🔹 How to trigger a click event inside an iframe
This article explains how to trigger a button click inside an iframe from an external script. It highlights that modifying an iframe is possible when it comes from the same domain. The article includes HTML and JavaScript examples that show how to use the contentWindow property to access the iframe content and trigger a click event on a specific element. It also demonstrates how to modify iframe content, add CSS styles to hide elements or change the background, and use the onload event to introduce persistent changes after the iframe loads. The article emphasizes that interacting with iframe content is possible using custom JavaScript in the main document.
🔹 Slow Docker on Windows WSL2 – How to Improve Performance
This article focuses on solving Docker performance issues on Windows. These problems often result from incorrect configuration, causing Docker to run slowly. The solution is to run Docker with Ubuntu 20.04 LTS and WSL2 enabled. The article provides step-by-step instructions for enabling WSL2 on Windows, installing Ubuntu, configuring SSH, setting up PHPStorm, running Docker, and connecting to a database. Switching to WSL2 allows Linux containers to run natively without emulation, significantly improving performance—browser requests execute in less than 1 second instead of 60 seconds. This solution works for frameworks like PHP Symfony, React Node server, and Ruby on Rails. The article also includes a troubleshooting section addressing common errors users may encounter during implementation.
🔹 Windows Fix for Warning: PHP Startup – Unable to Load Dynamic Library
This article explains how to fix PHP startup warnings on Windows, which often appear when using WP CLI and PHP Composer. These warnings can be frustrating as they interfere with command execution. The article explains that the cause is usually a missing PHP extension or an issue with loading it. The solution is to locate the php.ini file using the php –ini command and change the display_startup_errors setting from On to Off. Disabling display_startup_errors ensures that warnings are no longer displayed, allowing WP CLI commands to run normally. The article also provides an example of exporting a WordPress database using WP CLI after modifying the php.ini file.
🔹 i18next & React – Links Inside Translations
This article explains how to add dynamic translations for links in React using the i18next library. It highlights the challenge of translating phrases containing variables (such as URLs) and suggests that hardcoding URLs in each translation file is not optimal. The article presents a solution using the Trans and LinkText components from react-i18next. LinkText creates an <a href=”…”> link, while Trans allows embedding React components inside translations. This way, dynamic variables can be passed into translated text, making the code cleaner and more readable. A practical example demonstrates how to translate a privacy policy text containing two links using this method. The article also explains how to install react-i18next, configure i18n, add a JSON translation file, and implement the RegisterForm and LinkText components to display translated text with links.
🔹 iFrame – How to Access Camera Cross-Domain
This article explains how to access a camera and microphone inside an iframe when the iframe is hosted on a different domain. By default, access to media devices is blocked due to security restrictions. The article suggests a solution using the allow attribute in the <iframe> tag. By adding allow=”autoplay; camera; microphone”, the iframe is granted access to the camera and microphone. The article also demonstrates how to dynamically add this attribute using JavaScript and refresh iframe permissions by modifying the iframe URL (adding a query string parameter), which resets MediaRecorder API permissions. Additionally, the article presents a simple React application embedded in an iframe that uses MediaRecorder to record audio and video. The source code for the React app, including the RecordView component for recording and displaying video previews, is also provided. Furthermore, it includes an example HTML test page with an iframe and a button that dynamically adds the allow attribute and refreshes permissions. In summary, the article offers a practical solution for cross-domain iframe camera access, with code examples and step-by-step instructions for implementation.
