当我试图更新我的表单上的文件时，我得到了这个错误…"您没有选择要上传的文件。"．..问题是我实际上是在选择一个新文件来上传…请帮帮我，我不明白发生了什么…下面是我的代码:
形式<form class="col s12" id="update_form" required="" enctype="multipart/form-data" aria-required="true" name="update_form" method="post" >
<div class="row">

}
有两个名称属性具有相同的值animation。
<input type="file" name="animation">
和
<input class="file-path validate" id="animation" name="animation" type="text">
第二个name属性覆盖第一个。你需要给它一个不同的名字
修改Ajax代码:
$("#update_politic_btn").click(function(event) {
var chango = new FormData($("#update_form")[0]);
// try this if above one not work
//var chango = new FormData($("#update_form"));
$.ajax({
url: baseurl + 'admin/update_politic',
type: 'POST',
data: chango,
async: false,
success: function (data) {
console.log(data);
list_politic();
},
cache: false,
contentType: false,
processData: false,
error : function() {
}
});
event.preventDefault();
});
