Url $_GET

[renfley]

K hey guys hoping one of you can help me out lol,

 

Problem=

When someone clicks a link it directs them to index.php?page=home

<ul>

      <li><a href="index.php?page=home">Home</a></li>

      <li><a href="index.php?page=about">About us</a></li>

      <li><a href="index.php?page=contact">Contact us</a></li>

</ul>

 

What im trying to achieve is since it the same page i wanna display different content based on the page= ?

 

i was wondering if someone could write something quick basicly

 

<?php

          (verify to see if there is something after index.php ex: ?page=home)

        if there isnt

            echo 'welcome to my site';

        and if there is somethign there

          echo 'include/page/contact.php';

?>

 

Srry if this sound messed up lol

[Deoctor]

u can actually do one thing change that to index_new.php

and then in the index_new.php

u can write something like this

<?php
include("index.php");
?>

 

so what it will do is that when ever some one cliks on the link it will send the request to index_new.php file and that in turn pass the values back to the index.php

 

so in the top of index page u can write something like this

 

$Page=$_GET['page'];

[nilansanjaya]

use something like this

"varname" is the part u have after "index.php?"

 

if(isset($_GET['var_name'])){

//do what you want if there's something after "?"

}else{

//if not...then here...

}

actually you shouldnt really do that because then the user could set the url as http://www.example.com/index.php?page=phpfreaksisawesome and it wouldnt load the index even tho thats not a real page

 

Try:

<?php

$page = $_REQUEST['page'];

if ($page == "contact")
{
require('contact page');
}
else if ($page == "about")
{
require('about page');
}
else if (($page == "home") || (!$page))
{
// your code for the home page
}

?>

}

?>

 

yeah...good point !

Its better to use a switch statement tho

<?php

switch($_GET['page']){
case 'home':
// include or whatever on home
break;
case 'news':
// include or whatever on news
break;
default:
// include or whatever when $_GET['page'] doesnt match other case, or dont exist
}

?>

ALPINE You got the ball lol

 

so ive changed this

 

<?php

 

$page = $_REQUEST['page'];

 

if ($page == "home")

{

include ('pages/home.php');

}

else if ($page == "products")

{

include ('pages/products.php');

}

else if ($page == "about")

{

include ('pages/about.php');

}

else if ($page == "order")

{

include ('pages/order.php');

}

else if ($page == "contact")

{

include ('pages/contact.php');

}

else if (($page == "home") || (!$page))

{

// your code for the home page

echo 'welcome home';

}

else

{

echo 'hello';

}

 

 

?>

 

The next issue is that because when the page loads its only index.php and not (index.php?page=home)

It give me

Notice: Undefined index: page in C:\wamp\www\Store Front\index.php on line 66

welcome home

 

Any suggestions

[Deoctor]

u can try my suggestion..

[renfley]

i think it would work if i could

<?php

 

include ('index.php?page=home');

 

?>

 

But i cant

[renfley]

If you are wondering found a quick solution that will save on code space lol

 

<?php

$page = $_GET['page'];

if ($page)

{

include ("include/".$page.".php");

}

else

{

echo 'Welcome to home page';

}

?>

 

Only problem is the original

Notice: Undefined index: page in C:\wamp\www\Store Front\index.php on line 66

Welcome to home page

[nilansanjaya]

use isset() to check weather that variable is set or not

[renfley]

You mean :

 

<?php

  $page = (isset($page))

  if ($page)

  {

      include ("include/".$page.".php");

  }

 

 

????

[nilansanjaya]

easy to do like this

 

<?php
   if (isset($_GET['page']))
   {
      include ("include/".$_GET['page'].".php");
   }
   else
   {
      echo 'Welcome to home page';
   }
   ?>

Alpines solution is currently the most widely-used and elegant way of doing what you're trying to achieve.

[Tazerenix]

yea, there is just something about switches i dislike for some reason lol.

 

And in your code set page to if (isset($_GET['page']) $page = $_GET['page'];
