Visualizaçõesechoing the text message from textarea via PHP and AJAX jQuery
HTML:
<div class="mb-3">
<label for="comment" class="form-label">Comments</label>

alert(comment);
and then PHP:
echo $_POST['comment'];
echo isset($_POST['comment']);
echo trim($_POST['comment']) != '';

<div class="mb-3">
<label for="comment" class="form-label">Comments</label>
<textarea class="form-control" id="comment" name="comment" rows="3"></textarea>
</div>
id is unique in the HTML and with jquery it would be easier to target the element you want. For class we use $(.<classNAME>) while for id we use $(#<id_Name>)
Your Case, $('#comment').val()
