Data Types
These are the data-types that you can use when defining your data objects. They are all subclasses of [api:DBField]
for introducing their usage.
Types
[api:Varchar]
: A variable-length string of up to 255 characters, designed to store raw text[api:Text]
: A variable-length string of up to 2 megabytes, designed to store raw text[api:HTMLVarchar]
: A variable-length string of up to 255 characters, designed to store HTML[api:HTMLText]
: A variable-length string of up to 2 megabytes, designed to store HTML[api:Enum]
: An enumeration of a set of strings[api:Boolean]
: A boolean field.[api:Int]
: An integer field.[api:Decimal]
: A decimal number.[api:Currency]
: A number with 2 decimal points of precision, designed to store currency values.[api:Percentage]
: A decimal number between 0 and 1 that represents a percentage.[api:Date]
: A date field[api:SS_Datetime]
: A date / time field[api:Time]
: A time field
HTMLText vs. Text, and HTMLVarchar vs. Varchar
The database field types [api:HTMLVarchar]
and [api:Varchar]
are exactly the same in the database. However, the
templating engine knows to escape the [api:Varchar]
field and not the [api:HTMLVarchar]
field. So, it's important you
use the right field if you don't want to be putting $FieldType.XML everywhere.
If you're going to put HTML content into the field, please use the field type with the HTML prefix. Otherwise, you're going to risk double-escaping your data, forgetting to escape your data, and generally creating a confusing situation.
Usage
