Set session variable

[rolwong]

Let say I have a page and there is a textarea and some button link. I'd like to know if it is possible to store the text as a session variable whenever the user leaves the page. I don't want to use POST / GET method to send the text to other page (when user click the button link) and then set SESSION in every pages.

sorry truti, i don't think it is possible. PHP is server side - so to set a session var, the data to go into the session has to be sent from the client to the server - either in GET or POST methods.

what you can do is send the form without a button - you can use javascript to call the form.submit() method without a button

(when user click the button link)

If the user is clicking a button, or anything for that matter, it could easily be a 'submit'. The submit could then be used to store the SESSION variable.

The key is the phrase "whenever the user leaves the page.

You could only store if the user leaves by way of the button.

POST the form to itself and then set the variable and use headers to redirect to another page.
