I am trying to get some simple information from a DB table and post it on a HTML page. It's seems pretty simple and straight forward, I get no errors which means I connect to the DB and the table. I have all the data already there (entered manually).
I am assuming that it is in the way I call the column names to make the query.
<?php
require_once("settings.php");
//Open Connection
$conn = @mysqli_connect("$host","$user","$pswd")
or die ('Failed To Connect to Server');
@mysqli_select_db("$conn", "$dbnm")
or die ('Database Not Available');
//Set up SQL string and excecute
$car_id = mysqli_escape_string($_GET['car_id']);
$make = mysqli_escape_string($_GET['make']);
$model = mysqli_escape_string($_GET['model']);
$price = mysqli_escape_string($_GET['price']);
$query = "SELECT car_id, make, model, price FROM cars";
$results = mysqli_query($conn, $query);
echo "<table width ='100%' border='1'>
<tr>
<th>car_id</th>
<th>make</th>
<th>model</th>
<th>price</th>
</tr>";
// $row = mysqli_fetch_row($query);
while ($row = mysqli_fetch_array($results)) {
echo "<tr>";
echo "<td>" . $row['car_id'] . "</td>";
echo "<td>" . $row['make'] . "</td>";
echo "<td>" . $row['model'] . "</td>";
echo "<td>" . $row['price'] . "</td>";
echo "</tr>";
// $row = mysqli_fetch_row($query);
}
echo "</table>";
//Close Connection
mysqli_free_result($results);
mysqli_close($conn);
?>
settings.php holds all the connection info and it all checks out. Do I even need the ($_GET['car_id']), etc? Can I just call them by the field name?
The answer is gonna be so obvious...
I get no errors which means I connect to the DB and the table
It does not mean that.
mysqli_select_db("$conn", "$dbnm") // That `$conn` should not be inside those quotes.
Should be
mysqli_select_db($conn, $dbnm); // that $conn has to be a MySQLi link identifier, not an interpolated one.
Also remove all the @ and do some error checking as to what those functions return.
Please change the following line as below.
$conn = @mysqli_connect("$host","$user","$pswd")
to
$conn = mysqli_connect($host,$user,$pswd)
And
@mysqli_select_db("$conn", "$dbnm")
to
mysqli_select_db($conn, $dbnm)
