Assetylene, a plugin for Movable Type
This plugin provides a new "Caption" field when inserting an asset into a post, and the ability to customize the HTML markup produced for publishing MT assets.
Note that Assetylene 2.0.0 is very different from 1.x, to work with Movable Type 6.2.2 and later. If upgrading, your Asset Insertion Template Module will need to be updated to work with Assetylene.
- Movable Type 6.2 or later
- Movable Type 4.2 or later, 5.x, 6.0.x, and 6.1.x are supported with version 1.1.1 of Assetylene.
To install this plugin follow the instructions found here:
This plugin adds a "Caption" checkbox and field to the asset Insert Options dialog. The caption field can of course be edited, but is pre-populated with the value of the asset's Description field. Note that selecting the "Caption" checkbox enabled/disabled display of the caption; the text doesn't need to be deleted from the caption field if you don't want it displayed.
After creating the Asset Insertion Template Module and customizing it as necessary, no further interaction from the author is necessary to use the new template during the asset insert process.
Template and Template Tags
Create a Template Module named "Asset Insertion", and that template will then be used to create the HTML for any asset you embed into a post.
Assetylene adds a number of template tags that can be used in the Asset Insertion Template Module. These tags reflect options that are set on the asset Insert Options screen.
mt:AssetyleneAlign: The value of the "Alignment" field, either
mt:AssetyleneCaption: The value of the caption field, if the "Insert a caption?" checkbox is selected.
mt:AssetyleneEnclose: This value is used to track whether the asset inserter is being used with an Asset Custom Field. If a Custom Field is being used then this value is true, otherwise false.
mt:AssetyleneInclude: This value is true if the "Display Image in entry/page" checkbox is selected; false otherwise.
mt:AssetyleneNewEntry: This value is true if the asset is being inserted into a new and unsaved Entry or Page, otherwise false.
mt:AssetylenePopup: This value is true if the "Link image to full-size version in a popup window" checkbox is selected; false otherwise.
mt:AssetyleneThumb: This value is true if the "Use thumbnail" checkbox is selected; false otherwise.
mt:AssetyleneThumbWidth: This is the "width: [ ] pixels" value for the thumbnail.
mt:AssetyleneWrapText: This value is always true.
Assetylene provides one more tag:
mt:AssetyleneDefaultHTML. This tag uses the
above tag values to build the default HTML created by Movable Type.
Additionally, the Asset Insertion Template Module should use the Assets block tag to enter asset context of the assets selected for inserting. The example template shows this in use:
<div class="assets"> <mt:Assets><mt:Section strip_linefeeds="1" replace=" ",""> <mt:If tag="AssetyleneCaption"> <div class="caption align-<mt:AssetyleneAlign>"> <mt:If tag="AssetyleneThumb"> <mt:AssetyleneThumbWidth setvar="thumb_width"> <img src="<mt:AssetThumbnailURL width="$thumb_width">" alt="<mt:AssetLabel>" /> <mt:Else> <img src="<mt:AssetURL>" alt="<mt:AssetLabel>" /> </mt:If> <div><mt:AssetyleneCaption></div> </div> <mt:Else> <mt:AssetyleneDefaultHTML> </mt:If> </mt:Section> </mt:Assets></div>
Note the use of the
Section tag and arguments, and the different spacing of
Section, and closing
div.assets tags. All of this is to
format the inserted HTML, minimizing space used but still somewhat maintaining
