guys,

 

i need help on my form, i wanted to place an validation  message beside my text area

instead of displaying the error message on a separate page.

currently my error message is being displayed on a separate page and what happens

is when the error message appear, the user has to manually click back to the form

and retype the entire form.

 

how do i do this?

this is the current code in my form

and i wanted to have the validation message beside the name, email and contact of the personal information field

form method="post" action="referral.php?id=4">
      <table width="494" border="0" cellspacing="2" cellpadding="0">
        <tr>
          <td colspan="2"> </td>
        </tr>
        <tr>
          <td colspan="2" align="center" bgcolor="#e5e5e5" class="text7">Please make sure that correct information is supplied so we can get back to you. </td>
        </tr>
        <tr>
          <td colspan="2"> </td>
        </tr>
        <tr>
          <td colspan="2" bgcolor="#F7F7F7" class="text6">Your Personal Information </td>
        </tr>
        <tr>
          <td colspan="2" valign="top" class="text6"><img src="../images/main/spacer.gif" width="8" height="6" /></td>
        </tr>
        <tr>

                <input type="hidden" name="cc" value="pixeltrace@gmail.com" />
          </td>
        </tr>
        <tr>
          <td colspan="2"> </td>
        </tr>
      </table>
    </form>

 

and this is the current code of my referralsend.php

here i would like to happen here is the validation will just be done on the form page

and referralsend.php will just need to send all the information.

<?php

$yname = $_POST['yname'];
$yemail = $_POST['yemail'];
$ycontact = $_POST['ycontact'];
$inquiry = $_POST['inquiry'];
$cname = $_POST['cname'];
$cemail = $_POST['cemail'];
$ccontact = $_POST['ccontact'];
$cskills = $_POST['cskills'];
$recipient = $_POST['recipient'];
$cc = $_POST['cc'];


echo "<CENTER>";
if (($yname == "") || ($yemail == "") || ($ycontact == "")) {
echo '<br><br><span class="text7">Please complete the form. Thanks!</span><br>';
exit;
}

if(!email_is_valid($yemail)) {
echo '<br><br><span class="text7"><br>Email Address Invalid.<br>Please use a valid Email Address</span><br>';
exit;
}

$Message = "";
$Message .= "An Email from: $yname\n";
$Message .= "Contact Number: $ycontact\n";
$Message .= "Email Address: $yemail\n";
$ip = getenv("REMOTE_ADDR");
$Message .="IP address:".$ip."\n";
$Message .= "\n\n";
$Message .= "Type of scheme: $inquiry\n";
$Message .= "Candidate name: $cname\n";
$Message .= "Candidate contact number: $ccontact\n";
$Message .= "Candidate email: $cemail\n";
$Message .= "Candidate skills: $cskills\n";
$Message .= "\n\n";
$Message .= "Additional Questions/Inquiries: $additional\n";
$Message .= "\n\n";



$Header = $email;
$To = "$recipient, $cc";
$Subject = "JH Referral Scheme"; 

// mail($To,$Subject,$Message,"From: $Header","-f $EmailAdd"); last parameter might not be supported
mail($To,$Subject,$Message,"From: $Header");

echo '<script language=javascript> alert("Your message has been sent!");top.location = "referral.php?id=3";</script>';

function email_is_valid ($email) {
    if(eregi("^[0-9a-z_]([-_.]?[0-9a-z])*@[0-9a-z]([-.]?[0-9a-z])*\\.[a-z]{2,3}$", $email, $check)){
       if ( getmxrr(substr(strstr($check[0], '@'), 1), $validate_email_temp) ) {
         return TRUE;
       }
       // THIS WILL CATCH DNSs THAT ARE NOT MX.
       if(checkdnsrr(substr(strstr($check[0], '@'), 1),"ANY")){
         return TRUE;
       }
    }
    return FALSE;
  }
?>

 

hope you could help me with this.

Use this:

if ($yname=='' or $yemail=='' or $yemail==)  { 
         error ('Some required fields are blank.\\n'.
              'Please fill them in and try again.');
    }

 

Use the following code for error and then save it as validate.php and include it as

include("include/validate.php"); at the top of ur php code.

 

validate.php:

<?php 
function error($msg) {    
    ?>
      <script language="JavaScript">     
      <!--
       alert("<?php echo ($msg) ?> ");
        history.back();
   -->
    </script>        
    <?php
    exit;
}
?>

 

I think this will help.

Use only this, u echo the script, dont echo it.

Code:

if ($yname=='' or $yemail=='' or $yemail==)  { 
         error ('Some required fields are blank.\\n'.
              'Please fill them in and try again.');
    }

 

Other thing u did not include the validate.php.

Include it like this:

<?php
include("include/validate.php");
An ur rest of code.

Ok ur code will look this.

Code:

<?php
include("include/validate.php");
$yname = $_POST['yname'];
$email = $_POST['yemail'];
$ycontact = $_POST['ycontact'];
$inquiry = $_POST['inquiry'];
$cname = $_POST['cname'];
$cemail = $_POST['cemail'];
$ccontact = $_POST['ccontact'];
$cskills = $_POST['cskills'];
$recipient = $_POST['recipient'];
$cc = $_POST['cc'];

if ($yname=='' or $yemail=='' or $yemail=='')  { 
         error ('Some required fields are blank.\\n'.
              'Please fill them in and try again.');
    }


$Message = "";
$Message .= "An Email from: $yname\n";
$Message .= "Contact Number: $ycontact\n";
$Message .= "Email Address: $yemail\n";
$ip = getenv("REMOTE_ADDR");
$Message .="IP address:".$ip."\n";
$Message .= "\n\n";
$Message .= "Type of scheme: $inquiry\n";
$Message .= "Candidate name: $cname\n";
$Message .= "Candidate contact number: $ccontact\n";
$Message .= "Candidate email: $cemail\n";
$Message .= "Candidate skills: $cskills\n";
$Message .= "\n\n";
$Message .= "Additional Questions/Inquiries: $additional\n";
$Message .= "\n\n";

$Header = $yemail;
$To = "$recipient, $cc";
$Subject = "JH Referral Scheme"; 

// mail($To,$Subject,$Message,"From: $Header","-f $EmailAdd"); last parameter might not be supported
mail($To,$Subject,$Message,"From: $Header");

echo '<script language=javascript> alert("Your message has been sent!");top.location = "referral.php?id=3";</script>';

function email_is_valid ($email) {
    if(eregi("^[0-9a-z_]([-_.]?[0-9a-z])*@[0-9a-z]([-.]?[0-9a-z])*\\.[a-z]{2,3}$", $yemail, $check)){
       if ( getmxrr(substr(strstr($check[0], '@'), 1), $validate_email_temp) ) {
         return TRUE;
       }
       // THIS WILL CATCH DNSs THAT ARE NOT MX.
       if(checkdnsrr(substr(strstr($check[0], '@'), 1),"ANY")){
         return TRUE;
       }
    }
    return FALSE;
  }
?>

 

Now make a folder named 'include' in ur www directory, save the

following code there as validate.php

 

<?php 
function error($msg) {    
    ?>
      <script language="JavaScript">     
      <!--
       alert("<?php echo ($msg) ?> ");
        history.back();
   -->
    </script>        
    <?php
    exit;
}
?>

 

And then run ur page.

Also make sure that ur include/validate.php is accessed by this script.

I mean that give a validate directory here.

include("foldername/validate.php");

If u save ur validate.php in the same folder where ur this page is, then ok

But u forgot to use this () here:

include("validate.php");

 

correct it.
