[Resolved] undefined function..

[stew]

i get an error after trying to call a function previous included from another file...

i know the function is there but its not defined apparently.

i read another thread about this on here, and it said that this can sometimes be caused by a missing " or } but ive checked the script and there are no parse errors appearing...

any ideas? could it be a setting in the php.ini file?

hmm

Can you post the offending code?

[Weedpacket]

And the text of the error message?

ok... here is a function in the file gallery.php. this i sone of maybe ten or so functions that are called from the index.php file depending on the action.

function show_type() {
  $cat = $_GET["action"];
  $limit = $_GET["limit"];
  echo("<div align=\"center><center><table cellpadding=\"1\" cellspacing=\"3\" width=\"90%\"><tr><td width=\"100%\" align=\"right\" colspan=\"2\">Photo Gallery</td></tr>
  <tr><td width=\"100%\" align=\"left\" colspan=\"2\"><BR></td></tr>
  <tr><td width=\"100%\" align=\"left\" colspan=\"2\">Live</td></tr>
  <tr><td width=\"100%\" align=\"left\" colspan=\"2\"><BR></td></tr>
  <tr><td width=\"100%\" align=\"left\" colspan=\"2\"><div align=\"center\"><center><table align=\"center\" width=\"100%\"><tr>");
  $recent_live = mysql_query("SELECT * FROM gallery WHERE img_cat = '$cat' ORDER BY upload_date DESC LIMIT $limit, 12");
  $p = 1;

  while(($recent_live1 = mysql_fetch_array($recent_live)) && ($p <= 12)) {
    $img_thumb_url = $recent_live1["img_thum_url"];
    $img_x = $recent_live1["img_x"];
    $img_y = $recent_live1["img_y"];
    $uploaded_on = $recent_live1["uploaded_on"];
    $img_id = $recent_live1["img_id"];
    $uploaded_by = $recent_live1["uploaded_by"];
    $uploaded_on = strftime($timeformat,$uploaded_on);
    echo("**Stuff**");
    if($p == 4 || $p == 7 || $p == 10) { echo("</tr><tr>"); }
    $p++;

  }

  echo("</tr> <tr><td width=\"100%\" align=\"left\" colspan=\"2\"><BR></td></tr>
  <tr><td width=\"100%\" align=\"left\" colspan=\"2\">");
  $pages = mysql_num_rows(mysql_query("SELECT * FROM gallery WHERE img_cat = '$cat'"));
  $pages = ceil($pages / 12);

  $cur = ($limit / 12) + 1;
  echo("Page: ");

  for($d=1;$d<=$pages;$d++)  {
     $e = ($d - 1) * 15;
     if($cur == $d) { echo("<font color=\"#ffffff\">$d</font>"); }
     else { echo("<a href=\"index.php?action=$cat&limit=$e\">$d</a> "); }
  }





}

the function itself is called from the index.php file if the file has been included, using call_user_func.

the error i get is:
Fatal error: Call to undefined function: call_user_function() in /data/sites/asdkfj/www/web/v2/gallery/index.php on line 30

...but i thought that call_user_func() was the correct thing to use... if im wrong your going to have to spell it out...

🙁

[mrhappiness]

the error messages claims that you're trying to call a function with the name "call_user_function" which does not exists and i'm apt to believe that 🙂

go to line 30 in your index.php and try chaning call_user_function to call_user_func and see what happens

[stew]

ok... now i get this error...

"First argument is expected to be a valid callback "

[tekky]

then you erroniously called call_user_func()

[stew]

meaning that the function itself doesn't actually exist?!

[tekky]

no... meaning you should past the line that has the call_user_func() on it so we can see if we spot your mistake, theres something wrong with the function name you are passing as the call_back, so actually paste the appropriate code that shows that function being defined too
