Modify a row with CakePHP - php

Question

I'm using CakePHP to show a frontend GUI for a MySQL database table. I've used bake to auto generate the screens and I currently have a fully functioning app with View, Edit and Delete buttons per row. I want to add a button per row, called Accept, which should set IsAccepted = 1 on the SQL row.
I've managed to add an Accept button per row as follows:
echo $this->Html->link(__('Accept'), array('action' => 'accept', $product['Product']['ID']))
But the code in ProductController.php does not work:
public function accept($id = null){
...
$this->Product->IsAccepted = 1; // does not work, silently fails
}
What am I doing wrong? How do I properly edit a row using a per-row button?

Answer 1

public function accept($id = null){
$this->Product->save(array('id' => $id, 'is_accepted' => 1));
}

Answer 2

// assuming cake 2.1+
public function accept($id = null){
if($this->Product->exists($id)) {
$this->Product->saveField('is_accepted', 1);
// success..
}
// else throw not found exception...
}

Thanks to cornelb I found the answer! This is the final code I used to modify a row, with a per-row button.
Modifies the row when the per-row button is pressed (works just like a POST/AJAX button)
A flash message that says "Accepted!" shows if saving succeeds
Redirects back to the listing page (appears to never leave the listing)
This is the code that goes in ProductController.php (or whatever controller class you have):
public function accept($id = null) {
if ($this->Product->exists($id)) {
// save the row
// you absolutely need to fill the 'id' slot, even if its not your primary key!!
// this ensures that the row is EDITED, and not INSERTED!
if($this->Product->save(array('id' => $id, 'ID' => $id, 'IsApproved' => 1, 'ApprovedDate' => date('Y-m-d H:i:s', time())))){
// show a "flash" message
// (not Adobe Flash, just a message that shows on top of the list)
$this->Session->setFlash(__('The product has been accepted!'));
// this action does not have a view so no need to render
$this->autoRender = false;
// redirect to index view
return $this->redirect(array('action' => 'index'));
}
}
}

**Try this.....**
<?php
public function accept($id = null) {
$this->autoRender = false; // if action has not view.
if ($this->Product->exists($id)) {
$this->Product->id = $id;
if ($this->Product->save(array('is_accepted' => 1))) {
$this->Session->setFlash(__('The product has been accepted!'));
return $this->redirect(array('action' => 'index'));
}
}
}
?>

Just run updateAll query from accept function as shown below:
public function accept($id = null){
if(!empty($id)){
$this->Product->updateAll(
array('Product.is_accepted' => 1),
array('Product.id' => $id)
);
}
}
Hope this will help you...
