insert multiple values using a query as array - php

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.

Answer 2

Let's give it a wild guess and assume that this is what you want:
//query to get all user concerning the department
$query = mysql_query("
SELECT userid
FROM dept_user
WHERE dept_id=$dept
");
if(mysql_num_rows($query)){
$insertSQL = "
INSERT INTO course_detail
(userid, course_id, date_assign, expected_end_date, owner)
VALUES
";
$rowsSQL = Array();
while($row = mysql_fetch_row($query)){
$rowsSQL[] = "('{$row['userid']}','$name','$sdate', '$edate', '$m_name')";
}
mysql_query($insertSQL.implode(',', $rowsSQL));
}
Also you should start reading the manual.

Answer 3

Read the doc, you can separate each set of data with a comma.

Answer 4

$values = array();
$values[] = array(
'id' => 1,
'v1' => 'a',
'v2' => 'b'
);
$values[] = array(
'id' => 2,
'v1' => 'c',
'v2' => 'd'
);
$sql = "INSERT INTO course_details (id,v1,v2) VALUES ";
foreach ($values as $value) {
$sql .= '('.$value['id'].','.$value['v1'].','.$value['v2'].'),';
}
$sql = substr ($sql,0,-1) // that will remove the last comma
mysql_query($sql);

Answer 5

Below is the function and here is how to use it
Update Query
$data_array=array(
"bannername" => addslashes($_POST["bannername"]),
"url" => $_POST["url"],
"openin" => $_POST["openin"]
);
$param=" bannerid = '$bannerid'";
$sql=db_makequery("banner",$data_array,"update",$param);
Insert Query
$data_array=array(
"bannername" => addslashes($_POST["bannername"]),
"url" => $_POST["url"],
"openin" => $_POST["openin"]
);
$sql=db_makequery("banner",$data_array);
Function
function db_makequery($table, $data, $action = 'insert', $parameters = '')
{
reset($data);
if ($action == 'insert')
{
$query = 'insert into ' . $table . ' (';
while (list($columns, ) = each($data)) {
$query .= $columns . ', ';
}
$query = substr($query, 0, -2) . ') values (';
reset($data);
while (list(, $value) = each($data))
{
switch ((string)$value)
{
case 'now()':
$query .= 'now(), ';
break;
case 'null':
$query .= 'null, ';
break;
default:
//$query .= '\'' . tep_db_input($value) . '\', ';
$query .= '\'' . $value . '\', ';
break;
}
}
$query = substr($query, 0, -2) . ')';
}
elseif ($action == 'update')
{
$query = 'update ' . $table . ' set ';
while (list($columns, $value) = each($data))
{
switch ((string)$value) {
case 'now()':
$query .= $columns . ' = now(), ';
break;
case 'null':
$query .= $columns .= ' = null, ';
break;
default:
//$query .= $columns . ' = \'' . tep_db_input($value) . '\', ';
$query .= $columns . ' = \'' . $value . '\', ';
break;
}
}
$query = substr($query, 0, -2) . ' where ' . $parameters;
}
return $query;
}
