hi

attached is my custom field settings.


what i wish is for the vendor to select an option from the drop down. if he does not the system will call an error from the please select with no value.

im having the following errors

Warning: Creating default object from empty value in
/home.../administrator/components/com_hikamarket/classes/product.php on line 92

Warning: Attempt to assign property of non-object in /home.../components/com_hikamarket/views/productmarket/tmpl/form_image.php on line 43

Warning: Attempt to assign property of non-object in /home...components/com_hikamarket/views/productmarket/tmpl/form_image.php on line 42.

how can i have a please select option that will call an error if vendor does not pick from the drop down

thanks

hi

i tried this but the errors are still appearing.

i edited this file
/.../administrator/components/com_hikamarket/classes/product.php

i'm not sure if this is the file because no file was mentioned.

out of curiosity i tried this change

$product = $fieldsClass->getInput('product', $oldProduct, true, 'data', false, 'display:vendor_product_edit'); // 'all');
		if(empty($product))
			$ret = false;

$product = $fieldsClass->getInput('product', $oldProduct, true, 'data', false, 'display:vendor_product_edit'); // 'all');
		if(empty($product)) 
			return false;
