RE: [Phplib-users] How to validate a oohform with js ?

[Taylor, S. <Ste...@uk...>]

$f = new form;

$f->add_element(....
...

            
$f->start("MyFunction","POST","index.php","","FormName");
             ^^^^ This parameter specifies that you
                  want to create a form onsubmit javascript function.
...

$f->finsh("",
          "
             if (f.input1.value=='' && f.input2.value=='')
             {
                alert('your message');
                return false;
             }
          "
          );

Use the finish function to put none phplib generated code into the onsubmit
function.
i.e. function finish($after, $before)

Therefore, the above call will add onsubmit attribute to the form tag

<FORM ......."onsubmit"="return MyFunction_Validator(this)">
...


And generate the javascript function code.
<SCRIPT>
function MyFunction_Validator(f)
{
   // $before
   if (f.input1.value=='' && f.input2.value=='')
   {
      alert('your message');
      return false;
   }

   phplib generated javascript code
   
          
   // $after
   
   ...
}
</SCRIPT>
...

Subject: [Phplib-users] How to validate a oohform with js ?


How can i validate if either one or the other of two textfields (or both)
is being fillied with some sort of text ?

normally i would use js with a script like this:

<SCRIPT>
function validate()
{
	if (document.form.input1.value=="" &&
document.form.input2.value=="")
	{
	   alert ("please insert some text in one of the input fields");
	}
	else
	{
	  document.form.submit();
	}
}
</SCRIPT>

and use this function on a link

<a href="javascript:Validate();">submit</a>

but how can i do that with phplib, with oohforms and templates ?

i couly only validate both fields if they are empty, but what if only one
must be entered with text ?


best regards Benjamin
