PHP and If Statements
===

Ok, so I am trying to add an if statement inside of an if statement.  I want it so if the user is logged in (sessions have been coded), the user will be able to access our public file uploader.  So, heres my code.

    <?php
    session_start();
    
    if ($_SESSION['loggedin'] == true) {
         $max_no_img=4; // Maximum number of images value to be set here
          echo "<form method=post action='' enctype='multipart/form-data'>";
          echo "<table border='0' width='400' cellspacing='0' cellpadding='0' align=center>";
          for($i=1; $i<=$max_no_img; $i++){
          echo "<tr><td>Images $i</td><td>
          <input type=file name='images[]' class='bginput'></td></tr>";
                         }
          echo "<tr><td colspan=2 align=center><input type=submit value='Add Image'></td></tr>";
          echo "</form> </table>";
          while(list($key,$value) = each($_FILES['images']['name']))
               {
              //echo $key;
              //echo "<br>";
              //echo $value;
              //echo "<br>";
          if(!empty($value)){   // this will check if any blank field is entered
          $filename =rand(1,100000).$value;    // filename stores the value
    
          $filename=str_replace(" ","_",$filename);// Add _ inplace of blank space in file name, you can remove this line
    
          $add = "upload/$filename";   // upload directory path is set
          //echo $_FILES['images']['type'][$key];     // uncomment this line if you want to display the file type
          //echo "<br>";                             // Display a line break
          copy($_FILES['images']['tmp_name'][$key], $add); 
          echo $add;
              //  upload the file to the server
          chmod("$add",0777);                 // set permission to the file.
          }
                     } else {
    echo "Test";
    }
    ?>
