If $userchoice is false (see Table 1), then Perl checks the value of $systemchoice and so on until it gets to the last value, which is always used, whether it's true or not. 如果 $userchoice 为假(请参阅表 1),那么 Perl 就需要检查 $systemchoice 的值,依此类推,直到最后一个值,这个值通常都会被使用,不管它是真还是假。 - 2
This routine checks some of the fields in the form and collates the errors, and prevents the form from being submitted by returning false. 这个例程检查表单中的一些域并整理错误,还通过返回false防止表单被提交。 - 3
By default, when a validator returns false, the remaining validation checks are aborted, but that parameter is also configurable for each individual validator. 默认情况下,如果一个验证器返回false,则剩余的验证检查都将取消,但这个参数也可以对单个验证器进行配置。
