Problem with var and class

[kumschick]

Hi all,

why doesn't this with work? Why can't I use a varable for the var in a class?

$getfileextention = "bat";

if($username=="administrator") {
  $getfileextention = "bat";
}

else {
  $getfileextention = "$username.bat";
}

class listfiles{

  var $version="1.0";
  var $myfileextensions="($getfileextention)\$"; // <- THIS DOESN'T WORK / VAR = NULL
  var $myrestrictedfiles="/|^\\.";

  function showlist($batchpath,$font_face,$font_size,$font_color,$mt,$username,$fileextention){
    $mydirectory=opendir($batchpath);
    while($entryname=readdir($mydirectory)){
      $a = eregi($this->myfileextensions,$entryname);
      $b = !eregi($this->myrestrictedfiles,$entryname);
      if ( $a && $b){
        $myfiles["$entryname"]=$entryname;
      }
    }

   ...

The problem you're experiencing involves variable scope. Change your one line to read:

...
var $myfileextensions="($_GLOBALS['getfileextention'])\$";
...

And you should have success. Then I'd suggest reading up on scope in PHP.

it doesn't work! 🙁
here is the hole code

$getfileextention is still NULL

<?php

...
              $batchpath = "$homepath/wap/exec/";
              include("$homepath/option/list.mrm");
              $lf= new listfiles; $lf->showlist($batchpath,$font_face,$font_size,$font_color,$mt,$username);
...

?>


<?php
//INCLUDE


if($username=="administrator") {
  $getfileextention = "$username.bat";
}
else {
  $getfileextention = "bat";
}


class listfiles {

  var $version="1.0";
  var $myfileextensions="($_GLOBALS['getfileextention'])\$"; 
  var $myrestrictedfiles="/|^\\.";

  function showlist($batchpath,$font_face,$font_size,$font_color,$mt,$username){
    $mydirectory=opendir($batchpath);
    while($entryname=readdir($mydirectory)){
      $a = eregi($this->myfileextensions,$entryname);
      $b = !eregi($this->myrestrictedfiles,$entryname);
      if ( $a && $b){
        $myfiles["$entryname"]=$entryname;
      }
    }

if (is_array($myfiles)) {
  asort($myfiles);

  $i=0;
  while (list($name,$value)=each($myfiles))
    {

    $i++;
    if ($i%2) { $bgcolorm="bgcolor=\"#DADFF7\""; } else { $bgcolorm="bgcolor=\"#B7BFE5\""; }

      echo"
        <tr $bgcolorm>
          <td valign=\"top\" align=\"center\"><font face=\"$font_face\" size=\"$font_size\" color=\"$font_color\">&nbsp;<a href=\"/adm_batch_edit.mrm?mt=$mt&do=Edit&id=$name\"><img alt=\"Edit Batch File\" border=\"0\" src=\"/images/button_edit.png\"></a>&nbsp;&nbsp;&nbsp;<a href=\"/adm_batch_edit.mrm?mt=$mt&do=Delete&id=$name\" onclick=\"return confirmSubmit()\"><img alt=\"Delete Batch File\" border=\"0\" src=\"/images/button_drop.png\"></a>&nbsp;</font></td>
          <td valign=\"top\" align=\"left\"><font face=\"$font_face\" size=\"$font_size\" color=\"$font_color\"><a title=\"Run $name now!\" href=\"/adm_batch_edit.mrm?mt=$mt&do=Run&id=$name\">$name</a></font></td>
        </tr>
      ";

    }
}
else
{
      echo"
        <tr $bgcolorm>
          <td valign=\"top\" colspan=\"2\"><font face=\"$font_face\" size=\"$font_size\" color=\"$font_color\">&nbsp;No Batchfiles Found&nbsp;</font></td>
        </tr>
      ";
}
closedir($mydirectory);
  }

}
?>

The docs you read and tell you they will 😃

In PHP 4, only constant initializers for var variables are allowed. To initialize variables with non-constant values, you need an initialization function which is called automatically when an object is being constructed from the class. Such a function is called a constructor
