I can t print the value of $_POST in my browser. This the form_methods.php:

<html>
    <head>
        <title>Form Methods</title>
    </head>
    <body>
        <form method="post" action="formoutputpage.php">
            <p><input type="text" name="greeting" size="15"></p>
            <p><input type="text" name="name" size="15"></p>
            <p><input type="submit" name="submit" value="Salutation"></p>
        </form>
    </body>
</html>

<代码>formoutputpage.php:

<?
    echo $_POST[ greeting ];
    echo " ".$_POST[ name ];
    echo "!";
?>

Answer 1

I think this code is OK. Check whether there is any error which is not displayed.
So insert this code top of formoutputpage.php that exactly display all errors.

<?php
  ini_set(  display_errors , 1 );
  error_reporting(E_ALL);
?>

And check short tag is allowed. <? => <?php
Parse error may not be displayed depending on your configration.

try this

<html>
    <head>
        <title>Form Methods</title>
    </head>
    <body>
        <form method="post" action="Formoutputpage.php">
            <input type="text" name="greeting" size="15" />
            <input type="text" name="name" size="15" />
            <input type="submit" name="submit" value="Salutation" />
        </form>
    </body>
</html>

Formoutputpage.php

<?php
     if(isset($_POST[ submit ])){
        echo $_POST[ greeting ] . " " . $_POST[ name ] . "!";
     }else{
        //do whatever you want
     }
?>
