params

I have to add a new param to an indeterminate URL, let's say param=value . In case the actual URL has already params like this http://url.com?p1=v1&p2=v2 I should transform the URL to this other: http://url.com?p1=v1&p2=v2&param=value But if the URL has not any param yet like this: http://url.com I should transform the URL to this other: http://url.com?param=value I feel worry to solve this with Regex because I'm not sure that looking for the presence of & could be enough. I'm thinking that maybe I should transform the URL to an URI object, and then add the param and transform it to String

What's the best way to pass some params along with a redirect? I saw examples that said if you just add them to your redirect hash they would pass along with the request, but that doesn't seem to work anymore in Rails 3. In my example I have an 'edit multiple' page that lets a user change the category on multiple items at once. Because they're browsing so many items this form is paginated. If a user is on items page 3 , makes some changes and presses sumbit, then the controller action receives a post request with the ids of the records that were changed, makes the changes, and redirects to the

I like all the default routes that are generated by Rail's map.resources . But, there are cases where I would like to use a non-numeric identifier in my routes. For example, If have a nested route consist of users and their articles, a standard route could be written as such: map.resources :users, :has_many => [:articles] # => e.g. '/users/:id/articles/:id' However, there are many advantages / reasons not to use the default numerical identifier generated by Rails. Is there a way to replace the default :id params to another canonical identifier of my choice without resulting to writing custom

I have a php file that needs to redirect to another, but I need to pass an array to the second file. How can I do this. I know this is wrong, but I need something logically similar to this. <?php $arr = array('this'=>'is', 'some'=>'stuff'); header("someurl.php", vals=>$arr); ?> If you don't want to expose your $array, you MUST use PHP inbuild session support. session_start(); // DO CALL ON TOP OF BOTH PAGES $_SESSION['array'] = $array; echo $_SESSION['array']; // GIVES SAME $array FOR BOTH PAGES Halcyon Use http_build_query : header("Location: someurl.php?" . http_build_query($arr)); That's
