[Php] Passing variables to different sites

Alex. · Jan 10, 2007

hi, i want to send a variable to a site i link to.

i cannot use a form, the script has to send the var without any user input.

ie, when i click an affilate link on my site, it redirects to a page on the site, which sends the var onto the next site.

using get is a last resort, because ideally i dont want the user to see the var.

I think you are going to have to pass the variable with get unless you want to make some JS script that creates a form, the action, the inputs, and submits it..

you could use CURL to pass the variable via POST data.

@link http://ca.php.net/curl

CURL wouldn't go to their URL though.. I think that's what he needs. If not, CURL would work good. http://www.namepros.com/code/257265-curl-class.html

here's code for two ways...

without using GET, you can do with a simple form and JS event to submit...

Code:

<form id="mysecretform" method="POST" action="http://link.to/passvar.to">
<input type="hidden" name="mysecretvar" value="itsasecret" />
</form>
<a href="#" onclick="document.getElementById('mysecretform').submit();">Method 1</a>

And like Dan said, you can make it all in a JS function to do it all so it's all reusable and such...
within <head> section...

Code:

<script type="text/javascript">
function sendSecret(myVar, myVal, target) {
    hiddenVal = document.createElement("input");
    hiddenVal.type = "hidden";
    hiddenVal.name = myVar;
    hiddenVal.value = myVal;
    myForm = document.createElement("form");
    myForm.method = "POST";
    myForm.action = target;
    myForm.appendChild(hiddenVal);
    document.body.appendChild(myForm);
    myForm.submit();
}
</script>

and on the link...

Code:

<a href="#" onclick="sendSecret('mysecretvar', 'itsasecret', 'http://link.to/passvar.to');">Method 2</a>

I tested them on FireFox, it should work on all browsers though

From what your saying... do you mean just using GET?

ie, when i click an affilate link on my site, it redirects to a page on the site, which sends the var onto the next site.

You could just use get and obfuscate the variables by encoding the values. Just set link to something like mypage.php?var1=lol&var2=whatever&etc=etc

Try plong0's code.

thanks for your help.
i think the simplest way for me to do it is encode the var and sand it via get.
