<h4>Insert Headers & Footers + Full WordPress Code Snippets Plugin</h4>
<a href="https://wpcode.com/?utm_source=wprepo&utm_medium=link&utm_campaign=liteplugin" rel="nofollow ugc">WPCode</a> (formerly known as Insert Headers and Footers by WPBeginner) is the most popular code snippets plugin for WordPress used by over 2 million websites.
We make it easy for you to add code snippets in WordPress without having to edit your theme’s functions.php file.
Our simple insert headers and footers interface allows you to insert code like Google Analytics, custom CSS, Facebook Pixel, and more to your WordPress site’s header and footer as well other areas of your website. No need to edit your theme files!
Aside from Header and Footer scripts, you can also use WPCode to insert custom PHP code snippets, JavaScript code snippets, CSS code snippets, HTML code snippets, and text snippets with full conditional logic support.
We took the pain out of adding custom code snippets in WordPress and made it easy.

Introducing New WPCode Pro 
 While WPCode Lite offers tons of powerful features for free, we listened to user feedback and created WPCode Pro with even more amazing features to improve your workflow. This includes smart conditional logic, saving code snippets to cloud library, code revisions, page-specific snippets, deeper integration with popular plugins like WooCommerce, Easy Digital Downloads, and so much more. <a href="https://wpcode.com/?utm_source=wprepo&utm_medium=link&utm_campaign=liteplugin" rel="nofollow ugc">Click here to purchase the best premium WordPress code snippet plugin now!</a>

<h4>Future Proof Code Snippet Management</h4>
Most <a href="https://www.wpbeginner.com/category/wp-tutorials/" rel="nofollow ugc">WordPress tutorial websites</a> ask you to add code snippets to your theme’s functions.php file. This makes managing code snippets messy, and it also prevents you from updating your theme.
If you ever update your theme or switch to another theme, then you will lose all custom code functions that you added in your functions.php file.
WPCode solves this by providing you an easy way to insert header and footer scripts along with other code snippets directly from your WordPress dashboard. These code snippets actually run as if they were in your theme’s functions.php file.
Our smart code snippet validation helps you prevent common code errors to ensure you never break your website when adding code snippets or header and footer scripts.
New WPCode Cloud Library even allows you to store all your custom code snippets in a cloud library, so you can easily re-use code snippets across multiple website projects and save time. You can keep your code snippets completely private or <a href="https://library.wpcode.com/?utm_source=wprepo&utm_medium=link&utm_campaign=liteplugin" rel="nofollow ugc">share it with the community</a> to give back while boosting your social profile.

This plugin allows me to not only add things to my site whenever needed, but it takes me only seconds to accomplish it.

