  1. Hi all ! Is it good practice to a have a separate database for a different group of people, say people in a different country. For e.g. If I run a franchisee business model in different countries, would it be a good thing to have a separate database based on the country? I was thinking of naming the database prepended by country name like USA_mydatabase, Canada_mydatabase and so on. Would that be ok ? What is the best practice in such cases. Thanks all !
  2. Hi, I have been using Hostgator (shared) for years. Recently, last 4 weeks, almost every week for a day when ever I enter my websites, they give me an error like "Error: No Database Connection", then everytime I contact to Hostgator support and they fix it, but they don't tell me what is really going on with my database system. (They just say my websites are not hacked or something they are doing some update, that is the reason.) So my questions are; 1- What can be the problem that I always have an database connection error and my websites are down for some hours everyweek? (I m not a db expert, so can't figure it out) Is it same with other hostings too? (I have not used any others before) 2- Hostgator users: Do you face this kind of problems too? 3- I have seen the "Web Host List" topic, but i don't know if the list was updated, so I would like to know if you have any hosting suggestions that you don't face this kind of problems. Thank you in advance for your replies.
  3. I have been using the below method to access my database for some time now and just wanted to make sure im doing the correct thing. My application runs perfectly but im just trying to improve my programming skills. The classes are all loaded in with an autoloader so in theory using the classes below I could just call: echo User::getUsername(1); Like I say it works fine I would just love some feedback about what other people do and suggestions on something that might run better or looks cleaner. class Db { private static $db_read; private static $db_write; public static method read(){ if( self::$db_read == null ){ //create new database connection is it doesnt exist self::$db_read = new PDO(); } return self::$db_read; } public static method write() { if( self::$db_write == null ){ //create new database connection is it doesnt exist self::$db_write = new PDO(); } return self::$db_write; } class User { public static function getUsername($user_id){ $d = Db::read()->prepare('select * from user where id = ? '); $d->execute( array($user_id) ); $user = $d->fetch(); return $user['username']; } }
  4. I am building an e-commerce site and I am aiming to create a front end displaying my products with an option for customers to buy them, and have a content management system as a back end for an admin to edit product information. Currently I am storing information about my products on a mysql database. I access and display the product info using a while loop. Below is a simplified version of what I am doing without any html to style it. This code will go through the database and each iteration will go the to the next row and display the info about the next product. $query = mysql_query("SELECT * FROM truffleProducts"); while ($row = mysql_fetch_array($query)) { $id = $row['id']; $name = $row{'Name'}; $price = $row{'Price'}; $desc = $row{'Description'}; echo $id; echo $name; echo $price; echo $desc; } I have began to implement a 'buy' button so that customers are able to click on a button next to the product info and purchase it. However I have come across a problem which is where my program won't be able to tell which product you have selected as the number stored in the $id variable will just be the last product it has fetched from the database. I can't differentiate between all the product's buy buttons, so it will impossible to place an order for a customer with the current system I have. Can any one tell me how to get the id number of the specific product that a user has selected? I only started learning PHP a month or two ago so assume I know nothing
  5. Hi, i'm new to php and mysql so any helps will be greatly appreciated. I have the the code below but it looks like it's not working. I need the data id, firstname from table technictians and the total sales(add all sales in the database together) in the everyday_sale table. It's give me the total sale in the second query but not the id and firstname from the first query. If i take out the second query then the first query gave me the id and firstname just fine. It's seem like that two queries dont like each other some how. Thanks in advance and will consider give donation if got the problem solve. <HTML> <HEAD> <TITLE></TITLE> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script> <script src="onpage_submit.js"></script> <META name="description" content=""> <META name="keywords" content=""> <META name="generator" content="CuteHTML"> </HEAD> <BODY BGCOLOR="#FFFFFF" TEXT="#000000" LINK="#0000FF" VLINK="#800080"> <?Php $connection = new mysqli('localhost', 'root', 'Mylovev1@', 'usnailsandspa'); if ($connection->connect_errno > 0) { die ('Unable to connect to database [' . $connection->connect_error .

