Description

This script enables replacing of strings in pages, by creating special replace links or input forms.

Markup syntax for replace links:

Optional parameters:

• label="Replace": link text label

Replacements can also be done with Input forms, using action stringreplace.

Examples

Replace toggle link for page text variable Var

(:Var:0:) Page text variable {$:Var}

(:if eq {$:Var} 0:)(:stringreplace str1=":Var:0:" str2=":Var:1:" label="Toggle Var":)
(:if eq {$:Var} 1:)(:stringreplace str1=":Var:1:" str2=":Var:0:" label="Toggle Var":)
(:if:)

Dummy link: Toggle Var

Input radio buttons to change page text var State

'''state: {$:State}'''
(:input form "{$PageUrl}":)
(:input hidden action stringreplace:)
(:input hidden str1 ":State:{$:State}:":)
(:input radio str2 ":State:1:":) state 1 \\
(:input radio str2 ":State:2:":) state 2 \\
(:input radio str2 ":State:3:":) state 3 \\
(:input submit post Change:)
(:input end:)

Dummy form: state: 1

Notes

• The script allows replacements only on pages for which the user has edit authorisation.
• Replacing strings in target pages (using the target= parameter) is disallowed by default.
• The page is scanned line by line for the string to be replaced. Lines with the (:stringreplace ...:) markup or (:input ..:) markup are ignored.
