HTML：

<form action="importData.php" method="post" enctype="multipart/form-data" id="importFrm1"> <input type="file" name="file" style="margin-top: 30px;px;" /><br> <input type="submit" class="btn btn-primary" id="importSubmit" name="importSubmit" value="IMPORT" style="margin-top: 0px;"> </form>

  <?php session_start(); if(!isset($_SESSION['username'])) { header("Location:sessionerror.php"); exit; } include "connection2.php"; //load the database configuration file if(isset($_POST['importSubmit'])){ // Validate whether uploaded file is a csv file $csvMimes = array('application/vnd.ms-excel','text/csv'); if(!empty($_FILES['file']['name']) && in_array($_FILES['file']['type'],$csvMimes)){ if(is_uploaded_file($_FILES['file']['tmp_name'])){ //open uploaded csv file with read only mode $csvFile = fopen($_FILES['file']['tmp_name'], 'r'); //skip first line fgetcsv($csvFile); // Parse data from csv file line by line while (($line = fgetcsv($csvFile,1000, "\t")) !== FALSE){ $ID=$line[0]; $projectName=$line[1]; $projectLocation=$line[2]; $builderName=$line[3]; $builderGrade=$line[4]; $wheatherOCReceived=$line[5]; $startingPriceRs=$line[6]; $size_SBA=$line[7]; $configuration=$line[8]; $discount=$line[9]; $segment=$line[10]; $amenities=$line[11]; $filenme=$line[12]; $DateModified=$line[13]; //check whether member already exists in database with same email $prevQuery = "SELECT id FROM info WHERE id = '".$line[0]."'"; $prevResult = $conn->query($prevQuery); if($prevResult->num_rows > 0){ //update member data $conn->query("UPDATE `featured_projects`.`info` SET `projectName`='$projectName',`projectLocation`='$projectLocation',`builderName`='$builderName',`builderGrade`='$builderGrade',`wheatherOCReceived`='$wheatherOCReceived',`startingPriceRs`='$startingPriceRs',`size_SBA`='$size_SBA',`configuration`='$configuration',`discount`='$discount',`segment`='$segment',`amenities`='$amenities',`featuredImage`='$target_file',`date`='$DateModified' WHERE `id` = '".$ID."'") or die("Unable to update: " . $conn->connect_error); }else{ //insert member data into database $conn->query("INSERT INTO `featured_projects`.`info` (`id`, `projectName`, `projectLocation`, `builderName`, `builderGrade`, `wheatherOCReceived`, `startingPriceRs`, `size_SBA`, `configuration`, `discount`, `segment`, `amenities`, `featuredImage`, `date`) VALUES ('$ID', '$projectName', '$projectLocation', '$builderName', '$builderGrade', '$wheatherOCReceived', '$startingPriceRs', '$size_SBA', '$configuration', '$discount', '$segment', '$amenities', '$filenme', '$DateModified')" or die("Unable to Insert: " . $conn->connect_error); } } //close opened csv file fclose($csvFile); $qstring = '?status=succ'; }else{ $qstring = '?status=err'; } }else{ $qstring = '?status=invalid_file'; } } //redirect to the listing page header("Location: admin-ready-home-in-bangalore2.php".$qstring);?>
