hi there
i am building my own theme and tried to add a grid framework to the theme.
i followed these instructions and added the lines which were described:
but i still get the error:
No grid framework found. Grid area methods require a valid grid framework defined in a PageTheme class.
can anyone help? my page_theme.php has really only these lines in it:
<?php
namespace Application\Theme\MyTheme;
use Concrete\Core\Page\Theme\Theme;
class PageTheme extends Theme
{
}
The tutorial you followed says, under section “Add Grid Support to the Class File”, that you have to add this line to your file:
protected $pThemeGridFrameworkHandle = 'bootstrap3';
And replace bootstrap3 wit the handle you gave your own framework
hi mnakaly
thank you very much for your feedback!
i added this line in the page_theme.php but nothing happened – same error.
Could you share your whole code here? not just page_theme.php, the whole thing.
basically i have a theme made bymyself which works fine.
i just wanted to have the possibility to add containers and custom styles in the wysiwyg editor.
this is my page_theme.php
<?php
namespace Application\Theme\Snf2024;
class PageTheme extends \Concrete\Core\Page\Theme\Theme
class PageTheme extends Theme
{
protected $pThemeGridFrameworkHandle = 'bootstrap5';
}
public function getThemeEditorClasses()
{
return [
['title' => t('Title Thin'), 'menuClass' => 'title-thin', 'spanClass' => 'title-thin', 'forceBlock' => 1],
['title' => t('Title Caps Bold'), 'menuClass' => 'title-caps-bold', 'spanClass' => 'title-caps-bold', 'forceBlock' => 1],
['title' => t('Title Caps'), 'menuClass' => 'title-caps', 'spanClass' => 'title-caps', 'forceBlock' => 1],
['title' => t('Image Caption'), 'menuClass' => 'image-caption', 'spanClass' => 'image-caption', 'forceBlock' => '-1'],
['title' => t('Standard Button'), 'menuClass' => '', 'spanClass' => 'btn btn-default', 'forceBlock' => '-1'],
['title' => t('Success Button'), 'menuClass' => '', 'spanClass' => 'btn btn-success', 'forceBlock' => '-1'],
['title' => t('Primary Button'), 'menuClass' => '', 'spanClass' => 'btn btn-primary', 'forceBlock' => '-1'],
];
}
and this is my default.php:
<?php
defined('C5_EXECUTE') or die("Access Denied.");
$this->inc('elements/header.php');
?>
<main>
<?php
$a = new Area('Main');
$a->enableGridContainer();
$a->display($c);
$a = new Area('Page Footer');
$a->enableGridContainer();
$a->display($c);
?>
</main>
<?php
$this->inc('elements/footer.php');
There’s an error in your code.
The closing bracket } you have after $pThemeGridFrameworkHandle shouldn’t be there. Remove it and put it at the end after the last closing bracket.
thank you very much for your feeback!
I still get this error… 
No grid framework found. Grid area methods require a valid grid framework defined in a PageTheme class.
