The short story, I'm getting php to prove to me that the file exists and is readable but the script simply seems to stop running once the include statement is hit.
Also you'll note from the data output further down in this question that I'm using an absolute path.
Some notable things that I've tried in resolving this issue is to:
- replace include with require and require_once
- replace the $include var with a hardcoded string
- replace the hardcoded string to an invalid location using require.
In each of these cases the same thing happens, no script is executed beyond the include or require statement and no errors are thrown.
I'm working on a Woocommerce (which is probably a side and irrelevant point, but possibly helpful) system and it appears to be behaving rather oddly. My code is as follows, I've inserted a pile of var_dumps to demonstrate my issue:
/**
* Output the cart shortcode.
*/
public static function output() {
var_dump("Hello");
// Constants
if ( ! defined( 'WOOCOMMERCE_CART' ) ) {
define( 'WOOCOMMERCE_CART', true );
}
var_dump("After Constants");
// Update Shipping
if ( ! empty( $_POST['calc_shipping'] ) && wp_verify_nonce( $_POST['_wpnonce'], 'woocommerce-cart' ) ) {
self::calculate_shipping();
}
var_dump("After Shipping Calc");
// Check cart items are valid
do_action( 'woocommerce_check_cart_items' );
var_dump("After cart items check");
// Calc totals
WC()->cart->calculate_totals();
var_dump("After Calc Totals");
var_dump(WC()->cart->get_cart());
var_dump(sizeof( WC()->cart->get_cart() ));
if ( 0 === sizeof( WC()->cart->get_cart() ) ) {
var_dump("Size = 0 , Empty");
wc_get_template( 'cart/cart-empty.php' );
} else {
var_dump("Size != 0 , Not Empty");
wc_get_template( 'cart/cart.php' );
}
}
Called wc_get_template() Function:
/**
* Get other templates (e.g. product attributes) passing attributes and including the file.
*
* @access public
* @param string $template_name
* @param array $args (default: array())
* @param string $template_path (default: '')
* @param string $default_path (default: '')
* @return void
*/
function wc_get_template( $template_name, $args = array(), $template_path = '', $default_path = '' ) {
var_dump("wc_get_template fired. Template name = " . $template_name);
if ( $args && is_array( $args ) ) {
extract( $args );
}
$located = wc_locate_template( $template_name, $template_path, $default_path );
var_dump($located);
if ( ! file_exists( $located ) ) {
_doing_it_wrong( __FUNCTION__, sprintf( '<code>%s</code> does not exist.', $located ), '2.1' );
return;
}
var_dump(file_exists( $located ), "File exists");
var_dump(file_get_contents($located));
// Allow 3rd party plugin filter template file from their plugin
$located = apply_filters( 'wc_get_template', $located, $template_name, $args, $template_path, $default_path );
do_action( 'woocommerce_before_template_part', $template_name, $template_path, $located, $args );
var_dump("After do_action function");
include $located;
var_dump("After the file is included");
do_action( 'woocommerce_after_template_part', $template_name, $template_path, $located, $args );
}

You'll also notice that I've edited the file I'm trying to include, so that it will fire another var_dump and print "Fired". But that expected output doesn't happen.
What could the cause of this issue be?
