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'); /posts/wordpress---export-mysql-table-data-to-csv/ /posts/wordpress---export-mysql-table-data-to-csv/ Thu, 03 Apr 2025 00:00:00 UTC To 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: /posts/php---download-file-from-specific-folder/ /posts/php---download-file-from-specific-folder/ Tue, 11 Mar 2025 00:00:00 UTC Below 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($filePath); exit; } else { echo 'File not found.'; } } else { echo 'File parameter missing.'; } ?> Replace ‘/path/to/your/files/’ with the actual path to the folder where your files are stored. Now, you can link to this script by providing the file name as a parameter, like this: /posts/php---upload-image-and-pdf-file/ /posts/php---upload-image-and-pdf-file/ Mon, 10 Feb 2025 00:00:00 UTC Here is a PHP script that allows users to upload image and PDF files with a maximum size of 5 MB. The uploaded files will be renamed using the current timestamp: <?php if ($_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. /posts/php---get-mysql-columns-total-and-show-highest-totals/ /posts/php---get-mysql-columns-total-and-show-highest-totals/ Fri, 10 Jan 2025 00:00:00 UTC To get the total of a MySQL field and then select the three highest totals from the table, you can use the following PHP script: <?php // Assuming you have already established a MySQL connection // Retrieve the total of a field and select the three highest totals $servername = "localhost"; $username = "your_username"; $password = "your_password"; $dbname = "your_database_name"; // Create a new MySQL connection $conn = new mysqli($servername, $username, $password, $dbname); // Check the connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } // Prepare and execute the SQL statement to get the total and select three highest totals $sql = "SELECT SUM(field_name) AS total FROM table_name GROUP BY field_name ORDER BY total DESC LIMIT 3"; $result = $conn->query($sql); if ($result && $result->num_rows > 0) { echo "Three highest totals: <br>"; while ($row = $result->fetch_assoc()) { $total = $row['total']; echo $total . "<br>"; } } else { echo "No records found."; } // Close the database connection $conn->close(); ?> Make sure to replace ‘your_username’, ‘your_password’, ‘your_database_name’, ‘field_name’, and ‘table_name’ with the actual values for your MySQL configuration and table structure. /posts/html---comparision-of-changed-data-in-table-rows/ /posts/html---comparision-of-changed-data-in-table-rows/ Wed, 11 Dec 2024 00:00:00 UTC In a HTML table where have multiple rows of same data with some difference in any cell. Now you want to highlight that specific cell data which is changed only. We can achieve this using JavaScript. Here’s a basic example of how you could implement this functionality: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Highlight Changed Data</title> <style> .changed { background-color: yellow; } </style> </head> <body> <table id="data-table"> <thead> <tr> <th>Column 1</th> <th>Column 2</th> <th>Column 3</th> </tr> </thead> <tbody> <tr> <td>Initial Value 1</td> <td>Initial Value 2</td> <td>Initial Value 3</td> </tr> <tr> <td>Changed Value 1</td> <td>Changed Value 2</td> <td>Changed Value 3</td> </tr> <!-- Add more rows as needed --> </tbody> </table> <script> window.onload = function () { const table = document.getElementById('data-table'); const rows = table.getElementsByTagName('tr'); for (let i = rows.length - 1; i > 0; i--) { const currentRow = rows[i]; const previousRow = rows[i - 1]; if (!previousRow) { break; // Exit loop if no previous row (first row) } const currentCells = currentRow.getElementsByTagName('td'); const previousCells = previousRow.getElementsByTagName('td'); for (let j = 0; j < currentCells.length; j++) { const currentCell = currentCells[j]; const previousCell = previousCells[j]; if (currentCell.textContent !== previousCell.textContent) { currentCell.classList.add('changed'); } } } }; </script> </body> </html> This code compares each cell of each row with the corresponding cell of the previous row. If the content of a cell is different from the content of the corresponding cell in the previous row, it adds a changed class to highlight the change. Note: You can customise the appearance of the changed cells by modifying the CSS class .changed. /posts/php---export-mysql-data-to-csv/ /posts/php---export-mysql-data-to-csv/ Mon, 25 Nov 2024 00:00:00 UTC To fetch data from a MySQL database and export it to CSV using PHP, you can follow these steps: <?php // Database connection details $servername = "localhost"; $username = "your_username"; $password = "your_password"; $dbname = "your_database_name"; // Create connection $conn = new mysqli($servername, $username, $password, $dbname); // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } // Fetch data from your table $sql = "SELECT * FROM your_table"; $result = $conn->query($sql); // Check if any rows are returned if ($result->num_rows > 0) { // Define CSV filename $filename = "exported_data.csv"; // Set headers for CSV download header('Content-Type: text/csv'); header('Content-Disposition: attachment; filename="' . $filename . '"'); // Create a file pointer connected to the output stream $output = fopen('php://output', 'w'); // Output CSV header $header = array('ID', 'Name', 'Email'); fputcsv($output, $header); // Output data from rows while ($row = $result->fetch_assoc()) { fputcsv($output, $row); } // Close the file pointer fclose($output); } else { echo "No data found"; } // Close the database connection $conn->close(); ?> Explanation: /posts/php---import-csv-data-into-mysql/ /posts/php---import-csv-data-into-mysql/ Thu, 21 Nov 2024 00:00:00 UTC Here’s a detailed example of how to import data from a CSV file into a MySQL database using PHP. The script processes each row one by one, displays a success message for each successfully inserted row, and stops the process if any error occurs, showing the error message. Prerequisites: Ensure you have a MySQL database and table set up to store the CSV data. Adjust the database connection details and table schema as needed. /posts/php---print-total-of-a-variable-inside-while-loop-outside-of-the-loop/ /posts/php---print-total-of-a-variable-inside-while-loop-outside-of-the-loop/ Thu, 21 Nov 2024 00:00:00 UTC To accumulate values from a MySQL query inside a while loop and then calculate the total value outside the loop, you can use a variable to store the total value while iterating through the records. Here’s an example in PHP: <?php // Your database connection parameters $servername = "localhost"; $username = "your_username"; $password = "your_password"; $database = "your_database"; // Create a connection to the MySQL database $conn = new mysqli($servername, $username, $password, $database); // Check the connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } $totalValue = 0; // Initialize total value // Your SQL query $sql = "SELECT value_column FROM your_table_name WHERE your_conditions"; $result = $conn->query($sql); if ($result->num_rows > 0) { while ($row = $result->fetch_assoc()) { // Access value column and accumulate the values $value = $row['value_column']; $totalValue += $value; // You can also store values in an array if needed // $valuesArray[] = $value; } echo "Total value: $totalValue"; // Print total value // If you stored values in an array, you can print or manipulate the array here // print_r($valuesArray); } else { echo "No records found."; } // Close the database connection $conn->close(); ?> This PHP script fetches records from the database, accumulates the values from a specific column (value_column), and calculates the total value by adding up these values inside the while loop. After the loop, it prints the total value obtained. If you need to store these values in an array for further processing, you can uncomment and modify the $valuesArray[] = $value; line accordingly.
