单选按钮选中属性 [英] Radio button checked property

问题描述

我如何知道 PHP 中的单选按钮选中属性是否为真，谁能给我一个例子?

How can I know if the radio button checked property is true in PHP, can anyone give me an example?

谢谢..

推荐答案

你可以尝试要求checked属性，看例子:

You can try to ask for the checked attribute, see the example:

<label for="public0"><input type="radio" checked="checked" name="publicar" id="public0" value="TRUE" /> YES</label>
<label for="public1"><input type="radio" name="publicar" id="public1" value="FALSE" /> NO</label>

然后在php中获取raddio按钮的值:$publicar=$postvars['publicar'];并询问它的值以便知道它是TRUE还是FALSE

Then get the value of the raddio button in php: $publicar=$postvars['publicar']; and ask for its value in order to know if it is TRUE or FALSE

另外，如果你想使用 javascript 来操作值:

In addition, if you want to manipulate the values using javascript:

if ( $("public0").checked == true) 
{ ...} or if ( $("public1").checked == true){...}
 //alert($("public0").checked); //if you want to see the value
  //alert($("public1").checked);

注意:$postvars=$_POST

Note: $postvars=$_POST
