forms and href problem

[maslett]

Hi, i have a website that passes data between scripts using both links (ie href=script.pl?data=yay&etc=etc) and forms (using the post method). The problem is I want to pass some private data using a link - I could use a form (method=post) - but I really *want* to use a link. I have tried

<form method='post'>
<input type='hidden' secret_data='$data'>
<a href='/cgi-bin/display.pl'>Link</a>
</form>

but when I click the link no data is passed. When I display the $ENV variable REQUEST_METHOD it shows GET as the method instead of POST (as I would have expected).

Anyone???????

Ta,
Matt

Links and forms are mutually exclusive. To do what you're looking for, you'll want to look into a JavaScript solution to build the URL with the extra data, and/or submit the form itself.

While my JavaScript is very rusty and there is a better way to do this, something like this perhaps:

<script type="text/javascript" language="Javascript">
<!--
function submitme()
{
var myactionurl = "[URL unfurl="true"]http://www.domain.com/cgi-bin/display.pl?secret_data="[/URL] + element[0] + "&otherdata=" + element[1];

document.forms[0].action = myactionurl;
document.forms[0].method = "post";
document.forms[0].submit();
return true;

}

// -->
</SCRIPT>

<a href="javascript:void(0)" onClick="submitme();">Link name</a>

Cheers Rieekan, I'll have a go over the weekend and post my results!

<a href='/cgi-bin/display.pl?secret_data=$data;'>Link</a>

<form method='post' action='/cgi-bin/display.pl'>
<input type='hidden' name='secret_data' value='$data'>
</form>

In either case the variable $data is not populated
with anything just yet.
To populate the variable $data, you can:
1) Type in the secret data when you build the page.
2) Use javascript as mentioned above.
3) You can use perl to populate the variable if you
are building the page dynamically using perl, php or
some other language.
