.getElementById('department_id_label').className = 'title'; document.getElementById('phone_ext_label').className = 'title'; var data = ajax.responseXML; alert(data); var message = data.getElementsByTagName('result'); var errors = data.getElementsByTagName('error'); var temp = false; for(var i=0; i < errors.length; i++){ temp = errors[i].firstChild.nodeValue; document.getElementById(temp + '_label').className = 'error'; } results.innerHTML = message[0].firstChild.nodeValue; results.style.display = 'block'; } else { document.getElementById('emp_form').submit(); } } } and then the page its calling: <!--?php #add_employee_xml.php header("Content-Type=text/xml"); echo '<?xml version="1.0" encoding="utf-8" standalone="yes" ?--> <response> '; require_once('mysql.inc.php'); $error = false; if(!empty($_POST['first_name'])){ $fn = mysql_real_escape_string($_POST['first_name'], $dbc); } else { $error = true; echo '<error>first_name</error> '; } if(!empty($_POST['last_name'])){ $ln = mysql_real_escape_string($_POST['last_name'], $dbc); } else { $error = true; echo '<error>last_name</error> '; } if(!empty($POST['email'])){ $e = mysql_real_escape_string($_POST['email'], $dbc); } else { $error = true; echo '<error>email</error> '; } if(isset($_POST['department_id']) && is_numeric($_POST['department_id']) && ($_POST['department_id'] > 0)){ $did = (int) $_POST['department_id']; } else { $error = true; echo '<error>department_id</error> '; } if(isset($_POST['phone_ext']) && is_numeric($_POST['phone_ext']) && ($_POST['phone_ext'] > 0)) { $ext = (int) $_POST['phone_ext']; } else { $error = true; echo '<error>phone_ext</error> '; } // no errors if(!$error){ $query = "INSERT INTO employees (department_id, first_name, last_name, email, phone_ext) VALUES (NULL, $did, '$fn', '$ln', '$e', $ext)"; $result = mysql_query($query, $dbc); if(mysql_affected_rows($dbc) == 1){ echo '<result>The employee has been added.</result> '; } else { echo '<result>The employee could not be added due to a system error.</result> '; } } else { echo '<result>Please correct problems with the highlighted field(s) below.</result> '; } mysql_close($dbc); echo '</response> '; ?> I went back through and put the '; on a new line just like in the book thinking maybe it had to be that way to not mess up the xml.

Ok. Thanks for you response Larry. After looking through the book and over the code, I dont understand how to do that yet. Ill just put this book away until I understand js better.

Do you mean with this: if(ajax.readyState == 4){ if((ajax.status == 200) || (ajax.status == 304)) { which is inside the function handleResponse(ajax).

var errors = data.getElementsByTagName('error'); When I run the page my Firefox error console says: data is null add_employee.js line 44 -> which is the above line. I checked my code against that downloaded from the site and found no errors so I ran the code from the site and had the same issue. Ive been going over the code to see if I understand what is happening but I just dont understand js enough and what could be causing the errors. wade
