Sending multipart/form-data with PUT request doesn't work in Laravel

December 8, 2021

I am trying to send an HTTP PUT request with "Content-Type": "multipart/form-data" to a Laravel application. When I change the method to POST it works.

$a = $request->all(); // With PUT this is empty but with POST it works fine.

The client-side executes the following code:

axios({
    method: "post", // when I try method:"PUT" and change the content type 
    url: "/api/offer",
    data: fd,
    headers: {"Content-Type": "multipart/form-data"} // here change to "x-www-form-urlencoded" it the $a array on backend is empty! 
}).then(response => {
    console.log("/offer/" + response.data)
    if (response.data)
        window.location.replace("/offer/" + this.offer.id);
    else {
        console.log("show a message that something went wrong! ")
    }
}).catch(function (error) {
})

I could not find anywhere in the docs that PUT can’t send "multipart/form-data"

So, can PUT send "multipart/form-data" or only POST can do that in general or it is only a PHP / Laravel Issue?

Edit:
Also, what difference does it make to use PUT instead of POST other than to comply with HTTP protocol and CRUD operation properly?

>Solution :

Laravel (HTML Forms) do not work great with Put requests so you’ll need to spoof a POST request as if it was a PUT or PATCH request. On Axios you use the .post verb but within your form data you append

_method: "put"

Information from the official documentation:
https://laravel.com/docs/8.x/routing#form-method-spoofing

Excerpt from the documentation:

HTML forms do not support PUT, PATCH, or DELETE actions. So, when defining PUT, PATCH, or DELETE routes that are called from an HTML form, you will need to add a hidden _method field to the form. The value sent with the _method field will be used as the HTTP request method
