i passed a json_encoded array to javascript. Now i would like to acces that array to get the different elemtnts.
i print it out in the console.log() and i get this array:
array(1) {
[16]=>
array(2) {
[3488]=>
array(1) {
[0]=>
array(2) {
["article_no_internal"]=>
string(6) "999184"
["article_name_internal"]=>
string(29) "Geschenkbox Kerzenschein 2011"
}
}
[2615]=>
array(1) {
[0]=>
array(2) {
["article_no_internal"]=>
string(6) "700469"
["article_name_internal"]=>
string(29) "Hotelscheck RomantischeTagef2"
}
}
}
}
This is about right. How can i access the article_name of the second array, with the ID 2615?
found a related question here reading a jsone object, hope for some better explebation or answer. Thanks.
EDIT:
As it seems i made a mistake, i showed a php var_dump in the console. When i try to show the javascript array in the console i get undefined.
Since JSON means "JavaScript Object Notation" you don't need to do anything to access the object's items.
For example you can access:
jsonObject[2615][0]["article_name_internal"]
if this object is String, use eval to convert the string to a JavaScript object and access the items in the same way with the previous example.
var jsonObject = eval(jsonstring);
jsonObject[2615][0]["article_name_internal"]

I'm sending this JSON:
[{"tipo":""},{"activo":""},{"titulo":"Servicoasd B"},{"texto":"asdasdasd"}]
to a php file via post method.
There, i do
$obj = json_decode($_POST['sentJson']);
However, I seem to be unable to access the elements of the JSON.
var_dump(($obj));
Shows the object:
array(4) {
[0]=>
object(stdClass)#2 (1) {
["tipo"]=>
string(0) ""
}
[1]=>
object(stdClass)#3 (1) {
["activo"]=>
string(0) ""
}
[2]=>
object(stdClass)#4 (1) {
["titulo"]=>
string(9) "Servico B"
}
[3]=>
object(stdClass)#5 (1) {
["texto"]=>
string(6) "asdasd"
}
}
But if I try
$obj['texto'];
$obj->{'texto'};
$obj[0]['texto'];
$obj[0];
It shows "undefined index texto" or "trying to get property of non object in" and the last one "Object of class stdClass could not be converted to string in". I'm very new to PHP, but still I can't seem to notice what I'm doing wrong. Any help would be appreciated.
Your JSON is a serialized array of four completely different objects, so when you run json_decode, that's what you get: an array.
If you want to access your objects inside that array, access them like you would any other indexed array:
$list = json_decode(...);
foreach($list as $obj) {
var_dump($obj)
}
Or target them explicitly using plain old numerical access.
$list = json_decode(...);
$last = $list[3];
$text = $last->texto;
But really the question you should be asking is why this is the JSON you get. An array with completely different objects at each position is terrible data, and should be fixed.
I'm working on a php magento script which have a array variable for store some script urls.
array variable $items['js']
var_dump
array(1) {
[""]=>
array(17) {
["prototype/prototype.js"]=>
string(22) "prototype/prototype.js"
["varien/form.js"]=>
string(14) "varien/form.js"
["mage/translate.js"]=>
string(17) "mage/translate.js"
["mage/cookies.js"]=>
string(15) "mage/cookies.js"
["wyomind/layer/native.history.js"]=>
string(31) "wyomind/layer/native.history.js"
["varien/weee.js"]=>
string(14) "varien/weee.js"
["geissweb/vatvalidation-min.js"]=>
string(29) "geissweb/vatvalidation-min.js"
}
}
I tried to access the "geissweb/vatvalidation-min.js" value like this
$items['js']['geissweb/vatvalidation-min.js']
but it return empty value, is there have a way to get that value without use foreach or for loop. Thank You
Your index is '', shown by...
array(1) {
[""]=>
so you need to use...
$items['js']['']['geissweb/vatvalidation-min.js']
You have your variable $items['js'] as an array of arrays what your looking for without a foreach is this :
$items['js'][0]['geissweb/vatvalidation-min.js'] is not valid
after tests
$items['js'][""]['geissweb/vatvalidation-min.js'] is valid.
I have an api wrapper i am using that returns something like this
object(stdClass)#7 (1) {
[0]=>
object(stdClass)#6 (2) {
["contactId"]=>
string(2) "nV"
["email"]=>
string(31) "email#domain.com"
}
}
how do i access the email part with PHP
Cast your API returned data to an array.
For example you are saving API returned data in $result variable. Cast it to an array.
$arrayResult = (array) $result;
echo $arrayResult[0]->email;
Try this.
I get a returned result from an API in stdClass format. I don't know anything about this type of data. So here it looks like:
object(stdClass)#41 (1) {
["return"]=>
object(stdClass)#42 (7) {
["afterPayOrderReference"]=> string(32) "d4ab78df6ab2ef84194dd1c1d66240b8"
["checksum"]=> string(32) "4f8826a99e9c0a67e578d04b6a625117"
["resultId"]=> int(0)
["statusCode"]=> string(1) "A"
["timestampIn"]=> float(1408533108515)
["timestampOut"]=> float(1408533113616)
["transactionId"]=> int(129525)
}
}
What I need is retrieving the statusCode value. I tried doing like in a post I read:
$array = (array) $stringResult;
$array[0]->statusCode;
But it didn't work. Please, someone explain to me in the simplest way because it's really new to me. Thanks.
Object properties are accessed with the -> operator. Just do:
echo $stringResult->return->statusCode;
If you wanted an array you would access like this since the array contains an object:
$array = (array)$stringResult;
echo $array['return']->statusCode;
Its an object array, so just as you call the array element,
echo $stringResult["return"]->statusCode
I'm trying to extract a value from a JSON string that's in my program. The output of var_dump($obj); is this:
object(stdClass)#1 (1) {
["BTC"]=>
object(stdClass)#2 (2) {
["value"]=>
float(403.645)
["currency"]=>
string(3) "GBP"
}
}
What I want to access is the value (currently 403.645 in this example), but I can't work out how to do it.
I've tried $obj->value and other combinations, but get nowhere; it appears to me that this is an object inside an object and as a result I can't find out how to access it. Any help would be appreciated!
