Documentation

pageTitle :: (?context :: ControllerContext) => Text Source #

Returns the current page title. The title can be set using setTitle "my title" from the action.

If the title hasn't been set yet, this will return an empty string. You can also use pageTitleOrDefault to pass a custom default title.

You can use this inside your title tag like this:

[hsx|
    <head>
        <title>{pageTitle}</title>
    </head>
|]
  • App-wide default title:*

You can set a app-wide default title by calling setTitle from the FrontController.hs:

instance InitControllerContext Web where
    initContext = do
        setLayout defaultLayout
        initAutoRefresh
        setTitle "Jobs"
  • View-specific title:*

You can set a custom title inside the view by calling setTitle inside the beforeRender hook.

module JobSite.View.JobPositions.Show where

instance View ShowView where
    beforeRender ShowView { .. } = do
        setTitle "Custom title"

    html ShowView { .. } = [hsx|..|]

pageTitleOrDefault :: (?context :: ControllerContext) => Text -> Text Source #

Returns the current page title, like pageTitle but returns a provided default value instead of an empty string if no title is set.

You can use this inside your title tag like this:

[hsx|
    <head>
        <title>{pageTitleOrDefault "My Application"}</title>
    </head>
|]

pageTitleOrNothing :: (?context :: ControllerContext) => Maybe Text Source #

Returns the current page title or Nothing if not set yet

module IHP.PageTitle.ControllerFunctions

Re-export as we want to call setTitle from the beforeRender hook
