Here is my Model Codel
public function print_report($Patient_ID, $ID)
{
$query = $this->db->query('select a.ID, a.Description, a.Description_Group, a.Normal_Range, a.Measure_Unit,
b.Result_Value
from tbltestdefault a
inner join tblreportdetail b on a.ID = b.Test_Default_ID
where b.Patient_ID = '.$Patient_ID.' and b.Patient_Test_ID = '.$ID.'');
return $query->result_array();
}
Controller
public function print_report($ID, $Patient_ID, $Test_ID)
{
$data['patient'] = $this->Report_Model->getPatientinfo($Patient_ID);
$data['testname'] = $this->Report_Model->gettestnameonly($Test_ID);
$data['tests'] = $this->Report_Model->print_report($Patient_ID, $ID);
$this->load->view('report_view', $data);
}
and a view to display data
<table class="table table-bordered">
<thead>
<tr>
<th> <h4>Description</h4>
</th>
<th> <h4>Result</h4>
</th>
<th> <h4>Units</h4>
</th>
<th> <h4>Normal Value</h4>
</th>
</tr>
</thead>
<tbody>
<?php foreach($tests as $t): ?>
<tr>

<td><?php echo $t['Measure_Unit']; ?></td>
<td><?php echo $t['Normal_Range']; ?></td>
</tr>
<?php endforeach; ?>

man, i think you are taking this site for granted.. i already provided you the main logic.you just need to expand it depending on your additional needs.. btw here's the expanded logic
<?php
$get_title = '';
$get_subtitle = '';
foreach($tests as $t)
{
//if start of new test name
if($get_title != $t['Test_Name'])
{
echo $t['Test_Name'];
//if start of new desc group
if($get_subtitle != $t['Description_Group'])
{
echo $t['Description_Group'];
echo $t['description'];
$get_subtitle = $t['Description_Group'];
}
//if same desc with previous
elseif($get_subtitle == $t['Description_Group'])
{
echo $t['description'];
}
$get_title = $t['Test_Name'];
}
//if same title with previous
elseif($get_title == $t['Test_Name'])
{
//if start of new desc group
if($get_subtitle != $t['Description_Group'])
{
echo $t['Description_Group'];
echo $t['description'];
$get_subtitle = $t['Description_Group'];
}
//if same desc with previous
elseif($get_subtitle == $t['Description_Group'])
{
echo $t['description'];
}
}
}
add this at the last part of your sql query
ORDER BY Test_Name ASC, Description_Group ASC, Description ASC
not sure if this would work, because i haven't tried it.. hit me with some comments if something went wrong..cheers
