Question

我搜索了一个将从index.php页面获取的get变量传递给included.php文件[由javascript加载]的解决方案。 php要求函数的一个很好的解决方案是Pass and print a $_GET variable through an included file by php require function

然而，在我的情况下，我有

for index.php => url[ index.php?var=item]
    <?php
    if(isset($_GET['var'])) {
    $var=$_GET['var'];
    }
    ?>

    <script>
    $(document).ready(function(){
       $("#ok").load("included.php");
    });
    </script>

    <div id='ok'>

    </div>

 in included.php [which will be loaded in index.php by javascript load function]
 <?php
 echo $var;
 ?>

错误是included.php文件中未定义的var。如何使用php和javascript的组合来回显这个变量？

Answer 1

如果您想将这些变量传递给包含的文件，您可以使用

   $("#ok").load("included.php?<?php echo $urlString; ?>");

可以使用此功能生成URL字符串

function GenGetVars(){
    $Base = NULL;
    foreach($_GET as $key => $variable){
        $Base .= '&'.$key.'='.$variable;
    }
    return(rtrim($Base, '&'));
}

另一种选择是：

$( "#ok" ).load( "included.php", { "choices[]": [ "Jon", "Susan" ] } );

基于第一个例子：

<强>的index.php：

<?php
function GenGetVars(){
    $Base = NULL;
    foreach($_GET as $key => $variable){
        $Base .= '&'.$key.'='.$variable;
    }
    return(rtrim($Base, '&'));
}

if(isset($_GET['var']) === true) {
    $var=$_GET['var'];
}
?>

    return(rtrim($Base, '&'));
}

if(isset($_GET['var']) === true) {
    $var=$_GET['var'];
}
?>

你可以试试这个。

通过JavaScript加载文件传递并打印$ _GET变量
