Validate multiple input in CI 4 - ciddict - 03-10-2021
Hi,
This is the code in my controller:
PHP Code:
$fields = array(
"user_id[]" => "required"
);
print_r($this->request->getPost("user_id"));
$final_fields = array();
//to remove the fields if the post request doesn't found
foreach ($fields as $field => $validate) {
if (!is_null($this->request->getPost($field))) {
$final_fields[$field] = $validate;
}
}
if (!$final_fields) {
return true;
}
$validate = $this->validate($final_fields);
if (!$validate) {
$validation = \Config\Services::validation();
$message = $validation->getErrors();
echo json_encode($message);
exit();
}
I'm getting this output:
Code:
Array
(
[0] => 7
[1] => 17
)
{"user_id[]":"The user_id[] field is required."}Looking for help.
Thanks in advance.

Well, actually not sure why you have tried such complicated coding but I would go simpler
PHP Code:
$user_id => $this->request->getVar('user_id');
foreach ($user_id as $ui){
if($ui == ''){
$msg = 'User id should not be empty';
return redirect()->to(site_url('/admin/register'))->with('msg', $msg);
}
}
Btw, can you write more specifically what was your need and desired result?
RE: Validate multiple input in CI 4 - ciddict - 03-11-2021
@demyr,
You've used raw code for validation (not CI).
Simply, it's working well with,
PHP Code:
$fields = array(
"user_id" => "required"
);
But if there has multiple input with the single field like checkbox, the validation isn't working.
With this code:
PHP Code:
$fields = array(
"user_id[]" => "required"
);
It's shouldn't show this error,
Code:
{"user_id[]":"The user_id[] field is required."}While there has values,
Code:
Array
(
[0] => 7
[1] => 17

CodeIgniter 4 User Guide - Running Multiple Validations
permit_empty - Allows the field to receive an empty array, empty string, null or false.
RE: Validate multiple input in CI 4 - ciddict - 03-11-2021
@InsiteFX,
Thanks. But if I add permit_empty and no value found, it won't show error.
I mean, if this code:
PHP Code:
print_r($this->request->getPost("user_id"));
shows:
Code:
Array ()Then the validation should show the error what I want.
But after adding permit_empty it won't show error.

RE: Validate multiple input in CI 4 - ciddict - 03-12-2021
@kenjis, Can you please implement it for my case? I don't understand how to make this from your link: https://codeigniter4.github.io/CodeIgniter4/libraries/validation.html#validating-keys-that-are-arrays
RE: Validate multiple input in CI 4 - kenjis - 03-12-2021
I never tried it, but in your case:
PHP Code:
// The data to test:
'user_id' => [
0 => 7,
1 => 17,
]
$validation->setRules([
'user_id.*' => 'required'
]);
RE: Validate multiple input in CI 4 - ciddict - 03-13-2021
@kenjis, it worked. Thank you so much.

hi , is there a way to set_value on multiple field? i try to create a for cicle and use value='<?=set_value("serial_number[$i]")?>' but value is empty
edit:
work , for start to 1 array start to 0 now i start for from 0...
How can i validate min_length only if is set the field ( on multiple field)?
this is my rules :
Code:
$rules=
[
'seriale.*'=>[
'label'=>'Seriale',
'rules'=>'min_length[4]|is_unique[macchina.seriale]|seriale_corretto[seriale]',
'errors'=>[
'min_length'=>"Lunghezza minima Seriale 4 caratteri",
'is_unique'=>'Macchina già presente a magazzino' ,
'required'=>'Seriale obbligatorio',
'seriale_corretto'=>'Il Seriale inserito non è un seriale corretto!!!',
]
],
'codice_macchina.*'=>[
'label'=>'Codice macchina',
'rules'=>'min_length[0]|max_length[80]',
'errors'=>[
'min_length'=>'Lunghezza minima Codice macchina 0 caratteri',
'max_length'=>'Lunghezza massima Codice macchina 80 caratteri'
]
],
'id_clienti'=>[
'label'=>'Id clienti',
'rules'=>'min_length[0]|max_length[11]',
'errors'=>[
'min_length'=>'Lunghezza minima Id clienti 0 caratteri',
'max_length'=>'Lunghezza massima Id clienti 11 caratteri'
]
],
'id_documento_arrivo'=>[
'label'=>'Documento arrivo',
'rules'=>'required|max_length[11]',
'errors'=>[
'min_length'=>'Lunghezza minima Id documento arrivo 0 caratteri',
'required'=>'Documento arrivo obbligatorio'
]
],
];
