Formfields
Formfields are the hearth of Voyagers BREAD-system. Each formfield represents a field in your database-table and one input (or output) in BREAD. To tweak your formfields you can insert JSON options which are described in the following pages.
All formfields share a handful options:
Description
All types can include a description in order to help your future self or other users using your Voyager admin panel to understand exactly what a specific BREAD input field is for, this can be defined in the Optional Details
JSON input field:
{
"description": "A helpful description text here for your future self."
}
Display options
There are also a few options that you can include to change the way your BREAD is displayed. You can add a display
key to your json object and change the width of the particular field and even specify a custom ID.
{
"display": {
"width": "3",
"id": "custom_id"
}
}
The width is displayed on a 12-grid system. Setting it with a width of 3 will span 25% of the width.
The id will let you specify a custom id wrapper around your element. example:
<div id="custom_id">
<!-- Your field element -->
</div>
Default value
Most formfields allow you to define a default value when adding an entry:
{
"default" : "Default text"
}
Null Values
You might want to save an input field into the database as a null
value instead of an empty string.
Simply enough, inside the BREAD you can include the following Optional Details for the field:
{
"null": ""
}
This will turn an empty string into a null
value. However you might want to be able to add both an empty string and a null
value to the database for that field. However you have to choose a replacement for the null
value, but it can be anything you wish. For example, if you want a field to change a string (ex. Nothing
) into a null
value you could include the following Optional Details for that field:
{
"null": "Nothing"
}
Now entering Nothing
into the field will end up as a null
value in the database.
Generating Slugs
Using the bread builder you may wish to automatically generate slugs of a certain input. Lets say you have some posts, which have a title and a slug. If you want to automatically generate the slug from the title attribute, you may include the following Optional Details:
{
"slugify": {
"origin": "title",
"forceUpdate": true
}
}
This will automatically generate the slug from the input of the title
field. If a slug does already exists, it will only be updated if forceUpdate
is set enabled, by default this is disabled.
Custom view
You can specify a custom view to be used for a formfield.
To do so, you have to specify the view
attribute for your desired field:
{
"view": "my_view"
}
This will then load my_view
from resources/views
instead of the formfield.
You get plenty of data passed to your view for you to use:
$action
can bebrowse
,read
,edit
,add
ororder
$content
the content for this field$dataType
the DataType$dataTypeContent
the whole model-instance$row
the DataRow
