"<br>";    }    else    {       echo "upload: " . $_files["file"]["name"] . "<br>";       echo "type: " . $_files["file"]["type"] . "<br>";       echo "size: " . ($_files["file"]["size"] / 1024) . " kb<br>";       echo "temp file: " . $_files["file"]["tmp_name"] . "<br>";        if (file_exists("../soundclips/" . $_files["file"]["name"]))       {          echo $_files["file"]["name"] . " exists. ";       }       else       {          move_uploaded_file($_files["file"]["tmp_name"],          "../soundclips/" . $_files["file"]["name"]);          echo "stored in: " . "../soundclips/" . $_files["file"]["name"];       }    } } else {     echo "invalid file"; } 

and form

<form class='form1' action='../inc/soundclips.php' method='post'                                                         enctype='multipart/form-data'>    <input type="hidden" name="id" value="<?php echo $pid; ?>"/>    <b>add soundclip <i><?php echo $e;?></i> </b>     <?php echo"<divclass='editimage'>";    echo "<img class='resizedimage' src='{$row['image']}' />";    echo"</div>";?><br />     <b>song</b><br /><input type=text size='60' name='asong' /><br />    <input name='file' type="file" id="file"  /><br />    <input type='submit' name='add' value='add soundclip' /> </form> 

looks mp3 file cannot uploaded, missing in $_files array. might due size compared image files.

please check upload_max_filesize , post_max_size settings php.ini , allow greater size mp3 file.
