Update only the specific field in cakephp -


i have small problem. have table item_pictures has 6 fields img1 | img2 | img3 | ima4 | img5| store 5 images. means 1 row of batabases has 5 fields store path of images. wanna create kind of button next each image when user click it, update field of image making empty, thats want. want update or change 1 speciffic field. possible , if how??

thats code have comme far:

$this->form->postlink($this->html->tag('i', '',                  array('class' => 'glyphicon glyphicon-remove')),                 array('controller' => 'item_pictures','action' => 'delete_current_img', $item['item']['id'] .'-'. 'img'.$i .'-'. $pictures['img'.$i]) ,                 array('escape' => false), __('are sure want delete image?'))

so want in controller grab variable , update row id => $item['item']['id'] , on column img.$i value $pictures['img'.$i], , make empty...

i think pretty close, cycle $i = 1 $i = 5 with

$item_picture_id = $item['item']['itempicture']['id'] //or something, im not sure how have done relations  echo $this->form->postlink($this->html->tag('i', '',     array('class' => 'glyphicon glyphicon-remove')),     array('controller' => 'item_pictures','action' => 'delete_current_img', $item_picture_id, 'img'.$i) ,     array('escape' => false), __('are sure want delete image?'));

so example image 5 ($i = 5) should resolve url: item_pictures/delete_current_img/id/img5/

then controller have (very simple example):

public function delete_current_img($id,$field){     $this->itempicture->id = $id;     $this->itempicture->savefield($field,'');     //then go come     $this->redirect(array('controller' => 'foo', 'action' => 'where_ever_the_delete_came_from')); }

hope helps!
