Doesn't work with multisite

[royduin]

Hi,

I'm getting errors when I'm using WP-LESS with WP multisite. I've created a fix for it:

Replace line 87 in "Stylesheet.class.php" from: $this->source_path = WP_CONTENT_DIR.preg_replace('#^'.content_url().'#U', '', $this->stylesheet->src); To: $this->source_path = WP_CONTENT_DIR.str_replace('/wp-content','',parse_url($this->stylesheet->src,PHP_URL_PATH));

It would be nice if you change this in a feature version.

Have you tried https://github.com/sanchothefat/wp-less instead? It's the better plugin right now.

[thom4parisot]

There is an element of answer in #36. Is the proposed solution somewhere in the comments helpful enough to solve the problem?

I thought it has been added in the plugin's code but apparently I missed it.

[royduin]

@lkraav: Haven't tried, but is it possible with that one to update through Wordpress as well?

@oncletom: Sorry, didn't see it. As written in my first post, I've already fixed it, but I suggest to put my fix in the next version.

[thom4parisot]

Sorry I wrote the answer meanwhile you were editing. I thought this was fixed.

In any case, hardcoding to /wp-content is not a solution at all. I'd rather fix the content_url() substitution rather than making this change the way back.

[royduin]

But will this be fixed in a feature version?

[thom4parisot]

content_url() outputs the following.

If you could provide those 3 values, we could figure out how to address the problem nicely:

• $this->stylesheet->src
• content_url()
• $this->source_path for both scenarios (good and wrong one)

Thanks :+1:

[royduin]

The problem is that $this->stylesheet->src returns a full url so the preg_replace doesn't work.

[thom4parisot]

@royduin yeah I know but that does not help me to fix the problem :-)

Today I gave LESS-WP a try - but it doesn´t compile any less-files on my multisite installation, so what can we do to support for a fast solution of the problem?

[thom4parisot]

As stated above, I need to understand what is multisite configuration generating.

So if you could provide those 3 values, we could figure out how to address the problem nicely:

• $this->stylesheet->src
• content_url()
• $this->source_path for both scenarios (good and wrong one)

[gereby]

did anyone develop a solution to this so far?

[thom4parisot]

What does content_url() return for a multisite? Because it is supposed to be designed to handle both single and multisites install of WordPress.

[wtaeke]

Thanks @royduin - your fix is a lifesaver!!

[thom4parisot]

@wtaeke is there any chance you can tell me what is the value of content_url() for a multisite blog? Because /wp-content is a hardcoded value which can be changed through wp-config.php — opting for the aforementioned proposed change would break wp-less for those people.

Thanks!

Hi @oncletom, this issue is still present.

$this->stylesheet->src // http://example-b.com/wp-content/themes/theme-name/less/style.less content_url() // http://example-a.com/network-site-b/wp-content $this->source_path // C:\xampp\htdocs\example-a.com/wp-contenthttp://example.com/wp-content/themes/theme-name/less/style.less

Hope this helps.

I have my Network Site B mapped to example-b.com using WordPress MU Domain Mapping. Any chance to see a fix for this? Thanks!

[tyrann0us]

@oncletom Unfortunately this problem still exists in version 1.8.0. Could you please provide a bugfix? Thank you!

[thom4parisot]

please provide an bugfix

Please don't be rude, as this is not going to help.

[tyrann0us]

Sorry, I didn't want to be rude! Blame my bad english skills ;)

[thom4parisot]

In any case, for what I can see:

• $this->source_path value is incorrectly generated;
• content_url() and $this->stylesheet->src difference in tld makes it complicated to replace URL patterns.

A more flexible system is required. Like replacing the path from the value of WP_CONTENT_DIR (minus ABSPATH) to avoid dealing with absolute paths.

To be honest I don't have PHP nor wordpress installed on my machine anymore – you'll have to help me figuring out a solution. Try out if the following works.

$wp_content_dir = str_replace(ABSPATH, '', WP_CONTENT_DIR);

$this->source_path = WP_CONTENT_DIR.str_replace($wp_content_dir,'',parse_url($this->stylesheet->src, PHP_URL_PATH));

Note: it is wrong to hardcode wp-content folder as some people will customise this folder by altering the WP_CONTENT_DIR constant.

@oncletom I've got domain mapping on a multisite with external domains coming in, and I experienced the issue that this thread started with, and this code seems to have fixed the issue when replacing line 87 in Stylesheet.class.php with it. Probably not the most concrete fix, but it's a good patch for now

$this->source_path = WP_CONTENT_DIR.str_replace($wp_content_dir,'',parse_url($this->stylesheet->src, PHP_URL_PATH));

[schnoggo]

@oncletom Your proposed patch works fine. I'm running the "other" flavor of multisite (folder) and this solved the problem for me. Will you just roll it in, or do you want one of us to make a pull request?

