How to create and run a function in a php form?

[fleong888]

//Class definition
class Form_IDRetriever extends Page
{
public $vLinkBtn = null;
public $vSendBtn = null;
public $vEMail = null;
public $vPasswordPanel = null;
public $Label1 = null;
public $Label2 = null;
function Form_IDRetrieverJSLoad($sender, $params)
{
?>
//Add your javascript code here
{document.getElementById('vEMail').focus();}
<?php
}

function Form_IDRetrieverJSSubmit($sender, $params)
{
?>
//Add your javascript code here

function validate_email(field,alerttxt)
{
with (field)
{
apos=value.indexOf("@");
dotpos=value.lastIndexOf(".");
if (apos<1||dotpos-apos<2)
{alert(alerttxt);return false;}
else {return true;}
}
}
//-------------------------------------
{
if (findObj('vEMail').value=='')
{alert("Please enter a Email Address");
document.getElementById('vEMail').focus();
return(false);}
else
if (validate_email($this->vEMail,"Not a valid e-mail address!")==false)
{$this->vEmail.focus(); return(false);}
}
<?php

}

}

Is this the correct way to create a function call validate_email?
Thank you

Depends

In this context it works ok. If you want to call it from some other place in your code it won't be visible due to scope.

BTW validate_email($this->vEMail is not js.

FWIW Here is an email validation that uses regular expressions.

var sendto=prompt ('Enter your email address');
if ((sendto != null) && (sendto != ""))
  {
  emailRe = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*\.(\w{2}|(com|net|org|edu|int|mil|gov|arpa|biz|aero|name|coop|info|pro|museum))$/;
  if (!emailRe.test(sendto.toLowerCase()))
      {
      alert(sendto + ' is an invalid email.');
      return(false);
      }
