Problem with my implementation of the Post/Redirect/Get pattern

阅读更多关于 Problem with my implementation of the Post/Redirect/Get pattern

问题 I always use the Post/Redirect/Get method on my forms. My forms generally always submit to themselves. However, when I have an error in the form, I don't send any new headers. This is so I can easily do stuff like this <input type="text" name="email" value="<?php echo $this->input->post('email', '') ?>" /> The PHP is just a library function that handles 2 arguments, the $_POST key and a default value if it isn't present. This means if someone makes an error in the form, they don't have to

问题 I have a simple three page asp.net webforms site and having an issue with the back browser button that throws the popup "...Firefox must send any information that will repeat any action.." when hitting back on the step3.aspx.

阅读更多关于 Laravel 4: Prevent multiple form submissions - CSRF Token

问题 Problem scenario: I'm creating a blog with Laravel 4. The form that's responsible for the creation of new blog posts is secured by the build in CSRF protection (Laravel Docs: CSRF Protection). Everything works fine so far, but it seems that laravel does not refresh the csrf token on every request. The problem that occurs is that if the user hits the back button of the browser to return to the submitted form, the entered data persists and the user is able to "re-submit" the form. This might

阅读更多关于 Post Redirect Get in ASP.NET MVC And Validation With Restful URLs

问题 I have a restful URL for the action of editing a page. This is implemented on the controller as an Edit method, which accepts GET requests and an Edit method that accepts POST requests. This means you can visit the Edit URL and it will display a form for a GET or save a form for a POST. [HttpGet] public ActionResult Edit(int id) { ... } [HttpPost] public ActionResult Edit(EditModel model) { ... } The Post-Redirect-Get (PRG) pattern seems pretty black and white, because it essentially
