Hi friends,
I have a multi form(actually is one whole form, but split into multiple forms).
From the image seen
When i typed the name data in Form 1, and click the next button and go to Form 2...
In Form 2 when i typed the Email data..and then i realize, the name data that i entered in Form 1, is wrong, so, I click the <Back button in Form 2..and i go in but i dont see the data that i typed in, then when i click the next button in Form1 to go to Form 2> I cant see the data thats been typed in Form 2 also..
I can insert the data into table, If i just go forward.... >>
ie:
Form1 -> Form 2 -> Result.
How can this problem be solved?
I want to see the data's that been typed in, either if they go <back or Forward>..
Can some1 guide me with this..

Thanks,
Tryphy

Could you not use a $_SESSION and pass a session to each page? once the form is complete you can kill the session.

Might not be the best solution

Hope it helps...

you can make it in a simpler way if you are having only one field.
Form1.php

<?php
$formdata = "<form name='form1' action='form2.php' method='post' >";
$formdata .= "<input type='hidden' name='email' value='".$email."' />";
$formdata .= "<input type='text' name='username' value='".$username."' />";
$formdata .= "<br /><br />";
$formdata .= "<input type='submit' name='next' value='Next' />";
$formdata .= "</form>";
?>

Form2.php

<?php
$email = $_POST['email'];
$username =  $_POST['username'];
$formdata = "<form name='form2' action='form3.php' method='post' >";
$formdata .= "<input type='hidden' name='username' value='".$username."' />";
$formdata .= "<input type='text' name='email' value='".$email."' />";
$formdata .= "<br /><br />";
$formdata .= "<input type='button' name='back' value='Back' />";
$formdata .= "<input type='submit' name='next' value='Next' />";
$formdata .= "</form>";
?>

I assume you do know how to post the values to form1.php when you push the 'Back' button in form2.php
Also note that in form1.php 'email' field is hidden and in form2.php 'username' field is hidden.

Hope the above code snippet helps.

forgive me for sounding really dense but wouldn't you just use

<input type="text" name="txt_phone" id="txt_phone" value=" <?php echo $n;?>" />

or use a

if (isset($n){echo "value=\"$n\"";}

hope it helps...
