Please help me with my script

[kelly3330]

Hello i am quite new with php, and i have designed a small content management system, it uploads images but in a very large scale. I have tried lots of different ways to implement thumbnail script into my code but im getting no where. I have just found this very small function script that makes my images into thumbnails, well its supposed to but im not having any luck. If someone could help me or at least point me in the right direction of getting this working i would extremely appreciate it.

 

here is my code.

Start.php

 

<form enctype="multipart/form-data" action="add.php" method="POST">
Name: <input type="text" name="name"><br>
Description: <input type="text" name="description"><br>
Price: <input type="text" name="price"><br>
Photo: <input type="file" name="photo"> <br>
<input type="submit" value="add">
</form>

 

// Connects to the Database



mysql_connect("localhost", "root", "") or die(mysql_error()) ;

mysql_select_db("cars") or die(mysql_error()) ;



//Retrieves data from MySQL

$data = mysql_query("SELECT * FROM cars") or die(mysql_error());



//Puts it into an array

while($info = mysql_fetch_array( $data ))

{



//Outputs the image and other data

Echo "<img src=images/".$info['photo'] ."> <br>";

Echo "<b>Name:</b> ".$info['name'] . "<br> ";

Echo "<b>Description:</b> ".$info['description'] . " <br>";

Echo "<b>Price:</b> ".$info['price'] . " <hr>";



} 

 

//This is the directory where images will be saved

$target = "images/";

$target = $target . basename( $_FILES['photo']['name']);



//This gets all the other information from the form

$name=$_POST['name'];

$description=$_POST['description'];

$price=$_POST['price'];

$pic=($_FILES['photo']['name']);



// Connects to your Database

mysql_connect("localhost", "root", "") or die(mysql_error()) ;

mysql_select_db("cars") or die(mysql_error()) ;



//Writes the information to the database

mysql_query("INSERT INTO cars VALUES ('$name', '$description', '$price', '$pic')") ;



//Writes the photo to the server

if(move_uploaded_file($_FILES['photo']['tmp_name'], $target))

{



//Tells you if its all ok

echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has 



been added to the directory";

}

else {



//Gives and error if its not

echo "Sorry, there was a problem uploading your file.";

} 

 

 

**********This is my imageresize function which is what i am having problems with getting it to work in with the rest of my scripts this is what i am trying to get working with the other scripts***********

 

 

    function resizeImage($pic,$toWidth,$toHeight){

    

    // Get the original geometry and calculate scales

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

    $xscale=$width/$toWidth;

    $yscale=$height/$toHeight;

    

    // Recalculate new size with default ratio

    if ($yscale>$xscale){

        $new_width = round($width * (1/$yscale));

        $new_height = round($height * (1/$yscale));

    }

    else {

        $new_width = round($width * (1/$xscale));

        $new_height = round($height * (1/$xscale));

    }



    // Resize the original image

    $imageResized = imagecreatetruecolor($new_width, $new_height);

    $imageTmp     = imagecreatefromjpeg ($pic);

    imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0, $new_width, $new_height, $width, $height);



    return $imageResized;

}

My advice would be to use this instead, it's something I wrote a while ago...

 

function set_image_pro($image,$type,$size,$tmp)
{
define ("MAX_SIZE","500");

if ((($type == "image/gif")
|| ($type == "image/jpeg")
|| ($type == "image/pjpeg"))
&& ($size < MAX_SIZE*1024))
  {
  if ($_FILES["image"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["image"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $image . "<br />";
    echo "Type: " . $type . "<br />";
    echo "Size: " . ($size / 1024) . " Kb<br />";

if (file_exists("images/origimg/" . $image))
      {
      echo $image . " already exists. ";
      }
    else
      {
  move_uploaded_file($tmp,"images/origimg/".$image);
  $origim="images/origimg/".$image;
  $thumbim="images/".$image;
  $thumbw="400";
  $thumbh="400";
  $this->set_createthumb($origim,$thumbim,$thumbw,$thumbh);
  $origim="images/".$image;
  $thumbim="images/thumbs/".$image;
  $thumbw="150";
  $thumbh="150";
  $this->set_createthumb($origim,$thumbim,$thumbw,$thumbh);
      echo "Stored in: " . "images/" . $image;
  echo "<h1>Uploaded Successfully</h1>";
      }
    }
  }
else
  {
  echo "Invalid file";
  echo "Type: " . $type;
  }
}

function set_createthumb($name,$filename,$new_w,$new_h)
{
$system=explode('.',$name);
if (preg_match('/jpg|jpeg/',$system[1]))
{
$src_img=imagecreatefromjpeg($name);
}
if (preg_match('/png/',$system[1]))
{
$src_img=imagecreatefrompng($name);
} 
$old_x=imageSX($src_img);
$old_y=imageSY($src_img);
if ($old_x > $old_y)
{
$thumb_w=$new_w;
$thumb_h=$old_y*($new_h/$old_x);
}
if ($old_x < $old_y)
{ $thumb_w=$old_x*($new_w/$old_y);
$thumb_h=$new_h;
}
if ($old_x == $old_y)
{
$thumb_w=$new_w; $thumb_h=$new_h;
} 
$dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);
imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y); 
if (preg_match("/png/",$system[1]))
{
imagepng($dst_img,$filename);
}else{
imagejpeg($dst_img,$filename);
}
imagedestroy($dst_img);
imagedestroy($src_img);
}

 

You need to use the following file structure with this script....

 

A folder called 'images', a folder inside images called 'origimg', a folder inside images called 'thumbs'. To use this function you call it like so, setting the parameters when you call the function...

 

$image=$_FILES["image"]["name"];
$type=$_FILES["image"]["type"];
$size=$_FILES["image"]["size"];
$tmp=$_FILES["image"]["tmp_name"];
$title=$_POST['title'];
$text=$_POST['text'];

$image_pro->set_image_pro($image,$type,$size,$tmp);
