assign value from attribute_view_gui from select attribute - ezpublish

Question

I have an attribute if type select. When i try to get value from this attribute content it gives the identification number instead of the value. I call like
$node.data_map.my_attribute_identifier.content
This is expected behaviour. https://doc.ez.no/eZ-Publish/Technical-manual/4.x/Reference/Datatypes/Selection
Raw output
The ".content" of an ezcontentobjectattribute object using this datatype returns an array of the identification numbers (as strings) of the selected options.
I want the value not the identification number. I can get that using attribute_view_gui like
attribute_view_gui attribute=$node.data_map.my_attribute_identifier
But i can't assign value to a variable this way. How can i assign value from a select attribute?

Answer 1

First of all i recommend you to always check default templates in your ezpublish to figure out how should template look...
Maybe this example will help:
<input
id="whatever_id_you_like"
type="text" size="50"
name="ContentObjectAttribute_ezstring_data_text_{$node.object.data_map.YOUR_ATTRIBUTE_SHORT_NAME.id}"
value="{$YOUR_VAR}"
/>
or u can use default view for attribute like this:
{attribute_view_gui attribute=$node.data_map.YOUR_ATTRIBUTE_SHORT_NAME}
also might be helpful - way to find correct path (sometimes you need add ".data_int" or ".data_text" on the end of the path to display data):
{$path|attribute(show,depth)} example:
{$node|attribute(show,2)}
or
{$YOUR_FANCY_VAR.content|attribute(show,2)}

You may want to take a look at the view template of ezselection:
ezselection.tpl
This is the code that eZ Publish uses to view the data type.
content of ezselection.tpl:
{let selected_id_array=$attribute.content}
{section var=Options loop=$attribute.class_content.options}
{section-exclude match=$selected_id_array|contains( $Options.item.id )|not}
{$Options.item.name|wash( xhtml )}{delimiter}<br/>{/delimiter}{/section}
{/let}
