Profile Editor

Configure your editor as you need it.

Code Examples

Use in general:

Input Code

 <textarea class="form-control cke5-editor" data-profile="default" data-lang="<?php echo \Cke5\Utils\Cke5Lang::getUserLang(); ?>" name="REX_INPUT_VALUE[1]">REX_VALUE[1]</textarea>

Output Code

REX_VALUE[id="1" output="html"]

Further data attributes can be used to control the minimum and maximum height as well as the language:

• data-max-height
• data-min-height
• data-lang

Use in YForm

• individual attribute field: {"class":"cke5-editor","data-profile":"default","data-lang":"en"}
• further attributes possible separated by commas

Use in MForm

$mform = new MForm();
$mform->addTextAreaField(1, 
        array(
        'label'=>'Text',
        'class'=>'cke5-editor', 
        'data-lang'=>\Cke5\Utils\Cke5Lang::getUserLang(), 
        'data-profile'=>'default')
        );
echo $mform->show();

Use in MBlock

$id = 1;
$mform = new MForm();
$mform->addFieldset('Accordion');
$mform->addTextField("$id.0.titel", array('label'=>'Titel'));
$mform->addTextAreaField("$id.0.text", 
        array(
        'label'=>'Text',
        'class'=>'cke5-editor', 
        'data-lang'=>\Cke5\Utils\Cke5Lang::getUserLang(), 
        'data-profile'=>'default')
        );
echo MBlock::show($id, $mform->show());

Adding own fonts

To make the specified fonts visible in the backend, they must be loaded as assets in the backend. This can be done, for example, with the boot.php of Project AddOn or backend.css of Theme AddOn. The fonts should be defined in the usual CSS notation in the FontFamily section of the Profile Editor.

Customizing

The display of the editor can be adapted to the frontend output via CSS. For this a CSS file is available in the folder assets/addons/cke5_custom_data

CSS Content-Styles

CKE5 uses some own styles.

Link to Styleguide

The Styles are prefixed with .ck-content. You should add this class to your output element and load the included cke5_content_styles.css form the assets folder.

After installation of this AddOn you can use /assets/addons/cke5/cke5_content_styles.css or better make your own.

                "class": "ck-heading_heading1"
            }

        ]

}

Example for a custom link decorator

Attention, keys should be lowercase

[{
    "newtab": {
        "mode": "manual",
        "label": "Open in a new tab",
        "attributes": {
            "target": "_blank",
            "rel": "noopener noreferrer"
        }
    }
}]

[{
    "arrowclass": {
        "mode": "manual",
        "label": "Link mit CSS Klasse",
        "defaultValue": "true",
         "attributes": {
            "class": "button light",
        }
    }
}]

Multiple link decorators

[
    {
        "buttonlink": {
            "mode": "manual",
            "label": "Als Button darstellen",
            "attributes": {
                "class": "uk-button uk-button-primary uk-margin-small-bottom"
            }
        },
        "buttonlink_style": {
            "mode": "manual",
            "label": "Link mobil volle Breite",
            "attributes": {
                "class": "uk-width-1-1@s uk-width-auto@m"
            }
        }
    }
]

YForm links

To replace the generated urls like rex_news://1, the following script must be added to the boot.php of the project AddOn. This would require the code for the urls to be modified.

rex_extension::register('OUTPUT_FILTER', function(\rex_extension_point $ep) {
    return preg_replace_callback(
        '@((rex_news|rex_person))://(\d+)(?:-(\d+))?/?@i',
        function ($matches) {
            // table = $matches[1]
            // id = $matches[3]
            $url = '';
            switch ($matches[1]) {
                case 'news':
                    // Example, if the Urls are generated via Url-AddOn  
                    $id = $matches[3];
                    if ($id) {
                       return rex_getUrl('', '', ['news' => $id]); 
                    }
                    break;
                case 'person':
                    // ein anderes Beispiel 
                    $url = '/index.php?person='.$matches[3];
                    break;
            }
            return $url;
        },
        $ep->getSubject()
    );
}, rex_extension::NORMAL);

Profile API

By using the API: Cke5\Creator\Cke5ProfilesApi::addProfile, it is possible to install own profiles beside of the profile editor.

Example:

    $create = \Cke5\Creator\Cke5ProfilesApi::addProfile(
        'profile_name_cke5',
        'API created Cke5 profile',
        '{
           "toolbar": ["link", "rexImage", "|", "undo", "redo", "|", "selectAll", "insertTable", "code", "codeBlock"],
           "removePlugins": ["Alignment", "Font", "FontFamily", "MediaEmbed", "Bold", "Italic", "BlockQuote", "Heading", "Alignment", "Highlight", "Strikethrough", "Underline", "Subscript", "Superscript", "Emoji", "RemoveFormat", "TodoList", "HorizontalLine", "PageBreak"],
           "link": {"rexlink": ["internal", "media"]},
           "image": {
             "toolbar": ["imageTextAlternative", "|", "imageStyle:full", "imageStyle:alignLeft", "imageStyle:alignRight", "imageStyle:alignCenter"],
             "styles": ["full", "alignLeft", "alignRight", "alignCenter"]
           },
           "table": {"toolbar": ["tableColumn", "tableRow", "mergeTableCells", "tableProperties", "tableCellProperties"]},
           "rexImage": {"media_path": "\/media\/"},
           "ckfinder": {"uploadUrl": ".\/index.php?cke5upload=1&media_path=media"},
           "placeholder_en": "Placeholder EN",
           "placeholder_de": "Placeholder DE",
           "codeBlock": {
             "languages": [{"language": "plaintext", "label": "Plain text", "class": ""}, {
               "language": "php",
               "label": "PHP",
               "class": "php-code"
             }]
           }
         }',
        '[{"min-height": 100}, {"max-height": 280}]'
    );
    echo (is_string($create)) ? $create : 'successful profile created';
