=== Graceful Pull-Quotes === Contributors: strider72 Donate link: https://paypal.me/SteveRider Tags: theme, pull-quotes, pull quotes, blurb, quotation, quote Requires at least: 2.6 Tested up to: 4.5.1 Stable tag: 2.6.1 Allows you to make pull-quotes without duplicating content. If the plugin is disabled the pull-quotes disappear seamlessly. == Description == This plugin allows you to make pull-quotes ( http://en.wikipedia.org/wiki/Pull-quote ) in your posts without duplicating any content. Text you select will be duplicated as a pull-quote. This is done entirely via JavaScript and is designed to seamlessly vanish if the plugin is disabled later. Using JavaScript instead of PHP also ensures that duplicate content doesn't show up in your feeds. It is named for the fact that it degrades gracefully in browsers that can't handle the JavaScript, as well as not leaving behind visible cruft (such as shortcodes) if the plugin is later deactivated. This plugin was previously known as "JavaScript Pull-Quotes" == Installation == Upload the ENTIRE folder to your plugins folder (`/wp-content/plugins/`) while keeping the file structure intact. You've done it right if you end up with a folder called "graceful-pull-quotes" inside your "plugins" folder. Then activate it on your plugin management page. Finally, go to the Pull-Quotes settings panel, (under the "Appearance" tab), and select your options. This step is optional, as the program works pretty well right out of the box, but you might want to at least previewing the different quote styles. == Usage == NOTE: If you would like to have a "Pull-quotes" button in the post editor, I highly recommend Frank Bueltge's Add Quicktags plugin. I've included in my plugin (in the "extras" folder) a settings file that you can import into "Add Quicktags" (though it isn't hard to do it manually). To make a pull-quote: 1. Just wrap the text you want to put in a pull-quote like this: All you need to do is ``wrap the quotable text in a span element and give it the class name "pullquote"``. The won't affect how that text shows up, but it tells the JavaScript to _duplicate_ it as a pull-quote. 2. (optional) If you want a pull-quote that has text *different* than the text in the ``, put it inside `` like so: ``This sentence, without this middle clause, should be a pull-quote``. The content inside the HTML comment will *only* show up as the pull-quote -- it will not appear at all in the main flow of text. 3. (optional) To specify a side for a particular pull-quote, give the ` a secondary class of either pqLeft or pqRight (that's case-sensitive!), like so: ``This will appear on the right` no matter what the Settings screen says. == Bugs and Workarounds == = Note Regarding HTML Comments = A little known "gotcha" with HTML quotes is that technically speaking you are not allowed to put a double-dash ("--") inside a comment, except as part of the beginning and end markers. (A double-dash technically ends an HTML comment.) In some browsers I have seen this expose comment data as page text. This is part of the official HTML spec and not a "bug" per se in this plugin. BUG: WordPress does weird things if you try to put HTML tags inside an HTML comment. See http://core.trac.wordpress.org/ticket/8912 for more info. This may be fixed in WP 3.3. BUG: HTML entities (e.g. accented characters) inside HTML comments get messed up. I believe this is a WordPress bug related to the above bug. = Workaround Regarding Buggy Browsers = There is a bug in the JavaScript rendering of certain less common browsers (including very old versions of Safari) which causes it to misfire on the alternate text. Assuming that some of your readers may use these browsers, you have two options: A) Do the alternate text as described. Affected browsers will show the *actual* text in the span as though the alternate were not there. B) Put the comment alone in a pullquote span, just _before_ the sentence you're (sort of) quoting. Affected browsers will not show any pull-quote, but other browsers will work normally. Example: ``Darn that JavaScript-mangling browser! == History == I've been using WordPress for years now. In late 2006 I was reading through the excellent book "DOM Scripting", by Jeremy Keith, which teaches how to use JavaScript to manipulate the structure of (X)HTML documents. As I read through, learning how to move, duplicate, and change parts of a web page with scripts, I came up with the concept that it could be used to make pull-quotes programmatically. The CSS required to do pull-quotes is easy, but I didn't like the idea of having text duplicated in the HTML for what is ultimately a purely visual effect, so the idea of doing it with JavaScript appealed to me -- it created the entire pull-quote from whole cloth and disappeared entirely if the JavaScript didn't run for some reason. (That is, it "degrades gracefully" in less capable browsers.) Entirely by coincidence, blogger Jeffery Harrell, right about that time, pointed me to a script written by Roger Johanssen . We weren't even discussing my idea at the time -- it was simply a "hey, this is neat" post on Jeff's blog. So I took a look. As it turns out, Roger basically had created _exactly_ the script I had had in mind -- right down to a limitation mine would have had because I (and he) didn't know how to code around it. Before I even saw his script, a commenter on his blog had fixed that limitation, and a second commenter had gone and tucked it into a "wrapper" that made it into a WordPress plugin. No frills, no fuss -- it simply applied the script to WordPress pages. (You can find that version here: http://www.viper007bond.com/wordpress-plugins/javascript-pullquotes/ ). Finally, I (Stephen Rider) picked it up and started adding features, including the options panel and all user changeable options, alternate text quotes, styles, localization compatibility, and pretty much everything beyond the simple script link. I've put a lot of hours into this plugin, and have learned a lot about JavaScript, PHP, and WordPress along the way. Enjoy! --Stephen Rider == Changelog == = 2.6.1 (15 April 2015) = * Switched links default back to "head" = 2.6 (15 April 2015) = * Added