Ensuring WCAG Compliance in Apache-served Applications with Dynamic Content
I've been banging my head against this for hours. I'm performance testing and I've been working on this all day and I'm working on a project and hit a roadblock. While designing a web application that aims to be fully accessible, I’m focusing on ensuring compliance with WCAG standards, particularly when it comes to dynamically served content via Apache. Recently, I set up Apache 2.4.54 with mod_rewrite and PHP to handle our content, but I'm not entirely confident that I'm implementing best practices for accessibility. I’ve already configured my `.htaccess` file to include the following rules for clean URLs: ```apache RewriteEngine On RewriteRule ^content/(.*)$ content.php?item=$1 [L,QSA] ``` This is working well for SEO, but I’m concerned about how accessible this content is, especially for screen readers. Specifically, I’m not sure how to ensure that the HTML being served dynamically retains all necessary ARIA attributes for assistive technologies. I’ve been reading through the [WCAG guidelines](https://www.w3.org/WAI/WCAG21/quickref/) and understand the importance of providing alternative text for non-text content. My dynamic PHP code includes a function to output images: ```php function renderImage($src, $alt) { echo '<img src="' . htmlspecialchars($src) . '" alt="' . htmlspecialchars($alt) . '">'; } ``` This seems straightforward, but I wonder if there's anything specific I should be doing to handle images that may change based on user input or content updates. Additionally, I'm trying to implement ARIA roles on my navigation elements where users can filter content. Here’s a snippet of my navigation structure: ```html <nav aria-label="Main Navigation"> <ul> <li><a href="#" role="button">Filter 1</a></li> <li><a href="#" role="button">Filter 2</a></li> </ul> </nav> ``` Could this approach inadvertently confuse screen readers? I’m also considering how to provide contextual help or instructions as content loads dynamically. Any advice on how to improve accessibility in this context, particularly regarding server-side rendering and client-side updates, would be greatly appreciated. Is there a recommended approach for managing ARIA states in a context like this? Looking forward to the community's insights on best practices for combining Apache configurations with accessibility standards in dynamically served applications. I'm working on a API that needs to handle this. Am I missing something obvious? This is my first time working with Php LTS. Could this be a known issue? I'm developing on Ubuntu 20.04 with Php. Thanks for any help you can provide!
