PHP - Php Code Use From Mysql Database
I'm trying to use php code that is stored in the sql database, but It doesn't seem to be executing the code. when I see the page source, its there but the server is not executing the command how do I accomplish this.
Here is a simple code snippet to show what I am trying to do. $result = mysql_query("select * from data"); $row = mysql_fetch_array($result); echo $row['code']; In the code field in data table this is whats there. <?php echo "testing."; ?> Similar Tutorialsthe below code as I understand should insert a new record into my database, but it's not. <?php $notes = $_POST['notes']; $cnamedb = $_POST['cname']; $username = $_SESSION['username']; mysql_query("INSERT INTO `ccccomma_eve`.`corps` (`id`, `name`, `ticker`, `alliance`, `ceo`, `tax`, `members`, `hq`, `apidate`, `notes`, `notedate`, `updatedby`) VALUES ('', '$cnamedb', '', '', '', '', '', '', '', '$notes', NOW(), '$username'"); echo $cnamedb." Updated"; ?> Any ideas why? Code: [Select] <?php require "db/config.php"; $fname = $_POST['fname']; $lname = $_POST['lname']; $country = $_POST['country']; $state = $_POST['state']; $city = $_POST['city']; $zcode = $_POST['zcode']; $address = $_POST['address']; $ppemail = $_POST['ppemail']; $pnumber = $_POST['pnumber']; $cemail = $_POST['cemail']; $url = $_POST['url']; $price = "$5.00"; $query = "INSERT INTO custpackage1000( id, FirstName, LastName, Country, State, City, ZipCode, Address, PayPalEmail, PhoneNumber, PrimaryEmail, WebsiteURL) VALUES ( '1', '$fname', '$lname', '$country', '$state', '$city', '$zcode', '$ppemail', '$pnumber', '$cemail', '$url')"; mysql_connect($host, $user, $pass) or die("<br /><br /><h1>Fatal error. Please contact support if this persists.</h1>"); mysql_select_db($dbname); mysql_query($query) or die ("could not open db".mysql_error()); sleep(2); ?> Why won't the code insert into my database upon submission of data? What am I doing wrong? Hi! I was wondering if there is a way to execute php code which is stored in mysql database using php. At the minute I am using a echo to try and run php code stored in a mysql database but this just displays the code and does not run the php code. Thanks for any help! I am working on a kind of CMS for my own website which no one else will be using but me as a way of improving my php skills, and am having problems with retrieving data from the database that holds both text and php code. I have searched the web and found that i should be using eval() for the code to be executed before it is send to the browser but cannot get it to work and can't find my mistake(s). the php code will always be the same, and is supposed to retrieve the id number of a page to use in a link (and works fine when tested by loading the code directly without retrieving it from the database) this is an example of data stored in the database Code: [Select] The <a href="page_builder.php?id=<?php echo $page->id('mines_DwarvenMines') ?>">Dwarven Mines</a> have a great selection of Ores,... Of course when I leave it like this, hovering over the link in my page will show exactly that and lead to nowhere Code: [Select] localhost/page_builder.php?id=<?php echo $page->id('mines_DwarvenMines') ?> Most of these links appear in tips given at the end of the page and are processed as followed Code: [Select] $questtips = $quest->getQuestTips(); $tips = ""; if ($questtips == "none") { $tips = "/"; } else { foreach($questtips as $tip) { $tips .= "<li>"; $tips .= $tip->getTip(); $tips .= "</li>"; } } and finally put on screen by the presentation layer as followed Code: [Select] <h2>Tips & Extra Info</h2> <div class="tipsList"> <ul> <?php echo $tips ?> </ul> </div> I have tried all sorts to get the code to be executed when retrieved from the database before being send to the browser so that this particular link would say "localhost/page_builder.php?id=57" but I cannot get it to work, though I suspect it is fairly easy. I suspect I would have to store the data in a different format in the database? And how exactly do I use the eval() function in my case? Could someone please adjust my code so that it does work? Thanks I've been playing around with this code from http://v3.thewatchmakerproject.com/journal/276/building-a-simple-php-shopping-cart Objective: I'm trying to make the scripts work but without pulling the data from MySQL Database. Instead, I created an array and inserted some info there and trying to replicate the same results but getting confused. For example, on the Index.php file, I made the following changes: <?php // Start the session session_start(); // Include functions require_once('inc/functions.inc.php'); // Products multidimensional Array $products = array("book" => array( 'id' => '1', 'title' => 'Learn Your ABC\'s', 'author' => 'John Doe', 'price' => '14.95'), "video" => array('id' => '2', 'title' => 'Visual Guide to learn', 'author' => 'Adam Smith', 'price' => '21.38'), "puzzle" => array('id' => '3', 'title' => 'Can You Solve?', 'author' => 'Sara Brown', 'price' => '9.41'), "exam" => array('id' => '4', 'title' => 'Test Your Knowledge', 'author' => 'Kim Carver', 'price' => '11.15')); ?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>PHP Shopping Cart Demo &#0183; Bookshop</title> <link rel="stylesheet" href="css/styles.css" /> </head> <body> <div id="shoppingcart"> <h1>Your Shopping Cart</h1> <?php echo writeShoppingCart(); ?> </div> <div id="booklist"> <h1>Books In Our Store</h1> <?php /* $sql = 'SELECT * FROM books ORDER BY id'; $result = $db->query($sql); $output[] = '<ul>'; while ($row = $result->fetch()) { $output[] = '<li>"'.$row['title'].'" by '.$row['author'].': $'.$row['price'].'<br /><a href="cart.php?action=add&id='.$row['id'].'">Add to cart</a></li>'; } $output[] = '</ul>'; echo join('',$output); */ ?> <?php $output[] = '<ul>'; foreach ($products as $product => $product_item) { // $flavor is the key and $piece is the value foreach ($product_item as $item => $piece) { if ($item == "id") { # Conditional logic defined to map specific keys to specified name value $row['id'] = $piece; // echo "The id is ". $id."<br />"; // set just to confirm value correct for variable } elseif ($item == "title") { # Conditional logic defined to map 1st key to price value $row['title'] = $piece; // echo "The title is ". $title."<br />"; // set just to confirm value correct for variable } elseif ($item == "author") { # Conditional logic defined to map 1st key to price value $row['author'] = $piece; // echo "The author is ". $author."<br />"; // set just to confirm value correct for variable } elseif ($item == "price") { # Conditional logic defined to map 1st key to shipping value $row['price'] = $piece; // echo "Price: ". $price."<br /><br />"; // set just to confirm value correct for variable } $output[] = '<li>"'.$row['title'].'" by '.$row['author'].': $'.$row['price'].'<br /><a href="cart.php?action=add&id='.$row['id'].'">Add to cart</a></li>'; $output[] = '</ul>'; echo join('',$output); } } ?> </div> </body> </html> And here's the original index.php before my edits which show the sql query to the db: <?php // Include MySQL class require_once('inc/mysql.class.php'); // Include database connection require_once('inc/global.inc.php'); // Include functions require_once('inc/functions.inc.php'); // Start the session session_start(); ?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>PHP Shopping Cart Demo &#0183; Bookshop</title> <link rel="stylesheet" href="css/styles.css" /> </head> <body> <div id="shoppingcart"> <h1>Your Shopping Cart</h1> <?php echo writeShoppingCart(); ?> </div> <div id="booklist"> <h1>Books In Our Store</h1> <?php $sql = 'SELECT * FROM books ORDER BY id'; $result = $db->query($sql); $output[] = '<ul>'; while ($row = $result->fetch()) { $output[] = '<li>"'.$row['title'].'" by '.$row['author'].': £'.$row['price'].'<br /><a href="cart.php?action=add&id='.$row['id'].'">Add to cart</a></li>'; } $output[] = '</ul>'; echo join('',$output); ?> </div> </body> </html> Also, I included the zipped file of the entire script setup. Again, I'm trying to figure out how to make the cart work with using an array for the product instead of MySQL database. My goal is to remove ALL SQL statements from the scripts but stuck with the looping portion to display the title, author, and price from the array as shown above. At the moment I am creating a search function for my website. The approach I have in mind is a pseudo-PHP database. To give an example: A HTML form will submit the results to a PHP file. HTML FORM - Colour: Black PHP RESULT PAGE - if ($_POST['color'] == 'Black') {readfile("./products/black/*.html");} HTML FORM - Price: <$50 PHP RESULT PAGE - if ($_POST['Price'] == '<$50') {readfile("./products/less50/*.html");} The problem here is if there is an item that is black and costs less than $50, then its going to be listed twice. There is probably some code I can write to ommit the listing of duplicate entries, but it is probably going to be messy, so I am wondering if its better to use a centralized MySQL database, rather than a pseudo-PHP database? I've never used MySQL and don't know much about it and this is my first real attempt at using PHP. Advance thank you. Can you help please. The error..... Warning: mysql_fetch_assoc() expects parameter 1 to be resource, string given in C:\wamp\www\test_dabase.php on line 24 code.

