现在我正在用php学习angular js。我将尝试上传文件和存储在mysql数据库中的文件名
task.html
<!DOCTYPE html>
<html>
<script src="js/shared/angular.min.js"></script>
<body ng-app="myApp" ng-controller="myCtrl">
<div class="file-upload">
<input type="text" ng-model="name">
<input type="file" file-model="myFile"/>
<button ng-click="uploadFile()">upload me</button>
</div>
<script type="text/javascript" src="app.js"></script>
</body>
</html>
在这种情况下，上传按钮无法处理任何内容。
app.js
var myApp = angular.module('myApp', []);
myApp.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};
}]);
myApp.service('fileUpload', ['$http', function ($http) {
this.uploadFileToUrl = function(file, uploadUrl, name){
var fd = new FormData();
fd.append('file', file);
fd.append('name', name);
$http.post(uploadUrl, fd, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined,'Process-Data': false}
})
.success(function(){
console.log("Success");
})
.error(function(){
console.log("Success");
});
}
}]);
myApp.controller('myCtrl', ['$scope', 'fileUpload', function($scope, fileUpload){
$scope.uploadFile = function(){
var file = $scope.myFile;
console.log('file is ' );
console.dir(file);
var uploadUrl = "save_form.php";
var text = $scope.name;
fileUpload.uploadFileToUrl(file, uploadUrl, text);
};
}]);
在这个应用程序中，.js将被执行，但它不会转到save_form.php
save_form.php
<?php
include_once "db.php";
$target_dir = "/upload/";
$name = $_POST['name'];
print_r($_FILES);
$target_file = $target_dir . basename($_FILES["file"]["name"]);
move_uploaded_file($_FILES["file"]["tmp_name"], $target_file);
//write code for saving to database
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO MyData (name,filename) VALUES ('".$name."','".basename($_FILES["file"]["name"])."')";
if ($conn->query($sql) === TRUE) {
echo json_encode($_FILES["file"]); // new file uploaded
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
但是在这个上传按钮中不能处理任何
我测试了相同的代码，它运行得很好。这是我在angularjs文件夹中的index.php文件
