need help with form

[ultrasound0000]

I'm submitting a form to an external site.  The page where I post on the external site processes the form values.  I don't have access to the external site, so I have no control of it.

 

I need to validate the form data using PHP before I post to this external site.  I have figured out how to validate the form in PHP, so that's not a problem.

 

My problem is: how do I then post the form to the external site once the validation is all clear?  If I put the external site in the action="externalsite.com" then my PHP server-script validation is skipped. 

 

I don't have a DB back-end or cUrl installed, so for now can't use either and I'm looking for another solution.

 

I am stuck so any help would be greatly appreciated.

yes you can. have that submit page submit to a different page (maybbe sanitize.php)

 

have that page take the variables, and populate a form with however many hidden fields that you need, and then submit the form with javascript IE

$var = $_POST['my+var'];
//sanitize here

?>
<form action="what_ever.ext" method="post" name="MyForm">
       <input type="hidden" name="hiddenfield1" value="<? echo $var; ?>">
     </form>
     
     <script language="javascript" type="text/javascript">
    document.MyForm.submit();
     </script>
     <noscript><input type="submit" value="verify submit"></noscript>

 

Hope that helps!
