PHP - Trying To Convert Code To Use Arrays Instead Of Mysql Database For Items
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. Similar TutorialsI coded the following but some parts are not working (the "curveball" mentioned at the end). How would YOU do this? I have a page (A) displaying a form with a textarea field using a WYSIWYG interface. The user will enter a list of unordered items and upon submit the string will look something like this: This is my list of food items: <ul> <li> Lettuce </li> <li> Tomatoes </li> <li> Eggs </li> <ul> Upon submit, I need to give each list item an unique id and store this id along with the text next to it in a separate table: List_item_id List_item_text List_item_state food_1 Lettuce food_2 Tomatoes food_3 Eggs The user will then land in another page with a form displaying the list. The text is now in the page itself and not in a textarea. Instead of the bullets a dropdown list appears, and the user can select "buy" or "sell" for each list item. This page (B) looks something like this: <form> This is my list of food items: <br><select name="food_1"> <option value="buy">Buy</option> <option value="sell">Sell</option> </select> Lettuce <br><select name="food_2"> <option value="buy">Buy</option> <option value="sell">Sell</option> </select> Tomatoes <br><select name="food_2"> <option value="buy">Buy</option> <option value="sell">Sell</option> </select> Eggs <input type=submit value="submit"> </form> When the user hits "submit" the table with the list items will be updated with the values selected in the dropdown list: List_item_id List_item_text List_item_state food_1 Lettuce Buy food_2 Tomatoes Buy food_3 Eggs Sell The next time the user goes to Page B the list will remember the states. Here's the curveball: At any point the user may click on "EDIT LIST" on Page B so they may add more items (at the begining, middle or end of the string). On edit mode the list items should appear as bullets again inside the WYSIWYG interface. Keep in mind that some of the text in the string may not be a list item (ie, "this is my list of food...") I have a webpage where all the database items are displyes in a table format.The table also has a check box.Upon clicking the delete button i need to delete all the items whish has the checkbox checked. How will i do that 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."; ?> the 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? 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 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?

While displaying it is in this format---Topic Heading,Belongs to which all categories,date posted and the description. All this are taken from database. Now my actual issue is I am not able to give links to the categories dispalyed ,if the category exceeds more than 1. For eg: Global Warming Posted on March 11,2011 in News, Issue -----------description of global warming goes here. In the above eg: News and issue are the two categories,when i click on News it should display all the items in news category,and when i click on issue it should display all items of issue category.

Does anyone know of a function or can give me an example on how i can do this. I'm trying to make it so that someone can add an item to the shop based upon the current items within the database. How do I go about doing that? I know i have to change <input> to <select>, but beyond that, how do I code it so I can run an array to get all the current items from the table `items` and list them by their `name` field?

I have a list of available cars in a MySQL database. I'm just not sure how to get php to generate a list of, say, 20 cars, that are randomly picked from the cars in the database. I may also want to add other statistics like MPG (also already in the database). Can anyone show me how to do this? And is it possible to format the returned data in a table or div format? Thanks in advance Unk This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=334480.0 This is probably some obvious error I have made, but I cannot figure it out. I have made a few pages and now I am debugging them. My first page is called insert_purchase_order.php; on this page a person will enter some data in fields and hit the insert button. Then, the data is passed to another page, but when I try to insert into mysql it does not give me any errors, but I have no new rows either. The code for my 2nd page: Code: [Select] <?php session_start(); $action=$_GET[action]; if ($action==insert){ $randid=$_POST['randid']; $vendor=$_POST["vendor"]; $purchase_order_date=$_POST["purchase_order_date"]; $ship=$_POST["ship"]; $fob=$_POST["fob"]; $terms=$_POST["terms"]; $buyer=$_POST["buyer"]; $freight=$_POST["freight"]; $req_date=$_POST["req_date"]; $confirming_to=$_POST["confirming_to"]; $remarks=$_POST["remarks"]; $tax=$_POST["tax"]; $con = mysql_connect("localhost","root","pass"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("main", $con); mysql_query("INSERT INTO purchase_order (randid, vendor, purchase_order, ship, fob, terms, buyer, freight, req_date, confirming_to, remarks, tax) VALUES ($randid, $vendor,$purchase_order_date,$ship, $fob, $terms, $buyer, $freight, $req_date, $confirming_to, $remarks, $tax)"); mysql_close($con); echo 'Data Accepted...'; echo '<br/>'; echo 'P.O.

Thanks Hello, In my Mysql database, it has a datetime field. and I have created a $today = date('Y-m-d H:i:s'); <- today's date and time How do I write a query to run in PHP in order to get all today's items by comparing datetime field and $today? Thanks! I currently have a page where I have each row in my table listed using: Code: [Select] $getinfo="SELECT * FROM tablename WHERE Closed='n'"; $result=mysql_query($getinfo); while ($row=mysql_fetch_array($result)){ ... // list of user information } That successfully displays my content. What I am trying to do is have a checkbox next to each user (row) that when I check them and hit submit at the bottom, it will change the value of each row on the 'Closed' column to 'y' so it will not be displayed when the page is refreshed. I want to be able to select multiple items to "close". And I would like it to come back to this page. I think I can use this page as the form action and have the code above my while loop to change the Closed column so it then would not be displayed when the while loop is called... is that right? How do I set this up? Not sure where to start the form tag and where to end it, and not sure how to...well...do any of it. Hi, i have 2 currencies in my mysql and when user add new article, he choose currency and price.
