Insert new IDs as Foreign Keys in 2nd tab right after they got written Problem with writing multiple foreign keys. erroronexit msg:4028519 3:18 am on Nov 20, 2009 (gmt 0) I am new to PHP, not sure this belongs to PHP or MySQL. Here is my scenario:
I have multiple data from a form search that I want to write to 2 tables. So far that's no problem.
But the incremental IDs (plural!) that are created in TABLE1.ID should be inserted as foreign keys in TABLE2.ID_T1
My first thought was that mysql_insert_id()or last_insert_id() would come in handy - but they just can handle one ID, but I insert several.
Does anybody has clue how to work this out?

not sure what you want to do. could you not append each last_insert_id to an array and then do the second batch of inserts? erroronexit msg:4028578 6:09 am on Nov 20, 2009 (gmt 0)
I did a workaround now. I created a new field in TABLE1 and inserted there the source ID. Then I take the incremented TABLE1.ID and put it into TABLE2 as foreign ID. Seems to work. $sql = "INSERT INTO table1 (field1)VALUES ('" .implode("'), ('", $_POST['checkbox']) . "')";
mysql_query($sql) or exit(mysql_error());
$sql = "INSERT INTO table2 (id_t1)
SELECT table1.id FROM table1 WHERE field1 IN ('" .implode("', '", $_POST['checkbox']) . "') ";
