I have this code and some problems… It checks if last name is empty that works but i can’t take the value from it. I mean registration works but i submit no value to last name (when i add that check to see if last name is at least 3 characters i can’t submit at all)
This is my java code for submit
[code]function signup(){
var fn = _(“firstname”).value;
var ln = _(“lastname”).value;
var u = _(“username”).value;
var e = _(“email”).value;
var p1 = _(“pass1”).value;
var p2 = _(“pass2”).value;
var c = _(“country”).value;
var g = _(“gender”).value;
var status = _("status");
if(u == "" || e == "" || p1 == "" || p2 == "" || c == "" || g == "" || fn == "" || ln == ""){
status.innerHTML = "<strong style=\"font-size:13px; color:#F00;\">Please complete all fields before submitting</strong>";
} else if(p1 != p2){
status.innerHTML = "<strong style=\"font-size:13px; color:#F00;\">Your passwords do not match!</strong>";
} else {
status.innerHTML = '';
var ajax = ajaxObj("POST", "index.php");
ajax.onreadystatechange = function() {
if(ajaxReturn(ajax) == true) {
if(ajax.responseText != "signup_success"){
status.innerHTML = ajax.responseText;
_("signupbtn").style.display = "block";
} else {
window.scrollTo(0,0);
_("indlayout").innerHTML = "Succes etc........";
}
}
}
ajax.send("fn="+fn+"&ln="+ln+"&u="+u+"&e="+e+"&p="+p1+"&c="+c+"&g="+g);
}
}[/code]
And this is my PHP Code:
[php]<?php

I really can’t find what’s wrong with this. Thanks.
