Hello,

I have created several fields with CCK that I have added to the add new product page. I now have about 40 additional fields that contain information about my products. Each product only uses about 10 of those fields, so there are several that are blank depending on the product. I would like to create a "Specifications" table on the product page that will show all of the variables that have a value assigned to them for that product.
Here is an example of the layout with the "Specifications" table.
http://www.xikar.com/redesign/Final_Site/Xi1_individual_product_page.pdf

Is it possible to use TAPIr to create this table? Does is have the ability to only show the fields that have a value in them? Is there a better way to do this?

Here is an example of an array that contains the data:

[group_general] => Array
                (
                    [field_style] => Array
                        (

How do I go about assigning this array to a TAPIr table and then only outputting the fields that have a value?

Thanks for any help you can give me.

I figured out how to access the elements of the array that i need with this:

<?php
foreach(array_keys($node->content['group_general']) as $key){
    print $node->content['group_general'][$key]['#value'];
     }
if(isset($node->content['group_cutter_specific'])){
     foreach(array_keys($node->content['group_cutter_specific']) as $key) {
     print $node->content['group_cutter_specific'][$key]['#value'];
     }
}
if(isset($node->content['group_lighter_specific'])){
     foreach(array_keys($node->content['group_lighter_specific']) as $key) {
     print $node->content['group_lighter_specific'][$key]['#value'];
     }
}
if(isset($node->content['group_punch_specific'])){
     foreach(array_keys($node->content['group_punch_specific']) as $key) {
     print $node->content['group_punch_specific'][$key]['#value'];
     }
}
if(isset($node->content['group_knife_specific'])){
     foreach(array_keys($node->content['group_knife_specific']) as $key) {
     print $node->content['group_knife_specific'][$key]['#value'];
     }
}
if(isset($node->content['group_humidification_specific'])){
     foreach(array_keys($node->content['group_humidification_specific']) as $key) {
     print $node->content['group_humidification_specific'][$key]['#value'];
     }
}
if(isset($node->content['group_cases_and_humidors'])){
     foreach(array_keys($node->content['group_cases_and_humidors']) as $key) {
     print $node->content['group_cases_and_humidors'][$key]['#value'];
     }
}
if(isset($node->content['group_appearl'])){
     foreach(array_keys($node->content['group_appearl']) as $key) {
     print $node->content['group_appearl'][$key]['#value'];
     }
}
?>

I'm trying to simplify it into this:

<?php

    foreach(array_keys($node->content) as $key){
        if(isset($node->content[$key])){
            foreach(array_keys($node->content[$key]) as $specifications){
                print $node->content[$key][$specifications]['#value'];
            }
        }
    }
?>

For some reason I get an error with the simplified version.
* warning: array_keys() [function.array-keys]: The first argument should be an array in C:\WAMP Server\wamp\www\themes\xikar\node-product.tpl.php on line 29.
* warning: Invalid argument supplied for foreach() in C:\WAMP Server\wamp\www\themes\xikar\node-product.tpl.php on line 29.

* warning: Invalid argument supplied for foreach() in C:\WAMP Server\wamp\www\themes\xikar\node-product.tpl.php on line 29.

Any idea why the simplified version causes these errors? It still prints out, but I get the above errors.

I'm also getting some random characters in the printed code like the "<", "<3" and "2" in bold below.

$node->content contains all the stuff that is displayed when the node is viewed, not just the CCK fields. Some things might not be arrays like your code expects, so that's why you get the errors.

Put

<?php
  print '<pre>';
  print_r($node->content);
  print '</pre>';
?>

in your template file to get a good look at what you're dealing with.

From your examples, you might be able to test the keys of the content array to get the parts you want:

<?php
// Use element_children() to ignore keys like '#weight'.
foreach (element_children($node->content) as $key){
  if (substr($key, 0, 6) == 'group_'){
    foreach (element_children($node->content[$key]) as $specifications){
      // Work, work...
    }
  }
}
?>

Thanks Lyle, that worked perfect! I started debugging by added echo $key; everywhere and realized I needed to only access the keys that had "group_" in them. However, I still couldn't find the right function to check if 'group_' was in the key.

It's hard to theme things when your a PHP noob, but I'm learning fast.
