POHow best to pass a message for the user between pages
text
Body
copied!<p>So the chain of events is:</p> <ol> <li>The user submits a form.</li> <li>During the processing of the submission, there is a message generated, such as "Your record was saved."</li> <li>The user is redirected to a new page, say the search results.</li> <li>The new page needs to display the message.</li> </ol> <p>So, the question is how to get the message from step 2 to step 3? This is only one simple example...there are many other much more complicated examples.</p> <p>I am using PHP.</p> <p>Needs:</p> <ul> <li>supports multiple messages and need to be formatted on the receiving machine as required</li> <li>messages can be added on the same page (such as within step 4)</li> <li>messages added from inside any function or object</li> </ul> <p>Some options I have come up with:</p> <ul> <li>store in a session variable as an array and emptied after each display</li> <li>pass as a get or query parameter; can get annoying as you are constantly processing this and have to remember to get it; as it can get long, it could easily go over the max length of the query string</li> <li>store in the database on a per session basis (may not always be for a logged in user); this would require an extra insert on each page where they are added, possibly multiple, and an extra select on every page</li> </ul> <p>Currently I have been storing the messages in the session in an array, but I'm wondering if there is a better way. I don't think the other 2 options above are very good.</p> <p><strong>Edit:</strong> I use 2 functions for the session method: AddStatusMsg() (adds an element to the array) and DisplayStatusMsg() (returns an HTML formatted message and empties the array).</p>
