Add field to tt_content

To add the coordinates element to a CType, you have to add this to the tt_content.php:

1. Create a new column

To display the coordinates element you have to create a new column of your tt_content.php. Your tt_content.php could look like this, for example:

$GLOBALS['TCA']['tt_content']['columns']['tx_csimagepoint_coordinates'] = [
    'label' => 'LLL:EXT:cs_image_point/Resources/Private/Language/locallang.xlf:tx_csimagepoint_coordinates.label',
    'description' => 'LLL:EXT:cs_image_point/Resources/Private/Language/locallang.xlf:tx_csimagepoint_coordinates.description',
    'config' => [
        'type' => 'user',
        'renderType' => 'imagePointField',
        'parameters' => [
            'imageFieldName' => 'image',
            'isInlineRecord' => 'true'
        ],
    ],
];

Important: Make sure you have previously added the new table under Admin Tools > Maintenance.

Parameters

• imageFieldName: Specify the name of the element from which the image is taken
• isImageInParentRecord: True if the current element is an inline record and the image field is placed by parent, e.g. multiple tooltips.

2. Add the new column to your types

To display the coordinates element you have to add it to the types of your tt_content.php. Your tt_content.php could look like this, for example:

    $GLOBALS['TCA']['tt_content']['types']['tx_csimagepoint'] = [
    'showitem' => '
        --div--;Tab, --palette--;;general, image, tx_csimagepoint_coordinates',
];

Important: Your type must contain an image field.

3. Flush all caches

The last step: Clear the cache so that the TCA change takes effect.
