What PHP lacks is the ability to set the array pointer to an arbitrary key or value. There are ways to move forward and backward in the array but not a dedicated function to set the internal pointer to a specific key. Fortunately we can make it work, but it’s pretty archiac. We’ll need to loop through the array and look for what we want.

Timestamp Online is timestamp converver between unix timestamp and human readable form date. If you want to convert timestamp, it is sufficient to either enter your timestamp into input area, or you can construct URL with your timestamp – http://timestamp.online/timestamp/{your-timestamp}.
Timestamp Online also supports countdown, so you can see, how much time remains to particular timestamp. URLs for countdowns have following form – http://timestamp.online/countdown/{your-timestamp}.
Flask is an API of Python that allows us to build up web-applications. It was developed by Armin Ronacher. Flask’s framework is more explicit than Django’s framework and is also easier to learn because it has less base code to implement a simple web-Application. A Web-Application Framework or Web Framework is the collection of modules and libraries that helps the developer to write applications without writing the low-level codes such as protocols, thread management, etc. Flask is based on WSGI(Web Server Gateway Interface) toolkit and Jinja2 template engine.
WordPress plugin developers are adopting AI-powered tech and building it into their products, such as RankMath’s AI-generated suggestions for creating SEO-friendly content, WordPress.com’s experimental blocks for AI-generated images and content, and a Setary’s plugin that uses AI to write and bulk edit WooCommerce product descriptions. The wpfrontpage site is tracking these plugins but WordPress.org also lists dozens of plugins with AI, many of them created to write content or generate images.
To understand what Flask is you have to understand a few general terms.
WSGI Web Server Gateway Interface (WSGI) has been adopted as a standard for Python web application development. WSGI is a specification for a universal interface between the web server and the web applications.
Werkzeug It is a WSGI toolkit, which implements requests, response objects, and other utility functions. This enables building a web framework on top of it. The Flask framework uses Werkzeug as one of its bases.
jinja2 jinja2 is a popular templating engine for Python. A web templating system combines a template with a certain data source to render dynamic web pages.
Flask is a web application framework written in Python. Flask is based on the Werkzeug WSGI toolkit and Jinja2 template engine. Both are Pocco projects.
The Flexbox Method
.scrolling-wrapper-flexbox {
display: flex;
flex-wrap: nowrap;
overflow-x: auto;
.card {
flex: 0 0 auto;
}
}
Although the plugin is free, getting access to OpenAI’s server is not. It’s very reasonably priced – most basic questions and answers will cost a fraction of a cent – but if you’ve got a heavily trafficked site or visitors making excessive use of the chatbot, costs can quickly ramp up.
In an attempt to make your WordPress search even more user friendly, you can highlight the search terms in the results. We did this for one of our clients, so we thought it would be useful for other users. In this article we will show you how you can highlight search terms in the results in WordPress.
I came across this use-case where we had to use a specific custom font but it was only available in .otf. However, we want to support multiple formats to ensure even deprecated browsers can load the font. Otf has a global coverage of 97.89% but we didn’t want to take any chances of the font not loading as it’s a crucial feature in our app.
I wanted to convert the font to support the following browsers:
GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.
A headless Content Management System, or headless CMS, is a back end-only web content management system that acts primarily as a content repository. A headless CMS makes content accessible via an API for display on any device, without a built-in front end or presentation layer. The term ‘headless’ comes from the concept of chopping the ‘head’ (the front end) off the ‘body’ (the back end).
Just add controlsList="nodownload" in your video tag.
The importance of wp_localize_script is when you can pass data directly from PHP to JavaScript.
Functions is very easy to handle there are only 3 parameters required :
$handle
(string) (Required) Script handle the data will be attached to.
$object_name
(string) (Required) Name for the JavaScript object. Passed directly, so it should be qualified JS variable. Example: ‘/[a-zA-Z0-9_]+/’.
$l10n
(array) (Required) The data itself. The data can be either a single or multi-dimensional array.
