Turn this into a function?

[mephisto_kur]

Can someone help me turn this into a function?

Code Select Expand


  global $userpic_width, $userpic_height, $facesurl;

  //BEGIN Avatar Tag Code <yabb avatar>
  $grab_avatar = mysql_query("SELECT avatar FROM {$db_prefix}members WHERE  memberName='$username'");
  while ($avatar = mysql_fetch_array($grab_avatar)) {
  if (stristr($avatar[0],"http://") ) {
  $pic = "<img src=\"$avatar[0]\" $width $height border=\"0\" alt=\"\" />";
  }
  else {
  $pic = "<img src=\"$facesurl/$avatar[0]\" border=\"0\" alt=\"\" />";
  }
  }
  $yyavatar = ($username == 'Guest' ? "<img src=\"$facesurl/blank.gif\" border=\"0\" alt=\"\" />" : "$pic");
  //END Avatar Tag Code <yabb avatar>

BTW, this is what I have:

Code Select Expand


function yyavatar()
{
   global $userpic_width, $userpic_height, $facesurl, $username, $db_prefix;
   $grab_avatar = mysql_query("SELECT avatar FROM {$db_prefix}members WHERE memberName='$username'");
   while ($avatar = mysql_fetch_array($grab_avatar))
   {
          if (stristr($avatar[0],"http://") )
          {
               $pic = "<img src=\"$avatar[0]\" $width $height border=\"0\" alt=\"\" />";
          }
          else
          {
               $pic = "<img src=\"$facesurl/$avatar[0]\" border=\"0\" alt=\"\" />";
          }
   }
   $yyavatar = ($username == 'Guest' ? "<img src=\"$facesurl/blank.gif\" border=\"0\" alt=\"\" />" : "$pic");
}


Now it doesn't give me an error, but it doesn't do *anything* either.

you need $db_prefix in your globals.

and I think you need $username too.

[mephisto_kur]

Yeah, figured that out.  Still doesn't work, tho.

[Haase]

you're not actually outputting anything.  maybe try return $yyavatar; or echo $yyavatar; or something like that.

[mephisto_kur]

I don't think you understand.  I want to use a yabb tag.

I put this in subs.php after function yylogo() but I dont think it matters where you put it and called it with <yabb avatar> and it showed the avatar *also note I did it with enigma09a!

Code Select Expand


function yyavatar()
{
   global $userpic_width, $userpic_height, $facesurl, $username, $db_prefix;
   $grab_avatar = mysql_query("SELECT avatar FROM {$db_prefix}members WHERE memberName='$username'");
   while ($avatar = mysql_fetch_array($grab_avatar))
   {
          if (stristr($avatar[0],"http://") )
          {
               $pic = "<img src=\"$avatar[0]\" $width $height border=\"0\" alt=\"\" />";
          }
          else
          {
               $pic = "<img src=\"$facesurl/$avatar[0]\" border=\"0\" alt=\"\" />";
          }
   }
   echo ($username == 'Guest') ? "<img src=\"$facesurl/blank.gif\" border=\"0\" alt=\"\" />" : "$pic";
}

This also worked 

Code Select Expand

function yyavatar()
{
   global $userpic_width, $userpic_height, $facesurl, $username, $db_prefix;
   $grab_avatar = mysql_query("SELECT avatar FROM {$db_prefix}members WHERE memberName='$username'");
   $avatar[] = mysql_fetch_array($grab_avatar);

   echo '<img src="', ($username == 'Guest') ? $facesurl.'/blank.gif"' : (stristr($avatar[0][avatar],"http://") ?
   $avatar[0][avatar].'" '.$width.' '.$height : $facesurl.'/'.$avatar[0][avatar]), ' border="0" alt="User Avatar" />';
}

YaBB SE captures output, so you have to echo it.

I've got it working as a standalone funtion, but does it *have to* be in Subs.php to be picked up as a tag?

No it can be anywhere... just as long as it's defined before the template_header() call.

Okay, let me explain exactly what is going on.  I understand what you mean, but I don't know *any* php so bear with me

I have this in a file other than Subs.php:

Code Select Expand


function yyavatar()
{
   global $userpic_width, $userpic_height, $facesurl, $username, $db_prefix;
   $grab_avatar = mysql_query("SELECT avatar FROM {$db_prefix}members WHERE memberName='$username'");
   while ($avatar = mysql_fetch_array($grab_avatar))
   {
          if (stristr($avatar[0],"http://") )
          {
               $pic = "<img src=\"$avatar[0]\" $width $height border=\"0\" alt=\"\" />";
          }
          else
          {
               $pic = "<img src=\"$facesurl/$avatar[0]\" border=\"0\" alt=\"\" />";
          }
   }
   $yyavatar = ($username == 'Guest' ? "<img src=\"$facesurl/blank.gif\" border=\"0\" alt=\"\" />" : "$pic");
   return $yyavatar;
}


If I do an "echo yyavatar();" line anywhere it gives me what I want.

Now, to make it a yabb tag, I need to define the function before the template_header is called.  How would I do that?

[[Unknown]]

Umm... I think the FUNCTION might have to echo it, not just return it.

Just means that where ever you put it... hsa to be looked at by PHP at some point.

Ahah.  That got it.  Funny thing is, I tried that before and while it did work when I used the tag, it also made it appear on every page in the upper left corner.

Thanks for the help!
