PHP Redirect?

Copy linkTweet thisAlerts:
Mar 21.2007

How can I redirect to another page in an If statement? Heres what the pseudo-code looks like…

[code=php]
if(condition){
do this
}else{
redirect to another page
}
[/code]

Can this be done?

@JickMar 21.2007 — If I understand you correctly, I believe you're looking for something like this:[code=php]if(condition) {
do this
} else {
header('Location: mypage.php');
exit();
}[/code]It uses the [B][FONT="Courier New"]header[/FONT][/B] function. Please let me know if I misunderstood the question.

@r_soleauthorMar 21.2007 — Does that work if I have something like ...
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

<title>Untitled Document</title>

</head>[/QUOTE]

above it or not?

yes dear , what Jick said works if you have something like what u stated above . and here is another method as well >

you can use this HTML code :

print '<meta http-equiv="refresh" content="2;url=mypage.php">';

it may not work properly unless u use ( ob_start(); ) at the very begining of your script .

@r_soleauthorMar 21.2007 — When the page is redirected will my variable's values be passed over to the new page. Like in this ...

[code=php]
if(something){
do something
}else{
$test = true;
header('Location: page.php');
exit();
[/code]

Would $test be true in page.php?

@m_sahalyMar 21.2007 — yes ofcourse , but this is in case you appended them to the URL and you can appened as many variables as you like in the URL like the following :

header('Location: page.php?var1=value1&var2=value2');

@r_soleauthorMar 21.2007 — Just a question... Why is that forms can easily pass values on to another page but without a form you need to use the querystring.
Copy linkTweet thisAlerts:
@m_sahalyMar 21.2007 — you surly know that evern forms may append there content to the Querystring if its method is GET .the alternatives are as you said Query string , session ,DB ,and files may be .

I donot know if i answered ur Q or not .but feel free to ask .
Copy linkTweet thisAlerts:
@r_soleauthorMar 21.2007 — What I meant was, forms don't use the querystring but still manage to pass on values to other pages. Isn't there some way for me to pass on a certain value without the querystring?

@m_sahalyMar 21.2007 — sessions

@itbeingsMar 21.2007 — [code=php]if(!empty($_SESSION['User']) && $_SESSION['User']['Log.Member'] == "Member.Logged"){
#Allow user to see the member area
}
else{
##
#Your Login page already defined in 'config.inc' if any
define('LogIn', 'http://www.domain.com/LogIn/');
#
##
header("Location: ".LogIn."?_rPath=".$_SERVER['HTTP_REFERER']."?".$_SERVER['QUERY_STRING'].""); //Go to login page and remember the last page view
}


///Now on you login page
//If user is authenticated
##
#Your Member page already defined in 'config.inc' if any
define('MemberArea', 'http://www.domain.com/Members/');
#
##
if(!empty($_SERVER['QUERY_STRING']) || !empty($_GET['_rPath']))
$ReturnPath = $_GET['_rPath'];
else:
$ReturnPath = MemberArea;
endif;
#Forward user to the Return Path
header("Location: ".$ReturnPath."");
[/code]

@r_soleauthorMar 21.2007 — Sweet, sessions work great.
Copy linkTweet thisAlerts:
@r_soleauthorMar 21.2007 — Is it possible to have a link that, when clicked, will change a session value?
Copy linkTweet thisAlerts:
@itbeingsMar 21.2007 — It's possible. All you have to do is to set a value to it as soon as it get to the other page.
[code=php]
//On page A
$_SESSION['A'] = "Me";
echo '<a href="look.php">Check it</a>';


//On look.php
$_SESSION['A'] = "What I like now";
[/code]

Does that help. I mean is that what you are asking?

@r_soleauthorMar 21.2007 — Yeah thats what I was asking. THanks dude.
