Re: How to remove items from $this->data

Create a function in your controller:

private function filter_my_data()

{

           unset($this->data['ChartsKpi'][x]);

}

// And use it in your add/edit functions

function add() {

   if(!empty($this->data)) {

       $this->filter_my_data();

       ...........

       ........... // Save Data

   }

}

Hi

I'm using CakePHP 1.2.3.8166 with PHP 5.2.9 on Apache 2.10

I'm hoping someone will give me a hand with what is essentially a PHP
question as oposed to a question about CakePHP.

I'm returning this data array from my add.ctp view:

Array
(
   [Chart] => Array
       (
           [title] => Test Chart
           [chart_type_id] => 1
           [width] => 128
           [height] => 128
       )

   [ChartsKpi] => Array
       (
           [1] => Array
               (
                   [kpi_id] => 1
                   [kpi_colour_id] => 2
                   [width] => 5
               )
           [2] => Array
               (
                   [kpi_id] => 2
                   [kpi_colour_id] => 3
                   [width] => 5
               )
           [3] => Array
               (
                   [kpi_id] => 0
                   [kpi_colour_id] =>
                   [width] =>
               )
           [4] => Array
               (
                   [kpi_id] => 0
                   [kpi_colour_id] =>
                   [width] =>
               )
           [5] => Array
               (
                   [kpi_id] => 0
                   [kpi_colour_id] =>
                   [width] =>
               )
           [6] => Array
               (
                   [kpi_id] => 0
                   [kpi_colour_id] =>
                   [width] =>
               )
           [16] => Array
               (
                   [kpi_id] => 0
                   [kpi_colour_id] =>
                   [width] =>
               )
           [17] => Array
               (
                   [kpi_id] => 0
                   [kpi_colour_id] =>
                   [width] =>
               )
.......
       )
)

You see all the sub arrays of [ChartsKpi] that have a kpi_id == 0? I
dont want to save those so I've a beforeSave callback in my ChartsKpi
model and I was trying to unset($this->data['ChartsKpi'][x]); but this
isn't working.

Is there an accepted way for taking data out of $this->data before
doing a save?

Thanks

David
