What path do I use to call a background image in codeigniter

问题

This is my root structure:

And under the folder css, I have the file style.css

I load my CSS file like this:

<link rel="stylesheet" href="<?php print asset_url()?>css/style.css">

I created a helper asset_url_helper that has this function:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

if ( ! function_exists('asset_url()')) {
    function asset_url()
   {
    return base_url().'assets/';
   }
 }

And my .htacces file:

Deny from all
RewriteEngine on
RewriteCond $1 !^(index\.php|images|assets|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

Loading the CSS file works like a charm, thats no problem.

Now I want to call a background image from my style CSS something like this:

body {
    background-image: url('/assets/img/bg-admin.jpg');
}

But this doesn't work

Can someone tell me how I call the image file from CSS?

回答1:

background-image: url() in CSS works relatively.

Try this:

body {
    background-image: url('../img/bg-admin.jpg');
}

This is assuming that your css file is in assets/css and not a sub folder of it.

Hope this helps!

回答2:

codeigniter will take the base_url. your url is http://localhost/rscms/external/bootstrap/css/style.css you will to go back to bootstrap first come out from style.css then css then bootstrap

background-image: url('../../../img/bg-admin.jpg');
