Multi-part one page PHP form help!

kranzoky

I have a long application form that I want to have on one page but displayed in stages (parts). I want to write this in PHP and have it so when the user fills out a specific section and clicks submit, the data is stored and the next part is displayed on the same page. Here is what I have so far and it is not working. I think I have the basic concept down but I need help. Ans also is there some kind of IE bug fix code for PHP sessions 9this is something I hear about)?

here is the html of my page:

<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>

<?php
$formnum = $POST['formnum'] + 1;
if ($formnum == 2) {
// process data from form 1
$inputa = $POST['inputa'];
$inputb = $POST['inputb'];
$SESSION['inputa'] = $inputa;
$SESSION['inputb'] = $inputb;
} elseif ($formnum == 3) {
// process data from form 2
$inputc = $POST['inputc'];
$_SESSION['inputc'];
}
?>
<?php
if ($formnum == 1) {
?>
<form name="form1" method="post">
<p>
<input name="Name" type="text" id="Name">
</p>
<p>
<input name="Email" type="text" id="Email">
</p>
<p>
<input name="Phone" type="text" id="Phone">
</p>
<input type="button" name="Next" value="Next">
</form>
<?php
} elseif ($formnum == 2) {
?>
<form name="form1" method="post">
<p>
<textarea name="Comment" id="Comment"></textarea>
</p>
<input type="button" name="Next" value="Next">
</form>
<?php
} elseif ($formnum == 2) {
?>
<form name="form1" method="post" action="form.php">
<p>
<input name="1" type="radio" value="radiobutton">
</p>
<p>
<input name="2" type="radio" value="radiobutton">
</p>
<p>
<input name="3" type="radio" value="radiobutton">
<input type="button" name="Next" value="Next">
</form>
</p>
<?php
}
?>
</body>
</html>

What am I doing wrong? I know I am pretty close but I need some help. Thanks in advance.

your not passing form num in form or sessions so it will allways be 1 as it is never set to anything apart from 1 at top of script

also your radio buttons values and names are wrong way round

kranzoky

How would I pass the form num? Also, I just through the form together for testing purposes so I know the radio buttons aren't correct.

the simplest way is to add a hidden field to each form named formnum

kranzoky

Here is the body of my page. I put in the hidden field and now it goes to the next part of the form, but it won't submit at the end. What am I doing wrong? Also if I added more sections (let's say 10 sections), how would I go about configuring the PHP to work with more sections... in other words what would I have to add?

Thank you for your help.. I am a not very experienced with PHP... as you can tell.

Here is my code:

sidney

try putting hidden value to 2 in second form

kranzoky

It still doesn't submit (post). Could it be something to do with where my html form tag is placed and whether the action to post to "form.php" should be within that tag or the last submit button?

Thanks,

sidney

i had to change the submit buttons to get it to submit example above

kranzoky

It submits now... but the fields from the first part of the form are not being sent when it is submitted?

This is what I have now, Is it becuause of where I have the action="form.php" located?

sidney

try this ive change a few thing and registered sessions to store each form and put some echos to see whats going on

 <?php   

session_start();
$_POST['formnum']++;
$formnum = $_POST['formnum'];

if ($formnum > 1)
{
echo "submited data<br>";
foreach($_POST as $key => $value)
{
if (!session_is_registered($key)) {
   session_register($key);}
 else { 
 $_SESSION[$key]=$value;}
echo $key." - ".$value."<br>";
}
echo"-----------------<br>";
}
echo"<form action=\"".$PHP_SELF."\" name=\"form$formnum\" method=\"post\">";
echo"<input name=\"formnum\" type=\"hidden\" value=\"$formnum\">"; 


if ($formnum == 3) 
{//edit here add form to take session array and send mail or post to another page or form 
echo "session data<br>";
// process data from form 2 
foreach($_SESSION as $k => $v)
{
echo $k." - ".$v."<br>";
}