[thom4parisot]

@schnoggo yes please, go ahead :-)

[schnoggo]

Set up some more sites on my test multisite and ran into further errors. @oncletom @TrevorMW : Any reason to not use get_stylesheet_directory() instead of basing off of WP_CONTENT_DIR?

[thom4parisot]

@schnoggo from the top of my head, this is what I tried but it had different behaviours between MU websites and non-MU ones. Or they did not provide exactly the same value.

I'm up for any solutions which works for MU and non-MU websites, with standard and custom WP_CONTENT_DIR values.

[schnoggo]

Here's a (sanitized) dump of what's going on:

$this->stylesheet->src: http:somesite.com/{sub-site}/wp-content/themes/{mainsite}/style.less $wp_content_dir: wp-content get_stylesheet_directory_uri(): http:somesite.com/{sub-site}/wp-content/themes/{mainsite} get_stylesheet_directory(): /dom13937/wp-content/themes/{mainsite} WP_CONTENT_DIR: /dom13937/wp-content ABSPATH: /dom13937/

So the catch is that enque is using a URI, but you need a local path to set/check the mod time of the file. How about if we calculate the wp-content path like you're doing, then preg_replace to get the part AFTER that (the path within the theme folder) and then tack those two together to get the local path?

Can anyone think of a case where that would cause a problem? Pretty sure any site in a multi-site will have the same wp-content path.

[schnoggo]

All of these solutions assume the path is in the theme folder... (Or at least the wp-content directory...) No one's tried it with external .less files? :)

[schnoggo]

Here's my proposed patch:

    // path to local content dir does not match URI in multisite.
    $wp_content_dir = str_replace(ABSPATH, '', WP_CONTENT_DIR); // get the 'wp-content' part of the path
    $lessfile_in_theme = preg_replace ('#^.*?' . DIRECTORY_SEPARATOR . $wp_content_dir . DIRECTORY_SEPARATOR . '(.*)$#', '$1', $this->stylesheet->src, 1); // the part after 'wp-content'
    $this->source_path = WP_CONTENT_DIR  . DIRECTORY_SEPARATOR . $lessfile_in_theme;
 //   $this->source_path =    WP_CONTENT_DIR.preg_replace('#^'.content_url().'#U', '', $this->stylesheet->src);

I tested this in a regular WordPress install, multisite (path-based) root site and multisite child site. I don't have an easy way to domain-based multisite.

@TrevorMW any chance you could try this patch your domain-based system?

[schnoggo]

@tyrann0us Could you see if this solves your issue? (If it does, I'll post a pull request right away.) Replace configurePath() around line 83 in /lib/Stylesheet.class

 protected function configurePath()
  {
    $target_file = $this->computeTargetPath();
    // path to local content dir does not match URI in multisite.
    $wp_content_dir = str_replace(ABSPATH, '', WP_CONTENT_DIR); // get the 'wp-content' part of the path
    $lessfile_in_theme = preg_replace ('#^.*?' . DIRECTORY_SEPARATOR . $wp_content_dir . DIRECTORY_SEPARATOR . '(.*)$#', '$1', $this->stylesheet->src, 1); // the part after 'wp-content'
    $this->source_path = WP_CONTENT_DIR  . DIRECTORY_SEPARATOR . $lessfile_in_theme;
    $this->source_uri =     $this->stylesheet->src;
    $this->target_path =    self::$upload_dir.$target_file;
    $this->target_uri =     self::$upload_uri.$target_file;

    $this->setSourceTimestamp(filemtime($this->source_path));
  }

I have same Problem with Multisite. I used Plugin "wordpress-mu-domain-mapping", so i can www.multisite.com/site1 -> www.site1.com mapping.

content_url() return http://www.multi.com/site1/wp-content, but $this->stylesheet->src is http://www.site1.com/wp-content.....

My solution ist use filter content_url

add_filter('content_url', 'content_url_for_less', 10, 2);
function content_url_for_less($url, $path = ''){
    $siteurl = site_url();
    if (stripos($url, $siteurl) === false){ //multi site with domain mapping
        $url = $siteurl . '/wp-content';
        if ( $path && is_string( $path ) )
            $url .= '/' . ltrim($path, '/');
    }

    return $url;
}

@sliu2016 Your solution totally worked for me!! I was freaking out, I owe you a beer :) Thanks a lot!

[tyrann0us]

@schnoggo after over a year I finally came back to this issue ... Your solution works for me, please make a PR! Thanks.
