没有在PHP中获得所需的输出

Question

My code looks completely correct.I just copied it from New Boston php tutorial,its working there. But its not working properly here. Every time after the submission else block get executed and it produces the output "Please fill the form". If I filled all the fields than if block should get executed, and it should print the 'contact_name', 'contact_email', 'contact_text', but its not.I am writing this code in netbeans.

here is the code:

<?php
    if(isset($_POST['contact_name']) && isset($_POST['contact_email'])
    isset($_POST['contact_text']))
    {
        echo $contact_name=$_POST['contact_name'];
        echo $contact_email=$_POST['contact_email'];
        echo $contact_text=$_POST['contact_text'];
    }
    else
    {
        echo 'Please fill the form';
    }
?>

<form action="index.php" method="POST">
    Name:<br><input type="text" name="=contact_name"><br><br>
    Email address:<br><input type="text" name="contact_email"><br><br>
    Message:<br>
    <textarea name="contact_text" rows="6" cols="30"></textarea><br><br>
    <input type="submit" value="Send">
</form>

Answer 1

Replace

  Name:<br><input type="text" name="=contact_name"><br><br>

With

  Name:<br><input type="text" name="contact_name"><br><br>
