Codeigniter - controller can't send data to view

Controller

public function show() { $this->$data['tasks'] = array(); $this->$data['tasks'] = $this->Tasks_model->show_task(); $this->load->view('pages/all', $data); } 

View

//Here, you can also use for loop to display data.

<?php if( isset($tasks) && ( is_array($tasks) && count($tasks)>0 ) ) { //echo"<pre>"; print_r($tasks); die(); for($i=0;$i<count($tasks);$i++) { ?> <span><?php echo $task[0]['job']; ?></span><br /> <?php } ?> <?php } else { ?> <span>No tasks records found.</span> <?php } ?> 

EDIT =>

Model

public function show_task() { $query = $this->db->get('task'); if( $query->num_rows() > 0 ) //Always check you are getting result or not. { return $query->result_array(); //result_array() returns the query result as a pure array } else { return array(); } } 

Here you are returning return $this->db->get('task'); directly. So you are not getting anythingin View. First you have to assign $this->db->get('task') to variable e.g. $query and pass result array to controller return $query->result_array();.

Controller:

 public function show() { $data['tasks'] = array(); $data['tasks'] = $this->Tasks_model->show_task(); $this->load->view('pages/all', $data); } 

Model:

public function show_task() { return $this->db->get('task')->result(); } 

View Page:

<?php if( isset($tasks) && ( is_array($tasks) && count($tasks)>0 ) ) { //echo"<pre>"; print_r($tasks); die(); for($i=0;$i<count($tasks);$i++) { ?> <span><?php echo $task[0]['job']; ?></span><br /> <?php } ?> <?php } else { ?> <span>No tasks records found.</span> <?php } ?>
