jQuery Datatables Implementation

jQuery Datatables

The jQuery Plugin Datatable will help you to keep those huge database results into a better and organize table. I have spoke of the jQuery Datatables plugin into this entry, so I will no use much time in the introduction of the plugin. I will focus and how you can get you database results into that Datatable.

For this Example I will be using a database, the employee table that I have been using in previous tutorials, so if you don't remember the file structure of the table I present it again.

Installing Oracle 11g R2 on WIndows 7

oracleAs many of you know Oracle is the top leader on Database Performance and Management, there are many databases on the market but believe me at my Job I work with thousands of records on Oracle, I mean thousands.

I am creating a PHP library to work with different databases, right now it includes connections for MySQL and Oracle, and this is why I am making this tutorial because before you connect to Oracle you must have it on you system.

Search with Ajax and jQuery UI Autocomplete, PHP, MySQL and JSON

Autocomplete Example

Autocomplete Example

I have been creating posts with scripts to do small stuff, but on this post I would like to show/teach you how to implement the jQuery UI Autocomplete Widget. I have to remark that for the style of the application I am using Bootstrap, so the most important thing is the html code of the form and the Javascript code. This is the Part 1 of the tutorial.

I would like to show you a diagram of the application flow so click it to enlarge.

Ajax usage to search a Record with PHP, MySQL and jQuery

I have created a few post about how to Search, Update and Delete data from a MySQL Database with PHP and PDO. Those tutorials are quite simple (but not dynamically enough, they don't use Ajax), but they are very important to catch the flow of this tutorial if you have never worked with this technologies. The tutorials are in Spanish so if you really need them in English I will be glad to translate them.

Something that I would like to remark is that you can get the scripts at the end of the tutorial.

In order to create a nice look and feel to the page I have implemented the framework Boostrap, but if you don't want to focus on the look and feel you only have to focus on the Form, the event to Fire the Ajax request and the server to process your request.

The next flow chart will show the path that we are going to cover to complete our Ajax search:
