Invalid Argument Error Making Search Bar - php

Question

I'm making a search bar for a site it works in one page but the other one I keep getting invalid argument error. Hopefully everything that is needed is below. I am using codeigniter. Please help. Thanks.
//Doesnt Work//
private function getUsers () {
$search = $this->input->post('search');
if($search && filter_var($search, FILTER_VALIDATE_EMAIL)) {
$where = 'WHERE source_adusers.ad_Email="'.$search.'"';
} else if ($search) {
$where = "WHERE source_adusers.ad_account='".$search."'";
} else if (!$search) {
$where = '';
}
$query = $this->db->query('SELECT *, COUNT(rollout_systems.EAM_USER) as systems FROM source_adusers
LEFT JOIN rollout_systems ON rollout_systems.EAM_User = source_adusers.ad_account '.$where.' GROUP BY source_adusers.ad_account LIMIT 0,50');
$users = null;
foreach ($query->result() as $row) {
$data['account'] = $row->ad_account;
$data['email'] = $row->ad_Email;
$data['name'] = $row->ad_DispName;
$data['systems'] = $row->systems;
$users[] = $data;
}
if(isset($this->data['users'])) {
$this->data['users'] = $users;
} else {
$this->data['users'] = $users;
}
}
//Does Work//
private function getSystems () {
$search = $this->input->post('search');
if ($search) {
$where = 'WHERE disc_systempool.ad_name="'.$search.'"';
} else {
$where = '';
}
$query = $this->db->query('SELECT *, COUNT(rollout_systems.sys_name) as scopes FROM disc_systempool LEFT JOIN rollout_systems
ON rollout_systems.sys_name=disc_systempool.ad_name '.$where.' GROUP BY disc_systempool.ad_name LIMIT 0,50');
foreach ($query->result() as $row) {
$data['model'] = $row->eam_Model;
$data['account'] = $row->ad_name;
$data['city'] = $row->eam_City;
$data['scopes'] = $row->scopes;
$data['search'] = $this->input->post('search');
$systems[] = $data;
}
if(isset($this->data['systems'])) {
$this->data['systems'] = $systems;
} else {
$this->data['systems'] = $systems;
}
}

Answer 1

It shows the right thing. I fixed the problem. I misunderstood what the guy that hired me asked me to do. He said search account name. I was search display name which kept giving me the error.

Answer 2

Try making a var_dump($data); inside your view. If empty. Do the same in your controller by just printing it out. If you see data inside the $data array. Make sure that you are sending the $data array with you into the view $this->load->view("view",$data);
Besides that, i might be wondering why you do foreach on your rows inside of the controller instead of just using the object right in your view
return $query->result();
in view
foreach($users as $user) { print $user->account; }
Hope you figure it out.
Best regards
