PhpDig.net - Regular Expression Fix

Hi. A regex used in PhpDig versions 1.6.3 and 1.6.4 does not permit certain characters like ß in a search. To fix this do the following.

In search_function.php find:

PHP Code:


		
			
if (eregi("[^[:alnum:]^ +^-]+",$query_to_parse)) { $query_to_parse = eregi_replace("[^[:alnum:]^ ]+"," ",$query_to_parse); }

and replace with the following:

PHP Code:


		
			
$what_query_chars = "[^".$phpdig_words_chars[PHPDIG_ENCODING]." -]+";

if (eregi($what_query_chars,$query_to_parse)) {

    $query_to_parse = eregi_replace($what_query_chars," ",$query_to_parse);

}

Also in search_function.php find:

PHP Code:


		
			
// init variables

and right after add the following:

PHP Code:


		
			
global $phpdig_words_chars;
