Hi,
You have a few options, in all options you have to modify FooterContent.php, and in some cases also FooterContent.ss.
The options:
1) Set the datatype of one of the datafields to HTMLText or HTMLVarchar(255) (fx address1 => Text, becomes address1 => Varchar(255) ), so you can add HTML to the address1-field. If you like you can also change the addressfield to HTMLEditorField or TextareaField (instead of TextField).
2) Add an Image datafield to the database:
class FooterContent extends Page{
...
static $has_one = array (
myimage => image
);
...
And now: read up on
ImageField, or
SimpleImageField. You might also want to read up on
images,
image uploading and
formfieldtypes for more advanced AND general information.
3) Create a new databasefield of the type HTMLText or HTMLVarchar(255). Create a new
TextareaField FieldType to be able add any HTMLblock to your footer.
If you created new datafields&formfields (as in 2 and 3), of course you also have to modify your template-file (.ss), otherwise the new info wouldn't show up.
Good luck
BTW maybe the person who set up your database already set some of those fields to HTMLText or HTMLVarchar. Just try it out...
