form field validation

[ghostme]

Hello good pple of the forum,
I am validating my form fields using php, ok let’s say there is no text in the firstname text field, but there is text in the lastname field, when I hit the submit button, the validation text echos out that the firstname text field is empty and then displays the again (which is index.php). But the is my previous text in the lastname text field disappears. Pls how can I overcome this?
Thank you.

if((!$first)||(!$last)||(!$email)||(!$edu)||($_FILES['resume']['type']!='application/msword'))
         {
         echo 'you did not submit the following info<br/>';
         if(!$first)
         {
         echo 'first name is a required field<br/>';
         }
         if(!$last)
         {
         echo 'last name is a required field<br/>';
         }
         if(!$email)
         {
         echo 'email is a required field<br/>';
         }
         if(!$edu)
         {
         echo 'highest qualificaiton is a required field<br/>';
         }
         if($_FILES['resume']['type']!='application/msword')
         {
         echo ' make sure the file type is a Microsoft Word document<br/>';
         }
         include 'index.php';
         exit();
         }

Instead of reloading the page, output the code error and provide a back button and the data should be there.

use something like this

<?php
$fname="";
$lname="";
$error="";
if(isset($_POST['submit'])){
//Check if data field is empty
    $fname=$_POST['fname']; 
    $lname=$_POST['lname']; 
    if(!$fname || !$lname) $error="Empty Data fieldS ";
    else{
        // insert data into db
    }
}
if($error || !isset($_POST['submit'])){
echo $error;

?>
<table border="0"><form action="" method="post"> 
<tr align="left"><td>First Name</td>
<td><input name="fname" type="text" size="40" value="<?php echo $fname; ?>"></td></tr>
<tr align="left"><td>Last Name</td>
<td><input name="lname" type="text" size="40" value="<?php echo $lname; ?>"></td></tr>
<tr><td colspan="2" align="center">
<input name="create" type="submit" value="Enter">
<INPUT class=button accessKey=r tabIndex=1 type=reset value="Reset Fields"></td></tr>
</form></table>
<?php
