PHP Autofill Without MySQL Database

xenowing · August 19, 2010

Hello playERZ'

So, I have a dinky contact form that validates and uses:

<form name="infoget" action="<?=$_SERVER['PHP_SELF']?>" method="post">

to validate the form via an external validate.php, then generate the email.

Finally:

// Send the mail using PHPs mail() function
mail($to, $subject, $body);
header("Location:customize_search.php");

So, this takes the user to a more advanced form after they 'send' the first form.

1 - Is it possible to have the second form autofill with the POSTed data and NOT use MySQL or database whatever?

2 - If so, how??

jcbones · August 19, 2010

1. Yes.

2. return the posted data to the page.

NOTE, the first code section you posted, says that the form is posting to it's own page. Putting the mail function at the top of that page with a few data checks is all you need to easily post the data back to the form. If you post your entire script, then we can get it sorted for you fairly quickly.

8)Thanks for the superfast reply

I hope what I post below is what you are asking for.

If you need more just let a brother know!

$errors = array(); // set the errors array to empty, by default
$fields = array(); // stores the field values
$success_message = "";

if (isset($_POST['submit']))
{
  // import the validation library
  require("validation.php");

  $rules = array(); // stores the validation rules

  // standard form fields
  $rules[] = "required,first_name,Enter your name.";
  $rules[] = "required,email,Enter your email address.";
  $rules[] = "valid_email,email,Please enter a valid email address.";

// Length of field input
  $rules[] = "length=10,phone,Please enter a ten digit Phone number.";

  $errors = validateFields($_POST, $rules);

  // if there were errors, re-populate the form fields
  if (!empty($errors))
  {  
    $fields = $_POST;
  }
  
  // no errors! redirect the user to the thankyou page (or whatever)
  else 
  {
    $message = "All fields have been validated successfully!";
    
    // here you would either email the form contents to someone or store it in a database. 
    // To redirect to a "thankyou" page, you'd just do this:
    $to = "info@fieldsof.corn";
$subject = "Most Amazing Email Form Ever";
$field_first = $_POST['first_name'];
$field_email = $_POST['email'];
$field_phone = $_POST['phone'];

$body = "Name: $field_first\n Email: $field_email\n Phone: $field_phone\n ";

// Send the mail using PHPs mail() function
mail($to, $subject, $body);
header("Location:customize_search.php");
  }
}

Then the form starts:

      <form name="infoget" action="<?=$_SERVER['PHP_SELF']?>" method="post">
        <fieldset>

Then inside the form, I'm using:

    // if $errors is not empty, the form must have failed one or more validation 
    // tests. Loop through each and display them on the page for the user
    if (!empty($errors))
    {
      echo "<div class='error' style='width:90%;'>Please fix the following errors:\n<ul>";
      foreach ($errors as $error)
        echo "<li>$error</li>\n";
    
      echo "</ul></div>"; 
    }
    
    if (!empty($message))
    {
      echo "<div class='notify'>$success_message</div>";
    }

Then a little bit of this:

            <label for="first_name">Name &#42;
              <input type="text" name="first_name" id="first_name" value="<?=$_POST['first_name']?>" />
            </label>

And finally:

<input class="button" type="image" name="submit" id="submit" value="submit" src="images/send.gif" width="192" height="69" />
            <input type="hidden" name="submit" value="submit" />

I guess I should have mentioned that the second pages basically uses the same setup as the first.

Pikachu2000 · August 19, 2010

Sort of unrelated, but change the form's action to action="" if you're submitting it to itself. Using $_SERVER['PHP_SELF'] is an XSS risk.

xenowing · August 19, 2010

I'm not sure I understand.

Do you mean remove Method and Name?

And just use the Action?? :confused:

Pikachu2000 · August 19, 2010

No, I mean remove $_SERVER['PHP_SELF'] from the <form tag and leave everything else.

xenowing · August 19, 2010

@ Pikachu2000

LOL. Oh! You meant what you typed, go figure

It seems to be working fine.

So, why would some crazy joker say I should put that PHP_SELF nonsense in the file - Although, I might have found it in a thread from 2004... who knows??

Pikachu2000 · August 19, 2010

Unfortunately, it still shows up in some current books and tutorials, even though it shouldn't . . .

jcbones · August 19, 2010

You are looking to put the posted data into the form on the "customize_search.php" page?

You could pass them onto that page in one of two ways.

1. Set them to session variables.

2. pass them as Get parameters inside the Location url.

xenowing · August 20, 2010

Okay, well I've tested a simple 2-page setup for passing data from one page to another to test to see if everything is configured properly, and it seems to work.

I just can't figure it out for my situation...

session_start(); // start PHP session to pass temp variables to next page 
$_SESSION['email']; // store session data
$_SESSION['phone']; // store session data

$errors = array(); // set the errors array to empty, by default
$fields = array(); // stores the field values
$success_message = "";

if (isset($_POST['submit']))
{
  // import the validation library
  require("validation.php");

  $rules = array(); // stores the validation rules

  // standard form fields
  $rules[] = "required,first_name,Enter your name.";
  $rules[] = "required,email,Enter your email address.";
  $rules[] = "valid_email,email,Please enter a valid email address.";

// Length of field input
  $rules[] = "length=10,phone,Please enter a ten digit Phone number.";

  $errors = validateFields($_POST, $rules);

  // if there were errors, re-populate the form fields

/*--------------------------------------------------------------------------------------------*\
  Function: validateFields()
  Purpose:  generic form field validation.
  Parameters: field - the POST / GET fields from a form which need to be validated.
              rules - an array of the validation rules. Each rule is a string of the form:

   "[if:FIELDNAME=VALUE,]REQUIREMENT,fieldname[,fieldname2 [,fieldname3, date_flag]],error message"
  
              if:FIELDNAME=VALUE,   This allows us to only validate a field 
                          only if a fieldname FIELDNAME has a value VALUE. This 
                          option allows for nesting; i.e. you can have multiple 
                          if clauses, separated by a comma. They will be examined
                          in the order in which they appear in the line.

              Valid REQUIREMENT strings are: 
                "required"     - field must be filled in
                "digits_only"  - field must contain digits only
                "is_alpha"     - field must only contain alphanumeric characters (0-9, a-Z)
                "custom_alpha" - field must be of the custom format specified.
                      fieldname:  the name of the field
                      fieldname2: a character or sequence of special characters. These characters are:
                          L   An uppercase Letter.          V   An uppercase Vowel.
                          l   A lowercase letter.           v   A lowercase vowel.
                          D   A letter (upper or lower).    F   A vowel (upper or lower).
                          C   An uppercase Consonant.       x   Any number, 0-9.
                          c   A lowercase consonant.        X   Any number, 1-9.
                          E   A consonant (upper or lower).
                "reg_exp"      - field must match the supplied regular expression.  
                      fieldname:  the name of the field
                      fieldname2: the regular expression
                      fieldname3: (optional) flags for the reg exp (like i for case insensitive
                "letters_only" - field must only contains letters (a-Z)

                "length=X"     - field has to be X characters long

  Comments:   With both digits_only, valid_email and is_alpha options, if the empty string is passed 
              in it won't generate an error, thus allowing validation of non-required fields. So,
              for example, if you want a field to be a valid email address, provide validation for 
              both "required" and "valid_email".
