хотите вставить загруженный файл csv в базу данных. он говорит «не выбрана база данных», что я пропустил?

<?php //connection to database include("sql/connect2DB.php"); if (isset($_POST['submit'])) { if (is_uploaded_file($_FILES['filename']['tmp_name'])) { echo "<h1>" . "File ". $_FILES['filename']['name'] ." uploaded successfully." . "</h1>"; echo "<h2>Displaying contents:</h2>"; readfile($_FILES['filename']['tmp_name']); } //Import uploaded file to Database $handle = fopen($_FILES['filename']['tmp_name'], "r"); while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { $import="INSERT into user(username,password, user_type) values('$data[0]','$data[1]', '$data[2]')"; mysql_query($import) or die(mysql_error()); } fclose($handle); print "Import done"; //view upload form } else { print "Upload new csv by browsing to file and clicking on Upload<br />\n"; print "<form enctype='multipart/form-data' action='test.php' method='post'>"; print "File name to import:<br />\n"; print "<input size='50' type='file' name='filename'><br />\n"; print "<input type='submit' name='submit' value='Upload'></form>"; } ?>
