How to generate a pass from 2 different json_encodes - php

Question

I use this method to generate a pass: public function setJSON($JSON) {
if(json_decode($JSON) !== false) {
$this->JSON = $JSON;
return true;
}
$this->sError = 'This is not a JSON string.';
return false;
}
I call this method to generate pass by: $pass->setJSON('{
"passTypeIdentifier": "'.$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%)"
},
.....................
]
}');
But now I don't write those locations statically and I get those data from database by : $query5 = mysql_query("select * from company");
while ($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>
There is no error when I test for updating pass, but I cannot see the pass on lock screen like before. Thus it means that I not yet include those locations to the pass. What should I change ? Is it the problem of method setJSON ? If I do like this, how can I combine these 2 jsons to become together ?

Rather than constructing the JSON directly, construct an array first, then transform it into 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
),
)
);
Then transform the array into JSON:
$pass->setJSON(json_encode($pass_data));
