Hi,

I am trying to understand how to allow uploading of files using a developed component.

I created a XML form file for this

<?xml version="1.0" encoding="utf-8"?>
<form enctype="multipart/form-data">
        <fieldset
                addruleprefix="Spictera\Component\VolBilling\Administrator\Rule"
                addfieldpath="Spictera\Component\VolBilling\Field">
                <field
                        name="customer_id"
                        type="sql"
                        query="SELECT id AS value, customer_nm AS customer_id FROM #__volbilling_customers"
                        label="COM_VOLBILLING_REPORT_FORM_FIELD_CUSTOMER_NAME_LABEL"
                        description="COM_VOLBILLING_REPORT_FORM_FIELD_CUSTOMER_NAME_DESC"
                        required="true"
                />
                <field
                        name="upload_file"
                        type="file"
                        label="COM_VOLBILLING_REPORTER_FORM_FIELD_UPLOAD_FILE_NAME_LABEL"
                        description="COM_VOLBILLING_REPORTER_FORM_FIELD_UPLOAD_FILE_NAME_DESC"
                        size="40"
                        class="inputbox"
                        default=""
                />
        </fieldset>
</form>

But only the "customer_id" part is put on screen?

The "upload_file" is never appearing, so it is not even possible to give any input.

Where is this controlled? in the template files?

I use:

<?php echo $this->getForm()->renderField('customer_id'); ?>

But the file data is not in any tables, and should not be?

Do I have to use $_ variables for this? such as:

move_uploaded_file($_FILES[$params->get('efu_variable')]["tmp_name"]

Any one has a complete example of how this can be done in Joomla 4?

Thanks in advance

Presumably you also have a "renderField" for the upload_file field?

Once the files are input, in my controller I can access the list of files with

$files = $this->input->files->get('Filedata', [], 'array');

errr, does that give you what you need?

Hi,

I tried the suggestions, but the array returned is empty?

In the UploadreportController.php:

class UploadreportController extends FormController
{
        public function save($key = null, $urlVar = null)
        {
                $app = Factory::getApplication();
                $file = $app->input->files->get( 'file', null, 'raw');
                $files = $this->input->files->get('data', [], 'array');
                                                $mailer = Factory::getMailer();
                                                $user = Factory::getUser();
                                                $recipient = $user->email;
                                                $mailer->addRecipient($recipient);

                                                $body = "Hi,\n".var_export($app->input->files,true). ' name: '.$files . ' tmp: '.$file['tmp_name'];

                                                $mailer->setSubject('debug');
                                                $mailer->setBody($body);
                                                // $mailer->addAttachment(JPATH_COMPONENT.'/assets/document.pdf');

                                                // send the email
                                                $send = $mailer->Send();
                return false;

The email I receives has this data:

Hi,
Joomla\CMS\Input\Files::__set_state(array(
'decodedData' =>
array (
),
'inputs' =>
array (
),
'options' =>
array (
),
'filter' =>
Joomla\CMS\Filter\InputFilter::__set_state(array(
'stripUSC' => 0,
'tagsArray' =>
array (
),
'attrArray' =>
array (
),
'tagsMethod' => 0,
'attrMethod' => 0,
'xssAuto' => 1,
'blockedTags' =>
array (
0 => 'applet',
1 => 'body',
2 => 'bgsound',
3 => 'base',
4 => 'basefont',
5 => 'canvas',
6 => 'embed',
7 => 'frame',
8 => 'frameset',
9 => 'head',
10 => 'html',
11 => 'id',
12 => 'iframe',
13 => 'ilayer',
14 => 'layer',
15 => 'link',
16 => 'meta',
17 => 'name',
18 => 'object',
19 => 'script',
20 => 'style',
21 => 'title',
22 => 'xml',
),
'blockedAttributes' =>
array (
0 => 'action',
1 => 'background',
2 => 'codebase',
3 => 'dynsrc',
4 => 'formaction',
5 => 'lowsrc',
),
'blockedChars' =>
array (
0 => '&tab;',
1 => '&space;',
2 => '&colon;',
3 => '&column;',
),
)),
'data' =>
array (
),
)) name: tmp:

This is the form:

<?xml version="1.0" encoding="utf-8"?>
<form enctype="multipart/form-data">
        <fieldset>

                <field
                        name="myfile"
                        type="file"
                        label="Arquivo de Aniversariantes"
                        description="Arquivo na extensão .CSV com as colunas: NOME, DIA, MES"
                        size="200"
                        required="required"
                        accept="text/comma-separated-values, text/csv, application/csv, application/excel, application/vnd.ms-excel, application/vnd.msexcel, text/anytext"
                />
        </fieldset>
</form>

How do I get the form data from a file field?

The name of the file, where it is stored,etc?

Regards Tomas

Hello

Wrong name of field in form for upload files. In yours form field where user could put files have name -> myfile.
So....
$file = $app->input->files->get( 'myfile', null, 'raw');

Always U could check what have in $app->input by below code:

var_dump( $app->input );
die();
Pozdr

Hi,

That didn't work either, or I am not doing it rightly.

Dumping  does not show the files?
var_dump( $app->input->files );

    }
  }
  ["data":protected]=>
  &array(0) {
  }
}

But if I dump the $app->input, I can see the sample.csv gets listed, but under other structure.
But still no reference to where the files are located after upload? nor how to deal with the uploaded files?

Hi again,

If I dump the variables using

                var_dump( $app->input->get('jform') );
Than I got the name of the file submitted, but where is the data?

array(1) {
  ["myfile"]=>
  string(10) "sample.csv"
}
