如何创建签名框并使用php将该签名提交（发布）到另一个页面？

I have an HTML form where a user has fields to fill and at the end there is a signature where user has to sign. I then want all the data to be posted to another page. I posted all the fields, but I just can't post the signature

This is my signature box and its is working,

I am using a signature library from keith signature library but I just cant post the signature to another page

This is so easy you can save it as SVG by putting hidden field in your form with id someHiddenText after click or you can change event to before form submit or whatever then putting the SVG code in this hidden field.

$('#svgButton').click(function() { 
    $('#someHiddenText').val($('#captureSignature').signature('toSVG'));
});
