Thank you for taking time to read this.
How to embed signature into the emails with php?
Facts:
- The database column for signature is varchar(max)
- When I draw the signature in a php form signature field, It saves the signature data.
Example of the data after the signature captured in the database: data:image/jsignature;base30,3S7flha3Z55hic5Y5b1vi63Z2952Ybmi40Z44Yaef630034hc5301a9810Z20Y748953112343_3OZ3aef97Y18jhd81Zdk62Y6gh95Z4761Y6b8Zbb52Y2b9Z38k9Y1a94Zdb9Y48j9Z87ee64Y46ih83
- I am using phpmail sender and tried to add the signature field as below
$mail_message = ' <b>Doctor’s Signature:</b> '.{DoctorSignature}.' <br> <b>date:</b> '.{date}.' '
- using jsignature for the signature (Not png)
Solution
This is a signature made with jsignature and needs to be parsed as such. I'm not sure if this work in E-Mail but the following code should do the trick:
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js" integrity="sha512-894YE6QWD5I59HgZOGReFYm4dnWc1Qt5NtvYSaNcOP+u1T9qYdvdihz0PPSiiqn/+/3e7Jo4EaG7TubfWGUrMQ==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>
<script src="https://cdn.jsdelivr.net/gh/brinley/jSignature@master/libs/jSignature.min.js"></script>
<div id="PrintSignatureController">
</div>
<script>
$(document).ready(function() {
$("#PrintSignatureController").jSignature({
'decor-color': 'transparent',
'lineWidth': 1,
});
$("#PrintSignatureController").jSignature("importData", "data:image/jsignature;base30,3S7flha3Z55hic5Y5b1vi63Z2952Ybmi40Z44Yaef630034hc5301a9810Z20Y748953112343_3OZ3aef97Y18jhd81Zdk62Y6gh95Z4761Y6b8Zbb52Y2b9Z38k9Y1a94Zdb9Y48j9Z87ee64Y46ih83");
});
</script>
I assume that an E-Mail does not execute JavaScript. In this case, I don't see a way around translating the signature first into base64, which can then be used in a tag.
This is not as pointed but perhaps interesting: https://stackoverflow.com/a/47467731/11781125
