Thank you so much for the reply. Yeah I know copying from a book is risky but how do I learn? And if you say outdated in what sense please? The book is not that old I did what you said and now I get the following error which does not make sense: Notice: Undefined index: password in /var/www/html/kvcms/ww.incs/basics.php on line 9 Is this index not defined in the file config.php? which looks like this: <?php $DBVARS = array( 'username' => 'cmsuser', 'password ' => 'cmspass', 'hostname' => 'localhost', 'db_name' => 'cmsdb' ); Your help is really appreciated. I want to learn this

I am a newbie I am trying to build a CMS as described in a book. There are 5 files so far and I am sure I copied the code exactly from the book as is but I get the following error when I ru the script: Fatal error: Class 'Page' not found in /var/www/html/kvcms/index.php on line 11 So there are the handler index.php <?php // { common variables and functions include_once('vv.inc/common.inc'); $page = isset($_REQUEST['page']) ? $_REQUEST['page'] : ''; $id = isset($_REQUEST['id']) ? (int) $_REQUEST['id'] : 0; // } // { get current page id if (!$id) { if ($page) { // load by name $r = Page::getInstanceByName($page); if ($r && isset($r->id)) $id = $r->id; unset($r); } if (!$id) { // else load by special $special = 1; if (!$page) { $r = Page::getInstanceBySpecial($special); if ($r && isset($r->id)) $id = $r->id; unset($r); } } } // } // { load page data if ($id) { $PAGEDATA = (isset($r) && $r) ? $r : Page::getInstance($id); } else { echo '404 thing goes here'; exit; } // } echo $PAGEDATA->body; then you have the common include file that just calls the basics.php file and that is supposed to load the page.php file and reference the Page object. Which is clearly not happening. The book tells me that you can call and object (or load it) without including the file if you use an autoload function which is included here. Where is the mistake please? The basics.php file <?php session_start(); function _autoload($name) { require $name . '.php'; } function dbInit() { if(isset($GLOBALS['db'])) return $GLOBALS['db']; global $DBVARS; $db = new PDO('mysql:host='. $DBVARS['hostname'] . '; dbname='. $DBVARS['db_name']. $DBVARS['username'], $DBVARS['password']); $db->query('set name utf8'); $db->num_queries = 0; $GLOBALS['db'] = $db; return $db; } function dbQuery($query) { $db=dbinit(); $q=$db->query($query); $db->num_queries++; return $q; } function dbRow($query) { $q = dbQuery($query); return $q->fetch(PDO::FETCH_ASSOC); } define('SCRIPTBASE', $_SERVER['DOCUMENT_ROOT'] . '/'); require SCRIPTBASE . '.private/config.php'; if(!defined('CONFIG_FILE')) define('CONFIG_FILE', SCRIPTBASE. '.private/config.php'); set_include_path(SCRIPTBASE. 'vv.php_classes' . PATH_SEPARATOR.get_include_path()); ?> the page.php file <?php class Page { static $instances = array(); static $instancesByName = array(); static $instancesBySpecial = array(); function __construct($v, $byField = 0, $fromRow = 0, $pvq = 0) { # byField: 0=ID; 1=Name; 3=special if (!$byField && is_numeric($v)) { // by ID $r = $fromRow ? $fromRow : ($v ? dbRow("select * from pages where id=$v limit 1") : array() ); } else if ($byField == 1) { // by name $name = strtolower(str_replace('-', '_', $v)); $fname = 'page_by_name_' . md5($name); $r = dbRow("select * from pages where name like '" . addslashes($name) . "' limit 1"); } else if ($byField == 3 && is_numeric($v)) { // by special $fname = 'page_by_special_' . $v; $r = dbRow( "select * from pages where special&$v limit 1"); } else return false; if (!count($r || !is_array($r))) return false; if (!isset($r['id'])) $r['id'] = 0; if (!isset($r['type'])) $r['type'] = 0; if (!isset($r['special'])) $r['special'] = 0; if (!isset($r['name'])) $r['name'] = 'NO NAME SUPPLIED'; foreach ($r as $k => $v) $this->{$k} = $v; $this->urlname = $r['name']; $this->dbVals = $r; self::$instances[$this->id] = & $this; self::$instancesByName[preg_replace( '/[^a-z0-9]/', '-', strtolower($this->urlname) )] = & $this; self::$instancesBySpecial[$this->special] = & $this; if (!$this->vars) $this->vars = '{}'; $this->vars = json_decode($this->vars); } function getInstance($id = 0, $fromRow = false, $pvq = false) { if (!is_numeric($id)) return false; if (!@array_key_exists($id, self::$instances)) self::$instances[$id] = new Page($id, 0, $fromRow, $pvq); return self::$instances[$id]; } function getInstanceByName($name = '') { $name = strtolower($name); $nameIndex = preg_replace('#[^a-z0-9/]#', '-', $name); if (@array_key_exists($nameIndex, self::$instancesByName)) return self::$instancesByName[$nameIndex]; self::$instancesByName[$nameIndex] = new Page($name, 1); return self::$instancesByName[$nameIndex]; } function getInstanceBySpecial($sp = 0) { if (!is_numeric($sp)) return false; if (!@array_key_exists($sp, $instancesBySpecial)) $instancesBySpecial[$sp] = new Page($sp, 3); return $instancesBySpecial[$sp]; } } Any help is appreciated

