Question

目前我在codeigniter中创建了一个管理员问题。

不让我从表单中创建用户。我有一个SQL语法错误。并且不确定如果首次安装，如何确保将user_id设置为1.

错误

Error Number: 1064

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE `username` = 'admin'' at line 2

SELECT * WHERE `username` = 'admin'

Filename: C:\xampp\htdocs\codeigniter-cms\system\database\DB_driver.php

Line Number: 330

在模型上

function adminuser() {
$this->db->where('username', $this->input->post('username'));
$query = $this->db->get($this->input->post('database'));

if($query->num_rows > 0){

echo '<div class="alert alert-error"><a class="close" data-dismiss="alert">×</a><strong>';
echo "Username already taken";  
echo '</strong></div>';

}else{

$query_user = array(
'username' => $this->input->post('username'),
'password' => sha1($this->input->post('password')),
'email' => $this->input->post('email')
);

$insert = $this->db->insert($this->input->post('database'), $query_user);
return $insert;
}
}

我建议您学习ActiveRecord文档页面。 http://ellislab.com/codeigniter/user-guide/database/active_record.html

您错过了FROM ...在输出错误消息中非常清楚。

试试这个，

$username = $this->input->post('username');
$query = $this->db->get_where('mytable', array('username' => $username));

不要让我创建用户codeigniter
