// wrap print_r in preformatted text tags 
// usage: print_pre($value)
function print_pre($value) { 
    echo "<pre>",print_r($value, true),"</pre>";
}

Basically, using print_pre (if the name doesn’t collide w/ another function in your program) will work just like print_r except of course wrap the output in preformatted text tags <pre>.

I do a lot of work in WordPress so if you can just drop this into your functions.php file if you’d like to use it. The same goes for Drupal, add it to your themes file for easy access. Another option I supposed would be to prepend it to your PHP documents but I’m just speculating right now and that could turn out not so good.

Anyways, print_pre can be used in place of print_r to dump output of print_r pre wrapped in pre tags.

This is probably the better long term solution:

#content {
        background-color: rgba(255,255,255,0.3);
}

Then, you’ll of course need to make an exception for stinkin IE:

<!--[if IE]>
   <style type="text/css">
    #content {
        background:transparent;
        filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#44FFFFFF,endColorstr=#44FFFFFF);
        zoom: 1;
    }
   </style>
<![endif]-->

In the case above, I’m using Microsoft’s gradient, but just going to and from the same color. I’ve wrapped the rule in an if statement and this goes somewhere in after the rest of your CSS has loaded.

I’ll need to do more testing on versions this works with, but for most non-ancient browsers, this works. Looks easy now, but taking so long to get this far, I’m writing this down before it goes down the memory hole and I’m stuck having to figure it all out again.

Special thanks to the following posts, and especially the first on this list:

• CSS Background Transparency Without Affecting Child Elements, Through RGBa And Filters
• Playing Around With CSS3 Colors
• Cross Browser Opacity
• RGBA Colors – CSS3

That’s it for now. This is how I’m getting cross browser css transparency on elements without the transparency being applied to the content.

Edit: Now that I have of course written blog post about this I’m coming across a ton of similar work. Below is a Smipple from joost.kiens which is much simpler that my solution (all styling is handled in a single element without the need for isolating IE):

.rgba {
  background-color: transparent;
  background-color: rgba(200,200,200,0.8);
 filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#99dddddd,endColorstr=#99dddddd);
  -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#99dddddd,endColorstr=#99dddddd)";
}

Well, I eventually found out how to make the phone number a required field in PayPal Express Checkout. These are the steps:

Login => goto My Account => select Profile =>
select ”See the classic Profile version” (the new stuff is garbage)

PayPal => My Account => Profile

Select “Website Payment Preferences” under Selling Preferences

Select Website Payment Preferences

Select radio button “On (Required Field)” under Contact Telephone Number

Select "On (Required Field)"

That’s it. That’s how you can either require or set optional a contact telephone number in your Paypal Express Checkout account.

As a reference, and after far too long searching, I found the documentation on a seemingly obscure developer document at: https://www.x.com/docs/DOC-1367. You’ll find the instructions (the same as I gave) under the heading “Require a Contact Phone Number”.

OPTIONS * HTTP/1.0″ 200 – “-” “Apache/2.2.3 (CentOS) (internal dummy connection)

The definitive explanation for this issue can be found at the link below, however, it does not detail the method to follow for servers setup for ipv6 (which is what my post documents):

http://wiki.apache.org/httpd/InternalDummyConnection

What you can do is simply ignore the errors by adding a few lines to your apache conf files:

# Custom Conditional Logs
# Reference: http://httpd.apache.org/docs/2.2/logs.html Conditional Logs
#
# Mark requests from the loop-back interface (internal dummy connection)
SetEnvIf Remote_Addr “::1″ dontlog
SetEnvIf User-Agent “.*internal dummy connection.*” dontlog

You’ll then add dontlog to the end of logfile directive (which may look something like this):

#
# For a single logfile with access, agent, and referer information
# (Combined Logfile Format), use the following directive:
#
CustomLog logs/access_log combined env=!dontlog

Basically, you’ll just need to ignore these internal requests by blocking the local Remote Address. You can reference Conditional Logs at:

http://httpd.apache.org/docs/2.2/logs.html

That should help.

After doing just a few minutes research on this post of List of WordPress Plugins Lists I’ve quickly come to the conclusion that these lists (of WordPress Plugins) most likely are the most popular lists (of any topic) out there on the internet.

Happy listing and remember, there is no such things as List Overload.

httpd not running, trying to start
(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

In my particular case, this stinker of an issue arises due to my SSL Certificate requiring a pass phrase. Since during reboot that pass phrase was not provided, Apache could not start.

So, after seeing the error above you’ll need to check what is currently listening to port 80:

netstat -lnp | grep :80

If you see a process running, kill it using:

kill -9 pid (where pid is the numeric process returned above)

You can now try and start/restart; I use:

/usr/sbin/apachectl graceful

Then, you’ll see that Apache is now trying to successfully start. You’ll see something like this:

httpd not running, trying to start
Apache/2.2.3 mod_ssl/2.2.3 (Pass Phrase Dialog)
Some of your private key files are encrypted for security reasons.
In order to read them you have to provide the pass phrases.

Here is where you provide the prass phrase.

I think the next thing to do is to remove the pass phrase from my SSL Cert (there’s a good writeup for that which I need to dig up for this post), but in the meantime, this is how it’s handled.

However, what I’m really looking to do is basically swap in one of my own functions for a WordPress Core Function. It seems that WordPress’ Pluggable Functions allows me to do that:

• http://codex.wordpress.org/Pluggable_Functions

The explain it a bit here:

Pluggable functions were introduced in WordPress 1.5.1 These functions let you override certain core functions via plugins. The most up-to-date list of core functions that WordPress allows plugins to override is available at wp-includes/pluggable.php. WordPress loads the built-in functions only if they are undefined after all plugins have been loaded.

Now, this only allows you to replace a limited number of WordPress functions, but it does, what it says it does, and that is to allow you to replace a core WordPress function by using WordPress’ Pluggable Functions.

Incoming search terms:

• wordpress override function
• wordpress replace function
• wordpress override core function
• wordpress override plugin function
• replace function wordpress
• wordpress replace functions
• wordpress redefine function
• override wordpress function
• override plugin function wordpress
• overwriting wordpress function

What I did was to add the extension and mime type to the following functions in the WordPress functions.php file:

• function wp_ext2type
• function get_allowed_mime_types

The proper method for adding this Mime type would be to add via a Plugin so that any upgrades do not wipe out your changes. However, I was willing to deal with this, but reportedly the following plugin will help:

• PJW Mime Config

So, basically that’s it. That is how I added the mime type and extension information to allow the WordPress file/video uploader to successfully upload the Flash video type with extension f4v.

The following pages were helpful with this issue:

• WordPress: File type does not meet security guidelines.
• WordPress Accepted Filetypes
• New File Extensions and MIME Types
• Mime type for flv

I’ve got an update to this post. I’m now adding this Flash f4v mime type to WordPress via my theme’s function.php file. It follows and adds to some of the links above explaining how to add a mime type to WordPress.  Most tutorials explaining how to add a mimi type to wordpress stop at the adding it to the function get_allowed_mime_types, this snippet adds the mime type to the wp_ext2type function as well:
