PHP - Why Db Connection Fails With Config.php But Not With Direct Db Call ?
I have no clue why my DB connection does not work when I try to use constants but does work with I use direct values, ie If I do a mysql_connect=(localhost, vincej, secretpwd); is works.
If I do a connection with a config.php where I define the constants it fails with the error message Unknown MySQL server host 'DB_SERVER' (11001) Config.php : Code: [Select] <?php // Database Constants defined('DB_SERVER') ? null : define("DB_SERVER", "localhost"); defined('DB_USER') ? null : define("DB_USER", "vincej"); defined('DB_PASS') ? null : define("DB_PASS", "secretpwd"); defined('DB_NAME') ? null : define("DB_NAME", "sales"); ?> Then my DB class is: Code: [Select] require_once("config.php"); <?php class MySQLDatabase{ private $connection; // Runs function open_connection upon creation of class. function __construct() { $this->open_connection(); } // Opens connection nad selects DB public function open_connection() { $this->connection = mysql_connect(DB_SERVER, DB_USER, DB_PASS); if (!$this->connection) { die("Database connection failed: " . mysql_error()); } else { $db_select = mysql_select_db(DB_NAME, $this->connection); if (!$db_select) {die("Database selection failed: " . mysql_error()); } } } } ?> I'm new to OOP and all help is VERY gratefully received ! thansk VJ Similar TutorialsI have the following code for a very simple registration form handler -
//require('../../config/config.php');
require('reg_functions.php');
//assign clean form variables
$firstname = clean_names($_POST['firstname']);
$lastname = clean_names($_POST['lastname']);
$username = clean_names($_POST['username']);
$email = clean_email($_POST['email']);
$email2 = clean_email($_POST['email2']);
$password = clean_password($_POST['password']);
$password2 = clean_password($_POST['password2']);
$date = date("Y-m-d");
if(isset($_POST['register_button'])) {
//validate & confirm emails match
if($email == $email2) {
if(filter_var($email, FILTER_VALIDATE_EMAIL)) {
$email = filter_var($email, FILTER_VALIDATE_EMAIL);
// I THINK I COULD DEF MAKE THIS EMAIL CHECK CLEANER - WORK ON THAT LATER
//check if email exists in system already
$email_check = mysqli_query($conn, "SELECT email FROM users WHERE email='$email'");
//number of rows returned with the email (this should be 0 to proceed)
$number_rows = mysqli_num_rows($email_check);
if($number_rows > 0) {
echo "Email already in use <br>";
} else {
echo "email is correct <br>";
}
} else {
echo "Invalid email format <br>";
}
} else {
echo "Emails don't match <br>";
}
echo "First Name: " . $firstname . "<br>";
echo "Last Name: " . $lastname . "<br>";
echo "Username: " . $username . "<br>";
echo "Number of Rows: " . $number_rows . "<br>";
}
the code that starts with the mysqli_query() function to check for matching emails is where it fails (white screen). I figured it may be because the $conn variable wasn't being associated with the $conn variable in the config.php file. So I added the require config.php at the top. Now it only works if both are commented out. So in reality this could be 2 issues and I struggled with how not to ask too many questions in one post though they may be the same issue. I'm really new to php. Can someone explain the mechanics of whats going on (or not going on). to recap, this is the code that caused the white screen initially -
// I THINK I COULD DEF MAKE THIS EMAIL CHECK CLEANER - WORK ON THAT LATER
//check if email exists in system already
$email_check = mysqli_query($conn, "SELECT email FROM users WHERE email='$email'");
//number of rows returned with the email (this should be 0 to proceed)
$number_rows = mysqli_num_rows($email_check);
if($number_rows > 0) {
echo "Email already in use <br>";
} else {
echo "email is correct <br>";
}
and I realized it had no association to the $conn variable in the config.php file so I added the require config.php line at the top. This above code is obviously still not working and if I comment it out, the require config.php line still causes a white screen. This is my config file -
ob_start();
session_start();
$timezone = date_default_timezone_set("America/xxxxxxxx");
$db_host = "localhost";
$db_user = "root";
$db_pass = "";
$db_name = "qcic";
$conn = mysqli_connect( $db_host, $db_user, $db_pass, $db_name );
if( $conn->connect_errno) {
printf( "Connect Failed: %s\n", $conn->connect_error);
exit();
} else {
echo "Connected to database";
}
ob_end_flush();
and I get the "Connected to database" echo so I have no idea what the problem is. Anyone with some time and more experience that can explain some of these things? thanks Where do PHP configuration settings (e.g. Error-Handling Levels) exist? I believe they are in a file somewhere?! Thanks, Debbie where does the connection details go and in what manner order etc, server url, username, password <?php define( "DB_DSN", "); define( "DB_USERNAME", " ); define( "DB_PASSWORD", " ); define( "PAGE_SIZE", 5 ); define( "TBL_", " ); define( "TBL_", "" ); ?> This topic has been moved to Other Libraries and Frameworks. http://www.phpfreaks.com/forums/index.php?topic=319682.0 OVERVIEW: The code is about making call to the escreen web service using SOAP and Curl with client authentication required.