  7. Hello guys. I got a problem that whenever you register on my page, the registration is successful, no errors, successful redirection to login page, but the registration does not write the information into database and I have no idea why... I'm sure that i'm connecting correctly, to the correct table, with the correct commands, but it kinda does not work... BTW (This registration and login and all worked a few weeks ago, but I got an sudden internal server error, so I had to delete and reupload all files, and I had to change database. I changed the database, created the same table with the same columns, also I overwrote ALL old database information to the new (password, dbname,name) and, so page works fine, but that registration does not...I'm including my code for registration and registration form) Registration process CODE: <?php include_once 'db_connect.php'; include_once 'psl-config.php'; $error_msg = ""; if (isset($_POST['username'], $_POST['email'], $_POST['p'])) { // Sanitize and validate the data passed in $username = filter_input(INPUT_POST, 'username', FILTER_SANITIZE_STRING); $email = filter_input(INPUT_POST, 'email', FILTER_SANITIZE_EMAIL); $email = filter_var($email, FILTER_VALIDATE_EMAIL); if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { // Not a valid email $error_msg .= '<p class="error">The email address you entered is not valid</p>'; } $password = filter_input(INPUT_POST, 'p', FILTER_SANITIZE_STRING); // Username validity and password validity have been checked client side. // This should should be adequate as nobody gains any advantage from // breaking these rules. // $prep_stmt = "SELECT id FROM members WHERE email = ?

  8. Hi I have a question about managing data from forms and database, to be exact for safe input/output data from form input fields. Do i need some filters to remove code from input if user try to insert ? When i making database table i limiting chars and same in form. Here is a piece of code i use just for test and example : // connection to database $dbh = new PDO('mysql:host=localhost;dbname=test123', 'root', ''); $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); // variables to insert into database $username = $_POST['username']; $password = $_POST['password']; $email = $_POST['email']; // query with prepare statements $stmt = $dbh->prepare("INSERT INTO members (username, password, email) VALUES (:username, :password, :email)"); $stmt->bindParam(":username", $username, PDO::PARAM_STR); $stmt->bindParam(":password", $password, PDO::PARAM_STR); $stmt->bindParam(":email", $email, PDO::PARAM_STR); $stmt->execute(); $lastId = $dbh->lastInsertId(); // checking if query is passed and data is inserted into dataabse if($lastId > 0) { echo 'Thank u for register.'; } else { echo 'Something went wrong, please try again.'; }

  14. Hi I’m trying to develop an online application that will allow ‘Candidates’ to book on courses that “Providers” have posted. The application is going to have 4 different types of users, please see attached ‘Figure 1.4 - JobSkilla User Permissions & Roles.jpg’ all of which have different information associated with them. On first signup of a provider they will complete a company profile and a user will be created as the owner associated with that “Provider” that user will then be able to invite their team members (Team associations) to share the same “Provider” data but with restricted access to areas such as billing / invoives. I’m going to be building the application using laravel 5.2, I still want to use laravels Auth but how can I allow multiple auths? I was thinking of having a table called “Auth” that could manage the logins with a forging key to the ‘candidates’, ‘providers’ table. What’s the best way of handling multiple logins that are associated with 1 “Provider”? I’ve attached a EER diagram with the current database design this may be incomplete. I wanted to ask for some guidance with the best way to program/db design the project. I would appreciate if anyone can give me a better solution or point me in the right direction. I don't mind paying for advice. JobSkilla EER Diagram.pdf
  15. Hi there guys, I've a little problem with inserting a file name into a database table. I can't see wich is the problem. The code is bellow and i think the problem is at INSERT INTO part. <?php $path = "./cv/"; $valid_formats = array("doc", "pdf"); if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST") { $name = $_FILES['photoimg']['name']; $size = $_FILES['photoimg']['size']; if(strlen($name)) { list($txt, $ext) = explode(".", $name); if(in_array($ext,$valid_formats)) { if($size<(20480*20480)) // Image size max 20 MB { $actual_image_name = time().$id.".".$ext; $tmp = $_FILES['photoimg']['tmp_name']; if(move_uploaded_file($tmp, $path.$actual_image_name)) { mysqli_query($mysqli,"INSERT INTO formular_client (client_cv = '$actual_image_name')"); } else echo "failed"; } else echo "Image file size max 20 MB"; } else echo "Invalid file format.."; } } ?> <input type="file" name="photoimg" id="photoimg" />
  16. I have a simple user login where it inserts the user session into database like this (id, user_id, hash). It works fine. I can delete the session from the database when the user logs out. Now I realized something. When I close the browser window, it'll destroy the session(log out the user) as intended but it won't delete the session from the database. I was wondering if there is a way to do that?

