Preventing RewriteBase - Deploy websites and apps on different locations
So I found a topic on stackexchange (for which unfortunately I can not find the link anymore) that had a question if it was possible to set up RewriteRules for sites in subdirectories. I found this to be an interesting topic, since I deal a lot with those kind of sites.

wp_page_menu forward compatibility with wp_nav_menu
You’ve styled your wordpress menu’s like the following:
#site-navigation li.menu-item-has-children { position: relative; } #site-navigation ul.sub-menu { position: absolute; min-width: 100%; top: 100%; left: 0; } /* etcetera etcetera */
However, when you’ve not set a menu for your menu locations, dropdowns no longer work, current menu items are no longer styled, etcetera, etcetera. How do we fix it?

WordPress gravatar / avatar bug: comment email instead of admin email
The following can happen:
- You make a site for a customer
- You insert some comments that your customer provides.
- Gravatar uses the admin email instead of the comment author email.
How do you get a gravatar image for the comment email instead of the author email?
You need to write a filter function. the get_avatar
filter passes the img code as first param, and the id of the author(you) or an emailaddress as the second.

Apache fallbacks without mod_rewrite
Just found out this awesomeness. In Apache 2.2.16 and higher, you can completely forget about mod_rewrite rules for your front controller:
RewriteRule ^.*$ index.php?url=$0 [L,QSA])
Apache has a tag called FallbackResource
:
FallbackResource /index.php
Woopdeedoo! Less code, more profit.
ModRewrite Shenanigans
So I am trying to figure out how to set up a router that can set up site hyperlinks that work with a mod_rewrite situation. I really like PATH_INFO
for this as I can use this for apps in subdirs (testing environment for example). This way, you can use http://domain.com/controller/action/1
and still have the fallback url working: http://domain.com/index.php/controller/action/1
.
If you place the following code in your htaccess, you can enjoy this technique.
#Force Path info in PHP, gets overridden in RewriteRule.
SetEnvIf Request_URI "^/?" PATH_INFO=/
# Mod Rewrite is off by default.
SetEnv MOD_REWRITE 0
<IfModule mod_rewrite.c>
# Update environment variable with some info.
SetEnv MOD_REWRITE 1
RewriteEngine On
# Webroot directory relative to index.php
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/?(robots\.txt|favicon\.ico|index.php)$
RewriteRule ^(.*)$ index.php/$1 [QSA,L]
</IfModule>
How does it work?
This way, you can use the following logic in your code to generate a correct url.
- Construct a variable to prepend:
- Take the directory name of the SCRIPT_NAME environment variable if the MOD_REWRITE environment variable is 1…
- … Or take just the SCRIPT_NAME environment variable.
- Add a trailing slash if missing.
- Add the url to a page you want or use the PATH_INFO environment variable for the current page (canonical links).
PHP Reverse Proxy
Just found this awesome proxy script: http://code.google.com/p/php5rp/ This is ideal for masking websites or storing your data on a different domain and faking the address. Yes, you can use a symlink, but this is a little safer.
Less mixin for fonts
So I developed a quick LESS mixin to generate font families.
I wanted it to use a local font on desktops if available, but not on Android devices, as they have have a bug where the smiley hack does not work.
A simple but smart dump(debugging) function using var_dump and func_get_args()
Every php developer knows the drill. Dumping debug info while developing. You either love it or you hate it. There are several solutions. In this post I will discuss those and suggest a lightweight alternative.
