I think it's ASC, so 15 then 25 then whatever number is bigger than 25.

Plugins and their events get sorted by priority.

EdB is right about ASC.

Cool.....

But for rendering, if i have my plugin's priority less than the auto_p plugin's then it will run after the auto_p plugin....

Cannot confirm.

You've probably just have changed the $priority property of the plugin (in the class file), but not edited the installed plugin (or clicked on "Restore defaults").

Priority ordering takes place only from DB.

Yeh, looking the database priority values right now.

Plugin's that have a priority that is lower than the auto_p plugin are run after the auto_p plugin.

You can see this with the youtube plugin, there will be w3c warnings if youtube plugin renders before the auto_p plugin as the auto_p plugin will stick <p> tags in odd spots...

Or with my gallery plugin....

Well that's how it is for me right now....

Just tested it on my local and remote blog and seems that i'm mistaken...

Although when i change my gallery plugin's priority to 80 instead of 60, with the auto_p plugin's priority being 70, i start getting a extra </p> which causes a fair few display warnings.

So is this happening becaues the auto_p plugin sees:
[evo_gallery]214124[/evo_gallery]
And then thinks it's normal text and sticks it in a paragraph?

And also, say for a certain plugin definied event, i want the plugins that contain the event to fire in a particular order. How would i do this?
I was thinking just replace their priority during the event, and then set it back after. But you just said that only the DB priority matters, so that would invovle the DB being updated....

Sure.

Please explain, why.

But you should be able to set plugin priorities (their member values) and than call ->sort() on the Plugins object that holds them.

For the Panels, you can re-order them, and instead of the Panels Plugin calling each one individually, it would be easier just to set their priorities.

As the panels can be in different orders for different blogs/users etc.

But yeh, should work then.

..and when you set their priorities, why shouldn't that get stored into DB?

Because the positions are customizable by the user visiting the blog.
The administrator of the blog just choses the default positions.
