repeatly passing objects to the same page?

[AlienX]

Let say I am trying to get a list of schools, and I provide a form for ONE school/page.

If the user wants to add one more school, he/she can press "add" and it will loop back to the same php page and php script should construct an object "school" based on the data he/she entered in the form and add the object into an array.

If the user has entered all the school infos, he/she can press "done" and the php script should flush the array of "school" objects into a db.

My main question: how can I pass the array of objects back to the same page?

You could store them in a session. Minor caveat: the object class has to be loaded before session_start() is called, or the object will lose it's type.

well, the usual way you do something like this is:

1.) you have a form with some fields, say 'myform.php'

2.) the action attribute of the form tag points to 'myform.php'. so when you submit the form the same php-script gets called.

3.) in your script you check if the http request is GET or POST ($_SERVER['REQUEST_METHOD']). if it is a POST you have to validate all the fields. if the validation fails, you display an error message and output the values the user has entered again in the form. if the entered data is valid you insert them into your database and after that you do a redirect to the page that lists all the entries.

This way you don't have to "cache" anything somewhere.
