[英]How to Convert SVG to image (JPEG, PNG, etc.) in the browser and save on server for product preview to checkout
在使用base64結賬之前,我正在使用html2canvas轉換svg以在服務器端保存為png產品預覽。 svg工作正常。 這是一個定制的項目結帳。 問題是在單擊自定義和結帳后,svg圖像在結賬前不會保存到結帳頁面上預覽。 原因是我不知道要寫什么來保存它的PHP。 我需要幫助編寫“savetoserver.php”的php代碼以保存到服務器
function imagetopng(){
function showCheckout() {
$("#checkoutcontainer").show();
$(".productoverview").show();
$("#popup").show();
}
setTimeout(showCheckout, 500);
html2canvas($(".stole"), {
allowTaint: true,
letterRendering: true,
onrendered: function(canvas) {
$('.stole-png').prepend(canvas);
var dataURL = canvas.toDataURL('image/png', 1.0);
$.ajax({
type: "POST",
url: "savetoserver.php",
data: {
imgBase64: dataURL
}
})
.done(function(o) {
var fileurl = o;
var websiteurl = "http://woven.indexsta.com/";
var formatted = websiteurl + fileurl;
//var formatted = "stole-designs/" + fileurl
$('#stole-url').attr('value', formatted);
$('#stolepreview').attr('src', fileurl);
// If you want the file to be visible in the browser
// - please modify the callback in javascript. All you
// need is to return the url to the file, you just saved
// and than put the image in your browser.
});
}
});
$('.stole-png').empty();
};
$('#closecheckout').on('click touch',function(){
$("#checkoutcontainer").css('display','none');
$("#popup").css('display','none');
});
I figured it out. Incase anyone faces same challenge, here's the script i wrote to solve it.
<?php
// requires php5+
// create directory
if (!file_exists('images/')) {
mkdir('images/', 0777, true);
}
define('UPLOAD_DIR', 'images/');
$img = $_POST['imgBase64'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = UPLOAD_DIR . uniqid() . '.png';
$success = file_put_contents($file, $data);
print $success ? $file : 'Unable to save the file.';
?>
