[RESOLVED] variable problem help needed

lozza1978

Hi All,

I have a form (form.php)

Now the user can reach this form via 3 ways by clicking the links(link1=UK, link2=Spain, link3=Portugal),

When the user enter the form.php, the $_GET grabs the country code from the url, and this is displayed on the page, Saying "Contact Us -UK/Spain/etc"

the code i have used is just a simple if statement

if($GET['country'] == 'UK') {
$location = 'UK';
}

when required i just echo $location, in the script and this works

The problem I have is the form validates itsself,
(so the form sends the POST info to itself) if the form passes or fails there is no longer a $_GET variable in the URL,

so in the mail function i have wrote $location does NOT output as theres nothing in the URL

I really hope you understand what I am trying to say, I have been working on this form all over the weekend and just hit a big wall,()BANG

Maybe I should not use the GET function, could someone show me a better way?

thanks for reading

This might be a problem with your (x)html code, check to see if you have method="get" written instead of method="post" in your <form> tag.

thanks for your reply damm quick,

at the moment I am trying to POST the country code to reloaded page, 2nd time round,

my plan is
the user comes in to the form on a GET request, which displays the info nicly the first time round, the user fills the form and the info is posted to itseld, this time(2nd time) there is no GET in the URL, doesnt matter the page passed validation,

at the moment im trying to post a hidden field with the if statement to see if this works(code below,)

<input type="hidden" name="location" value="<?
if($GET[country] == 'uk') {
echo 'UK';
}
if ($GET['country'] == 'rotw') {
echo 'Rest of the World';
}
if ($_GET['country'] == 'usa') {
echo 'USA';
}

?>">

so the first time round the GET command will ouput the value to the POST, which 2nd time round will pick up the hidden field and output the correct variable,

I hope this works,

in the mean time if anyone has any easier ideas then please share,

cheers for reading

Hi,

You could set the form method to GET, or, you can use a small function to check the $POST and the $GET array for a variable, or e.g.

if(isset($POST[country]))
{
$country = $POST[country];
}
else
{

if(isset($GET[country]))
{
$country = $GET[country];
}
}

use request instead of get/post
it will check both and use whatevers there... you can set what order in the php.ini

<input type="hidden" name="country" value="<?=$_REQUEST['country'];?>">

So when you come to the page.. it sets the hidden field with the query item 'country'.. when you submit use:

if($_request['country']=='UK') {
$location = 'UK';
}

the hidden field should keep that variable each time you post the page, unless you load the page for the first tiem w/o the variable country in the query string... then you'll get a notice error because the request is unidentified.

Just one thing: Be carefull that the input is what you expect: It is easy for someone to place an SQL statement in the web-address, which could be inserted in your script this way. So use something like addslashes, htmlencode or check the actuial value (Like the if/then statements you showed in the initial post) to prevent this sql-insertion.

Thanks so much for all the help on this, I have run some initial tests and I seem to have a working version of the script,

I need to keep testing, to make sure the script does not break down with a few failed validations or sql injections , I dont think it will, but you have to test specially as im a newbie,

cheers,
problem solved in under an hour, what a forum 🙂 (I hope problem solved)

If this is solved, please mark it so!

BTW, your title is syntactically-incorrect 😃
It should be: <?="help"?>

This will work and save you some trouble of people trying to get around your script.

$location = $_GET['location'];

if ($location == usa){
echo "DISPLAY USA";
} else if ($location == spain){
echo "DISPLAY SPAIN";
} else if ($location == uk){
echo "DISPLAY UK";
} else {
echo "DISPLAY THE FORM HERE";
}
