Any Smarty way to check we are in front page of a site?

Hi!

SOmetime ago I hacked a site to generate a Smarty variable when we were in front page. Now I'd like to do the same thing but without HACKING THE CORE.

Is there a Smarty variable or set of IFs I can use to evaluate we are in front page?

Thank you.

I am not sure myself but maybe your answer is here.

If you solve this question could you post the answer?

Hi,

With no hack on core files i don't know, but in my sites i made something like this:

in header.php
Quote:

if ($_SERVER['PHP_SELF'] == '/index.php'){
$xoopsTpl->assign( 'isIndex', true );
}else{
$xoopsTpl->assign( 'isIndex', false );
}


in theme.html
Quote:

<{if $isIndex}>
.... some code here .....
<{/if}>


If anyone have a best way to do this, please let us know.

Regards

I've done something very similar to rplima2004 but I just added it all to the theme...

Towards the top of the theme add the following:
<{php}>
$myurl = strtolower($_SERVER['PHP_SELF']);
if ($myurl == (DIRECTORY_SEPARATOR.'index.php')) {
  $this->assign(var='ishome' value=true);
}else{
  $this->assign(var='ishome' value=false);
}
<{/php}>


And then when you want to use the code later in the theme you can just do something like:
<{if $ishome}>
  We are on the home page
<{else}>
  We are NOT on the home page
<{/if}>


Of course you could put the php code listed above in a Smarty include if you'd like...
EDIT: Modified the code above slightly to allow it to work on either a windows or *nix server...

I've used the same method as kaotik with good results - much simpler, too.

skenow / kaotik,

I think the code you have listed will give a false positive for any file you execute in the root directory. So for example if you try this on /user.php it will test true even though you're not on /index.php.

Sorry but I'm not sure these methods are "all terrain, any weather".

Using PHP_SELF does not consider the script receiving variables, so it would give a false positive in News module when browsing latest news in a category.

XOOPS core itself also has this problem, see this bug:

http://sourceforge.net/tracker/index.php?func=detail&aid=1811479&group_id=41586&atid=430840

The other method, detecting the system module... is it supposed to work when the start module is any other module?

Drupal has a global variable named $is_front. I think we should copy that.

Although the problem is fixed for me, I'd check the bug report above and add a line after the IF statement, like this:

define ("IS_FRONT", true);

So we can check it in the theme, like this:

{$smarty.const.IS_FRONT}

Okay... So I thought about it a little more and here's some code that will work - most of the time. Just place this code at the top of your theme (or include it) and then you can reference the <{$ishome}> smarty variable to figure out if you're on the home page.

<{php}>
global $xoopsConfig;
$xbase = basename(XOOPS_URL);
$myloc = $_SERVER['PHP_SELF'];

$xdir = strtolower(DIRECTORY_SEPARATOR . $xbase);
if ($xdir != DIRECTORY_SEPARATOR) {
  $pattern = "'/".$xbase."/'";
  $myloc = preg_replace($pattern,'',$myloc);
}
$startloc= (!empty($xoopsConfig ['startpage'])) ? 'modules'.DIRECTORY_SEPARATOR.$xoopsConfig['startpage'].DIRECTORY_SEPARATOR.'index.php' : 'index.php' ;
if ( ($myloc == $startloc) && (empty($_SERVER['argv'])) ) {
 $this->assign('ishome',true);
}else{
  $this->assign('ishome',false);
}
<{/php}>


The code at the beginning, while strange, checks to see if XOOPS is installed in a subdirectory off the site's root. So this will work even if XOOPS is installed inhttp://yoursite.com/xoops instead of inhttp://yoursite.com

There's an instance where if you post variables to the module's index page then it will still tell you it's a home page, even though technically it's not the "home" page. The code in the bug report that nachenko referenced above suffers from the same limitation.

EDIT:Fixed DIRECTORY_SEPARATOR for both WIN and *nix - again
