如何使用 AJAX 添加 PHP Session 变量到 FormData 中?
How to add PHP Session variable into FormData using AJAX?
我想使用 FormData 和 AJAX 传递一个 PHP 会话变量(称为 'profileid')。我认为下面这个会起作用,但没有。为什么?
var imageData = new FormData();
imageData.append('image', $('#uploadImage')[0].files[0]);
imageData.append('profileid', <?php echo $_SESSION['profileid'];?>);
//Make ajax call here:
$.ajax({
url: '/upload-image-results-ajax.php',
type: 'POST',
processData: false, // important
contentType: false, // important
data: imageData,
//leaving out the rest as it doesn't pertain
您可以在 $.ajax
URL 参数中添加 profileid 而不是在 FormData 中添加它:
$(document).ready(function (e) {
$('#uploadImageForm').on('submit',(function(e) {
e.preventDefault();
var formData = new FormData(this);
$.ajax({
url: "/upload-image-results-ajax.php?profileid=<?= $_SESSION['profileid']; ?>",
type: "POST",
data: formData,
cache: false,
contentType: false,
processData: false,
success: function(response){
console.log("success");
console.log(response);
},
error: function(response){
console.log("error");
console.log(response);
}
});
}));
$('#uploadImage').on("change", function() {
$("#uploadImageForm").submit();
});
});
不要忘记将 session_start();
放在代码的开头。
