Question

我有一个问题，我正在尝试传递由html form输入的变量 - ＆gt;通过angularJS - ＆gt;传递给PHP。变量包括：proverbDescription，proverbNumber和imgPath（图片的路径）。

单击图像submit button时，图像的路径将上传到phpMyAdmin;但是没有上传proverbDescription和proverbNumber。相反，我收到以下错误：

Notice: Trying to get property of non-object in C:\xampp\htdocs\web\php\addProverbs.php on line 6

Notice: Trying to get property of non-object in C:\xampp\htdocs\web\php\addProverbs.php on line 7

可能出错了什么？我试图将变量更改为$proverbDescription = $prov['proverbDescription'];但不幸的是，没有任何效果。

下面，请找到PHP代码。

<?php
$prov = json_decode(file_get_contents("php://input"));
require_once("connection.php");

$connection = connectToMySQL();
$proverbDescription = $prov->proverbDescription;
$proverbNumber = $prov->proverbNumber;
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {

    $target_dir = "../uploads/";
    $target_file = $target_dir . basename($_FILES['imageToUpload']['name']);
    $uploadOk = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
    $check = getimagesize($_FILES['imageToUpload']['tmp_name']);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }

// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES['imageToUpload']['size'] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES['imageToUpload']['tmp_name'], $target_file)) {
        echo "The file ". basename( $_FILES['imageToUpload']['name']). " has been uploaded.";
        $query = "INSERT INTO tbl_proverb (proverbDescription, proverbNumber, imgPath) VALUES ('$proverbDescription', '$proverbNumber', '$target_file')";
        $result = mysqli_query($connection, $query)
             or die("Error in query: ". mysqli_error($connection));
        if(mysqli_affected_rows($connection) > 0){
                $success = true;
        }else{
                $success = false;
        }
        exit();
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
}

?>

如果您需要，请在此处找到angularJS controller：

app.controller('proverbCtrl', function($scope, $http, $location) {  
    $scope.addProverb = function(prov) {
        $http.post('php/addProverbs.php', prov).success(function(prov) {
            console.log(prov);
        //  $location.path("/proverbs");
        });
    };
});

非常感谢你的帮助！
