As a WordPress developer, learning object-oriented programming has many benefits. OOP code can help organize and reuse code.

The
Last week, we looked at the basics of OOP. This tutorial will begin building plug-ins with new knowledge of object-oriented programming techniques. Let’s start with the basics of using object methods for structured change code. Compared with the platform using OOP, the third-party code of plug-ins and themes usually uses many \
Note: PHP is the basic language of WordPress, a high-level theme for developers in this series, so you must have practical knowledge of PHP. In this series, see code snippets. Especially in this tutorial, it is also important that you have a basic knowledge of creating plug-ins. Do you need help? Start developing the WordPress plug-in: please check the final guide. Create an object-oriented plug-in: for the purpose of this course, we will create a plug-in to add a subscription form after the content of a single post. The subscription form sends data directly to MailChimp. This is a simple problem, which can be easily implemented with program code, but it requires OOP method. The
This is an easy to see extensibility project. You can also add forms to other locations, implement working with other APIs, such as madmimi, or add data to a local database. How easy it is, I will know later. The program code first looks at the entire program code to understand what happened, and then performs structural adjustment to add OOP magic. To load the summary cb790e16c4aae22f91e32407c4dcd9c7, the front end needs to create a form and send the entered data to MailChimp. The msf_post_form() function handles the former. It connects the_content and returns the content as if it were not on a single page. The
Otherwise, admin Ajax. Create a form to submit to a PHP file. Two security elements have been added to the form. The most obvious is the nonce field, and the trickier is the honeypot name text field. This field will be disabled and hidden through CSS. I deliberately assigned a common name (as opposed to \
Finally, the msf_form_submit() > function is responsible for submission processing. After confirming nonce and honeypot, the remote publishing request will be sent to the appropriate location and the required data will be provided. For more information, see the MailChimp API documentation. Some additional checks are listed here, but this is not the main focus of this tutorial. The e-mail server also confirms that the server of API key and the server of URL (US6) match form adds several basic styles to the Tweety fifth topic. Load summary cb790e16c4aae22f91e32407c4
Easy to extend functionality. To add an age field, simply use your own plug-in or another plug-in’s filter. To add an age field to another plug-in, you can do the following: Another aspect of loading summary cb790e16c4aae22f91e32407c4dcd9c7 other extensible vendor applications is the vendor. MailChimp, madmimi, or other email list providers will provide excellent functionality. Instead of using the if statement in the commit processor, we will use a separate function to start the correct commit processor. We will recreate the configuration scheme and begin. The load summary cb790e16c4aae22f91e32407c4dcd9c7 displays the array. \
