Hi wechinee,

Even bought the extension plugin, worked like a breeze, so I’ll be able to prototype the site on a test installation, then replicate it when going live. And of course, being able to have backups at any time in case of mishap…

Hi Anders,

Here’s my final code, including :
– A log function to allow debugging, plus my detailed debug lines,
– Use of variables to make S&R code more readable, debug-friendly and customizable,
– Customization of the 1st search’s $strSearch value according to my configuration.

	/**
	 * Send to debug.log if WP_DEBUG is defined and true
	 *
	 * @since  2.2.0
	 *
	 * @param  string $function Function name
	 * @param  int    $line     Line number
	 * @param  mixed  $msg      Message to output
	 * @param  mixed  $debug    Variable to print_r
	 */
	public static function log_if_debug( $function, $line, $msg, $debug = null ) {
		if ( defined( 'WP_DEBUG' ) && WP_DEBUG ) {
			error_log( "In $function, $line:" . print_r( $msg, true ) . ( $debug ? print_r( $debug, true ) : '' ) );
		}
	}

	//Rewrite links and image tags
	function rewrite ( $text, $mode='images' ) {
		//Log parameters when WP_DEBUG is set to True
		self::log_if_debug( __METHOD__, __LINE__, '==== BEGIN DEBUG ====' );
		self::log_if_debug( __METHOD__, __LINE__, 'wikidir : '.$this->wikidir );

Hi Anders,

Should have seen that in the first place : my MW URLs are not in the same form as yours. It could be, that I use a very old MW, or a parameter (I’ll have to upgrade it anyway, but for now I’ll work around the issue temporarily).

Basically, your format is

index.php/PageName

when mine is

index.php?title=PageName

Now the URLs get rewritten, but they are not recognized by the page.

I get a rewritten URL in the form

http://test.hoshikaze.net/wordpress-5.0.2-fr_FR/presentation-de-lunivers/especes/?wikipage=PageName

Hi Anders,

I’ve modified the rewrite() function as follows to issue debug logs :

	/**
	 * Send to debug.log if WP_DEBUG is defined and true
	 *
	 * @since  2.2.0
	 *
	 * @param  string $function Function name
	 * @param  int    $line     Line number
	 * @param  mixed  $msg      Message to output
	 * @param  mixed  $debug    Variable to print_r
	 */
	public static function log_if_debug( $function, $line, $msg, $debug = null ) {
		if ( defined( 'WP_DEBUG' ) && WP_DEBUG ) {
			error_log( "In $function, $line:" . print_r( $msg, true ) . ( $debug ? print_r( $debug, true ) : '' ) );
		}
	}

	//Rewrite links and image tags
	function rewrite ( $text, $mode='images' ) {
		//Log parameters when WP_DEBUG is set to True
		self::log_if_debug( __METHOD__, __LINE__, 'wikidir : '.$this->wikidir );
		self::log_if_debug( __METHOD__, __LINE__, 'wikiurl : '.$this->wikiurl );
		self::log_if_debug( __METHOD__, __LINE__, 'text before           : \n'.$text );
		//Rewrite links to other wiki pages
		$text = str_replace( '/'.$this->wikidir.'/index.php/', '?wikipage=',$text );
		self::log_if_debug( __METHOD__, __LINE__, 'text after 1          : \n'.$text );
		//Rewrite other relative links
		$text = str_replace( '/'.$this->wikidir,$this->wikiurl, $text );
		self::log_if_debug( __METHOD__, __LINE__, 'text after 2          : \n'.$text );
		//Rewrite image
		if( $mode == 'images' ) {
			$text = $this->rewrite_images( $text );
			self::log_if_debug( __METHOD__, __LINE__, 'text after images : \n'.$text );
		}
		return $text;
	}
