[HELP] Adding data to MYSQL with PHP

[Binsu]

To insert data into the database using the provided code block, you need to make some adjustments to avoid the "undefined index" error and allow only the fields with data to be inserted while leaving the rest empty. Here's the rewritten content in English for better readability:

```php
if ($_POST) {
$field1 = isset($_POST["1"]) ? $_POST["1"] : "";
$tarihsaat = date("Y-m-d h:i:s");
$field2 = isset($_POST["2"]) ? $_POST["2"] : "";
$field3 = isset($_POST["3"]) ? $_POST["3"] : "";
$field4 = isset($_POST["4"]) ? $_POST["4"] : "";
$field5 = isset($_POST["5"]) ? $_POST["5"] : "";
$field6 = isset($_POST["6"]) ? $_POST["6"] : "";
$field7 = isset($_POST["7"]) ? $_POST["7"] : "";
$field8 = isset($_POST["8"]) ? $_POST["8"] : "";
$field9 = isset($_POST["9"]) ? $_POST["9"] : "";
$field0 = isset($_POST["0"]) ? $_POST["0"] : "";
$field10 = isset($_POST["10"]) ? $_POST["10"] : "";

if (!empty($field1)) {
// Insert Data
$insert = mysql_query("insert into islem (1, tarih, 2, 3, 4, 5, 6, 7, 8, 9, 0, 10) values ('$field1', '$tarihsaat', '$field2', '$field3', '$field4', '$field5', '$field6', '$field7', '$field8', '$field9', '$field0', '$field10')");

if ($insert) {
echo "Transaction completed successfully";
} else {
echo "An error occurred during the transaction";
}
}
}
```

Make sure to review and adjust the code accordingly to suit your specific requirements and avoid the "undefined index" error when inserting data into the database.
