Resolving jQuery conflicts with other javascript libraries

admin — Thu, 16 Sep 2010 23:42:33 +0000

One of the reasons that make a software popular is its extensions and plugins. jQuery has plenty of plugins that do almost anything you want, from simple button hide to full blown galleries. Plugins let non developers easily add functionality they need to their websites and there are times when one might include more than one javascript library such as prototype.js, YUI or mootools with jQuery. They all use $ as their main function name. Including second library might brake the behavior of the first one. To resolve such cases jQuery introduces .noConflict() method.

When you call .noConflict() jQuery will return $() to it’s previous owner and you will need to use jQuery() instead of shorthand $() function.

Add the following code to your tag.

Unzip an uploaded file using PHP

I have been looking everywhere to try and find out how to do this. Some ‘solutions’ on the web left me at a dead end, but I finally worked out how to do it.

This is presuming you don’t have shell access to your server.

Simply create a file in the same directory as the ZIP file you wish to extract, and call it whatever you like. I use ‘unzip.php’.

Edit the file, and paste in the following code.

 open(’my_zip_file.zip’);
     if ($res === TRUE) {
         $zip->extractTo(’my_extract_to_dir/’);
         $zip->close();
         echo ‘ok’;
     } else {
         echo ‘failed’;
     }
?>

Change the name of ‘my_zip_file.zip’ to whatever your ZIP file is called. Then change the ‘my_extract_to_dir/’ to whatever directory on your server you wish to extract the ZIP to.

Once you have done, save the file and go to it through your browser ( http://www.youdomain.com/unzip.php ). If your browser echo’s out ‘ok’ then your file is extraced. If your browser echo’s out ‘failed’ you’ve filled in one of the bits of info wrong.

Basically it extracts the ZIP file into the directory you specify… make sure the directory you want to extract it to has write permissions.

Search Engine Optimisation for Beginners

Introduction

As most of you will already know, Google is rated by many as the number one search engine in the world. Infact, the term ‘Google it’ seems to have turned into an everyday phrase.

There are a few basic search engine optimisation techniques which I still see people missing. These simple additions should really be the first thing you would include to stay ahead of competitors.

The Right Keywords

Choosing the right keywords to base your site optimisation around is an important first step. General or generic keywords are usually not the best approach, and sometimes it’s better to be a little more specific and focus on niche keywords relating to your product or service.

Be specific, which means:

Targeting a more suitable market that is looking for a content editing solution
Competing with fewer websites targeting the same keywords
Optimising for keywords that people actually use when performing searches

Depending on your website, your products or the services you offer, you need to be specific with your keywords, and remember that people no longer use single keyword search phrases – the average search phrase contains 3-5 related words.

For example, if you’re optimising for a web development site and you’re located in Bradford, West Yorkshire, use keywords such as “web, development, bradford” or “web, development, west, yorkshire” would be a good start.

Remember, don’t keyword stuff!!!

Too many times have I seen website with the keywords such as “web design, web designer, designer, web, web developer, web site designer, web site developer”. This might look like you have lots of keywords geared toward web design, but believe it or not Google will not respond well to this and will mark you down for keyword stuffing. Why have a phrase of 14 words, when 3 will do.

URL and Title Tag

These are two of the most determining factors in Google’s ranking. For example, a domain name such as: http://www.webdevelopmentbradford.com will generally get ranked higher than http://www.companyname.com, assuming that they had identical keywords and page content.

Your title tag is equally as important as your domain name. Using keywords in your title tag can improve your Google ranking significantly. For example:

”Company name, affordable web development services in Bradford, West Yorkshire”

H1 Tags and Keyword Density

tags seem to have been depreciated by stylesheets these days, and are not used as often as they used to be. The Google ranking algorithm dictates that if you’re using a

tag, then the text in between this tag must be more important than the content on the rest of the page. Here’s a quick example:

Sprinkling keywords throughout your page content can also improve your sites keyword density. Keyword density means the ratio of optimised keywords to the rest of the content on your page. It is usually expressed as a percentage, and should be between 7% and 10% for each page on your site. There are a few sites out there to help you along with making sure you’re not keyword stuffing, but in my opinion www.rankingtoday.com is definately a tool to have in your arsenal for Search Engine Optimisation.

Links, Links and More Links

Back links are websites that link directly to your website. The general principal is the more back links you have, the higher your pages will be ranked, as your website must be good if so many other sites are linking back to it.

One of the easiest ways to get backlinks if you run a web development company is by simply adding a simple link to the bottom of each of your client’s websites, with your clients permission of course, such as:

Web development by Company Name

Validate your HTML

One thing people overlook is that there HTML doesn’t validate. While this isn’t always a major worry, if you want to get further up the search engine let get tidying up. Use the W3C Validator to check if you have any errors in your HTML. If you do, find out what they are from the report and fix them. Depending on how many errors you have, it shouldn’t take too long to resolve them and it will benefit your site.

Conclusion

People say “Google is a tough search engine to crack”. Truth is, its not (as long as you do as Google likes, and steer clear of hinderances). Hopefully I provided you with the basic tips to get started optimising both yours and your clients website.

Lunascape Web Browser, perfect for cross-browser developing

admin — Tue, 24 Mar 2009 14:01:37 +0000

Whilst stumbling around the web the other day, I came across a web browser called Lunascape. Having not heard of this before, I read through the browsers features.

Impressed with what I read about the different rendering engines built into one, and that is it the ‘Fastest Browser’, plus getting 100 / 100 on the Acid 3 test, I decided to test it out.

Switch Rendering Engines

Thats right, three different rendering engines built into one browser. Internet Explorer’s Trident, Firefox’s Gecko and Safari’s / Chrome’s WebKit all incorporated the ability to switch between rendering engines can allow web designers/developers to avoid browser specific issues with certain web sites.

Fully Customizable with Skins

Skins can be installed very quickly and easily, and with 200+ to choose from, you can personalise to your hearts content. To be fair, some of the skins are a little tacky, but there are a few cool ones in there too.

Abundant Plug-ins

Lunascape have a vast library of plug-ins available to further expand the potential power of this browser.
