The WordPress plug-in is the perfect tool to enhance the functionality of your website. But sometimes they can’t do what you want correctly. So. It is very common for developers to customize and extend plug-ins as needed. This paper introduces several methods of customizing plug-ins on the website. You cannot be 100% sure that you will modify the plug-in after selecting the correct plug-in to customize and installing it. However, if you consider extending functions, it is recommended to select the correct plug-in. Note: good plug-ins are actively maintained by the author. User base related to niche market. Bug fixes and active support records. Provide the required functions and functions. This is not the only requirement. If the plug-in has a hook library, it can expand the function more easily, which will be an advantage.
Why customization? WordPress plug-ins are software that adds functionality to websites. Usually, plug-ins will appeal to various platforms and most word press themes, but their functions may still not meet specific requirements. Therefore, you can always switch to customizing and extending the functionality of specific software. WordPress plug-ins are flexible and easy to modify. By customizing, you can save time and continue to use your favorite software without having to build your own solution from scratch. Use the core functions of third-party plug-ins and extend them as needed.
The easiest way to apply certain changes to plug-in developers and collaborative plug-in output is to consult the plug-in creator. The largest WordPress plug-in directory is WordPress. org。 All developers share contact information there. Some of them are open to ideas, proposals and collaboration. If you are interested in collaboration, you can send a patch with suggested changes. If this is what they are considering adding, you can look forward to making changes in the next update or getting help before. The following way to customize a hook is to use a hook. What are they?
A hook provides a piece of code that can interact and modify with other pieces of code in a specific location. Hooking is the basis of how plug-ins interact with WordPress core. There are two types of hooking: task and filter. To use one of these, you must create a callback, which is a user-defined function. Then, register a specific filter or action in the WordPress hook. What is the difference between tasks and filters? Actions can add data or change how word press works. The callback function of actions runs when word press is running, and some actions can be performed. The task does not return any call hooks.
Filters allow you to change data while running WordPress. The callback function of the filter accepts, modifies, and returns variables. They work independently and have no effect on global variables and outputs. In short, the main differences between action and hooking are: The action receives the received information and performs the operation without returning any call hook. The filter will get, modify and return the received information. That is, filter something out and then transfer it back to the hook for later use. WordPress has many hooks. If the plug-in you are using contains a custom hook, you can expand it. In addition, you can shape yourself.
Let’s look at an example of using a custom hook. \
The ocommerce_after_cart_totals operation makes it easy to add content under the total area of the shopping cart. Use the fontawesome icon to display the credit card logo. Text indicating available credit cards can be added below the logo. You can customize the appearance of the content. These simple tasks are useful when you need to add content to a specific location.
Some developers do not include custom hooks in their plug-ins. In this case, you can redefine callbacks or add custom hooks. Simply enter the custom hook changes directly into the plug-in and add the required custom hook. Then, you must put the rest of the functionality into a separate plug-in. Next, you need to contact the developer and ask them to submit the patch, including the custom hook required for the next update. With luck, you can upgrade your plug-ins and interact seamlessly with them. If they refuse, they can also manually patch the custom hook to each new release and upgrade it.
Another way to redefine callback WordPress plug-in functionality is to redefine callbacks. This method helps to change the way the plug-in interacts with the platform. When adding a custom callback, create the function you want to view in the plug-in. The plug-in will register the callback function of the core hook and integrate with WordPress. You can remove the callback and replace it with your own. The functions of other plug-ins must be called in the callback to recreate the required functions. It is recommended that mature developers use this option. Changing the plug-in output changing the plug-in default output may be the best choice.
When the plug-in is irrelevant to your site, the terminology used by the plug-in may not be consistent with the website. For example, woocommerce’s term \
In the example of changing data or adding woocommerce under special circumstances, we can try another method of adding or changing data for special circumstances. For example, some information must be displayed on all products in a particular category. Add global changes to avoid manually adding this information to each product. What should I do? The is_product() woocomerce function and has_term() WordPress function are combined for specific categories of products, so you can add important information. <? php
When customizing WordPress plug-ins, it is sometimes difficult to change the functions of plug-ins that should not be done, and errors may occur. Common problems include failing to back up the website before the process starts or changing the plug-in code without saving the original code to another location. Fortunately, most mistakes can be avoided. First, you must always save the source code of the plug-in in case it needs to be loaded. Also, always save a copy of the changes you made to the plug-in while retaining the original code. Therefore, even if there is a problem, you can be sure that the task has been saved. In addition, the dump environment should be used when customizing or manually writing WordPress plug-ins.
Good. This will not damage the functionality of the real-time website. Plug ins are a great tool for creating WordPress websites perfectly. Unfortunately, you may encounter some limitations. However, these restrictions can be easily modified through customization. All of the above methods are suitable for inexperienced developers. Extend the functionality of the plug-in to improve the website.
