Question

我正在为我的网站构建一个扬声器表单，它基本上只是从用户那里获取输入的数据并将其放入数据库中。该网站还允许您保存或提交表格，我使用

检查

if(isset($_POST['save'])

我遇到的问题是，当我将一些文本框留空并点击＆＃34; save＆＃34;时，数据库会出错说：

( ! ) PDOException: SQLSTATE[HY000]: General error: 1366 Incorrect integer value: '' for column 'phone_number' at row 1 in C:\wamp64\www\rotarywebsite\speakerform.php on line 98

我检查了代码和数据库，看看我发现研究中是否有错误拼写或其他任何错误的数据库。所以基本上我希望允许用户＆＃34;保存＆＃34;表格同时也留下一些文本框空白。这是我的代码和SQL格式

PHP代码

Answer 1

由于phone_number被声明为INT字段，因此必须为其提供有效的整数值，并且空字符串不是有效的整数。

您可以使用0替换空字符串。

$phone_number = trim($_POST['phone_number']);
if ($phone_number == '') {
    $phone_number = 0;
}

但最好的解决方案是将数据库中的此字段更改为VARCHAR。电话号码不是真正的数字，它们通常有其他字符，例如+1 (202) 555-1212。

Answer 2

您将数据库中的所有字段设置为NOT NULL。这意味着insert语句必须包含每个字段的有效值。您需要从那些您想要选择的字段中删除NOT NULL约束。

Answer 3

尝试从要保持为空的属性中删除NOT NULL。例如- 尝试更改 - fullname varchar（200）NOT NULL， phone_number int（200）NOT NULL， 到 - fullname varchar（200）， phone_number int（200），

PHP - 不正确的整数值
