I am trying to display a list of comments from a MySql database in PHP.
The foreach loop works as it displays the necessary html for each comment in the database, but no actual content from the database is being pulled through.
Comment class
class Comment {
protected $_id;
protected $_user;
protected $_commentText;
protected $_dateTimePosted;
public function __construct()
{
$this->_dateTimePosted = new DateTime();
$this->_dateTimePosted->format(DATE_RFC3339);
}
public function get_id()
{
return $this->_id;
}
public function set_id($value)
{
$this->_id = $value;
}
public function get_user()
{
return $this->_user;
}
public function set_user($value)
{
$this->_user = $value;
}
public function get_commentText()
{
return $this->_commentText;
}
public function set_commentText($value)
{
$this->_commentText = $value;
}
public function get_dateTimePosted()
{
return $this->_dateTimePosted;
}
public function set_dateTimePosted($value)
{
$this->_dateTimePosted = $value;
}
}
CommentFunctions.php
include 'dbConnect.php';
class CommentFunctions {
protected $conn;
public function __construct()
{
$this->conn = dbConnect();
}
public function get_comments()
{
$sql = "SELECT * FROM comments";
$stmt = $this->conn->stmt_init();
$stmt->prepare($sql);
$stmt->execute();
$stmt->store_result();
$comments = array();
while ($row = $stmt->fetch())
{
$comment = new Comment();
$comment->set_id($row['id']);
$comment->set_user($row['user']);
$comment->set_commentText($row['comment_text']);
$comment->set_dateTimePosted($row['datetime_posted']);
$comments[] = $comment;
}
return $comments;
}
}
Index.php
<?php
include './includes/Comment.php';
include './includes/CommentFunctions.php';
$comments_func = new CommentFunctions();
$all_comments = $comments_func->get_comments();
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Comments</title>
<link rel="stylesheet" type="text/css" href="./css/Master.css" />
<link rel="stylesheet" type="text/css" href="./css/Site.css" />
</head>
<body>
<div id="Container">
<h2>Comments</h2>
<a class="reload-comments" href="/">Refresh</a>
<div id="Comments">
<?php if (!$all_comments) {
echo 'No comments yet.';
} ?>
<?php foreach ($all_comments as $c) { ?>
<div class="comment">
<input class="id" type="hidden" value="<?php echo $c->get_id(); ?>" />
<div class="author">Posted by <?php echo $c->get_user(); ?></div>
<div class="comment-text">
Posted <?php echo $c->get_dateTimePosted(); ?>
<p><?php echo $c->get_commentText(); ?></p>
</div>
</div>
<?php } ?>
</div>
<div id="AddComment">
<form name="add_comment_form" id="add_comment_form" action="index.php" method="post">
<label for="user">Your Name:</label>
<input name="user" id="user" type="text" /><br />
<label for="comment_text">Comment:</label>
<textarea name="comment_text" id="comment_text" rows="5" cols="10"></textarea><br />
<input name="submit" id="submit" type="submit" value="Submit" />
<input id="reset" type="reset" class="hidden" />
</form>
</div>
<div class="loader"></div>
<div class="response"></div>
</div>
</body>
Comments can be added, the data is stored fine in the database, and the loop runs the correct number of times, but the code such as echo $c->get_commentText(); is not displaying a value.
Appreciate any help.
