Getting value from input when using JToolbarHelper::custom
Posted: Thu Nov 29, 2018 6:15 am
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.
models\forms\learningobjectivehaspathway.xml
I want the value from the topic_id 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.
var_dump from $topic_id
The default is being returned each time from the var_dump($input_id)
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?
