Question

I am using the CodeIgniter framework and I am confused on how to remove %20 from my urls. Below is an example of my code.
Controller – blog
method – show
attribute – this is my blog

public function show($blog= null)
    {
    // my attempt to set the uri segment
    $blogName = $this->uri->segment(3, url_title($blog));
    ... //other code
}

this doesnt work, I am confused where I implement the url_title(‘this is my blog’) function so that on page load it shows:

/blog/show/this-is-my-blog

do I need to do something in the config/routes.php file?

thank you!

EDIT:

Alright so I found out that url_title() output this20is20my20blog so I now have this:

      $blogUrl = str_replace("%20", "-", $blog);
    $this->uri->segment(3, $blogUrl);

but it still returns the URL with %20

You just need to use the native php function urldecode to remove any characters that get encoded in a url. Spaces in a URL get encoded to %20 so instead of doing a str_replace just try

public function show($blog= null)
{
    // i'm not sure what url_title does so you might have to tweak this a little
    $blogName = $this->uri->segment(3, urldecode(url_title($blog)));
}
