PHP的编辑按钮更好的形式或href链接？

Question

I'm just curious what is the better method for edit buttons in an admin, keeping in mind the there could possible be 100s of these edit buttons on a page,

a form to use the POST variables

<form action="" method="POST" enctype="multipart/form-data" target="_self">
  <input type="hidden" name="ID" value="123" />
  <input type="hidden" name="name" value="ABC" />
  <button type="submit" name="action" value="Edit" class="edit></button>

or a href to use the GET variables

<a href="?action=Edit&ID=123&Name=ABC" class="edit">Edit</a>

I'm just curious in regards to speed and usability. Any opinions welcome.

Answer 1

Server Side

Edit button or form button do not impact server side processing at all.

If you are looking to reduce the html file size , the get variable based approach could help and reduce that less than 5% extra overhead (can vary based on type of application).

Client Side

The % impact on client side will also be negligible based on how browser handles the submit action.

Side Notes

• href links work only as a replacement for GET forms and not for POST.

• url based approach is useful in cases like edit button where there is no user modified input

Answer 2

Even better is using the HTTP PATCH method which meant to represent partial resource modification.

You should avoid using GET requests when the outcome alters a resource (because the request will be resent by hitting the back button).

However since many browsers cannot send native PATCH requests you need a bit of trickery. Ruby On Rails for example uses javascript together with a method POST parameter to fake PATCH , PUT and DELETE requests - even on links.