I don't know how to do it here(pass the method name to call). 2. For client authentication they gave us three certs, one root cert, one intermediate cert and a client authentication cert PROTPLUSSOL_SSOpem(it was a .pfx file). Since we are on linux we converted them to pem . In curl calls I could not find way to how to include both the root cert and the intermediate cert ,so I combined them by making a new pem file and copying the intermediate cert and them the root cert and naming it authority.pem . I am not sure whether it works or not and would like your opinion. 3. For the current code Iam getting the error Error no : 77 Curl error: error setting certificate verify locations: CAfile: /home/pps/authority.pem CApath: /home/pps/ If I disable the curl error message,I am getting blank page with page title 403 - Forbidden. Access is denied. If I comment out the CURLOPT_CAPATH and CURLOPT_CAINFO lines it gives http 500 error page with the message as content and the following at the top. > HTTP/1.1 500 Internal Server Error.

So I would request you to help me out by pointing out whats wrong with the current code. Thank you. Hi, I recently updraded PHP to 5.3.3 and Apache to 2.2.17 on a Linux Centos 5.4 Box using yum. Since then the Web pages running under Apache cannot connect to the database using mysql. If I run a manual PHP script, I am able to.

Do I need to rebuild / reintall Apache manually? Thanks very much! Frank Hi guys, I want to set up a php script to connect to php sources on another site, something is like this: <?php $mysql = array ( 'host' => 'http://www.mysite.com/myscript.php', } <?php try { include_once('mysql_connect.php'); } Is the source is correct to use that I want to read the script while hide the actual url in the config php script?? Thanks, Mark I have a PHP script that is encrypted with Ion Cube. Since I don't want to violate the license, I can't modify anything in the script. The script makes calls to an XML based config file. I want to create a database to store the config data and then feed it to the encrypted script based on the referer URL that made the request. Basically, I want to "virtualize" the config XML file so I can feed the encrypted script the data I want based on the referer URL. Any ideas? I'm really embarrassed asking this.. I have two files. config.php & program.php config.php<php $max_columns = 3; ?> program.php<?php include ('config.php'); echo $max_columns; ?> I can't get the script to echo anything. I have tried... $max_columns = '3'; $max_columns = "3"; include_once include ("config.php"); include ('/path/to/file/config.php'); require .....etc. etc. Any thoughts? PLEASE, I'm going nuts here. Thanks for you patience with what must be a very trivial question for you guys I have a very simple password protection set-up on a page as a temporary measure until I can set something better up. The person I set it up for wants to be able change the Username and Password occasionally but wants me to set up a simple form which will overwrite the data in the config file (connection.php) instead of having to open the file himself (don't ask!). I have has a read round to see if there is any obvious and simple solutions but none seem as simple as I had hoped. I intend to work on a system via MySQL where there can be multiple users and passwords but as time is tight at the moment I just want to get something basic and working. The nature of the 'hidden' content is not sensitive (it is just a football clubs live commentary stream that they are hoping to get people to subscribe to) so there are no issues at this moment with security. All he needs to do is choose a new Username and Password every game and email it to the subscribers. The data that he wants to update in connection.php, via a form, is Code: [Select] $username = "user"; $password = "pass"; The code in the actual page with the log-in is Code: [Select] <?php require_once('connection.php'); if ($_POST['txtUsername'] != $username || $_POST['txtPassword'] != $password) { ?