PHP not inserting data into MySQL but not showing error - php

Question

I am trying to input data into a MySQL Database using PHP and a HTML Form but the data isn't saved into the database even though it shows that it has. Please show me how to ensure the form entries save to the database.
HTML
<form action="newproduct.php" method="post">
<table>
<tr>
<td>Username</td>
<td><input name="user" type="text"></td>
</tr> ...
<button type="submit">Go</button>
</form>
PHP
<?php
$servername = "localhost";
$username = $_POST["user"];
$password = $_POST["pass"];
$dbname = "bakefree_products";
$conn = mysqli_connect($servername, $username, $password, $dbname);
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$sql = "INSERT INTO ".$_POST["range"]." (productname, image, frompricesize, paypalcode, productdesc, allergystandard, allergyglutenfree, allergyvegan, allergygfvegan)
VALUES ('".$_POST["productname"]."', '".$_POST["image"]."', '".$_POST["frompricesize"]."', '".$_POST["paypalcode"]."', '".$_POST["productdesc"]."', '".$_POST["allergystandard"]."', '".$_POST["allergyglutenfree"]."', '".$_POST["allergyvegan"]."', '".$_POST["allergygfvegan"]."')";
if (mysqli_query($conn, $sql)) {
echo "New product created successfully.";
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
//show new number of products
$sql = "SELECT * FROM".$_POST["range"];
$result = $conn->query($sql);
if ($result->num_rows > 0) {echo "There are ".$result->num_rows ." products.";
} else {
echo "<br><br>There are no products in ".$_POST["range"];
}
mysqli_close($conn);
?>
RESULT
New product created successfully.
There are no products in TEST

Actually insertion should be working fine but you need to check the syntax of the select query here,
//show new number of products
$sql = "SELECT * FROM ".$_POST["range"]; // Added a space after `FROM`
And it should fetch data properly and show you the string, There are X products.
