Answer 1

You need to learn how mysql interacts with the DB. You will likely need to use VARCHAR datatype depending on how big you text area is. So if the field from the from is up to 250 characters then the text area column's datatype would be VARCHAR(250).
You would do a POST request to a file with something like this:
$post = $_POST;
//set other fields here, I recommend sanitizing your inputs.
...
$textarea = $_POST['text_area'];
$servername = "HOST";
$username = "username";
$password = "password";
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO MyGuests (...other columns you have, textarea)
VALUES (..., $textarea)";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}

It would have been easier if I had a look at your form data. I'll assume my own form data to try and answer your question.form.php
<form action="processing.php" method="POST">
<textarea required name="records" class="form-control" rows="8" cols="4" placeholder="Enter records separated by new line"></textarea>
<button type="submit" name="addRecords" class="btn btn-warning">Add Records</button>
</form>
Then processing.php
if (isset($_POST['addRecords'])) {
$record = $_POST['records'];
//explode records based on new line \n
$records = explode("\n", $record);
foreach ($records as $new) {
$data = $new;
//Here you'll write your sql code to insert records in the database
}
}
