I am just starting with Joomla component development and MVC in general. Im also not incredibly strong in PHP but I am trying to build a component that gets json and displays it as a jQuery accordion list.
I started by creating a PHP script that does just that and it works fine.
Now Im on the component part and the mvc is tripping me up. I adapted the hello world component in the docs tutorial found here: http://docs.joomla.org/Developing_a_Model-View-Controller_Component/3.1/Introduction
But when I install the component and go to my component I get:
Fatal error: Call to undefined function getProject() in /[path to joomla]/components/com_insightly/views/insightly/view.html.php on line 23 So my view cant use a function I defined in my model. I must be missing something because I thought the controller assigned the model to the view auto-magically.
Here is some source, (sorry im not indenting 8 spaces on each line manually)

Also I welcome the pointing out of any other blaring mistakes and security flaws.
EDIT: the idMask function was removed in my post due to sensitive content. It is probably not the issue.
EDIT: I have the component loading now and have updated the code but I'm having trouble with the arrays. taskStyler should return an array to be set to $completed_tasks[i].
completed_tasks[0][0] is correct but completed_tasks[0][1] contains an array composed of what should becompleted_tasks[0][1-12].
This is my current version of the relevant functions:
Calls getTasks and compiles array of tasks that are in progress
public function getActiveTasks($user_id){ $project_tasks = $this->getTasks($user_id); $tasks = $this->loopAndFind($project_tasks, 'STATUS', 'IN PROGRESS'); $i = 0; foreach ($tasks as $key=>$value){ $active_tasks[$i] = $this->taskStyler($key, $value); $i++; } return $active_tasks; } Calls getTasks and compiles array of tasks that are completed
public function getCompletedTasks($user_id){ $project_tasks = $this->getTasks($user_id); $tasks = $this->loopAndFind($project_tasks, 'STATUS', 'COMPLETED'); $i = 0; foreach ($tasks as $key=>$value){ $completed_tasks[$i] = $this->taskStyler($key, $value); $i++; } return $completed_tasks; } Curl session with API server that returns an array of tasks (known to work perfectly)
public function getTasks($user_id){ $task_url = 'https://api.insight.ly/v2/tasks'; $curl = curl_init($task_url); curl_setopt($curl, CURLOPT_HTTPHEADER, array( 'Content-Type: application/json', 'Authorization: Basic Dontlookatmypassword') ); curl_setopt($curl, CURLOPT_HEADER, 0); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); $curl_response = curl_exec($curl); if ($curl_response){ $decoded = json_decode($curl_response, true); $project_tasks = $this->loopAndFind($decoded, 'PROJECT_ID', $user_id); return $project_tasks; } else { die('An Error occurred retrieving Tasks. Additional info: ' . curl_error($curl)); } curl_close($curl); } Returns an array representing a datafield of a task with the keys and some values edited for readability, and html tags, classes and ids appended.
public function taskStyler ($key, $value){ $html_tag = "li"; $html_class = null; $html_id = null; switch ($key) { case "Title": $key = "Task"; $html_tag = "h3"; break; case "DUE_DATE": $key = "Due Date"; $value = $this->dateFormatter($value); break; case "COMPLETED_DATE_UTC": $key = "Date Completed"; $value = $this->dateFormatter($value); break; case "DETAILS": $key = "Details"; $value = strip_tags($value); break; case "STATUS": $key = "Status"; break; case "PERCENT_COMPLETE": $key = "Percent Complete"; $value = $value . "%"; break; case "START_DATE": $key = "Start Date"; $value = $this->dateFormatter($value); break; case "RESPONSIBLE_USER_ID": $key = "Assigned to"; $value = $this->idMask($value); break; default: $value = null; } if ($value) { $task = [$key, $value, $html_tag, $html_class, $html_id]; } else{ $task = null; } return $task; }
