PHP Resize any uploaded file

[kamal213]

Hi Guys,

 

I have this script below which inserts the file name and path into my datebase and uploads the file into the customers folders (which is creates dynamically).

 

The is no error checking as I want it to be as flexible as possible but mostly(99.999%) the files I upload are JPEG and PDF's.

 

I would like my script to be able to resize the files above automatically to be smaller.

 

Please is this possible thanks!

 

Here is script:

<?php 
//Will create a directory once a customer is clicked and will not if page is refreshed an so forth 
		 if (file_exists('customerUploads/' . $check_id . ', ' . $c_name . '')) {

		} else {
		  mkdir('customerUploads/' . $check_id . ', ' . $c_name . '');
		}
?>
<?php 
//This php block of code will takecare of inserting the upload variables into the db

if(isset($_POST['submitbutton'])) {

$target_path = 'customerUploads/' . $check_id . ', ' . $c_name . '/';
$target_path = str_replace("'","",$target_path);		
$target_path = $target_path . basename( $_FILES['upload']['name']);
$manager= mysql_real_escape_string($_POST['username']);
$upload =  $_FILES['upload']['name'];
$upload = str_replace("'","",$upload);
$check_id = mysql_real_escape_string($_POST['id']);
$submitbutton= mysql_real_escape_string($_POST['submitbutton']);


if($submitbutton)
{
if($manager&&$upload)
{
if (file_exists($target_path))
{
echo $_FILES["upload"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["upload"]["tmp_name"],$target_path);

echo "Stored in: " . 'customerUploads/' . $check_id . ', ' . $c_name . '/' . $_FILES["upload"]["name"];

$insert=mysql_query("INSERT INTO img_up (username,upload,id,target_path,img_date) VALUES ('$manager','$upload','$check_id','$target_path', now()) ");

		// Where the file is going to be placed 
		$target_path = 'customerUploads/' . $check_id . ', ' . $c_name . '/';

		/* Add the original filename to our target path.  
		Result is "uploads/filename.extension" */
		$target_path = $target_path . basename( $_FILES['upload']['name']); 

		$target_path = 'customerUploads/' . $check_id . ', ' . $c_name . '/';

		$target_path = $target_path . basename( $_FILES['upload']['name']); 

		if (file_exists($target_path))
		{
		echo $_FILES["upload"]["name"] . " already exists. ";
		}
		else
		{
		move_uploaded_file($_FILES["upload"]["tmp_name"],$target_path);
		echo "Stored in: " . 'customerUploads/' . $check_id . ', ' . $c_name . '/' . $_FILES["upload"]["name"];
		}


}
}
else
{
echo "There was an error uploading the file, please try again!";
}
}
 header("location: mainupload_complete.php?id=$check_id"); 
}
?>

Where are you stuck? And what exactly do you mean by resizing them to be smaller? Do you mean file size or image dimensions?

[kamal213]

Thanks for getting back!

 

The image dimension exactly.

 

Basically after the file have been uploaded I display a link in the front-end were user can click to view the file, so the problems is when user click on the link (especially pdf's) its open and its about 230% zoom and they keep changing it to about 80-90%.

 

I want to make it smaller automatically to about 80-90% save them the hassle of doing it manually everytime so i figure have to somehow resize the dimension so it looks smaller when users open the file.

EXAMPLE

<?php
// The file
$filename = 'test.jpg';
$percent = 0.5;

// Content type
header('Content-Type: image/jpeg');

// Get new dimensions
list($width, $height) = getimagesize($filename);
$new_width = $width * $percent;
$new_height = $height * $percent;

// Resample
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

// Output
imagejpeg($image_p, null, 100);
?>

Thanks for your reply!

 

This seems like its from the GD Library I would prefer ImageMagik as it allows PDF'S

 

[voip03]

Do you want the code or guidance

[trq]

PDF's are not images.

[kamal213]

Is there a way2 resize them? to make the appear smaller automatically when you open them?
