PHP - Old Code Mysql To Mysqli

Hi, I am trying to convert the register & login script from mysql to mysqli. I have converted the easy parts and have the connection to the database, but the following functions all need changing and I can't work out the correct solution mainly due to the deprecation of mysql_result()

The code that needs updating is
 

<?php
function user_count() {
	return mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `active` = 1"), 0);
}

function users_online() {
	return mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `logged_in` = 1"), 0);
}

function change_profile_image($user_id, $file_temp, $file_extn) {
	$file_path = 'images/profile/' . substr(md5(time()), 0, 10) . '.' . $file_extn;
	move_uploaded_file($file_temp, $file_path);
	mysql_query("UPDATE `users` SET `profile` = '" . mysql_real_escape_string($file_path) . "' WHERE `user_id` = " . (int)$user_id);
}

function has_access($user_id, $type) {
	$user_id 	= (int)$user_id;
	$type 		= (int)$type;
	
	return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `user_id` = $user_id AND `type` = $type"), 0) == 1) ? true : false;
}

function activate($email, $email_code) {
	$email 		= mysql_real_escape_string($email);
	$email_code = mysql_real_escape_string($email_code);
	
	if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `active` = 0"), 0) == 1) {
		mysql_query("UPDATE `users` SET `active` = 1 WHERE `email` = '$email'");
		return true;
	} else {
		return false;
	}
}

function user_exists($username) {
	$username = sanitize($username);
	$query = mysql_query("SELECT COUNT('user_id') FROM `users` WHERE `username` = '$username'");
	return (mysql_result($query, 0) == 1) ? true : false;
}

function email_exists($email) {
	$email = sanitize($email);
	return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email'"), 0) == 1) ? true : false;
}

function user_id_from_username($username) {
	$username = sanitize($username);
	return mysql_result(mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '$username'"), 0, 'user_id');
}

function user_id_from_email($email) {
	$email = sanitize($email);
	return mysql_result(mysql_query("SELECT `user_id` FROM `users` WHERE `email` = '$email'"), 0, 'user_id');
}

function login($username, $password) {
	$user_id = user_id_from_username($username);
	
	mysql_query("UPDATE `users` SET `logged_in` = 1 WHERE `user_id` = $user_id");

	$username = sanitize($username);
	$password = md5($password);
	
	return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `username` = '$username' AND `password` = '$password'"), 0) == 1) ? $user_id : false;
}

?>

And here is what the converter gave me:

function user_count() {
return mysql_result(mysqli_query($GLOBALS["___mysqli_ston"], "SELECT COUNT(`user_id`) FROM `users` WHERE `active` = 1"), 0);
}

function users_online() {
return mysql_result(mysqli_query($GLOBALS["___mysqli_ston"], "SELECT COUNT(`user_id`) FROM `users` WHERE `logged_in` = 1"), 0);
}

function change_profile_image($user_id, $file_temp, $file_extn) {
    $file_path = 'images/profile/' . substr(md5(time()), 0, 10) . '.' . $file_extn;
    move_uploaded_file($file_temp, $file_path);
    mysql_query("UPDATE `users` SET `profile` = '" . mysql_real_escape_string($file_path) . "' WHERE `user_id` = " . (int)$user_id);
}

function has_access($user_id, $type) {
    $user_id     = (int)$user_id;
    $type         = (int)$type;
    
    return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `user_id` = $user_id AND `type` = $type"), 0) == 1) ? true : false;
}

function activate($email, $email_code) {
    $email         = mysql_real_escape_string($email);
    $email_code = mysql_real_escape_string($email_code);
    
    if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `active` = 0"), 0) == 1) {
        mysql_query("UPDATE `users` SET `active` = 1 WHERE `email` = '$email'");
        return true;
    } else {
        return false;
    }
}

function user_exists($username) {
    $username = sanitize($username);
    $query = mysql_query("SELECT COUNT('user_id') FROM `users` WHERE `username` = '$username'");
    return (mysql_result($query, 0) == 1) ? true : false;
}

function email_exists($email) {
    $email = sanitize($email);
    return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email'"), 0) == 1) ? true : false;
}

function user_id_from_username($username) {
    $username = sanitize($username);
    return mysql_result(mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '$username'"), 0, 'user_id');
}

function user_id_from_email($email) {
    $email = sanitize($email);
    return mysql_result(mysql_query("SELECT `user_id` FROM `users` WHERE `email` = '$email'"), 0, 'user_id');
}

function login($username, $password) {
    $user_id = user_id_from_username($username);
    
    mysql_query("UPDATE `users` SET `logged_in` = 1 WHERE `user_id` = $user_id");

    $username = sanitize($username);
    $password = md5($password);
    
    return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `username` = '$username' AND `password` = '$password'"), 0) == 1) ? $user_id : false;
}

?>

Please could someone point me in the right direction here?     Also my site works perfectly well with MySQL, do I have to convert it to MySQLi?   Many Thanks   Paul If anyone knows how to solve this, it would be much appreciated. I already have a website template and would prefer to continue with mysqli instead of PDO.

