Action after delete

classic 2.6.7 “Action after delete” does not work using “rec_id”. Example I want to update a number in another table other than the one I am deleting when deleting a record and the idea is to make a subtraction through an INNER JOIN but it does not do it if I remove the “rec_id” makes the subtraction but to all the values ​​of the other table ... the point is that the "action after add" works perfect when adding a record. I hope it is understood if I will not pass project and base.

@alfre91‍ there is no bug there, just tested it with mine and it works perfectly. your MySQL query to perform that action might be wrong, the best way to be sure about that is to test your MySQL query with MySQL triggers. or the alternative is to create a sample so that I can set the correct Mysql statement for you. More about MySQL trigger

Thanks.

basis and the project

the idea is to guide me in how I have to put in "action after delete" or "action before delete"



THANK YOU

@alfre91‍ please add this
Code: [Select]
$db->rawQuery("UPDATE prueba SET data_list=data_list - 1 WHERE id='$modeldata['id_data']'");
to your "data" table Delete Page, Action After Delete and let me know if it works fine on yours.
why the record id($rec_id) does not work for you is because the record being deleted does not have its id reference on the prueba table, rather prueba table has its id referenced in the data table as  id_data.
thanks.

@alfre91‍ I noticed that the error from the previous query was because of no data in the $modeldata['id_data'] being used in the query. the new solution would be to add this 👇
Code: [Select]
$db->where('id',$rec_ids);
$prueba_id = $db->getValue('data', 'id_data');
to your Action Before Delete and add this 👇
Code: [Select]
$sql = "UPDATE prueba SET prueba.data_list = (prueba.data_list - 1) WHERE id = ".$prueba_id;
$db->rawQuery($sql);
to your Action After Delete. I hope this resolves your issue.

I return to the same topic, I would like to delete a record from the "prueba" table, delete the record from the "data" table taking into account that, "prueba.id" and the "data.id_data" are the same. Is it possible to do it from action after delete from the "prueba" table?.
what would I have to put?. thank you very much geniuses

@alfre91‍ the following code should do the trick.
Code: [Select]
$db->rawQueryOne("DELETE from tablename WHERE id IN ($rec_ids)");
 
Where tablename is the table you want to delete records from and id is the column that links the record to the current data that was deleted before executing the above delete query.

finally found newbee error,
this is what i do:
purchases>>Delete Page>> Action Before Delete:
Code: [Select]
$db->where('id',$rec_id);
$products_id = $db->getValue('purchases', 'product_id');

purchases>>Delete Page>>Action After Delete:
Code: [Select]
//$count_qty = $db->rawQuery("SELECT SUM(received_number) FROM purchases WHERE product_id=$products_id");

//execute SQL statement and return the result
//$params    = array($products_id);
//$count_qty = $db->rawQuery("SELECT SUM(received_number) FROM purchases WHERE product_id=$products_id", $params);

$sql = "UPDATE products SET products.received_inventory = (SELECT SUM(received_number) FROM purchases WHERE product_id=$products_id) WHERE id = $products_id ";
$db->rawQuery($sql);

 i originally want to use $count_qty instead a nested query, but it was fail to me.
please suggest with better sql query.

thank you

@heri.pmck‍ this is your query, written using the phprad query functions.

purchases>>Delete Page>>Action After Delete:
Code: [Select]
$db->where('product_id',$products_id);
$sum = $db->getValue('purchases', 'SUM(received_number)');

$sql = "UPDATE products SET products.received_inventory = ? WHERE id = ?";
$db->rawQuery($sql, array($sum, $products_id));
