Handling Multiple input with same field name as array. and show valdiation error

Hello,

I'm developing an employee management system, where i have to upload employee documents such as passport, id, etc... may be more documents in future. So i can't make static input fields.
Every document contain 3 common things suchs as (doc_no, doc_expiry_date, doc_type_id, doc_file).
I have implemented the form and doing the validation but, How i can display the error message if validation fails for appropriate document ?

Here is my form :

PHP Code:

<?php foreach ($doc_types as $doc): ?>

                    <div class="mb-3 col-md-6">
                        <div class="card">
                            <h5 class="card-header">
                                <?= $doc['name'] ?>
                            </h5>
                            <div class="card-body">
                                <div class="mb-3 row">
                                    <label for="" class="col-md-2 col-form-label">Doc No</label>
                                    <div class="col-md-10">
                                        <input class="form-control" placeholder="Enter Valid Doc No" name="doc_no[]"
                                            type="text" value="" id="html5-text-input">
                                    </div>
                                    <input type="hidden" name="doc_type[]" value="<?= $doc['id'] ?>">
<span class="error"><?=session('errros.doc_no')?></span>


                                </div>

                                <div class="mb-3 row">
                                    <label for="html5-text-input" class="col-md-2 col-form-label">Expiry Date</label>
                                    <div class="col-md-10">
                                        <input class="form-control" type="date" name="doc_expiry[]" value=""
                                            id="html5-date-input">

                                    </div>
                                </div>

                                <div class="mb-3 row">
                                    <label for="html5-text-input" class="col-md-2 col-form-label">File</label>
                                    <div class="col-md-10">
                                        <input class="form-control" type="file" id="formFile" name="file[]" multiple>
                                    </div>
                                </div>

                            </div>
                        </div>
                    </div>

                <?php endforeach; ?>

Here is my controller :

PHP Code:

public function documents()
    {
        $documents = new \App\Entities\DocumentsEntity;
        $doc_model = new DocumentsModel;


        if ($this->request->getPost()) {

            $count = count($this->request->getPost('doc_no')) - 1;

            $doc_files = $this->request->getFileMultiple('file');
            $doc_no = $this->request->getPost('doc_no');
            $doc_expiry = $this->request->getPost('doc_expiry');
            $doc_type = $this->request->getPost('doc_type');

            $data = [];

            for ($i = 0; $i <= $count; $i++) {

                if (!empty($doc_no[$i])) {
                    $data_record =

                        [
                            'no' => $doc_no[$i],
                            'expiry_date' => $doc_expiry[$i],
                            'doc_type_id' => $doc_type[$i],
                            'doc_file' => $doc_files[$i]->getName()

                        ];
                    array_push($data, $data_record);


                }
            }
            if (!empty($data)) {

                if ($doc_model->insertBatch($data) == TRUE) {

                    return redirect()->back()->with('warning', 'Success');
                } else {

                    return redirect()->back()
                        ->with('warning', 'Error')
                        ->with('errors', $doc_model->errors());

                }

            } else {


                return redirect()->back()
                    ->with('warning', 'Nothing to update !');
            }

        }

        $doc_types = new DocumentTypesModel;
        $doc_types = $doc_types->findAll();

        return view('employees/documents', [
            'doc_types' => $doc_types,

        ]);
    } 


So this form will display 6 section based on database entries for document type. I need to show the error message for appropriate section


If one section have error message it is showing to all section. see image below

No way. "insertBatch" returns the number of inserts or boolean.
You need to check the correspondence of the fields (empty, format, date...) before inserting and show the error earlier

Check this :

Code:

        $documents = new \App\Entities\DocumentsEntity;
        $doc_model = new DocumentsModel;
        $validation = \Config\Services::validation();


        if ($this->request->getPost()) {

            $count = count($this->request->getPost('no')) - 1;

            $doc_files = $this->request->getFileMultiple('doc_file');
            $doc_no = $this->request->getPost('no[]');
            $doc_expiry = $this->request->getPost('expiry_date[]');
            $doc_type = $this->request->getPost('doc_type[]');

            foreach ($doc_no as $ind => $val) {
                $validation->setRule('no[' . $ind . ']', 'Doc No', 'required');
                $validation->setRule('expiry_date[' . $ind . ']', 'Expiry date', 'required');
                $validation->setRule('doc_file[' . $ind . ']', 'Doc File', 'required');

            }

            $data = [];

            for ($i = 0; $i <= $count; $i++) {

                $data_record =

                    [
                        'no' => $doc_no[$i],
                        'expiry_date' => $doc_expiry[$i],
                        'doc_type_id' => $doc_type[$i],
                        'doc_file' => $doc_files[$i]->getName()

                    ];


                array_push($data, $data_record);






            }


            if (!$validation->run($data)) {


                return redirect()->back()->with('warning', 'Errors')->with('errors', $validation->getErrors());

            } else {


                if ($doc_model->insertBatch($data) == TRUE) {

                    return redirect()->back()->with('warning', 'Success');
                } else {

                    return redirect()->back()
                        ->with('warning', 'Error')
                        ->with('errors', $doc_model->errors());

                }

            }

        }

        $doc_types = new DocumentTypesModel;
        $doc_types = $doc_types->findAll();

        return view('employees/documents', [
            'doc_types' => $doc_types,

        ]);
    }

With the code you have, if you print_r or var_dump the errors session variable, you should able to get the "index" associated with the error message. So, your error message display should look something like this:

PHP Code:

<?= session('errors.doc_no.0') ?>

Where the 0 indicates the index.

Yes, now im able to show error messages. but my validation is not working. it always showing the error message if i enter the data also.

1. Are you validating in both the model and controller?

2. Within your controller, you do not need to load the validation library again. It is already available in controllers using $this->validate().

No, i'm doing in my controller only because, i have multiple error messages for different document types.

How i can workout this logic ?, Because in futre may be n number of document types will be added, so i can't put static fields
