如何将php模板分配给生成的url？

I have a form in a php file:

<form method="post" id="form" action="<?php bloginfo('url'); ?>/results/">
    <input type="text" name="height" placeholder="Enter height">
    <input type="text" name="weight" placeholder="Enter weight">
    <input type="submit" id="export">
</form>

That generates a random url when clicked (like mydomain.com/gLd3a) using jQuery:

$("#export").click(function(){
    url = $("#form").attr("action");
    url = url.replace("/results/","/<?php echo $randomString ?>/");
    $("#form").attr("action", url).submit();
});

But I'm trying to automatically make the generated url show content from a php template (results.php).

I tried to do that using the action="<?php bloginfo('url'); ?>/results/" but /results/ is being replaced by the random string, therefore has no effect.

Is there any other way to assign that php to the generated url please?
