Then when I upload this csv file doesn't work.
This is my code..
<?php
session_start();
include ("config.php");
$extension = end(explode(".",basename($_FILES['file']['name'])));
if (isset($_FILES['file']) && $_FILES['file']['size'] < 10485760 && $extension== 'csv')
{
$file = $_FILES['file']['tmp_name'];
$handle = fopen($file, "r");
try
{
$connection = new pdo("mysql:host=$hostname;dbname=upload",$username,$password);
if
$upload = $connection->prepare("INSERT INTO tbl_upload(firstname,lastname,middlename,gender)
VALUES (?,?,?,?)");
if($handle !== false)
{
fgets($handle);
while (($data = fgetcsv($handle, 10000, ',') !== false))
{
$upload->execute($data);
}
fclose($handle);
$connection = null;
echo "<p class='bg-success'>Upload Success</p>";
header ("location: index.php");
}
}
catch(pdoExecption $e)
{
die($e->getmessage());
}
}
else
{
header("location:config.php");
}
?>
thanks for the help..

Answer 1

Your method is not viable.
To import CSV you can either use the mysqlimport utility or you have to split the csv records in separate fields to match your INSERT statement. You cannot just feed CSV to the insert statement and hope that it sorts out things for itself.

Answer 2

I can give you a little CsvImport class I wrote some time ago make importing CSV a little bit easier
<?php
final class CsvImport {
private $file = "";
private $fields = array(); //array("field1", "field2", "field3"); ...
private $data = array(); //array([1] => array("value", "value", "value") ...
private $delimiter = "";
private $fieldCount = 0;
private $rowCount = 0;
private $internalCounter = 0;
private $loaded = false;
public function __construct($_file, $_delimiter = "") {
$this->file = $_file;
if(is_file($this->file) == true) {
if(($handle = fopen($this->file, "r")) !== false) {
//If the delimiter is not set try to suggest it
if(strlen($_delimiter) == 0) {
$this->delimiter = $this->suggestDelimiter();
} else {
$this->delimiter = $_delimiter;
}
if(strlen($this->delimiter) > 0) {
$row = 0;
while(($data = fgetcsv($handle, 0, $this->delimiter)) !== false) {
if($row == 0) {
$this->fieldCount = count($data);
}
if($this->fieldCount > 0) {
for($c = 0; $c < $this->fieldCount; $c++) {
if($row == 0) {
$this->fieldCount = count($data);
$this->fields[] = $data[$c];
} else {
$this->data[$row][$this->fields[$c]] = utf8_encode($data[$c]);
}
}
}
$row++;
}
$this->rowCount = $row;
if($this->fieldCount > 0) {
$this->loaded = true;
}
}
}
}
}
public function getNextRow() {
$retVal = false;
if($this->loaded == true) {
if($this->internalCounter < $this->rowCount) {
$this->internalCounter++;
$retVal = true;
} else {
$this->internalCounter = 0;
}
}
return $retVal;
}
public function readField($field) {
$retVal = false;
if($this->isLoaded() == true) {
if(isset($this->data[$this->internalCounter][$field]) == true) {
$retVal = $this->data[$this->internalCounter][$field];
}
}
return $retVal;
}
public function resetInternalCounter() {
$this->internalCounter = 0;
}
public function getFieldCount() {
return $this->fieldCount;
}
public function getRowCount() {
return $this->rowCount;
}
public function getFieldList() {
return $this->fields;
}
public function getDelimiter() {
return $this->delimiter;
}
public function isLoaded() {
return $this->loaded;
}
private function suggestDelimiter() {
$retVal = "";
$file = fopen($this->file, 'r');
$content = fgets($file);
fclose($file);
if(strlen($content) > 0) {
$list = array(
"," => substr_count($content, ","),
"." => substr_count($content, "."),
"&" => substr_count($content, "&"),
"%" => substr_count($content, "%"),
"-" => substr_count($content, "-"),
";" => substr_count($content, ";"),
"'" => substr_count($content, "'"),
"\"" => substr_count($content, "\""),
);
$maxCount = 0;
foreach($list as $key => $value) {
if($value > 0) {
if($value > $maxCount) {
$retVal = $key;
$maxCount = $value;
}
}
}
}
return $retVal;
}
private function __clone() { }
}
?>
The usage is as simple as this:
$file = "/path/to/file.csv";
$import = new CsvImport($file);
if($import->isLoaded() == true) {
while($import->getNextRow()) {
foreach($import->getFieldList() as $fieldName) {
$value = $import->readField($fieldName);
echo $fieldName . " => " . $value . "<br />";
}
}
}
I am sure you can build your queries with all field names in the foreach loop and fire each query in the while loop.
