Retrieves values from [client_params] in the same manner that [action_param] retrieves values from [action_params]. An additional -explode option returns an array, for params that have multiple values. Safe to use inside [inline]. Requires [client_params] tag, available here.

Parameters

-count	boolean, optional	Adding -count will cause the tag to return the number of values returned matching the given name.
-explode	boolean, optional	Causes the tag to return an array of values.

Sample Usage

client_param('id');
client_param('checkme');
client_param('checkme', -count);
client_param('checkme', 2);
client_param('checkme', -explode);

-> 12345     // value of id
-> 1 2 3 4 5 // values of checkme
-> 5         // number of checkme items submitted
-> 2         // value of 2nd checkme item
-> (array: (1),(2),(3),(4),(5)) // array of checkme items
