PHP - Mysqli Not Working After Converting From Mysql
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.

I'm pretty new at building websites using php (and mysql) and was most recently given the task to create a database image gallery, which was to be accessed through a php website.
I made a full site which allowed me to upload said images & it worked perfectly. However after doing my last checks I have been told that mysql is deprecated and that I need to use mysqli.
I've had a look at some tutorials on websites to help direct me but it's simply confusing me more and more each time I look at it.
Is it possible I am over thinking this and there is an easier way to approach it?
Thank you kindly.
This is my php code:

Hey. I was writing my class object for a database connection and while I was writing the query part, I came to wonder whether I should use mysql_real_escape_string or mysqli_real_escape_string to make the query mysql friendly, what's the difference? I am new to MySQLI and tried to test the rollback functionality. I created a simple database called mysqli and one table called test with and id and name field. my PHP is as follows: Code: [Select] $mysqli = new mysqli('localhost',name,password,'mysqli'); $mysqli->autocommit(FALSE); $result = $mysqli->query("INSERT INTO test (name) VALUES('bla')"); $mysqli->commit(); $mysqli->rollback(); After hitting the page, it does the insert, but does not roll back the transaction. So it ends up being inserted into the DB. Why is the rollback not working? Hello guys,
I have been away for a couple of days. Its nice to be back
Yesterday night I was practicing an AJAX/PHP delete tutorial and file "delete.php" was wrtiten in mysql* which I converted to PDO but it didnt seem to work after conversion. The three bits of code are as follows
//I got the results using PDO::FETCH_ASSOC in following div getting ID of row in link while ($r = $getData->fetch(PDO::FETCH_ASSOC)){ echo (" <div class='record' id='record-".$r['id']."'> <a href='?delete=".$r['id']."' class='delete'>[x]</a> </div> "); } $(document).ready(function() { $('a.delete').click(function(e) { e.preventDefault(); var parent = $(this).parent(); $.ajax({ type: 'get', url: 'delete.php', data: 'ajax=1&delete=' + parent.attr('id').replace('record-',''), beforeSend: function() { parent.animate({'backgroundColor':'#fb6c6c'},300); }, success: function() { parent.slideUp(300,function() { parent.remove(); }); } }); }); });and delete.php contains include "inc.connect.php"; if(isset($_GET['delete'])){ $id = $_GET['delete']; $query = "DELETE FROM tempdata WHERE id=?"; $runThis = $db->prepare($query); $runThis->bindValue(1,$id); $runThis->execute(); } /*The problem I am facing is in delete.php. because If i run the same script in mysql_*, it works, which is as follows first (I had to write connect in mysql as original connection is written in PDO) ------------------------------------------------------ $con = mysql_connect('localhost','munni****','*******'); mysql_select_db('stockcontrol',$con); if(isset($_GET['delete'])) { $result = mysql_query('DELETE FROM tempdata WHERE id = '.(int)$_GET['delete'],$con); } mysql_close($con); */ Edited by Digitizer, 11 September 2014 - 07:08 AM. Hi, I only just worked out (a little slow) that mysql is not redundant and crap =\ Apparently I should be using mysqli.
However I need help I tried following a tutorial online but it failed. This is my login script and it doesn't work
<?php require_once '../inc/conn.php'; session_start(); if ($_POST['username']) { $username = $_POST['username']; $password = $_POST['password']; $requestLogin = mysqli_query( $retreat, "SELECT * FROM login WHERE username='$username' AND password='$password'"); while($row = mysqli_fetch_array($requestLogin)){ $userID = $row['userID']; $_SESSION['userID'] = $userID; $username = $row['username']; $_SESSION['username'] = $username; header('location: /administrator/'); } } ?>And this is the conn.php ( something hidden for safety, however it does connect correctly. <?php $hostname = 'localhost'; $username = ''; $password = ''; $database = ''; $retreat = mysqli_connect($hostname, $username, $password, $database) or die('Connecting to MySQL failed'); ?>The actual <form> is also correct as it's just normal html and worked before I tried converting to mysqli. After this login I have a script which is this that goes in the header of all admin pages. <?php require_once '../inc/conn.php'; session_start(); if (isset($_SESSION['userID'])) { $username = $_SESSION['username']; $getUser = mysqli_query( $retreat, "SELECT user_rights FROM login WHERE username='$username'"); while($row = mysqli_fetch_array($getUser)){ $user_rights = $row['user_rights']; } } else { include_once 'login.php'; exit(); } ?>I am no coding professional by any means but I get the job done. However this mysqli is sort of new ground. On the mainpage I am getting this error:
Fatal error: Call to a member function query() on a non-object in C:\xampp\htdocs\page\controller\function.php on line 393
$result = $db->query($query);And on the admin section: Notice: Undefined index: role in C:\xampp\htdocs\page\admin\header.php on line 7 Notice: Undefined index: role in C:\xampp\htdocs\page\admin\header.php on line 7 Fatal error: Undefined class constant 'site_url' in C:\xampp\htdocs\page\admin\header.php on line 8 if ($_SESSION['role'] !== 'admin' and $_SESSION['role'] !== 'moderator'){header( 'Location:'.config::site_url.'index.php' ); Alright guys, I see people recommending prepared statements (PDO/MySQLi) and saying that they are way to go these days. However upon doing a bit more research, I've found that prepared statements, PDO in particular, is lacking in terms of performance, especially using SELECT statements. Now I'm starting a new project, which is basically a text based game with lots of queries and DB interaction, so I'm really interested in knowing what's the best approach for me. I was leaning towards PDO but I don't want it crawling my server under heavy load. I appreciate any advices or first hand experiences on this. Hello, I've been tasked with updating our code base from mysql to something that will work with php 7. It's older code that was written by 2 or 3 individuals before me and it's not at all object oriented. There are about 540 different files that I will end up having to edit to make it all up to date. I'm not a very experienced programmer myself, and I'm in need of some guidance. There are some files that have functions that call and use mysql queries three or four files deep and going through and editing one function leads me to having to update 4 or 5 other files which breaks stuff somewhere else down the road. I was wondering if anyone has some suggestions on ways to make this process less painful. The other thing is that by using PDO in a not OO style, it seems like I'm losing a lot of its benefits. Should I consider using MYSQLi instead of PDO considering the circumstances? Are there any resources that you could point me to in order to help me learn the skills I need to make it through this upgrade? Thanks for the help! Hi, i have a user update function in my code so I can easily change user fields int he database public function updateUser ($username, $value, $what) { $q = "UPDATE `users` SET ? = ? WHERE username = ?"; if ($stmt = $this->db_connection->prepare($q)) { $stmt->bind_param("sis", $what, $value, $username); $stmt->execute(); } } The database is connected successfully, but say i run a updateUser('blaine0002', 'blah', 'password'); nothing would get updated and no errors are thrown. Am i doing something wrong? Thank you! Hi, I am trying to convert the register & login script from mysql to mysqli. I have converted the easy parts and have the connection to the database, but the following functions all need changing and I can't work out the correct solution mainly due to the deprecation of mysql_result() The code that needs updating is <?php function user_count() { return mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `active` = 1"), 0); } function users_online() { return mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `logged_in` = 1"), 0); } function change_profile_image($user_id, $file_temp, $file_extn) { $file_path = 'images/profile/' . substr(md5(time()), 0, 10) .

