thx in advance for any help on this. I've created an email invite form but the code won't let you sent the invite unless the form starts with a comma. Commas are used in the code to separate email addresses but I can't seem to figure out how to send the form without first having a comma. Here is the code. Many thanks.
//if
else{
global $main_url;
//getting values
$emails=form_get("emails");
$subject=form_get("subject");
$mes=form_get("mes");
$emails=ereg_replace("\r","",$emails);
$emails=ereg_replace("\n","",$emails);
$emails=ereg_replace(" ","",$emails);
$email=",".$email;
$email=split(",",$emails);
$email=if_empty($email);
$data[0]=$subject;
$now=time();
if($email!=''){
show_header();
echo "<table width=100% class='body'>
<tr><td class='lined title'>Invitation</td>
<tr><td class='lined'>";
foreach($email as $addr){
//if user is site member - standart invitation
$sql_query2="select mem_id from members where email='$addr'";
$num=sql_execute($sql_query2,'num');

$fr=sql_execute($sql_query2,'get');
