Keeping Info in a Form

[Ethics]

Hey,

So I have a form where it redirects you to a error page if you missed a field.

The problem with this is, that it clears all the fields that you did type in. So I want it to carry these fields over to the error page, even if some are missing.

Here's some of the code in my form to help you see how I'm doing this...

	$name = $_POST['name'];
	$email = $_POST['email'];
	$sex = $_POST['sex'];
	$security = $_POST['security'];
	$comments = $_POST['comments'];

	if (!empty($errors)) {
		header("Location: feedback_error.php?errors=" . urlencode(implode(", ", $errors)));
		exit;
	}

I know how this can be achieved, but I can't wrap my head around how I might get it to work.

Basically I can check if they entered something other then the default value and pass that through in the url. Then read it back on the error page from the url. I'm just not sure how I could achieve this.

I'm going to go and try to figure it out, but if anyone can help that'd be awesome.

Thanks,
Mario

Hi there, my 1st post here.
About your problem, you can put your html to point to the same page. Here you just check if something was submitted.

<?php
//stuff ...

if( isset($_POST[name]) ){
// check for stuff here
}else{
?>
<!--put html here-->

<form action=""...
<input name="name" value="<?=$_POST['name']?>" />
....etc
<!-- end html :) -->
<?php
}
?>

Please note the value="<?=$_POST['name']?>"

Rather than redirecting on error, why not just submit to the same page then just store into $error. Then you still have all submitted fields that you can put into the form fields' value attribute

[andr]

Yup, triexa is right. You can add an $error variable and then juggle with it
I hope it helps. If you still have trouble tell us.

Thanks for the replies guys.

Thats a good point, I throw in a new div on top when theres an error stating what error happened. I guess I just can't figure out how to keep that on the same page.

Thanks,

I'm basically trying to do this...

1. Check if the name field is not blank or the value within does not equal Name.

2. If it passes the first test, pass the value contained in $name to the url on the error page. So then I could just pull it from there and fill the field in.

Here's the code I'm using but it doesn't seem to be working.

if (!empty($name)) {
		$saved_name = $name;
	}

	if (!empty($errors)) {
		header("Location: feedback_error.php?errors=" . urlencode(implode(", ", $errors))) . "&name=" . urlencode($saved_name);
		exit;
	}

But it's not working. Is it because $name is not a global variable and can't be called from outside of the function?

Thanks,
Mario

before if (!empty($name)) {
put this: $name = $_POST['name'];

[Ethics]

i have all that just above that code...

	$headersep = (!isset($check) || (check == 0))?"\r\n":"\n";
	$name = $_POST['name'];
	$email = $_POST['email'];
	$sex = $_POST['sex'];
	$security = $_POST['security'];
	$comments = $_POST['comments'];
	$http_referer = getenv("HTTP_REFERER");

any other ideas?

Thanks,
Mario

[andr]

also before that you should check if( isset($_POST['name']))

Maybe it'll help if you guys see the form, you can find it here...

[andr]

ooww simultaneous posting...
you can call that function with the parameters $name, $sex, etc. or you can make those vars globals

[Ethics]

name will always be set, cause it has a default value of Name in it.

So i can use...

if (!empty($name) || ($name != Name)) {
		$saved_name = $name;
	}

[triexa]

Well, do you have something like $name = $_POST['name']?


As for "same page" something like:

<?
if ($_POST) {
    if ($_POST['name'] != 'Kaitlyn')
        $error = 'You did not enter a good enough name';
}

if (isset($error)) {
    echo '<div style="color:#FF000; font-weight:bold">' . $error . '</div>';
}
?>
<form action="this_script.php" method="post">
Your name: <input type="text" name="name" value="<?=$_POST['name']?>" />
<input type="submit" value="Submit" />
</form>

Sweet triexa, I'm going to try to use that code right now to cur off the error page.

Thanks

Anyone on the other problem? :-P

[triexa]

name will always be set, cause it has a default value of Name in it.

So i can use...

if (!empty($name) || ($name != Name)) {
		$saved_name = $name;
	}

Name needs to be in quotes..

$name != 'Name'

or

$name != "Name"

Hey,

Thanks for trying guys,

Let me try to make the question super simple to understand cause we've gotten a bit off track.

if (!empty($errors)) {
		header("Location: feedback_error.php?errors=" . urlencode(implode(", ", $errors)));
		exit;
	}

How can I add more to this line, so that more shows up in the browser window.

I tried...

if (!empty($errors)) {
		header("Location: feedback_error.php?errors=" . urlencode(implode(", ", $errors)) . "&name=");
		exit;
	}

But that doesn't add it to the url.

Any ideas?

Thanks,
Mario

[triexa]

I don't understand why you've gone back to the redirect on error, and then try to pass all the data back in the URL...
