Hi! In this tutorial we will see how to submit form using jquery ajax and php without page refresh . Web Development enhanced with AJAX increases speed and performance thereby improving the overall user experience. It allows you to update part of a web page without refreshing it completely. Basically, when you submit an html form, the entire page will be refreshed. But by using ajax technique, you can submit the form to the web server without having to reload the page. Instead, the form data will be submitted to the server in the background and can be processed in any way you want. How to Submit Form using jQuery AJAX and PHP?

Hi! In this tutorial let's look at the server-side processing of jquery datatables using php, mysql and ajax . In case you don't know, Datatables is an amazing jquery plugin that converts the simple html table into a feature-rich data grid with additional functions like instant search, pagination, multi-column sorting etc. The table works with multiple data sources like DOM, AJAX etc., and supports both client and server side processing. We have already seen about datatables with json data and here we will see about server side processing. For the server script, we are going to use PHP and MySQL as a data source. jQuery Datatables Server-side Processing with PHP and MySQL: Let's see how to fetch records from the server-side using ajax request and list it in the data tables.

Today let's see how to filter array by value in php . When working on a large data set, it would be useful to filter array values based on conditions. For this, you must iterate through the array, check each element against some condition and decide to keep it or discard it. It is a task that takes a lot of time to say. Luckily you don't have to fuss over this. With PHP's native array_filter() function, you can filter the array using callback where you can specify the condition to filter each element of the array. The function returns the array containing elements that are successfully passed through the callback. Using Array_Filter in PHP: The function array_filter() filters elements of an array using a callback function. array_filter(array, callback, flag) The function takes up three parameters of which the first one is mandatory and the rest others are optional. array - The array to be filtered callback - The callback function to use as a conditional fi...

Hi! In this tutorial, we'll see how to connect to multiple databases using PHP's MySQLi and PDO (PHP Data Object) library. At times you may want to work with multiple mysql databases in the same context. Therefore, you need to connect to two or more databases in the same mysql instance and fetch data from them simultaneously. The old 'MySQL' extension has been deprecated since PHP5.5, so I would recommend you to use 'MySQLi' or even better 'PDO' , which provides an additional layer of security and supports multiple databases such as MySQL, MSSQL Server, PostgreSQL, Oracle and much more. The databases can be on the same server as php script or on different server. No matter what, connecting php to remote mysql server is similar to the one on the same server, except that you must provide permission to access the remote database. Connecting Multiple Databases with PHP MySQLi: Establishing connection to multiple databases using mysqli api is eas...

Hi! Today let's see how to get address from latitude and longitude using PHP and Google Maps Geocoding API . In general, the process of converting geometric coordinates such as latitude and longitude into address is called reverse geocoding . And the geocoding is just the opposite, converting address into latitude and longitude which we have seen in our previous tutorial. Google Maps provides a separate Geocoding API for the purpose and let's see how to use it with php. To obtain physical addresses from the API, you have to send http request along with latitude and longitude values. Getting Address from Latitude and Longitude using Google Maps: To access Google Maps Geocoding API , you need an http interface through which you can send and receive an http request/response from the api. Here is the sample request you should send to the web service. http://maps.google.com/maps/api/geocode/json?latlng=40.6781784,-73.9441579 The 'latlng' parameter must be used t...

Hi! In this tutorial, let's see how to get latitude and longitude from address using google maps geocoding api and php . Geocoding is the process of converting physical addresses into geographical coordinates such as latitude and longitude so you can use them to create markers in Google Map. It is also better to provide latitude and longitude when using Google Map API so that you can point to accurate position on the map. To obtain the geocode, we must send an http request to the Google Map Geocoding API along with the formatted address. How to Get Latitude and Longitude from Address? The Google Maps Geocoding API is a web service used to obtain geocoding and reverse geocoding of the addresses. And you have to access the api through the HTTP interface. Here is the sample request you have to send to Geocoding API to get latitude and longitude coordinates. The API provides a response in both json and xml format.

Arrays are generally used to store and manipulate data with ease and known to be one of the core building blocks of PHP Programming . When properly used, arrays are a great tool to process large amount of data efficiently - be it from database server or from a third-party source. But they can become nasty once you start working with multidimensional array which by itself is an array of arrays i.e., every element of the array turns out as an array. Below example is a good representation of a multi-dimensional array. PHP Multi Dimensional Array $color = Array ( ('r') => Array ( ('red') => 255, ('green') => 0, ('blue') => 0 ), ('g') => Array ( ('red') => 0, ('green') => 255, ('blue') => 0 ), ('b') => Array ( ('red') => 0, ('green') => 0, ('blue') => 255 ) ); ...