You can use single_template filter hook.
function load_movie_template( $template ) {
global $post;
if ( 'movie' === $post->post_type && locate_template( array( 'single-movie.php' ) ) !== $template ) {
/*
* This is a 'movie' post
* AND a 'single movie template' is not found on
* theme or child theme directories, so load it
* from our plugin directory.
*/
return plugin_dir_path( __FILE__ ) . 'single-movie.php';
}
return $template;
}
add_filter( 'single_template', 'load_movie_template' );
There are a few steps to create the custom quick edit box and custom column
This tutorial is meant for D3 v5-v7.
This tutorial is a quick intro to D3.js, a Javascript library for creating interactive data visualizations in the browser. D3 is built on top of common web standards like HTML, CSS, and SVG.
This is not designed to be a deep dive — this tutorial will teach you how to learn D3 and give you a high-level understanding of this powerful tool.
a fork on the classic original because I found the straigth arrows to be more pleasant (especially if using a single color) by changing linkArc() and increasing the arrow length by a little using forceCollide(). I also increased the radius and the text positioning.
Broadly speaking there are 4 steps to setting up a force simulation:
forceSimulation, passing in the array of objectsforceManyBody, forceCenter, forceCollide) to the systemI’ve just had a nice experience improving and modernizing a large JavaScript codebase in a WordPress plugin. The original code was written in an old-fashioned way with jQuery in a single large file. Using modern EcmaScript and tools like Webpack, I was able to split it into modules and improve the code structure. The new code is much more readable and maintainable, and of course, fewer bugs. In this tutorial, I’ll show you how I did that.
ECMAScript 2015 or ES2015 is a significant update to the JavaScript programming language. It is the first major update to the language since ES5 which was standardized in 2009. Therefore, ES2015 is often called ES6.
cola.js (A.K.A. «WebCoLa») is an open-source JavaScript library for arranging your HTML5 documents and diagrams using constraint-based optimization techniques.
It works well with libraries like D3.js, svg.js, and Cytoscape.js. The core layout is based on a complete rewrite in Javascript of the C++ libcola library.
It also has an adaptor for d3.js that allows you to use cola as a drop-in replacement for the D3 force layout. The layout converges to a local optimum unlike the D3 force layout, which forces convergence through a simple annealing strategy. Thus, compared to D3 force layout:
WebM video format. Multimedia format designed to provide a royalty-free, high-quality open video compression format for use with HTML5 video. WebM supports the video codec VP8 and VP9.
Global 79.04% + 18.82% = 97.86%
Basic check is simple, wait for the ended event. This is so simple you can just google it.
Now to check that user played full video an extensive analysis would be needed checking if he played every second of it. That’s not necessary however, it should be enough that user:
This snippet demonstrates exactly that. The video will not be marked as fully played if you just skip to the end. Playing the beginning over and over will also not mark it fully played
In light of a recent German court case, which fined a website owner for violating the GDPR by using Google-hosted webfonts, WordPress.org’s themes team is updating its recommendations for hosting webfonts. Most theme authors have been enqueuing Google Fonts from the Google CDN for better performance, but this method exposes visitors’ IP addresses.
“The themes team strongly encourages the theme authors to update their themes,” Themes Team representative @benachi said in a recent announcement. “We recommend updating by switching to locally hosted webfonts. Luckily Google Fonts can be downloaded and bundled in a theme. Bundled font files allow users to host webfonts locally and comply with GDPR.”
Why bother with a random green when you can choose to be a #BADA55!
Just add your desired image size (width & height) after the service URL, and you’ll get a random image:
https://picsum.photos/200/300
The autocomplete is generated with help from jQuery UI Autocomplete, a script that is included in WordPress as default.
Enable HTTP/2 module
Apache’s HTTP/2 support comes from the mod_http2 module. Enable it from:
a2enmod http2
apachectl restart
If above commands do not work in your system (which is likely the case in CentOS/RHEL), use LoadModule directive in httpd configuration directory to enable http2 module.