  18. Hi guys, I have a problem with my code. It connects with the database but it doesn't execute anything. I am trying to update a value in a table but I really don't know what I am doing wrong. I am trying to change the price based on the meta_value GF-1370 Thank you very much. Here is Table (Taken from myphpadmin) meta_id post_id meta_key meta_value 18538 4356 _sku GF-1370 18541 4356 _price 2.343 and here is my code: <?php $link = mysql_connect('server', 'username', 'password'); if (!$link) { die('Could not connect: ' . mysql_error()); } echo 'Connected successfully'; mysql_select_db(wordpress_i12dhflgoa); $sql="update `wp_pzvy_postmeta` set `_price` = 5 WHERE `_sku` = 'GF-1370'"; ?>
  19. Hey guys, I wanted to share something with everyone. I hope this is helpful. This is basically a native solution to easily store PHP session data in a MySQL database. Session variables contain data that is saved for a specific user by associating the user with a unique identity. Typically, PHP would store session variables in a local file system on the server by default. While this may be acceptable to many people who are running small to moderate PHP applications, some larger applications that require load balancing would need to be run on multiple servers with a load balancer. In such cases, each server running PHP would need a way to ensure that sessions continue to work properly. One common way to achieve this is to override where PHP opens, reads, writes, and destroys the session variables so that it can perform these operations on a table inside of a MySQL database. When this is performed, the web application can gain advantages such as session management, session logging, and session interactions. I have provided my source code for your reference here: https://github.com/dominicklee/PHP-MySQL-Sessions Hope this helps someone out!
  20. Hello everyone, I'm going to create my school project and I really need your advice. My Project Summary I need to create a new website where the user can add new schools in my site. After creating, they can add students, add teachers, add principal and hell lot of things from their admin panel. And in the frontend they will get their own urls and can display their schools. Ex1: example.com/st_sebastians/ <------- School name. Ex2: example.com/st_augustin/ <------- School name. When the user will visit those url they will see all the contents of their respective schools. My Questions How can I create those database. For that I've thought of two methods. 1) I will create multiple database for every user/school dynamically using php and saves the record in it. (I searched on google that it is very prone to mysql injection.) 2) I will create a single database with everything related to their (school id) and stores in the single database. Example Student table id | school_id | name | roll | ---------------------------------------------- 1 | 1 | Subho | 123456 ---------------------------------------------- 2 | 5 | xyz | 236566 ---------------------------------------------- 3 | 45 | asfgf | 778219 . . . . . . . . Please note that the database are going to store whole lot of records and I don't want to it slow down. Any Help will be highly appreciated. Thank You In advance...
  21. I am trying to connect to my database on xammp, Im trying to find info how to connect and set up for people that sign in to my website they can regsiter for it.
  22. Here's what I am trying to do. Users Table user_id, sponsor_id, username, filled_positions, position_1, position_2, position_3, position_4, position_5 1 0 user 1 4 user 2 user 3 user 4 user 5 2 1 user 2 2 user 4 user 5 3 1 user 3 4 2 user 4 5 2 user 5 Above is a "Users" table. Here's what I am trying to do. Insert new users into the table. Say I already have the users table set up with 5 users. I want to add User 6. I want to loop through the users in the table and find the next empty position and update it with the new user id. In this scenario diagram above, the next empty position is Row 1 - position_5. The one after that is Row 2 - position_3 and then Row 2 - position_4...etc. It basically loops through rows and checks each position. So User 6 will be placed under Row 1 - position_5 and User 7 will be placed under Row 2 - position_3. How can one go on about doing that?
  23. Hello users: I am exploring the delightful world of PHP for web applications. I am in the stage where I need to use SESSIONS and COOKIES and MYSQL for a user/membership/profile structure. I understand most of the grammar behind PHP and am excited to apply this in application. I am searching for recommendations and comments about using: 1. COOKIES 2. SESSIONS 3. MYSQL/SQL Almost every website has an authentication mechanism, profile, and use information. My website required this similar structure, but I have been having some problems completing all of the technical steps for production. If anyone has code samples or places where I can review code on this topic, that would be wonderful. I am specifically searching for more advanced topics in these area for general robustness. Please kindly send me a message or respond to this post. Regards, Diamond