<h4>Full Code Snippets Library and Code Generators</h4>
Ever wanted a central place to find all the most popular WordPress code snippets that are tested and proven to work?
When we started Insert Headers and Footers plugin, we did too. So we built a WordPress code snippets library right inside the WPCode plugin.
You will find verified PHP code snippets for popular feature requests like disable REST API, disable XML-RPC, disable comments, allow SVG file uploads, disable Gutenberg, add Classic Editor, and more without installing separate plugins for each.
<blockquote>
I was very hesitant to get into any of the code for my website. Your plugin made it easy for me to do. 
 Conbrio75 – WordPress user
</blockquote>
We also built the ability to save your code snippets to <a href="https://library.wpcode.com/?utm_source=wprepo&utm_medium=link&utm_campaign=liteplugin" rel="nofollow ugc">WPCode Cloud Library</a>, so you can easily re-use it on your other websites, client projects, or even share it with the larger community.
WPCode Cloud Library helps you better organize your code snippets in one central location, so you can save more time and speed up your workflow when managing websites. No more wasting time looking for custom notes or Github gists.
Aside from our growing code snippets library, we also have WordPress code generators to help you quickly get ready-to-use custom code using the latest WordPress coding standards and API’s.
<h4>Conditional Logic for Code Snippets + Code Insertion Priority</h4>
Our goal with WPCode was to create a WordPress code snippets plugin that’s both EASY and POWERFUL.
That’s why aside from our global header and footer scripts, we added advanced features like conditional logic for code snippets and made it easy.
Instead of learning WordPress conditional logic queries, you can use our beginner-friendly conditional logic user interface to:
<ul>
<li>Load code snippets for logged in users only</li>
<li>Load PHP code snippets for specific user roles</li>
<li>Load PHP code snippets only on specific page URLs</li>
<li>Insert header and footer pixel scripts on specific pages</li>
<li>Show code snippets based on type of page</li>
<li>Run code snippet only on certain post types</li>
<li>Load header and footer code snippet based on referrer source</li>
<li>and more…</li>
</ul>
We also added both automatic code insertion and manual code output using shortcodes.
Our Auto Insert feature allows you to run the code snippet everywhere or choose from custom options like:
<ul>
<li>Run code snippet only on frontend</li>
<li>Run code snippet only in WordPress admin area</li>
<li>Add header and footer scripts sitewide</li>
<li>Insert PHP code snippet before or after post content</li>
<li>Insert code snippet before or after specific paragraph</li>
<li>Insert code snippet on specific archive pages</li>
<li>Insert code snippets after specific WooCommerce function (<a href="https://wpcode.com/?utm_source=wprepo&utm_medium=link&utm_campaign=liteplugin" rel="nofollow ugc">Pro Feature</a>)</li>
</ul>
Aside from that, we also added a visual code snippet priority system, so you can choose the order for your custom functions to avoid code conflict.
<blockquote>
This is such a useful plugin! It makes it so much easier to include things on your website! 
 Understoryliving – WordPress user
</blockquote>
And for even more flexibility and customization, we have added the ability for you to add page-specific code snippets right from the WordPress classic editor as well as the Gutenberg editor. You can even load code snippets based on device type such as mobile only code snippets, desktop only code snippets, etc.
<h4>Import and Export Code Snippets</h4>
Managing multiple websites or developing in a staging environment?
We offer an easy way to import and export your custom code snippets, functions, and header and footer scripts to help you save time.
You can also save your code snippets to WPCode Cloud (Pro feature), so you can easily re-use the same code snippets across multiple websites. This also allows you to better organize your code snippets instead of wasting time searching for random Github gists.
<blockquote>
Simple plugin I use in quite every site. Very useful to insert scripts and tags.

WPCode – Insert Headers and Footers + Custom Code Snippets – WordPress Code Manager

I have been a user of Insert Headers and Footers for years, but the recent upgrade to WPCode is just amazing. Blows away the competition with conditional loading and everything.

Great additions

I was able to replace FIVE other plugins using snippets in this plugin. Made my day!

Fantastic Plugin

I've tried half a dozen or more of these code snippet manager plugins, and this one's my favorite because:

	it's from a reputable team
	their support on .org provides quick and thorough responses
	it has a very nice UI
	many of my ideal feature requests are already planned to be coming in the future
	I haven't experienced any bugs, including during import from an alternative plugin I migrated away from

The future features most important to me are cloud sync and easier creation of a custom shortcode.

I've tried them all and am happiest with this one

This was a great plugin when it did what it was initially intended for: to insert snippets of code in header and footer.
Now they decided to also allow you to add code snippets in the same plugin which is a risk factor and really error prone if the user doesn't know what he's doing.

Used to be a great plugin, not anymore

Using a huge space of the editor, to promote the PRO Version is not acceptable!!
I had to rollback to 2.0.3. 
Crazy marketing.


Had to Rollback to 2.0.3

Very nice guys... i use your plugins many years.. no problems at all.. 

Good Job !!!

Perfect Plugin !


I am using it for many years. It is reliable and it works with many codes that I need to use in headers.


The best solution for embeding codes


and good presets. The only downside is that the admin interface looks messy.


Great functions

Amazing

Best WP Code Plugin

Great plugin for custom css file, custom php code and javascript code. Makes site building much easier.


Combines Multiple Plugins


Disclaimer: I am an amateur programmer — not a professional one (in the sense that nobody pays me to do any programming). PHP is one of the programming languages that I'm reasonably familiar with; I'm not a complete stranger of the WordPress development environment, while not being a "power user" but merely a "tinkerer", even though I do have the odd plugin published here on the Plugin Library (they're all extremely simple).



