Topic: Images

0. How to use images in a slice ?
1. How can I include photos to the texts of articles?
2. How can I manipulate images (e.g. create thumbnails)

Using this method, you can, in the "add item" form, use an image from an existing URL or upload an image to use it.

1) in the ActionApps main menu, choose "Slice Admin" option
2) In the list of fields, there will be a field called "Image URL"
3) Edit the properties of the field...
a. Change input type to "File Upload"
b. Edit the parameter to "image/*"
c. Set Validate to "URL"
d. Set Insert to "File"

4) Now, you can use the alias _#IMAGESRC like :

This can be done thanks to function f_y - expanded string.

  1. In the slice "Photogallery" make a view or views, which will show a single photograph.
  2. It is usefull to define the aliases in the Slice Admin / Design / Item Manager, so in the Item Manager you will see below any photograph the alias or aliases for showing it, e.g.: "{view.php3?vid=1047&cmd[1047]=i-1047-6341bce1bd2d5072f75cc440d6e1edf4}"
  3. In the slice "Articles", for the field "full_text......." create an alias e.g. _#FULLTEXT with fuction "f_y" and with no defined parameters.
  4. During the editing of items you can just copy the aliases from the slice "photograph" to the places in the text, where you would like to have the photographs

See an example.
