page_path_unique
A validator to check whether a resource’s page path is unique:
<input type="text" id="page_path" name="page_path" value="">
{% validate id="page_path" type={page_path_unique} %}
Optionally, pass an id
parameter to exclude that particular id when testing
for uniqueness. This is useful when you want to exclude the page paths of the resource
currently being edited:
<input type="text" id="page_path" name="page_path" value="">
{% validate id="page_path" type={page_path_unique id=id} %}
You can also pass a failure_message
:
<input type="text" id="page_path" name="page_path" value="">
{% validate id="page_path" type={page_path_unique id=id failure_message=_"Eek! Already used!"} %}
