How can you override the method of a form with a button?
Jun 22, 2025 am 12:50 AM
You can override a form’s method using a button through three main approaches. 1) Use a hidden input field (e.g., _method) with frameworks like Laravel to simulate methods like PUT or DELETE when the actual method is POST. 2) Employ JavaScript to dynamically change the form’s method before submission, allowing different buttons to trigger different actions. 3) Use multiple forms with distinct methods for simplicity and reliability, especially when actions are clearly separated. Hidden inputs are widely supported without JavaScript, while JavaScript offers flexibility but depends on backend support. Multiple forms avoid overrides entirely. Always verify backend compatibility and note that browsers natively support only GET and POST for form submissions.
In HTML and web development, you can't directly "override" a method like POST or GET using a button in pure HTML alone. However, there are common workarounds—especially when dealing with frameworks like Laravel, Ruby on Rails, or even plain PHP—that allow you to simulate overriding the HTTP method. This is often needed when building forms that need to perform actions like PUT or DELETE in environments that only support GET and POST natively.
Here’s how you can effectively override a form's method using a button.
Use a hidden input field for method override
Most backend frameworks support method override via a special hidden input field. For example:
<form method="POST" action="/update-profile"> <input type="hidden" name="_method" value="PUT"> <!-- other form fields --> <button type="submit">Update Profile</button> </form>
Frameworks like Laravel will interpret the
_methodinput and route the request as if it were a PUT request, even though the actual HTTP method used was POST.
This is a widely supported approach and doesn’t require JavaScript.
Use JavaScript to change the form method dynamically
If you want more control and flexibility—like having multiple buttons that trigger different methods—you can use JavaScript to modify the form’s method before submission.
<form id="myForm" action="/some-endpoint">
<!-- form fields -->
<button type="button" onclick="submitAs('GET')">View</button>
<button type="button" onclick="submitAs('POST')">Save</button>
</form>
<script>
function submitAs(method) {
const form = document.getElementById('myForm');
form.method = method;
form.submit();
}
</script>This approach gives you the ability to choose the HTTP method based on user interaction, but keep in mind that not all backends respect method changes from JavaScript unless they're explicitly set up to handle them.
Use multiple forms for different actions (simple and reliable)
Sometimes the simplest way is to just use multiple forms, each with its own method. This avoids any confusion or reliance on overrides.
<form method="POST" action="/create"> <button type="submit">Create</button> </form> <form method="POST" action="/delete"> <input type="hidden" name="_method" value="DELETE"> <button type="submit">Delete</button> </form>
This works especially well when you have clearly distinct actions and don’t want to overcomplicate things with JavaScript or hidden fields.
A few notes and gotchas
- Always check your backend framework documentation to see how it handles method override.
- Browsers only support GET and POST natively for form submissions.
- The most commonly used override parameter is
_method, but some systems might use something else likeX-HTTP-Method-Override. - Using JavaScript to change the method may not be respected by all servers unless handled explicitly.
That's how you can effectively override the method of a form using a button — either through hidden inputs, JavaScript, or multiple forms. It's not complicated, but it does depend a bit on your backend setup.

Change the power button action on Windows 11 [5 Tips]
Sep 29, 2023 pm 11:29 PM
The power button can do more than shut down your PC, although this is the default action for desktop users. If you want to change the power button action in Windows 11, it's easier than you think! Keep in mind that the physical power button is different from the button in the Start menu, and the changes below won't affect the operation of the latter. Additionally, you'll find slightly different power options depending on whether it's a desktop or laptop. Why should you change the power button action in Windows 11? If you put your computer to sleep more often than you shut it down, changing the way your hardware power button (that is, the physical power button on your PC) behaves will do the trick. The same idea applies to sleep mode or simply turning off the display. Change Windows 11

In iOS 17, Apple not only added several new messaging features, but also tweaked the design of the Messages app to give it a cleaner look. All iMessage apps and tools, such as the camera and photo options, can now be accessed by tapping the "+" button above the keyboard and to the left of the text input field. Clicking the "+" button brings up a menu column with a default order of options. Starting from the top, there's camera, photos, stickers, cash (if available), audio, and location.