Many Thanks

Paul

I'm a beginner here and i am learning the basic in converting from MySQL to MySQLi. I am currently working on this registration page which I would want to convert to MySQLi. Please advise me how to modify this script, I would prefer the procedural style. The MySQLi coding is not working because it would notg insert into the database like the MySQL coding would, would appreciate if your can help me. MYSQL

I have a prepared statement class for MYSQL, since in PHP 5 this is now changing to mysqli; I'm looking for some help in changing the code from my existing class to the new mysqli.   I have done some research online about changing from mysql to mysqli but the changes I made seems to only cause issues with connecting to the database.   After many hours of changing the existing file using the research online, I've decided to start again and ask others if they would be ever so kind to help this noob out and point out which parts of the script needs to be changed.    Thank you for reading.

how i can make a insert using this fuctions I m learning php, as using this functions (mysqli abstract) but after update wont work any more.

/** insert data array */
public function insert(array $arr)
{

if ($arr)
{
$q = $this->make_insert_query($arr);
$return = $this->modifying_query($q);
$this->autoreset();
return $return;
}
else
{
$this->autoreset();
return false;
}
}

complement

{
$data = array($data);
}
$keys = array();
$values = array();
$keys_set = false;

Hi there,   I'm new to all this so I've been following instructions from various sites and books.  So far I have installed Apache, PHP and mysql, however when I browse to localhost/test.php (created to view phpinfo() through the browser) i can't see mysql or mysqli only the mysqlnd.   Here is an overview of software I've installed, OS and things I've added so far;   OS ver Windows7 Professional 32-bit VM

I have several registration systems that were designed some time ago running mysql. How long do I have until I have to competely move to mysqli? I am working on recoding them, but it is taking some time. Does anyone know when it will become an issue?

How can I make sure that when I submit an new form and new ID (record) is created it is always 4-Digits. record 14 = 0014, record 225 = 0225.
Thanks

At this time i am building an email generation report program.  I have everything working for the first and second report.  But when i try to update and get the 3 run of emails it doesnt update the previous one.  below you will find the code that i have been working on and i have everything working except for the update to run every single time.

Code: [Select]
$con = mysql_connect("test","test","test");

// $con = mysql_connect("localhost","root","");

if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("test", $con);
// mysql_select_db("test", $con);

$id = $_POST['id'];
$demo = $_POST['demo'];

$limit = $row["unique_recp"];

}

$res = mysql_query("SELECT emails FROM email_list WHERE custid = '$id' and demo = 'N' LIMIT ".$limit." ");

while ($row = mysql_fetch_array($res))
{
echo "<div id=\"left\">".$row['emails']."</div><div id=\"clr\"></div>";
}
mysql_query($res);

$res2 = "update email_list set demo = 'Y' WHERE custid = '$id' LIMIT ".$limit."";

mysql_query($res2);

mysql_close($con);

I have put in test for the actual data.

Let me know if you can figure out what is going on?  If you need to see the enter code i can send it.

I'm trying to use php code that is stored in the sql database, but It doesn't seem to be executing the code.  when I see the page source, its there but the server is not executing the command how do I accomplish this.

Here is a simple code snippet to show what I am trying to do.

$result = mysql_query("select * from data");
$row = mysql_fetch_array($result);
echo $row['code'];

In the code field in data table this is whats there.
<?php echo "testing."; ?>

Could someone please help me out here? I've been using the code below in some of my WordPress pages, but I've looked at it so long ago that I honestly can't remember how to debug it - go figure... The only thing that changed was the database. It works like this: URL has parameter called id in this form: http://example.com/post?id=... Code checks if param is present, otherwise it redirects home. If the param is present, code gets the ID and compares it to the records in the MySQL database hosted by my ISP. Match gets used in an echo statement. A div on the page is activated. Database Layout:

+-------+------------+------------+------------+------------+---------------+
|  id   |    Naam    |  Metgesel  |   Kind1    |   Kind2    |     Email     |
+-------+------------+------------+------------+------------+---------------+
| abc12 |   Bobby    |   Caily    |      *     |     *      | b@example.com |
|  ...  |    ...     |    ...     |     ...    |    ...     |      ...      |
+-------+------------+------------+------------+------------+---------------+

Ok, my subject line may not be exactly what I am looking for and I am not even sure what the subject should be, so let me explain what I am trying to do.

