One thing you can do to simplify your mod is to make common code snippets into a subroutine.

I did so.

Code for the subroutine in db_utils.pl:

Code:

sub cleanup { 
#-----------------------------------------  
# get rid of extra characters  

my($input) = shift;  

        $input =~ s/ä/ae/g;

Re: [SevenSpirits] Search Engine Friendly Links II - Link Title instead of ID In reply to

If you are using 3 Level of New Graphics modification :

In this case you must change site_html_templates.pl too :
( To avoid that all detailed.html`s in the folder Detailed will be marked as updated )

Find in sub site_html_detailed the following line(s) :

Code:

# If the link is not new, check to see if it has been updated.  

elsif (&compare_dates($rec{'Datum'}, $rec{'Anmeldedatum'})) {  

# Calculate age of link based on Date Modified, not Date Added.  

$days_old = &days_old($rec{'Datum'});  

if ($days_old <= $db_new_cutoff && $rec{'istUpdate'} ne "Nein") { $new_mod_img = qq~ $updated~; }  

}

and change these lines to :

Code:

# If the link is not new, check to see if it has been updated.  

elsif (&compare_dates($rec{'Datum'}, $rec{'Anmeldedatum'})) {  

# Calculate age of link based on Date Modified, not Date Added.  

$days_old = &days_old($rec{'Datum'});  

if ($days_old <= $db_new_cutoff && $rec{'istUpdate'} ne "Nein") { $new_mod_img = qq~ $updated~; }  
if ($days_old > $db_newupdate_cutoff ) { $new_mod_img = qq~ ~; }  

}

Ignore : && $rec{'istUpdate'} ne "Nein" : because this is part of an other mod and not important for this mod.

Re: [SevenSpirits] Search Engine Friendly Links II - Link Title instead of ID In reply to

Final modification

Once again the complete modification .

My Version :
Gossamer Links V 2.01 - German translation by Nicky available at : http://www.nicky.net/

Instead of dynamic HTML Pages (generated by detail.cgi) only -
static HTML Pages will be generated by nph-build.cgi too.

What must be done?

1. Add new system fields in links.def

2. Edit links.cfg

3. Edit nph-build.cgi
3.1 Insert code of # Einschub EchteURL # into sub build_update_newpop
3.2 Insert code of # Einschub Delete $echteURLalt ---- nph-build.cgi # into sub build_update_newpop
3.3 Edit sub build_detailed_view

4. New subroutine in db_utils.pl
Add sub cleanup at the end of db_utils.pl

5. Edit detail.cgi
All entries like : http://.../cgi-bin/detail.cgi?ID=4964
will be redirected to their static html pages.

6. Edit site_html_templates.pl
If you are using 3 Level of New Graphics modification :
In this case you must edit sub site_html_detailed in site_html_templates.pl too :
( To avoid that all detailed.html`s in the folder Detailed will be marked as updated )

7. Edit aendern.cgi (aendern.cgi is used for updating entries in links.db )
Insert code of # Einschub Delete $echteURLalt -- aendern.cgi # into aendern.cgi

.

Re: [SevenSpirits] Search Engine Friendly Links II - Link Title instead of ID In reply to

1. Add new system fields in links.def

Insert into your links.def :

Code:

echteURL            => [27,  'alpha',     40,   200,  0,  '',          ''], 

echteURLalt         => [28,  'alpha',     40,   200,  0,  '',          ''],

Code:

$db_echteURL = 27;	 

$db_echteURLalt = 28;

Explanation:

$db_echteURL contains the value of <%ID%>-<%Kategorie%>-<%Titel%>
<%Titel%> ist the name of an entry.

$db_echteURLalt contains the old value of $db_echteURL if <%Titel%> and/or <%Kategorie%> were changed by an update.

$db_echteURLalt will be used to delete old static html pages of an entry in links.db .

