PHP/HTML form processing

Question

The assignment is to create an html form where the user enters the required information, and process the form data via PHP to display the output using $_post method. I can't seem to get the output right, it just basically displays the php code that I wrote. any insight is greatly appreciated Note: The html code is lengthy, but I'm sure it's correct. My problem is with the PHP(next) code. the following is the output:

0){ $Name = trim($_POST['name']); $adr = trim($_POST['address']); $City = trim($_POST['city']); $state = trim($_POST['state']); $zip = trim($_POST['zip']); $phone = trim($_POST['phone']); $email = trim($_POST['email']); $err = array(); if($Name == ''){ $err[] = "Please enter your name"; } if($adr == ''){ $err[] = "Please enter your address"; } if($City == ''){ $err[] = "Please enter your city"; } if($state == ''){ $err[] = "Please enter your State"; } if($zip == ''){ $err[] = "Please enter your zip"; } if($phone == ''){ $err[] = "Please enter your phone number"; } if($email == ''){ $err[] = "Please enter your email"; } if(count($err) > 0){ foreach($err as $value){ echo"$value
"; } echo " Go Back"; } else{ //header("Location:HTMLform.html"); echo "Name: " . $_POST["name"]; echo "Address: " . $_POST["address"] ; echo "City: " . $_POST["city"] ; echo "State: " . $_POST["state"]; echo "Zip: " . $_POST["zip"]; echo "Phone: " . $_POST["phone"]; echo "Email: " . $_POST["email"]; } } ?>

Answer 1

PHP file are saved with .php extension and has an opening of
PHP code should be at the top of the page, before any HTML tag
Instead of using $variable == '' to check if it's empty, use function called empty($variable) that return true if empty
You are doing a redirect in the first line of the else statement, so the rest of the code won't be executed, therefore the echo part will never be reached. Put this header("Location:HTMLform.html"); as the last statement in the else scope

Answer 2

You have some errors in your code.

There is a space between <? tag and php in line 1. Remove that
There is no closing curly brace for this , if (count($_POST) > 0) { . Add a closing curly brace before the ending ?> tag.
You have the name field of telephone set to 'phone'.
So find all lines having this
```
  $_POST['telephone'] 
```
and change it to
```
  $_POST['phone'] 
```

Also, If you want to see the results, comment out

  header('Location:HTMLForm.html');

old

// is this suppose to be an array?
    $err = array();
    if($_POST['name'] == null){
        array_push($err,'error stuff stuff stuff');
    }
    print_r($err);

// if not array
    $err = '';
    if($_POST['name'] == null){
        $err.= 'error stuff stuff stuff';
    }

Also, What are you trimming from the post?
