Ajax issues

[Lievelabels.nlParticipant]

When PPOM plugin is enabled, I have issues with the following AJAX call:
../wp-admin/admin-ajax.php?action=tikkie-create-order
add_action( 'wp_ajax_tikkie-create-order', 'tk_create_order' );
This always returns 0 as the function is not actually called!

When I disable PPOM, it works without issues.
What could it be?

Hi,

well it does not make any sense to me that PPOM will stop any ajax call …

the only reason could be function tk_create_order is defined again in PPOM, which is never the case.

You are correct…. the function is called……. I need to check whats going on here…..
Added:
The function is only called, when no PPOM META is attached to the product.
Investigating further….

It seems one of the issues is the following:
echo '<input type="hidden" name="action" value="ppom_ajax_validation">';

[Lievelabels.nlParticipant]

Also, when we run:
$order_id = $checkout->create_order($checkout->get_posted_data()); from our ajax function,
We have output, like somewhere PPOM is echoing some data
Depending on the PPOM meta, it outputs several “0”

In our AJAX we return JSON, but depending on the amount of META, it is preceded by 0(‘s).

example:
`000{“checkoutUrl”:”https://URL”,”orderToken”:”XXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX”}

[Lievelabels.nlParticipant]

ok, I have found the issue where the 0 is coming from:
in wp-content/plugins/woocommerce-product-addon/inc/woocommerce.php

I see here some output, which causes problems:
echo $item->get_id();

function ppom_woocommerce_order_item_meta($item, $cart_item_key, $values, $order) {
	
	if ( ! isset ( $values ['ppom']['fields'] )) {
		return;
	}
	// ADDED WC BUNDLES COMPATIBILITY
	if ( function_exists('wc_pb_is_bundled_cart_item') && wc_pb_is_bundled_cart_item( $values )) {
		return;
	}
	
	$ppom_meta = ppom_make_meta_data( $values, 'order' );
	// ppom_pa($ppom_meta); exit;
	foreach( $ppom_meta as $key => $meta ) {
		
		echo $item->get_id();
		$item->update_meta_data($key, $meta['value']);
	}
	
	// Since 15.2, saving all fields as another meta
	$item->update_meta_data('_ppom_fields', $values ['ppom']);
}

in render-fields.php

// Hidden input for validation callback
echo '<input type="hidden" name="action" value="ppom_ajax_validation">';

Is this really needed? Or is this residu of old coding?

[Lievelabels.nlParticipant]