Every now and then, I come across a very specific request from a customer, which is not covered by the theme/template/framework I've got to work with. Obviously, I can create my own plugin from scratch, or possibly clone the theme as a child theme, and add whatever is needed there. But this quickly gets out of hand: the "line of code needed on this page" suddenly becomes a whole block requiring parameters, then the same code needs to be placed elsewhere on the site as well, or perhaps turned into a widget on the sidebar, but then those parameters need a shortcode to make them easier to insert by the authors (who have no access to the PHP backend, of course), and so forth. How often have you come across that very issue? Well, in my case, I would say "almost on every project", with very few exceptions. Even by own personal blog has some hacking in it!



Enter WPCode. Even the free version allows you to do a ton of things without worrying about setting things up properly (i.e. creating a scaffolding for shortcodes, to give a good example) and the need to maintain them, tracking them "elsewhere". You simply edit your PHP code directly into the plugin and save it as a snippet. Then you call it from wherever you wish. There is nothing else to tweak, or change, or remember to do before moving to a different platform, etc. — you just make sure the plugin gets activated.



While the commercial version includes some nifty features such as full versioning and the ability to save those snippets remotely on the WPCode Library — where they can be reused across projects and/or even made public for others to use on their projects as well — the free version is not crippled in any form; it does what it promises, and does it well enough.



Kudos for the Dark Mode (ah, I yearn for having it across all of WordPress...) and the cool design of the (admin) interface. It's not 100% canonical regarding the WordPress "best practices", but as you all know, these are hopelessly outdated anyway. WPCode looks & feels good, it smells of professionalism, and has all sorts of cues and hints that you expect from something where you're going to edit code (no, it's not a simple adaptation of the "HTML" widget/Gutenberg block and its limited abilities...).



Allegedly, the commercial version throws in syntax checking on demand, as well as auto-complete for WordPress functions and several other bells and whistles, turning your WP admin panel in a full-fledged "WordPress Programming IDE", so to speak (or almost!). But I can imagine that in most scenarios, this won't be what people use it for, but rather to have the ability to grab one of the many snippets contributed to the WPCode Snipper Library and simply tweak them to do what you need. You can have much more than that, though — it even includes a "WP Query Generator", which provides a reasonably good scaffolding (strongly inspired on the official WordPress documentation!) to quickly create queries — even the most obscure ones! — using a menu and clicking on settings and forms. Then, after the query is generated (which happens instantly, in my experience), you can start to fiddle with it and adapt it to your specific needs. Made a mistake?... Oops, no problem, you can always go back, even on the free version (the paid one, as said, includes a full versioning system).



The ability to inject — safely! — arbitrary PHP code is the kind of thing that might be dangerous to do (exposing the WP innards to the web developer!), but it's also powerful, and much easier to do than manually editing files on disk. If you require that kind of thing — and, these days, who doesn't? — you will love WPCode, and wonder why nobody thought of this before?



(The short answer is: aye, there are alternative plugins to do the same thing; don't worry, WPCode will be able to import their data automatically as well :-) )


Even the free version is good beyond belief!


Powerfull and easy to use. A very useful plugin, definitely a must-have if you are a PHP programmer


Great piece of software!


A really well done snippets plugin that comes with a helpful collection of pre-made snippets. I was able to disable plugin auto-update emails without writing a line of code.


Brilliant Snippets Plugin!


I am a developer and use other snippet plugins, this one does not work for CSS, plain and simple.


CSS snippets do not work


works perfectly. can add conditions in free version.


great plugin


When working for customers using managed hosting, where we don't have access to the file system and can't or don't want to edit functions.php, or where an existing theme/page builder has no option for custom CSS and JavaScript, WPCode Snippets comes in very handy to edit the necessary custom code quickly without having to request additional permissions or credentials.


Very useful for managed instances

Excellent


Удобный и простой плагин. Его сделал гений.


Хороший плагин


I've found this plugin to be super useful in a range of situations. It's especially useful in prototyping code which can then be moved into PHP files in a theme or plugin.


Useful coding tool


Clean, logical, powerful interface for adding custom code.



The free version supports 90% of our needs.


The best there is

Easily add code snippets in WordPress. Insert header & footer scripts, add PHP code snippets with conditional logic, insert ads pixel code, and more.
