Claudia Kosny	Thursday 14 September 2006 11:19:34 am Hello there As far as I know there is no inbuilt way to do this. The easy way out is to fetch all the country names in an array, sort this array and then loop through this array. Unfortunately there is no array sort function built into EZ so either take the contribution http://ez.no/community/contribs/template_plugins/arraysortoperator or just write your own wrapper for the php sort function.

Mindshare Interactive Campaigns	Friday 15 September 2006 12:12:52 pm 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> </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? http://www.mindshare.net
Claudia Kosny	Friday 15 September 2006 1:18:57 pm Hi there The sort operator of this extension works fine for me (EZ 3.8.3). Are you sure that the extension is loaded alright? If not you should see an message in the debug output that the operator sort is not defined. Another possible thhough unlikely problem might be interference from another extension which might already implement an sort operator wich behaves differently. Greetings from Luxembourg Claudia
Mindshare Interactive Campaigns	Wednesday 20 September 2006 7:23:45 am 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? http://www.mindshare.net
Claudia Kosny	Wednesday 20 September 2006 7:42:11 am Hi there Maybe the directry structure if the extension is not correct - this happens quite often to me if I unzip into a directory with the name of the extension and the zipfile provides already such a directory. So check your extensions folder and open the folder for the array sort extension. There you should see the folders autoloads and maybe settings (I already deleted the extension again so I am not sure). Claudia
Mindshare Interactive Campaigns	Wednesday 20 September 2006 10:36:26 am 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! http://www.mindshare.net
