<meta charset="utf-8">

<meta name="robots" content="noindex, nofollow">

filebrowserUploadUrl: "/fileupload.php",

} );




now we are create one img folder. in this folder we are use in our custom file uploading code. our all custom file which we are uploading from PC to CKEDITOR they all file store in this folder.

Step 3: create cstom file uploading file

Now we are creating our custome file uploading file look like this "/fileupload.php"


$upload_dir = array(

'img'=> '/img/',


$imgset = array(

'maxsize' => 2000,

'maxwidth' => 900,

'maxheight' => 800,

'minwidth' => 10,

'minheight' => 10,

'type' => array('bmp', 'gif', 'jpg', 'jpeg', 'png'),


/** If 0, will OVERWRITE the existing file **/

define('RENAME_F', 1);

$re = '';

if(isset($_FILES['upload']) && strlen($_FILES['upload']['name']) >1) {

define('F_NAME', preg_replace('/\.(.+?)$/i', '', basename($_FILES['upload']['name'])));

/** get filename without extension **/

/** get protocol and host name to send the absolute image path to CKEditor **/

$site = '';

$sepext = explode('.', strtolower($_FILES['upload']['name']));

$type = end($sepext); /** gets extension **/

$upload_dir = in_array($type, $imgset['type']) ? $upload_dir['img'] : $upload_dir['audio'];

$upload_dir = trim($upload_dir, '/') .'/';

/** checkings for image **/

if(in_array($type, $imgset['type'])){

list($width, $height) = getimagesize($_FILES['upload']['tmp_name']); /** image width and height **/

if(isset($width) && isset($height)) {

if($width > $imgset['maxwidth'] || $height > $imgset['maxheight']) $re .= '\\n Width x Height = '. $width .' x '. $height .' \\n The maximum Width x Height must be: '. $imgset['maxwidth']. ' x '. $imgset['maxheight'];

if($width < $imgset['minwidth'] || $height < $imgset['minheight']) $re .= '\\n Width x Height = '. $width .' x '. $height .'\\n The minimum Width x Height must be: '. $imgset['minwidth']. ' x '. $imgset['minheight'];

if($_FILES['upload']['size'] > $imgset['maxsize']*1000) $re .= '\\n Maximum file size must be: '. $imgset['maxsize']. ' KB.';



else $re .= 'The file: '. $_FILES['upload']['name']. ' has not the allowed extension type.';

/** set filename; if file exists, and RENAME_F is 1, set "img_name_I" **/

/** $p = dir-path, $fn=filename to check, $ex=extension $i=index to rename **/

function setFName($p, $fn, $ex, $i){

if(RENAME_F ==1 && file_exists($p .$fn .$ex)) return setFName($p, F_NAME .'_'. ($i +1), $ex, ($i +1));

else return $fn .$ex;


$f_name = setFName($_SERVER['DOCUMENT_ROOT'] .'/'. $upload_dir, F_NAME, ".$type", 0);

$uploadpath = $_SERVER['DOCUMENT_ROOT'] .'/'. $upload_dir . $f_name; /** full file path **/

/** If no errors, upload the image, else, output the errors **/

if($re == '') {

/** print_r($_FILES);exit; **/

if(move_uploaded_file($_FILES['upload']['tmp_name'], $uploadpath)) {

$CKEditorFuncNum = $_GET['CKEditorFuncNum'];

$url = $site. $upload_dir . $f_name;

$msg = F_NAME .'.'. $type .' successfully uploaded: \\n- Size: '. number_format($_FILES['upload']['size']/1024, 2, '.', '') .' KB';

$re = in_array($type, $imgset['type']) ? "$CKEditorFuncNum, '$url', '$msg')" /** for img **/

: 'var cke_ob = window.parent.CKEDITOR; for(var ckid in cke_ob.instances) { if(cke_ob.instances[ckid].focusManager.hasFocus) break;} cke_ob.instances[ckid].insertHtml(\'\', \'unfiltered_html\'); alert("'. $msg .'"); var dialog = cke_ob.dialog.getCurrent(); dialog.hide();';


else $re = 'alert("Unable to upload the file")';


else $re = 'alert("'. $re .'")';


@header('Content-type: text/html; charset=utf-8');
