Issue updating a record with SQL / PHP - php

Question

I am very new to PHP. Apologies if this is an elementary question.
I am trying to update a record using PHP / SQL. I have googled this error, but am unable to determine the problem out of the context of my code:
An error occured: SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens
Here is my function:
function updateTeam($val) {
global $server, $db, $dbUser, $dbKey, $message;
try {
$conn = new PDO("mysql:host=" . $server . ";dbname=" . $db, $dbUser, $dbKey);
$conn -> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = $conn -> prepare("UPDATE Team SET teamName=:teamName, teamLogo=:teamLogo, WHERE teamID=" . $val);
$sql -> bindValue(":teamID", $_POST["teamID"]);
$sql -> bindValue(":teamName", $_POST["teamName"]);
$sql -> bindValue(":teamLogo", $_POST["teamLogo"]);
$result = $sql -> execute();
if ($result) {
$message = "Customer record was updated";
} else {
$message = "The Customer record was not updated";
}
}
catch(PDOException $e) {
echo "<div class='notification container'><p>An error occured: " . $e -> getMessage() . "</p></div>";
}
$conn = null;
}
if (isset($_POST["updateTeam"])) {
updateTeam($_POST["teamID"]);
}
and here is my markup:
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<label>Team ID</label>
<input type="text" name="teamID" placeholder="9" value="<?php echo $teamID; ?>">
<label>Team name</label>
<input type="text" name="teamName" placeholder="Watson's Bay Warriors" value="<?php echo $teamName; ?>">
<label>Team logo (optional)</label>
<input type="text" name="teamLogo" placeholder="Blob" value="<?php echo $teamLogo; ?>">
<input type="submit" name="insertTeam" value="Add">
<input type="submit" name="getTeam" value="Get">
<input type="submit" name="updateTeam" value="Update">
<input type="submit" name="deleteTeam" value="Delete">
</form>
I have similar functions in place that allow me to add, get and delete and have no issues.

Answer 1

"UPDATE Team SET teamName=:teamName, teamLogo=:teamLogo WHERE teamID=:teamID")
Remove the comma before the WHERE clause

Answer 2

In your code:
$sql = $conn -> prepare("UPDATE Team SET teamName=:teamName, teamLogo=:teamLogo, WHERE teamID=" . $val);
$sql -> bindValue(":teamID", $_POST["teamID"]);
$sql -> bindValue(":teamName", $_POST["teamName"]);
$sql -> bindValue(":teamLogo", $_POST["teamLogo"]);
Why is teamID =" .$val but you bind the param teamID to a post value? Could that be the error?