What is the best way to get the information from CSV into this database? Should I have another table and store the CSV data as is and then query that to make the other tables. Any help much appreciated. Hi All, Whenever I try to update any piece of PHP code to update a MySQL database, nothing happens. I have tried copying in some of the working codes of a website and tried the same, but no success. I recently installed XAMPP. I am connecting using the correct user id and pass to the database. The scripts are not giving me any error, but just not connecting, that's all. While making such a usage as noted below <FORM name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" > I get the following error Firefox can't find the file at /C:/xampp/htdocs/="<?php.. so on Why does this happen? I am pretty new to this, so please do help. Thanks, Satheesh P R Hello all, first post here so i hope i'm doing this right and am putting this into the right place. Im in the process of integrating a blog into my website, mostly it's set up however i'm currently working on the code to update the posts (theres only 2 parts a title and a comments[which is in actual fact the post content itself]). The code succsefully completes without any errors but for some reason it does not actually update the mysql database.. the code i'm using is as follows: Code: [Select] <?php require_once('header.php'); include "../blog/blogconfig.php"; if(isset($_POST['submit'])){ $update="UPDATE eq_blogarticle SET title='".$_POST['title']."',comments='".$_POST['comment']."' WHERE artid='$aid'"; if(!mysql_query($update)){ echo mysql_error(); }else{ header("location:blog.php?action=listmsgs"); exit; } } ?> <?php // get value of aid that sent from address bar by blog.php?action=listmsgs $aid=$_GET['aid']; // Retrieve data from database $sql="SELECT * FROM eq_blogarticle WHERE artid='$aid'"; $result=mysql_query($sql); $row=mysql_fetch_array($result); ?> <form name="form2" method="post" action="update.php"> <script type="text/javascript">var SITE_URL="<?php echo SITE_URL;?>";</script> <script type="text/javascript" src="<?php echo SITE_URL;?>/includes/js/nicEdit.js"></script> <script type="text/javascript"> //<![CDATA[ bkLib.onDomLoaded(function() { nicEditors.allTextAreas() }); //]]> </script> <body> <table width="100%" border="0" cellspacing="1"> <tr> <td colspan="2" class="temptitle">Equidisc Blog</td> </tr> <tr> <td width="74%" valign="top"> <table> Edit Blog Post <br> <br> Title: <br> <input name="title" type="text" class="input" id="title" value="<? echo $row['title']; ?>"> <br> <br> <span class="style1 style2 style3">Blog Post:</span> <br> <br> <textarea name="comments" cols="55" rows="12" class="input" id="comments"><? echo stripslashes($row['comments']); ?></textarea> <br> <br> <input name="aid" type="hidden" id="aid" value="<? echo $row['artid']; ?>"> <input type="submit" name="submit" value="Submit"> </form> </table> </td> <td width="26%" valign="top"><table width="100%" border="0" cellspacing="1"> <tr> <td colspan="2"><img src="../blog/images/fb.gif" width="16" height="16" /> <strong>Blog Menu</strong></td> </tr> <tr> <td><a href="blog.php">Home</a></td> </tr> <tr> <td><a href="blog.php?action=newblogpost">New Post </a></td> </tr> <tr> <td><a href="blog.php?action=listmsgs">Manage Posts </a></td> </tr> </table></td> </tr> </table> </body> <?php require_once('footer.php'); ?> Explanation: header/footer.php obvious ../blog/blogconfig.php holds my mysql connection settings and connects to the sql, this is the same config as is used for creating the new posts which i have no issues with so i dont think the issue lays there. If i run the query on phpmyadmin with dummy data it works fine and updates the entry.. Any help would be very much appreciated as i'm at the end of my tether with this!. Thanks in advance. Jo I know this is a very simple and probably stupid question - but what is a patch? i've tried searching online for an explanation but I just find articles on the 'best practice' and it doesn't break it down into what it actually is!
I've just been looking into new hosting and they offer a managed service, which includes database patching.
Could someone please enlighten me?
