    Hello!
    First of all, very nice plugin!
    I have an issue though..I want to use session_start(); inside the widget but it seems that it is not recognized for some reason…I say that because I used var_dump to see if php code above and after it is executed – var_dump of the code above session_start(); returns non-empty array, while var_dump/print_r of $_SESSION; returns Array ( )…

    When I execute the whole code outside wordpress, just via php pages, all run smoothly…

    Is it not supported?
    Can we dubug this?

    Thank you in advance!

    Because the normal behavior of session_start() is to use cookies, and cookies have to occur before any output is printed, then no, you really can’t use session_start in a widget like that.

    Hello,
    thank you for your reply.
    We want to set up a subscription process.
    So basically, I will have to see how wordpress handles sessions so as to get the data from a wordpress variable, right?

    WordPress does not use PHP Sessions at all. If you want to use them, best to write a plugin for that.
