从Codeigniter中的$ _GET数据在数据库的最小值和最大值之间进行搜索

Question

I have a form that after submission my controller gets data from that form and sends to model to retrieve a result from database based on the _GET information.

In my form there are two fields called min-year and max-year that i use them to search in year column in the database between those numbers. The _GET array is like 'min-year'=>'something' and 'max-year'=>'something' after submission.

The _GET array is like 'min-year'=>'something' and 'max-year'=>'something' after submission.

Html:

<input type='text' name='state' />
<input type='text' name='min-year' />
<input type='text' name='max-year' />

controller:

$this->load->model('carinfo_model');
$where=($this->input->get());
$data['cars']=$this->carinfo_model->all_ad($where);

model:

public function all_ad($where){
->select("*")
->from("cars")
->where($where)         
$result=$this->db->get()->result_array();
return $result;
}

What is the fastest way to transform the _GET array into something readable for '->where()' to search in all other columns plus between min/max in year column in database?

I need a proper way to create a statement(string or array), that contains , all in one query from $_GET information if it's possible

Please note i have so many other input fields and this is just part of the form.

Answer 1

In View

<a href="<?php echo base_url() ?>Controller/Method/MinYear/MaxYead"></a>
<a href="<?php echo base_url() ?>welome/diff/2013/2016"></a>

In Controller

public function diff($min, $max) # Informing method there can be 2 input parameter from URL.
{
    $now = date("Y");
    $minYear = date_format('Y-m-d', $min.'-01-01');
    $maxYear = ($now == $max) ? date("Y-m-d") :  date_format('Y-m-d', $max.'-12-31');

    # in $maxYear if year is current year we cant take 2016-12-31. So we use Current timestamp.
    # If its not current year then we use 12-31. Ex 2014-12-31

}

Note: I have not tested this code with your purpose. Sometimes if date not worked in $minyear use with date() function like this $minYear = date(date_format('Ym-d', $min.'-01-01'));

EDIT 01

public function diff()
{
    $min = $this->input->get('min-year');
    $max = $this->input->get('max-year');
    $state = $this->input->get('state');  # updated

    $now = date("Y");
    $minYear = date_format('Y-m-d', $min.'-01-01');
    $maxYear = ($now == $max) ? date("Y-m-d") :  date_format('Y-m-d', $max.'-12-31');

    $data['cars'] = $this->carinfo_model->all_ad($minYear, $maxYear, $state);  # updated
}

In Model

public function all_ad($minYear, $maxYear, $state)  # updated
{
    $this->db->select(*);
    $this->db->from('cars');
    $this->db->where('field_name BETWEEN date($minYear) AND date($maxYear)');
    $this->db->where('field_name', $state ); # updated
    $query = $this->db->get();
    $result = $query->->result_array();
    return $result;
}

Answer 2

Try this.It's a controller function code. Paste this in your controller function and change the field name like your database table field name.

    $a = $this->input->get();
    $state = $a['state'];
    $min_yr = $a['min-year'];
    $max_yr = $a['max-year'];

    $where = "(field_name BETWEEN '$min_yr' AND '$max_yr') AND state = '$state'";

Send the where clause in your model function.

Answer 3

You can do some thing like below.

In controller get both value in different variable as given below:

$min_year = $this->input->get('min_year');
$max_year = $this->input->get('max_year');

then pass this variable into your model function like below:

$this->model_name->function_name($min_year,$max_year);

In model use between query as given below:

$sql = "SELECT * FROM table_name
WHERE year BETWEEN $min_year AND $max_year";
$result = $this->db->query($sql)->get()->result_array();

In $result you will get your result.
