foreach($ids as $id)
{
$this->db->select('*');

$this->db->where('userIdid',$id);
$row = $querys->result_array();

Answer 1

submit button should be the inside of closing form tag e.g.
<form>
<input type="submit" class="btn btn-pri1" value="Search" name="resume">
</form>
check if your Controller method is getting any Form POST array e.g.
<?php
function searchUser()
{
// make sure form is submitted
// With CodeIgniter’s built in methods you can simply do this:
if ($this->input->post()) {
// or PHP method
// if(isset($_POST) && !empty($_POST)){
// since the model method getsearchUsers don't have any input params
// no need to pass the inputs
$result['crud'] = $this->Crud->getsearchUsers();
// echo supports , separated statement too
echo '<pre>', print_r($result['crud']), '</pre>';
}
// show error that form is not submitted
die('Input Error: Please provide the valid inputs.');
}
?>
make sure there is no 403 error (CodeIgniter CSRF token because you
are using POST)
you can also use built-in 'where_in' to pass multiple where
conditions in your Model
<?php
function getsearchUsers()
{
// returns all post items with xss filter
$ids_array = $this->input->post('check', true);
$this->db->select('*');
$this->db->from('salary');
$this->db->where_in('userId', $ids_array);
// produces: WHERE userId IN ('1', '2')
$query = $this->db->get();
// check if records found
if ($query->num_rows() > 0) {
$row = $query->result_array();
// The $query result object will no longer be available
$query->free_result();
return $row;
}
// no record found
return FALSE;
}
?>
most important Always sanitize your users input before to use.
