  1. In my database table, i have a field for price and quantity. Is there a way I could use a select to get 2 values from the database? What I mean is I will create a select field where when I select wholesale it will bring out the price and quantity and if I select retail, it will bring the price and the quantity.
  2. Hello everyone, I am a total newbie in PHP and so do here. I am trying to build a table consisting foreign key and primary key and it is showing error like "Parse error: syntax error, unexpected 'cities' (T_STRING) in line number 29". I have marked up my lines according to sublime text 3 editor. I am trying to create a database. 1 <?php 2 $servername = "localhost"; 3 $username = "username"; 4 $password = "password"; 5 $dbname = "newDB"; 7 // Create connection 8 $conn = new mysqli($servername, $username, $password, $dbname); 10 // Check connection 11 if ($conn->connect_error) { 12 die("Connection failed: " . $conn->connect_error);} 14 $firstname = $conn->real_escape_string($_REQUEST['firstname']); 15 $lastname = $conn->real_escape_string($_REQUEST['lastname']); 16 $address = $conn->real_escape_string($_REQUEST['address']); 17 $city = $conn->real_escape_string($_REQUEST['city']); 18 $country = $conn->real_escape_string($_REQUEST['country']); 19 $phone_number = $conn->real_escape_string($_REQUEST['phone_number']); 20 $email = $conn->real_escape_string($_REQUEST['email']); 22 // Attempt insert query execution 23 $sql1 = "INSERT INTO cities VALUES ('$city')"; 25 $sql2 = "INSERT INTO countries VALUES ('$country')"; 27 $sql3 = "INSERT INTO Contacts (firstname, lastname, address, city, country, phone, email) VALUES ('$firstname', '$lastname', '$address', $city, $country, '$phone_number','$email')"; 29 SELECT * FROM cities; SELECT * FROM countries; SELECT * FROM Contacts; if($conn->query($sql1) === true){ echo "City added successfully."; } else{ echo "ERROR: Could not able to execute " . $conn->error; } if($conn->query($sql2) === true){ echo "Çountry added successfully."; } else{ echo "ERROR: Could not able to execute " . $conn->error; } if($conn->query($sql3) === true){ echo "Çontact added successfully."; } else{ echo "ERROR: Could not able to execute " . $conn->error; } // Close connection $conn->close(); ?>
  3. Could someone explain to me why this connection/query succeeds <?php DB::getInstance()->query("SELECT username FROM users WHERE username=?", array("TechnoDiver")); But when I do this it comes back as failed <?php $user = DB::getInstance()->query("SELECT username FROM users WHERE username=?", array("TechnoDiver")); if($user) { echo "success -> "; } else { echo "fail -> "; } like I said I ran tests for the DB->query in the query method and it comes back successfully. It's only when I try to assign it that it comes back failed. Why??
  4. Hello. I am using a form to send data to my database but when I submit the form, the data is not shown on the database. I am connected to the database so I don't think the problem lies there. Also, I have a redirect option via 'Location:' which also works. I am following online examples for the php. This is the PHP I am using: <?php include("dbcon/database-conn.php"); if (!empty($_POST)) #($_SERVER["REQUEST_METHOD"] == "POST") { $pagelinks = $_POST['pagelinks']; $title = $_POST['title']; $asideleft = $_POST['asideleft']; $body = $_POST['body']; $asideright = $_POST['asideright']; $sourceref = $_POST['sourceref']; $sourceimg = $_POST['sourceimg']; $q = "INSERT INTO pages (pagelinks) VALUES ('$_POST[pagelinks]')"; if ($_POST["add_record"]){ header('location:index.php'); exit(); } } ?> The form 'name' values match. As you can see I have tried two methods of 'Post' but neither seem to work. I would like to point out that this is an offline, local test and that I am aware that I am not using real_escape_strings, but I will, once I get the code to work. Also, I am aware of PDO, which I have tried but it is too complex, for me to solve right now. I am familiar with mysqli (including OOP), but am still learning.. I would be grateful if you can help solve my current issue. Thanks in advance for any help.
  5. 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.
  6. 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. 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 !
  8. I currently have a php code at the top of the page that would automatically delete a user from the database if a certain condition isn't met before 24 hours. This code is processed no matter where you are on the site. I have two questions. 1. Will this be an issue if the database has thousands of users? 2. Is there a better way to do this?
  9. I've been asked to create an online inventory system for multiple vendors. The data should be stored in a way that allows searching on product parameters; the simple ones like color, size and other parameters like schedule times, expiration and must be of age. The vendor list is varied, including food, clothing, automotive parts, services and ... you name it. The parameters are so varied and rich that I can't come up with a simple scheme of how to record the information. I thought of a table with 'meta' columns that rely on a product characteristics to define them, or just a huge text field with a delimited list of paramters; like size:14, color:red, or product type tables; table_clothing, table_coatings, table_travel... My class analogy would be automotive_services extends product many times over. What ever I decide to do, I'll wind up chucking it as I've never thought about this kind of an inventory database. I'd like to hear from a e-commerce guy on how they did it. Thanks for any suggestions.
