We are closing down our forums, it’s time to move on, but we are keeping some important threads, here is one… I read about many of these points in books and tutorials but I was rather lazy to think about many of them initially learned some of these lessons the hard way. Fortunately I didn’t lose any major data over security issues with PHP MySQL, but my suggestion to everyone who is new to PHP is to read these tips and apply them *before* you end up with a big mess. If you are expecting an integer call intval() (or use cast) or if you don’t expect a username to have a dash (-) in it, check it with strstr() and prompt the user that this username is not valid. Here is an example: $post_id = intval ( $_GET [ 'post_id' ] ) ; mysql_query ( "SELECT * FROM post WHERE id = $post_id " ) ; Now $post_id will be an integer for sure JavaScript validation is only good to reduce the server load.
Use mysql_real_escape_string() to escape the user input. Then you can use it like this: deny from all Thanks! HTML5 Tutorial - Welcome.

Regular Expressions. IE7 Recalculated Offset Bug | CSS Class. IE7 now has support for dynamic pseudo classes :hover and is commonly used for the purpose of hiding elements from view and bringing them back into view when a ancestor element is hovered over, but the support is buggy depending on the property and values used for either hiding the elements or for bringing them back into view.
Setup: Container Absolutely Positioned Element What we have above is a container element containing an absolutely positioned element. The code will look like this. <div class="container">Container <div class="absolute">Absolutely Positioned Element</div></div> In the below examples, the absolutely positioned element is hidden from view by the normal position value and brought back into view by the hover position value.
Example 1: a.p element: normal position left:-999em; - hover position left:auto; Example 2: a.p element: normal position left:-999em; - hover position left:0; Example 3: a.p element: normal position left:-999em; - hover position left:auto; margin-left:0%; pForm - Free HTML Form Builder - Create Web Form Template Online.

The little bugs in it's CSS support still haunt us to this day. I still get comments from people who roundly reject any technique that doesn't work in IE 6. While I generally refuse to pander to IE 6's limitations, I still feel it is important to make things look right in it whenever possible.
Here are that major bugs in IE that'll get you every time: The Box Model This is perhaps the most common and frustrating bug of all in IE 6 and below. IE 6 will calculate the width of the box to be 100px. This kind of discrepancy can cause HUGE layout problems. I generally work around this issue by just not using padding on boxes I am using for layout. The Double Margin Bug Using our box example from above, let's say we need that floated to the right: IE 6 will double the 20px to 40px. I also like to side-step this bug whenever possible.

With the release of Internet Explorer 8, many customer sites suddenly had rendering errors and problems displaying the site correctly.
In order to avoid expensive and time consuming corrections Internet Explorer 8 has a new functionality called Compatibility View which enables the browser to emulate Internet Explorer 7. Internet Explorer 8 Compatibility View The question many customers asked is ”How can I force the client browser to use the Compatibility View when they visit our site? Web Developers and Site Administrators can configure IIS and their sites to tell Internet Explorer 8 to automatically Emulate Internet Explorer 7 when they visit their site or just specific WebPages.
This is done by adding a custom HTTP Header to the IIS and the website web.config or to add a meta tag to specific pages. X-UA-Compatible: IE=EmulateIE7 Pedro M. Textures.

A year ago, at a biggest-ever, record-breaking HTML5 Meetup in San Francisco all about WebGL, I predicted we were a tipping point; I think I was right. Let’s take a look at 2014, a banner year for 3D on the web! A Year of Great Content John Cale and Liam Young’s City of Drones brought together experiments in music and architecture; Isaac Cohen continued to blow minds with visualizations like Weird Kids and Webby; Google’s A Spacecraft for All chronicled the 36-year journey of the ISEE-3 space probe; and SKAZKA showed us an alternate world created by The Mill and powered by Goo. A Year of Killer Apps In 2014, WebGL made its mark– an indelible impression– on advertising, e-commerce, music, news and engineering.
A Year of Pro Tools Goo, Verold, Turbulenz and PlayCanvas all made great strides with their WebGL engines and development environments. A Year of Gaming WebGL is definitely up to the challenge of creating high-quality MMOs. A Year of Virtual Reality A Year of Ubiquity. Javascript Full Screen API. Posted at Paulund The full screen API is an easy way to get the full web content to be displayed on the page. It's very similar to pressing F11 on your keyboard but this can be done at the developers choice. This is a great feature to use for things on slideshows, you can make the browser go into full screen on a click of an image. The best thing about this feature is that it doesn't have to be the entire page, you can make any HTML element go full screen. Full Screen API support Unfortunately not all browsers support this feature so you need to make sure that your visitors browser supports this feature before you try to use it.
If the browser they are using supports this then you can use it, if the browser doesn't support this feature then you can make sure you do something else instead of using full screen. According to the website Can I Use the full screen API is currently supported on Firefox, Chrome/Safari and Opera. Check if the browser supports Full Screen API Exit the full screen. Ajax. Web Design Questionnaires, Project Sheets and Work Sheets. Advertisement It’s nearly impossible to provide an accurate quote to a prospective Web design client without first gathering information about what that particular client needs.
Some designers do this in either a face-to-face meeting or over the phone, but more often, they have a questionnaire that prospective clients fill out. This is preferable for a couple of reasons; the most important, is probably that this document then becomes an integral part of the design process and is available to refer back to. So the question is, whether you should put that questionnaire up on your website or only send it to prospective clients once they’ve contacted you. There are a couple of reasons you may want to make it available online, but the obvious one is that clients are often eager to get started with their projects; providing the questionnaire online eliminates a step in the pre-contract part of the process.

Your Internet connection's IP address is uniquely associated with the following "machine name": The string of text above is known as your Internet connection's "reverse DNS.
" The end of the string is probably a domain name related to your ISP. This will be common to all customers of this ISP. But the beginning of the string uniquely identifies your Internet connection. The concern is that any web site can easily retrieve this unique "machine name" (just as we have) whenever you visit. If the machine name shown above is only a version of the IP address, then there is less cause for concern because the name will change as, when, and if your Internet IP changes. There is no standard governing the format of these machine names, so this is not something we can automatically determine for you. Just something to keep in mind as you wander the Internet.

Interested? Let's get started. 1. Centering a Layout Centering an element is probably something every web developer has to do while creating a layout. Consider the Following Code: The output you'd expect: But what IE actually gives you: This is mainly due to IE6 in quirks mode and below not recognizing the auto value we set to the margin property. The Fix The easiest and most reliable way to center content for IE6 and below is to apply text-align: center to the parent element and then apply text-align: left to the element to be centered to make sure the text within it is aligned properly. 2.

Scanning The Internet With Nmap (Defcon 16) Description: How would you like to scan millions of hosts on the Internet and catalog all the interesting insights?
This is exactly what Fyodor, the author of Nmap or Network Mapper did last summer. Thankfully, he then went on to share his finding with the community at Defcon 16 in his talk titled "Nmap: Scanning the Internet". Interestingly, as Fyodor notes in his talk that scanning such a large set of IP addresses did help him in uncovering many bugs in Nmap and also forced him to make enhancements and add new features to make the scanner really fast. The slides for the presentation are available here and a high resolution video can be downloaded here.
