Post Form DATA to another page after PHP Validation
Question
I have this issue with my validation and posting the data to another page.
Here is my form:
Signup.php
<form id="regForm" action="<?php echo htmlspecialchars($_SERVER["submit.php"]);?>" method="post" name="regForm">
<label for="fname">First Name:</label><input name="fname" type="text" size="25" maxlength="35" value="<?php if(isset($_POST['fname'])){echo $_POST['fname'];}?>"/><br/>
<label for="mdname">Middle initial:</label><input name="mdname" type="text" size="10" maxlength="35" value="<?php if(isset($_POST['mdname'])){echo $_POST['mdname'];}?>"/><br/>
<label for="lname">Last Name:</label><input name="lname" type="text" size="25" maxlength="35" value="<?php if(isset($_POST['lname'])){echo $_POST['lname'];}?>"/><br/>
<br/>
<label> </label><input type="submit" name="Signup" class="formButton" value="Signup" /></form>
And here is my submit.php which will validate the signup.html input
submit.php
function msg($status,$txt)
{
return '{"status":'.$status.',"txt":"'.$txt.'"}';
}
// we check if everything is filled in and perform checks
//check if fname is empty
if(!$_POST['fname'])
{
die(msg(0,"<p>Please enter your first name.</p>"));
}
//check if lname is empty
if(!$_POST['lname'])
{
die(msg(0,"<p>Please enter your last name.</p>"));
}
Now, my issue is this, in my "submit.php" file, I want to know what codes to put after the form fields validation that would enable me post the input data to another page because, I plan making it a two-page signup form. Let's say my next page is signup-2.html
how do I post the data after validation to the next page? I know how to retrieve the posted data on the next page like using Session or Echo the $_POST data but, my main issue is....how do I make the form post the data after the validation messages in my submit.php file?

use header :
header("Location: your page url?fname=$_POST['fname']&lname=$_POST['lname']");
but before this do not echo or print anything otherwise it won't redirect to that page.
you can use the data on destination page like this:
$_GET['fname']
example:
submit.php
function msg($status,$txt)
{
return '{"status":'.$status.',"txt":"'.$txt.'"}';
}
// we check if everything is filled in and perform checks
//check if fname is empty
if(!$_POST['fname'])
{
die(msg(0,"<p>Please enter your first name.</p>"));
}
//check if lname is empty
if(!$_POST['lname'])
{
die(msg(0,"<p>Please enter your last name.</p>"));
}
header('Location:download.php?fname='.$_POST['fname']."&lname=".$_POST['lname']);
view.php
<html>
<body>
<form action="submit.php" method="post">
<input type='text' id="fname" name="fname"/>
<input type='text' id="lname" name="lname"/>
<input type="submit" id="button" value="submit"/>
</form>
</body>
</html>
download.php
<?php
echo "First Name........".$_GET['fname'];
put these three file in same directory and run view.php. you will be ok.
