PHP/HTML form processing

2018-06-24 19:56:00

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"]; } } ?>

php code:

<?php
if (count($_POST) > 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<br/>";
}
echo "<a href='HTMLform.html'> Go Back</a>";
}
 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"];
 }

}
 ?>

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');

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

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?
