Bug description: mysql_query() duplicate entries
Description:
------------
I use mysql_query() to execute an insert statement into MySql db (ver
4.0.21). Sometimes the query executes correctly inserting a unique record
into the table. Other times it inserts two duplicate records.
I've tested this several times, and get this random result...however more
duplicate entries than single entry during my tests.
Reproduce code:
---------------
$host = 'localhost';
$user = 'user';
$pass = 'pass';
$db = 'db';
//$selected_prj = $_GET['prjID'];
$formsubmit = 0;
$formsubmit = $_POST['formsubmit'];
$conn = mysql_connect($host, $user, $pass) or die ('I cannot connect to
the database because: ' . mysql_error());
mysql_select_db ($db, $conn) or die("Couldn't access database $db on MySQL
server $host: ".mysql_error());
if ($formsubmit == '1'){
$queryInsert = "Insert into prjs (prjOwnerID, prjAssignedTo, prjTypeID,
prjName, prjDescription, prjComments, prjStatusID, startDate, endDate,
CreateDate, LastUpdate) Values (" . $_POST['ClientID'] . ", " .
$_POST['AssignedToID'] . ", " . $_POST['prjTypeID'] . ", '" .
$_POST['prjName'] . "', '" . $_POST['prjDescription'] . "', '" .
$_POST['prjComments'] . "', " . $_POST['prjStatusID'] . ",'" .
$prj_StartDate . "', '" . $prj_EndDate . "', now(), now())";
if(!($Result = mysql_query($queryInsert))){
// get error and error number
$errno = mysql_errno($conn);
$error = mysql_errno($conn);
print("Error $errno: $error<br>\n");
}
else{
print("<script language=\"javascript\"> ");
print("window.opener.location='./myaccount.php'; ");
print("self.close();");
print("</script>");
}
}
Expected result:
----------------
Record is inserted, opening window gets refreshed and current window is
closed.
Actual result:
--------------
two Records are inserted, opening window gets refreshed and current window
is closed.
