Let’s create our own WordPress plugin with the fastest way – where we will use write our custom hack codes.
And i will give a link to this article in the next tutorials when we need to add new code from new article to be added to our website.
In WordPress Codex you can get how to create plugin, there are a lot of template strings which you should change. But actually we don’t need most of them,
To create your own simplest WordPress plugin you just need a single file and name in it.
- Create new file in wp-content/plugins folder.
- Put the single line
/* Plugin Name: My Custom Plugin */ to it
- Go to wp-admin/plugins and activate the plugin “My Custom Plugin”.
That’s all with the creating.
But how will we use it for our own purposes?
Let’s add our first useful code and see how it works. In the future articles we will add more useful codes to this plugin.
Let’s add Google Analytics support to our WordPress website. For that we should add Google Analytics code to our website’s footer or header section. Let’s add to header section.
That’s all. With this simple code Google Analytics code will automatically be added to the all pages of our WordPress website.
If we want to use external mail servers for sending mails via our website, we can do it without any plugin.
And also we can build simple function which can use several mail servers for each case.
For example, it may use different mail server when it sends something via cron jobs, another mail server when it send something via contact form etc..
It is not about to change email headers like “email from”, “sender name” – to do it is much easier.
I mean real external mail server with different mail server hostname, port, user and password.
1. In first one it gives a code to use single external mail server.
2. In second one it gives ability using randomly chosen multiple mail servers. (could be helpful when mailservers have some sending limits)
3. In third one it gives ability chosing mail servers for specified cases.
If you want to check this inside the some hook, which runs after plugins_loaded hook, it is very simple. Just check some plugin specific constant or function exists or not.
For example, to check WooCommerce we will need to check any WOO constant is defined or not. Or it is enough to check if class WooCommerce exists or not.
But what if you want it to check it before the plugins loaded? In this case you will not be able to check some constant,function, class of the plugin is defined or not, because they are not loaded yet. So we will need some additional trick for that. We can check $wpdb->options table and get the list of active plugins, process it and get the results. Let’s see how it works.
Here is sample code for that:
Backend gets the first requests and does some operation and returns done percentage. (in this sample there should be 10 steps, so each requests completes the next 10%).
