Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in .../functions.php on line 60
Here is functions.php:
<?php
function inline($symbol){
GLOBAL $dbc;
require_once ('mysqli_connect.php');
$inline_display = "error";
$q = "SELECT rating WHERE symbol = '$symbol'";
$r = mysqli_query($dbc, $q);
while ($row = mysqli_fetch_array($r)){
$rating = $row['rating'];
}
if($rating == 1)
$inline_display = "$symbol - <font color=\"#ff0000\"><b>Avoid</b></font>";
if($rating == 2)
$inline_display = "$symbol - <font color=\"#990000\"><b>Risky</b></font>";
if($rating == 3)
$inline_display = "$symbol - <font color=\"#666666\"><b>Neutral</b></font>";
if($rating == 4)
$inline_display = "$symbol - <font color=\"#006600\"><b>Compelling Buy</b></font>";
if($rating == 5)
$inline_display = "$symbol - <font color=\"#ff6600\"><b>Top Pick</b></font>";
return $inline_display;
}
?>
This is the page that calls the function:
<html>
<body>
<?php
//require_once ('mysqli_connect.php');
include ('functions.php');
$symbol = "XOM";
echo inline($symbol);
?>
</body>
</html>
And here is mysqli_connect.php:
<?php
// Set the database access information as constants:
DEFINE ('DB_USER', 'user');
DEFINE ('DB_PASSWORD', 'pass');
DEFINE ('DB_HOST', 'host');
DEFINE ('DB_NAME', 'db');
// Make the connection:
$dbc = @mysqli_connect (DB_HOST, DB_USER, DB_PASSWORD, DB_NAME) OR die ('Could not connect to MySQL: ' . mysqli_connect_error() );
// Set the encoding...
mysqli_set_charset($dbc, 'utf8');
// Use this next option if your system doesn't support mysqli_set_charset().
//mysqli_query($dbc, 'SET NAMES utf8');
?>
I think my problem has something to do with making $dbc a global variable, but I haven't been able to resolve the issue. What am I doing wrong?
