Question

i’m trying to insert multiple data using a query, i’ve tried the implode function, the while loop, for loop, but still can’t be done..
can u help plz

well i’ve a combobox box for selecting course name, created a function to get its ID and assign a variable. supose i’m a manager of a department and need to assign all staff below me a course, i select the course, input the date assigned and expected ending date. i’ve created another field in database to enter the training owner. Since i’m the 1 assigning the course, my name will appear as owner field.

$m_name = $_SESSION['SESS_FIRST_NAME'];
//combobox to get the department ID using variable $dept
//query to get all user concerning the department
$query  = mysql_query("select userid from dept_user where dept_id=$dept LIMIT 0, 30 ");
$row= mysql_query($query);

//from here i'm not being able to execute
 $qry = mysql_query("INSERT INTO course_detail(userid, course_id, date_assign, expected_end_date, owner) VALUES('$query','$name','$sdate', '$edate', '$m_name')" ) ;

Answer 1

$qry = mysql_query("INSERT INTO course_detail(userid, course_id, date_assign, expected_end_date, owner) VALUES('$query','$name','$sdate', '$edate', '$m_name')" ) ;

So, you’re basically trying to insert $query in the userid column. In your code, $query is the result of a mysql select statement, thus a multi-array of user ids. Think of it like a simple SQL query, you can’t execute that. Even more, you’re doing mysql_query on a mysql_query result, which is plain wrong. Where does the $dept variable come from? What about the others? If you’re sure they’re valid here’s what you need:

// Get the user ids you need to insert in the db
$query = "select userid from dept_user where dept_id=$dept LIMIT 0, 30 "; // this will select the first 30 users in a dept
$buffer = mysql_query($query); // this is a variable that will hold all the results returned by the query above

// While we still have results in the $buffer array, fetch those in the $data array
while ($data = mysql_fetch_assoc($buffer)) {
    $insert_query = "INSERT INTO course_detail(userid, course_id, date_assign, expected_end_date, owner) VALUES('".$data['userid']."','$name','$sdate', '$edate', '$m_name')"; // add the userid from the first query and the other data (don't know where you got those
    $insert_buffer = mysql_query($insert_query); // execute the statement above, watch out so you don't overwrite the initial $buffer variable
}
// At this point you should have all the data in database

Also, I’m not sure you got the insert statement right

• userid > $data[‘userid’] (ok)
• course_id > $name (?!)
• date_assign > $sdate (you sure?)
• expected_end_date > $edate (ok)
• owner > $m_name (ok?)

Make sure you have a good naming convention or else you get lost very easy.

Good luck, a lot of mistakes on just 5 lines of code.
