问题
Hi guys i am trying to display the first td values as static so i have keep those values in one array and i try to increase the values and try to display but when i get it is displaying depending on foreach values if i have one record in foreach it is displaying one value and if i have 2 records it is displaying 2 values.
But i want to display all td value if i have values in foreach or not also.
Here is my code:
<tbody>
<?php
$arr = array(0=>'On Hold',1=>'Asset Incomplete',2=>'SME Discussion',3=>'a',4=>'b',5=>'c',6=>'d',7=>'e',8=>'f',9=>'g',10=>'h');
$i = 0;
foreach($getCourse as $report)
$status= $report->status;
{
?>
<tr>
<td><?php echo $arr[$i]; ?>
<?php $i++; ?></td>
<td><?php
if($status==1)
{
echo "On Hold";
}
elseif($status==2)
{
echo "Asset Incomplete";
}
elseif($status==3)
{
echo "Yet to Start";
}
elseif($status==4)
{
echo "SME Discussion";
}
elseif($status==5)
{
echo "Development";
}
elseif($status==6)
{
echo "PB Review";
}
elseif($status==7)
{
echo "PB Fixes";
}
elseif($status==8)
{
echo "PB2 Review";
}
elseif($status==9)
{
echo "PB2 Fixes";
}
elseif($status==10)
{
echo "Alpha Development";
}
elseif($status==11)
{
echo "Alpha Review";
}
elseif($status==12)
{
echo "Alpha Fixes";
}
elseif($status==13)
{
echo "Beta Review";
}
elseif($status==14)
{
echo "Beta Fixes";
}
elseif($status==15)
{
echo "Gamma";
}
?></td>
<td><?php echo $report->coursename; ?></td>
<td><?php echo $report->statuscount;?></td>
<td></td>
</tr>
<?php
}
?>
</tbody>
Here is my controller:
public function index()
{
if ($this->session->userdata('is_logged')) {
$data['getCourse']=$this->Report_model->getTopicReports();
$this->load->view('template/header');
$this->load->view('reports/report',$data);
$this->load->view('template/footer');
}
else {
redirect("Login");
}
}
Here is my model:
public function getTopicReports()
{
$this->db->select('count(t.status) as statuscount,t.topicName as topicname,c.coursename,t.status')
->from('topics t')
->join('course c', 't.courseId = c.id')
->where('t.courseid',1)
->where('t.status',5);
$query = $this->db->get();
return $query->result();
}
This is how i want to display here is my referrence image:
Can anyone help me how to do that thanks in advance.

FINAL UPDATED & WORKING VERSION
For me this was tricky. This turned out to be what I felt to be a awkward indexing issue.
The problem is that your data is not optimized very well to accommodate the task you are asking for. You have to make odd comparisons as you traverse the table. I was able to get it accomplished.
I would actually be very interested in seeing a more refined approach. But until that happens this code will dynamically generate a table that matches the output of the sample pictures that you posted in your question.
I have tested this code with some sample data that matches the array structure that you posted in your comments.
Here is the code:
//Create an array with your status values.
$rowName = array(
'On Hold',
'Asset Incomplete',
'Yet to Start',
'SME Discussion',
'Development',
'PB Review',
'PB Fixes',
'PB2 Review',
'PB2 Fixes',
'Alpha Development',
'Alpha Review',
'Alpha Fixes',
'Beta Review',
'Beta Fixes',
'Gamma'
);
//Generate a list of class names and get rid of any duplicates.
foreach($getCourse as $report){
$courseNames[] = $report->coursename;
}
$courseNames = array_unique($courseNames);
//Create the header.
echo
'<table>
<thead>
<tr>
<th>#</th>';
foreach($courseNames as $course){
echo '<th>' . $course . '</td>';
}
echo
'<th>Total</th>
</tr>
</thead>
<tbody>';
//Iterate across the array(list) of status values.
for($i = 0; $i < count($rowName); $i++){
echo
'<tr>';
echo '<td>' . $rowName[$i] . '</td>';
//Iterate through all combinations of class names and status values.
for($j = 0; $j < count($courseNames); $j++){
//Set flags and intial values.
$found = FALSE;
$total = 0;
$value = NULL;
for($k = 0; $k < count($getCourse); $k++){
//***Note - The ""$getCourse[$k]->status - 1" is because the status values in your data do not appear
//to start with an index of 0. Had to adjust for that.
//Sum up all the values for matching status values.
if(($getCourse[$k]->status - 1) == $i){
$total += $getCourse[$k]->statuscount;
}
//Here we are checking that status row and the status value match and that the class names match.
//If they do we set some values and generate a table cell value.
if(($getCourse[$k]->status - 1) == $i && $courseNames[$j] == $getCourse[$k]->coursename){
//Set flags and values for later.
$found = TRUE;
$value = $k;
}
}
//Use flags and values to generate your data onto the table.
if($found){
echo '<td>' . $getCourse[$value]->statuscount . '</td>';
}else{
echo '<td>' . '0' . '</td>';
}
}
echo '<td>' . $total . '</td>';
echo
'</tr>';
}
echo '</tbody>
</table>';

Try this. I am storing course status in $used_status then displaying the remaining status which are not displayed in foreach.
$arr = array ( '1' =>'On Hold', '2' => 'Asset Incomplete', '3' => 'SME Discussion', '4' => 'a', '5' => 'b', '6' => 'c', '7' =>'d', '8' => 'e', '9' => 'f', '10' => 'g', '11' => 'h' );
$used_status = array();
foreach($getCourse as $report) { ?>
<tr>
<td>
<?php $course_status = isset($arr[$report->status]) ? $arr[$report->status] : "-";
echo $course_status;
$used_status[] = $course_status; ?>
</td>
<td>
<?php echo $report->coursename; ?>
</td>
<td>
<?php echo $report->statuscount; ?>
</td>
</tr>
<?php }
foreach($arr as $status) {
if(!in_array($status, $used_status)) { ?>
<tr>
<td>
<?php echo $status; ?>
</td>
<td>
<?php echo "-"; ?>
</td>
<td>
<?php echo "-"; ?>
</td>
</tr>
<?php }
} ?>
