Your submit button doesn t have a name  Add name  submit  to your submit button    If you view source on the form in the browser  you ll see how it submits to self - the form s action attribute will contain the name of the current script - therefore when the form submits  it submits to itself  Edit for vanity sake

That will only work if register globals is on  and it should never be on  unless of course you are defining that variable somewhere else    Try setting the form s action attribute to        lt form method  post  action     gt          lt  form gt    You can also set it to be blank       but older WebKit versions had a bug

I guess   you means   SERVER  PHP SELF    And if so   you really shouldn t use it without sanitizing it first   This leaves you open to XSS attacks   The if isset   POST  submit     condition should be above all the HTML output  and should contain a header   function with a redirect to current page again  only now   with some nice notice that  emails has been sent     or something    For that you will have to use   SESSION or   COOKIE   And please  Stop using   REQUEST  It too poses a security threat

change  lt input type  submit  value  Submit    gt  to  lt input type  submit  value  Submit  name  submit   gt  change  lt form method  post  action   lt  php echo  PHP SELF   gt   gt  to  lt form method  post  action    gt  It will perform the code in if only when it is submitted  It will always show the form  html code   what exactly is your question

The proper way would be to use   SERVER  PHP SELF    in conjunction with htmlspecialchars to avoid possible exploits   You can also just skip the action  part empty  which is not W3C valid  but currently works in most  all   browsers - the default is to submit to self if it s empty   Here is an example form that takes a name and email  and then displays the values you have entered upon submit    lt  php if   empty   POST      gt      Welcome   lt  php echo htmlspecialchars   POST  name       gt   lt br gt      Your email is  lt  php echo htmlspecialchars   POST  email       gt   lt br gt   lt  php else    gt       lt form action   lt  php echo htmlspecialchars   SERVER  PHP SELF       gt   method  post  gt          Name   lt input type  text  name  name  gt  lt br gt          Email   lt input type  text  name  email  gt  lt br gt           lt input type  submit  gt       lt  form gt   lt  php endif    gt
