javascript - php show login status message does not update -

I am trying to display a status message when someone tries to log me in. The problem I have is:

• After checking the login, and it does not match, this output does not $ loginStatusMessage == "does not match" Is but not within HTML (which I like because it is wrapped in CSS styling tag).
• Instead, HTML $ loginStatusMessage echos "welcome" even after the variable is updated.

  I'm guessing because PHP is called to run only after the form, re-sms reload message with this $ login? How do I create it so that HTML changes $ loginStatusMessage to when I submit the form

  I have a global variable $ Login status message

    $ loginStatusMessage = "welcome"; If (isset ($ _ POST ['submit'])) {login ($ user name, $ password); } Function login ($ username, $ password) {if (check! Login ($ username, $ password)) {$ loginStatusMessage = "does not match ..."; Echo $ loginstats messages; } And {session_start ();   
    This output outputs:   "does not match" , but not inside the body in HTML  
   
   But in my body, I have:  
    & lt; P class = 'loginMsg' & gt; & Lt ;? Php; Echo $ loginStatusMessage; ? & Gt; & Lt; / P & gt;   
    This gives echo output:   "welcome"   
   so when I submit the form I call it File:  
    & lt; Form id = 'register' action = "& lt ;? php echo $ _SERVER ['PHP_SELF'] ;? & gt;" Method = 'post' accept-charset = 'UTF-8' & gt;    
   
   
   declare variable  
    $ loginStatusMessage;   
   And then if your "verification" verification in your code then  
    $ loginStatusMessage = "welcome";   
   if not  
    $ login statusMessage = "do not match";   
   In this section, you will need to print the variable to do this:  
      
   Hope it helps
