I tried all the things.. like only two checkboxes are selected and entering values into there corresponding textboxes still showing Notice: Undefined offset: i.e. echo $email[$j];

Complete code:

<?php

if(isset($_POST['submit']))
{
//echo print_r($_POST['contactid']);
    if(isset($_POST['equalkv']))
        $kv=$_POST['equalkv']; 
    if(isset($_POST['equallp']))
        $lp=$_POST['equallp'];

    $email=array();     
    $different_kvs=array();
    foreach($_POST['contactid'] as $i => $contenti)
            $email[$i]=$contenti;

    $elements = count($_POST['kv']);
    if($elements > 0) 
    {
        for($j = 0; $j <= $elements; $j++) 
        {
            echo $_POST['kv'][$j];
            echo $email[$j];
        }
    }
}
?>

The simple fix would be to use:

if (isset($email[$i]))
    echo $email[$i];

But you need to find the cause, not fix the effect.

Mine problem in brief: I tried all the things to do but not able to figure out.
I have some dynamic checkboxes and corresponding textboxes.
When a user ticks a checkbox and enters data into the corresponding textbox and submits, the value of the checkbox and textbox should be inserted into the database. I can insert the checkbox values perfectly, but the textbox values have issues. How I can do it ?
I am not able to print checkbox's textbox value. I already posted entire code.

Just before your if ($elements > 0) add the following code, and show what it outputs here:

print_r($_POST['kv']);
print_r($email);
0

Array ( [0] => 100 [1] => [2] => [3] => [4] => [5] => [6] => [7] => 100 [8] => [9] => [10] => [11] => [12] => [13] => [14] => [15] => [16] => ) Array ( [0] => haroonans123@gmail.com [1] => rahulkaw_79@yahoo.co.in ) 100haroonans123@gmail.comrahulkaw_79@yahoo.co.in

with 17 error messages : i.e.
Undefined offset: ---- on line 26 // line no. 26 is echo $email[$j];

Your loop loops 17 times, while the email array only holds 3 items. That's the problem.

Am I correct in saying the array's should only contain the information of the textboxes having checked checkboxes? And why does the first array contain only empty values?

Then, how I can solve this problem..? synchronising both checkbox and textbox loops..?

Do you have this online somewhere so I can view this? If not, post a screenshot explaining what's what.

I'm attaching the screenshot; and want to process only yellow boxes; as an example; it will vary..

The problem is that an unchecked checkbox does not get posted. You need a way to match the checkbox with the textbox, which can be done by using the index as a value (instead of the email), starting at 0. If you need the email you can create a hidden input array for them, similar to the textboxes.

Maybe try this (line 26):
echo isset($email[$j])?$email[$j]:"";
