Possible to allow change theme from a link

Involved Joined: Feb 03, 2006 Posts: 269

This one had me stumped, I mean I have tried and failed miserably Embarassed

What I was trying to achieve was letting someone choose / select a theme via a link

Now I know there was/is a theme preview block, a submit form and I know you can do it from Your Account

But I wanted to allow a user or even a non user to simply click a link and it would load the site with a specific theme

I dont think its been done before, maybe it was done on phpthemes.net but that site is now gone so I cant recall how they did it exactly

Are you looking to permanently change the theme for a user or just set a cookie for users/non-users to temporarily change the theme?

Hey Palbin,

I guess set a cookie until they change it again... that would be the ideal situation

Are you doing this for an RN site or another nuke variant. I just need to know so I know what to give you.

Here is a quick example. It is important to note that when you set the cookie it will not be available until the next page load. So you will need to use $_GET['theme'] on the first page load if you need it. It will be very important to escape this value if you are using it in a DB call.

If you need a more specific help with a certain implementation let me know.

Code:




<?php





if (!empty($_GET['theme'])) {


   $theme = $_GET['theme'];


   /**


   * This is set to expire in 30 days.  Change the 30 to the numbr of days required.


   */


   $themeExpire = time()+60*60*24*30;


   setcookie('theme', $theme, $themeExpire, '/', 'www.YourDomain.com', false, false);


} else {


   $theme = '';


}





if (!empty($_COOKIE['theme'])) {


   echo 'The theme cookie is set to ' , $_COOKIE['theme'] , '.';


} else {


   echo 'The theme cookie is not set.';


}





echo '<br /><br />';





echo '<a href="?theme=theme1">Theme 1</a><br />';


echo '<a href="?theme=theme2">Theme 2</a><br />';


echo '<a href="?theme=theme3">Theme 3</a><br />';





?>

haha who rattled your cage !!! lmao

Its for visitors actually (so before there registered)... I want them to view the site in the preferred theme, so they click a link (game) and it takes them to the site viewing the games theme..

made me chuckle though Very Happy

Sweet thanks Palbin

I have to shoot out now for a few hours but I will try it out this evening

I would have never ever had been able to come up with something like that, I would love to learn some new stuff

I couldn't resist having a go... im using it on localhost would that matter ?

I cant seem to get it to work, doesn't want to set the cookie

I just threw the code into a test.php in the root and changed the themes and domain name to http://localhost/ravens_250

Im presuming its the domain name, I dont have a live install to play on at the moment but I can install one later today, right got to shoot out !!!

hehe

I will try local tonight, but I would try dropping the http:// and only making it "localhost/ravens_250".

You know that in RN 2.5 you can set 2 themes - one for anonymous and one for registered users? Just thought I'd mention it Smile

Posted: Thu Jan 26, 2012 11:45 am

Can't you just exclude those extra values when using setcookie?
setcookie('theme', $theme, $themeExpire);

This would probably be better for testing locally. I have read about problems with certain browsers and using localhost as a domain in a cookie.
