Help => Script Not Working

[sleepingdanny]

<?
function emptyform(){
if($username=="" || $password==""){
print "You Have To Write Both Of Your Username And Password!<br><br>";}
}
?>

How do I write...
<input type="submit" value="Login" onClick="emptyform()"> Or how ??

Are you trying to call the function emptyForm() when a user clicks the submit button? If so you'll need to write the function in Javascript.

Ok the HTML should be something like:

<input type="text" name="username">
<input type="submit" name="submit">

Then the php:

<?
if (isset($_POST['submit'])){
emptyform();
}
else{
}

function emptyform(){

if($_POST['username']=="" || $_POST['password']==""){

print "You Have To Write Both Of Your Username And Password!<br><br>";}

}

?>

You cant do it that way with PHP, you have to either use Javascript or check the inputted values on another page.

Yes, the only way to do that would be to write the function in Javascript. There's probably a post on the Javascript forum that'll tell you how do do it. If not try searching for it.
