Blog Tags API

The Blog Tags API allows you to pull in Blog tags into different parts of the website.

Learn more about APIs.

For performance reasons tag posts are retrieved on demand. That means that they are only retrieved if you actually start to use them in your templates. You don't need to do anything special to load posts.

For example, the following code would load posts on demand.

{% for post in category.posts %}
{% endfor %}

But if you don't use category.posts in your template then posts will never be loaded, which helps to improve performance.

Minimum Tag

{{ _api.blog.tags.template('template-name') }}

Example Tags

Get 5 tags

{{ _api.blog.tags.template('template-name').limit(5) }}

Get 10 tags in random display order

{{ _api.blog.tags.template('template-name').limit(10).random('yes') }}

Get 10 tags ordered by their tag name

Typically tags are ordered according to the display order settings set in the app. You can override that setting. There are two ways to do sorting. One is to use a combination of the sortKey and sortDirection parameters. The other is to use the sort parameter.

{{ _api.blog.tags.template('template-name').limit(10).sortKey('tagName').sortDirection('asc') }}

{{ _api.blog.tags.template('template-name').limit(10).sort('tagName', 'asc') }}

Tag Parameters

ParameterDescription
allInstances Whether or not to query accross all instances of this app.

Type: String

Accepted Values:
'true', 'false', '1', '0', 'yes', 'no'

Example:
allInstances('yes')
attr List of attribute layout keys and the values that the filter should match.
If multiple values for an attribute need to be matched then you can separate them with a comma.

The first parameter is the attribute layout key.
The subsequent parameters are the value or values to match.

There are a few ways to pass values:

attr('layoutKey', 'value')

attr('layoutKey', 'value', 'value2', 'value3')

attr({'layoutKey': 'value'})

If you're trying to get app items by their ids and the ids are stored in an array then the following is the best way to get them.

attr({'id': myIds|join(',')})

If you're trying to get app items by their ids you can also sort them in the order that the ids are passed.

attr({'id': myIds|join(',')}).sort({'id': 'asc'})

Type: Hash

Examples:
attr('layoutKey', 'value')


Get items that match a list of item ids
attr({'id': myIds|join(',')})
first Limits the items returned to the first item.

It's the same as using limit(1)

Example:
first()
keys Comma separated list of layout keys that will be used to only return that data.

Type: String

Example:
keys('layoutKey1, layoutKey2')
id Limits the results to one or more app items that match the specified id.

This is an alternate option to passing the ids with the "attr" parameter like
.attr({id: 3})

You can pass a single app item id, multiple ids separated by a comma, or an array of ids.

.id(3)

.id(3, 4, 6, 10, 33)

.id([3, 4, 6, 10, 33])

Type: String

Accepted Values:
A single id value, multiple id values separated by a comma, or an array of ids.

Examples:
id(3)


id([3, 5, 7])
instanceKey
i
The key for the instance to get results in. If nothing is passed then the current instance will be used if this is called within the same app.

You can alternately use the short form "i" (lowercase I) instead of "instanceKey"

Type: String

Examples:
instanceKey('app-instance-key')


i('app-instance-key')
limit
l
The number of results to return. Defaults to return all matching results (no limit).

You can alternately use the short form "l" instead of "limit"

Type: Integer

Examples:
limit(5)


l(5)
match Whether or not to match all parameter conditions or any of the parameter conditions. Defaults to 'all'.

For example, if you passed multiple attribute values with the "attr" parameter then this would decide whether or not to only return items that match all of the attr values, or ones that match at least one of the attr values.

Type: String

Accepted Values:
'any' or 'all'

Example:
match('any')
random Sets the results to be returned in random order. If sorting is setup that will override this value.

Simply using the parameter turns random ordering on.

By default results are returned in an order based off of the app settings.

Type: String

Example:
random()
randomSelect Whether or not the results will be randomly selected from the database. This is done independantly of the sorting. This makes it possible to randomly select some data and then sort that random data by a specific column.

Type: String

Accepted Values:
'true', 'false', '1', '0', 'yes', 'no'

Example:
randomSelect('yes')
responseFormat Sets how the API response will be returned.

Type: String

Accepted Values:
template - The default value. This tells the system to use a Content Template to build the API response.
ui - This is used if the data from the API call will used in the administration as a UI form component. A Content Template will be used to structure the data correctly to build the form component HTML.

Example:
responseFormat('ui')
sort Sets the layout keys and the direction to sort by. If this is not used then sortDirection and sortKey will be used if they are set.

You can target a value beyond the first level of an array by using the "dot syntax". Example: myDate.timestamp will get the 'timestamp' value within the 'myDate' array.
array('myDate' => array('timestamp' => '1393657200', 'date' => 'March 1, 2014')).

The first parameter is the attribute layout key to sort by.
The second parameter is the direction to sort by.

You can set layout keys to sort by passing the parameter multiple times.
sort('layoutKey', 'asc').sort('anotherKey', 'desc')

If you're trying to get app items by their ids you can also sort them in the order that the ids are passed.

attr({'id': myIds|join(',')}).sort({'id': 'asc'})

Type: String

Accepted Values:
asc - Ascending order (A - Z or 1 - 10)
desc - Descending order (Z - A or 10 - 1)

Examples:
sort('layoutKey', 'asc')


Sort by a value beyond the first level of a multi-dimensional array
sort('myDate.timestamp', 'asc')
sortDirection The direction to sort. Allowed values are "asc" and "desc"

Type: String

Accepted Values:
asc - Ascending order (A - Z or 1 - 10)
desc - Descending order (Z - A or 10 - 1)

Example:
sortDirection('desc')
sortKey A single layout key to sort on. If you need to sort on multiple layout keys use the 'sort' parameter instead.

You can target a value beyond the first level of an array by using the "dot syntax". Example: myDate.timestamp will get the 'timestamp' value within the 'myDate' array.
array('myDate' => array('timestamp' => '1393657200', 'date' => 'March 1, 2014')).

Type: String

Examples:
sortKey('layoutKey')


Sort by a value beyond the first level of a multi-dimensional array
sortKey('myDate.timestamp')
startAt Where to start in the results. Defaults to 0.

Type: Integer

Example:
startAt(2)
template
t
Required if responseFormat is not 'data'. The template key of the template to use.

If this is not passed when it's required then nothing will be returned. In some cases, by not passing this parameter you will get just the raw data back.

You an alternately use the short form "t" instead of "template"

Type: String

Examples:
template('template-key')


t('template-key')
unique Specifies whether or not the result should have unique values. This is really only useful if one layout key is returned for each item.

Type: String

Accepted Values:
'true', 'false', '1', '0', 'yes', 'no'

Example:
unique('yes')
