been getting this message ever since i install php4 on my home pc. it does not have this problem when i boot up the same files on my previous office computer.

error
=====
PHP Notice: Undefined index: actionflag in D:\SAV\login.php on line 7 PHP Notice: Undefined index: Userid in D:\SAV\login.php on line 8 PHP Notice: Undefined index: Password in D:\SAV\login.php on line 9

i mean i have this on my login page at the begining

Code
====
<?php
   include("includes/dblib.inc");
   include("includes/clublib.inc");

    $message="";

    $actionflag = $_POST['actionflag'];
    $Userid = $_POST['Userid'];
    $password = $_POST['Password'];

.. more codes ..
?>

i was thinking whether is it good to turn off error reporting?
error_reporting = E_ALL

i don't have this problem previously.
Can some 1 guide mw as to wat is causing this problems?

thanks.

Replace those assignment lines with something like this:

$actionflag = (isset($_POST['actionflag']))? $_POST['actionflag'] : "";

Where will you be in 100 years?

Certainly Error reporting is the issue. It's not really an error. It's just a NOTICE. Basically it's saying that you looked for a variable in an array (THe array is the $_POST array) and the index specified was not found. Thus the value for that INDEX was not sent.

As SNIB points out, you could use the ISSET in a tertiary function. I like to use the !empty() i.e. :

$actionflag = !empty($_POST['actionflag'])? $_POST['actionflag'] : "";

This is the same as :

if (!empty ($_POST['actionflag'])) {
      $actionflag = $_POST['actionflag'];
  } else {
      $actionflag = "";
  }

hi snib and peg110,

i did this and everything was okay

error_reporting = E_ALL & ~E_NOTICE

but i doubt its the correct way. It simply ignore all the notice which peg110 have pointed out.

snib, if i were to post back a dozen of then variables, for examples a update particulars form, then i will need to do all those isset checking?

from my form

    $actionflag = $_POST['actionflag'];
    $savid = $_POST['savid'];
    $surname = $_POST['surname'];
    $givenname = $_POST['givenname'];
    $dob = $_POST['dob'];
    $datepass = $_POST['datepass'];
    $nric = $_POST['nric'];
    $telhome = $_POST['telhome'];
    $telmobile = $_POST['telmobile'];
    $************ = $_POST['************'];
    $email = $_POST['email'];
    $addr1 = $_POST['addr1'];
    $addr2 = $_POST['addr2'];
    $addr3 = $_POST['addr3'];
    $pcode = $_POST['pcode'];

    $day = $_POST['day'];
    $month = $_POST['month'];
    $year = $_POST['year'];

thx.

Well actually, since it appears you are just creating easier to type variables (from the Super Global Array of $_POST ), you could do what I often like to do.


    foreach ($_POST as $index => $content) {
        $$index = $content; //note the DOUBLE $ for $$index
   }


This will take a LONG list of POSTed variables and convert them into a local variable with the same name as the index. It will also avoid the ISSET since it will only create a local variable if it was POSTed.
