Insert the data of multiple tabs created by user in MYSQL - php

Question

I am trying to insert the data of text area of tabs in MYSQL using PHP. I am able to insert the data of only predefined tab but I am not able to insert the data of newly created tabs when user clicks on ADD TAB button and create his own tab.
Any ideas how it can be done?
here is my HTML output: http://jsfiddle.net/HMv9S/1/
I have tried this MySQL code for inserting the data and successfully can insert the data of predefined tab:
<?php
if ($_POST['submit'])
{
$con=mysqli_connect("localhost","root","","my_db");
$texts=array($_POST['txt']);
foreach($texts as $value)
{
$allTextArea = implode(",", $value);
$text = mysql_real_escape_string($allTextArea);
$query= "INSERT INTO Sections(data) VALUES('$text')";
mysqli_query($con,$query);
}
}
?>

Answer 1

You should name the textarea as an array like txt[] instead of txt. Now on form submit you will get all the textarea values.
if ($_POST['submit']){
$allTextArea = $_POST['txt'];
print_r($allTextArea);
}

Answer 2

Input elements attribute name must be unique (semantically also id). Then iterate through possible keys received in $_POST.
In single form you are creating multiple input elements (in your case <textarea>) with same name attribute. in $_POST, values are sent in format 'key' => value with input element attribute name as key. All your textareas has 'txt' as name.
