I have the following JSON string:
[{\"index\":0,\"date\":\" 20120030\",\"title\":\"afsa\"}]
And I need to get out the contents into a variable foreach one.
This is how it is picked up so far...
$json_data_string = $_POST['hidden_event']; // sanitize however
$array_data = json_decode($json_data_string);
echo $json_data_string;
I need to be able to echo each out. for example:
foreach {
echo $date;
echo $title;
}
Thanks in advance for any help.
I think if you want to use this using jquery you will do like this:-
var recordList = [{\"index\":0,\"date\":\" 20120030\",\"title\":\"afsa\"}]
jQuery.each(recordList, function()
{
alert(this.Name); // For example
alert(this.date); // For example
});
or like this:-
$.ajax({
type: "POST",
url: URL,
cache:false,
data: values,
dataType:'json',
success: function(json)
{
var date = json.date;
alert(date);
} // end success function
});
foreach($array_data as $data) {
echo $data->date, PHP_EOL;
echo $data->title, PHP_EOL;
}
echo $data->date . "\n"; and echo $data->title . "\n";
PHP_EOL is useful for log files or command line integration, but in this case where you're outputting it to the user, it wouldn't make a difference, as no matter whether you use \n or \r\n (dependent on whether the server is Windows or *nix), it would only be visible to the user unless a <pre> tag was used, and if the <pre> tag was used then both \n and \r\n will be substituted with a single new line (at least on my Chrome 18). Still, you're right, you might as well use PHP_EOL, but just remember that it won't make any difference in the case of output.You can use extract function on $array_data to get variables.
$array_data = json_decode($json_data_string);
extract($array_data);
echo $index;
echo $date;
Try var_dump (http://php.net/manual/en/function.var-dump.php), that will give you idea how $array_data is structured. If you do this
echo '<pre>';
var_dump($array_data);
echo '</pre>';
you get even prettier dump. From there it's farily easy to see how to echo variables.
hidden_event). It's tricky to sort out what happens in JSON requests, try var_dumping whole $_POST (and maybe also $_GET). Are you sure that you are using JSON POST method, and not GET? If you have firefox, try using firebug, that gives you idea what happens with these "hidden" JSON requests.json_decode behaves, and now thinking if $_POST['hidden_event'] would not exists you would find your problem earlier, so I stand corrected. Try what mathroc suggested, and you probably find your problem there. When ever I cannot use normal debug tools, I find var_dump very easy way to see what is going on.$json_string = $_POST['hidden_event'];
$array = json_decode ( $json_data_string);
extract ($array);
echo $date;
echo $title;
