I am trying to get php to simplify my database connections so that I can modify one area of the code and effect the entire program. Here is what I have:
PAGE: rdpa.php (A modules page
/**************************/
/* Create System Settings */
/**************************/
/* Database Connection Settings */
$_SESSION['servername'] = "localhost";
$_SESSION['mysql_username'] = "username";
$_SESSION['mysql_password'] = "password";
$_SESSION['dbname'] = "mydb";
//Turn on Error Report. True = On / False = Off
//ErrorReporting(false);
//Display Error.kfkg
function ErrorReporting($ErrOn){
if ($ErrOn == true) {
//Show Error
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);
}
}
/**************************************
Open Database Connection Function.
***************************************/
class db_class {
function db_conn() {
global $conn;
global $mysqli;
$conn = new mysqli($_SESSION['servername'], $_SESSION['mysql_username'], $_SESSION['mysql_password'], $_SESSION['dbname']);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
// Test if connection succeeded
if(mysqli_connect_errno()) {
die("Database connection failed: " .
mysqli_connect_error() .
" (" . mysqli_connect_errno() . ")"
);
}
//return db_conn;
}
}
PAGE: testdb3.php
<?php
//Included file.
include 'modules/rdpa.php';
error_reporting(-1);
ini_set('display_errors', 'On');
//Access our class.
$db_Class = new db_Class;
$conn = ($db_Class->db_conn());
//connect to the database.
$sql = "SELECT id, region FROM tbl_region;";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo '<td width="1"><label for="delete">
<input type="radio" name="region" id="region" value="'.$row["id"].'">
</label></td>';
echo '<td align="left" valign="top"><p>'.$row["region"].'</p></td></tr>';
}
}
?>
When I run testdb3.php I get the following error:
Fatal error: Call to a member function query() on a non-object in C:\websitesdpa\testdb3.php on line 15
This is Line 15:
//connect to the database.
$result = $conn->query($sql);
Can some please tell me what I am doing wrong here?
