小编gan*_*jan的帖子

我有一个看起来像这样的函数:

require("config.php");

function displayGta()
{
    (... lots of code...)

    $car = $car_park[3]; 
} 

和一个看起来像这样的config.php:

<?php
$car_park = array ("Mercedes 540 K.", "Chevrolet Coupe.", "Chrysler Imperial.", "Ford Model T.", "Hudson Super.", "Packard Sedan.", "Pontiac Landau.", "Duryea."); 
 (...)
?>

为什么我会收到通知:未定义的变量:car_park？

我有一点我不明白的问题.我有一个拥有所有者和类型的数据库(当然还有更多).我想得到一个列表,其中包含所有者等于当前用户的所有类型值,但我只得到两个结果

$sql = "SELECT type FROM cars WHERE owner='".mysql_real_escape_string($_SESSION['username'])."' AND selling='0' ORDER BY id DESC "; 

 $result = mysql_query($sql,$con); 

 print_r(mysql_fetch_array($result));

打印出来:

Array ( [0] => 18 [type] => 18 )

和

$sql = "SELECT type FROM cars WHERE owner='".mysql_real_escape_string($_SESSION['username'])."' AND selling='0' "; 

打印出来:

Array ( [0] => 16 [type] => 16 ) 

结果应该是数组中的19,19,18,17,16.这就是我设置为所有者的所有类型.

我现在有这个工作:

for ($x = 0; $x < mysql_num_rows($result); $x++){
 $row = mysql_fetch_assoc($result);  
 echo $row['type']; 
}

这里我正确地打印出所有值,但是我需要创建一个包含所有值的数组.我虽然可以使用array_push,但大多数都有更好的方法.我以为我会通过简单的mysql查询获得所有类型值.

我的单元测试类中有3个测试方法,但Visual Studio只运行第二个测试,忽略其他测试

这些是3种测试方法:

[TestClass()]
public class InsertionSortTest
{

    [TestMethod()]
    public void sortTest()
    {
        InsertionSort target = new InsertionSort(); // TODO: Initialize to an appropriate value
        int[] n = new int[] { 2, 1, 4 };
        int[] nExpected = new int[] { 1, 2, 4 };
        target.sort(ref n);
        CollectionAssert.AreEqual(nExpected, n);

    }

    [TestMethod()]
    public void sortTest2()
    {
        InsertionSort target = new InsertionSort(); // TODO: Initialize to an appropriate value
        int[] n = new int[] { 1, 2 };
        int[] nExpected = new …

我试过像这样的html:

<form method="post">
   <select id="select" size="2 ">
        <option value="3">test</option>
        <option value="4">test2</option>                     
   </select>
   <button type="submit" value="execute">
</form>

如何在post数组中获得3或4的值

$_POST['select']

？

我试图将我的应用程序的一部分分成一个指令,但继续得到这个:

Multiple directives [tree (module: anbud), tree (module: anbud)] asking for template on: 

这可能是由于:

Multiple directives requesting isolated scope.
Multiple directives publishing a controller under the same name.
Multiple directives declared with the transclusion option.
Multiple directives attempting to define a template or templateURL.

我有一个看起来像这样的观点:

        <tree></tree>

该指令如下所示:

(function (module) {

    var tree = function () {

        return {
            restrict: "E",
            controller: "treeController",
            templateUrl: "/app/NSviewer/templates/parts/tree.html"
        };

    };

    module.directive("tree", tree);

}(angular.module("anbud")));

我的控制器更复杂:

(function () {
    'use strict';

    angular.module('anbud')
      .controller('treeController', ['$scope', 'api', '$log', …

我的Web应用程序在Chrome,Firefox和Edge中运行良好,但当然不适用于IE 11.可能不是IE的旧版本.这是一个使用Angular Cli生成应用程序的最小应用程序.

当我的用户使用他们的用户名和用户ID保存在会话变量中时,他们可以使用paypal捐赠.使用简单的立即购买按钮,您可以简单地在贝宝生成.

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="XXX">

<img alt="" border="0" src="https://www.paypal.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form>

付款成功后,会将所有_POST数据发送到我的confirm_payment.php.我可以使用他们支付的邮件,并将其与我的用户数据库进行比较,以找到正确的用户,但我不能确定他们使用相同的电子邮件为paypal和我的网站.

我需要将$ _SESSION ['用户名']传递给paypal,这样我就可以使用这些信息自动为我的用户提供捐赠者状态.我可以添加如下内容:

<input type="hidden" name="custom" value="custom variable">

我正在PRO PHP AND JQUERY阅读本书中的一些例子,但由于某种原因,这些例子不起作用.即使我从书籍网站下载的示例也不起作用.不确定什么是错的,因为我完全按照书中所做的那样做.

当我尝试使用--prod选项运行ng build时,它会编译成一个main.js文件,并且我在控制台中没有错误.

但是当我在浏览器中运行应用程序时,它仍然会查找单个js文件.