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 Hello , this is my first post in this forum , i would like to see the following code and tell me your opinion , not about the security issues not about how good or bad it is. Its just a simple demonstration in order to show you the problem.
<?php include('config/functions.php'); $mysqli = connectionToDb(); $mysqli->autocommit(FALSE); $stmt = $mysqli->prepare("INSERT INTO users (first_name,last_name) VALUES ('stelios','stelios2')"); $stmt->execute(); $stmt->close(); $stmt = $mysqli->prepare("INSERT INTO users (first_name,last_name) VALUES ('stelios3','stelios4')"); $stmt->execute(); $stmt->close(); var_dump($mysqli->commit()); $mysqli->close();This is the code and the var_dump($mysqli->commit()); line prints false ! BUT , the inserts are in the database. If i comment out the commit line , then nothing is in the database. Can you advise ? Thanks !

Any help will be much appreciated. Paulo Borges 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 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.

I need it to get the data from a mysql database and then export it as a json array in the format of id , title, author, date, imageUrl, text. (Please not that these are all variables ) PHP CODE: Code: [Select] <?php $link = mysql_connect('localhost', 'root', ''); if (!$link) { die('Could not connect: ' . mysql_error()); } echo 'Connected successfully'; $arr = array(); $rs = ("SELECT `id`, `title`, `author`, `date`, `imageUrl`, `text` FROM `items`"); while($obj = mysql_query($rs)) { $arr[0] = $obj->id; $arr[1] = $obj->title; $arr[2] = $obj->author; $arr[3] = $obj->date; $arr[4] = $obj->imageUrl; $arr[5] = $obj->text; } echo '{"items":'.json_encode($arr).'}'; ?> Thanks For Your Help borden0108 When I echo the POST, it echoes the correct value. The MySQL portion seems to just ignore it all together. I've tried changing the dropdown option to just a text field, same thing occurred. I have text fields right above this particular one that update just fine with the SAME exactly scripting. if POST, update query, done. Works. This one for some reason will not. MySQL portion: if ($_POST['bUpdate']){ mysql_query("UPDATE `Patients` SET `b` = '$_POST[bUpdate]' WHERE `id` = '".$_GET['id']."'"); } echo $_POST['bUpdate']; Form Portion: Code: [Select] <tr onmouseover="color(this, '#baecff');" onmouseout="uncolor(this);"> <td width="310" colspan="2" align="center"><span class="fontoptions">Postcard Status </span><br /> <? if ($data['b'] == 1){ echo '<select name="bUpdate"><option value="1" selected>Yes</option><option value="0">No</option></select>'; } else { echo '<select name="bUpdate"><option value="1">Yes</option><option value="0" selected>No</option></select>'; } ?> </td> </tr> guys, im having a problem here... i tried too many ways to convert dates in american format, to brazilian format, but no one is working... how can i do that, to convert it to dd/mm/yyyy (it comes from my db in mysql)... I know this is probably something very dumb but I am having trouble with my if else. I have a sql query that looks for a record and if nothing is found it echos a warning. Code: [Select] <?php $sql7="SELECT * FROM `$tbl_name2` WHERE Mac = '$Mac' AND Type = '$Type'"; $result7=mysql_query($sql7); if($result7) { while($row=mysql_fetch_array($result7)) echo "The phone you are using with mac $row[0] $row[1] is a Cisco IP Phone! <br>" ; } else { echo "<img src=\"stop.png\"/> The phone you are trying to use with mac $row[0] $row[1] is not a correct Mac\Type. <br> Please confirm the mac and type again."; } ?> I believe my syntax is correct as my if echo works fine. However, when no records are found I do not see my last else echo. Any input? |
