Hi all,
Im quite new to using Smarty, I want to rename or modify variable content..

Here's the deal, I am dynamically displaying images from the DB, i display thumbnails and on click of the thumbnail i want it to display the bigger version of that image.

I have a naming conversion for my images, for example:
Code:

//GAL_17_1_Lighthouse --> small/thumbnail image for lighthouse
//GAL_17_2_Lighthouse --> big image  for lighthouse


notice that the last number changes, 1 for small, and 2 for a bigger version of that image... hope its clear there..

in the DB i only store the name of the thumbnail, so in my PHP file I select the name of the image
Code:

$sql=SELECT image_name
        FROM images_table;

//execute my SQL statement
$image = sqlExecute($connection, $sql, $sqlError, $sqlCount, basename(__FILE__), DEBUG);

$tmplEngine->assign(
    array(
        'thumbnails'              => $image,
  )
);


and then in my HTM file i display the thumbnail
Code:

{section name=list loop=$thumbnails}
<tr >
   <td><a href="images/{$thumbnails[list].image_name}" rel="enlargeimage" rev="targetdiv:loadarea2,trigger:click,preload:none,fx:reveal"><img src="images/{$thumbnails[list].image_name}"></a><br /></td>

</tr>
{/section}


The above code displays thumbnails as links, on click of a thumbnail it displays a thumbnail again of that image, but that is not what i want, i want it to display the bigger version, by simply modifying the HREF attribute. Is there a way to modify the value for {$thumbnails[list].image_name}? If it is not possible, can you please give me a few tips on how i can achieve this dynamically... Thank you in advance

Have a look at the replace modifer. See http://www.smarty.net/manual/en/language.modifier.replace.php

You could use it to replace '_1_' with '_2_'.

Not to dodge the question, but there is a better way to handle your situation. In PHP when you select the image name from the db, supply both the thumbnail and large image filenames in an array (or as separate variable names.) Then the template can just display the correct filename and not deal with filename assembly.
