mod: small improvements for 1.8.7

[blueyed]

Display URL with "not found" messages:
replace line 531 in spider.php, which is:

PHP Code:

print $s_no.phpdigMsg('error').' 404'.$br; 


into

PHP Code:

print $s_no.phpdigMsg('error').' 404 ('.str_replace('@url',$url_indexing,$s_link).')'.$br; 


Fix.. in line 113 of libs/function_phpdig_form.php I've changed

PHP Code:

$relative_script_path = '.'; 


to

PHP Code:

global $relative_script_path; 


because otherwise I'll get "Unable to find connect.php file for dropdown menu."


Change request: use a constant/variable for:

• temp directory (line 464 of admin/spider.php), because this has to be writeable and "/tmp" is probably more appropriate in most cases
• URI to the phpdig directory. This would be useful for lines 671 & 708 in libs/search_function.php (lines 738 & 775 in search_function.php that I'll post later).
