php - Data from associative array in Smarty -

i have associative array , made datadump of (see picture)

with smarty want pw_pro_code visible in select list

{foreach from=$clientprojects item=array}   {foreach from=$array item=pw_pro_code}     <option value="{$pw_pro_code}">{$pw_pro_code}</option>   {/foreach} {/foreach} 

but shows me both pw_pro_code , pw_wc_instanceid in list. doing wrong?

a single loop work -

{foreach from=$clientprojects item=array}     <option value="{$array.pw_pro_code}">{$array.pw_pro_code}</option> {/foreach}
