It’s about building a smart system where text size, spacing, and layout adjust on their own for different screen sizes, so you don’t have to keep rewriting styles again and again. I am explaining everything in simple way. It covers the right media query ranges to use, how to make text sizes adjust smoothly on different screens, and how to set global CSS styles that automatically scale across devices.https://sanjaybhowmick.github.io/posts/resources---managing-multiple-project-versions-in-the-same-github-repository/https://sanjaybhowmick.github.io/posts/resources---managing-multiple-project-versions-in-the-same-github-repository/Fri, 17 Apr 2026 00:00:00 UTCI have been working on a project for years, and suddenly I have to create a completely different version of the same codebase. In my case, I have: Version 1 → Already in Git (Folder 1), synced with main branch Version 2 → New code (Folder 2), no Git setup Now, my goal is Move existing code (Version 1) → version1 branch Upload new code (Version 2) → main branchhttps://sanjaybhowmick.github.io/posts/html---form-validation/https://sanjaybhowmick.github.io/posts/html---form-validation/Fri, 10 Apr 2026 00:00:00 UTCWhen I build a contact form or a complex application, I ensure that users enter the correct data that helps data accuracy and proper user experience. In this article I am sharing a complete collection of commonly used HTML form validation patterns, attributes, and examples. 1.

I notice that AI generates content using the same common pattern, and anyone can identify it as AI-generated content. AI-generated content may not be good for search engines while indexing the websites. I tried different types of prompts, and finally these prompts are generating quite impressive content that seems to be human-written. New Content Write fresh and original content on the given topic. Use very simple Indian English. Write short and clear sentences. Avoid complex words and long sentences. The content should sound natural and human-written. Make it easy to understand for a 4th or 5th standard Indian student. Keep the tone friendly and positive. Do not use technical or difficult language.https://sanjaybhowmick.github.io/posts/wordpress---dynamic-html-sitemap/https://sanjaybhowmick.github.io/posts/wordpress---dynamic-html-sitemap/Fri, 18 Jul 2025 00:00:00 UTCAn HTML sitemap is a simple way to display all your website’s content in one place.

You can overwrite this by adding this small piece of code in the functions.php file of your theme. function custom_wp_mail_from_name($email_from_name) { return 'Your Website Name'; // Change this to your desired name } add_filter('wp_mail_from_name', 'custom_wp_mail_from_name'); Also you can change the default from email id of the email generated from WordPress website by adding this another function in the functions.php file of your theme. function custom_wp_mail_from($email) { return 'no-reply@yourdomain.com'; // Change this to your desired email } add_filter('wp_mail_from', 'custom_wp_mail_from');https://sanjaybhowmick.github.io/posts/wordpress---export-mysql-table-data-to-csv/https://sanjaybhowmick.github.io/posts/wordpress---export-mysql-table-data-to-csv/Thu, 03 Apr 2025 00:00:00 UTCTo create a custom menu page in WordPress, retrieve custom table data from MySQL, and display it with the ability to export to CSV/Excel, you can follow these steps: Step 1: Create a custom table in your WordPress database to store your data. You can use the $wpdb global variable to interact with custom tables in WordPress. Here’s an example of creating a custom table: <?php global $wpdb; $table_name = $wpdb->prefix . 'custom_data'; $sql = "CREATE TABLE IF NOT EXISTS $table_name ( id INT(11) NOT NULL AUTO_INCREMENT, name VARCHAR(255) NOT NULL, email VARCHAR(255) NOT NULL, phone VARCHAR(20) NOT NULL, PRIMARY KEY (id) ) $charset_collate;"; require_once(ABSPATH . 'wp-admin/includes/upgrade.php'); dbDelta($sql); ?> Step 2: Add the following code to your theme’s functions.php file or create a custom plugin file to define the custom menu page:https://sanjaybhowmick.github.io/posts/php---download-file-from-specific-folder/https://sanjaybhowmick.github.io/posts/php---download-file-from-specific-folder/Tue, 11 Mar 2025 00:00:00 UTCBelow is a simple example of a PHP script that allows you to download file from a specific folder. You can link to this PHP file with the file name as a parameter. Create a file named download.php and add the following code: <?php // Specify the folder where your files are stored $folderPath = '/path/to/your/files/'; // Get the file name from the query parameter if (isset($_GET['file'])) { $fileName = basename($_GET['file']); $filePath = $folderPath . $fileName; // Check if the file exists if (file_exists($filePath)) { // Set headers for download header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename="' . $fileName . '"'); header('Expires: 0'); header('Cache-Control: must-revalidate'); header('Pragma: public'); header('Content-Length: ' . filesize($filePath)); // Read the file and output it to the browser readfile($filePath); exit; } else { echo 'File not found.'; } } else { echo 'File parameter missing.'; } ?> Replace ‘/path/to/your/files/’ with the actual path to the folder where your files are stored. Now, you can link to this script by providing the file name as a parameter, like this:https://sanjaybhowmick.github.io/posts/wordpress---elementor-cache-update/https://sanjaybhowmick.github.io/posts/wordpress---elementor-cache-update/Tue, 11 Feb 2025 00:00:00 UTCWhen you move your WordPress site to a new domain, some design problems can happen. This is common if you use Elementor. Your website may look broken. Some styles may not load. The layout may look different. This happens because Elementor saves design data and links with the old domain. After moving the site, these do not update on their own. In this guide, you will learn simple steps to fix this. You will update links, refresh styles, and make your website look normal again.https://sanjaybhowmick.github.io/posts/php---upload-image-and-pdf-file/https://sanjaybhowmick.github.io/posts/php---upload-image-and-pdf-file/Mon, 10 Feb 2025 00:00:00 UTCHere is a PHP script that allows users to upload image and PDF files with a maximum size of 5 MB. The uploaded files will be renamed using the current timestamp: <?php if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_FILES["file"])) { $allowedExtensions = array("jpg", "jpeg", "png", "pdf"); $maxFileSize = 5 * 1024 * 1024; // 5 MB in bytes $targetDirectory = "uploads/"; $timestamp = time(); $targetFileName = $timestamp . "_" . basename($_FILES["file"]["name"]); $targetPath = $targetDirectory . $targetFileName; $fileExtension = strtolower(pathinfo($targetFileName, PATHINFO_EXTENSION)); if (in_array($fileExtension, $allowedExtensions) && $_FILES["file"]["size"] <= $maxFileSize) { if (move_uploaded_file($_FILES["file"]["tmp_name"], $targetPath)) { echo "File uploaded successfully."; } else { echo "Error uploading file."; } } else { echo "Invalid file. Allowed file types: jpg, jpeg, png, pdf. Max file size: 5 MB."; } } ?> This is HTML form for file upload.
