Accessing Array Element in php codeigniter does not work [duplicate]

Question

Accessing array element "id" in codeigniter does not work. Cant find a possible cause to fail. If anyone can show the proper way to do that will be helpful,

My View

<form name ="userinput" onsubmit="return test()" action="<?php echo base_url(); ?>index.php/patient/saveNewExaminationChart/<?php echo $pd['id']; ?>" method="post">

<?php echo $pd['id']; ?> For this part i want to get the id number passed by controller to view.

My Controller

public function editPeriodicalDetails(){

        $pid = $this->uri->segment(3);
        $this->load->model('patient_model');
        $patient['pd'] = $this->patient_model->getPeriodicalChart($pid);


        $this->load->helper('url');
        $this->load->view('Header');
        $this->load->view('Patient/editPeriodicalExam',$patient);
        $this->load->view('Footer');
}

My Model

public function getPeriodicalChart($id){
        $this->load->database();
        $this->db->select('*');
        $this->db->from('periodical_examination a');
        $this->db->join('patient p','p.id = a.pid');
        $this->db->where('a.pid',$id);

        $query = $this->db->get();
        return $query->result();

    }

U have a lot of solution now u can test them and mark as accepted otherwise people think its open question. — devpro

In model

return $query->result_array();

In Controller

$result= $this->patient_model->getPeriodicalChart($pid);
$patient = $result[0]['pd']; # zero indexed array pointer

result() is recursive in that it returns an std class object where as result_array() just returns a pure array, so result_array() would be choice regarding performance. There is very little difference in speed though.anyone with basic knowledge in php will find easy to read the code

Instead of this lines

$query = $this->db->get();
 return $query->result();

(Just use this its really easy to understand)

return $this->db->get()->result_array();

It should be an object. Try this

<?php echo $pd->id; ?>

if there could be more that one result set, then try this

<?php echo $pd[0]->id; ?>

$query->result();

is an Object not an array..to return a Array you should use

$query->result_array();

Here you used return $query->result(); in your Model and sent the all table to the view through Controller. That's great job. All are fine. Now you just use the below code in your view page to echo the id.

view (editPeriodicalExam)

<?php
 foreach($pd as $item){
    echo $item['id'];
 } 
?>