<?php
namespace Application\Theme\Snf2024;
class PageTheme extends \Concrete\Core\Page\Theme\Theme
class PageTheme extends Theme
{
protected $pThemeGridFrameworkHandle = 'bootstrap5';
public function getThemeName()
{
return t('SNF 2024');
}
public function getThemeDescription()
{
return t('Theme description comes here');
}
public function getThemeEditorClasses()
{
return [
['title' => t('Title Thin'), 'menuClass' => 'title-thin', 'spanClass' => 'title-thin', 'forceBlock' => 1],
['title' => t('Title Caps Bold'), 'menuClass' => 'title-caps-bold', 'spanClass' => 'title-caps-bold', 'forceBlock' => 1],
['title' => t('Title Caps'), 'menuClass' => 'title-caps', 'spanClass' => 'title-caps', 'forceBlock' => 1],
['title' => t('Image Caption'), 'menuClass' => 'image-caption', 'spanClass' => 'image-caption', 'forceBlock' => '-1'],
['title' => t('Standard Button'), 'menuClass' => '', 'spanClass' => 'btn btn-default', 'forceBlock' => '-1'],
['title' => t('Success Button'), 'menuClass' => '', 'spanClass' => 'btn btn-success', 'forceBlock' => '-1'],
['title' => t('Primary Button'), 'menuClass' => '', 'spanClass' => 'btn btn-primary', 'forceBlock' => '-1'],
];
}
}
You still have errors in your code. Here it is corrected:
<?php
namespace Application\Theme\Snf2024;
use Concrete\Core\Page\Theme\Theme;
use Concrete\Core\Area\Layout\Preset\Provider\ThemeProviderInterface;
class PageTheme extends Theme implements ThemeProviderInterface
{
protected $pThemeGridFrameworkHandle = 'bootstrap5';
public function getThemeName()
{
return t('SNF 2024');
}
public function getThemeDescription()
{
return t('Theme description comes here');
}
public function getThemeEditorClasses()
{
return [
['title' => t('Title Thin'), 'menuClass' => 'title-thin', 'spanClass' => 'title-thin', 'forceBlock' => 1],
['title' => t('Title Caps Bold'), 'menuClass' => 'title-caps-bold', 'spanClass' => 'title-caps-bold', 'forceBlock' => 1],
['title' => t('Title Caps'), 'menuClass' => 'title-caps', 'spanClass' => 'title-caps', 'forceBlock' => 1],
['title' => t('Image Caption'), 'menuClass' => 'image-caption', 'spanClass' => 'image-caption', 'forceBlock' => '-1'],
['title' => t('Standard Button'), 'menuClass' => '', 'spanClass' => 'btn btn-default', 'forceBlock' => '-1'],
['title' => t('Success Button'), 'menuClass' => '', 'spanClass' => 'btn btn-success', 'forceBlock' => '-1'],
['title' => t('Primary Button'), 'menuClass' => '', 'spanClass' => 'btn btn-primary', 'forceBlock' => '-1'],
];
}
}
at least another error 
Class Application\Theme\Snf2024\PageTheme contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Concrete\Core\Area\Layout\Preset\Provider\ThemeProviderInterface::getThemeAreaLayoutPresets)
There is one more function that is required even if you’re not going to use it. I didn’t include it hence the error.
It the last one I added, named getThemeAreaLayoutPresets.
I left stuff in it so you can see what it does and how it works.
<?php
namespace Application\Theme\Snf2024;
use Concrete\Core\Page\Theme\Theme;
use Concrete\Core\Area\Layout\Preset\Provider\ThemeProviderInterface;
class PageTheme extends Theme implements ThemeProviderInterface
{
protected $pThemeGridFrameworkHandle = 'bootstrap5';
public function getThemeName()
{
return t('SNF 2024');
}
public function getThemeDescription()
{
return t('Theme description comes here');
}
public function getThemeEditorClasses()
{
return [
['title' => t('Title Thin'), 'menuClass' => 'title-thin', 'spanClass' => 'title-thin', 'forceBlock' => 1],
['title' => t('Title Caps Bold'), 'menuClass' => 'title-caps-bold', 'spanClass' => 'title-caps-bold', 'forceBlock' => 1],
['title' => t('Title Caps'), 'menuClass' => 'title-caps', 'spanClass' => 'title-caps', 'forceBlock' => 1],
['title' => t('Image Caption'), 'menuClass' => 'image-caption', 'spanClass' => 'image-caption', 'forceBlock' => '-1'],
['title' => t('Standard Button'), 'menuClass' => '', 'spanClass' => 'btn btn-default', 'forceBlock' => '-1'],
['title' => t('Success Button'), 'menuClass' => '', 'spanClass' => 'btn btn-success', 'forceBlock' => '-1'],
['title' => t('Primary Button'), 'menuClass' => '', 'spanClass' => 'btn btn-primary', 'forceBlock' => '-1'],
];
}
/**
* @return array
*/
public function getThemeAreaLayoutPresets()
{
$presets = [
[
'handle' => 'left_sidebar',
'name' => 'Left Sidebar',
'container' => '<div class="row"></div>',
'columns' => [
'<div class="col-sm-4"></div>',

return $presets;
}
}
i thank you so much!
it works! 
much appreciated!
Good luck with your project

I am not sure if this is ironic 
No not ironic. I’m not a native English speaker so I know I give the wrong impression sometimes.
It’s a curse
