"insert" query do not work unless I call d() debug function

[maria zagula]

Hi experts!

 

I have very simple code:

$aaa = Db::getInstance()->insert('feature_product', array(
'id_feature' => $id_feature,
'id_product' => $id_product,
'id_feature_value' => $id_feature_value,
));

an this code does not works hovewer if I add d($aaa) after the code 

 

$aaa = Db::getInstance()->insert('feature_product', array(
'id_feature' => $id_feature,
'id_product' => $id_product,
'id_feature_value' => $id_feature_value,
));*/
d($aaa);

I get message '1' and database updates correctly ! 

1. I have tried with Db::getInstance()->execute($sql); and it gives me exactly the same behaviour. 

2. In other part of the code I have almost identical function and it works withour any problems etc.

 

Thanks in advance for help!

Try getting rid of that last comma in the array, after $id_feature_value

Thanks for your reply !

Unfortunatelly this is not the case (or I do not understand something).

 

This is the whole code of actionProductSave hook 
 

public function hookActionProductSave($params) {
		$id_feature = 10;
		$id_feature_value = 43;
		if (isset($params['id_product'])) 
		{
			$id_product=$params['id_product'];
			if($params['product']->date_add<$params['product']->available_date)
			{
				$sql = 'SELECT * FROM '._DB_PREFIX_.'feature_product WHERE  id_product='.$id_product.' AND id_feature='.$id_feature;
				$results = Db::getInstance()->ExecuteS($sql);
				if (!$results)
				{	
				Db::getInstance(_PS_USE_SQL_SLAVE_)->insert('feature_product', array(
				'id_feature' => $id_feature,
				'id_product' => $id_product,
				'id_feature_value' => $id_feature_value
				));	
				//d('anything');
				}			
			}			
		}
		return 'anything';
	}

If I have "d('anything');" commentened nothing works. If i have d('anything') not commented my database updates properly :/

 

Anybody have any idea why simple d() influance the code so much ?

 

Best regards  and thanks in advance !

There is a chance something else runs after that, if you don't kill the script. Depending on where you run the hook. In 1.6+ it's better to use hookActionProductUpdate anyway.
Also turn on error reporting, a simple insert should die on duplicate keys
