How can I add delete links or buttons with which to delete lines or sections?
Description
An add-on for the Fox form processor which enables line or section delete links and buttons.
Install in the usual manner by copying to cookbook/ or cookbook/fox/ folder and including in local config file.
This script adds template markup {[foxdelline]}, {[foxdelrange]}, {[foxdelline button]} and {[foxdelrange button]} which can be used in a Fox template to create a delete link or button to delete a line or posted content section.
Note that the markup is for fox templates only! The delete link or button form gets created via a Fox posting. Thereby Fox adds an id number to the link and button, which makes it possible to target the line or section for
deletion in which the link or button is situated. Sections are marked by using and markers in the template.
Examples
The following will add a line of input text with a foxdelete (line) link for line deletion above the foxappend marker, thereby following additions are added below previous ones (use (:foxprepend frm:) to achieve the opposite, i.e. latest on top):
(:fox frm1 :)
(:foxtemplate "* {$$comment} {[foxdelline]}":)
(:input text comment size=50:)
(:input submit post 'Add Comment':)
(:foxend frm1:)
(:foxappend frm1:)
The following will add a section of text to the page, with a foxdelete (range) link for deleting the whole section:
(:fox frm2 template=commenttmpl:)
(:input textarea comment rows=6 cols=50:)
(:input submit post 'Add Comment':)
(:foxend frm2:)
(:if false:)
[[#commenttmpl]]
#foxbegin#
----
%rfloat%{[foxdelrange]}
{$$comment}
#foxend#
[[#commenttmplend]]
(:if:)
Note the template uses and markers for identifying the delete range.
The template here is defined on the same page, but can be equally or better defined on a separate template page, like Site.FoxTemplates. (:if false:)...(:if:) is used to suppress the template from being shown in the page.
Notes
The foxdelete markup and action handling function was previously included in fox.php.
