Question

How to retrieve this one :

<form name="payform" method="POST" action="payment.php">
<?php
echo '<INPUT TYPE="text" NAME="eg_payamt_' . $record_count. '" Value="' . $amount_dueArr[$record_count] . '" size="10"><br>';                    
?>    
</form>

in payment.php

<?

$total_pay=$_POST["totalNS"];

echo "Payment gateway simulation! <br>";
echo "Mode : ".$mode."<br>";
echo "Total Payment : ".$total_pay."<br>";

?>

how can I retrieve :

 echo '<INPUT TYPE="text" NAME="eg_payamt_' . $record_count. '" Value="' . $amount_dueArr[$record_count] . '" size="10"><br>';                    

in payment php how can I write $payment =_POST[eg_payamt_ ?????]

Payment.php, updated with vardump ?

<?php
$mode=$_POST["eg_mode"];
$total_pay=$_POST["totalNS"];
$record_count=$_POST["record"];
$desc=$_POST["eg_desc_".$record_count];
$payamt = $_POST['$eg_payamt_'. $record_count]; 

$k=$record_count=$_POST["record"];

foreach($_POST as $k => $v){
  if(strpos('eg_payamt_', $k) === 0){
    echo "$k => $v
";
  }
}
echo var_dump($payments);


echo "Payment gateway simulation! <br>";
echo "Mode : ".$mode."<br>";
echo "Total Payment : ".$total_pay."<br>";
echo "Record count : ".$record_count."<br>";

?>

how can I use vardump ?? how can I retrieve pay_amt with vardump ?

echo '<INPUT TYPE="text" NAME="eg_payamt_' . $record_count. '"
Value="' . $amount_dueArr[$record_count] . '" size="10"><br>';

any ideas to get multiple _POST which are being passed??

Answer 1

can do like this

in the form, add another hidden value inside the form to be passed to payment.php

<input type="hidden" name="record_count" value="<? echo $record_count ?>" />

and in payment.php :

$record_count = $_POST['record_count'];
$eg_payamt = $_POST['$eg_payamt_'. $record_count];
