在URL中保留一个GET变量

Question

I have a bit of an odd question, I'm sure most of you realise that these sorts of questions arise out of certain situations that a developer has no control over!

I would like to work out how to keep a querystring parameter in the URL at all times. If the parameter is not set, I'd like a default to be appended to the URL ?param=something

I asked a previous question relating to this and have been able to use htaccess to add a default query - but this only works fir the initial request whereas I need to ensure it is always present in the address.

I am thinking of using a cookie - set with PHP and then queried with .htaccess.

So, I am asking if this is possible and if there is a better way of doing this?

Answer 1

Without changing all the URLs I can't see this being possible and as discussed it is a very hacky way to do it.

I would suggest you give them a "special" button that they use for copying a link. Make them use this button to copy the link instead of the URL. You can then control the data properly without hacking the website.

Edit: You "could" add some JQuery in to append ALL links with your param. Have you thought about this?

$(document).ready(function() {
  $('a[href]').each(function() {
    this.href = this.href + '?something=<?php echo $_SESSION["myparam"]; ?>'
  });
});

You could get the param from the initial page load / session but this would require your users to have JS enabled (Which most people do now).

p.s Untested semi-pseudo code. I can test it properly if you decide to go down this route.
