嘗試從files [0]屬性建立一個json對象,将檔案轉換為base64字元串
JS
$("#image").on("change", function(e) {
var name = $("#af_rpta_propertyland_filename").val()
, file = e.target.files[0]
, filename = name.length > 1 ? name + ".pdf" : file.name
, filetype = file.type
, filesize = file.size
, data = {
"filename":filename,
"filetype":filetype,
"filesize":filesize
}
, reader = new FileReader();
reader.onload = function(e) {
data.file_base64 = e.target.result.split(/,/)[1];
$.post("fileupload.php", {file:data}, "json")
.then(function(data) {
// parse `json` string `data`
var filedata = JSON.parse(data)
// do stuff with `data` (`file`) object
, results = $("", {
"href": "data:" + filedata.filetype
+ ";base64," + filedata.file_base64,
"download": filedata.filename,
"target": "_blank",
"text": filedata.filename
});
$("body").append("
download:", results[0]);
}, function(jqxhr, textStatus, errorThrown) {
console.log(textStatus, errorThrown)
})
};
reader.readAsDataURL(file)
});
PHP
if (isset($_POST["file"])) {
// do php stuff
// call `json_encode` on `file` object
$file = json_encode($_POST["file"]);
// return `file` as `json` string
echo $file;
};
