    <h2>This is likely an easy fix (easy +200 reputation), for someone who has javascript skills.</h2> <h2>Demo of problem: <a href="http://shoppingcart-bthub.blogspot.com/" rel="nofollow">http://shoppingcart-bthub.blogspot.com/</a> Just add all the items to the cart and click refresh to see the problem with the cookies.</h2> <p>Everything works correctly, except the part of the code that handles cookies for the items that get added to the shopping cart. For some reason, it only holds 2 -5 items, depending on the broswer:</p> <p>Google Chrome - only holds 2 items (all other items in shopping cart disappear after page reload)</p> <p>Firefox - 4 items total</p> <p>Safari - 4</p> <p>Internet Exploer - 5</p> <p>The javascript in the demo: <a href="http://shopppingcart.googlecode.com/files/simplecart.js" rel="nofollow">http://shopppingcart.googlecode.com/files/simplecart.js</a></p> <p>The part of the javascript link above that is coded to handle cookies:</p> <pre><code> /*** data storage and retrival ****/ /* load cart from cookie */ me.load = function () { var me = this; /* initialize variables and items array */ me.items = {}; me.total = 0.00; me.quantity = 0; /* retrieve item data from cookie */ if( readCookie('simpleCart') ){ var data = unescape(readCookie('simpleCart')).split('++'); for(var x=0, xlen=data.length;x&lt;xlen;x++){ var info = data[x].split('||'); var newItem = new CartItem(); if( newItem.parseValuesFromArray( info ) ){ newItem.checkQuantityAndPrice(); /* store the new item in the cart */ me.items[newItem.id] = newItem; } } } me.isLoaded = true; }; /* save cart to cookie */ me.save = function () { var dataString = ""; for( var item in this.items ){ dataString = dataString + "++" + this.items[item].print(); } createCookie('simpleCart', dataString.substring( 2 ), 30 ); }; </code></pre> <h2>To test the full live code:</h2> <p>For the complete live template with all the codes, open a free blog at blogger.com and download the XML template here to upload into blogger: <a href="http://www.bloggermint.com/2011/05/shopping-cart-blogger-template/" rel="nofollow">http://www.bloggermint.com/2011/05/shopping-cart-blogger-template/</a> The free download is in the left-hand sidebar.

    1. COHi Loop, I have just tested the simplecart.js (the first one) both in IE10 and Chrome. Seems I cannot reproduce your bug. I created 10 items with looong names, and added 10 units of each item to cart. My simplecart cookie is 1136 bytes length. I suggest 2 things: 1. Validate you have no cookie limitations/permission issues, 2. share your html/js, maybe the bug is in your code.

    2. COA demo of the shopping cart that I am using can be found here: http://shoppingcart-bthub.blogspot.in/ Everything on the page .js and HTML wise is the exact same as on my site. The bug is the same on this site too. Just add all the items and click refresh and you will see the bug.

    3. COI would love to post all the HTML with it in my post but because it is in the blogger.com platform, it's extremely huge. Hopefully the view source and inspect elments of that demo site will help narrow down the bug that I am getting. Anything else you need, please let me know.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
