How can I connect mssql server and get values with php - php

Question

I'm a newbie on php and I try to make a calendar for people travel information from db and want to show these info on the calendar's day so my problem is to connect MSSQL Server and take the values form db.My php pages work on localhost(wampp) and my calendar view perfectly but cannot get the value from DB.It does not give an error.But can not pull data.Could you please help me to find my fault.Thanks.
connect.php;
<?php
class DBO
{
private $server = "servername";
private $db_name = "dbname";
private $password = "pass";
private $username = "username";
private $conn;
private $database;
function Connect()
{
$this->conn = mssql_connect($this->server, $this->username, $this->password)
or die("Couldn't connect to SQL Server on " . $this->server);
$this->database = mssql_select_db($this->db_name, $this->conn)
or die("Couldn't open database " . $this->db_name);
}
function RunSql($sqlQuery)
{
return mssql_query($sqlQuery);
}
}
?>
query code;
<?php
include_once("db_connect.php");
$DBO = new DBO();
$DBO->Connect();
$query = "SELECT ID, TYPE, STARTDATE, ENDDATE FROM TABLENAME";
$query_results = $DBO->RunSql($query)
or die('Error in $query_menu. Error code :' . mssql_get_last_message() );
$calendar = array();
while( $results = mssql_fetch_assoc($query_menu_results) )
{
$calendar[] = array('ID' =>$rows['ID'],'TYPE' => $rows['TYPE'],'url' => "#","class" =>'event-important','start' => "$start",'end' => "$end");
}
$calendarData = array(
"success" => 1,
"result"=>$calendar);
echo json_encode($calendarData);
exit;
?>
<?php

I believe you're issue is from executing the SQL via...
$query_results = $DBO->RunSql($query)
...but using it via...
while( $results = mssql_fetch_assoc($query_menu_results) )
Basically, $query_results becomes $query_menu_results.
I use a variant of this to test MsSQL connectivity:
<?php
// connect to the server
$dbconn = mssql_connect('SEVER_NAME_OR_IP', 'MsSQL-User', 'MsSQL-User-Password');
if (!$dbconn) {
$message='unable to connect to the database: ' . mssql_get_last_message();
die($message);
}
// select the database
if (!mssql_select_db('DATABASE_NAME', $dbconn)) {
die('Unable to select the database!');
}
// execute a query. NOTE: Never use string concatenation in SQL statements. EVER!!!
$sql = "select * from information_schema.tables;";
$query = mssql_query($sql, $dbconn);
// consume the results
echo "<table border='1'><tr><th>Column A</th><th>Column B</th></tr>";
while ($row = mssql_fetch_row($query)) {
echo "<tr><td>";
echo $row[0];
echo "</td><td>";
echo $row[1];
echo "</td></tr>";
}
echo "</table>";
// clean up
mssql_free_result($query);
mssql_close($dbconn);
?>
SECURITY NOTE: Last I check, The mssql* doesn't support prepared statements. Please see PDO or sqlsrv*. This Question has good info on MsSQL prepared statements.

Solution:
I've reproduced your code and I've found these errors:
include_once("db_connect.php"); must be include_once("connect.php");
while ($results = mssql_fetch_assoc($query_menu_results)) { must be while ($results = mssql_fetch_assoc($query_results)) {
'ID' =>$rows['ID'], must be 'ID' => $results['ID'],
'TYPE' => $rows['TYPE'], must be 'TYPE' => $results['TYPE'],
missing $start and $end variables;
Working example:
Example is based on your code. I've left your erros in comment. Table definition is just to make working query.
Database:
CREATE TABLE [dbo].[TABLENAME] (
[ID] [numeric](10, 0) NULL,
[TYPE] [numeric](10, 0) NULL,
[STARTDATE] datetime NULL,
[ENDDATE] datetime NULL
) ON [PRIMARY]
INSERT [TABLENAME] (ID, TYPE, STARTDATE, ENDDATE)
VALUES (1, 1, CURRENT_TIMESTAMP, CURRENT_TIMESTAMP)
INSERT [TABLENAME] (ID, TYPE, STARTDATE, ENDDATE)
VALUES (1, 1, CURRENT_TIMESTAMP, CURRENT_TIMESTAMP)
SELECT ID, TYPE, STARTDATE, ENDDATE
FROM [TABLENAME]
connect.php
<?php
class DBO {
private $server = "servername";
private $db_name = "dbname";
private $password = "pass";
private $username = "username";
private $conn;
private $database;
function Connect() {
$this->conn =
mssql_connect($this->server, $this->username, $this->password) or
die("Couldn't connect to SQL Server on " . $this->server);
$this->database =
mssql_select_db($this->db_name, $this->conn) or
die("Couldn't open database " . $this->db_name);
}
function RunSql($sqlQuery) {
return mssql_query($sqlQuery);
}
}
?>
query.php
<?php
//include_once("db_connect.php");
include_once("connect.php");
$DBO = new DBO();
$DBO->Connect();
$query = "SELECT ID, TYPE, STARTDATE, ENDDATE FROM [TABLENAME]";
$query_results =
$DBO->RunSql($query)
or die('Error in $query_menu. Error code :' . mssql_get_last_message() );
$calendar = array();
//while ($results = mssql_fetch_assoc($query_menu_results)) {
while ($results = mssql_fetch_assoc($query_results)) {
$calendar[] = array(
//'ID' =>$rows['ID'],
'ID' => $results['ID'],
//'TYPE' => $rows['TYPE'],
'TYPE' => $results['TYPE'],
'url' => "#",
"class" => 'event-important',
//'start' => "$start",
//'end' => "$end"
);
}
$calendarData = array(
"success" => 1,
"result"=>$calendar
);
echo json_encode($calendarData);
exit;
?>
Output:
{
"success":1,
"result":[
{"ID":"1","TYPE":"1","url":"#","class":"event-important"},
{"ID":"1","TYPE":"1","url":"#","class":"event-important"}
]
}
