So what is your question? Does the above not work? What does it do? What doesn't it do?

[mikesta707]

if(isset($_POST['Submit'])){
if($_POST['host'] =="") {
echo"Please Fill Out the Host Filed";

}
if($_POST['user'] =="") {
echo"<br>Please fill Out the Username Filed";
}
if($_POST['pass'] =="") {
echo"<br>Please Fill Out the Password";
}
if($_POST['db_name'] =="") {
echo"<br>please fill Out the Databases name";
}

 

You want to exit the script when those if statements run true. if you don't, as it is now, it will just tell you you should fill out what ever field, but still do the query.

 

if(isset($_POST['Submit'])){
if($_POST['host'] =="") {
echo"Please Fill Out the Host Filed";
exit();
}
if($_POST['user'] =="") {
echo"<br>Please fill Out the Username Filed";
exit();
}
if($_POST['pass'] =="") {
echo"<br>Please Fill Out the Password";
exit();
}
if($_POST['db_name'] =="") {
echo"<br>please fill Out the Databases name";
exit();
}

 

you could also do something like

$error = false;
if(isset($_POST['Submit'])){
if($_POST['host'] =="") {
echo"Please Fill Out the Host Filed";
$error = true;
}
if($_POST['user'] =="") {
echo"<br>Please fill Out the Username Filed";
$error = true;
}
if($_POST['pass'] =="") {
echo"<br>Please Fill Out the Password";
$error = true;
}
if($_POST['db_name'] =="") {
echo"<br>please fill Out the Databases name";
$error = true;
}

if ($error){
exit();
}

if you wanted to get all the error messages

it works but if the 4 fields form the form are not filled out is tell them to go back and fix it but it still make the file db.php i want it to check to see if they are filled out if they are then make the file if not tell them to go back
