Hello ! I want to extract 20 characters from my article.I didn't find the syntax for using extract_left with {attribute_view_gui attribute=$node.object.data_map.intro}
Someone of you know how to use ???? Thankskavi

Did you try? {attribute_view_gui attribute=$node.object.data_map.intro|extract_left(20)}

Hi,
This won't work since extract_left should be used on a string.
You need to apply this directly on the output of the content of your datatype.
{$node.data_map.intro.content|extract_left( 20 )}
This means this is incompatible with the attribute_view_gui operator.

Hi Nabil ! thanks for your quick answer. I've just tried your suggestion. But it doesn't work !!!My code is in the override/templates/listitem/article.tpl
<li class="extraitNews"> <h1> <a href={$node.url_alias|ezurl} title="Lien vers : {$node.object.data_map.title.content|wash}">{$node.object.data_map.title.content|wash}</a> </h1> <p>{attribute_view_gui attribute=$node.object.data_map.intro} </p> </li>
If extract_left is incompatible with attribute_view_gui, do you think that i've to modify another template..?!kavi
