callback_add_field

void callback_add_field( string $field , mixed $callback )

This callback escapes the default auto field output of the field name at the add form. There are no parameters to this callback. You must return to the callback function a string.

Example:

function example_callback_add_field(){
    $crud = new grocery_CRUD();
 
    $crud->set_table('offices');
    $crud->set_subject('Office');
    $crud->required_fields('city');
    $crud->columns('city','country','phone','addressLine1','postalCode');
 
    $crud->callback_add_field('phone',array($this,'add_field_callback_1'));
    $crud->callback_add_field('state',array($this,'add_field_callback_2'));
 
    $output = $crud->render();
 
    $this->_example_output($output);
}
 
function add_field_callback_1()
{
    return '+30 <input type="text" maxlength="50" value="" name="phone" style="width:462px">';
}
 
function add_field_callback_2()
{
    return '<input type="text" maxlength="50" value="" name="state" style="width:400px"> ( for U.S. only )';
}
