Simple parse url problem

vinny199

Hi i know this is quite simple, but i'm stuck finding the right syntax for it.

I am building a registration form.
I have added a "check username" against existing username in the datatbase fucntion.

so far so good, when the username is already taken, i am sending the user to a new page that says "username already taken, please try new one, and the form is there to fill in again.

Only problem:

How do I make that the values that the user has entered for all the other fileds are parsed to that new page and filled in the form again?
so the user does not have to fill in the form twice.

My redirect page is called: UserRegalreadyexist.php

I know I should make it something like:

UserRegalreadyexist.php?$name="form value",surname="form value" etc.

and then retrieve these values on the form on my page.

but how exactly?

Can you help pls?

Thanks,

Vinny

Simply include with validator in the page...
And then just add value=$_POST[variable] to each field you want to fill...

Make something like:

include("validator.php");
//You should have on your validator.php something like:
If ($_POST){.........}

//Your form.php starts...
<?=$errormsg?>

<form ................................. action=<?=$PHP_SELF?>>
<input type=text name=name value=<?=$_POST[name]?>>
........
</form>

This way your validator only runs when the form is submited and all the fields are filled with the users vars
The $errormsg is one var returned by your validator.php with the error message...
There are other ways, this is just one of them

Cheers

I understand what you are saying, but for various reasons it is just easier if a usename is already found to be in the database the user be redirected to a new page and asked to fill in the form again.

Now, using the principle i mentioned before, of parsing all entered form values from the initial page via url and retieving them on the other page to place them in the form again so most values are "rentered automatically on the form", what would you do?

how would you formulate this pls.
I'm not looking for an alternative way of doing it, but this way.

Can you help?

Many thanks,

Vinny

Well, if you REALLY want to pass those vars in a URL, you should do:

<a href=yoururl.php?name="<?=$name?>"&mail="<?=$mail?>".......

And so one, separating each var with the ampersand (&).
To retrieve the vars from the URL just use:

$name = $_GET['name']
........
........

You have other ways of passing vars, if you dont like this one either send me a tell...

Ah! this is exactly what i need to know, thanks.

It does not quite yet work because of this:

It gets confused with all the " " " " signs as i have to enter the redirect url in this code:

$FF_dupKeyRedirect="UserRegalreadyexist.php";

But replcing UserRegalreadyexist.php with UserRegalreadyexist.php?name="<?=$name?>"&email="<?=$mail?>"&surname="<?=$surname?>"&UPassword="<?=$UPassword?>"&UAccessLevel="<?=$UAccessLevel?>"

messes up the code because of multile " " "

Could it be written differently to fit this format?

Many thatns once again

Just escape the double quotes with () backslash and all should go well...

Edit: or you can simply do:

$yourvar="pagename.php?name".$name."&email=".$email....

and so on...

Boy, I sure do hope you aren't passing a password in the URL as part of this registration script.......................

You should consider using the POST method of sending the form data, and follow the path hmemnon was starting to lead you down... I wouldn't feel very secure if I visited your site, signed up and saw my info (password, name, etc... being passed through the URL) But that's just me I guess.

Also, get out of the lazy habit of using PHP short tags. <?=$name; ?> now before it's too late.
You should always use long tags to ensure code portability:
<?php echo $name; ?>

hmemnon

You're totally right about the <? echo ?> Defender...
I just use the <?= because every single day at work, some intranet needs something new and Im so totally overwhelmed with things that i "sometimes" overlook the long, but most correct way of doing things :p .
hehehehe

Cheers mate

I know what you mean about being overwhelmed and not feeling like you have the time to do it, but consider this... It's an old saying a boss told me 15 years ago, and it has stuck with me since:

"If you don't have time to do it right the first time, when are you going to have time to go back and redo it right later?"
