Thanx for everyone. Now I'm little bit ok with ajax. These are my php form and ajax file. I want to check array values in php file using ajax function. I tried just one variable and it didn't work. Could you please tell me when I went wrong?
test.php
====== -
<?php
-
-
$array = array('Name'=>'FullName','Gender'=>'Gender','PhnNo' =>'PhoneNumber','Email' =>'EmailAddress','Address' =>'Address');
-
-
?>
-
-
<form action="test.php" method="post" id="test" >
-
.....
-
<tr><td height="24" >Full Name</td>
-
<td colspan="2"><input type="text" name="Name" size="40"/></td>
-
</tr>
-
<tr>
-
<td>Gender</td>
-
<td width="69"><input name="Gender" type="radio" value="1" /> Male</td>
-
-
<td width="297" ><input name="Gender" type="radio" value="2" />Female </td>
-
</tr>
-
-
<tr>
-
<td>Phone Number</td>
-
<td colspan="2"><input type="text" name="PhoneNumber" /></td>
-
</tr>
-
-
<tr>
-
<td>Email Address</td>
-
<td colspan="2"><input type="text" name="Email" /></td>
-
</tr>
-
<tr>
-
<td>Address</td>
-
<td colspan="2"><input type="text" name="Address" size="40" /></td>
-
</tr>
-
-
<tr>
-
-
<td colspan="2" align="right">
-
<input name="Submit" value="Submit" id="Submit" src="../images/Submit.jpg" type="image" alt="add" height="30" width="73" onclick="add();" />
-
</td>
-
</tr>
-
</form>
-
.....
-
test.js
====== -
function ajax() {
-
var request;
-
try {
-
request=new XMLHttpRequest();
-
}
-
catch (e) {
-
try {
-
request=new ActiveXObject("Msxml2.XMLHTTP");
-
}
-
catch (e) {
-
try {
-
request=new ActiveXObject("Microsoft.XMLHTTP");
-
}
-
catch (e) {
-
alert("Your browser does not support AJAX!");
-
return false;
-
}
-
}
-
}
-
return request;
-
}
-
-
-
function add(Name,Gender,PhnNo,Email,Address){
-
//alert ('test')
-
if (PhnNo){
-
PhnNo= document.getElementById(PhnNo).value
-
var regex = /^\d{11}$/;
-
if( !PhnNo.match(regex) )
-
return "Number is incorrect!!";
-
}
-
-
}

Your call to the add() function doesn't have any parameters, so the function won't do anything. There's no reference to the Ajax function. If you want to use PHP code to validate, then there's no point in using JavaScript validation as well. Make an Ajax request to your PHP validation script instead.
