yabb.info Member Map

[powergen]

By itself it works ...

http://www.betasom.it/forum/Sources/BetasomMap_Image_0.php

[Chris Cromer]

Move it from the sources directory to the forum directory and change all the links in the source to point to it in the forum directory instead.

[Michele]

Chris, did you get my email yesterday?

Thanks, Moya

[powergen]

Chris I have found the problem.

It's all fault of the $sourcedir variable that does work well ....

.... but just for scripts ...

In the <img src= .... > tag you have to put the clear path to the second php file ...

I have just used another variable for doing that and that's it !


 

Thanks for your help !!

powergen

[Chris Cromer]

That is the reason I told you to change it. The sourcedir var has the directory of it not the url.

[powergen]

hehehe, thanks Chris .....


Next time I'll listen to you just from the start !!

The point is that I really like to understand things on my own ...

I know I have asked help ... but just after the first tip, I really want to scour and find the why underneath ...

I'm having a small problem with the member map and YaPP... perhaps Chris or Jedi can find the problem?

I created a page in Admin (index.php?page=map) that looks like this:

Code Select Expand

global $imagesdir, $ID_MEMBER, $db_prefix, $HTTP_GET_VARS, $settings;
   if ($HTTP_GET_VARS['t'] == 2 && $settings[7] != 'Administrator')
      $HTTP_GET_VARS['t'] = 0;

   if ($HTTP_GET_VARS['t'] == 1 && $ID_MEMBER==-1)
      $HTTP_GET_VARS['t'] = 0;

   if ($HTTP_GET_VARS['t'] == 0)
   {
      if (isset ($HTTP_GET_VARS['submitted']) && $HTTP_GET_VARS['submitted'] && $ID_MEMBER != -1)
      {
         $request = mysql_query ("SELECT * FROM pre_world_map WHERE ID_MEMBER=$ID_MEMBER");
         if (mysql_num_rows($request) > 0)
            $request = mysql_query ("UPDATE pre_world_map SET xPos=$HTTP_GET_VARS[map_x], yPos=$HTTP_GET_VARS[map_y] WHERE ID_MEMBER=$ID_MEMBER");
         else
            $request = mysql_query ("INSERT INTO pre_world_map (ID_MEMBER,xPos,yPos) VALUES($ID_MEMBER, $HTTP_GET_VARS[map_x], $HTTP_GET_VARS[map_y])");
      }       
   }

   if ($ID_MEMBER == -1)
   {
      print "<font face=verdana,size=1><center><img src=\"worldmap_image.php\"></center>";    
   }
   else
   {
      if ($settings[7] == 'Administrator')
      {
         $adminTxt = "     <input type=radio name=t value=2>Delete Pin";
          
      }
print "<font face=verdana,size=1><form action=\"index.php\" method=get><input type=hidden name=page value=\"map\"><center><input type=image src=\"worldmap_image.php?me=$ID_MEMBER&t=$HTTP_GET_VARS[t]&x=$HTTP_GET_VARS[map_x]&y=$HTTP_GET_VARS[map_y]\" name=map onclick=\"submit()\" style=\"cursor:crosshair\">      <br> <input type=radio name=t value=1 checked>Who is this?     <input type=radio name=t value=0>Place My Pin$adminTxt</center><input type=hidden name=submitted value=1></form>";    
   }
print <<<EOT
The most recent pin addition is highlighted by a blue circle, and your location is indicated by a blue pin. The AC²M member map is a map of all members who are registered on AC²M and who have indicated their position on the world map.  If you haven't yet placed yourself, click on the map above to place your pin.   You can move your pin around at any time.  Also, you can only place a pin if you are a registered member and are logged in.</font>Please note that <b>Who is this?</b> isn't quite working yet.<p>
<hr width="80%">
EOT;
obexit();
Everything works except for when you click on "Who Is This?" then I get no pic. DELETE and ADD A PIN work fine though. Also, the obexit() stuff is preventing the copyright stuff from loading yet I get no error. If I remove obexit() I get errors in subs.php (or was it ssubs.php?).

The worldmap_image.php is in the same directory as the forums, and the image is in YaBBImages. Here's what worldmap_image.php looks like:

Again, everything works but the "Who is This" button, and I've been going over this code for several hours now and can't find it. You can see it not working right here:

http://ac2m.computers4gaming.com

Then click on "Where in Dereth? Link on the left. I've set up a dummy login account with a name of "testuser" and a password of "testpass" - let me know if you can figure out what's going on, I'm running on empty here.

Thanks, Mad Moya

[Chris Cromer]

That isn't going to work because it uses the variable action while making a page in YaPP uses the variable page. The only way for this to work is for you to edit the source code and put it in yourself.

[Michele]

Well, it was mostly working when I posted the message, now it's not working at all for some reason...

Are you talking about the <form action="index.php" stuff? If so, I'll take a look at it and start playing and see what I come up with.

Thanks, MM

Maybe I can get Chris to integrate the member map into YaPP, with permission of course

(I would, but 1.) I know nothing about it and 2.) I can't even see the stupid thing. )

[Michele]

Hehe, the map stopped working this morning, and my site stopped working sometime this evening, so I'm not surprised you couldn't see it.

Still awaiting a reply from my host's tech support. It looks like the Nameserver for my site is down, as I can still get there via the IP address.

There seems to be an issue with the line

imagejpeg ($im)

Sometimes it displays the map fine, sometimes it outputs gibberish, and sometimes it just outputs a broken link. I tried converting the jpeg to png, but it went from a 55K jpeg to a 450K png, so that wasn't a good solution.

Have fun, Moya

The only problem is that the gd library must be installed for it to work. Should I put it into YaPP anyway?

[Michele]

Don't most hosts enable the gd library?

If you do integrate it, just remember to put a place for us to change the map file used!

Have fun, Moya

You wouldn't be using xnull would you?  My site and xnull itself both seem to be down, with myown site disappeared from the DNS.

Chris, make sure you do that
