I never actually had the need to use plugin priority, but I'll try to have a look. It would be nice if you could specify/provide the plugins you are using, to facilitate problem reproduction.

The plugins are the ones I developped.
I'm not sure my need was clear :

My plugin A adds a field in the issue thanks to "EVENT_VIEW_BUG_DETAILS"
My plugin B also adds a field.
I want the following order :

• field created by plugin B
• field created by plugin A

And it's not the case. So, if priority can't help me, when this value is used ? Is there a way to order my plugin fields ???

EDIT (dregad): changed 'had' to 'add' per mboutell's request

I think it was clear from the start, but thanks for updating anyway.

The reason for my request, is that if indeed the priority should impact the order in which fields are displayed, then it would be helpful and better to have existing, real-life code to test that the feature works as expected, rather than having waste time to write dummy test plugins for that.

As far as I know, priorities determine the order in which plugins are registered, and therefore (in theory) the order in which the callback are executed. In addition, for events of type "first", callbacks processing will stop after the first non-null value is returned.

I have tested with my installed plugins, wich also uses EVENT_VIEW_BUG_DETAILS
Priority does change the order of the output from the plugins.
Note that a higer priority, eg: 5 will cause this plugin to be executed before another one with lower priority, eg: 1

As far as i know, this hasn't been changed from mantis 1.2.x to 1.3.
I think you have misunderstood the priority precedence.

I'm sorry but I used 5 for my plugin B and 1 for my plugin A and my plugin B is still called before (At least the fields from plugin A are displayed before the ones of plugin B)
Before creating this issue I've tested many values ;)

Im sorry but I used 5 for my plugin B and 1 for my plugin A and my plugin B is still called before

Thats exactly the behaviour i described: plugin B with priority=5 executes before plugin A with priority=1

(At least the fields from plugin A are displayed before the ones of plugin B)

That's contradictory, you said "plugin B was called before A"

Exactly my answer was contradictory :
Currently :
Plugin A : priority 1
Plugin B : priority 5

the plugin A is called before my plugin B

(sorry for my last answer)

Any other suggestion ? Still can't use priority...

Is there something to activate ? I can't find where the priority is used in the code.
Any support? It's very important. Thank you

I still can't choose the priority of my plugins.
Any help ?

Hello,

I took the time today to create a couple dummy plugins to test this. They simply display the plugin's name and assigned priority when EVENT_VIEW_BUG_DETAILS is sent.

Here is the source code (the only difference between the 2 plugins being their name)

<?php
class p1Plugin extends MantisPlugin {
    function register() {
        $this->name = 'Test 1';
        $this->version = '1.0';
    }

    function hooks() {
        return array( 'EVENT_VIEW_BUG_DETAILS'  => 'view' );
    }

    function view( $p_event, $p_bug_id ) {
        printf( "<div>%s (priority %d)</div>", $this->name, plugin_priority(plugin_get_current()) );
    }
}

After installing the 2 plugins, I tested as follows, by setting:

1. plugin 1 with priority 1 and plugin 2 with priority 3
2. changed plugin 1 priority to 5, left plugin 2 with priority 3

As shown in the attached screenshot, the system works as expected, i.e. the plugin with the higher priority displays first
