form_input.php
var create_pdf = document.getElementById("create_pdf");
create_pdf.addEventListener('click', function (event) {
html2canvas($('#pdf_wrap')[0] ,{
//logging : true,
//proxy: "html2canvasproxy.php",
allowTaint : true,
useCORS: true,
scale : 2
}).then(function(canvas) {
var imgData = canvas.toDataURL('image/jpeg');
var doc = new jsPDF("p", "px");
var options = {
pagesplit: true
};
var imgWidth = 210;
var pageHeight = 295;
var imgHeight = canvas.height * imgWidth / canvas.width;
var heightLeft = imgHeight;
var doc = new jsPDF('p', 'mm');
var position = 0;
doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
heightLeft -= pageHeight;
while (heightLeft >= 0) {
position = heightLeft - imgHeight;
doc.addPage();
doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
heightLeft -= pageHeight;
}
//Send mail on other php
$.post("mail_send.php",
{
data: doc.output('datauristring')
}, function () {}).done(function() {/*SOME CODE*/});
// doc.save( 'file.pdf');
});

You need to double check your data, but I think is the problem
$base = explode('data:application/pdf;base64,', $_POST['data']);
$mail->addStringAttachment($base, 'pdfName.pdf');
This will not result in a PDF attachment; it will result in a base64-encoded PDF attachment tagged as a PDF, which will then be base64-encoded a second time by PHPMailer because it can't know what data you are providing. So decode the PDF data before attaching it:
$mail->addStringAttachment(base64_decode($base), 'pdfName.pdf');
