Class BootstrapFormRow line: 74
$classString = 'form-check-input';
Causes the checkbox to overlap the label making it unreadable. The following change fixes it for me in Firexfox Developer Edition and the most recent Google Chrome. Both on windows 10
$classString = 'form-check';

When using the helper with a Captcha element in a form there is an undefined index reported on line 138 due to $type being null. Adding !empty($type) appears to have fixed it for me. If I run into any problems I will updated the issue. Check is on line 94.

Thanks for your books, the one for ZF3 and now this one published last month. I was hoping to use a LAMP server to follow along the chapters. One question I had is in chapter two, upon enabling the display of all errors, I get blank white pages when using Centos 8. Is this pretty common? I had another concern about international extension but have learned this is done differently when using Centos8.

Argument 1 passed to Application\Model\AbstractTable::saveRow() must be an instance of Application\Model\Rowset\AbstractModel, instance of Application\Model\Rowset\User given, called in Application\src\Model\UsersTable.php on line 23

Thanks for your books, the one for ZF3 and now this one published last month. I was hoping to use a LAMP server to follow along the chapters. One question I had is in chapter two, upon enabling the display of all errors, I get blank white pages when using Centos 8. Is this pretty common? I instead enabled display_errors in php.ini but am not sure if that is acceptable practice. Another question I had was, instead of enabling the Intl PHP extension by uncommenting the line that says ;extension=intl, I could instead install something called php74-php-intl.x86_64 ?

I am appending a sort of protocol I have been using in case it might help... after nearly a dozen tries this is what seems to work...

From within /home/phpcat ... seems to be the only place this will work from...

sudo chown phpcat /var/www/html/laminas_app
composer create-project -s dev laminas/laminas-mvc-skeleton /var/www/html/laminas_app
#Now when I visit http://lamp.localdomain/laminas_app/public/ I see the Laminas MVC Skeleton welcome page.
sudo yum list php7*intl

#I can stil see the Laminas MVC Skeleton welcome page and toolbar!

Hello everybody, Olmalek,

thanks for book.

can not download using composer1 to 2: divix1988/laminas-twig-module": "^1.1"
(this problem are in many Chapiters of book but form me is important in Chapitre 14 Chapitre 15 Chapitre 16)

1. Many bug with library are often do beacause i used Composer version 2 but i rollback to Composer 1 but big problems

Solution: i have tried many versions of composer (version 1.0 to version 2 ...) with command in CMD :
CMD ==> composer self-update -- 1.0
CMD ==> composer self-update -- 1.10.19 (i test many version 1 of Composer until version 2 and last)

but your divix1988/laminas-twig-module is not in Composer and can you add this library to Composer?

For each version i launch in (version 1 to 2...):
CMD ==> composer upgrade (to download library in composer.json in the root of website)
CMD ==> composer info or composer show (but composer didn't find the library divix1988/laminas-twig-module)

2. Which version of Composer dio you use for the book?

Thanks

Hello everybody; Olmalek,

problem: "zf-commons/zfc-admin": "dev-I-laminas-migration"

with version Composer 2

Solution: never use Version 2 Composer but maximum version Composer 1.10.19

to change version of Composer for example to version Composer 1.10.19
CMD ==> composer self-update -- 1.10.19

Line 71 of BootstrapFormRow:
if ($element instanceof Submit)
The following fixes the issue for me:
if ($element instanceof Submit || $element instanceof Button)
The button class is listed in the use statements which makes me think it might have just been an oversight :)