Edited by paddyfields, 10 June 2014 - 04:49 AM. Hey guys, I'm working a project that requires sessions be stored within the database, as the project I'm working on is on a shared host. But I'm having a problem with getting the data of a session in the database, the other fields like session_id, session_updated, session_created are working fine. I think I've got a bug in my code, but I just can't detect it (frustrating). Database connection class db extends mysqli { private $host; private $user; private $pass; private $db; function __construct( $host='localhost', $user='user', $pass='pass', $db='website' ) { $this -> host = $host; $this -> user = $user; $this -> pass = $pass; $this -> db = $db; parent::connect( $host, $user, $pass, $db ); if( mysqli_connect_error( ) ) { die( 'Connection error ('.mysqli_connect_errno( ).'): '.mysqli_connect_error( ) ); } } function __destruct( ) { $this -> close( ); } } Session handler class sessionHandler { private $database; private $dirName; private $sessTable; private $fieldArray; function sessionHandler() { // save directory name of current script $this -> database = new db; $this -> dirName = dirname(__file__); $this -> sessTable = 'sessions'; } function open( $save_path, $session_name ) { return TRUE; } function close() { //close the session. if ( !empty( $this -> fieldarray ) ) { // perform garbage collection $result = $this->gc( ini_get ( 'session.gc_maxlifetime' ) ); return $result; } return TRUE; } function read( $session_id ) { $sql = " SELECT * FROM sessions WHERE session_id=( '$session_id' ) LIMIT 1 "; $result = $this -> database -> query( $sql ); if( $result -> num_rows > 0 ) { $data = $result -> fetch_array( MYSQLI_ASSOC ); $this -> fieldArray = $data; $result -> close(); return $data; } return ""; } function write( $session_id, $session_data ) { //write session data to the database. if ( !empty( $this -> fieldArray ) ) { if ( $this -> fieldArray['session_id'] != $session_id ) { // user is starting a new session with previous data $this -> fieldArray = array(); } } $this -> fieldArray['session_id'] = $session_id; $this -> fieldArray['session_data'] = $session_data; $this -> fieldArray['session_updated'] = time(); $this -> fieldArray['session_created'] = time(); $session_id = $this -> database -> escape_string( $session_id ); $session_data = $this -> database -> escape_string( $session_data ); $session_updated = time(); $session_created = time(); $sql = " INSERT INTO sessions ( session_id, session_data, session_updated, session_created ) VALUES ( '$session_id', '$session_data', '$session_updated', '$session_created' ) "; if( $this -> database -> query( $sql ) !== TRUE ) { return FALSE; } return TRUE; } function destroy( $session_id ) { $sql = " DELETE FROM sessions WHERE session_id=('$session_id') "; if( $this -> database -> query( $sql ) !== TRUE ) { return FALSE; } return TRUE; } function gc( $max_lifetime ) { return TRUE; } function __destruct() { //ensure session data is written out before classes are destroyed //(see http://bugs.php.net/bug.php?id=33772 for details) @session_write_close(); } } The call $session_class = new sessionHandler; session_set_save_handler( array( &$session_class, 'open' ), array( &$session_class, 'close' ), array( &$session_class, 'read' ), array( &$session_class, 'write' ), array( &$session_class, 'destroy' ), array( &$session_class, 'gc' ) ); if( !session_start() ) { exit(); } Any help at all would be appreciated. Kind Regards Mike Okay, I have been following this tutorial: http://www.freewebmasterhelp.com/tutorials/phpmysql/1 to achieve exactly what I wanted to get done. I also followed the way to have it formatted in tables and added extra columns that I needed, included an "Options" column which houses three links, including "edit" and "delete" Now, I have everything working fine but I am stumped on how to get the "edit" and "delete" links to work for each individual entry that is listed. I have to have these features so the entries can be edited and deleted without having to physically go into the MySQL database to do it. The tutorial explains how to do it in Step 6, but I am confused. I'm not quite sure where to place the code for the links, which are generated automatically every time a new entry is inputted into the database. Anybody available to help me out? Thanks! Hi there, I have been creating a website which shows products of the companys (www.theadventurestartshere.org) and I have been trying to make some filters for the products using URL Parameters and recordsheet filters... Can someone advise me on the easiest way to do this? As I have created a method to do it with, (check website) but it has to be entered manually and I was hoping there is an easier way? Please Note I like to use drop down boxes for the filters but if there is a way to do the checkbox style you see on say Amazon then that would be brilliant... I use Dreamweaver CS5, and the newest versions of PHP and MySql Many Thanks, Paul There is a "PHP ajax cascading dropdown using MySql" at codestips.com/php-ajax-cascading-dropdown-using-mysql/ I want to use this technique but with a XML or array file instead of mysql database, but my knowledge about mysql is very low. How I can modify this code to catch the categories and products from an array, instead of mysql database?

Hi, I wonder if you could help me try to find what i'm looking for, i have a problem with bogus users on my site. I created a register page where the details are sent to the database, this is fine but someone is registering with the username: 1 and password: 1 multiple times. I have about 50 of these now and i would like to know what to actually search for (how to word it) to find out how to stop this? What would be the name of the script? i've looked for fake username script, multiple username/password prevention script, i'm just not getting it, sorry. If any of you have any ideas i'd like to hear from you, many thanks in advance for that. If you need anymore to go on please ask, once again thank you. Hi On my xampp server's database I get the warning that my database is read-only when I try to insert something into a table. I think I may know what cause this, because I created an export/import app that exports/import important data to the database... How can I remove the read-only from the database, because I am scared that the same thing might happen to my server's database? And is there a mysql query that test if the database is read-only? Thanks in advance I looked into this everywhere,but the code does not make sense, is not properly documented and is outdated. Ive been trying to achieve this for the past hour. Anybody know how I can do this? |
