Developing Plugin, wp_options data gets erased

    Forgive me if this has been discussed before, I search around the forums and did not find anyone else that has posted this problem

    I am developing a plugin. I stored all my options into an array, serialize it, and save it into a field in the wp_options table using the add_option() function, or the update_option() when updating my plugins options.

    This works great. However I have encountered a problem where when I went to reset the time and date on my wordpress blog, after saving it my options in the wp_options table for my plugin were reset to: s:2:”N;”;

    It also did this when I changed the privacy settings on my blog. So I’m guessing this happens anytime a WordPress setting is changed.

    Is there a hook or something else I need to do to have my options in wp_options saved when a WordPress setting is changed?

    I’ve been looking through the source code of other plugins and I don’t see where they may be doing something like that, but there is a lot of code and I could be over looking it.

    By the way, I am using wordpress 2.7.1, I don’t know if this occurs on other wordpress versions.

    Thanks!

    Guys and Gals,

    I discovered my problem, I’m sorry for posting this issue as it was a logic error in my plugin. I’ve been working on this way too long today and I’m at the point I’m making stupid mistakes 🙂

    I’ll explain what happened in case it may help someone else in the future.

    In my plugin, I had a line of code that checked when the management page of my plugin submitted the form to update the plugin’s options, like this:

    if($_POST['action'] == 'update')
{
	// we are saving my_plugin options from my_plugin_manager.php
	$sl->SaveOptions($_POST["my_plugin_options"]);
}

    The problem is that anytime a setting is updated under the Settings menu on wordpress, $_POST[‘action’] == ‘update’ is always true.

    I needed to pass a hidden form variable as an identifier so that it would only update when the form was submitted from my plugins management page, like so:

    if($_POST['action'] == 'update' && $_POST['my_plugin_update'] == 1)
{
	// we are saving my_plugin options from my_plugin_manager.php
	$sl->SaveOptions($_POST["my_plugin_options"]);
}