Attachment : links.def

2. Edit links.cfg

Find these lines in your links.cfg :

Code:
# Soll die Detailierte Ansicht fuer jeden Link erstellt werden ? (1 = ja, 0 = nein).
$build_detailed = 0;
$build_detail_path = "$build_root_path/Detailiert";
$build_detail_url = "$build_root_url/Detailiert";

and change the value of $build_detailed from 0 to 1 .

Now sub build_detailed_view in nph-build.cgi
does create static HTML Pages in the folder : links/Detailed/

.

5. Edit detail.cgi

Open detail.cgi and edit sub main :

Code:

sub main { 
# --------------------------------------------------------   
  %in = &parse_form(); 

  my (%rec) = &get_record ($in{'ID'}); 

  unless ($in{'ID'}) { 
    &html_print_headers; 
    print &site_html_detailed_error ("Kein Link angegeben."); #future versions will load a form instead of an error 
  } 

#### Leitet altes URL Format auf neues HTML Format um: 
      elsif ($rec{$db_key} eq $in{'ID'}) { 

            my ($esd) = "http://.../links/Detailiert/" .$rec{'echteURL'} .".html"; 
            print "Location: $esd\n\n"; 
            } 


# Original Code:   
#  elsif ($rec{$db_key} eq $in{'ID'}) { 
#    $title_unlinked = &build_unlinked_title ("$rec{'Kategorie'}/$rec{'Titel'}"); 
#    $title_linked = &build_linked_title ("$rec{'Kategorie'}/$rec{'Titel'}"); 
#    $thiscat = $rec{'Kategorie'}; 
#    &html_print_headers; 
#    print &site_html_detailed (%rec); 
#  } 
  else { 
    &html_print_headers; 
    print &site_html_detailed_error ("Link $in{'ID'} nicht gefunden."); 
  } 
} 

### 
# Can't require nph-build -- have to copy this stuff  :-) 
###

Explanation:

The result is that old search engine entries are still valid and you dont even have to change entries in your html templates.

All entries like : http://.../cgi-bin/detail.cgi?ID=4964
will be redirected to their static html pages.

      if ($days_old > $db_newupdate_cutoff ) { $new_mod_img = qq~ ~; } 

    }

Ignore :
&& $rec{'istUpdate'} ne "Nein" : because this is part of an other mod and not important for this mod.

Add:
echteURL => $echteURL,

7. Edit aendern.cgi (aendern.cgi is used for updating entries in links.db )

Insert in sub process-form :

Code:

####################### Einschub Delete $echteURLalt --- aendern.cgi ###################################  
#####  Delete updated entries if Titel or Kategorie had been changed                                ####  

        my($esc)= $original{'Titel'}; 
           $esc = &cleanup($esc);  

##  Kategorie hinzufügen - Now let`s add the category:   
        my($esd) = $original{'Kategorie'} ."-";    
           $esd  =~ s/\//-/g; 
           $esd  =~ s/_/-/g; 

##  <%ID%> hinzufügen - Now let`s add the $db_key          
           $esd = $original{'ID'} ."-" .$esd;  

           $esd  = $esd .$esc;  

           $esd =~ tr/-/-/s; 
           $esd =~ tr/--/-/s;         # get rid of multiple - charakters  
           $esd =~ tr/[A-Z]/[a-z]/;   # change all letters to lowercase   


        $in{$db_cols[$db_echteURLalt]} = $build_detail_path ."/" .$esd .$build_extension;  

        #   $values[$db_echteURLalt] = $esd;    

####################### Einschub Delete $echteURLalt #####################################################

Code:
sub process_form {

    my ($key, $status, @values, $found, $esc, $esd, $del);

Re: [SevenSpirits] Search Engine Friendly Links II - Link Title instead of ID In reply to

We built in this mod into our public Download Section : http://downloads.supernature-forum.de/links/

As you can see we changed the mod a littlebit :
Instead of <%ID%>-<%Category%>-<%Title%> we only use <%ID%>-<%Title%>.
(The link becomes smaller this way)

Feel free to visit our site and to try out the functions there.