My application is as such that you enter in a zip code and it returns information, however my hard copy has a range of zip codes, in this case, equaling a zone, I.E. 90076-90210 is zone A, now instead of having the following in the database:

Code: [Select]
ID   ZIP        ZONE
1    90076    a
2    90077    a
3    90078    a
...
...
134   90210   a
Could I make it:

Code: [Select]
ID   SZIP        EZIP        ZONE
1    90076      90210     a
and though my PHP/mySQL callout compare the variable to, and find that is ZIP is between SZIP and EZIP to output a?

As there are a couple od thousand zip codes I am trying to minimize my database to be a bit smaller, but am not sure how to code it.  Normally I would make the database have all 99000 entries and pull from the database where ZIP = ZIP, but again I am trying to save my self some time...

Could I make it somehow that if ZIP <= SZIP and >= EZIP output ZONE?

Does this make any sense?  My PHP Coding is unfortunately lacking, I have only been programming it heavily for the last 5 months and it has been basic stuff.  Any help would be appreciated.

How can I insert PHP code inside MySQL DB? I have mixed HTML and PHP code like this:
<div class="rightpanel">
   <div class="hltred">
      <div class="hlthead">
         <p><?php echo $pages->naslov; ?></p>
      </div>
      <div class="hltcontent">
         <p>
            ovde treba da ide loop sa svi podlinkovi za taj glavni koji je aktivan</p>
      </div>
   </div>
</div>,
but when i insert it into DB i get this code (I use htmlspecialchars function to store):
<div class="rightpanel">
   <div class="hltred">
      <div class="hlthead">
         <p>
<!--?php echo $pages--->            naslov; ?&gt;</p>
      </div>
      <div class="hltcontent">
         <p>
            ovde treba da ide loop sa svi podlinkovi za taj glavni koji je aktivan</p>
      </div>
   </div>
</div>

Hey everyone,

im having problems querying the results from the database using this query....

$get_points = mysql_query("SELECT * FROM points WHERE ACOS(
 (SIN(PI() * '41.896301269531' / '180') * SIN(PI() * latitude / '180')) +
 (COS(PI() * '41.896301269531' /'180') * 
  COS(PI() * latitude / '180') * 
  COS(PI() * longitude / '180' - PI() * '-88.744201660156' / '180'))
 )* '180' / PI() * '60' * '1.1515' <= '80'") or die(mysql_error());


Basically what it does it checks the for location with in 80 miles of the lat and long coordinates.

The problem is no result are showing up. I know there are locations because i tested this as an sql code in my database and it ran perfectly, but i can't get it to work using php..

I get no errors, nothing.

can anyone help me out?

the below code as I understand should insert a new record into my database, but it's not.

<?php
$notes = $_POST['notes'];
$cnamedb = $_POST['cname'];
$username = $_SESSION['username'];

mysql_query("INSERT INTO `ccccomma_eve`.`corps` (`id`, `name`, `ticker`, `alliance`, `ceo`, `tax`, `members`, `hq`, `apidate`, `notes`, `notedate`, `updatedby`) VALUES ('', '$cnamedb', '', '', '', '', '', '', '', '$notes', NOW(), '$username'");

echo $cnamedb." Updated";
?>

Any ideas why?

Hey all. I am new to this forum and to PHP as a whole. I though I would try to make a login system using php and mysql. The login and register forms work great but I cannot seem to fully figure out how to let a user change their password. My code partially works. When the user types the correct old password and when the two new password forms confirm, the password changes and the database is updated and the user is taken to a page that tells him that his password was successfully changed. However, the problem is when the old password he types is different than the one in the database, the page that states password successfully changed also appears but the password is not changed in the database. The problem is thus with the SELECT statement. Can anyone please help me find whats wrong. It has been tormenting for a few hours now. Thank you in advance. . I used md5 encryption for the passwords. Here is the section of code that comes after the script makes sure that none of the forms are empty and that the passwords confirm  .

//Create SELECT query to verify that the old password is correct
$qry="SELECT * FROM members WHERE login='" . $_SESSION['SESS_USERNAME'] . "' AND passwd='".md5($_POST['opassword'])."'";
   $result = mysql_query($qry);
   if($result)
   {
   //Create UPDATE query to replace old password with new password
   $updatepasswd="Update members set passwd='".md5($_POST['npassword'])."' where login='" . $_SESSION['SESS_USERNAME'] . "' AND passwd='".md5($_POST['opassword'])."'";
   $update = mysql_query($updatepasswd);
   
   //Check whether the query was successful or not
   if($update) {
   
      header("location: changepasswordsuccess.php");
      exit();
      }
   else {
      die("Query failed");
   }
   }
   else
   {
   header("location: passwordchange-failed.php");
   }