> <h1 style="color: #FFF">Login</h1> <form name="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> <p class="white_text"><label for="txtUsername">Username:</span></label> <br /> <input type="text" title="Enter your Username" name="txtUsername" /></p> <p class="white_text"><label for="txtpassword">Password:</label> <br /> <input type="password" title="Enter your password" name="txtPassword" /></p> <p><input type="submit" name="Submit" value="Login" /></p> </form> <?php } else { ?> CONTENT TO BE SHOWN................Is there a simple way of creating a form just to update those two bits in the connection.php or will I have to bite the bullet and set it up via MySQL from the off? Thanks in advance Steve Hi! I am new to PHP and I googled a lot before coming here. I have trouble accessing localhost/community/admin/board_functions.php from a folder which path is localhost/community/boards/test/index.php, which script is the one below. What path should I put on require_once to access the script? Thanks in advance Code: [Select] <?php require_once "..admin/board_functions.php"; $board_location = explode("\\", __DIR__); $board_name = $board_location[5]; $board_title = board_title($board_name); echo $board_title; ?> I work for a small web design company who use their own servers. When I write PHP scripts on their server i can pass variables over pages and then grab them on the other side by just using that variable again. Like if I had a form input like: <input type="text" name="bob"> Then when the form is submitted I can use $bob on the next page without having to do somthing like: $bob = $_POST['bob']; But when using xampp or some other hosting that I have used I HAVE to use the $_POST['bob'] or $_GET['bob'] to grab the variable. What setting is it that makes this possible, is it in the PHP ini? Thanks for any answers I can call the following function successfully as a single php program // Acknowledge and clear the orders function ack($client, $merchant, $id) { $docs = array('string' => $id); $params = array('merchant' => $merchant, 'documentIdentifierArray' => $docs); $result = $client->call('postDocumentDownloadAck', $params); return $result; } with $result = ack($t, $merchant,'2779540483'); successful output [documentDownloadAckProcessingStatus] => _SUCCESSFUL_ [documentID] => 2779540483 I'm trying to figure out how to call this function as an object from another program.

Something like this (modified data, of course): <?php // database information $dbhost = 'localhost'; $dbuser = 'root'; $dbpass = '******'; $dbname = 'databasename'; ?> Can a hacker access those variables? How can I protect this? Ideas, suggestions? Thanks in advance! Hi there, I am trying to create a custom registration form and connect the file to mysql using a config.php file. I created the file with a tutorial. I placed both the config.php and the registration.php in a "page-templates folder" inside the "theme folder". Using wordpress "add new page" I am able to select the registration.php file as a template. I am able to open the newly created page and type in information like username and password. I am able to press submit and I get redirected to a new page.