} 
elseif ($formnum == 1) 
{ 
?> 
<p> 
<input name="Name" type="text" id="Name"> 
</p> 
<p> 
<input name="Email" type="text" id="Email"> 
</p> 
<p> 
<input name="Phone" type="text" id="Phone"> 
</p> 
<?php 
} 
elseif ($formnum == 2) 
{
?> 
<p>  

<input name="1" type="radio" value="radiobutton"> 
</p> 
<p> 
<input name="2" type="radio" value="radiobutton"> 
</p> 
<p> 
<input name="3" type="radio" value="radiobutton"> 
</p> 
<?php 
} 
else
{ echo"error";}
?>
<p> 
  <input type="submit" name="Submit" value="Submit"> 
</p>
</form>

kranzoky

I will try it out... How would I go about sending this information to an email address. Right now I am sending it to a PHP script "form.php" that formats it and sends it out in an email. Is this the easiest way? Where do I put the action to send to "form.php"?

Thanks for your help!

sidney

with mail function you will have to edit the $to and $from values

<?php   

session_start();
$_POST['formnum']++;
$formnum = $_POST['formnum'];
	if ($formnum > 1)
	{
	echo "submited data<br>";
		foreach($_POST as $key => $value)
		{
			if (!session_is_registered($key)) 
			{
   			session_register($key);
			}
 			else 
			{ 
 			$_SESSION[$key]=$value;
			}
		echo $key." - ".$value."<br>";
		}
	echo"-----------------<br>";
	}
echo"<form action=\"".$PHP_SELF."\" name=\"form$formnum\" method=\"post\">";
echo"<input name=\"formnum\" type=\"hidden\" value=\"$formnum\">"; 
	if ($formnum == 3) 
	{
	$message=""; 
	echo "session data<br>";
	// process data from form 2 
		foreach($_SESSION as $k => $v)
		{
		$message.=$k." - ".$v."<br>"; 
		echo $k." - ".$v."<br>";
		}
	$to="test@hotmail.com";
	$from="hostaccount@domain.co.uk";
	$subject="A message from your form";
	$headers = "From: My Form <$from>\r\n";
	$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
 		if(mail($to,$subject,$message,$headers))
 		{
 		echo"mail sent succesfully";
 		}
 		else
 		{
 		echo"Unable to send mail";
		}
	} 
	elseif ($formnum == 1) 
	{ 
	?> 
	<p> 
	<input name="Name" type="text" id="Name"> 
	</p> 
	<p> 
	<input name="Email" type="text" id="Email"> 
	</p> 
	<p> 
	<input name="Phone" type="text" id="Phone"> 
	</p> 
	<?php 
	} 
	elseif ($formnum == 2) 
	{
	?> 
	<p>  

	<input name="1" type="radio" value="radiobutton"> 
	</p> 
	<p> 
	<input name="2" type="radio" value="radiobutton"> 
	</p> 
	<p> 
	<input name="3" type="radio" value="radiobutton"> 
	</p> 
	<?php 
	} 
	else
	{ 
	echo"error";
	}
?>
<p> 
<input type="submit" name="Submit" value="Submit"> 
</p>
</form>

I get these errors when I click submit on the first form:

Warning: session_start(): Cannot send session cookie - headers already sent by...

Warning: session_start(): Cannot send session cache limiter - headers already sent ...

sidney

sidney

add

<?php
ob_start();?>

to very top

and

<?php
ob_end_flush();
?>

to the very bottom

also

remove this from just below body tag its redundant as form tag
is echoed further down

and

from="$Email";

should be

from=$_SESSION['Email'];

kranzoky

I did all that, but I still get those warnings. It says it is from this line on the page:

session_start();

sidney

make sure ob start is the first thing on page before <html> tag

and ob_end the very last
basicly its buffering the output of the page so headers anrt sent before session starts

you could also move session_start up to top below ob_start

kranzoky

Hmmmmm? I did that and the errors still come up?

sidney

works for me should have sent an email to the addresss in script

 <?php
ob_start();?>
