If/Then statement to show table

Warwick · #1 06-14-2007, 11:17 AM

I'm trying to come up with an if/then statement to show search keywords (in a table) when there are keywords entered, if not then it should not show.

In my case it's a table that needs to be shown with the following code:

Code:

<table>
<tr>
<td valign="top"><img src="{$ImagesDir}/icon.gif" width="15" height="17"></td>
<td>{$lng.lbl_related_keywords} <br>{foreach from=$keywords item=keyword}<a href="_search.php?q={$keyword}">{$keyword}</a> {/foreach}<br></td>
</tr>
</table>
[b]

This is what I tried (without success):

Code:


{if $keywords ne ""}

<table>
<tr>
<td valign="top"><img src="{$ImagesDir}/icon.gif" width="15" height="17"></td>
<td>{$lng.lbl_related_keywords} <br>{foreach from=$keywords item=keyword}<a href="_search.php?q={$keyword}">{$keyword}</a> {/foreach}<br></td>
</tr>
</table>

{/if}

Can anybody help me with this?

Thanks in advance!

try

{if $keywords}

You didn't say what is in the $keywords variable. Array? List? Text? An example of the contents would be nice.

The keywords reffer to the search keywords in X-Cart 4.1.3, so that would be text right?

Hi Warwick!

Please, edit the <xcart_dir>/include/search.php script and replace:

PHP Code:


		
			
if (!$_inner_search)

    $smarty->assign("search_prefilled", $search_data["products"]);

with

PHP Code:


		
			
if (!$_inner_search)

    $smarty->assign("search_prefilled", $search_data["products"]);



    if (!empty($search_data["products"]["substring"])) {

        $keywords = explode(" ",$search_data["products"]["substring"]);

        $keywords = func_array_map("trim", $keywords);



        if (is_array($keywords)) {

            foreach($keywords as $i=>$k)

                if (empty($k))

                    unset($keywords[$i]);

            $keywords = array_values($keywords);

        }

        $smarty->assign("keywords", $keywords);

    }

After that you'll be able to use the {$keywords} Smarty variable in your templates.

Thanks Eugene!

I have implemented your modification and tried the following statements then but both don't work (yet); forgive me for being such newbie; I must be doing something very stupid.

Code:

{if $keywords}
<table>
		 <tr>
    <td valign="top"><img src="{$ImagesDir}/keywords_small_icon.gif" width="15" [color=red][b]height="17"></td>
 <td>{$lng.lbl_related_keywords} <br>{foreach from=$keywords item=keyword}<a href="_search.php?q={$keyword}">{$keyword}</a> {/foreach}<br></td>
  </tr>
  </table>
{/if}

and

Code:

{if $keywords ne ""}
<table>
		 <tr>
    <td valign="top"><img src="{$ImagesDir}/keywords_small_icon.gif" width="15" height="17"></td>
 <td>{$lng.lbl_related_keywords} <br>{foreach from=$keywords item=keyword}<a href="_search.php?q={$keyword}">{$keyword}</a> {/foreach}<br></td>
  </tr>
  </table>
{/if}

Please add the following code to a necessary template(at the very beginning):

Code:

{$keywords|print_r}

then refresh the page(or search for any keywrods), do you see any debug info?

I have implemented the code you mentioned in the product template without any if/then statement and get: balancerailArray
(the 'balancerail' being the product name)

try using {if !empty($keywords)}{/if}

Thanks inebriate but this doesn't work either
