Single PHP error page to handle all response headers / errors

There might be an easier way of doing this but i’ve been working on a project which needed the following which i have done as a simple single php page and thought i’d share it in case anyone wants to do the same thing.

  1. Error page generated by dynamic pages
    (using any code; 403, 404 etc)
  2. Error page to handle genuine errors
    (404 ‘Not Found’, 403 ‘Forbidden’ etc)
  3. Forbid visitors from visiting sensitive areas/directories
    also returning 403 ‘forbidden’ header.
    (e.g. /images, /css /javascript, /ajax etc)

Download all these files: http-error-code.zip

instructions for use are commented within the error.php code but in summary:

You need to create a .htaccess entry for each error code:

Code for .htaccess:


ErrorDocument 403 /error/error.php
ErrorDocument 404 /error/error.php

For forbidden folders just add this code into a file called index.php then put this file into the folder that you want to forbid directory listing for:

Code for index.php:

<?php
// Set response code
$error = 403; //Forbidden
// include the error page (
include ($_SERVER['DOCUMENT_ROOT'].'/error/error.php'); // assuming "/error/error.php" is the location/name of this file
// stop processing the current page
exit();
?>

Save this code to a file called error.php and save to yourdomain.com/errors/error.php

Code for error.php:

<?php

To generate response from another page, as a result of incorrect database query or invalid content etc just add this code:
(make sure no page output has been generated before this include)

<?php
// Set response code
$error = 403; //Forbidden
// include the error page (
include ($_SERVER['DOCUMENT_ROOT'].'/error/error.php'); // assuming "/error/error.php" is the location/name of this file
// stop processing the current page
exit();
?>

-------------------------------------------------------
TIP:
-------------------------------------------------------
Hide the default directory listing for a folder
e.g. /images, /css, /java etc.

1. create a blank file called index.php
2. paste the php code above into the file
3. place it inside the folder

// THE CODE...
// ------------------------------

// if the error code has been set by referring page:
if ($error <> ""){

$code = $error;
} else {

$code = $_SERVER['REDIRECT_STATUS'];
}

// set $path variable to the requested path/uri
$path = $_SERVER['REQUEST_URI'];

// Create array with error codes and messages
// You must add a line to .htaccess for each code used here.
// e.g.
// ErrorDocument 403 /error/error.php
// ErrorDocument 404 /error/error.php
// etc...

Google’s New Sitelinks

Sitelinks have been around for a while but used to look like this:
Old Style Sitelinks

Now they look like this!:
New Google Sitelinks for Microsoft
Within Google’s new search hierarchy, sitelinks will now be full-size links with a URL and a line of snippet text, similar to regular search results. But Google has also designated a maximum number of 12 sitelinks per search result, giving pride of place within the page to the first search result.

The changes will roll out globally to all modern browsers, including Chrome, Firefox, and Internet Explorer 7 and above, Google said.

Sitelinks are useful to users as they may not be able to specifically identify where in a site they want to visit, so he or she merely types in the overarching domain.

“It turns out that sitelinks are quite useful because they can help predict which sections of the site you want to visit,” Daniel Rocha, a software engineer on the Google Sitelinks team, wrote in a blog post. “Even if you didn’t specify your task in the query, sitelinks help you quickly navigate to the most relevant part of the site, which is particularly handy for large and complex websites. Sitelinks can also give you a good overview of a website’s content, and let webmasters expose areas of the site that visitors may not know about.”

Google has also said that it is tweaking its search algorithm to accommodate the changes. “In addition, we’re making a significant improvement to our algorithms by combining sitelink ranking with regular result ranking to yield a higher-quality list of links,” Rocha said. “This reduces link duplication and creates a better organized search results page. Now, all results from the top-ranked site will be nested within the first result as sitelinks, and all results from other sites will appear below them.”

Don’t want to sign into messenger when using hotmail?

I discovered that when using hotmail on my new Windows 7 laptop it automatically signs me into msn / live messenger. After trying to find a setting somewhere to disable this feature i have finally found it (and it’s really very easy)…

I discovered that all you need to do to stop messenger logging in every time you check your email, just log into hotmail as usual, click your name in the top right, or open the messenger list and click “Sign out of messenger”.

How to stop MSN / Live Messenger loading in Hotmail

This will permanently sign you out of messenger in hotmail, and only hotmail.
If you are logged in on the normal desktop app you will stay logged in.

If you sign out / close your browser and sign back in to hotmail, messenger won’t load leaving you free to check your emails in peace!

Change Juitter Time and Date Format

As you can see in the sidebar on the left i am using Juitter to retrieve my twitter feed, I didn’t like the default juitter date format because it’s rather long (“ddd,dd mm yyyy hh:mm:ss +0000”)

Here’s how you can reformat the default juitter time and date format…

Just insert the code below into the “jquery.juitter.js” file, underneath the line “var tweet = $.Juitter.filter(item.text);”

// Re-format Date/Time
//get Tweet date
var d=new Date(item.created_at); //Default date/time is when the tweet was published
var tweetdate=d.toLocaleDateString(); //rewrite date in a nicer way
//get Tweet time
var t=new Date(item.created_at);
var tweettime=t.toLocaleTimeString().substr(0,5); //rewrite and remove seconds
//pull it together
var timestamp=""+tweetdate+" at "+tweettime+"";
// Reformat Date/Time

Then in the few lines below this newly inserted code (the code that generates the HTML) replace “item.created_at” with “timestamp”

Simple!

If you’re on Twitter why not give @iamnotaspambot some love using the hashtag #iamnotaspambot and he will try and give you a little bit of twitter love in return.

Facebook too slow? try Facebook Lite, the low-fat facebook

This lite version is now now longer available, Facebook decided to remove it.

That’s right, Facebook Lite, a stripped-down version of Facebook that shrinks Facebook down into its core features, making for a much smoother facebook experience.

This new version of the site is much more simple and cleaner in appearance and appears to be a better site for Facebook newbies or for anyone who finds the current site “too much” or noisy. It also does away with the old-school Facebook apps, which is just as well for the newest Facebook-connected services. (although farmtown/farmville addicts will still have to use full-fat facebook to harvest and plow!)

The major visual change in Facebook Lite, compared to the full-fat Facebook “Classic,” is simply that most of the the navigation and info page that was on the left of the page is now gone. The user is not distracted by the mostly superfluous details that resided there. The input box is also gone, replaced by buttons (Write, Post Photos, Post Video) that pop down the actual input forms only when needed.

The facebook chat feature is in there too, it’s not embedded in the facebook page but as a separate “pop-up” window instead.

Anyway enough from me, check it out for yourself… lite.facebook.com

…enjoy!
