I have a view users where I have included both a modal form and a data table which populates from users table. I access the modal form via button. I have some validation in code igniter 4. When i enter all the fields correctly in the modal, the data is sent to the db but if i omit one field, upon redirection, I get an error [ErrorException Invalid argument supplied for foreach() on the users ] kindly help.
My Controller code ...
<?php
namespace App\Controllers;
use App\Models\userModel;
class UserController extends BaseController{
public function getData(){
$model=new userModel();
$data['userData']=$model->findAll();
return view('admin_template/users',$data);
}
public function insertUser(){
helper(['url']);
if($this->request->getMethod()==='post'){
$modeluser=new userModel();
$session=session(); //load session service
$data=[
"userName"=>$this->request->getVar("userName"),
"email"=>$this->request->getVar("email"),
"slocation"=>$this->request->getVar("slocation"),
"designation"=>$this->request->getVar("designation"),
"pwd"=>$this->request->getVar("pwd"),
"cpwd"=>$this->request->getVar("cpwd")
];
$validationRules=[
'userName'=>'required|min_length[5]|max_length[100]',
'email'=>'required|valid_email|is_unique[users.email]',
'slocation'=>'required',
'designation'=>'required',
'pwd'=>'required|min_length[5]|alpha_numeric',
'cpwd'=>'required|matches[pwd]'
];
$modeluser->setValidationRules($validationRules);
$fieldValidationMessage=[
'username'=>[
'required'=>'Name is required',
'min_length'=>'minimum length of name should be 5 chars',
'max_length'=>'maximum length of name should be 5 chars'
],
'email'=>[
'required'=>'Email is required',
'valid_email'=>'Enter a valid email',
'is_unique'=>'Email already exists'
],
'slocation'=>[
'required'=>'Location not selected',

'alpha_numeric'=>'password should contain alpha-numeric characters'
],
'cpwd'=> [
'required'=>'Confirm password cannot be empty',
'matches'=>' Confirm password does not match'
]
];
$modeluser->setValidationMessages($fieldValidationMessage);
if($modeluser->save($data)===false){
return view('admin_template/users',[
'errors'=>$modeluser->errors()
]);
} else{
$session->setFlashdata("success","User added successfully");
return redirect()->to(base_url('user'));

[The error]
CodePudding user response：
I solved the issue by passing my data to the method that returns validation errors to the view.
$modeluser->setValidationMessages($fieldValidationMessage);
$userdata = $this->getData();// called the method to get userdata.
if($modeluser->save($data)===false){
return view('admin_template/users',[$userdata,
'errors'=>$modeluser->errors() // Passed userdata to the view.
]);
} else {
$session->setFlashdata("success","User added successfully");
return redirect()->to(base_url('user'));
}
return view('admin_template/users');
