How do I sort a custom class' selection attribute?

Wednesday 13 September 2006 8:17:24 am

I have a custom class with a multiple selection attribute named <b>Country</b>. This attribute lists several countries listed in no particular order.

This code is being used to display it as a dropdown:

<select name="study_country">
   <option value="-99" selected>Please select a country...</option>
   <option disabled>&nbsp;</option>
   {def $countries = fetch('content', 'class_attribute', hash('attribute_id', 308))}
     {foreach $countries.content.options as $dropdown_item}
        <option>{$dropdown_item.name}</option>
     {/foreach}
 </select>

This displays the countries in whatever order they are listed in the class definition. I need these to be sorted alphabetically. <b>fetch('content', 'class_attribute')</b> does not seem to allow this.

How can I accomplish this?

Thank you for the suggestion Claudia. I installed the extension and rewrote the code above like so:

 {def $country_array = array("foo")}
 {def $countries = fetch('content', 'class_attribute', hash('attribute_id', 308))}
 
 {foreach $countries.content.options as $dropdown_item}
   {set $country_array = $country_array|append($dropdown_item.name)} 	
 {/foreach}
 
 {set $country_array = $country_array|remove(0,1)}
 {def $sorted_country_array = $country_array|sort('string')}
 
 <select name="study_country">
   <option value="-99" selected>Please select a country...</option>
   <option disabled>&nbsp;</option>
   {foreach $sorted_country_array as $sorted_country}
     <option>{$sorted_country}</option>
   {/foreach}
 </select>

This bit of code presents the list of attributes in the same order; i.e. the arraysortoperator extension is doing nothing. I noticed that the extension's description page states that it works with version 3.6 and 3.7, but I am using 3.8.

Any idea what is going wrong?

Good thinking. I turned on the debug output and found this line:

Warning: eZTemplate  	Sep 20 2006 17:19:51
Operator 'sort' is not registered

This is confusing though because the extension is registered in the admin screen. I tried both registering it manually by updating the necessary .ini files as well as using the Setup -> Extension form.

Am I missing a step?

Claudia, you're brilliant!

I never considered that the files were not unzipped correctly. I went into the extension directory and found this:

|-extension
|---arraysortoperator
|-----docs
|-------autoloads
|-------classes
|-------settings

The <b>docs</b> directory contained the other directories, which is clearly wrong. The correct directory structure should look like this:

|-extension
|---arraysortoperator
|-----docs
|-----autoloads
|-----classes
|-----settings

Now my countries are sorted correctly. Thank you!
