KevNRox Posted August 4, 2015 Share Posted August 4, 2015 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> <meta charset="utf-8"> <title>Full-Window · Signature Pad</title> <style> * { -webkit-user-select: none; -moz-user-select: none; user-select: none; } html, body { min-height: 100%; height: 100%; max-width: 100%; width: 100%; overflow: hidden; } html, body, form { margin: 0px; } html, form { padding: 0px; } html, body, fieldset { background: #aaa; } fieldset { position: absolute; border: 5px solid #aaa; background: #aaa; right: 0px; bottom: 0px; } canvas { outline: 5px solid #aaa; background: #fff; } input[type=submit], input[type=reset] { font-size: larger; } </style> <link rel="stylesheet" href="assets/jquery.signaturepad.css"> <!--[if lt IE 9]><script src="../assets/flashcanvas.js"></script><![endif]--> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script> </head> <body> <form method="post" action="finaladd.php" class="sigPad"> <div class="sig sigWrapper"> <div class="typed"></div> <canvas class="pad" width="198" height="55"></canvas> <input type="hidden" name="output" class="output"> <fieldset> <input type="reset" value="clear" /> <input type='submit' value='submit'/> </fieldset> </div> <button type="submit">I accept the terms of this agreement.</button> </form> <script src="assets/numeric-1.2.6.min.js"></script> <script src="assets/bezier.js"></script> <script src="jquery.signaturepad.js"></script> <script> (function(window) { var $canvas, onResize = function(event) { $canvas.attr({ height: window.innerHeight, width: window.innerWidth }); }; $(document).ready(function() { $canvas = $('canvas'); window.addEventListener('orientationchange', onResize, false); window.addEventListener('resize', onResize, false); onResize(); $('form').signaturePad({ drawBezierCurves: true, variableStrokeWidth:true, drawOnly: true, defaultAction: 'drawIt', validateFields: false, lineWidth: 0, output: null, sigNav: null, name: null, typed: null, clear: 'input[type=reset]', typeIt: null, drawIt: null, typeItDesc: null, drawItDesc: null }); }); }(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.

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. Quote Link to comment Share on other sites More sharing options...
ignace Posted August 4, 2015 Share Posted August 4, 2015 (edited) Add this line to finaladd.php $json = $_POST['output']; var_dump($json, json_decode(stripslashes($json)));And post the output here. Edited August 4, 2015 by ignace Quote Link to comment Share on other sites More sharing options...

gizmola Posted August 5, 2015 Share Posted August 5, 2015 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); Quote Link to comment Share on other sites More sharing options...
