MODS.DB9.DK

[srt]

I was told this mod will show a users total time spent on the forum itself with this mod. Ive been looking at forums with it installed and I'm not seeing this feature. Is it really there?

[acoolwelshbloke]

Yes you will see it in the users profile!

click on memberlist and then click on a persons username to see their profile details.

Edit:
I misread your post, It shows to registered users in the profile section the last time they were online but it will only show the total online time etc to administrators.

[srt]

oo

I'm somewhat of a new person to php/phpbb and what not. But I could just copy this code into the profile area and make it visible to all right? Would anyone be able to help me with this?

[acoolwelshbloke]

No problem.

When installing the mod, where it tells you to add the code below in the templates/subSilver/profile_view_body.tpl:

Code: Select all

<!-- Start add - Last visit MOD -->
<tr>
   <td valign="middle" align="right"><span class="gen">{L_LOGON}:&nbsp;</span></td>
   <td width="100%"><b><span class="gen">{LAST_LOGON}</span></b></td>
</tr>
<!-- BEGIN switch_user_is_moderator -->
<tr>
  <td valign="middle" align="right"><span class="gen">{L_TOTAL_ONLINE_TIME}:&nbsp;</span></td>
  <td width="100%"><b><span class="gen">{TOTAL_ONLINE_TIME}</span></b></td>
</tr>
<tr>
  <td valign="middle" align="right"><span class="gen">{L_LAST_ONLINE_TIME}:&nbsp;</span></td>
  <td width="100%"><b><span class="gen">{LAST_ONLINE_TIME}</span></b></td>
</tr>
<tr>
  <td valign="middle" align="right"><span class="gen">{L_NUMBER_OF_VISIT}:&nbsp;</span></td>
  <td width="100%"><b><span class="gen">{NUMBER_OF_VISIT}</span></b></td>
</tr>
<tr>
<td valign="middle" align="right"><span class="gen">{L_NUMBER_OF_PAGES}:&nbsp;</span></td>
<td width="100%"><b><span class="gen">{NUMBER_OF_PAGES}</span></b></td>
</tr>
<!-- END switch_user_is_moderator -->
<!-- End add - Last visit MOD -->

Instead of inserting the above code, insert this one instead:

Code: Select all

<!-- Start add - Last visit MOD -->
<tr>
   <td valign="middle" align="right"><span class="gen">{L_LOGON}:&nbsp;</span></td>
   <td width="100%"><b><span class="gen">{LAST_LOGON}</span></b></td>
</tr>
<tr>
  <td valign="middle" align="right"><span class="gen">{L_TOTAL_ONLINE_TIME}:&nbsp;</span></td>
  <td width="100%"><b><span class="gen">{TOTAL_ONLINE_TIME}</span></b></td>
</tr>
<tr>
  <td valign="middle" align="right"><span class="gen">{L_LAST_ONLINE_TIME}:&nbsp;</span></td>
  <td width="100%"><b><span class="gen">{LAST_ONLINE_TIME}</span></b></td>
</tr>
<tr>
  <td valign="middle" align="right"><span class="gen">{L_NUMBER_OF_VISIT}:&nbsp;</span></td>
  <td width="100%"><b><span class="gen">{NUMBER_OF_VISIT}</span></b></td>
</tr>
<tr>
<td valign="middle" align="right"><span class="gen">{L_NUMBER_OF_PAGES}:&nbsp;</span></td>
<td width="100%"><b><span class="gen">{NUMBER_OF_PAGES}</span></b></td>
</tr>
<!-- End add - Last visit MOD -->

The information you want will be shown to all!

Thank you very much, but sadly I havent been able to get that far with the mod. I have played with the code you provided several times to no prevail. I then tried to debug it with EM mod. I'm not quite frusterated and am stuck with this sessions.php file.

This is the error:

Code: Select all

Fatal error: Call to a member function on a non-object in /home/padejlho/public_html/forum/includes/sessions.php on line 134


This is my bad sessions file.

Code: Select all
