我使用时
echo "<pre>";
print_r($showdata);
在我的浏览页面中出现错误
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: se_ct ........
这是将值从视图传递到控制器到模型的正确方法吗？我不确定我的控制器是否将值传递给模型，我也不确定模型页面。
答案 0 :(得分：1)
我正在根据你的问题谈论错误，所以以下是我的意见。
我认为下面的问题
$data['results']=$query->result();
它应该像
$data['results']=$query->result_array();
然后执行以下操作
echo "<pre>";
print_r($showdata);
它不会显示任何错误。过程不正确。你应该把控制器中的所有值都像@Aeolun所说，然后在函数中传递它。
并且您的模型函数应该看起来像
model function login($look,$age,$se_ct,$subsect,$coun_try, $sta_te, $ci_ty,$qualification)
从函数中删除$ per_page = 3，因为你将它定义为3.所以不需要将它作为参数传递。
如果您需要什么，请告诉我。
/ *更新* /
控制器功能
$look = $this->input->post('gender');
$age_from = $this->input->post('age_from');
$age_to = $this->input->post('age_to');
$age = $this->input->post('age');
$se_ct = $this->input->post('sect');
$subsect = $this->input->post('subsect');
$coun_try = $this->input->post('country');
$sta_te = $this->input->post('state');
$ci_ty = $this->input->post('city');
$qualification = $this->input->post('qualification');
$data['showdata'] = $this->searchresultss->login($per_page=3,$look,$age, $age_to,$age_from,$se_ct,$subsect,$coun_try, $sta_te, $ci_ty,$qualification);
和模型功能
model function login($per_page,$look,$age,$age_to,$age_from,$se_ct,$subsect,$coun_try, $sta_te, $ci_ty,$qualification)
，您的查询应该是
$query="SELECT *
FROM users
WHERE
if('$se_ct'!='',sect = '$se_ct' AND if('$subsect' !='',subsect = '$subsect',subsect like '%%'),sect like '%%' AND subsect like '%%')
AND
IF( '$coun_try' !='', country = '$coun_try'
AND
if('$sta_te' !='', state = '$sta_te'
AND
if('$ci_ty' !='',city = '$ci_ty',city like '%%'),state LIKE '%%'
AND city LIKE '%%'), country LIKE '%%'
AND state LIKE '%%'
AND city LIKE '%%' )
AND age >= '$age_from'
AND age <= '$age_to'
AND
IF('$qualification' !='',qualification = '$qualification', qualification LIKE '%%' )
AND gender = '$look'
And status='1'";
$data=array();
$query=$this->db->query($query);
$data['results']=$query->result_array();
$data['count']=$query->num_rows();
$data['pages']=ceil($data['count']/3); // if $per_page is undefined the make it 3;
答案 1 :(得分：0)
在我看到的情况下，你在控制器，视图和模型之间传递值的方法是正确的，除了你缺少所有输入参数，除了＆quot; per_page＆＃39;，你应该全部添加到模型中功能
//IN MODEL
function login($sect, $country, $state, $city, $per_page=3)
然后，当您将这些参数添加到模型函数中时，您可以使用以下命令从请求中获取它们：
//IN CONTROLLER
$sect = $this->input->post('sect');
$country = $this->input->post('country');
$state = $this->input->post('state');
$city = $this->input->post('city');
$this->searchresultss->login($sect, $country, $state, $city);
您的模型中的查询中也存在潜在的SQL注入漏洞，请使用Codeigniter中内置的参数工具。例如：
//IN MODEL
$query="select * from users where country = ? AND sect = ? AND state = ? AND city = ? limit ?";
$query=$this->db->query($query, [ $country, $sect, $state, $city, $per_page ]);
此外，您在视图中直接使用其他SQL查询，您可能希望将其移至已有的模型或其他模型。
请注意：我没有使用您表单中的所有字段，因为我认为这会使示例不清楚，但您可以使用相同的方法添加其余字段。
