Post to an action URL fails, Get works

Question

I have a simple plugin that's expected POST data from a form:

<form method="post" action="" accept-charset="UTF-8">
    <input type="hidden" name="action" value="{{ actionUrl('broadbean/jobs/new') }}">

When I submit the form, that fails:

Page Not Found

Unable to resolve the request "http:/craft.dev/index.php/admin/actions/broadbean/jobs/new".

If I cut and paste that URL into a new window, I get the plugin response, so what gives here? The plugin is set up to allow anonymous access (but I'm submitting the form from within an admin view anyway).

EDIT:

According to http://buildwithcraft.com/docs/plugins/controllers#posting-to-controller-actions I should be able to put the action URL in a hidden field, which I've done. If I dispense with that and instead put the actionUrl() directly in the form's action parameter, everything works.

Is this a bug? This is on Craft 2.2.2601.

EDIT:

Controller code:

class Broadbean_JobsController extends BaseController
{
    protected $allowAnonymous = true;

    public function actionNew()
    {    
        $this->requirePostRequest();

        $result = craft()->broadbean_jobs->createJob();

        var_dump(array(
            'message' => ($result['success']) ? Craft::t('Job created.') : Craft::t('Unable to create job.'),
            'values' => craft()->request->getPost(),
            'errors' => $result['errors']
        ));

    }
}

Answer 1

I believe that when you post data using name='action' from a form that craft automatically uses the actionUrl to route the request properly, so that if your controller is here:

/craft/plugins/broadbean/controllers/Broadbean_JobsController.php

with a method actionNew, then craft will create the action route broadbean/jobs/new automatically:

<input type="hidden" name="action" value="broadbean/jobs/new">

On the other hand if you are linking directly then craft doesn't know to use the action route, so you need to explicitly tell it that this is an action request:

<a href="{{ actionUrl('broadbean/jobs/new', { id: 10 }) }}">

or from javascript:

var url = Craft.getActionUrl('broadbean/jobs/new', { id: 10 });

If you were to call the action externally then you would have to write the full action url without the benefit of using the automatic config routing:

http://mysite.com/actions/broadbean/jobs/new?id=10

or, if the admin had, for example, set up a custom actionUrl in the config file:

http://mysite.com/methods/broadbean/jobs/new?id=10

You may need to set up a route using this Hook Reference from the plugin docs:

http://buildwithcraft.com/docs/plugins/hooks-reference#registerCpRoutes

function registerCpRoutes()
    {
        return array(
        'cocktails/new'               => 'cocktails/_edit',
        'cocktails/(?P<widgetId>\d+)' => array('action' => 'cocktails/editCocktail'),
    );
}
