Question

只是一个小问题，我想像这样构建查询

SELECT *
FROM users
WHERE MONTH( `birthday` ) = MONTH( '1999/05/19' )

现在，在我的PHP函数中，我想执行相同的操作，但是我从post变量获取此信息，在形成查询后，我的输出是这样的：

SELECT *
FROM `users`
WHERE MONTH(birthday) = 'MONTH(\"1999-05-19\")'

我想从代码中删除\。我的以下代码是：

$birthday = $this->input->post('birthday');
$where['MONTH(birthday)'] = 'MONTH('.'"'.$birthday.'"'.')';
$result = $this->User_model->getAnyData($where);

谁能告诉我哪里出错了？

Answer 1

使用如下给出的帮助

$birthday = $this->input->post('birthday'); 
$where['MONTH(birthday)'] = "MONTH(".$birthday.")";
$result = $this->User_model->getAnyData($where);

Answer 2

如果POSTed数据包含反斜杠，请使用PHP stripslashes()删除它们：http://php.net/manual/en/function.stripslashes.php。

Answer 3

取决于您的字符串是用单引号还是双引号括起来取决于您的操作：

<?php
$sql = 'SELECT *
FROM `users`
WHERE MONTH(birthday) = MONTH("1999-05-19")';

应该有效。也：

<?php
$sql = "SELECT *
FROM `users`
WHERE MONTH(birthday) = MONTH('1999-05-19')";

Answer 4

要删除单引号，您需要在活动记录中传递false参数。

$this->db->where('MONTH(birthday)', 'MONTH(YOUR_DATA)', FALSE);

所以查询就像：

$this->db->select('*');
$this->db->from('TABLE_NAME');
$this->db->where('MONTH(birthday)', 'MONTH(YOUR_DATA)', FALSE);

Answer 5

尝试使用此功能，仅提取一个月。

 $birthday = $this->input->post('birthday');
            $birthday = DateTime::createFromFormat('d/m/Y', $birthday)->format('m');

            $where['MONTH(birthday)'] = $birthday;
            $result = $this->User_model->getAnyData($where);

SELECT * FROM users WHERE MONTH( `birthday` ) = '05 ';
