RandomQuote-OldVersion

Goal

Insert a random quote into a wiki page.

Solution

randomquote.zipΔ

randomquote.zip unpacks into cookbook/quote.php.

add the following line to config.php

include_once("$farmD/cookbook/quote.php");

If your site doesn't use wikifarms, the correct include statement is

include_once('cookbook/quote.php');

(Note: I had trouble getting this script to work until I deleted the Main.Quotes file that was included in the zip. I then created Main.Quotes using the normal procedure for creating a new wikipage.)

Discussion

Randomquote adds the markup (:randquote:) which will be replaced by a randomly chosen line from quotes.txt.

The format for quotes.txt is one quote per line with pipes ( | ) used to denote line breaks within the quote. Each pipe will be replaced with <br> before the quote is inserted.

You can see it in action at: http://www.hostgrabber.de

If you want to avoid wikiword processing you may use the keep() function: 

 // the original code
 //	return "<div id=\"randquote\">$RandomQuote2</div>";
 // adding the keep() function
    return keep("<div id=\"randquote\">$RandomQuote2</div>");

 // To make this script work, extract it in your pmwiki/cookbook directory.
 // Then add the following line to config.php:

 //      include("cookbook/quote.php");
 //
 // Insert (:randquote:) as a markup to your wikipage.

 //
 //Changelog:
 //
 // Now  you can choose a pmwiki page, full of quotes separated by an asterisk.

 // Function to get a random line out of text file and sub <br> for | with a

 function f_RandomQuote() {

	$QuoteFile = "wiki.d/Main.Quotes";

	$Quotes = fopen($QuoteFile, "r");
	$conteudo = fread($Quotes, filesize ($QuoteFile));
	fclose ($Quotes);

	$arrConteudo = explode("\n",$conteudo);

	foreach($arrConteudo as $linha) 
		if(substr($linha,0,6) == "text=*") {
			$arrQuotes = substr($linha,6);
			$arrQuotes = str_replace("2","<BR>",$arrQuotes);// have to change the first  
                                                                        // position on str_replace, 
                                                                        // to be "2" exponential.
			$arrQuotes = explode("*",$arrQuotes);			
		}


	srand( (double)microtime() * 1000000 );
	shuffle($arrQuotes);
	return "<div id=\"randquote\">$arrQuotes[0]</div>";

} 

 // Pointer to the function
 $randQuote =& f_RandomQuote();

 // Add (:randquote:) markup that will be replaced with the quote
 Markup("randquote","directives","/\\(:randquote:\\)/",$randQuote);

I wrote it slightly differently, as I like the idea to separate the quotes by "*", the reason being that the quote page then displays nicely as a bulleted list with one quote per bullet. To do this, I used a "**" to introduce a line break inside a quote. The code goes like this: Philippe - 11/01/2005 

 foreach($arrConteudo as $linha) 
 	if(substr($linha,0,6) == "text=*") {
 		$arrQuotes = substr($linha,6);
 		$arrQuotes = str_replace("**","<BR>",$arrQuotes);
 		$arrQuotes = explode("2*",$arrQuotes);			
 	}

Replacing the 2 as an exponential 2, of course. This way, the quotes list can be like this:

  • quote 1**author 1
  • quote 2 - Line 1**Line 2**author 2
  • quote 3**author 3

What do you think ?

I like it a lot as well (the version above), but I have a problem in that it still interprets wiki words, but does not interpret wiki markups (in particular those used to prevent interpretation :) ). Does anyone have a solution for this ? Philippe - 11/01/2005

The answer to your problem is that the quotes are extracted from a pmwiki page without passing through pmwiki markup processing, just the "find & link" one. Obvious?! I know... CarlosAB

OK, thanks for the explanation, any way around this ? Philippe - 13/01/2005

Great Idea, Tiago. That makes things much more easier! -- Jens Rosenfeld (2005-01-08)

Daniel Scheibler (2005-01-15):

Changes:
  • change "2*" into "$Newline" to use wiki-specific newline character
  • change "<BR>" into "<br />" for HTML 4 Compatibility
  • meaning of config variable $QuoteFile changed; could now be changed in local.php
  • insetion of a config variable $QuoteLineDelimiter, which will be changed in <br />

important: variable configuration has to be done before include_once("cookbook/quote.php");

I have been using this with pmwiki-2.1.beta17 for a while with no unexpected results. ... I think we all know how that works though! (=

Just a side note, but when you have this set as: 

$QuoteLineDelimiter = "[[<<]]";
$QuoteRemoveItemize = true;

You can have entries like so: 

*"Do, or do not. There is no 'try'"[[<<]]~ Yoda
*"The impossible is only a little bit harder."[[<<]]~ My Grandmother.
*"When you're going through hell, keep going."[[<<]]~ Winston Churchill
*"It is better to be hated for what you are than to be loved for what you are not."[[<<]]~ Andre Gide

Which makes directly viewing the quote page(s) considerably easier. (=

Perhaps this page should be redone, so it could be a little easier to read, and some of the outdated information can be deleted. I also had some problems with the zip file not extract properly. Would be better to just put up the php script and then give instructions on this page to create Main.Quotes and perhaps some sample text to cut and paste into that page. Caveman
