Building dynamic forms is a task that a lot of web developers will have to do at some point. By dynamic I mean forms that change based on what the user inputs.
A basic example of dynamic forms, are those that allow the user to add the same group of information several times. For example, an attendance form, where you can add several persons, a booking form where you can add several tickets, a membership with several users, a media page with several pictures or videos and so on, the possibilities are countless.
In order to facilitate the development of such forms, I created a little plugin, that allows you to dynamically clone a specific set of information that will be repeated. So if you ever searched a way of cloning forms, fieldsets or groups of input, this could really be helpful.
For the previous years I've been trying to point out the areas of my workflow that were taking most of my time to try to optimise them.
One of these areas was database interactions meaning the famous 'SELECT', 'INSERT', 'UPDATE' and 'DELETE' statements. When I was still discovering PHP, I spent far too much time hard coding every single database query. It was time consuming, but also very annoying.
Then, for a project, I discovered Zend, a powerful PHP framework. I loved the way it handled the queries, by having a database class with predefined methods for each interaction. The only problem was that Zend is far too bulky and complicated for simple projects.
After investigating if there were easier ways of achieving the same results, I am presenting here today a list of my favourites mysql functions, with their brief description and how you can use them. I hope that it will save you time in your future developments like it did for me.
RSS is a way of easily keep your site's readers up to date with your latest content. That's a reason why it is widely used by the famous blogs and big sites. Once someone subscribes to an RSS feed, he'll get a notification every time you post some new content to your site. It helps fidelizing your users, therefore improving your traffic. It is definitely worth implementing. This tutorial will guide throught the steps involved in the creation of your own RSS feed from scratch, and based on your site's existing platform.Read more
Even on some very famous websites and blogs based on the WordPress platform, such as Smashing Magazine or Webdesigner Depot for example, the comment forms are not checked prior to submission. Which means that if the user hits the submit button without actually filling any information, he is redirected to the famous error: "Error: please fill the required fields (name, email).".
Thanks to jQuery and its plugins, it is possible to change the way those forms are handled, in order to obtain slick effects, and an overall better user experience.
In this tutorial, we'll associate the validation plugin, and the form plugin, to get a contact form that is validated before submission, and submitted via ajax. Why don't you give it a try?
It's now quite common to swap the old url format containing file extensions and non explicit query strings by SEO friendly ones, only made of keywords and slashes, hence their name.
There are several techniques to do so, and I certainly do not have the pretention to say that this one is the best of all, but it is the one I use in personal projects as it works nicely, and it is robust and dynamic.
It makes use of an .htaccess file to rewrite the urls, of a php function to parse the given parameters, and a content manager to serve the appropriate content according to them.
Before we start I'd like to make a personal thanks to Josh Moont for his precious help.