I changed so I could see the contents of the variable $_REQUEST and I see there is an index for comments but there are some funny symbols too. I am using Mandriva Linux [â€commentsâ€]

Hi I am new to this When you have a form with various fields in them and you have given names to each field. If you submit that form then the values go sit in the array $_REQUEST am I correct? Then why do I get a index undefined? Here is the code for the form: <code> <h2> Sign my guestbook </h2> <form method="post" action="entry.php"> <b>Name:</b> <input type="text" size="40" name="name"> <br><br> <b>Location:</b> <input type="text" size="40" name="location"> <br><br> <b>Email:</b> <input type="text" size="40" name="email"> <br><br> <b>Homepage:</b> <input type="text" size="40" name="url"> <br><br> <b>Comments:</b> <textarea name=”comments” cols=”40” rows=”4” wrap=”virtualv></textarea> <br><br> <input type="submit" name="submit" value="Sign!"> <input type="reset" name="reset" value="Start over"> </form> </form> </code> Here is the code for entry.php <code> <?php include 'includes/dbconnect.php'; if($_REQUEST['submit'] == "Sign!") { $query = "insert into guestbook (name, location, email, url, comments) values ('".$_REQUEST['name']."', '".$_REQUEST['location']."', '".$_REQUEST['email']."', '".$_REQUEST['url']."', '".$_REQUEST['comments']."')"; mysql_query($query); ?> <h2>Thanks</h2> <h3><a href="view.php">View my guesbook</a></h2> <?php } else { include 'sign.php'; } ?> </code> I need to understand what happend when a form is submitted where fields have names and the method used it post. Any help is greatly appreciated Thanks

I also get the error and here is my code: <html> <head> </head> <body> <?php //Open adatabse connetcion $connect = mysql_connect("localhost", "root"); //Select db mysql_select_db("winestore",$connection); $result = mysql_query ("select * from wine", $connection); while ($row = mysql_fetch_array($result, MYSQL_NUM)) { forech ($row as $attribute) print "{$attribute}"; print /n; } ?> </body> </html> Please could you tell me what the T_AS means?

So does it mean that you cannot call variables by reference in newer version of php? Why is it deprecated? Is it abad thing or what? Any help is appreciated.

The following code gives me the error at the bottom of the page. What's wrong and how do I fix it? The book does not explain properly. Does anyone know what is the best book for learning PHP MySQL and Javascript for the web? The code: <html> <head> <title> </title> </head> <body> <pre> <?php $connection = mysql_connect("localhost", "corne", "c"); mysql_select_db("winestore", $connection); $result = mysql_query("select winery_name, phone, fax from winery limit 20", $connection); while($row = mysql_fetch_array($result)) { print "The {$row["Winery Name"]} Winery's fax is {$row["fax"]} Their phone is {$row["phone"]}. \n"; } ?> </pre> </body> </html> The Error: Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /var/www/html/testphp/database.php on line 15 Also what is MYSQ_NUM?

Nothing is shown with this code not even an error $today = date('d/m/y'); $checknow = checkdate(12, 18, 2008); if ($checknow = $today) { print "today's date is the " . $today; } else { print "Not today"; }

I get the following error Cannot redeclare count() in /var/www/html/testphp/1.php on line 14 with the code looking like this: <html> <head> <title>This whole file will be used to learn PHP and within two months.</title> </head> <body> <?php function count() { static $count = 0; $count++; return $count; } print count(); print count(); ?> </body> </html> What am I doing wrong or is the book wrong?

I have created a page in php and when I access the file I don't see anything. I then removed a faulty line and the page worked fine. How do I get the errors to show since I'm going to look forever for a mistake if the page is very long? I have turned error reporting on in php.ini but it still doesn't work. What do I do Please?

I run Mandriva linux 2008 and when I create a php file and I put it in the webroot and then navigate to it with a firefox browser nothing shows. The web server is apache and it works and it's running since it shows the famous it works page.
