I am having an issue with PHP to JavaScript and then sorting. I have the following JS script
function sortby(param, data) {
switch (param) {
case "aplha":
console.log(data);
data.sort();
break;
}
}
The array this is passing is through json_encode and the array looks like so
Array ( [0] => Array ( [Name] => 123456 [Clean_Name] => 123456 [CreateDate] => 1372479841 ) [1] => Array ( [Name] => 123456 [Clean_Name] => 123456 [CreateDate] => 1372479841 ) )
However I get the above error when I try to pass it as data.sort(). Any ideas?
PHP arrays aren't js arrays, but JSON objects, so you can't have and array on your js code. However, there's a workaround, refer to this answer for more info.
Cheers
I think i found my issue however i dont know how to fix it. when i pass the variable with json_encode to the javascript function it passing it as a string so data[0] == [ ... what am i missing here
ALRIGHT wow i found my issue i am so sorry guys i am so dumb
<script>sortby('aplha', '<?=json_encode($teamList);?>');</script>
That was my old this is my new
<script>sortby('aplha', <?=json_encode($teamList);?>);</script>
It was the ' that was passing it incorrectly ... it works fine now I hit my desk so hard ...

I can't extract data from json that I got from an api.
I tried for hours, tried all kinds of formats. Read Stackoverflow threads like How do I extract data from JSON with PHP?, but I can't see what I am doing wrong.
This is the code so far:
$api_results = '{"status":"0000","data":{"opening_price":"6998000","closing_price":"7270000","min_price":"6750000","max_price":"7997000","average_price":"7188302.5804","units_traded":"78484.9241002","volume_1day":"78484.9241002","volume_7day":"335611.84181738","buy_price":"7268000","sell_price":"7274000","date":"1510563513031"}}';
$results = json_decode($api_results, true);
// Some variations I tried:
var_dump($results->status[1]);
var_dump($results->data[1]->opening_price);
var_dump($results["data"][1]["opening_price"]);
End result: NULL NULL NULL
What am I doing wrong?
Thanks for the answers! I will upvote the working ones. Seems I got confused in the formating!
<?php
$api_results = '{"status":"0000","data":{"opening_price":"6998000","closing_price":"7270000","min_price":"6750000","max_price":"7997000","average_price":"7188302.5804","units_traded":"78484.9241002","volume_1day":"78484.9241002","volume_7day":"335611.84181738","buy_price":"7268000","sell_price":"7274000","date":"1510563513031"}}';
$results = json_decode($api_results, true);
print_r($results['status']);
echo "</br>";
print_r($results['data']['opening_price']);
Try access your array that way.
The output is :
0000
6998000
Keep an eye for the nested arrays. You need to access their parent array first in order to get their values.
Have you read the documentation of json_decode() (or, at least, the accepted answer of the question you linked)? If you pass TRUE as the second argument to json_decode() (and there is no decent reason to not pass it) then it decodes the JSON to associative arrays and not objects.
The elements in a PHP array can be accessed using the square bracket syntax.
A simple call to print_r($results) tells its structure:
Array
(
[status] => 0000
[data] => Array
(
[opening_price] => 6998000
[closing_price] => 7270000
[min_price] => 6750000
[max_price] => 7997000
[average_price] => 7188302.5804
[units_traded] => 78484.9241002
[volume_1day] => 78484.9241002
[volume_7day] => 335611.84181738
[buy_price] => 7268000
[sell_price] => 7274000
[date] => 1510563513031
)
)
Now, accessing its items is a piece of cake:
echo($results['status']);
# 0000
echo($results['data']['opening_price']);
# 6998000
Remove true from json_decode so you will have object result like Demo
$results = json_decode($api_results);
var_dump($results->status);
var_dump($results->data->opening_price);
When you use json_decode with true the returned objects will be converted into associative arrays.
Use this code like i think work it fine..
