Hello.
I have two cycles in PHP, that I needed converting to smarty structure. Down includes PHP code.

Code:

 
  $query = mysqli_query($cnn, "SELECT *, COUNT(*) AS ph FROM course INNER JOIN completed_course ON course.id = completed_course.id_course  GROUP BY course.id");
 
  while ($row = mysqli_fetch_array($query)){ ?>
       <tr> <td> <?php echo  $row['id']; ?></td><td> <?php echo  $row['nazev']; ?>  </td><td> <?php echo  $row['ph']; ?>  </td> <td>
<?php
$Number_of_graduates = mysqli_query($cnn, "SELECT COUNT(*) AS abs FROM  participant where id_completed_course = $row[id]");
while ($rAbs = mysqli_fetch_array($Number_of_graduates)){
        echo $rAbs['abs'];
     }  ?>
    </td>
<?php }



Please with help. Thank you.

Here is a start. You can finish the template.

Code:
$query = mysqli_query($cnn, "SELECT *, COUNT(*) AS ph FROM course INNER JOIN completed_course ON course.id = completed_course.id_course  GROUP BY course.id");
 
  while ($row = mysqli_fetch_array($query)) {
      $rows[] = $row;
  }
       
$smarty->assign('rows', $rows);
$smarty->display('index.tpl');


Code:
{foreach $rows as $row}
    <tr><td>{$row.id}</td></tr>
{/foreach}

I didn't see the 2nd query in there. It is just grabbing the count(*), so no need to while() loop it. Something like:

Code:
$query = mysqli_query($cnn, "SELECT *, COUNT(*) AS ph FROM course INNER JOIN completed_course ON course.id = completed_course.id_course  GROUP BY course.id");
 
  while ($row = mysqli_fetch_array($query)) {
       
    $Number_of_graduates = mysqli_query($cnn, "SELECT COUNT(*) AS abs FROM  participant where id_completed_course = $row[id]");
    $abs = mysqli_fetch_array($Number_of_graduates));
    $row['abs']= $abs[0];
    $rows[] = $row;
}
$smarty->assign('rows',$rows);
$smarty->display('index.tpl');


index.tpl:

Code:
{foreach $rows as $row}
    {$row.id}
    {$row.abs}
{/foreach}

index.tpl:

Code:
{foreach $rows as $row}
    {$row.id}
    {$row.abs}
{/foreach}


I have rather help, as the value of ID from the first sql query to get the second query as WHERE
