PHP Session for Tag Groups – what does it do?

    Hi,
    I’ve got a conflict between Tag Groups and my theme – this appears to be related to the cookie that Tag Groups creates. I’m not an expert so could you say what this actually does and what happens if I disable it? (Everything seems to still work OK if I do!)
    For reference:
    The Next and Previous month links here stop working due to the conflict
    The theme developer has suggested to me that it is due to a conflict with Tag Groups
    Here are the tag groups still functioning whilst session_start(); is commented out in tag-groups.php. This is the only place they’re in use on the site.

    The session is used to save the state of the filter.

    Could you please check if, instead of commenting out, the following modification helps as well:

    if ( !isset( $_SESSION ) ) {
    	session_start();
    }

    Thanks

    Thanks for the swift reply. No, I’m afraid that if I use that the calendar stops working again.
    When you say the cookie saves the state of the filter, is this if using multiple tags to filter on? As I said, with the session disabled it still works for me.

    Really difficult to debug without having the theme…

    Possible another modification:

    if ( !session_id() ) {
	session_start();
}

    The filter I mentioned is only relevant for admins on the tags page. There should be no problem on the frontend resulting from deactivating that session_start thing, particularly since the theme seems to start it already.

    In the worst case I could just add an option to the settings to deactivate the filter.

    Please try the latest version. There is also a new option in the settings to turn off the filter on the tag admin page, which should have the same effect as commenting out session_start.

    It’s better than editing the code because updates would then overwrite your changes.
