[英]How can I insert to another table using the insert id?
I've got a problem like this , I cannot get the id of the parent table . 我遇到这样的问题,我无法获取父表的ID。
table_name : transaction_tbl
- transaction_id
-file_name
-file_path
-description
table_name : transaction_details
-details_id
-transaction_id
- details
here is my code to insert : 这是我要插入的代码:
$sql = "INSERT INTO transaction_tbl (`file_name`,`file_path`,`description`) VALUE('$file_name','$file_path','$description') " ;
$query = $conn->query($sql);
$transaction_id = mysqli_insert_id($conn);
if ($query === True ){
$sql = "INSERT INTO transaction_details (`transaction_id`,`details`) VALUES ($transaction_id,$details) ";
}else {
trigger_error('Wrong SQL: ' . $sql . 'Error: ' . $conn->error, E_USER_ERROR);
}
Now I can insert in my transaction_tbl but not in transaction_details. 现在,我可以在transaction_tbl中插入,但不能在transaction_details中插入。 what should I do?
我该怎么办? Can somebody help me?
有人可以帮我吗?
Add $query = $conn->query($sql);
添加
$query = $conn->query($sql);
inside if condition
as below if condition
如下
if ($query === True ){
$sql = "INSERT INTO transaction_details (`transaction_id`,`details`) VALUES ($transaction_id,$details) ";
$query = $conn->query($sql);
}
else {
trigger_error('Wrong SQL: ' . $sql . 'Error: ' . $conn->error, E_USER_ERROR);
}
