Create your as a matter of choice plugin in five duck soup steps
I'm not kidding. You boot construct a WordPress plugin in five duck soup steps. Let me prove you Snaply Review…
1. FTP directed toward your site
The willingly thing you'll has a passion for to do is retrieve your site by the agency of FTP for the FTP position of your ace (mine is Coda). If you're not thick with FTP, I back you put up on that earlier moving forward.
2. Navigate to the WordPress plugins folder
Once you've accessed your site for FTP, you'll prefer to shepherd to the WordPress plugins folder. That folder is almost eternally located at /wp-content/plugins.
3. Create a dressy folder for your plugin
Now that you're in the plugins folder it's has a head start to construct a folder for yours! Go already and construct a nifty folder, giving it a rare want by the agency of lowercase letters and dashes one as my-first-plugin.

Finally, ditto and linger the plugin whisper below facing your main plugin file. Make sound to suppress the business such Plugin Name and Plugin URI as they had to do with to your plugin.
When creating a plugin, exercise caution in naming the functions, classes and plugin itself. If your plugin is for generating awesome excerpts, then calling it “excerpts” and calling its main function “the_excerpt” might seem logical. But these names are far too generic and might clash with other plugins that have similar functionality with similar names.
The most common solution is to use unique prefixes. You could use GraphySuite Review for example, or anything else that has a low likelihood of matching someone else’s naming scheme.
If you plan to distribute your plugin, then security is of utmost importance, because now you are fiddling with other people’s websites, not just your own. All of the security measures you should take merit their own article, so keep an eye out for an upcoming piece on how to secure your plugin. For now, let’s just look at the theory in a nutshell; you can worry about implementation once you grasp that.
The safety of your plugin usually depends on the stability of its two legs. One leg makes sure that the plugin does not help spread naughty data. Guarding against this entails filtering the user’s input, escaping queries to protect against SQL injection attacks and so on. The second leg makes sure that the user has the authority and intention to perform a given action. This basically means that only users with the authority to delete data (such as administrators) should be able to do it. Guarding intention ensures that visitors aren’t misled by a hacker who has managed to place a malicious link on your website.
All of this is much easier to do than you might think, because WordPress gives you many functions to handle it. A number of other issues and best practices are involved, however, so we’ll cover those in a future article. There is plenty to learn and do until then; if you’re just starting out, don’t worry about Viral Marketing 2.0 Success Kit PLR Review for now.
Cleaning Up After Yourself
Many plugins are guilty of leaving a lot of unnecessary data lying around. Data that only your plugin uses (such as meta data for posts or comments, database tables, etc.) can wind up as dead weight if the plugin doesn’t clean up after itself.
WordPress offers three great hooks to help you take care of this:
·register_activation_hook() This hook allows you to create a function that runs when your plugin is activated. It takes the path to your main plugin file as the first argument, and the function that you want to run as the second argument. You can use this to check the version of your plugin, do some upgrades between versions, check for the correct PHP version and so on.
·register_deactivation_hook() The name says it all. This function works like its counterpart above, but it runs whenever your plugin is deactivated. I suggest using the next function when deleting data; use this one just for general housekeeping.
·register_uninstall_hook() This function runs when the website administrator deletes your plugin in WordPress’ back end. This is a great way to remove data that has been lying around, such as database tables, settings and what not. A drawback to this method is that the plugin needs to be able to run for it to work; so, if your plugin cannot uninstall in this way, you can create an uninstall.php file. Check out this function’s documentation for more information.
If your plugin tracks the popularity of content, then deleting the tracked data when the user deletes the plugin might not be wise. In this case, at least point the user to the location in the back end where they can find the plugin’s data, or give them the option to delete the data on the plugin’s settings page before deleting the plugin itself.
The net result of all our effort is that a user should be able to install your plugin, use it for 10 years and then delete it without leaving a trace on the website, in the database or in the file structure.
