Hi! I'm new to PHP so apologies if I'm asking noob-like questions. I wrote out and ran the following code and received an error on line 37. Unfortunately, using terminal to debug is inefficient. Any help would be appreciated!..:

 

 

<!DOCTYPE html PUBLIC

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<title>Save Invoice</title>

<link rel="stylesheet" href="php_styles.css" type="text/css" />

<meta http-equiv="content-type"

content="text/html; charset=iso-8859-1" />

</head>

<body>

<?php

$BillTo = $_POST["billto"];

$Date = $_POST["date"];

$Terms = $_POST["terms"];

$Description1 = $_POST["description1"];

$Description2 = $_POST["description2"];

$Description3 = $_POST["description3"];

$InvoiceNum = $_POST["invoicenum"];

$Quantity1 = $_POST["quantity1"];

$Quantity2 = $_POST["quantity2"];

$Quantity3 = $_POST["quantity3"];

$Rate1 = $_POST["rate1"];

$Rate2 = $_POST["rate2"];

$Rate3 = $_POST["rate3"];

$Amount1 = $_POST["amount1"];

$Amount2 = $_POST["amount2"];

$Amount3 = $_POST["amount3"];

$Total = $_POST["total"];

if (empty($BillTo) ||
empty($Date) ||
empty($Terms) ||
empty($Description1) ||
empty($Description2) ||
empty($Description3) ||
echo "<hr/><p>You must enter a value in each field. Click your browser's Back button to return to the invoice.</p><hr />";
else if (!is_numeric($InvoiceNum) ||
!is_numeric($Quantity1) ||
!is_numeric($Quantity2) ||
!is_numeric($Quantity3) ||
!is_numeric($Rate1) ||
!is_numeric($Rate2) ||
!is_numeric($Rate3) ||
!is_numeric($Amount1) ||
!is_numeric($Amount2) ||
!is_numeric($Amount3) ||
!is_numeric($Total))
echo "<p>You have an error! Please click on your browser's Back button to return to the form.</p>";
	else {
	$InvoiceFile = fopen($InvoiceNum . ".txt", "w") ;
	echo "<h1>Invoice Saved</h1>";

	echo "<hr /><br /><table frame='border' rules='rows'>";

	echo "<tr><td><strong>Bill To</strong>";

	echo "<pre>$BillTo</pre></td>";

	echo "<td style='text-align: right' colspan='3'>";

	echo "<br /><strong>Invoice #</strong>: $InvoiceNum<br />";

	echo "<strong>Date</strong>: $Date<br />";

	echo "<strong>Terms</strong>: $Terms</td></tr>";

	echo "<tr>";

	echo "<td><strong>Description</strong><br />$Description1<br />$Description2<br />$Description3</td>";

	echo "<td style='text-align: right'><strong>Quantity</strong><br />$Quantity1<br />$Quantity2<br />$Quantity3</td>";

	echo "<td style='text-align: right'><strong>Rate</strong><br />$$Rate1<br />$$Rate2<br />$$Rate3</td>";

	echo "<td style='text-align: right'><strong>Amount</strong><br />$$Amount1<br />$$Amount2<br />$$Amount3</td></tr>";

	echo "<tr><td colspan='4' style='text-align: right'><strong>TOTAL</strong>: $$Total</td></tr>";

	echo "</table>";

?>

<hr />

You dont close the if:

if (empty($BillTo) ||
empty($Date) ||
empty($Terms) ||
empty($Description1) ||
empty($Description2) ||
empty($Description3) ||
echo "<hr/><p>You must enter a value in each field. Click your browser's Back button to return to the invoice.</p><hr />";
//...

 

Also, you don't close your last else statement.

using terminal to debug is inefficient
You should be developing and debugging code on a local PC that has a web server, php, and if needed mysql. These can be installed individually (for those wanting to learn how), or as a package - http://www.apachefriends.org/en/xampp.html

 

Posting the actual error would help someone to be able to help you.

I'm guessing you still didn't close that first statement correctly.
