Hello,
I want to change a column to a link?
Is it possible?

[victor]

Yes.
You can use a callback function.

[maha]

when i make it in the controller the condition implement on the whole records

[victor]

public function webpages()

{

$c = new grocery_CRUD();

$c->set_table('your_table');



// field 'action' is an extra virtual field

$c->columns('field1','field2','field4','[color=#ff0000]action[/color]');



$c->callback_column('action',array($this,'_callback_action'));



$output = $c->render();

$this->_view_output($output);

}



public function _callback_action($value, $row)

{

if($row->count >=1)

return '<a href="your_action/'.$row->id.'">'.$value.'</a>';

else return 'no product';

}

[maha]

this my code

 $crud = new grocery_CRUD();

   $crud->set_theme('flexigrid');

	$crud->set_table('project');

$crud->columns('name','slang','tlang','numwords','price','type','pvalid','state');

$crud->where("project.state = 2");	

$crud->add_action('rate', base_url().'images/good.png', '' ,'ui-icon-plus',array($this,'clientrate'));  

i want add_action display on a certain records that match the condithion
but the condition implements on all records(the records with state=2 only displayed)

[maha]

function clientrate($primary_key , $row)

			 {

				   // if ($row->state == 2){

					// $this->view_record(0,$primary_key);  

					  return  site_url('signup/addratting/'.$row->state);

				  

			 }

[victor]

sorry, but I don't understand what you want to do.


Do You want to put a rating for the row? or for state?

[victor]

$crud = new grocery_CRUD();
$crud->set_theme('flexigrid');
$crud->set_table('project');
$crud->columns('name','slang','tlang','numwords','price','type','pvalid','state',[b] [color=#ff0000]'rate'[/color][/b]);
$crud->callback_column('action',array($this,'_callback_action'));

public function _callback_action($value, $row)
{
if($row->state = 2 )
return '<a href="your_action/'.$row->id.'">'.$value.'</a>';
else return '';
}

[maha]

rate is not a field of table ,it's add_action button

[victor]

In my case "rate" is a button too. field "rate" isn't in a database.
try it:
$crud->columns('Yor field's .......', [color=#ff0000]'rate'[/color]);
columns 'rate' will be created automatically for the list.

[maha]

ok i'll try

[maha]

i tried it but doesn't work

[victor]

what an error do you have?

[victor]

$crud = new grocery_CRUD();

$crud->set_theme('flexigrid');

$crud->set_table('project');

$crud->columns('name','slang','tlang','numwords','price','type','pvalid','state', 'rate');

$crud->callback_column('rate',array($this,'_callback_action'));



public function _callback_action($value, $row)

{

   if($row->state = 2 )

   return '<a href="your_action/'.$row->id.'">'.$value.'</a>';

   else return '';

}

[maha]

i have no error , i have a column "rate" with no data.

[victor]

show your controller's code. and callback function

[maha]

my first controller code is

$crud->set_table('project');

$crud->columns('name','slang','tlang','numwords','price','type','pvalid','state');                

$crud->where("project.state = 2");      



 $crud->add_action('Show & Download', base_url().'images/show.png', '' ,'ui-icon-plus',array($this,'showaction'));

 $crud->add_action('rate', base_url().'images/good.png', '' ,'ui-icon-plus',array($this,'clientrate'));   

callback function is

function clientrate($primary_key , $row)

             {

                   if ($row->state == 2){

                    // $this->view_record(0,$primary_key);   

                      return  site_url('signup/addratting/'.$row->state);



             }

and this is print screen of my grid

i want the rate (yello stare) displaed only in the records with state= finished

[maha]

your code in controller is

$crud->callback_add_field('rate',array($this,'amount_field_add_callback'));

$crud->columns('name','slang','tlang','numwords','price','type','pvalid','state','rate');

									

callback function

public function _callback_action($value, $row)

	 {

	 if($row->state == 2 )

	   return '<a href="signup/addratting/'.$row->id.'">'.$value.'</a>';

   else return '';

	 }

and this is print screen of the result
