resize only selected images

[tryingtolearn]

Hi again

 

I have an image upload script that is resizing every image that a user uploads.

What I would like to do is have a check box added to the upload form that a user can check to resize the image if they want to or leave it unchecked to just upload the image.

 

So if the box is checked the original image gets uploaded and a resized image is created as well

If the box is not checked just the original image uploaded.

 

I tried adding a check box but every image still was resized - checked or not - Im assiming because it was in the foreach loop so I dont know what to do.

 

This is what I have right now

 

FORM CODE
<b>File [<?php echo $x; ?>]:</b><br> <input type="file" name="upload[]" size="10"/>


PROCESS CODE
if (!(isset($_POST['folder']))) {
echo"<H1><span style=\"color: #ff1111;\">PROCESS ERROR</span></H1><br>We did not receive your information to process.<br>Please go <a href=\"img_manager.php\">back</a> and input your information again.";
exit(); // Quit the script.
include ('./includes/footer.html');
}

foreach ($_POST['folder'] as $p) {

			$pa = $p;
			}

			$query = "SELECT path FROM img_folder WHERE folder_id=$pa";
			$result25 = mysql_query ($query);
			while ($row = mysql_fetch_array($result25, MYSQL_ASSOC)) {
			$resultpath = $row['path'];
			}
			echo"<p>Return to the <a href=\"img_manager.php\">Image Manager</a> </p><br>";
if (!is_dir("images/$user_id/$resultpath")) {
  $oldumask = umask(0);
  mkdir("images/$user_id/$resultpath", 0777);
  umask($oldumask);
}
$num = $_POST['num'];
//start_process
// Check if the form has been submitted.

Any ideas/ help appreciated.

Thanks

Does this mean there is no way to do it or does anyone have an idea of how to change it up to make it work?

I didn't really do much more than skim through your code, but use the checkbox in a form with method post, then check that variable using $_POST['resize'] ('resize' being whatever the name of your checkbox is), try this:

 

if(!empty($_POST['resize']) {

  //do resize code

  } else {

  //do not resize code

  }

 

No guarantees though, sorry I can't be more help.

Thanks,

That is how I started originally but it was resizing every pic loaded.

I dont understand it.

 

maybe I will just start from scratch with it.
