Product details page doesn't show

**tacoma** · 4 Feb 2008, 11:46 PM

The products list normally. But when a product is selected the page just shows the left menu, the 'next' - 'previous' buttons, and doesn't show the product information or pictures.

I'm using 1.3.8 Zen Cart.

What would be the area that controls that? I've gone over the tpl_product_info_display.php file vs. the original, and they are the same.

You would also need top look at the modules/pages/products_info folder and check the files there. But why not give us a link to the site, there may well be clues there that you may be overlooking?

Although your product info page isn't blank, it does stop dead. This may well mean that there is a PHP error that is being suppressed. As a first step I would recommend installing the debug facility referred to in this FAQ Entry. And then taking a look at the error log that it produces to see if there is an obvious error being reported (if there is it will probably tell you the exact file and line number where the error is occurring).

No error log to check.

It was working earlier today, all I did was upload some images.

Were they unusually large images? Where they RGB rather than CMYK images? It seems that your site enters the main images module, but never comes out the other site.

The images were replacements of previously larger versions. I just uploaded opimized versions.

It's very rare that code just stops without returning a PHP or SQL error. I've only seen it once. If the debug mod isn't generating an error log, then you would need to go after it line by line.

You know from the comment lines generated that you go into the main image template module, so you either needed a debugging tool that allows you to step through the code line by line to see where it fails, or insert echo statements by hand to track it down. Once you find the point of failure, the reason is usually not difficult to work out.

Using Firebug this is what I see.

PHP Code:


<html lang="en" dir="ltr" xmlns="http://www.w3.org/1999/xhtml">

<head>

</head>

<body id="productinfoBody">

<div id="mainWrapper">

<div class="messageStackWarning larger">

</div>

<div id="headerWrapper">

</div>

<table id="contentMainWrapper" width="100%" cellspacing="0" cellpadding="0" border="0">

<tbody>

<tr>

<td id="navColumnOne" class="columnLeft" style="width: 150px;">

</td>

<td valign="top">

<div id="productGeneral" class="centerColumn">

<form enctype="multipart/form-data" method="post" action="http://website/zencart/index.php?main_page=product_info&cPath=3_20&products_id=13&action=add_product" name="cart_quantity">

<div id="categoryIcon" class="categoryIcon" align="left">

<a href="http://website/zencart/index.php?main_page=index&cPath=3_20">3rd Member Parts</a>

</div>

<div class="navNextPrevWrapper centeredContent">

<p class="navNextPrevCounter">Product 27/27</p>

<div class="navNextPrevList">

</div>

<div class="navNextPrevList">

</div>

<div class="navNextPrevList">

</div>

</div>

</form>

</div>

</td>

</tr>

</tbody>

</table>

</div>

<div id="lbOverlay" style="visibility: hidden; opacity: 0;"/>

<div id="lbCenter" style="width: 400px; height: 300px; margin-left: -200px; display: none;">

</div>

<div id="lbBottomContainer" style="display: none;">

</div>

</body>

</html>

Isn't missing something like this.

PHP Code:


<div id="categoryIcon" class="categoryIcon" align="left">

</div>

<div class="navNextPrevWrapper centeredContent">

</div>

<div id="productMainImage" class="centeredContent back">

</div>

<h1 id="productName" class="productGeneral"></h1>

<h2 id="productPrices" class="productGeneral"></h2>

<div id="productDescription" class="productGeneral biggerText">

</div>

<br class="clearBoth"/>

<div id="cartAdd">

</div>

<ul id="productDetailsList" class="floatingBox back">

</ul>

<br class="clearBoth"/>

</form>

This is a case where firebug isn't very helpful as it shows you what the page looks like after it has been rendered by your browser, i.e. after the browser has done its best to clean up and close missing end tags.

What you really need to see is what it looks like before it makes its corrections. To do this, view the page source and you'll see that it ends rather abruptly like this ...

<div class="navNextPrevWrapper centeredContent">
<p class="navNextPrevCounter">Product 3/12</p>
<div class="navNextPrevList"><a href="http://www.YOUR_SITE.com/lamb/index.php?main_page=product_info&cPath=4_21_53&products_id=247"><img src="includes/templates/template_default/buttons/english/button_prev.gif" alt="Previous" title=" Previous " width="38" height="15" /></a></div>

<div class="navNextPrevList"><a href="http://www.YOUR_SITE.com/lamb/index.php?main_page=index&cPath=4_21_53"><img src="includes/templates/template_default/buttons/english/button_return_to_product_list.gif" alt="Return to the Product List" title=" Return to the Product List " width="47" height="15" /></a></div>

<div class="navNextPrevList"><a href="http://www.YOUR_SITE.com/lamb/index.php?main_page=product_info&cPath=4_21_53&products_id=239"><img src="includes/templates/template_default/buttons/english/button_next.gif" alt="Next" title=" Next " width="38" height="15" /></a></div>
</div>

I understand, but I can't figure out why it ends.
