How do I assign the "active" value to a tab on the first tab in a php while loop?-CodePudding

I'm using a while loop to populate tabs with PHP. If I assign active while it's in the loop then they are all active. This much I understand. If I only want the first item / tab to have the where should the script be changed?

while($row  = $result->fetch_assoc() ) {
  $id = $row['id'];
  $in = $row['initial'];
  $name = $row['name'];     
echo "<div class=\"tab-pane fade p-2 active\" id=\"$in\" role=\"tabpanel\" aria-labelledby=\"$in-tab\">"; // make tabs

Track an indicator that you've already rendered the "first" tab. Something as simple as:

$firstTab = true;

Then within the loop, set it to true after rendering the "first" tab, conditionally including the active class:

$firstTab = true;
while($row  = $result->fetch_assoc() ) {
  $id = $row['id'];
  $in = $row['initial'];
  $name = $row['name'];     
  echo "<div class=\"tab-pane fade p-2 " . ($firstTab ? "active" : "") . "\" id=\"$in\" role=\"tabpanel\" aria-labelledby=\"$in-tab\">";
  $firstTab = false;
}

First: write HTML as HTML, not using strings.

You'll need to use a index, like:

<?php
$i = 0;

while($row  = $result->fetch_assoc() ) {
  $id = $row['id'];
  $in = $row['initial'];
  $name = $row['name'];
?>
<div  id="<?= $in ?>" role="tabpanel" aria-labelledby="<?= $in-tab ?>">
...
</div>
<?php
  $i  ;
}
?>
