To add a filter on a specific table column you can add an URL argument to your request that follows the following name convention:
wpda_search_column_<column_name>
Only GET requests are supported for publications!
Examples
YOUR-URL/?wpda_search_column_first_name=Sacha
<input name="wpda_search_column_first_name" type="text" value="Sacha" />
Adds condition
first_name = 'Sacha'
Wilcards are supported in URL parameters as well
YOUR-URL/?wpda_search_column_title=Last%
IN conditions
Use arrays to filter a column on multiple values (allows wildcard usage as well). For example:
YOUR-URL/?wpda_search_column_first_name[0]=Sacha&wpda_search_column_first_name[1]=Peter
Adds condition
first_name = 'Sacha' OR first_name = 'Peter'
OR conditions
Use parameter wpda_search_column_operator to compare using OR instead of AND. The plugin uses AND by default.
Example AND (default)
YOUR-URL/?wpda_search_column_first_name=Sacha&wpda_search_column_last_name=Schulz
Adds condition
first_name = 'Sacha' AND last_name = 'Peter'
Example OR
YOUR-URL/?wpda_search_column_first_name=Sacha&wpda_search_column_last_name=Schulz&wpda_search_column_operator=or
Adds condition
first_name = 'Sacha' OR last_name = 'Peter'
It is currently not possible to combine AND and OR conditions with URL parameters.
