Question

我试图将值传递给PHP页面，该页面将响应要加载的PHP代码。我的问题是返回的PHP代码部分工作。

AJAX：

$.ajax({
  type: 'post',
  url: 'bundles_drop.php',
  data: {
   time_selected:value,
   networkType:networkType,
  },
  dataType : 'html',
  success: function (response) {
   // We get the element having id of display_info and put the response inside it
    $("#bundles").html(response);
  }
});

PHP：

    if( isset( $_POST['time_selected'] ) )
    {

     $duration_selected = $_POST['time_selected'];
     //$duration_selected = "day";
     $client_network =$_POST['networkType']
    }

当我收到AJAX帖子时，可以在第一行代码中完成回显变量。我的问题是稍后的代码行，变量会松散它们的值（我尝试在代码的不同部分回显，但只适用于前几行）。

如果我对它们进行硬编码并且不使用POST值，变量只保留它们的值。例如

$duration_selected = "day";

关于可能导致POST值丢失的任何想法？

完整的PHP代码：

<?php

include 'arrays.php';

global $netMap;
global $netArray;
global $cM;

global $contABB;

if( isset( $_POST['time_selected'] ) )
{

    $duration_selected = $_POST['time_selected'];
    //$duration_selected = "day";
    $client_net =$_POST['netType'];
    //$duration_selected = "ugmtn";




    $ds = $duration_selected;
    $cn = $client_net;


    $quantityOfCardsArray = array();
    $bundle_duration = array();
    $numberOfnets = count($netMap[$contABB]);
    $netNames = array();
    $net = array();
    $netNames = $netMap[$contABB];



    for($i=0;$i<$numberOfnets;$i++)
    {
            $thisnet=$netMap[$contABB][$i];
            $numD=count($cardMap[$contABB][$thisnet]);
            $bundle_duration = $cardMap[$contABB][$thisnet];
            $netName=$netArray[$contABB]["$thisnet"]["netName"]; 



            for($j=0;$j<$numD;$j++)
            {
                $cardIndex=$cardMap[$contABB]["$thisnet"]["$j"];
                //var_dump($priceInLocal=$netArray[$contABB]["$thisnet"][0]["$cardIndex"]);

            }
    }       
?>
                  <label id="bundlelbl"  for="bundle">Please select a bundle</label>
                  <select id="bundle" name="bundle" required>
<?php



    foreach($netNames as $index => $net){

        if($net == $client_net)
        {

            $net_bundle=$netArray[$contABB]["$net"];

            foreach($net_bundle as $value)
            {
                $value = (array) $value;

                foreach ($value as $time => $bundle_details)
                {
                    if($time == $duration_selected)
                    {
                            $detail_count = count($bundle_details);
                            $bundle_details = (array) $bundle_details;

                            //var_dump($bundle_details);

                            foreach($bundle_details as $data_value => $data_details)
                            {
                                $data_details = (array) $data_details;

                                echo "<option value='".  $data_details['Item'] ."'> ". $data_details['Item'] ." worth ". $data_details['pr'] . "</option>";


                            }

                    }
                }

            }

        }

    }
}
?>

  </select>


 <fieldset>
  <button type="submit">Submit</button>

我可以回复帖子的值直到

    ?>
                  <label id="bundlelbl"  for="bundle">Please select a bundle</label>
                  <select id="bundle" name="bundle" required>
<?php

超过该点，回声根本不显示。

解决：

我已经在if语句中放置了一个foreach循环，而对于我想要的它应该是另一种方式。感谢

Answer 1

在范围区域（在if语句中）声明变量时，只能在if中访问它们。之前声明它们并将它们设置为whithin，如下所示：

$duration_selected = '';
$client_network = '';

if( isset( $_POST['time_selected'] ) )
{
    $duration_selected = $_POST['time_selected'];
    //$duration_selected = "day";
    $client_network =$_POST['networkType'];
}

Answer 2

如果您在<DataTemplate> <Grid> <TextBox ContextMenuOpening="{Binding ??WHAT GOES HERE?? }" /> </Grid> </DataTemplate>块之外使用$duration_selected和$client_network，则除非至少执行一次，否则它将被取消定义。

因此，请确保访问前两个变量的代码在上述if( isset( $_POST['time_selected'] ) )块中运行。

示例：

if

由ajax
