I've been having this issue for a while but keep just working around it an thought I'd finally get it solved.
I'm trying to include files into my main plugin document (the one that has the plugin title and version in it) like this:
define('SBT_PLUGIN_URL', plugin_dir_url(__FILE__));
include(SBT_PLUGIN_URL . 'competition_table.php');
inside the competition_table.php is an add_shortcode(); function that needs to run, in order for the shortcode to be registered with wordpress:
function add_table() {
//Run code here
}
add_shortcode('competition_table', 'add_table');
When I run the code on the site the link resolves properly, including the correct file, however I get this Fatal Error:
Call to undefined function add_shortcode()
However if I add exactly the same code that is in the competition_table.php into my main plugin document then the code runs perfectly.
So basically, my question is, why is Wordpress not recognizing it's own function and how can I include the file to make the code run properly?
Thanks in advance
You have to develop with WP_DEBUG enabled. It dumps an error: wrapper is disabled in the server configuration. That lead me to this: "Trust me, you do not want to include from URLs.".
Then I realized you're defining that constant with plugin_dir_url(), when what you need is a path. The following magic constant does the job:
include_once __DIR__ . '/competition_table.php';
Thanks to the feedback from #b__ I have managed to solve this issue.
For some reason, Magic Constants don't always work with wordpress, however, you can use it's equivalent to get the same effect:
include_once dirname(__FILE__) . '/competition_table.php';
When including files for use in a wordpress plugin you should always include via a PATH, not by a URL.

I am using WP for the first time. I'm just trying to create a very basic script to echo the user's id and am having all sorts of issues.
The code is this and is currently located in wp-content/plugins (i'm not really sure where these things should be):
<?php
require_once ABSPATH . '/wp-includes/pluggable.php';
$user = wp_get_current_user();
echo $user->get_site_id();
I'd had it without the require initially but I was getting a function not defined error for wp_get_current_user. Now I'm getting Warning: Use of undefined constant ABSPATH - assumed 'ABSPATH'...
Is there some sort of predefined set of files that I need to include or some specific directory I need to be putting my scripts so that these variables and functions are in scope? My understanding was that these things are supposed to be global.
Did you try code like that:
add_action('init', 'some_function_name');
function some_function_name() {
$user = wp_get_current_user();
echo $user->get_site_id();
}
The WordPress comes with hooks (actions and filters) to let other developers modify either core parts of the WordPress or code from other plugins / themes.
The code I describe in my answer, it is running your code when the whole WordPress , all the Plugins and the theme are loaded, thus you should have by default the wp_get_current_user() function and you should not need to include manually the pluggable.php.
This seems like is going to solve your problem.
Read more on hooks here: https://developer.wordpress.org/plugins/hooks/.
Side note. Keep in mind that in order to run your custom code you should register a proper WordPress plugin and activate it. If you have made a php file in the plugins folder, and you loaded using PHP functions like require/include the plugin probably will not operate as you expect although the source code it could be perfect. To get more details on how to write your own plugin, you could read here: https://developer.wordpress.org/plugins/
In my web page, I wrote:
<?php
//define('__PUBLIC__', $_SERVER['DOCUMENT_ROOT'].'/public');
$doc_public = $_SERVER['DOCUMENT_ROOT'].'/public';
echo "Before include...<==============>$doc_public";
?>
<?php require_once($doc_public.'/inc/head.php'); ?>
<?php echo "After include...<==============>$doc_public"; ?>
And the page shows:
This firstly happened when I notice the fatal error in the footer, but the head is fine.
Although I can implement define or constant variable to avoid this, I am still curious how it happens.
P.S.: I run this under Apache with a port 8001. This is set in 【apache\conf\extra\httpd-vhosts.conf】. I am running more than one webapp under this site. I just share this information, as I am not sure this has anything to do with this case.
Thanks!
When you require a file, if a variable is modified it affects the original script as well, that's how it's designed. Require doesn't create a secondary environment separated from the including file, it just adds the PHP code in sequence, exactly like if you had written the code in the initial file.
Have a look at the official PHP documentation, the first example is exactly the same as your case
http://php.net/manual/en/function.include.php
(include is the same as require, the latter just throws an error. For more info about differences between include and require http://php.net/manual/en/function.require.php)
I am getting a strange 500 Internal Server Error with a new script I am trying to implement in the actual site. Here's a screen:
![500 Internal][1]
I can route to this files manually without problems and they are working too. But not in the script itself. The Paths are also correct.
Heres the link to the Site:
[>>> Link <<<][2] (just enter R10369 in the input field or a random number)
Everything else is working correctly except these 3 files:
reseller.php,
checkresellerid.php,
resellermail.php
I googled a bit and everywhere is the .htaccess mentioned. but I never modified it or overwrited it. What could be the Problem? Thanks for any Help and sorry for my bad Englisch.
(Let me know if you want to see the php files)
EDIT: I managed to include my new php files into wordpress but i still got the 500 Error
I checked out the website.
I think Wordpress doesn't let you call .php inside of it's system.
I mean you cannot call PHP files for ajax.
You need to use wordpress ajax. Here is a snippet how to use ajax:
Function.php in your theme file.
function myajax()
{
//do stuff
die();
}
add_action( 'wp_ajax_nopriv_product_s', 'myajax' );
add_action( 'wp_ajax_product_s', 'myajax' );
And in your javascript file using jQuery:
The url may change, maybe it's enough to have wp-admin/admin.ajax.php or something like this, i don't really remember right now.
$.post('/wp-admin/admin-ajax.php',{action:'myajax',yourdata:"mydata"}).done(function(data)
{
//do stuffs
});
Update:
So basically if you want to have ajax request inside wordpresss, you need to define these things and use it like this. the "action" parameter is the function name which you want to call. And you need to put the PHP code into your current theme's function.php.
My other question about getting help with the programming side of wordpress was labeled off topic for some reason so I'm asking a different way. I'm trying to embed my wordpress posts. I'm using this tutorial:
http://www.corvidworks.com/articles/wordpress-content-on-other-pages
The problem is with this code:
<?php
// Include WordPress
define('WP_USE_THEMES', false);
require('./wordpress/wp-load.php');
query_posts('showposts=1');
?>`
When I try to run the page that this is inserted into, I get the error saying that file doesn't exist. Pretending my domain is blah.com, the file is in www.blah.com/wordpress/wp-load.php and the page that includes this PHP code is in www.blah.com/other/page.php.
How do I change the syntax of the link on the require line to make sure it's pointing to the right place since right now it doesn't seem to be working?
have you tried with
require('../wordpress/wp-load.php');
or anyway something like
require('../../wordpress/wp-load.php');
?
(depending on the depth of your file position)
Just like the above answer
This worked for me
require('../wordpress/wp-load.php');
I have my Wordpress blog on blog.mysite.com, and a totally different site (built in my framework) at www.mysite.com.
I know if the blog and another site are on the same server, and have correct permissions, I can use the following to "syndicate" my blogs to the non-blog site with:
define('WP_USE_THEMES', false);
require('/var/www/vhosts/mysite/subdomains/blog/httpdocs/wp-config.php');
query_posts('showposts=5');
...and then run a loop on the page.
The problem is that since my non-blog site is a framework, everything except for my front controller lives in a function - and this is creating the following error for me:
Fatal error: Call to undefined method
stdClass::set_prefix()
(btw, I'm fairly certain the fact that this code is called within a function that is causing the error...when I put the code on the front controller (not in function), the error disappears)
I would REALLY like to have recent blog listings on my non-blog site to spruce it up. Any ideas on how to do this?
Well I guess you forgot to write
global $wpdb
inside the function
