[PHP] [] operator not supported for strings

[Andrew McCombe]

Hi

Can anyone tell me why i'm getting this error?

Fatal error: [] operator not supported for strings in 
c:\inetpub\wwwroot\Iweb-sites\Exp\menu2.php on line 41

[code]:


$rst2=sql_call(SELECT * FROM tmenu WHERE parent=.$r['id']);
// now have array of corporate, entertainment and identity

for ($i=0; $i  mysql_num_rows($rst2); $i++) {
 $r=mysql_fetch_array($rst2);
 $level2[$i] = $r['name'];
 $rst3 = sql_call(SELECT * FROM tmenu WHERE parent=.$r['id']);
 
 while ($a=mysql_fetch_array($rst3)) {
  $level2[$i][] = $a['name']; // giving error here
 }
 
}



[/code]

 [code]:
 
 
 $rst2=sql_call(SELECT * FROM tmenu WHERE parent=.$r['id']);
 // now have array of corporate, entertainment and identity
 
 for ($i=0; $i  mysql_num_rows($rst2); $i++) {
  $r=mysql_fetch_array($rst2);
  $level2[$i] = $r['name'];

$r['name'] will be a string -- and so, therefore, will $level2[$i] be.

  $rst3 = sql_call(SELECT * FROM tmenu WHERE parent=.$r['id']);
  
  while ($a=mysql_fetch_array($rst3)) {
   $level2[$i][] = $a['name']; // giving error here

$level2[$i] is still a string, and the [] notation when applied to a string
selects an individual character -- but you haven't specified which
character, so this is an error.

Did you mean the first assignment to $level2[$i] to start a new array that
you later add to in the loop?  In which case you might want to do

   $level2[$i] = array($r['name']);

If you meant something else, you probably need to tell us exactly what it is
you're trying to do, so we can suggest accurate solutions.

Cheers!

Mike
