Cakephp save data and read MAX - cakephp

Question

I'm trying to save data in CakePHP in this way:
get max entry_id from table translations
(SELECT MAX(entry_id) as res FROM translations) + 1
save data into translations table
$translationData = array('entry_id' => $entry_id, 'language_id' => $key, 'text' => $item);
$translation = new Translation();
$translation->set($translationData);
$translation->save();
again get max entry_id
save next set of data
again get max entry_id
save next set of data
Please have a look at my code:
$this->request->data['Product']['name_tr_id'] = $this->Translation->saveTranslations($this->request->data['Product']['name']);
$this->request->data['Product']['description_tr_id'] = $this->Translation->saveTranslations($this->request->data['Product']['description']);
$this->request->data['Product']['seo_title_tr_id'] = $this->Translation->saveTranslations($this->request->data['Product']['seo_title']);
$this->request->data['Product']['seo_keywords_tr_id'] = $this->Translation->saveTranslations($this->request->data['Product']['seo_keywords']);
$this->request->data['Product']['seo_desc_tr_id'] = $this->Translation->saveTranslations($this->request->data['Product']['seo_desc']);
saveTranslations method:
public function saveTranslations($data) {
$entry_id = $this->getNextFreeId();
foreach($data as $key => $item) {
if($item != "") {
$this->create();
$temp['Translation']['entry_id'] = $entry_id;
$temp['Translation']['language_id'] = $key;
$temp['Translation']['text'] = $item;
$this->save($temp);
}
}
return $entry_id;
}
getNextFreeId method:
public function getNextFreeId() {
$result = $this->query("SELECT MAX(entry_id) as res FROM translations");
return $result[0][0]['res'] + 1;
}
I don't know why entry_id have all the time the same value.

Answer 1

After many hours of searching for solution I finally managed to solve the problem in very easy way - just add false parameter in query method:
$this->query("INSERT INTO translations(entry_id, language_id, text) VALUES($entry_id, $key, '$item')", false);
and
$result = $this->query("SELECT SQL_CACHE MAX(entry_id) as res FROM translations", false);
