有一个电子商务商店运行ExpressionEngine和Expresso商店。我正试图获得适当的表单验证，但我一直遇到障碍。
Expresso Store文档是这样说的:
规则:field_name ="规则"
以及使用require="field_name"参数，越长safeccracker风格的语法也是可用的。对于每个字段，CodeIgniter表单验证规则可以指定。如果这个语法是在require="field_name"参数之外使用，两者都将适用。注意，order_email字段已经通过Valid_email规则，你不需要手动指定它。
文档给出的示例代码:
rules:billing_name="required"
rules:billing_phone="numeric"
rules:billing_postcode="required|min_length[5]|max_length[5]"
这意味着可以指定正常的CodeIgniter表单字段规则—例如regex_match。但在实践中，我无法让它起作用。也许我的Regex是错误的，但我还没有真正能够得到任何"规则"(如"数字"或"alpha")可靠地工作。实际上，我只是将billing_name设置为数字(所以只有数字)，并且输入了带空格的全名—绝对没有错误。
之前，我得到了一些错误-但只有当我使用字母数字，它会标记我正在使用的空格。但只适用于某些领域，而不适用于其他领域。
本质上，我真正想做的只是清除除空格、"."answers"-"以外的所有特殊字符。空格，句号和破折号。
也许我只是忽略了代码中的一些小问题。这是我第一次尝试在Expresso Store中应用CodeIgniter表单验证规则。
下面你看到的代码最终是我把任何我能扔进正则表达式的结果，只是为了得到一致的东西——错误或其他。

明白了。从本质上讲，CodeIgniter验证规则的运行方式与我预期的不同。某些角色会被筛选，而其他角色则不会。这是完全的用户错误。
