Dynamically Selecting Default Option on a Dropdown Menu

[jeepguy_1980]

I modified the sort cell in a theme I picked up from DaMysterious. I made it into a drop down menu so that the text wouldn't run off of the top of the table.  I would like to know how I can setup my drop down menu to automatically select the default sort order that I have in my CPG configuration.

Thank you.

if (!isset($template_thumb_view_title_row)) { //{THEMES}
$template_thumb_view_title_row = <<<EOT

I changed it to this for now:

$template_thumb_view_title_row = <<<EOT

                                <td><img src="images/spacer.gif" width="1" alt="" /></td>
                                <td class="sortorder_cell">

Perform a check against $CONFIG['default_sort_order']
Don't forget to make that array global first inside a function.
Are you actually populating the placeholder tokens in theme_display_thumbnails() or is above code just wishfull thinking?

Thanks, I'll give that a try.

The code works exactly as I hoped.  See here: www.loopfamily.net/CPG/  You can see it work on any gallery.

Works as expected, thanks. Looks promising - you might consider to post your entire mod for the benefit of others.

That is my entire mod, with the exception of a slight change I made to the stylesheet.css to get the drop down menu to line up a bit cleaner.

I have never written anything in PHP and don't know anything about it.  I am willing to post this mod to help others, but I would first like to make it display the sorting order used (i.e. the default sort order).

I have tried using the following code to display the the default sort order, but it's not working.

<form name="sort">
$sortarr = Array("ta","td","na","nd","da","dd","pa","pd");
$i = 1;
echo "<select name=\"sortbox\" size=1 OnChange=\"location.href=sort.sortbox.options[selectedIndex].value\">";
while($i !=  8){
     $r = mysql_fetch_array($CONFIG['default_sort_order']);
     if($r['default_sort_order'] == $sortarr[$i]){
          $selected = "selected";
            }
     else{
          $selected = "";
            }
     echo "<option value=\"thumbnails.php?album={AID}&amp;page={PAGE}&amp;sort=.$sortarr[$i].\" ".$selected.">".$sortarr[$i]."</option>";
     $i++
     }
     echo "</selected>";
</form>


[Joachim Müller]

It can not possibly work because it contains syntax errors - you're mixing HTML and PHP, which is something you can't do. Haven't looked at your code, but

Code Select Expand

echo '<form name="sort">';
$sortarr = Array("ta","td","na","nd","da","dd","pa","pd");
$i = 1;
echo "<select name=\"sortbox\" size=1 OnChange=\"location.href=sort.sortbox.options[selectedIndex].value\">";
while($i !=  8){
     $r = mysql_fetch_array($CONFIG['default_sort_order']);
     if($r['default_sort_order'] == $sortarr[$i]){
          $selected = "selected";
            }
     else{
          $selected = "";
            }
     echo "<option value=\"thumbnails.php?album={AID}&amp;page={PAGE}&amp;sort=.$sortarr[$i].\" ".$selected.">".$sortarr[$i]."</option>";
     $i++
     }
     echo "</selected>";
echo '</form>';should at least stop the syntax errors. Please post the entire code, not just snippets.
