如何产生2个不同json_encodes

Question

我用这个方法来产生一通一通：

 public function setJSON($JSON) { 
    if(json_decode($JSON) !== false) { 
     $this->JSON = $JSON; 
     return true; 
    } 
    $this->sError = 'This is not a JSON string.'; 
    return false; 
    } 

我把这种方法生成的通：

$pass->setJSON('{ 
    "passTypeIdentifier": "'.$passTypeID.'", 
    "formatVersion": 1, 
    .............. 
"barcode": { 
     "altText" : "'.$alt.'", 
     "format" : "PKBarcodeFormatPDF417", 
     "message": "Member-Card", 
     "messageEncoding": "iso-8859-1", 
     "changeMessage" : "This pass now has altText %@ !" 
     }, 
"locations" : [ 
    { 
     "longitude" : 104.89529371261597, 
     "latitude" : 11.576150037278605, 
     "relevantText": "CamMob (dis. 1%)" 
    }, 
    ..................... 
] 
    }'); 

但现在我不写静态的位置，我也得到那些来自数据库的数据通过：

$query5 = mysql_query("select * from company"); 
    while ($row5 = mysql_fetch_array($query5)){ 
     $companyName = $row5['relevantTextName']; 
     $discount = $row5['relevantTextDiscount']; 
     $long = $row5['longitute']; 
     $lat = $row5['latitute']; 
     $link = $row5['link'];
 

$location['locations'][] = array("longitute" => $long, "latitute" => $lat, "relevantText" => $companyName." (" . $discount. "%)"); 
} 
$jsonString = json_encode($location) ; 

error_log("Locations: ".$jsonString,0); 
$pass->setJSON($jsonString); 

$pass->setJSON('{ 
"passTypeIdentifier": "'.$passTypeID.'", 

    "barcode": { 
    "altText" : "'.$alt.'", 
    "format" : "PKBarcodeFormatPDF417", 
    "message": "Member-Card", 
    "messageEncoding": "iso-8859-1", 
    "changeMessage" : "This pass now has altText %@ !" 
    }  
}');</pre> 

当我测试更新通行证时没有错误，但我看不到以前像锁定屏幕上的通行证。因此这意味着我尚未将这些位置包含在通行证中。我应该改变什么？它是setJSON方法的问题吗？如果我喜欢这样，我怎么能把这两个jsons结合在一起？

不是直接构建JSON，而是先构造一个数组，然后将其转换为JSON。

$pass_data = array("passTypeIdentifier" => $passTypeID, 
        "formatVersion" => 1, 
        "barcode" => array (
             "altText" => $alt, 
             "format" => "PKBarcodeFormatPDF417", 
             "message" => "Member-Card", 
             "messageEncoding" => "utf-8", // use UTF8 in case you want to encode Khmer or other non ASCII 
             "changeMessage" => "This pass now has altText %@ !" 
            ), 
        "locations" => $locationsArray, 
        "organizationName" => "Digi club card", 
        "description" => "Membership card", 
        "logoText" => "Digiclub", 
        "foregroundColor" => "rgb(0,0,0)", 
        "backgroundColor" => "rgb(211,211,211)", 
        "generic" => array (
          "headerFields" => array(
             array ("key" => "Status", 
               "label" => " ", 
               "value" => "Membership card" 
              ), 
             ), 
          "primaryFields" => array(
             array ("key" => "Name", 
               "value" => $memberName, 
              ), 
             ), 

          "secondaryFields" => array(
             // Secondary Field data 
             ), 

          "auxiliaryFields" => array(
             // Auxiliary Field data 
             ), 

          "backFields" => array(
             // Backfiels Field data 
             ), 
          ) 
        ); 

则数组转换成JSON：

$pass->setJSON(json_encode($pass_data));