Problem: I would really appreciate your help. Siegfried Hey all. I've created a script that updates a website's config in a database. The script itself works fine but I feel it is rather uncanny. Where can I look to find better methods of achieving what I'm trying to accomplish? Here's my script that updates my table with columns id, showlogin, colorscheme, blogmenu, aboutus. I explain the script below it. if (isset($_POST['submit'])) { // id will always be 1 and only query if only submit was pressed $sql = "UPDATE config SET id=1"; // showlogin values are 1 for show login form and 2 for don't if(!empty($_POST['showlogin'])) { $showlogin = $_POST['showlogin']; $sql .= ", showlogin='$showlogin'"; } if(!empty($_POST['colorscheme'])) { $colorscheme = $_POST['colorscheme']; $sql .= ", colorscheme='$colorscheme'"; } if(!empty($_POST['blogmenu'])) { $blogmenu = $_POST['blogmenu']; $sql .= ", blogmenu='$blogmenu'"; } else { $sql .= ", blogmenu=2"; } if(!empty($_POST['aboutus'])) { $aboutus = $_POST['aboutus']; $sql .= ", aboutus='$aboutus'"; } else { $sql .= ", aboutus=2"; } mysql_query($sql, $connect) or die (mysql_error()); } It works like this. I have a form with a few selects and checkboxes. The selects are the colorscheme and showlogin. The checkboxes are blogmenu and about us, both defaulting to the number 2 if they are not checked. 1 means show this item on the live site and 2 means do not show. This is pulled out of the database on page loads. So, I hope I was clear as my mind is spaghetti right now. Cheers! To me it is logical to store config data such as site name, meta, etc in a php file rather than storing ina table in mysql database. This will reduce the number of calls to the mysql database, as these are key parameters and needed in every page. But, a well-developed CMS like Wordpress uses a mysql table to store such basic data. What is your idea? Ain't it better to reduce mysql loads? This is my first post on your forums. I've some problems with a registration form that I've been trying to work out for 2+ days now, asking about it here is a last resort - I have a config.php file located at config/config.php there's a register.php file in the sites root directory and a includes/form_handlers/register.php

$database = "social";
$conn = mysqli_connect($servername, $username, $password, $database);
if (mysqli_connect_error()) {

I can't get the reg. form handler to recognize the $conn variable from the config.php file. if I add require '../../config/config.php'; to it I get this error:
Warning: require(../../config/config.php): failed to open stream: No such file or directory in /opt/lampp/htdocs/qcicnews/includes/form_handlers/register.php on line 3 I don't know why it can't find that file, but the way I understand PHP is that I don't need that line because it's in the register.php. When I don't use it I get a party of errors all connected to it not recognizing the $conn variable:
Notice: Undefined variable: conn in /opt/lampp/htdocs/qcicnews/includes/form_handlers/register.php on line 43
There's about 6 more that look like the ones above but from different lines where $conn is referenced, I just deleted them for brevity sake. I'm pretty new to PHP and this is the most difficult situation I've encountered so far, can someone help me find the way here?
I'm very fresh to php coding, and embedding it in html, so I'm a bit lost here. I have made a script for doing backups of mysql on the QNAP box, I want to make a page to set the variables in it, so the users don't have to change directly in the script like they do now. First the page should read in the current config, and display that in the form, and then users can change the values, and press save, quite simple I'm sure for the experienced php coder :-) I'm not sure if it's a HTML or PHP question, so here goes, if it's in the wrong forum, maybe the moderator will forgive me, and move the topic to the right one. THe page I've currently created looks like this: Code: [Select] <html><body> <h1>Mysql Backup Script</h1> <?php $config=parse_ini_file("config.txt"); ?> <form action="writeconfig.php" method="post"> <p>Days to save config: <input type="text" name="configdays" value="<?php echo $config('configdays'); ?>"/> <br> <p>Name of Backup location (share): <input type="text" name="share" value="<?php echo $config('share'); ?>"/> <br> <p>MySQL Backup User: <input type="text" name="user" value=<?php echo $config('user'); ?>"/> <p>Errorlevel (0=off, 1=error, 2=error+warn, 3=error+warn+info: <select name="error"> <option>0</option> <option>1</option> <option>2</option> <option>3</option> </select> <br> <p><input type="submit" value="Save" /> </form> </body></html> The problem is that it doesn't show the variables in the value fields, but rather the php code And the writeconfig.php looks like this: Code: [Select] <?php $configdays = $_POST['configdays']; $share = $_POST['share']; $user = $_POST['user']; $error = $_POST['error']; $int_options = array("options"=>array("min_range"=>1, "max_range"=>100)); if (!filter_var($configdays, FILTER_VALIDATE_INT, $int_options)) die("Value for number of config days is incorrect allowed value is 1-100"); $fp = fopen("config.txt", "w"); fwrite($fp, "configdays=" . $configdays . "\r\n" . "share=". $share . "\r\n" . "user=". $user . "\r\n" . "error=". $error . "\r\n"); fclose($fp); echo "Config file successfully written" ?> It's all still very raw, but the write part works ok, still needs a lot of input validation of course. As you can see, I'm still in the beginning part of this, so if I'm doing something wrong, or there's another way to do it properly, let me know! |