Setting to put the Style and Script links in the page footer, and set "footer" to default * Updated hook for Settings link on Plugins page * Updated PHP4-style constructor function * Moved a bit of JavaScript into linked file * Minor code cleanup = 2.5 (17 February 2015) = * Added "aside" to options for HTML container, and set that to default for new installs * Reworked how the Default Style backup works if Styles folder is not found * Improved compatibility with upcoming translation features of WordPress * Now using some built-in WP abstractions: trailingslashit(), selected(), and checked() * Code cleanup = 2.4.2 (27 November 2012) = * Pull-quote text in an HTML comment is now trimmed of spaces * Improved testing for empty pull-quotes before rendering * Bugfix: Was not saving container setting correctly -- error in HTML rendering on Settings page = 2.4.1 (3 September 2011) = * A jspullquotes.css file in a theme is now properly detected in both Parent and Child themes = 2.4 (5 May 2011) = * Updated filenames to reflect new plugin name. * Updated .po localization files to reflect current code (calling all translators!) * A few more tweaks in preparation for adding plugin to the Official WP Extend repository = 2.3 (28 March 2010) = * Renamed to "Graceful Pull-Quotes" (formerly "JavaScript Pull-Quotes") * New Persian translation * Added Style headers to Pull-Quote style files (prep for upcoming feature) * Fixed bug in Settings page for selecting default side (Thanks Sébastien!) * Fixed array bug in internal get_plugin_data * In core CSS, fixed background colors and text colors to inherit from parent * Updated Settings page CSS for WP 2.6/2.7 -- Save Changes button is "primary" color * JavaScript variable in wp-head now has less stompable name * Admin head now uses `wp_enqueue_script()` for preview script * Fixed path constant in `add_ozh_adminmenu_icon` function * Translations folder renamed to "lang" = 2.2 (25 September 2008) = * Changed how Default style works -- "Default.css" is again in the styles folder. If for any reason the program can't find _any_ styles, it falls back to a _copy_ of Default.css in the resources folder. This way people aren't forced to have Default on the list. * New German translation (Dank Mattias!) * Updated .po files * Added Ozh Drop Down Menu icon * code changes: `plugin_path => plugin_dir` | `pq__() => p__()` | `pq_e() => p_e()` = 2.1.2 (23 July 2008) = * Fixed design flaw introduced in 2.1.1.

Now runs on "init" hook instead of running blind on plugin inclusion. * Moved textdomain load and `$plugin_path` define into `init()` * Unchecked boolean options are now explicitly set to false * `set_defaults()` will now merge defaults with existing settings -- i.e. fill in new or missing options in a newly upgraded install * Added `compare_versions()` -- Auto-run set_defaults on update without reactivate * Changed `option_name` in `wp_options` table. Now "`plugin_jspullquotes_settings`" - Will automatically transfer from old to new * Uses "Ozh method" to attach footer to Settings page (Call is in `settings_page()` instead of `init()` ) * Added static to `get_plugin_data()` -- no need to read the file twice * BUGFIX: Moved `register_activation_hook` outside of class. In `init()` it was never being called = 2.0 (8 June 2008) = * Rewrote Settings page to WP 2.5 standard * New Setting: strip internal links "href='#id'" from pull-quote * Added "Settings" link to Actions on Plugins screen * Strips "a" tags that lack "href" attribute from pull-quote * Strips "id" and "name" attributes from tags in pull-quote * Moved home page link on Settings page to page footer * Improved error correction if Style files go missing (not finished though) * BUGFIX: Files starting with "." should not appear in styles list in Admin * Misc. code clean & polish = 1.7.0 (6 June 2008) = * BUGFIX: "preview" script is now only added to Pull-Quotes page -- used to add to ever admin page (was causing problems when editing posts) * Improved security via nonces. See: http://markjaquith.wordpress.com/2006/06/02/wordpress-203-nonces/ * Changed name of preview script in Admin to avoid potential conflicts * Removed "edit CSS" link from Admin. Doesn't work in WP 2.5 * Simplified HTML comments on page headers. Blog pages no longer have plugin URL and Admin page no longer has version. * Extensive code cleanup and abstraction -- e.g. function calls now use "$this->" when possible. Also, new class functions: - `__()` - `_e()` - `get_plugin_data()` * Eliminated separate "class" file * Consolidated `set/reset_defaults()` functions * Some documentation cleanup = 1.6.7 (15 January 2008) = * NEW French localization — Merci Ben! * BUGFIX - version display in page header was broken * Small fix to options page localization * minor code changes = 1.6.6 (26 November 2007) = * Added User Option to _not_ link CSS — this way admin can put CSS in site’s main CSS file and save some HTTP requests * Plugin path now uses plugin_basename() (stability improvement) * BUGFIX - version display on Options screen was broken = 1.6.5 (31 August 2007) = * added function to set defaults if no options are set * reorganized files in jspullquotes directory * added JSPQPATH constant to make paths less brittle * changed User Capability requirement to "switch_themes" * test for both "switch_themes" and "edit_themes" capabilities before writing "edit stylesheet" box to admin screen * changed name of class, for filename consistency = 1.6 (25 July 2007) = * Italian localization added * Changed user requirement for Options Screen. Was Access Level “7″, now requires Capability "`edit_themes`" * Minor experimental change that may or may not kick in in a future update of WordPress (yes, I like keeping you in suspense! :) ) [Update: Won't happen. It was the "settings" link in the header, which I thought I could get implemented in WP. Removed in plugin v1.7] = 1.5.4 (16 June 2007) = * The preparations for localizations are complete. A POT file is now included with the download. Please send me translations and I will include them with the download! :) * Cleaned up the identification comments included in the page additions * Some code cleanup and rearrangement.
