ok friends

 

i have found a function for resize and upload image

 

i have put it to admin/includes/classes/uplaod.php

 

and call it when image upload function called up.

 

 

here is the function

 

<?php
function getExtension($str) {
$change="";
 $i = strrpos($str,".");
 if (!$i) { return ""; }
 $l = strlen($str) - $i;
 $ext = substr($str,$i+1,$l);
 return $ext;
}
function resize_upload_image($image_name,$image_temp_path,$small_image_path)
{
 $change="";

 $errors=0;

 $image =$image_name;//File name
 $uploadedfile = $image_temp_path;//Temp path of file

 if($image) 
 {
  $small_filename = stripslashes($image_name);
  $extension = $this->getExtension($small_filename);
  $extension = strtolower($extension);

  if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) 
  {
   $error .='Unknown Image extension \n';
   $errors=1;
  }
  else
  {   
   if($extension=="jpg" || $extension=="jpeg" )
   {
    $uploadedfile = $image_temp_path;
    $src = imagecreatefromjpeg($uploadedfile);     
   }
   else if($extension=="png")
   {
    $uploadedfile = $image_temp_path;
    $src = imagecreatefrompng($uploadedfile);     
   }
   else 
   {
    $src = imagecreatefromgif($uploadedfile);
   }
   echo $scr;

   list($width,$height)=getimagesize($uploadedfile);

   $newwidth1=150;
   $newheight1=150;

   if($height < $width){
    $newheight1=($height/$width)*$newwidth1;
   }else{
    $newwidth1=($width/$height)*$newheight1;
   }

   $tmp1=imagecreatetruecolor($newwidth1,$newheight1);

   imagecopyresampled($tmp1,$src,0,0,0,0,$newwidth1,$newheight1,$width,$height);

   if($errors == 0){
    //Set path of image
    $filename1 = $small_image_path;
    //Upload image   
    imagejpeg($tmp1,$filename1,100); 
    imagedestroy($src);
    imagedestroy($tmp1);
    return true;
   }else{return false;}
  }
 }
}
?>
