Questions, Comments and Discussion about ShowHide

• is it normal that ShowHide page isn't working at all, showing bunch of preg_replace() errors?

in case someone want download something, here is the link showhide.phpΔ --BlacK? June 03, 2018, at 06:19 PM

Thanks, I fixed it now and made the updated scripts available for download, but you probably should get Toggle instead. (After a recent migration some pages may need to be updated, we simply didn't notice this one.) --Petko June 03, 2018, at 06:54 PM

• Concerning the question below; I've gone with the include scripting below it. All that is needed is to read-password-protect the included page using the password utility of that page. I've left the question for the manager to delete, since it still would be great to be able to include password scripts with show-hide, and perhaps other recipes. Thanks, Jagtig

• Is it possible to include a password protect script such as Zubrag's or PhpBuddy so that the show hide brings up a user-password text box?

Wouldn't it be great to place material that you want to be handy for development behind show-hide buttons? You could then open it once, and it would be available for use as long as the password protect cookie was on your computer. However, visitors could not see what was there. Thanks a million.

• I'm using this in my page:

(:toggle div=box1:)
>>id=box1<< 
(:include groupname/pagename#from#to:)
>><<

Which works well to show the included page - provided the included page does not include markup for the WikiStylesPlus recipe. If the included page has markup such as

>>tip<<
Take regular breaks to avoid eye-strain
>><<

Then the Show/Hide toggle only works until it reaches the WikiStylePlus markup - after which the included text is displayed - even though the toggle is set to hide.

I'm not sure if this a Show/Hide feature, or WikiStyles or the "include" recipe that is causing this. I did try taking out the "offending" WikiStylePlus markup, but as I can't control another author putting such markup inthe page again later - I amlooking for a more robust solution. Any ideas?

HansB: It seems that the div markup of the included page closes the div of the toggle box div. Try to give the toggle div a "special identity" which allows nesting, like this (the numeric value after 'div' is not importent, but it must be matched in the ending markup, it is not a HTML id:

(:toggle div=box1:)
(:div0 id=box1:) 
(:include groupname/pagename#from#to:)
(:div0 end:)

• corrected above to put space between 0 and end in "div0end"; also in experimenting found what most may know: divLT is not valid (chars) div1010031820 is, i.e. must be numbers. Ward Christensen October 03, 2010, at 06:22 PM
• I've noticed that when an anchor has the same name as a div toggling fails - RandyB February 21, 2009 at 2:48 AM

• Question mark bug: This is a very useful recipe, but when you click on the next sentence, the special character turns into a question mark. Is that right?▼

• DaveG When I click the link, I alternate between up and down arrows. Can you confirm that it still doesn't work for you?
• RandyB? I confirm that it doesn't work for me, even though we are using the same server. Could it make a difference whether the client machine is a PC versus Mac?
• DaveG Could be. I'm on a PC. It's obviously related to the font. Does whatever font the Mac is using support fully Unicode? On the PC that label is represented using Arial. This page might help work out [(approve links) edit diff], and this [(approve links) edit diff].

• Escaping an apostrophe: An apostrophe breaks the label code. For example "It's not a valid label" doesn't work. Is there a way to get around that? -- RandyB January 28, 2009, at 8:01 PM
  • DaveG: Try a backslash before the quote. "It\'s not a valid label"
  • RandyB?: I tried that. Here's such a label: It\'s not working

• DaveG: Looks like a bug. I couldn't find a work-around, so I'll post a fix in a few days.
• Now fixed. - HansB February 16, 2009, at 01:33 PM
• It's still not working on my machine. The new version shows the apostrophe at first, but changes it to an odd character when I go from hide to show state, and thereafter the apostrophe becomes a question mark regardless of state. I'm using a Mac. - RandyB February 16, 2009
  • I try to investigate further. It has so far been quite difficult for me to find a way to pass special characters from php to javascript to HTML.

• Print view: Is there a way we could use the print template/skin so that all of the elements being hidden with this recipe could be shown? Like a global switch to show everything regardless of the options in the markup? This would be really useful when printing something out. --lordmundi May 25, 2007, at 01:09 PM

• Naming a div id. Watch out for Uppercase characters. If your first character is uppercase, then all the rest must be in lowercase (Abc). Additional capitals (ABc and AbC) will cause the markup to fail. If your first character is lowercase, however, then you can have multiple uppercase characters (aBC). --Pico
• Buttons. The show and hide buttons look really nice. For some purposes, however, it would be even better if we had an option that allowed a directory tree style of toggled buttons that can appear on the same line with some text (or the labelname).

