functions vs. includes

mikecrumm

I am having some difficulty in using functions. If I use the following code with an include() command, it works just fine, but if i declare it in a function and call the function, it does not work. An anyone explain?

Here's the code:
if (!isset($name)&&!isset($email)){
echo "<br><font size=+1>Add User</font>";
echo "<table border=1 bordercolor=\"#000000\" align=\"center\" cellpadding=0 cellspacing=0 width=50%>";
echo "<form method=post action=\"index.php?page=add\">";
echo "<tr><td align=\"center\">Name:</td><td align=\"left\"> <input type=text name=name class=input1></td></tr><tr><td align=\"center\">Email:</td><td align=\"left\"> <input type=text name=email class=input1> <input type=image src=\"ok.gif\"></td></tr></form></table>";}
else {
$Query = "INSERT INTO phpmailer VALUES(NULL,NULL,'$name','$email')";
$Results = mysql_query($Query);
echo "<br><p>Successfully Added $name & $email to the databse.";}

You probably have an issue with globals and forgetting to declare variables as global inside the function.

Be aware that if someone doesn't fill in a value a form text element, the element is still set--it just doesn't have any value, but it's set because the NAME of the element was passed.

A great way to see is a form has been submitted is using $HTTP_POST_VARS. It's always there even on pages without forms but its size will vary.

if(sizeof($HTTP_POST_VARS > 0){//you have a form submission present}else{//you don't}
