Getting value from input when using JToolbarHelper::custom Topic is solved

[drussell1974]

I am the following the tutorial https://docs.joomla.org/Creating_a_tool ... _component, but cannot get the selected value from my dropdown (or other inputbox). I am using Joomla 3.9 with php7.2.11.

How do use get (or other methods) to retreive the value from the input?

views\learningobjectivepathway\view.html.php
The toolbar actions appear correctly and calls the action in the controller.

Code: Select all

JToolbarHelper::title($title, 'learningobjectivehaspathway');
        JToolbarHelper::save('learningobjectivehaspathway.save');
        JToolbarHelper::cancel('learningobjectivehaspathway.cancel', $isNew ? 'JTOOLBAR_CANCEL' : 'JTOOLBAR_CLOSE' );
        JToolbarHelper::custom('learningobjectivehaspathway.wizardPrev', 'previous', 'previous', JText::_('COM_SCHEMEOFWORK_LEARNINGOBJECTIVEHASPATHWAY_WIZARD_PREV'), false);
        JToolbarHelper::custom('learningobjectivehaspathway.wizardNext', 'next', 'next', JText::_('COM_SCHEMEOFWORK_LEARNINGOBJECTIVEHASPATHWAY_WIZARD_NEXT'), false);}

models\forms\learningobjectivehaspathway.xml
I want the value from the topic_id field.

Code: Select all

<fieldset
        name="details"
        label="COM_SCHEMEOFWORK_LEARNINGOBJECTIVEHASPATHWAY_DETAILS"
    >
        <field
            name="id"
            type="hidden"
        />
        <field
            name="topic_id"
            type="Topics"
            extension="com_schemeofwork"
            class="inputbox"
            default="0"
            label="COM_SCHEMEOFWORK_LEARNINGOBJECTIVE_TOPIC_LABEL"
            description="COM_SCHEMEOFWORK_LEARNINGOBJECTIVE_TOPIC_DESC" 
            required="true"
        >
            <option value="0">COM_SCHEMEOFWORK_LEARNINGOBJECTIVEHASPATHWAY_JOPTION_SELECT_TOPIC_NAME</option>
        </field>

controllers/learningobjectivehaspathway.php
When using get I have tried $jinput->post->get and $jinput->get and for the variable name I have tried "topic_id", including "jform_topic_id" and "jform[topic_id]" as display in from id and form name from the html.

Code: Select all

class SchemeOfWorkControllerLearningObjectiveHasPathway extends JControllerForm {
   public function wizardNext()
   {
        $jinput = JFactory::getApplication()->input;
        var_dump($jinput);
        $item = $jinput->post->get('topic_id', '', 'STR');
        var_dump($topic_id);
   }
}

var_dump from $topic_id
The default is being returned each time from the var_dump($input_id)

Code: Select all

string(0) ""

var_dump from $jinput
The value input_id has it's value set in the outfrom from var_dump($jinput)
Though, I noticed the arrays are protected. Has this got anything to do with not being able to retreive the value? How do I get round it? Am I missing something obvious?

Get the form data array and then get the topic_id:

Code: Select all

$data = $this->input->get('jform', array(), 'array');
$item = $data['topic_id'];

Get the form data array and then get the topic_id:

Code: Select all

$data = $this->input->get('jform', array(), 'array');
$item = $data['topic_id'];

Thank you! That works a treat.

My amended code...

controllers/learningobjectivehaspathway

Code: Select all

class SchemeOfWorkControllerLearningObjectiveHasPathway extends JControllerForm {
   public function wizardNext()
   {
        $data = $this->input->get('jform', array(), 'array');
        $topic_id = $data['topic_id'];
        var_dump($topic_id);
   }
