function salesforce_api_update_wsdl_form_validate in Salesforce Suite 6.2

Same name and namespace in other branches

1. 7.2 salesforce_api/salesforce_api.admin.inc \salesforce_api_update_wsdl_form_validate()

Validate the WSDL file upload - check upload error code and file extension and do the actual upload processing so that we can invalidate the form on any errors. This function SHOULD use file_save_upload(), but unfortunately, that function calls file_create_path() which calls file_check_location(), which fails on any destination dir that isn't in the default file upload dir. And since the enterprise.wsdl.xml file needs to go into a sub-dir in the module directory, that won't do. Instead of uploading to the default dir, then moving, just upload it straight to the destination.
