How to retrieve textbox data in php

Question

I want to retrieve the data from a textbox which I created. Please take look at my code and help me.

<?php
if(isset($_GET['ok']))
{
$a=1;
$n=$_GET['n'];
for($i=0;$i<$n;$i++){
    echo '<form action="exa.php" method="get">';
echo '<input type="text" name="kal'.$a.'"/> <br/>'; 
echo '</form>';
$a++;} $a=1;
for($i=0;$i<$n;$i++)
{
    $txtnm="kal".$a;
    $kal=$_GET['$txtnm'];
    echo $kal;  
    $a++;
}
}
?>

<html>
<body>
<form action="exa.php" method="get">
<input type="text" name="n"/><br/>
<input type="submit" value="OK" name="ok"/>
</form>
</body>
</html>

Here I am getting an error saying 'undefined index $txtnm'

All things are on the same page, so you will get that warning. Use it like if(isset($_GET[$txtnm])) { $kal = $_GET[$txtnm]; echo $kal }. You should first check if there is $_GET[$txtnm] element or not — Altaf Hussain

here i am getting error that undefined index $txtnm ...

$kal=$_GET[$txtnm];

remove the single quotes, you are treating it as constant if you put those single quotes

Try to do like this

echo 'Input '.$a.'<input type="text" name="kal[]"/> <br/>';

and after submitting form the kal array like

print_r($_REQUEST['kal']);

And why you are using get method,without specific need dont use get method while submitting the textarea data,because some of special characters causes your redirect

Remove single quote from $kal=$_GET['$txtnm'] . It should be

   $kal=$_GET[$txtnm];
