Redirect to another page: window.location.replace("manage_news.php"); After the user clicks "OK" on the alert, the browser will navigate to manage_news.php (presumably a news management page).
This line of code is using PHP's echo statement to output a JavaScript code block that performs two actions:
Display an alert popup:
alert("News article has been updated successfully");
This shows a browser alert with the message "News article has been updated successfully".
Redirect to another page:
window.location.replace("manage_news.php");
After the user clicks "OK" on the alert, the browser will navigate to manage_news.php (presumably a news management page).
Why This is Used:
This is typically seen in a PHP script (e.g., after updating a news article in a database) to notify the user of success and then redirect them back to a management page.
window.location.replace() is used instead of window.location.href to ensure the current page (update_news.php or similar) is not stored in browser history, preventing back-button issues.
