它打印进位:数组,因为这正是它的本质。您需要对其进行循环(第一个循环中的另一个循环)才能访问其中的值:

foreach($_POST as $key => $val) {
    if($key == 'carry') {
        foreach($val as $carry) {
            $body .= $carry;
        }
    }
    else {
        $body .= $key . " : " . $val . "\r\n";
    }
}

这完全未经测试,但希望逻辑是合理的:)

It's printing carry: Array because that's exactly what it is. You need to loop over it (another loop inside the first) to access the values inside:

foreach($_POST as $key => $val) {
    if($key == 'carry') {
        foreach($val as $carry) {
            $body .= $carry;
        }
    }
    else {
        $body .= $key . " : " . $val . "\r\n";
    }
}

That's completely untested but hopefully the logic is sound :)

要获取 Android 源代码的特定分支,您可以像获取最新版本一样使用存储库。按照其他答案提供的链接中设置机器的信息说明进行操作后,您将运行

repo init -u https://android.googlesource.com/platform/manifest -b cupcake 

这将提取 1.5 版本的源代码。

To get a specific branch of the android source, you use the repo just like you would to get the latest version. After you follow the instructions on the info for setting up the machine in the links that were supplied by the other answers, you would run

repo init -u https://android.googlesource.com/platform/manifest -b cupcake 

That will pull the 1.5 version of the source code.

在哪里以及如何找到和下载 Android 1.5 源代码?

可能您的 PHP cli 使用不同的 php.ini 文件,该文件加载 json 扩展,而 Apache 模块则不然。 php -iphpinfo() 提供有关加载的 php.ini 文件的信息。

对于 PHP cli,可以通过 PHPRC 环境变量或使用 php -c 指定 php.ini 位置。对于 Apache 模块,您可以使用 Apache 指令 PHPINIDir

Probably your PHP cli is using a different php.ini file, one that loads the json extension, and the Apache module isn't. php -i and phpinfo() give information about the loaded php.ini files.

For PHP cli, the php.ini location can be specified through the PHPRC environment variable or with php -c <file|dir>. For the Apache module, you can use the Apache directive PHPINIDir.

PHP JSON。令人困惑的问题

通常返回返回/错误代码,并提供带有结果的属性或成员。

int retCode = myobject.doSomething();
if (retCode < 0){ //Or whatever you error convention is
   //Do error handling
}else{
   long val = myobject.result;
}

传入设置为返回值的指针并返回返回/错误代码也很常见。 (请参阅HrQueryAllRows)。

long val = INIT_VAL;
int retCode = myObject.doSomething(&val);

if (retCode < 0){
    //Do error handling
}else{
    //Do something with val...
}

It is common to return a return/error code, and make available a property or member with the results.

int retCode = myobject.doSomething();
if (retCode < 0){ //Or whatever you error convention is
   //Do error handling
}else{
   long val = myobject.result;
}

It is also common to pass in a pointer that is set to the return value, and return the return/error code. (See HrQueryAllRows).

long val = INIT_VAL;
int retCode = myObject.doSomething(&val);

if (retCode < 0){
    //Do error handling
}else{
    //Do something with val...
}

在 C++ 中返回错误代码的正确方法是什么?

试试这个,如果第一个选择返回 rows ,那么如果第一个失败则返回,然后下一个选择返回或最后一个选择:

IF EXISTS(SELECT * FROM Customers 

     INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID where Customers.CustomerID='BERJGS')
    BEGIN
             SELECT * FROM Customers 
                    INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID where Customers.CustomerID='BERJGS'
              PRINT 'TOLA'
              RETURN
     END
ELSE
     BEGIN
               SELECT * FROM Customers 
                    INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID where Customers.CustomerID='6CHOPS'             
              IF @@ROWCOUNT > 0             
                    RETURN              
              --RETURN
     END



SELECT * FROM Customers  where Customers.CustomerID='FRANK'

Try this, if the first select return rows , then it returns if the first fails then the next select returns or finally the last select:

IF EXISTS(SELECT * FROM Customers 

     INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID where Customers.CustomerID='BERJGS')
    BEGIN
             SELECT * FROM Customers 
                    INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID where Customers.CustomerID='BERJGS'
              PRINT 'TOLA'
              RETURN
     END
ELSE
     BEGIN
               SELECT * FROM Customers 
                    INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID where Customers.CustomerID='6CHOPS'             
              IF @@ROWCOUNT > 0             
                    RETURN              
              --RETURN
     END



SELECT * FROM Customers  where Customers.CustomerID='FRANK'

您可以使用很多框架来简化框架的使用并提高效率。

我更喜欢 Spring Webflow。它处理会话状态,使用简单,您可以利用 spring 提供的其他功能(IoC/依赖注入、集成功能、Spring Batch ...)

当您可以自由使用不同的语言/api 时,您应该有一个查看 Grails

You can use a lot frameworks to simplify framework usage and boost efficience.

I would prefer Spring Webflow. It handles conversational state, is simple to use and you can take profit of the other features spring offers (IoC/Dependency Injection, Integration features, Spring Batch ...)

When you have the freedom to use different languages/apis you should have a look at Grails.

有哪些更好的 Java Web 应用程序框架(请提出建议)?

你是对的,我想它确实破坏了索引器。

我的解决方法是下载 QT 库的完整源代码,将其提取到某处并将其添加到 eclipse 包含路径中。显然它不会选择它们进行编译,也不会执行任何操作,但至少自动完成功能可以正常工作。

You are right, I guess it does break the indexer.

