我正在尝试将货币数据存储在mysql中。在这里,我使用了decimal
和double
数据类型。
这是我的表结构:
CREATE TABLE IF NOT EXISTS transactions (
tb_id INT UNSIGNED NOT NULL AUTO_INCREMENT,
tb_our_rate DECIMAL(15, 2) NOT NULL,
tb_bank_rate DECIMAL(15, 2) NOT NULL,
tb_lkr_funds DOUBLE(15, 2) NOT NULL,
tb_aud_funds DOUBLE(15, 2) NOT NULL,
PRIMARY KEY (tb_id)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
我尝试在这些列中插入一些值。这是我插入的值。
133.11
120.20
-12312,123,123.02
-12312,231,423.32
这是它插入数据库的方式:
mysql> select * from transactions\G
*************************** 1. row ***************************
tb_our_rate: 13311.00
tb_bank_rate: 12020.00
tb_lkr_funds: -1231212312302.00
tb_aud_funds: -1231223142332.00
date_added: 2015-11-26 07:36:01
*************************** 2. row ***************************
更新: 这就是我的插入查询的工作方式:
$our_rate = filter_input(INPUT_POST, 'our_rate', FILTER_SANITIZE_NUMBER_FLOAT);
$bank_rate = filter_input(INPUT_POST, 'bank_rate', FILTER_SANITIZE_NUMBER_FLOAT);
$lkr_funds = filter_input(INPUT_POST, 'lkr_funds', FILTER_SANITIZE_NUMBER_FLOAT);
$aud_funds = filter_input(INPUT_POST, 'aud_funds', FILTER_SANITIZE_NUMBER_FLOAT);
$query = "INSERT INTO transaction_banks(
tb_our_rate
, tb_bank_rate
, tb_lkr_funds
, tb_aud_funds
, date_added
) VALUES (?, ?, ?, ?)";
$insert_stmt = $mysqli->prepare($query);
if ($insert_stmt){
$insert_stmt->bind_param('dddd',
$our_rate
, $bank_rate
, $lkr_funds
, $aud_funds
);
$insert_stmt->execute();
}
有谁能告诉我这是什么问题?

删除FILTER_SANITIZE_NUMBER_FLOAT
。这会删除输入中的.
。
选中https://maven.apache.org/plugins/maven-dependency-plugin/examples/purging-local-repository.html。
它会对输入进行清理,并且只允许+
和-
。
您可以使用FILTER_FLAG_ALLOW_FRACTION
:
$our_rate = filter_input(INPUT_POST, 'our_rate', FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION);
$bank_rate = filter_input(INPUT_POST, 'bank_rate', FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION);
$lkr_funds = filter_input(INPUT_POST, 'lkr_funds', FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION);
$aud_funds = filter_input(INPUT_POST, 'aud_funds', FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION);
检查documentation之前有关此问题的问题。

这对我来说很好看。不要在数字中使用逗号插入。我甚至害怕尝试。
create table thing99
( id int auto_increment primary key,
tb_our_rate DECIMAL(15, 2) NOT NULL,
tb_bank_rate DECIMAL(15, 2) NOT NULL,
tb_lkr_funds DOUBLE(15, 2) NOT NULL,
tb_aud_funds DOUBLE(15, 2) NOT NULL
);
insert thing99(tb_our_rate,tb_bank_rate,tb_lkr_funds,tb_aud_funds) values
(133.11,120.20,-12312123123.02,-12312231423.32);
select * from thing99;
+----+-------------+--------------+-----------------+-----------------+
| id | tb_our_rate | tb_bank_rate | tb_lkr_funds | tb_aud_funds |
+----+-------------+--------------+-----------------+-----------------+
| 1 | 133.11 | 120.20 | -12312123123.02 | -12312231423.32 |
+----+-------------+--------------+-----------------+-----------------+
刚刚找到它。你必须使用下面的选项2.
$our_rate = filter_input(INPUT_POST, 'our_rate', FILTER_SANITIZE_NUMBER_FLOAT);
$our_rate2=filter_input(INPUT_POST,'our_rate',
FILTER_SANITIZE_NUMBER_FLOAT,FILTER_FLAG_ALLOW_FRACTION);
echo $our_rate."<br>";
echo $our_rate2."<br>";
