问题描述

我正在创建一个提名页面,如果有任何字段填写,我想通过

通过,但如果没有填写,则

消息将会出现。我不能在多个

字段上进行检查。


这是我所拥有的:

if ($ nominee_first_name!==''''&& $ nominee_middle_initial!==''''&&

$ nominee_last_name!=='''')


如果所有字段都有内容,页面都会通过,那么我所关心的是至少有一个输入的内容

字段。

解决方案

nominee_first_name!==''''&&


< blockquote> nominee_middle_initial!==''''&&


nominee_last_name!=='''')


会发生的是,如果所有字段都有内容,则页面会通过,而且我关心的是至少有一个

字段中输入的内容。


I am creating a page for nomination and want to let the information
pass if any field are filled out, but if none are filled out, a
message will appear. I can''t get the check to happen on multiple
fields though.

Here is what I have:
if ($nominee_first_name !=='''' && $nominee_middle_initial !=='''' &&
$nominee_last_name !=='''')

What happens is that if all fields have content, the page passes, and
all I care about is that there is something entered in at least one
field.

解决方案

nominee_first_name !=='''' &&


nominee_middle_initial !=='''' &&


nominee_last_name !=='''')

What happens is that if all fields have content, the page passes, and
all I care about is that there is something entered in at least one
field.
