Question

i wanna to get a json file from a php page but my code doesn't work, what's wrong?

my php page is

header('Content-type: application/json');
$jsonstart="{'files' : [";
$jsonend="]}";
$content="{'firstname' : '".$_GET['name']."' , 'lastname' : 'izadi'}";
$jsonfile=$jsonstart.$content.$jsonend;

my ajax code is

 $(document).ready(function(){
   $.getJSON("getfilesinfo.php?name=afshin", function(data){
         alert(); 
         var test=JSON.parse(data);
         alert("Data: " + test.files[1].firstname + "\nStatus: " + status);
     });  
});

Answer 1

You must use json_encode() in your php file like this.

<?php
header('Content-type: application/json');

$array = array(
    'firstname' => $_GET['name'],
    'lastname' => 'izadi'
);

echo json_encode($array);

exit;

Answer 2

try this cleaner code using json_encode

<?php
header('Content-type: application/json');

$array = array(
    'firstname' => $_GET['name'],
    'lastname' => 'izadi'
);

echo json_encode(array('files'=>array($array)));

js:

 $(document).ready(function(){
   $.getJSON("getfilesinfo.php?name=afshin", function(test){
         alert("Data: " + test.files[1].firstname );
     });  
});
