Redirect question

[kevin99]

Hello

I was hoping to create a redirect based on the query string. It would only send the user to a different page if the season was in the query string.

if ($season ==("low")
{
$url== ("lowseason.html")
}
else
{
$url == ("ortherseasons.html");
}

I would then add to the bottom of the script.

header("Location: $url");

It doesn't work of course, so I'm hoping you guys can help me out, or if it is even possible.
Hope this makes sense.

Thanks

if ($season == "low") 
{ 
header("Location: lowseason.html");
} 
else 
{ 
header("Location: ortherseasons.html"); 
}

Thanks for your quick reply, but it keeps defaulting to the otherseasons.html, no matter what is selected. Any other suggestions?

if ($_GET['season'] == "low")  

{  

header("Location: lowseason.html"); 
}  

else  

{  

header("Location: ortherseasons.html");  

}

Or you can use

switch ($_GET['season'])  

{  

case low:
header("Location: lowseason.html");
break;
default: 
header("Location: ortherseasons.html"); 
break; 
}

Sorry the first time I replied didn't work, I assumed you had already stripped the "season" variable from the $_GET superglobal 🙂

Many thanks, it's working great. Your help is most appreciated.

But do you understand why your version didn't work?? 🙂

Here's the two reasons...

First:

if ($season ==("low") 

Should have been

if ($season == "low") 

You started a bracket and used the isequal to '==' operator but enclosed the argument 'low' in brackets (and didn't close the other bracket either.)

Also.. your variable..

Came from a query string.. eg..
http://www.somewebsite?season=low

$season

It should have been

$_GET['season']

(Search for threads/posts on "register_globals" for the full reasons why) 🙂

I'm still learning, but getting there, slowly.
How would I write it if I wanted low and mid season to go to lowseason.html?

Again thanks for your help.

It takes time 🙂

The hardest part is understanding why something isn't working and how to get it working (safely) 🙂

So.. to answer your question, there are several ways to what you asked... (and introduce you to "alternative syntax" .. in this case.. the "switch" statement).
Method1 (if/elseif/else):

if ($_GET['season'] == "low")   

{   

header("Location: lowseason.html");  

}   

elseif ($_GET['season'] == "mid") 
{   

header("Location: lowseason.html");  

} 
else
{   

header("Location: ortherseasons.html");   

}

Method2 (if/else)

if ($_GET['season'] == "low" || $_GET['season'] == "mid")   

{   

header("Location: lowseason.html");  

} 
else
{   

header("Location: ortherseasons.html");   

}

Method3 (Switch)

switch ($_GET['season'])   

{   

case low:
case mid: 
header("Location: lowseason.html"); 
break; 
default:  

header("Location: ortherseasons.html");  

break;  

}

These three aren't the exhaustive list of ways to achieve your goal. Which you choose is up to you (as you are just starting out). Id personally go for the Switch but.. that's upto you 🙂

Most important here is to understand WHY it works and how each are useful for different situations 🙂
