Question

So Im relatively new to PHP from ASP. And After converting alot of ASP code into PHP I have come across a problem where my PHP code seems unable to find the hidden variable I have set. It worked fine in ASP and was just wondering the best way to resolve this.

Start of the Form:

<form name="LogIn" action="login.php" method="post">
                    <td bgColor=#ffffff>
                        <table align="center" cellSpacing="2" cellPadding="2" border="0">
                            <tr>
                                <td>&nbsp;</td>
                                <td align="right"><font color="#4d71a1">User name:</font>&nbsp;</td>
                                <td><input name="UserName" size="25" type="Text" autocomplete="OFF"></td>
                                <td>&nbsp;</td>
                            </tr>
                            <tr>
                                <td>&nbsp;</td>
                                <td align="right"><font color="#4d71a1">Password:</font>&nbsp;</td>
                                <td><input name="Password" size="25" type="Password" autocomplete="OFF"></td>
                                <td>&nbsp;</td>
                            </tr>

PHP script:

<? 
if ($_POST["BtnPress"]=="Pressed")
{

if ($_POST["Username"]=="*****" && $_POST["password"]=="*********")
{

$_SESSION['AdminID']="1";
header("Location: "."index.php");
}
  else
{

print "<font color=#ff0000>Sorry you cannot access this part of the site.</font>";
} 

} 
?> 

then the rest of the form:

<tr>
                                <td align="center" colspan="4">
                                    <input type="hidden" name="BtnPress" value="Pressed">
                                    <input type="Submit" value="Log In" class="mybutton" onclick="return CheckForm();">
                                </td>   
                            </tr>
                        </table>


                    </td>
                </form>

The PHP seems unable to find the variable BtnPress, its a similar problem throughout alot of my translated ASP to PHP script. Sorry if it is a simple solution but can anyone tell me where I am going wrong?

Do not use a hidden input to test if a form is submitted.

use:

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
  // processing of $_POST
}
