Hi,

I would like to loop though posted values and format them to nnnnn.nn, if current value is 0 or null then set $itemPrice[$key] equal to previous value, if no previous value then set to 99.99

for example if the following where submited, $str would be equal to '12.34,1999.47,1999.47,1999.47';

$itemPrice[0] = "12.34";
$itemPrice[1] = "1999.4678";
$itemPrice[2] = "0";
$itemPrice[3] = "";

for example if the following where submitted, $str would be equal to '99.99,19.48,12.30,12.30';

$itemPrice[0] = "";
$itemPrice[1] = "19.48";
$itemPrice[2] = "12.3";
$itemPrice[3] = "";

I hope that makes sense.

Thanks in advance for your feedback.

<?php error_reporting(E_ALL);

setlocale(LC_MONETARY, 'en_US');

if ((isset($_POST["update_form"])) && ($_POST["update_form"] == "Y")) {

		
	 //strip non dollar charaters and
	 $itemPrice = preg_replace("/[^0-9.]/", "", $_POST['itemPrice']);
		
		foreach ($itemPrice as $key => $val){
			if ($val == NULL) $itemPrice[$key] = '99.99';
		}
		
		// COLLAPSE THE ARRAY INTO COMMA-SEPARATED VALUES
		$str = implode(',', $itemPrice);
		var_dump($str);
		

}


$itemPrice[0] = "12.34";
$itemPrice[1] = "1999.4";
$itemPrice[2] = "0";
$itemPrice[3] = "";

?>
<html>
<head>
<title>Test</title>
</head>

<body>

<form id="form1" name="form1" method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?> ">
            Normal Price 1&nbsp;<input name="itemPrice[]" type="text" id="itemPrice" value="<?php  if ($itemPrice[0] > 0) echo money_format('%(#6n',$itemPrice[0]); ?>" size="8"><br>
            Normal Price 2&nbsp;<input name="itemPrice[]" type="text" id="itemPrice" value="<?php if ($itemPrice[1] > 0)  echo money_format('%(#6n',$itemPrice[1]); ?>" size="8"><br>
            Normal Price 3&nbsp;<input name="itemPrice[]" type="text" id="itemPrice" value="<?php if ($itemPrice[2] > 0)  echo money_format('%(#6n',$itemPrice[2]); ?>" size="8"><br>
            Normal Price 4&nbsp;<input name="itemPrice[]" type="text" id="itemPrice" value="<?php if ($itemPrice[3] > 0)  echo money_format('%(#6n',$itemPrice[3]); ?>" size="8"><br>
 
  <input name="update_form" type="hidden" id="update_form" value="Y">
  <input name="Update Prices" type="submit">

Please see: http://iconoun.com/demo/temp_sabecs.php

Note that this mungs the input array, so you might want to copy it before injecting it into the foreach() loop.

<?php // demo/temp_sabecs.php
error_reporting(E_ALL);

 *
 * $itemPrice[0] = "12.34";
 * $itemPrice[1] = "1999.4678";
 * $itemPrice[2] = "0";
 * $itemPrice[3] = "";
 *
