Object Oriented Approach is beneficial over \u00a0Procedural Approach in terms of code re-usability, providing much more organised structure to code, etc. So we will learn a basic of WordPress Object Oriented Plugin Development.<\/p>\n

 <\/p>\n

WordPress Object Oriented Plugin Development<\/h3>\n

 <\/p>\n

So first of all we will start from initialising a class named WordPress.<\/p>\n

<?php\r\n\r\nclass WordPress{\r\n\t\r\n\tfunction __construct(){\r\n\r\n\t}\r\n\r\n}\r\nnew WordPress();\r\n?><\/pre>\n
Every class contains the “__construct” function. It is a constructor method for class based approach and “new” is used to create object of class.<\/p>\n
<?php\r\n\r\nclass WordPress{\r\n\t\r\n\tfunction __construct(){\r\n\r\n\t}\r\n\tfunction first(){\r\n            echo 'Hello World';\r\n\t}\r\n\r\n}\r\n$obj = new WordPress();\r\n$obj->first();<\/pre>\n
Now let’s say we have a function named\u00a0“first” and we want to get its content i.e. ‘Hello World’. So we will first create an object of class by using “new” and then we will call the function named “first” like $obj->first(), and it will simply print “Hello World”.<\/p>\n
If we want to get the contents of function “first()” in the beginning then we can simply call this function in our constructor as:<\/p>\n
<?php\r\n\r\nclass WordPress{\r\n\t\r\n\tfunction __construct(){\r\n\t\t$this->first();\r\n\t}\r\n\tfunction first(){\r\n\r\n\t}\r\n\r\n}\r\n$obj = new WordPress();<\/pre>\n
Now, as there are many predefined hooks in WordPress, so now a next pain\u00a0we face is how to load a function when the particular hook fires. \u00a0So here is the simple solution.<\/p>\n
<?php\r\n\r\nclass WordPress{\r\n\t\r\n\tfunction __construct(){\r\n\r\n\t\tadd_action( 'hook_name', array( $this, 'first' ) );\r\n\r\n\t}\r\n\tfunction first(){\r\n\t\techo 'Hello World';\r\n\t}\r\n\r\n}\r\n$obj = new WordPress();<\/pre>\n
