Changing code to MySqli

[AAC-Bob]

I am attempting to change some php code to mysqli.

I'm not a skilled programmer and am running into some query problems.

 

Here is the Existing code;

Here is the Existing code;

<?php

$link = mysql_connect($config['DB_Host'], $config['DB_User'], $config['DB_Passwd']) or die('Cannot connect to the database');

mysql_select_db($config['DB_Name'],$link) or die('Cannot select the database');

 

parse_str(str_replace(':', '&', $_COOKIE['UserSettings']),$userInfo);

$MemberID = $userInfo["MemberID"];

 

$query = "SELECT PersonID FROM `membershipperson` where MembershipID = ".$MemberID;

$result = mysql_query($query) or die ("Errant Query: ".$query);

$record = mysql_fetch_array($result);

$personID = $record["PersonID"];

 

# additional code below

?>

New Code

<?php

include ("mySqli_conn.php");

$result = $link->query($sql)or die('Cannot select the database');

 

parse_str(str_replace(':', '&', $_COOKIE['UserSettings']),$userInfo);

$MemberID = $userInfo["MemberID"];

 

$sql = "SELECT PersonID FROM `membershipperson` where MembershipID = ".$MemberID;

 

$result = $link->query($sql)or die ("Errant Query: ".$query);

$result->fetch_array($result);

 

$personID = $record["PersonID"];

?>

 

Error

Warning: mysqli::query() [mysqli.query]: Empty query in /~/position.php on line 6

Cannot select the database

 

Thanks,

It because of this here

<?php
include ("mySqli_conn.php");
$result = $link->query($sql)or die('Cannot select the database');

What query are you trying to run here. Basically $sql is either empty or not defined. So you are getting the Empty query error message.

 

Is this for selecting the database to use? If its you tell mysqli what database to use when you connect.

$link = new mysqli('hostname', 'username', 'password', 'database name'); // object
// OR
$link = mysqli_connect('hostname', 'username', 'password', 'database name'); // procedural

I use the include ("mySqli_conn.php"); for all my php database mysqli connections.

I have 4 other pages using this common file that work just fine.

 

If this is the problem then I am confused.

The include is not the issue. Its this

$result = $link->query($sql)or die('Cannot select the database');

That is what is causing the error. Delete it.

OK I removed it and error gone, TNX,

[Ch0cu3r]

$result->fetch_array($result);

 

needs to be

 

$record = $result->fetch_array(MYSQLI_ASSOC);

 

Read the manual on mysqli fetch_array http://us2.php.net/mysqli_fetch_array

Hi Ch0cu3r,

 

I went to the link and resolved the problem. Thank you.

 

OK now one more I can't seam to solve;

 

original; while($row2 = mysql_fetch_array($results2))

 

tried; while($row2 = $result2->fetch_array())

 

 

error: Warning: mysql_fetch_array() expects parameter 1 to be resource, null given

since your error message is still for an old mysql_ function, you either didn't save the changes to the file or the error is from some other line in your code.

$result->fetch_array($result);

 

needs to be

 

$record = $result->fetch_array(MYSQLI_ASSOC);

 

Read the manual on mysqli fetch_array http://us2.php.net/mysqli_fetch_array

 

 

You could also use

 

$record = $result->fetch_assoc();
