2.3 => 2.4

Update checklist

• app/presenters/Admin/templates/Partials/tinymce.js does not have {contentType javascript}

• Rewrite the old submit button from $form->submitted to use the new $form->isSubmitted().

• Missing setRequired(true | false) => must be filled in for each use of "addRule"

• Deprecated fce array_key_exists() (for objects) -> in models replace with property_exists() and swap parameters

  • regex: array_key_exists\((.*?), (.*?)\)

  • replace: property_exists($2, $1)

• Deprecated nl2br filter -> add to config "- addFilter('nl2br', 'nl2br')"
• Use tomaj/nette-bootstrap-form instead of bootstrap-3-renderer
• Somewhere is not checked via isset() or !empty()
• Rewrite old php code in latte: {?...} => {php...}
• Old notation of the |noescape filter with !. Fix using:
  • regex: \{\!(.*?)\}
  • replace: {$1\|noescape}
  • Check if the filter is present somewhere 2x
• With $cookieVariant variable (on Front in the layout) |noescape can be broken
• In the updated translation there is a wrong vendor/symfony/translation/Translator.php/getLocale() (delete marked)
• "undefined variable $web"
• In the product preview the Description filter did not check if $page['options]['properties'] is not an empty array (see picture below) + some translations in db were missing (for now only commented (commit 2313e072) + PROPERTY_FRONT_COLOR_X_COLOR I added from drevojnew)
