[RESOLVED] My PHP code is showing up underneath the executed code.

[chris1990]

I have spent the last couple of hours developing my code and it seems to be working fine. However i just noticed that the code had started showing up underneath the executed code, i have tried commenting out the lines of code i edited in the last half hour with no fix.

Im using wordpress 3.8 on a localhost.

<?php
[insert_php]
function IsPostcode($postcode){
	$postcode = strtoupper(str_replace(' ','',$postcode));
	if(preg_match("/^[A-Z]{1,2}[0-9]{2,3}[A-Z]{2}$/",$postcode) || preg_match("/^[A-Z]{1,2}[0-9]{1}[A-Z]{1}[0-9]{1}[A-Z]{2}$/",$postcode) || preg_match("/^GIR0[A-Z]{2}$/",$postcode))
	return true;
	else
	return false;
}

				
				$ORIGIN = $row[ORIGIN];
				//postcode
				if (IsPostcode($ORIGIN))
				{echo "<tr><td colspan=\"1\" class=\"bold\">Address:</td><td colspan=\"1\"><input type=\"text\" name=\"P_ADDRESS\"></td>";
				echo "<td colspan=\"1\" class=\"bold\">Postcode:</td><td colspan=\"1\"><input type=\"hidden\" name=\"P_POSTCODE\" value=\"".$row[ORIGIN]."\"><input type=\"text\" name=\"P_POSTCODE1\" value=\"".$row[ORIGIN]."\" disabled></td></tr>\n";}
				//airport
				else if (strpos($ORIGIN, "AIRPORT") !== FALSE){
				echo "<tr><td colspan=\"1\" class=\"bold\">Airport:</td><td colspan=\"3\"><input type=\"HIDDEN\" name=\"P_ADDRESS\" value=\"".$row[ORIGIN]."\"><input type=\"text\" name=\"P_ADDRESS1\" value=\"".$row[ORIGIN]."\"disabled></td></tr>\n";
