How do I add a custom placeholder to the FormIt hook?

[AlexandrWD]

The site has a form for ordering price lists. They are taken from the directory in the site directory.
I go through and generate links like this:

$dir = 'prices';
    if ( $handle = opendir( $dir )
    {
        while ( $file = readdir($handle) )
        {
         for ($i=0; $i<count($file); $i++)
            if(($file != '.') && ($file != '.') && ($file[0] != '.')) {
                $file = mb_convert_encoding($file, "utf-8", "windows-1251");
                $file = '<br /><a href="https://.../prices/'.$file.'">'.$file.'</a>';
                $fileOrder[] = $file;
            }
        };
        closedir( $handle );
    };

The whole hook with sending the email looks like this:

<?php
    $fields = $hook->getValues();
    
    $message = $modx->getChunk('tpl.mail.price', $fields);
     
    $modx->getService('mail', 'mail.modPHPMailer');
    $modx->mail->set(modMail::MAIL_BODY, $message);
    $modx->mail->set(modMail::MAIL_FROM, $modx->getOption('emailsender'));
    $modx->mail->set(modMail::MAIL_FROM_NAME, $modx->getOption('site_name'));
    $modx->mail->set(modMail::MAIL_SUBJECT, 'Price List');
    $modx->mail->address('to', $fields['email']);
    $modx->mail->address('reply-to', $modx->getOption('emailsender'));
    $modx->mail->setHTML(true);
    
    $dir = 'prices';
    if ( $handle = opendir( $dir )
    {
        while ( $file = readdir($handle) )
        {
         for ($i=0; $i<count($file); $i++)
            if(($file != '.') && ($file != '.') && ($file[0] != '.')) {
                $file = mb_convert_encoding($file, "utf-8", "windows-1251");
                $file = '<br /><a href="https://.../prices/'.$file.'">'.$file.'</a>';
                $fileOrder[] = $file;
            }
        };
        closedir( $handle );
    };
    
    $hook->setValue('fileOrder', $fileOrder);
    
    if (!$modx->mail->send()) {
      $modx->log(modX::LOG_LEVEL_ERROR,'An error occurred while trying to send the email: '.$modx->mail->mailer->ErrorInfo);
    }
    
    $modx->mail->reset();
    
    return true;

In the email I call the placeholder like this:
[[+fileOrder]]

.

Calling a snippet

[[!AjaxForm?
    &snippet=`FormIt`
    &form=`tpl.price.form`
    &hooks=`hookSendFile`
    &validate=`email:minLength=^4^,inputt:blank`
]]

As a result, I get an email with the text “[[+fileOrder]]” instead of an array.

How do I make a hook send a placeholder?

I apologize for the mistakes. I use a translator.

Order is important, try this please:

$fields = $hook->getValues();

$modx->getService('mail', 'mail.modPHPMailer');
$modx->mail->set(modMail::MAIL_BODY, $message);
$modx->mail->set(modMail::MAIL_FROM, $modx->getOption('emailsender'));
$modx->mail->set(modMail::MAIL_FROM_NAME, $modx->getOption('site_name'));
$modx->mail->set(modMail::MAIL_SUBJECT, 'Price List');
$modx->mail->address('to', $fields['email']);
$modx->mail->address('reply-to', $modx->getOption('emailsender'));
$modx->mail->setHTML(true);

$dir = 'prices';
if ( $handle = opendir( $dir )
{
    while ( $file = readdir($handle) )
    {
     for ($i=0; $i<count($file); $i++)
        if(($file != '.') && ($file != '.') && ($file[0] != '.')) {
            $file = mb_convert_encoding($file, "utf-8", "windows-1251");
            $file = '<br /><a href="https://.../prices/'.$file.'">'.$file.'</a>';
            $fileOrder[] = $file;
        }
    };
    closedir( $handle );
};

//$hook->setValue('fileOrder', $fileOrder);
$fields['fileOrder'] = implode(",", $fileOrder);// or other look for pure array,just an idea how to pass the value
$message = $modx->getChunk('tpl.mail.price', $fields);
 


if (!$modx->mail->send()) {
  $modx->log(modX::LOG_LEVEL_ERROR,'An error occurred while trying to send the email: '.$modx->mail->mailer->ErrorInfo);
}

$modx->mail->reset();

return true;

In your case, the letter does not come in the mail. But if I understood correctly, I made the snippet like this, only the result did not change

$fields = $hook->getValues();

$dir = 'prices';
if ( $handle = opendir( $dir ) )
{
    while ( $file = readdir($handle) )
    {
     for ($i=0; $i<count($file); $i++)
        if(($file != '.') && ($file != '..') && ($file[0] != '.')) {
            $file = mb_convert_encoding($file, "utf-8", "windows-1251");
            $file = '<br /><a href="https://.../prices/'.$file.'">'.$file.'</a>';
            $fileOrder[] = $file;
        }
    };
    closedir( $handle );
};

$hook->setValue('fileOrder', $fileOrder);

$message = $modx->getChunk('tpl.mail.price', $fields);
 
$modx->getService('mail', 'mail.modPHPMailer');
$modx->mail->set(modMail::MAIL_BODY, $message);
$modx->mail->set(modMail::MAIL_FROM, $modx->getOption('emailsender'));
$modx->mail->set(modMail::MAIL_FROM_NAME, $modx->getOption('site_name'));
$modx->mail->set(modMail::MAIL_SUBJECT, 'Прайс-лист');
$modx->mail->address('to', $fields['email']);
$modx->mail->address('reply-to', $modx->getOption('emailsender'));
$modx->mail->setHTML(true);

if (!$modx->mail->send()) {
  $modx->log(modX::LOG_LEVEL_ERROR,'An error occurred while trying to send the email: '.$modx->mail->mailer->ErrorInfo);
}

$modx->mail->reset();

return true;

Added information about calling the snippet to the post

As @himurovich wrote, add fileOrder to your $fields-array ($fields['fileOrder'] = implode(",", $fileOrder);) instead of using $hook->setValue('fileOrder', $fileOrder);.

Or maybe reordering the lines like this may also work:

...
$hook->setValue('fileOrder', $fileOrder);
$fields = $hook->getValues();
$message = $modx->getChunk('tpl.mail.price', $fields);
