insert form input value in database in php

Question

I have one form input like

 <input type="text" class="form-control" name="SITE_URL" id="SITE_URL" required> 

So what I want is to add name's value SITE_URL in one database column and the value I insert in other column like

v_name      l_value
---------- ----------
SITE_URL  "Inserted value "

l_value is inserted completely but v_name is not inserted my $_post array is like:

Array
(
    [SITE_URL] => value that i inserted
)

My code is:

if($_SERVER['REQUEST_METHOD'] == "POST"){
        $post["l_value"] = $this->input->post('SITE_URL');
        $post["v_name"] = $this->input->post('');
        $addPage = $this->admin_model->addSiteSetting($post);
        exit;

}

And addSiteSetting function is:

 public function addSiteSetting($ins){

    $this->db->insert('tbl_setting', $ins);
    return 1;
}

Answer 1

You should pass SITE_URL as static name for $post["v_name"]

you need to change just one line $post["v_name"] = $this->input->post(''); To $post["v_name"] = 'SITE_URL';

if($_SERVER['REQUEST_METHOD'] == "POST"){
        $post["l_value"] = $this->input->post('SITE_URL');
        $post["v_name"] = 'SITE_URL';
        $addPage = $this->admin_model->addSiteSetting($post);
        exit;
}

Answer 2

You can process $_POST in foreach loop to get both names and their values, like this:

if($_SERVER['REQUEST_METHOD'] == "POST"){
      $post = array();
      foreach ($_POST as $name => $value) {
      $post["l_value"] = $value;
      $post["v_name"] = $name;
      }

        $addPage = $this->admin_model->addSiteSetting($post);
        exit;
}

Answer 3

You just need to remove the following line. Because here you store the blank value into the v_name. That's why v_name doesn't get any value and keep it empty.

$post["v_name"] = $this->input->post('');

And Instead of the above line you need to add this line:

$post["v_name"] = 'SITE_URL';

Answer 4

You have

$post["l_value"] = $this->input->post('SITE_URL');
    $post["v_name"] = $this->input->post('');

remove

$post["v_name"] = $this->input->post('');
