QLSTATE[HY093]: Invalid parameter number: parameter was not defined - php

Question

I am having trouble of finding why my code is not working . I tried to look up on the internet but I can't seem to find the error.
Here's my function
public function AddNews($newsDate,$title,$content){
try{
$stmt = $this->db->prepare("INSERT INTO news(newsDate,title,content) VALUES (:newsDate,:$title,:$content)");
$stmt->bindParam(":newsDate", $newsDate);
$stmt->bindParam(":title", $title);
$stmt->bindParam(":content", $content);
$stmt->execute();
return $stmt;
}catch(PDOException $ex){
echo $ex->getMessage();
}
}
and the form action
/*---------DEVELOPMENT-----------*/
require_once '/database/database.php';
/*---------ENVIRONMENT-----------*/
// require_once 'database/database.php';
if(isset($_POST['btn-news-submit'])){
$newsDate = trim($_POST['newsDate']);
$title = trim($_POST['bodyContent']);
$content = trim($_POST['newsContent']);
if($user->AddNews($newsDate,$title,$content)){
header("Location: admin-index.php?successfully-uploaded");
}
}
and lastly my html form
<div class="news">
<form action = "upload-news" method="POST" enctype="multipart/form-data">
<div class="form-group">
<input type="hidden" name="newsDate" id="newsDate" value="<?php echo date('Y-m-d H:i:s'); ?>" readonly="readonly">
<label for="bodyContent"><b>Title</b></label>
<textarea class="form-control" rows="1" id="bodyContent" name="bodyContent"></textarea>
<br>
<label for="exampleFormControlFile1">Content of News</label>
<textarea class="form-control" rows="5" id="newsContent" name="newsContent"></textarea>
<br />
<br>
<div class="btn-news">
<button type="submit" name="btn-news-submit" class="btn btn-primary">Post</button>
</div>
</div>
</form>
</div>
Could someone please point out where is the error here . It says
SQLSTATE[HY093]: Invalid parameter number: parameter was not defined
But I checked several times and all my bindParam are matched

Answer 1

Don't use dollar signs in your bind handles here:
"INSERT INTO news(newsDate,title,content) VALUES (:newsDate,:$title,:$content)"
^ ^
Just use plain strings like this:
"INSERT INTO news(newsDate,title,content) VALUES (:newsDate,:title,:content)"