The workaround for me was downloading a complete source of the QT lib, extract it somewhere and add that to the eclipse include path. It obviously won't pick them up to compile nor anything but at least the auto-completion works ok.

QT编程:mac上的eclipse自动完成功能不起作用

我认为您不一定需要重新设计,您可能只想将 AntiXSS 部分添加到您的 BLL 中即可。

为了避免 XSS 攻击,您需要接受来自富文本编辑器的用户输入并将其保存到数据库中。然后,当用户输入从数据库返回到屏幕时,您需要对其进行编码,以便

既然您说您的 BLL 返回一个集合到 UI,我应该说您需要调用 AntiXSS 编码方法的点是从数据库中的行创建集合的点。如果您发布代码的相关部分,我们应该能够准确地看到哪里需要更改。

I don't think you need to redesign necessarily, you might want to add the AntiXSS piece to your BLL is all.

To avoid XSS attacks, you need to accept user input from the rich text editor and save that to your database. Then when the user input is returned from the database to the screen, you need to encode it so that <script> tags don't get rendered out as <script>, they get rendered as <script> which will stop them executing in the browser.

Since you say that your BLL returns a collection to the UI, I should say that the point you need to be calling the AntiXSS encoding methods is the point at which the collection is created from the rows in the database. If you post the relevant section of your code, we should be able to see exactly where the changes are needed.

Apple 在 3.2+ 中更改了一些 API,我们必须反映我们的 API 来更改它们。

您可以使用以下其中一项:

 movie.movieControlStyle = Titanium.Media.VIDEO_CONTROL_EMBEDDED;
 movie.movieControlStyle = Titanium.Media.VIDEO_CONTROL_FULLSCREEN;
 movie.movieControlStyle = Titanium.Media.VIDEO_CONTROL_NONE;

Apple changed some of the APIs in 3.2+ and we've had to reflect our APIs to change them.

You can use one of the following:

 movie.movieControlStyle = Titanium.Media.VIDEO_CONTROL_EMBEDDED;
 movie.movieControlStyle = Titanium.Media.VIDEO_CONTROL_FULLSCREEN;
 movie.movieControlStyle = Titanium.Media.VIDEO_CONTROL_NONE;

使用 Java 默认策略文件格式分配权限的最精细粒度是按代码源(即按 JAR 或按类目录)。作为解决方法,您可以将每个具有明显特权的类拆分到 WEB-INF/lib 中其自己的 JAR 中,并向该 JAR 授予特定权限。

可以创建自定义类加载器来为每个定义类创建唯一的保护域。 ProtectionDomain 可以静态授予每类权限,也可以创建专门的 ProtectionDomain 以允许自定义策略动态授予每类权限。

The finest granularity for assigning permissions using the Java default policy file format is per-code source (i.e., per-JAR or per-class-directory). As a workaround, you could split each distinctly privileged class into its own JAR in WEB-INF/lib and grant specific permissions to that JAR.

A custom ClassLoader could be made to create unique ProtectionDomains for each defineClass. The ProtectionDomains could either statically grant per-class permissions, or they could create specialized ProtectionDomains to allow a custom Policy to dynamically grant per-class permissions.

授予单个类权限

有什么东西不能与 CurrentDB.Collat​​ingOrder 一起使用吗?我不知道你在哪里查找结果数字的值,但在我的美国数据库中,它返回 1033,这是非常熟悉的美国英语字符集。

啊,是的,如果我进入 VBE 中的对象浏览器并搜索 Collat​​ingOrder,其中一个结果会显示一个名为 Collat​​ingOrderEnum 的 ENUM,通过依次单击每个,您可以看到它的值。

DBEngine(0)(0).Collat​​ingOrder 是相同的属性,并且可以与外部 Access 中的 DAO 一起使用。也许有一种方法可以使用 ADO/OLEDB 来获取它,但我不使用它们中的任何一个,因此无法为您指明正确的方向。

Is there something not working with CurrentDB.CollatingOrder? I don't know where you look up the value of the resulting number, but in my American DBs, it returns 1033, which is quite familiar as the American English character set.

Ah, yes, if I go into the Object Browser in the VBE and search for CollatingOrder, one of the results shows an ENUM called CollatingOrderEnum, and by clicking on each in turn, you can see its value.

DBEngine(0)(0).CollatingOrder is the same property, and can be used with DAO from outside Access. There is, perhaps, a way to get it with ADO/OLEDB, but I don't use either of them so can't point you in the right direction there.

查看 JSDT wiki 页面,发现 Javascript 编辑器的语法检查和其他功能似乎并未内置到 JSP 编辑器中。我也有同样的抱怨。

http://wiki.eclipse.org/JSDT

请注意,并非所有 Javascript 编辑器扩展点都受支持然而。我假设这些扩展是必要的,以便将您想要的 Javascript 编辑器功能集成到 JSP 编辑器中。

Looking at the JSDT wiki page, it appears that syntax checking and other features of the Javascript editor are not built into the JSP editor. I have the same complaint.

http://wiki.eclipse.org/JSDT

Note that not all the Javascript editor extension points are supported yet. I am assuming these extensions are necessary in order to integrate the Javascript editor features you want into the JSP editor.

JSP 文件中的 Javascript 语法检查不起作用
