背景:
用户上传图像并单击“保存”按钮。
我成功地将图像保存到服务器中。我给了文件夹 777 权限....
问题:
我尝试打开图像，但它无法正常显示:Image url
HTML
<button class ="save" onclick="test()">Save image to server</button>
脚本:
function test(){
var canvas = document.getElementById("0");
var dataURL = canvas.toDataURL(); // THE BASE 64 DATA
var dataFileName = document.getElementById('fileup').value.replace(/.*(\/|\\)/, ''); // GET THE FILE NAME THAT USER CHOSE
var dataFileType = dataFileName.split('.').pop();
$.ajax({
type: "POST",
url: "tamaker.php",
data: {
imgBase64: dataURL,
imgFileName: dataFileName,
imgFileType: dataFileType
}
}).done(function(o, imgFileName) {
console.log(o);
var response = JSON.parse(o);
console.log(response);
$('body').prepend('<img src="' + dataFileName+ '" style="height: 200px; width: auto;">');
});
}
保存.php
<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
if( isset($_POST['imgBase64']) && isset($_POST['imgFileName']) && isset($_POST['imgFileType']) ){
$fname = filter_input(INPUT_POST, 'imgFileName'); // THE FILENAME THE USER CHOSE IS RECEIVED VIA POST
$img = filter_input(INPUT_POST, 'imgBase64'); // THE BASE64 ENCODING RECEIVED VIA POST
$imgtype = filter_input(INPUT_POST, 'imgFileType'); // THE FILE TYPE / EXTENSION IS RECEIVED VIA POST
// STRIP OFF THE BEGINNING OF THE BASE64 DATA, BUT DEPENDS ON THE IMAGE TYPE.
// I COULD HAVE SIMPLIFIED THIS BUT USED IF STATEMENTS.
if ( $imgtype === 'png'){
$img = str_replace('data:image/png;base64,', '', $img);
};
if ( $imgtype === 'jpg' || $imgtype === 'jpeg'){
$img = str_replace('data:image/jpeg;base64,', '', $img);
};
if ( $imgtype === 'gif'){
$img = str_replace('data:image/gif;base64,', '', $img);
};
// REPLACE ALL SPACES IN THE IMAGE DATA WITH PLUS SYMBOL
$img = str_replace(' ', '+', $img);
// CONVERT THE DATA FROM BASE64 ENCODING
$img = base64_decode($img);
// SAVE THE FILE WITH NAME SYNTAX OF: /images/clientlogos/[ACCOUNT ID]_[FILE NAME]
file_put_contents('/var/www/html/ecom1/site/test/screen/'.$fname, $img);
echo "Image has been saved successfully!<p>";
}
?>
