Hey guys,

I have downloaded http://simplehtmldom.sourceforge.net/ library into my wp-content. Now I want to include this file into my function in functions.php.

But I dont know what kind of URL I should use here. Please, can you give me an advice? The code:
```
function foobar_func( $atts ){
require_once('URL path?/simple_html_dom.php');
$html = file_get_html('http://hokejbal.cz/1-liga/tabulky/');
$ret = $html->find('table.standings', 1);
print $ret;
```

a “require” statement uses a file path, not a URL.

ok, so it would be the FTP path?

It would be a relative path to the location of functions.php.

Hi ragulin,

The quickest way to do an include of that library is thru your theme’s function.php, some suggested steps to do that:
1) Copy the files http://simplehtmldom.sourceforge.net/ inside your theme’s folder eg simplehtmldom
2) Inside your theme’s function.php file, you can use this modified code to include that 3rd party library
```
function foobar_func( $atts ){
require_once('simplehtmldom/simple_html_dom.php');
$html = file_get_html('http://hokejbal.cz/1-liga/tabulky/');
$ret = $html->find('table.standings', 1);
print $ret;
}
```
3) You can now call the foobar_func in any of your template files.

The best way to do this is creating a plugin (Google for it) so your custom code won’t be lost when you switch themes.

Okay, my code in functions.php
```
function foobar_func( $atts ){
	require_once('ftp://skkelticz@ftpx.forpsi.com/www/wp-content/themes/sporty-child/simple_html_dom.php');
	$html = file_get_html('http://hokejbal.cz/1-liga/tabulky/');
	$ret = $html->find('table.standings', 1);
	print $ret;
	
}
add_shortcode( 'foobar', 'foobar_func' );
```
And errors I get when I try to call the function via shortcode in my page
```

Most servers (including yours) disable the ability to use URL wrappers (ftp://, http://, etc) in the include() and require() statements.

I’d suggest putting your “simplehtmldom” directory in the WordPress root, where wp-config.php is located. You can then include your file in WordPress with the following line:

require_once(ABSPATH . 'simplehtmldom/simple_html_dom.php');
