PHP Reg. form -Pass user input to html form field

[birdman]

I'm stuck trying to have PhP script post to next form. My script, addUser.php, checks flat DB file, users.php, against user input and returns if name is already taken. If not available it returns user to addUser.php, if available it sends user to reg.htm requiring user to complete registration.

The forms input text field, "user" is named in the addUser.php which is to post or pass the users input into the reg.htm forms "user" input box.

Everthing works fine except posting the avilable name user creates to the next forms "user" text field.

Have been struggling with this due to inexperience of PhP know -how.
Any help will be gratly appreciated..... this is my first php attempt.

Thanks in Advance,

PHP won't be parsed on a page with a .htm or .html extension. You need to change it to reg.php, and change your original form to post to that instead, and that should work for you...

Also, change this:

<input type="text" name="user" value="?php echo $_POST['user'];?"> 

to this:

<input type="text" name="user" value="<?php echo $_POST['user'];?>"> 

Other than that, the code looks fine.

TheDefender,

Hey, thanks for responding to my sos.
I made the 2 corections you metioned,
but is still not posting data into the reg.php form.

It does, however, no longer have the PHP
code within the reg.php "user" field.

Might there be something else I missed or are completely unaware of?

Thanks in Advance,

[TheDefender]

I do have some concerns with the code you are using on the addUser.php page, such as why you have 3 different inputs all named user?

And on your reg.php page, add this line:

print_r($_POST);

So you can see what's actually in the post array. It sounds like your POST array is empty (or at the very least, like the 'user' index isn't defined.)

[birdman]

This is how mu addUser.php code looks now:

<?php
session_start();	
header("Cache-control: private");

if(@$_SESSION['user']) header("location: login.php");
elseif(@$_POST['user']){
	$user = htmlspecialchars(strtolower($_POST["user"]));
	$string = "\r\n". $user. "<del>". 

$file = file("users.php") or die("Problem getting the user details flat-file [users.php]");

$totalLines = sizeof($file);

$line = 0;
$match = 0;
do{
	if("//" != substr($file[$line], 0, 2)){
		@list($USER) = explode("<del>", $file[$line]);

		if((strtolower($user) == strtolower($USER))) $match = 1;
		else $match = 0;
	}

	if($match) break;

	$line++;
} while($line < $totalLines);

if($match){

?>
	<script language = "javascript" type = "text/javascript">
	<!-- // Go back
		alert("NAME already taken, taking you back to choose another");
		history.go(-1);
	-->
	</script>
<?php
}
else{

  $fp = fopen("users.php", "a");

  fwrite($fp, $string);

  fclose($fp);

  header("location: ../reg.php#dwn");

    echo "<input type=\"text\" name=\"user\" value=\"<".$_POST['user']."\">";
}
}
else{
?>

<form NAME="form1" method = "post" action = "<?php echo $_SERVER['PHP_SELF']; ?>">

<input name="user" type="text" class="text" id="user">

I deleted the hidden input for the "user" field on the addUser.php form.

I replaced it with the value"" of the "user" input on reg.php, but only receive Array() when testing.
May I ask were should the following code be placed in the reg.php page?

<input type="text" name="user" value="<?php print_r($_POST);?>">

Thanks, hope U don't get frustrated with a scattered brain newbie like me.

[TheDefender]

Right at the top...

<?php
print_r($_POST);
?>

And by the way, I have all of the patience in the world... Just want to do my part to help you get your code working.

[birdman]

Ok, thanks..... I'll post it at the top and put the previous input code back in the "user" field.

[birdman]

Ok, the code has been pasted above the <htm> of the reg.php page. On testing the Array() just appears.... everything else still works.

?? yep, I be lost.

[TheDefender]

OK, if all you see is Array(), then that means the array is empty, so you need to go back and figure out why the values aren't being posted properly.

Now that I look back at your adduser.php page, I see you are posting the page to itself, so how/where are you posting to the reg.php?

[birdman]

Within the addUser.php form, the action post to itself in order to
first check the users.php for available user name.

The following code is suppose to refer to posting the available user
name within the "user" input field when the user is taken to reg.php.

<?php
}
else{

  $fp = fopen("users.php", "a");

  fwrite($fp, $string);

  fclose($fp);

  header("location: ../reg.php#dwn");

    echo "<input type=\"text\" name=\"user\" value=\"<".$_POST['user']."\">";
}
}
else{
?>

Now I see that this is where the real problem is, but how do tell the script to post to reg.php correctly after an avilable user name is selected?

[TheDefender]

You can't post a variable using the header() function...

[birdman]

I know this now.... I first tried it with 'isset' but due to my newness to php
I screwed that up too. This is the code I originally attempted but had
to many unexpected $ Parse errors.

Then of course nothing worked.

	<?php 

  if(!isset($_POST['submit'])){

  //show application form
}

else{

  $fp = fopen("users.php", "a");

  fwrite($fp, $string);

  fclose($fp);

  if($existcheckvariable){

  }
  else{

  header("location: ../reg.htm#dwn");

    echo "<input type=\"text\" name=\"user\" value=\"".$_POST['user']."\">";
  }

}
?>

How would you suggest I do this to make it workable, or what PHP lesson need I return to?