• Default Parameters. It would be nice if we could set the default parameters so that each markup did not have to restate them.--Pico
  • Note, I was thinking about the markup for the toggle button (and link), but for the division, wikistyles will work fine. What I was looking for was something like wikistyle that could be used for the non-division markup (the toggle button and link). Pico

• Sidebar. I thought this would make a good new version of Expanding Menus, but for some reason this recipe doesn't seem to work when the button doesn't appear in the main part of the page... any idea why that might be the case? What's very strange is if you put one of these in Site/SideBar, you can toggle it when you are browsing that page, but as soon as you go to any other page, it doesn't work. Does this make sense? JonHaupt

• I'd like to be able to change the colour of a (:toggle:). Adding a wikistyle only works for the first display of the link. Best, for me, would be a CSS class for the text, since using .wikilink is inappropriate. Marc 5 Jun 06

span.toggle a:link {color:red; 
		text-decoration:none; 
		background:yellow;
		padding:3px;
		border:1px solid #999; }
span.toggle a:hover {color:blue; 
		background:#def; }

• Including togglelink.php leads to invalid XHTML. Check on http://validator.w3.org It complains about lines 89 and 98 where something seems to be wrong with
  copy='<a class="wikilink" ';

  The easiest way around this is probably to move the javascript code into a separate file, since it's the javascript that's tripping the validator up. It'd be cleaner that way anyway. - JonHaupt

• I copy pasted the sample code from this page into an empty wiki but nothing happens when I click the button (IE and FF). both php files are copied in the cookbook directory and have the correct rights assigned. Any idea? (or anything I can check?) Tnx! DJ jul-20-2007.

• Does the toggle (with text, no buttons) support nesting as well? When I tried it I couldn't get the main link to close the whole 'tree' when some of the sub-sections were opened. Another thing I run into is that with the non-button toggles I cannot keep a sub-section inside the main sections box, it will create a new box below. The button toggle automatically seems to do this correctly. (It would be great if someone has a code sample) Tnx! DJ Jul-20-2007.

• Would it be possible to have different colors for the different levels? (in the example if it had toggles instead of buttons: display 'show divisions' in gray and all other links in underline/blue? (small example?) with the span.toggle a: * you can only modify the looks of all links. 05.08.2007
• Is there any way
  • to show a division if the user follows a link to a point inside it?
  • to show all sections (or generally, more than one section) with one click?
  Thanks. This is a really useful cookbook. / WRF 23 Oct 2007

Why does the recipe use id, rather than class? I'd like to hide and show more than two things on a page?

I really appreciate this recipe and use it extensively. I'm trying using it in a sidebar, and each time the page changes the divs in the sidebar resume their default settings. Is there any way of preserving the state of the show hide divs in the sidebar, thanks Simon

• 21-Nov-2007: You should be able to add set=1; to config.php, which will remember the state of the div.

3-Jun-2008: I have been trying to get this to work on our build, but am not having much luck. The javascript function is not getting loaded in the header of our Wiki, and as a result, I get a javascript error: "showHide not defined". I have reviewed our pmwiki.tmpl file, as suggested in the Upgrade section above, but this was no help either. Can anyone offer any other advice? Thanks Adam

The skin tmpl file needs a <!--HTMLFooter--> markup near the end above the </body> tag. If you got this, examine the HTML page source. The javascript function should now be in the HTML page source near the bottom, if the wiki page contains one or more (:showhide ...:) markups. - HansB June 04, 2008, at 09:00 AM

• Hans - this resolved the issue. I had updated the non-skin template, but neglected to change the file specific to our skin. Thanks very much for your speedy response! Adam June 04, 2008, at 10:34 AM
• 23-Jun-2008 : For toggle with an image (not with a text)
  I add the code <img src=url /> (without ") in lshow and lhide, but I had to modify the code to add the function htmlspecialchars_decode

   if($tog=='show') { 
     $label = htmlspecialchars_decode($opt['lhide']);
     $tog = 'hide';
   } 
   elseif($tog=='hide') {
     $label = htmlspecialchars_decode($opt['lshow']);
     $tog = 'show';
   } 

So it works fine
