Hi there,

I am writing a script that will do form validation. The problem that I am running into I think is with the smarty templates I am using on the form page.

Here is the script so far


function checkvalid(){
   username=joinform.signup[username:1:6:16:::username_check].value;
   password=joinform.signup[password:1:6:16:::password_check].value;
   zip=joinform.signup[password:1:6:16:::password_check].value;
   email=joinform.signup[email:1:1:128:::email_check].value;
   letters="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";

   if (username.length == 0 || password.length ==0 || email.length == 0 || zip.length == 0)
   {
      alert("Please Fill Out All Fields");
      return false;      
   }
   if (username == password)
   {
      alert("Username and Password must be different");
      return false;      
   }
   if (letters.indexOf(username.substr(0,1)) == -1)
   {
      alert("Username must start with a letter");
      return false;      
   }
   if (joinform.email.value.indexOf("@")==-1 || joinform.email.value.indexOf(".") ==-1)
   {
      alert("Not a valid e-mail!");
       return false;   
   }
   
   
}//end check valid



Notice how the name value for the form inputs looks like:
signup[username:1:6:16:::username_check] thats how it actually looks on the php file



<form action="signup.php" method="POST" onsubmit="return checkvalid() " id="joinform">

<input type="hidden" name="site" value="{$smarty.request.site}">
<input type="hidden" name="program" value="{$smarty.request.program}">
<input type="hidden" name="campaign" value="{$smarty.request.campaign}">
<input type="hidden" name="nats" value="{$nats_code}">
<input type="hidden" name="step" value="2">
<input type="hidden" name="username" value="{$vars.username}">
<input type="hidden" name="signup[rename_old_member]" value="1">

   <TD class="join_name">Username:</TD>
   <TD class="join_value">
      <input class="join_input" type="text" name="signup[username:1:6:16:::username_check]" value="{$vars.username}">

   <TD class="join_name">Country:</TD>
   <TD class="join_value">
      <select class="join_select" name="signup[country]">{html_options options=$countries selected=$country}</select>
   </TD>
</TR>
<TR>
   <TD class="join_name">Membership:</TD>
   <TD class="join_value">
      <select name="signup[optionid]" class="join_select">
         {html_options options=$join_options selected=$vars.optionid}
      </select>
      <span class="join_error">
      {if $errors.optionid}<br>{$errors.optionid}
      </span>{/if}



The script keeps returning an error and I am confused as to what is wrong and how to solve it. Any help is much appreciated. Thanks!