Add HTTP/2 Support
We highly recommend you enable HTTPS support for your web site first. Most web browser simply do not support HTTP/2 over plain text. Besides, there are no excuses to not use HTTPS anymore. HTTP/2 can be enabled site-by-site basis. Locate your web site’s Apache virtual host configuration file, and add the following right after the opening
Protocols h2 http/1.1
It turns out this was the easy part. All you need to do is symlink your VVV directory to whatever syncing program you happen to be using (Dropbox, Google Drive, etc.). You can also move your entire VVV directory into Dropbox, but I prefer a symlink to keep the separation.
…decenas de revistas, cuentos, webs y aplicaciones comerciales con una estética similar a la de la ilustración que decora este artículo. A ese estilo se le conoce como «Alegria» o «Corporate Memphis». Es un producto de la precarización y la devaluación del trabajo y tiene decenas de variantes y versiones, todas igualmente exánimes y repetitivas.
El resultado es un cambio cualitativo. Cualquiera puede hacer una ilustración dentro de los códigos visuales del «Corporate Memphis». Ya no es solo que el ilustrador -uno de los últimos artesanos- se haya proletarizado, ni siquiera que una vez proletarizado haya sido expulsado de la oficina y se haya precarizado al extremo vendiendo horas de trabajo en una plataforma. Ahora el ilustrador como tal es ya innecesario.
La automatización combinatoria de un código estándar de imágenes pre-diseñadas permitirá que ilustrar se convierta en una tarea más del desarrollador web. Una entre otras muchas que ya se han automatizado o están en camino de hacerlo. Porque el desarrollador es el primero que ha sufrido la estandarización y procedimentación automatizada de su trabajo. Ahora, Inteligencia Artificial mediante, está siendo alienado incluso de la algoritmia.
Web scraper is a technique for extracting structured information from a web page. With Python, you can build a efficient web scraper by using BeautifulSoup, requests and other libraries. However, these solution is not fast enough. In this article, I will show you some tips to build a super fast web scraper with Python.
Use the –user=
You can use the $options array to set the samesite value, for example:
setcookie($name, $value, [
‘expires’ => time() + 86400,
‘path’ => ‘/’,
‘domain’ => ‘domain.com’,
‘secure’ => true,
‘httponly’ => true,
‘samesite’ => ‘None’,
]);
The value of the samesite element should be either None, Lax or Strict.
So how do you set cookies in WordPress? With core constants:
COOKIEPATH — Server path in which the cookie will be available on.
COOKIE_DOMAIN — The (sub)domain that the cookie is available to.
Setting cookies in WordPress, especially the expiration is a cinch using one of the core time constants, available since v3.5:
MINUTE_IN_SECONDS = 60 seconds
HOUR_IN_SECONDS = 3,600 seconds
DAY_IN_SECONDS = 86,400 seconds
WEEK_IN_SECONDS = 604,800 seconds
MONTH_IN_SECONDS = 2,629,746 seconds
YEAR_IN_SECONDS = 31,556,952 seconds
Don’t forget to add the current timestamp to one of these constants, for example:
// 5 minutes into the future
$five_minutes = current_time( ‘timestamp’ ) + ( MINUTE_IN_SECONDS * 5 );
In the first parts we focus on the basics. We set up a development environment with running compilation of our code. And the basics of how to register a block and the necessary PHP parts of it as well. We’ll learn about the huge library of components and methods available to us from WordPress Gutenberg.
Moving on we’ll learn about how to add sections and settings for our block in the editor sidebar (Inspector) as well as customizing the toolbar. Along the way we’ll touch a lot of different input types and how to use Gutenberg’s component for these. And of course we’ll learn how to save, update and output the saved information to our block – and how that works behind the scenes.
At the end we’ll look at more advanced things like dynamic blocks and how to use PHP to render the block output. And finally how to make post queries inside the editor – allowing the user to select a post from a list for render.