<?php
$api_results = '{"status":"0000","data":{"opening_price":"6998000","closing_price":"7270000","min_price":"6750000","max_price":"7997000","average_price":"7188302.5804","units_traded":"78484.9241002","volume_1day":"78484.9241002","volume_7day":"335611.84181738","buy_price":"7268000","sell_price":"7274000","date":"1510563513031"}}';
$results = json_decode($api_results);
print_r($results);
var_dump($results->status);
$var = $results->data;
var_dump($var->opening_price);
?>
stdClass Object
(
[status] => 0000
[data] => stdClass Object
(
[opening_price] => 6998000
[closing_price] => 7270000
[min_price] => 6750000
[max_price] => 7997000
[average_price] => 7188302.5804
[units_traded] => 78484.9241002
[volume_1day] => 78484.9241002
[volume_7day] => 335611.84181738
[buy_price] => 7268000
[sell_price] => 7274000
[date] => 1510563513031
)
)
string(4) "0000"
string(7) "6998000"
Remove true from json_decode and try something like this:
var_dump($results->status);
var_dump($results->data->opening_price);
If you see {} it is refering to objects and [] indicates that it is an array. You're trying to show everything as if they were arrays
You have set the second parameter of json_decode() to true. that means the json will be converted to an array so you are not able to access the data using pointer -> (because it is not an object).
You may access the data like this:
var_dump($results['status'][0]);
var_dump($results['data'][0]['opening_price']);
P.S: Try var_dump($results) to see the exact data, so you know how to access each attribute.
I am using jQuery to convert form data to serialized form using:
var data = $('#frm').serialize();
In php I get this:
fiscalyear_id=4&category=Category+A&isgraph=on&Title=a&Value=a&Title=b&Value=b&category=Category+B&Title=c&Value=c&Title=d&Value=d&category=Category+C&Title=e&Value=e&Title=f&Value=f&data;=&csrf_check=9c288285b379701b27c3836091c00b04
And when I do:
parse_str($_POST['data'], $data);
pretty_print($data);
I get:
Array
(
[fiscalyear_id] => 4
[category] => Category C
[isgraph] => on
[Title] => f
[Value] => f
[data;] =>
[csrf_check] => 9c288285b379701b27c3836091c00b04
)
As can be seen, not all paramters are coming in array above. Does anyone have an idea what I am doing wrong ? Thanks for the help
parse_str parses the string in variable and you are getting it into array.
but duplicate array keys are not possible,
hence you are not getting all the values because they have the same key!
I am quite new with PHP and I am trying to read something form an API.
At the moment I use
$homepage = file_get_contents('http://www.site.com');
echo $homepage
This returns something which looks like this:
Array
(
[0] => Array
(
[name] => myname
[user_id] => 31232
)
[1] => Array
(
[name] => anothername
[user_id] => 23534
)
)
So here is what I want: I only want to read the [name] => x and leave the rest, so I tried a for loop within str_replace, but all I got were errors.
I hope someone is able to help me
Edit:
I just saw I could set is as a json text too, it returns something like
[{"name":"myname","user_id":"31232"},{"name":"anothername","user_id":"23534"}]
Edit2: Thank you Tuga, that was exactly what I was searching for :) I can't upvote, since my reputaion is below 15, is there another way for me to show your answer helped?
$array = json_decode($homepage); will return an array, then you can loop the array containing objects and use 'name' attribute :
foreach ($array as $obj) echo $obj->name;
I've searched a lot for this, and found several similar questions, but none quite address what I'm trying to accomplish.
I'm trying to write a code that will search a PHP (multi)multidimensional array to see which subarray contains the unique key value that I have. Then I would like it to return the value of a different key in that same object subarray.
$Arraytosearch = Array(
.
//various other subarrays
.
[fields] => Array (
.
.
.
//I don't know the number of the object subarray
[x] => PodioTextItemField Object (
[__attributes] => Array (
[field_id] => 37325091
[type] => text
[external_id] => id
[label] => ID
[values] => Array (
[0] => Array (
[value] => REF100019 ) )
[config] => Array (
[description] => [settings] => Array (
[size] => small )
[required] => [mapping] => [label] => ID [visible] => 1 [delta] => 2 ) )
.
.
.
//(and so on)
I'd like to write a function that will return "REF100019" by supplying the value of the field_id => 37325091.
Some things I have tried that I couldn't get to work:
foreach
and new RecursiveIterator although the tutorials I read weren't useful for my case here.
Even though the array looks complicated, I think it will be easy since I already have the field id of the parent array.
Thank you in advance for any guidance or sample codes that will work!
Background: This is a part of the response I get from Podio after submitting a request to their API. I just don't know how to take that response and get the piece I need (the ID) so that I can echo it for users).
