I'd like to put in the source of the content page my own form for example:
<form action="my_script.php" method="post" name="name" id="name">
<input type="company_name" name="textfield">
</form>

This form will run my_script.php. The script should process variables sended by post (in this example company_name variable), then give some results (from my own databases) and put it back one the webpage.

How to do it, cause now I have SS parsing error (cant parse form tag):
</form>
------------^

thanks for support. I've read it.

But the problem is, how to run my own script which will access my own database (from my other application) and give back results on silverstripe page.

could You help me with short instruction.

I'm also curious about this.. I need to submit a form to an external site for processing. I cannot get the code from the remote location as it's a third party processor.

So in short I would love the ability to customise the action tag of the <form> tag. I realise that this may be accomplished with javascript on the user end, but this does not work for two reasons:

1) The odd chance that the user does not have js enabled.
2) That I already have a script rewriting the action tag (also third party js!)

Thanks for any help!
