Executing PHP Code on Link Click without Redirect
Running PHP code upon user interaction is a common website requirement. One such scenario is triggering a script when a user clicks a link without navigating away from the current page.
Can it be done with Anchor Tags (
Using standard HTML anchor tags limits your options. Clicking the link results in a page redirect, preventing the execution of PHP code.
Using JavaScript's onclick Event
JavaScript's onclick event provides a way to trigger custom actions on link clicks. However, the default behavior still redirects the browser.
Solution: AJAX with JavaScript
To achieve this goal, we need to employ AJAX (Asynchronous JavaScript and XML). Using a JavaScript function triggered by onclick, we can issue an AJAX request to a PHP script without reloading the page.
jQuery Example
If using jQuery is acceptable for your project, the following code sample demonstrates the approach:
This will trigger the doSomething() function, which sends an AJAX request to somepage.php and returns false to suppress the redirect.
Note for Form Values
If your PHP code requires access to form values, consider using the $.post() method instead of $.get() for a post-back.
