PHP Form with internal pages/id

[Sasso]

Hi anyone,

First of all congratulations on this wonderful forum!

I’m looking for a solution for a multipage php form . I’d to know how to pass vars from a page to the other. I’ve tried using hidden fields and sessions but don’t work. My problem is that pages are just ids inside in a single page.

I’d to make in any page that links to the next and in the last page a button to send the form (it’s easy but I cannot get vars from previous pages, so it gives errors for blank fields.

This is the code (I’ve dumb down it to understand better the problem):

PHP Code:

<?
$id=$_GET[id];

// ################### CONFIG ###################

$class_txt = "text";
$class_inputbutton = "inputButton";
$class_inputline = "inputLine";
$class_inputfield = "inputField";
$style_inputline = "width:355px;";
$style_inputfield = "width:355px;";

// email
$target_address = "info@email.it";
$email_subject = "Oggetto";

// error messages
$err_name =    "name";
$err_email = "e-mail";
$err_tit = "title";

// misc text
$msg_date = "Date";
$msg_name = "Name";
$msg_email = "Email:";
$msg_tit = "Title ";

$txt_send = "Send";
$txt_mandatory = "required";

$msg_indent = 11;

// messages
$txt_thankyou = "<div class='$class_txt'><h2>Thank you!</h2></div>";
$txt_error = "<div style='color: #cc3300' class='$class_txt'><h2>Error! Check the follow fields:</h2>{errors}</div>";    // {errors} is replaced by the errors that occurred

// ################ END  CONFIG #################

function spaces($num, $fill=" "){
    $foo="";
    for ($i=0; $i<$num; $i++) $foo.=$fill;
    return $foo;
}

function isValidEmail($addr){
    if(eregi("^[a-z0-9]+([_.-][a-z0-9]+)*@([a-z0-9]+([.-][a-z0-9]+)*)+\.[a-z]{2,4}$", $addr))
        return true;
    else
        return false;
}


// start form evaluation
$error="foo";
if ($_REQUEST['do']=="send"){
    $error=false;
    if ($_REQUEST['name']=="") $error.="&raquo; $err_name<br>";                     
    if ($_REQUEST['tit']=="") $error.="&raquo; $err_tit<br>";     


    if (!isValidEmail($_REQUEST['email'])) $error.="&raquo; $err_email<br>";
    if ($error===false){
    
        $message="$msg_date:".spaces($msg_indent-strlen($msg_date)).date("d M Y, H:i", time());
        if ($_REQUEST['name']) $message.="\n$msg_name:".spaces($msg_indent-strlen($msg_name)).$_REQUEST['name'];
        if ($_REQUEST['tit']) $message.="\n$msg_tit:".spaces($msg_indent-strlen($msg_tit)).$_REQUEST['tit'];        
      $message.="\n$msg_email:".spaces($msg_indent-strlen($msg_email))."mailto:".$_REQUEST['email'];
        $message.="\n\n$msg_request:\n\n".$_REQUEST['message'];
        
        mail($target_address, $email_subject, $message, "From: ".$_REQUEST['email']);
        echo $txt_thankyou;
        
    }else if ($error!==false) $error=str_replace("{errors}", $error, $txt_error);

}

if ($error!==false){

    if($error!="foo") echo $error;
    
    // form
    echo "<script language='JavaScript' type='text/JavaScript'>\n";
    echo "window.onload = function(){ document.form1.firma.focus(); }\n";
    echo "</script>\n";    

    echo "<form name='form1' method='post' action=''>\n";

    echo "<h2>FORM</h2>\n";            

    if ($id == '1')  {     
    echo "<table  border='0' class='txt'>\n";
    echo "<tr><td class='$class_txt'>$msg_name *</td>\n";
    echo "<td><input name='name' type='text' class='$class_inputline' style='$style_inputline' value='".$_REQUEST['name']."'>\n";
    echo "</td></tr>\n";    
    echo "</table>\n";   
  }    
  
    else if ($id == '2')  {     
    echo "<table  border='0' class='txt'>\n";
    echo "<tr><td class='$class_txt'>$msg_tit *</td>\n";
    echo "<td><input name='tit' type='text' class='$class_inputline' style='$style_inputline' value='".$_REQUEST['tit']."'>\n";
    echo "</td></tr>\n";    
    echo "</table>\n";   
  }    
    
  else {  
    echo "<table  border='0' class='txt'>\n";
    echo "<tr><td class='$class_txt'>$msg_email *</td>\n";
    echo "<td><input name='email' type='text' class='$class_inputline' style='$style_inputline' value='".$_REQUEST['email']."'>\n";
    echo "</td></tr>\n";
    echo "<tr><td><input name='Submit' type='Submit' class='$class_inputbutton' value='$txt_send'>\n";
    echo "<input name='do' type='hidden' id='do' value='send'></td>\n";
    echo "</tr>\n";       
    echo "</table>\n";    
}    

    echo "</form>\n";

}

?>

Here an example

PHP Code:

<?php
if (isset($_POST['submit'])) {
$var = $_POST['var'];
echo $var;
//other codes you want
} else {
?>
<title>Example</title>
<center><h1>Example</h1></center><br>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<center><h3>Example var:</h3>
<input type="text" name="var" maxlength="500"><br><br>
<input type="submit" name="submit" value="Submit">
</center>
</form>
<?php
}
?>

Basicly you use a normal html form and use $_POST['inputname'] to get the var you use $_SERVER['PHP_SELF'] to post to your own page and isset to know if you display the form or run the code.

Just a bit more ::: $_(method of form)
E.G
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
means its in $_POST

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="get">
means its in $_GET

OR the bad way
$_REQUEST
Is both $_GET and $_POST
