I have installed and am using Thomas bradleys Signature pad. I am able to draw my signature but when I press submit I keep getting this error

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\CareMed\signature-to-image.php on line 52

I am using the full-window template so it only had a clear button. I added a submit button to it.

 

 

This is the main php page that lets me draw my signature.


<html><head>

          });
        };

    $(document).ready(function() {
      $canvas = $('canvas');
      window.addEventListener('orientationchange', onResize, false);
      window.addEventListener('resize', onResize, false);
      onResize();

      $('form').signaturePad({

    });
  }(this));
  </script>
  <script src="assets/json2.min.js"></script>

This is now the page called finaladd.php

 

This is where it ges when I click submit. It is supposed to convert the image into a png and save it as signature.png

<?php

require_once 'signature-to-image.php';

$json = $_POST['output'];
$img = sigJsonToImage($json);

imagepng($img, 'signature.png');
imagedestroy($img);

// Destroy the image in memory when complete

Lastly,

 

This is the signature-to-image.php file that is called from the above file.

If you are not familier with this. Please see the following...

 

I am using this

 

http://thomasjbradley.ca/lab/signature-pad/

 

I am then trying to make it a png by using this...

 

http://thomasjbradley.ca/lab/signature-to-image/

 

When you go into the first link..

 

Please go into the examples foolder and look at the file called full-window.html

 

That is the one i am trying to use. It does not have a submit button which is weird and I had to add one. But its not working and that is my problem.

I don't see an issue with the code. Is there anything in your apache or php logs?

 

With that said, the code:

 

imagepng($img, 'signature.png');
is going to attempt to write the file in the current working directory where that script is running. Your permissions may not be allowing a file to be written there. Try providing the full path to a directory and filename you are sure has write access for the user apache is running as.

 

I'm not much help there because I don't use windows/xamp etc.

 

You should also try and turn off the warning level while debugging this.

 

Try adding:

 

error_reporting(E_ERROR | E_PARSE);
