Use the Slim application’s delete() method to map a callback function to a resource URI that is requested with
the HTTP DELETE method.
<?php
$app = new \Slim\Slim();
$app->delete('/books/:id', function ($id) {
//Delete book identified by $id
});
In this example, an HTTP DELETE request for “/books/1” will invoke the associated callback function, passing “1” as the callback function’s argument.
The first argument of the Slim application’s delete() method is the resource URI. The last argument is anything that
returns true for is_callable(). Typically, the last argument will be an anonymous function.
Unfortunately, modern browsers do not provide native support for HTTP DELETE requests. To work around this limitation, ensure your HTML form’s method attribute is “post”, then add a method override parameter to your HTML form like this:
<form action="/books/1" method="post">
... other form fields here...
<input type="hidden" name="_METHOD" value="DELETE"/>
<input type="submit" value="Delete Book"/>
</form>
If you are using Backbone.js or a command-line HTTP client, you may also override the HTTP method by using the X-HTTP-Method-Override header.
