Insert with php in mysql from CSV if not exists - php

Question

I got a problem and could't find a solution for me.
I want to insert with a php script in my mysql database from a csv file.
The database got a primary key, which is created automatically on every insert.
The csv file grows with time, but the existed date should not be inserted again! I could not check the primary key in this case, because it is generated on every insert.
This is my file so far:
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$import = "INSERT INTO xt_products(
products_owner,
products_quantity,
products_shippingtime,
products_model,
products_model_original,
products_price,
products_tax_class_id
) VALUES (
'$data[0]',
'$data[1]',
'$data[2]',
'$data[3]',
'wayne_$data[4]',
'$data[5]',
'$data[6]'
)";
mysql_query($import) or die (mysql_error());
}
I know about where exists or if exists bgin end, but I could not get it to work.
Edit: Forgot to mention it, it should check, whether the products_model is already in the database. That would be the $data[3] field there

Answer 1

You just have to add the duplicate statement
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$import = "INSERT INTO xt_products(
products_owner,
products_quantity,
products_shippingtime,
products_model,
products_model_original,
products_price,
products_tax_class_id
) VALUES (
'$data[0]',
'$data[1]',
'$data[2]',
'$data[3]',
'$data[4]',
'$data[5]',
'$data[6]'
)
ON DUPLICATE KEY UPDATE products_owner='$data[0]'
";
mysql_query($import) or die (mysql_error());
}

<?php
include ("config.php"); //Connect to Database
//Upload File
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) {
$import="INSERT into table(something,something,something,something,something,something,something) values('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]','$data[5]','$data[6]','$data[7]')";
mysql_query($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='import.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>";
}
?>
config.php
<?php
$db = mysql_connect('localhost', 'user', 'pass') or die("Could not connect.");
if(!$db)
die("no db");
if(!mysql_select_db("database",$db))
die("No database selected.");
?>
