I have written a page to display vehicles for sale with a picture, year, make, model and price of vehicle.  There is no syntax errors in the code and when I run the code It displays nothing.  My code is listed below.  Please help.

<?php
    include_once('dbconnect.php');

$q = "SELECT * FROM vehicles";
$r = mysqli_query($q);
    
echo "<table align='center' width='990' class='table'>
<tr>
<th>Picture</th>
<th>Year</th>
<th>Make</th>
<th>Model</th>
<th>Price</th>
</tr>";
while($row = mysqli_fetch_array($r)){

echo "<tr>";
echo "<td width='203'>";
echo "<img src='data:image/jpeg;base64,".base64_encode($row['image'])."'>";
echo "</td>";
echo "<td>" .$row['year']. "</td>";
echo "<td>" .$row['make']. "</td>";
echo "<td>" .$row['model']. "</td>";
echo "<td>" .$row['price']. "</td>";
echo "</tr>";
echo "</table>";
}
?>
</body>
</html>
 

Code from dbconnect.php:

 

<?php
  mysqli_connect("localhost", "takisis", "zifnab#666") or die(mysqli_error());
  mysqli_select_db("ezwayautos") or die(mysqli_error());
?>

do you have php's error_reporting set to E_ALL and display_errors set to ON so that php would help you by reporting and displaying all the errors it detects?

 

next, you cannot use mysqli_error() to display mysqli_connect() errors, because msyqli_error(...) requires the connection as a parameter. you must use mysqli_connect_error() to display mysqli_connect() errors.

 

lastly, you should always test if your database queries ran without any errors (display a user error message and display/log for development/live server the actual error information) and for queries that may match zero rows, test if the query matched any row and output a user message if it doesn't (sorry, no data was found.)

Ok I now have the data displaying from the database.  Thanks for the help.  I need to get it to format so that one listing is right below the last in my table.  Here is the new code so that you can see what is changed.  I will also attach the file so that you can run it and give me suggestions.
