I have a reviewfile.php whereby it reads in a file and process it by the following criteria by inserting the data into database:
- Duplicated results
- Results without comments
- Results of data with source or destination that is "Any".
I have SQL statement for each condition.
After printing results of the SQL statements, i would like delete all data of the database table so that if i upload a new file, insertion of data is fresh.
P.S: I do not want to drop table.
May i seek some help please:)
Below is my codes
if(isset($_POST['reviewFile'])){
if (isset($_POST['fileSelected'])){
$SelFile = $_POST['fileSelected'];
$query=$con->prepare("SELECT * from file where file_name = '$SelFile'");
$query->bind_result($file_id, $uid, $file_name, $file_size);
$query->execute();
$query->fetch();
$query->close();
$path = 'C:/xampp/htdocs/fwrule/fw/fileuploads/';
$file_to_get = $path.$SelFile;
$_SESSION['tmpfname'] = $file_to_get;
$_SESSION['excelReader'] = PHPExcel_IOFactory::createReaderForFile($_SESSION['tmpfname']);
$_SESSION['excelObj'] = $_SESSION['excelReader']->load($_SESSION['tmpfname']);
$_SESSION['worksheet'] = $_SESSION['excelObj']->getSheet(0);
$_SESSION['lastRow'] = $_SESSION['worksheet']->getHighestRow();
$_SESSION['highestColumn'] = $_SESSION['worksheet']->getHighestColumn();
//loop through each row of the worksheet in turn
for ($_SESSION['row'] = 3; $_SESSION['row'] <= $_SESSION['lastRow']; ++$_SESSION['row']) {
//read a row of data into an array
$rowData = $_SESSION['worksheet']->rangeToArray('A'.$_SESSION['row']. ':'.$_SESSION['highestColumn'] . $_SESSION['lastRow'], NULL, TRUE, FALSE);
//insert rows into database
$InsertData = $con->prepare("INSERT INTO file_data(id, file_id, no, name, source, destination, hit_counts, service, action, track, install_on, time, comment)

$InsertData->execute();
$InsertData->store_result();

The codes are working fine except for the part where I want to delete data from database table.
This is the part that is not working:
if ($DuplicatedRows == true && $checkforAny == true && $checkforComments == true)
{
$delAllData = $con->prepare("DELETE * from file_data");
$delAllData->bind_result();
if ($delAllData->execute())
{
$delAllData->fetch();
echo "hi";
}
$delAllData->close();
}
