-

i have been trying upload stream of files using following code, 

<form enctype="multipart/form-data" action="carousel_update.php?id=<?php echo $id;?>" method="post"> for($j = 1 ; $j <= $n ; $j++)   {         echo "<option value='$j'>$j</option>";     }     echo "</td></tr>     <tr><td>title:</td><td><input type=\"text\" name=\"title[$i]\"></td></tr>     <tr><td>image: </td><td><input type=\"file\" name=\"picture$i\"></td></tr>     <tr><td>description:</td><td><textarea name=\"description[$i]\"></textarea></td></tr>     <tr><td>link text: </td><td><input type=\"text\" name=\"link_text[$i]\"></td></tr>     <tr><td>link url: </td><td><input type=\"text\" name=\"link_url[$i]\"></td></tr>     <tr><td>link target: </td><td><input type=\"text\" name=\"link_target[$i]\"></td></tr></table></fieldset>";         }     } ?> <input type="submit" value="submit">

in action file carousel_update.php, 

for($i = 1; $i<=$n ; $i++)  {     $file = "picture".$i;     $order = $_post['order'][$i];     $title = $_post['title'][$i];     $description = $_post['description'][$i];     $linktext = $_post['link_text'][$i];     $linkurl = $_post['link_url'][$i];     $linktarget = $_post['link_target'][$i];     $target = dirname(__file__). "/images/".$_files[$file]["name"];     if(move_uploaded_file($_files[$file]["tmp_name"], $target)) {         echo "uploaded";     }     else    {         echo "problems in uploading file";     } }
