As a layman’s language, the WordPress plug-in is a simple program that can help users customize and improve the WordPress website without editing the core programming. After mastering the WordPress plug-in development, you can immediately add all the functions to the wordpress blog. But before you can become a professional player, you must learn ropes. WordPress plug-ins are programs written in PHP scripting language or one or more feature sets. They use access points and methods to add specific features or service sets to WordPress web logs for seamless integration with web logs. The WordPress plug-in API (application interface) provides Create a plug-in, WordPress Codex
Today’s post will guide you to create the first word press plug-in. This tutorial is reserved for the first developer who has little or no knowledge of PHP (the scripting language behind WordPress). However, before we start the actual coding, let’s take a look at some things we need to know about WordPress plug-in development. Basic knowledge you need to know before creating a WordPress plug-in this section describes the first few steps you should follow when creating a WordPress plug-in. In addition, we will discuss various factors to consider when writing plug-ins. It’s big. Start with the foundation. The
To specify the name of the WordPress plug-in, you must first find the unique name of the WordPress plug-in, not any other name. One of the best ways to determine friendly names is to consider what the plug-in will do. For example, if the plug-in helps people share content through social media, the name may include the word \
To specify the name of the plug-in, you must create at least one plug-in file (the main PHP file), which describes the next section. The method of creating a plug-in file a plug-in can consist of a single PHP file or multiple files, depending on the designed operation. The most important file is the main PHP file, which is indexed in the word press theme and HTML design respectively. PHP and index. HTML. WordPress developers recommend naming the plug-in according to the rules and naming the default plug-in file. For example, the default plug-in file for a plug-in named WP renym plug-in is WP renym. PHP. If you add a separator to a name, use the hyphen (–) only between words that are not underlined (_). The
As mentioned above, a plug-in can be a single or multiple file (image, JavaScript, language, CSS file, etc.). Either way, the plug-in files must be in a single directory. Therefore, for the wprenym plug-in, WP renym. The PHP file is placed in the WP renym folder. You can add additional subfolders to the default plug-in folder to include and configure additional files. After placing all the code for the plug-in, compress the default folder into a zip file (in this case, the wp-renym.zip archive file), upload it to the WordPress site and install it. The
When you specify the plug-in name by adding the file header to the main PHP file, you must add additional details such as description, version, license, and author name. By default, all plug-in headers displayed on the WordPress plug-in screen are plug-in headers. to this end
The standard plug-in header must be used at the top of the default PHP file. Typical headers are as follows:\/* Plugin name: name of your plugin plugin uri: http:\/\/link To your plugin homepage description: describe what your plugin is all about in a few short sentences version: 1.0 author: your name (yay! Here comes fame…) Author uri: http:\/\/link To your website license: gpl2 etc license uri: http:\/\/link Toyour plugin license*\/ all parameters in the above header need to be described, so we won’t discuss details. When creating plug-in and author URIs, you must include the relevant http:\/\/ or https:\/\/. Otherwise, the link will not work. The
If you want to use a gpl2 license or a gpl2 compatible license, follow the following license information in the header:\/* Copyright year plugin_author_name (email: your email address) (plugin name) is free software: you can redistribute it and\/or modify it under the terms of the GNU General Public License as published by the free software foundation, either version 2 of the license, or any later version (plugin name) is distributed in the hope that it will be useful, but without any warranty; Without even the implied warranty of mercury or fitness for a partial purpose See the GNU General Public License for more details You should have received a copy of the GNU General Public License along with (plugin name) If not, see（ http:\/\/link To your plugin license)*\/ The scope of this tutorial is not allowed to go beyond these basic steps. To learn more about WordPress plug-in hooking, template labels, storing plug-in data in the database, plug-in option mechanisms, and plug-in updates, make sure to create a plug-in guide in Codex. Codex also contains a large collection of plug-in resources, including video guides, advanced topics, and so on. The
Now that we’ve covered the basics, we’ll write a simple word press plug-in that performs two basic (but cool) functions. Replace the words in the content with the required words, and write at the end of all blog posts: \
Continue… Open the new file in the code editor. Our PHP function is a ($text) parameter. The first string \
Replace and return to WordPress. Add a filter to the plug-in to instruct the function (renym_wordpress_typeu fix) to work in the text we select (in this case, the full post content). To replace multiple words (you may want to edit multiple words in your blog or use the plug-in as a simple abuse filter), replace the above code with the following code: Function renym_content_replace ($content) {$search = array (‘wordpress’,’good’,’east’,’70’,’sentimental’); $replace = array (‘wordpress’,’coffee’,’east holidays’,’seven’,’extraordinary’); return str_replace ($search, $replace, $content);} Add\u filter (‘the\u content’,’renym\u content\u replace’); In the above code, we have selected words to replace WordPress, goat, Easter, etc. We also chose alternative pronouns such as WordPress, coffee and Easter holiday. I hope the code is a little self explanatory. The renym_content_replace function replaces all words contained in the ($content) $search array with parameters, and returns the currently modified word to WordPress$ Search contains all words to replace$ Replace contains the replacement word. Str_replace replaces a word with a new word to perform the best action. Notice how to add the prefix renym to all functions. This prevents conflicts with other plug-ins that may be installed. When developing plug-ins, themes, or artifacts, you should get used to adding prefixes to functions. After completing the above steps, the plug-in can effectively replace all the selected words. \
Just right-click and zip the file. I think it’s very similar on a PC). Documents. Make sure that it is stored as a zip extension. Otherwise, the plug-in will not be installed. Use the plug-in to upload and activate the new WP renym plug-in through the WordPress plug-in screen. Congratulations on creating your first plug-in!
