i guess my php knowledge is not good enough to find a solution for the following problem:
I'm building a website where i have projects. Each project has tags like "webdesign, responsive, cms, print, flyer" etc. At the end of a project i want to recommend other projects, which have similar tags. I want to limit the recommendations to three other projects sorted by the hightest amount of same tags.
This is how far i got:
<?php $interessantes = $pages->find("tags=$page->tags, id!=$page->id"); ?>
to find other projects with the same tags, excluding the page i'm already on.
Then i'm using three foreach-functions to go through the projects i found, the tags they have and compare them with the tags of the project i'm looking at. If i have two identical tags, i count up a variable.
// Projects i have found
foreach($interessantes as $interessant):
$i = 0;
// Tags of the projects i have found
foreach($interessant->tags as $tag):
// Tags of the project i'm looking at
foreach($page->tags as $tagreferenz):
if($tag == $tagreferenz):
You can see what it looks like in the screenshot with a bit of HTML. I marked the tags of the current project green and the identical tags of other projects red with the amount of hits below. So in this example i would want to have three projects with three similar tags and get rid of those with only two and one.
I guess i have to put my pages into an array (with the number of hits?), sort them and echo them with "limit=3"? Unfortunately i have no idea how to do this. You probably have an even better/shorter solution. Links to other topics are welcome to and i'll try to get my head around it.
If you need further explanation, i'll try my best.
