Content plugin with more than one tab in article edit view

Question

i am making a simple content plugin using the joomla 3 docs.

However i want more than 1 tab to appear.

here are my main files. Plugin is installed an runs succesfully but only one tab will ever appear.

extras.php

// no direct access
defined ( '_JEXEC' ) or die ( 'Restricted access' );
class plgContentExtras extends JPlugin {

// the language file would have to go into languages folder

        protected $autoloadLanguage = true;

        function onContentPrepareForm($form, $data) {
                $app = JFactory::getApplication();
                $option = $app->input->get('option');
                switch($option) {
                        case 'com_content':
                                if ($app->isAdmin()) {

                                        JForm::addFormPath(__DIR__ . '/forms');
                                        $form->loadFile('extras', true);

                                }                           

                                return true;
                }
                return true;
        }
}

forms/extras.xml

<?xml version="1.0" encoding="UTF-8"?>
<form>
        <fields name="params">
                <fieldset name="params"  label="Map" >
                        <field
                                name="mapinfo"
                                type="text"
                                label="Map Info"
                                />

                </fieldset>

                <fieldset name="params"  label="eBlast" >
                        <field
                                name="eblastinfo"
                                type="text"
                                label="Eblast Info"
                                />

                </fieldset>

        </fields>   

</form>

Thanks to anyone in advance for your help :)

ps: i am a novice to this.

I did also try adding an extra $form->loadFile('eblast', true); to the extras.php file and then creating an extra file called eblast.xml within the forms/ folder but that didnt work either.

This is because you have assigned the same name to both <fieldset> tags. Each one must have a different name, for example:

<fieldset name="map" label="Map">
    <field
        name="mapinfo"
        type="text"
        label="Map Info"
    />
</fieldset>

<fieldset name="eblast" label="eBlast">
    <field
        name="eblastinfo"
        type="text"
        label="Eblast Info"
    />
</fieldset>

You will see I've used name="map" and name="eblast".

Update:

To access the parameters, you can simply use the following:

$this->params->get('mapinfo');
$this->params->get('eblastinfo');

Hope this helps