EDIT: Thank you Orangepill and Barmar for the support. I tried your code. But was getting an error, which made me realize I hadn't given you the full array. I figured out how to get the Podio response to display in a more readable format (I was reading the full JSON response before from the Podio debug file which was super confusing), and figured out the full array is actually structured as I have shown below.
I then took your code and was able to figure out how to make it work for my scenario (see below). Very proud of myself considering I have never written any code before, but I couldn't have done it without your help! Thanks again!
$Arraytosearch = Array(
[items] => Array(
[0] => PodioItem Object(
[_attributes] => Array(
[fields] => Array (
[x] => PodioTextItemField Object (
[__attributes] => Array(
[field_id] => 37325091
[values] => Array(
[0] => Array(
[value] => REF100019 ) )
Note: For anyone who is new to programming like myself and wants the Podio response (or any JSON string) to display in a "pretty" readable format like above, use the code (from Display an array in a readable/hierarchical format thanks to Phenex):
print "<pre>";
print_r($Arraytoformat);
print "</pre>";
And finally, the full code I used (using Orangepill's answer below) which searches the objects and arrays and gives me what I have been searching for for days now is as follows:
$Arraytosearch = PodioItem::filter(APP_ID, $filterParams);
$fieldID = 37325091;
function getFirstValueByFieldId($fieldId, $Arraytosearch){
foreach($Arraytosearch["items"][0]->__attributes["fields"] as $textitem){
if ($textitem->__attributes["field_id"] == $fieldId){
return $textitem->__attributes["values"][0]["value"];
}}}
$refID = getFirstValueByFieldId($fieldID, $Arraytosearch);
The podio-php library has built-in methods that handle all this for you. There's no need to mess with the __attributes property yourself.
You can see a bunch of examples at https://github.com/podio/podio-php/blob/master/examples/items.php
In your case:
// Get item collection
$itemCollection = PodioItem::filter(APP_ID, $filterParams);
$fieldID = 37325091;
foreach ($itemCollection['items'] as $item) {
// Get the field from the item
$field = $item->field($fieldID);
// Now you can print the value of that field
print $field->humanized_value;
// Or if you don't want to have the content sanitized:
print $field->values[0]['value'];
}
There is a lot of ways to skin this cat... this is probably the most straight forward
function getFirstValueByFieldId($fieldId, $Arraytosearch){
foreach($Arraytosearch["fields"] as $textitem){
if ($textitem->__attributes["field_id"] == $fieldId){
return $textitems->__attributes["values"][0]["value"];
}
}
}
to Use in your case would be
echo getFirstValueByFieldId("37325091", $Arraytosearch);
Basically it walks the elements in the fields array and returns the value in the first associated value in the values array where field_id is equal to the parameter of the function.
Array
(
[0] => Array
(
[price_id] => 1
[website_id] => 0
[all_groups] => 1
[cust_group] => 32000
[price_qty] => 2
[price] => 90.0000
)
[1] => Array
(
[price_id] => 2
[website_id] => 0
[all_groups] => 1
[cust_group] => 32000
[price_qty] => 5
[price] => 80.0000
)
.......
)
the array element maybe one or two or more, if i want to pass [price_qty] and [price] value to the jquery code. how should i do? could someone make me an example. thank you
you should consider using JSON strings in order to use key based arrays in JavaScript.
http://php.net/json
json_encode your php arrays to json
Use json_encode to convert your php array to json :)
A possible solution is to convert php array structures into JSON before passing the data to the client.
Have a look at php json.
And also have a look at this post.
Try with Json:
json_encode($array);
This will encode the array into a json object, that is friendly with javascript (and Jquery).
If you are passing it through an ajax request just echo it in the php and return that as response.
If it's in the same script you could do:
$object = json_encode($array);
echo "var myObject = $object;";
And for accessing the information in javascript/jquery you would do:
alert(myObject[0].price_id);
you use myObject[0] to access positions as in php arrays, and myObject[0].name to access what would be associative array key in an array.
For more information visit json documentation page
Well while you ask to move from [php]array to [javascript]array, this is how to. You should ue json_encode how the previous answer said, but in you javascript you can use the following code to convert a json into an array:
function json2Array = function(json){
var a = [];
for(var o in json){
a.push(json[o]);
}
return a;
}
var myArray = json2Array(youPhpJsonEncode);
and you will have your array in javascript
