a doubt on $_POST['SUBMIT']...

[blueeyes4ya]

i have a small query on usage of $_POST[' ']...i have a submit button..its just a registration form and after filling all fields, i check whether the button has been submitted and write all operations inside that...i will write a small example of what i did..

//all form in html here 
<?php 
   if (isset($_POST['submit'])){
    if(empty(.......cheking whether any field is empty...){
     printing missing field
    }
    echo " helllo....";
}
   else{
      //   
    }
?>

The problem is for the first time when i submit , hello will be displayed..next time if i load the page , hello will be display before i submit.Do i need to unset something here each time i load the page???Please help...

No. Are you sure you are not just refreshing the page. This will resubmit the form.

Where is the form going after you hit submit? If you have it change location I doubt it will say hello

<?
if($_POST["submit"]!=NULL){
if($_POST["username"]!=NULL&&$_POST["password"]!=NULL){
//username and/or password is filled
}else{
//send person back to form or something....  
}

}
?>
