食品杂货add_action如何使用pk？

Question

see this article of the website of grocery-crud:

http://www.grocerycrud.com/documentation/options_functions/add_action

for testing I used this line:

$crud->add_action('Smileys', 'http://www.grocerycrud.com/assets/uploads/general/smiley.png', 'test');

so when I point my mouse on the smiley I see the adress ..../index.php/test/1 (primary key)

I have a model with this function:

that calls

$this->db->where('cust_id', '1');

how do I manage to pass that primary key as a variable ?

It's hard for me to explain, I hope you guys know what I mean.

so I want the pk from the add_function stored so I can use that variable in a model

Regards,

Ralph

Answer 1

You have to use callback function for this.. for example

$crud->add_action('Smileys', '','','' array($this,'_just_a_test'));

'just_a_test' is callback function.. so i create a function in the same controller like this..

function _just_a_test($primary_key , $row)
{
    return $row->id;
}

you can select any field from your $crud->columns params to replace my $row->id eg $row->country

OR

you can edit existing column like this..

$crud->callback_column('smiley', array($this,'_just_a_test2'));

and the callback function

function _just_a_test2($primary_key , $row)
{
    return '<a href="controller/method/'.$row->id.'"><img src="http://www.grocerycrud.com/assets/uploads/general/smiley.png"></a>';
}

dont forget to add 'smiley' in $crud->columns

$crud->columns('city','country','phone','smiley');

hope u find this useful.
