    copied!<p>I have created a script which checks if an email is valid. I have another function which checks if a username is taken. When checking both textboxes I get 'error on page' if these are checked on there own it works fine.</p> <p>Below is my code</p> <pre><code>&lt;script type="text/javascript"&gt; function AjaxFunction() { var httpxml; try { // Firefox, Opera 8.0+, Safari httpxml=new XMLHttpRequest(); } catch (e) { // Internet Explorer try { httpxml=new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { httpxml=new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) { alert("Your browser does not support AJAX!"); return false; } } } function stateck() { if(httpxml.readyState==4) { document.getElementById("msg").innerHTML=httpxml.responseText; } } httpxml.open("GET",ajax.php,true); httpxml.send(null); } &lt;/script&gt; &lt;form name=form action=''&gt; Username &lt;input type=text name=username onBlur="AjaxFunction();"&gt;&lt;br&gt;&lt;div id="msg"&gt;&lt;/br&gt;&lt;/div&gt;&lt;br&gt; Email Address&lt;input type=text name=email onBlur="AjaxFunction();"&gt;&lt;div id="msg"&gt;&lt;/div&gt; &lt;br&gt; &lt;input type=submit value=Submit &gt; &lt;/form&gt; </code></pre> <p>This is my ajax.php file....note the function for checking is not on this page, I have simply used echo $username as an example of this not working.</p> <pre><code>&lt;? $username=$_GET['username']; echo $username; $email = $_GET['email']; if (!eregi("^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,3})$", $email)){ echo "&lt;font color=red&gt; Invalid email&lt;/font&gt;"; }else{ echo "&lt;font color=green&gt; Valid Email&lt;/font&gt;";} ?&gt; </code></pre> <p>Thanks =)</p>
