Fatal error: Call to undefined function is_home()

[bloggerz]

hi looking for some help here!

I'm using this code to display something on the home page only, not on the category, posts, or archives pages.

This is the code:

<?php if(is_home() && $post==$posts[0] && !is_paged()) { ?>
ADVERTISEMENT HERE

<?php } ?>

But when I use that I get this error:

Fatal error: Call to undefined function is_home()


Any help is much appreciated thanks!

yes, you're using a function "is_home()" and "is_page()" in an equasion. I don't think you can do that.

Of course you can, the condition statement expects those functions to return a boolean.

The problem you have is that the functions are not defined. (You need to have the functions included in the php file).

You have the code? Pls copy andpaste thx

[HarryMuff]

Why would I have your code?

is it near the top of the page? maybe you're using it before the functions are called in

<?php if (is_home() || !is_archive() || !is_paged() || !is_category() || !is_tag() || !is_single()) {?>

is_home() isn't a native php function. It couldn't ever be, and i'm not even going to begin to explain why.

However, At some point, it's probably been written in some script you previously had.

Are you defining this function elsewhere in your codebase? If so, you'll need to use include() to pull the file that defines the function into the script you're working with. It's kinda like writing something like:

<? fucking(); ?>

This will not work on it's own, but if you have your fucking() function defined in a file like includes/func.fucking.php:

<? function fucking() { echo "do the bartman"; } ?>

Then you'll be able to use that function.:

<? include('includes/func.fucking.php'); fucking(); ?>

and then your code would work. But to save on execution time (opening multiple files takes longer), you could do:

<?  function fucking() { echo "do the bartman"; } fucking(); ?>

PHP Code:

<?php
$homepage = "/";
$currentpage = $_SERVER['REQUEST_URI'];
if($homepage==$currentpage) {
echo 'Adcode here' ;
}
?>

Why create unnecessary variables - when less can do it?

<?php
if($_SERVER['REQUEST_URI'] == '/') {
 echo 'Adcode here';
}
?>

where are you using the code?

i added it to a current theme, and it worked like a charm.

It looks like he wants AND statements, not OR statements?

What I don't get is why you need all the other statements. If it is the home page, then when or why would archive, paged, category, tag, or single ever return? Seems odd to me (though I don't use wordpress a lot).

[potter]

Now that I think about it, wouldn't

<?php if (is_home() || !is_archive() || !is_paged() || !is_category() || !is_tag() || !is_single()) {?>

ad here.

<?php } ?>

Return the ad on a lot more pages than the home page? You're code is basically saying...

[b]Show the ad if:
• It's the home page
• Or if it's not the archive
• Or if it's not paged
• Or if it's not a category
• Or if it's not a tag
• Or if it's not a single.[b]

So it would display the ad on any page that wasn't the archive for instance. Because with all the "OR" double pipes, only one of those circumstances needs to be true for the ad to display.

[b]Show the ad if:
? It's the home page
? Or if it's not the archive
? Or if it's not paged

? Or if it's not a single.[b]

it will only show on the front page.

using that code if i view a category or tag page or full post, it doesnt show the ad.

only on the home, not any paged page2,page3, etc.

Well, it's not-category, and not-paged. My point was

Why not simply use:

<?php if (is_home()) {?>

ad here.

<?php } ?>

??

Because using

<?php if (is_home() || !is_archive() || !is_paged() || !is_category() || !is_tag() || !is_single()) {?>

ad here.

<?php } ?>

Is exactly the same as putting:

<?php if (is_home()) {?>

ad here.

<?php } ?>

and

<?php if (!is_archive()) {?>

ad here.

<?php } ?>

On the same page. So not only will it show up on the home page, but it would want to be shown on any page that ISN'T an archive page.

Maybe I'm not explaining myself, but I just don't understand the point of having alllll those extra OR statements?

ya you would still need to have !is_paged() though, cause home is considered page2 page3 of the index

weird... I suppose it'll all make sense if I ever use wordpress again and see the code and the way the system functions.
