问题在于,当显示第二个表单时,验证不会按照我需要的方式进行。无论我在TextBoxEntry
中是否有值,我都会收到消息Saved
。理想情况下,如果文本框不为空,那么只有我应该收到消息Saved
,但即使我没有任何内容,我也会收到消息Saved
有人可以帮忙吗?
由于
以下是代码:
<?php
SESSION_start();

更改if(!(isset($_POST['TextBoxEntry']) || $_POST['TextBoxEntry'] == ''))
到
if( !isset($_POST['TextBoxEntry']) || $_POST['TextBoxEntry'] == '')
答案 1 :(得分:0)
尝试
if(empty($_POST['TextBoxEntry']))
{
echo $_SESSION['cb'];
echo "Empty!";
} else {
echo $_SESSION['cb'];
echo "Saved!";
}
我刚刚意识到'TextBoxEntry'是一个数组。 希望它有所帮助。
干杯!!

if(!(isset($_POST['TextBoxEntry']) || $_POST['TextBoxEntry'] == ''))
等于if(!isset($_POST['TextBoxEntry'] && $_POST['TextBoxEntry'] != '')
,但您需要将其更改为
if(!isset($_POST['TextBoxEntry'] || $_POST['TextBoxEntry'] == '')
另一件事是我认为您的代码中不需要return
语句。
答案 3 :(得分:0)
而不是这行代码
if(!(isset($_POST['TextBoxEntry']) || $_POST['TextBoxEntry'] == ''))
你应该有这个
if( (!(isset($_POST['TextBoxEntry'])) || $_POST['TextBoxEntry'] == ''))
因为当你拥有代码时,程序会取消所有条件。所以你需要另一个()来保持第一部分的否定。
试试这件事。希望它有效!
