PHP - Moved: How Do You Send A Json Object To A Php File

Hello everyone.

please I have problem with printing out a value from inside an array of a nested json. ive tried several ways its always returns "index not define".
here is the code .

$valr= "https://ice3.com/api/v1/orderbook/ticker";    ////////////////////////////source

	 $valrGet =  file_get_contents($valr);
	 $valrD =  json_decode($valrGet, true);
	 $valrSell = ["ask"] ["price"];
                 

Here is the structure of the json from the source :

{"errors":false,"response":{"entities":[{"pair_id":3,"pair_name":"BTC\/ZAR","ask":{"price":"179382.54","amount":"0.05357142"},"bid":{"price":"177229.4286563","amount":"0.0011"}},{"pair_id":4,"pair_name":"BTC\/NGN","ask":{"price":"8890000.00","amount":"0.10"},"bid": 

my target is to  output  the value of  ("price") from "pair_name"   BTC\/ZAR

please help. Thanks in advance

Hi Everyone,

i need some help how can i save this jsonfile to the webserver? 

my code

       // Load initial values from JSON 'file'
    jsonfile = '[{"lane 1":"1","lane 2":"1","lane 3":"5","lane 4":"2"}]';
    var initialstate = JSON.parse(jsonfile);
    setLaneState("lane1",initialstate[0]['lane 1'])
    setLaneState("lane2",initialstate[0]['lane 2'])
    setLaneState("lane3",initialstate[0]['lane 3'])
    setLaneState("lane4",initialstate[0]['lane 4'])

 

Hi, As I am new to PHP and JSON my Interest in the field pushes me to know further. I have successfully parsed a JSON file:
{
"birthdays": [
"319507200" :"Kyle",
"1390435200" :"Noah",
"307843200" :"Carla"
]
} Using this PHP file:
<?php
$jsondata = file_get_contents("birthdays.json");
$json = json_decode($jsondata,true);
echo $json["birthdays"][0]['1390435200'];
?>

Now I would like to know how to display when Noah’s birthday is, in the form yyyy/MM/dd. Can an expert tell me how this would be done?

Thank you :-)

Hello
I am using curl to get a json file which can be located he (It's way too long to copy paste it): http://www.opap.gr/web/services/rs/betting/availableBetGames/sport/program/4100/0/sport-1.json?localeId=el_GR

After that i use json_decode to get the assosiative array.Till here everything seems ok.When i am using var_dump the characters inside the array are in Greek.After that i am using the following code:

Code: [Select]
class ArrayToXML {

public static function toXML( $data, $rootNodeName = 'ResultSet', &$xml=null ) {

    // turn off compatibility mode as simple xml throws a wobbly if you don't.
    if ( ini_get('zend.ze1_compatibility_mode') == 1 ) ini_set ( 'zend.ze1_compatibility_mode', 0 );
    if ( is_null( $xml ) ) //$xml = simplexml_load_string( "" );
        $xml = simplexml_load_string("<?xml version='1.0' encoding='UTF-8'?><$rootNodeName />");

    // loop through the data passed in.
    foreach( $data as $key => $value ) {

        $numeric = false;

        // no numeric keys in our xml please!
        if ( is_numeric( $key ) ) {
            $numeric = 1;
            $key = $rootNodeName;
        }

        // delete any char not allowed in XML element names
        `enter code here`$key = preg_replace('/[^a-z0-9\-\_\.\:]/i', '', $key);

        // if there is another array found recrusively call this function
        if ( is_array( $value ) ) {
            $node = ArrayToXML::isAssoc( $value ) || $numeric ? $xml->addChild( $key ) : $xml;

            // recrusive call.
            if ( $numeric ) $key = 'anon';
            ArrayToXML::toXml( $value, $key, $node );
        } else {

            // add single node.
            $value = htmlentities( $value );
            $xml->addChild( $key, $value );
        }
    }

    // pass back as XML
    return $xml->asXML();


}
public static function isAssoc( $array ) {
    return (is_array($array) && 0 !== count(array_diff_key($array, array_keys(array_keys($array)))));
}


And here comes the problem .All the greek characters inside the result are in some strange characters Code: [Select]
&Icirc;?&Icirc;?&Icirc;&yen;&Icirc;?&Icirc;?&Icirc;&iexcl;&Icirc;&copy;&Icirc;&pound;&Icirc;?&Icirc;? for example.I really don't know what am i doing wrong.I am really bad with encoding /decoding things .

Thanks in advance for your replies.

PS:I have also Code: [Select]
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> in the page i display the result but it doesnt help.

I actually have two parts to this post.  One which describes just my understanding on how a multipart request should look with a REST API and gives a little context, and the second how to actually implement it using Sympony and api-platform.

Part 1

Looking to simultaneously upload a file, some file meta data, and identifier of the uploading user to a REST API, and will do so using a multipart request.

Based on swagger, looks like the request should look something like the following:

POST /upload HTTP/1.1
Content-Length: 428
Content-Type: multipart/form-data; boundary=abcde12345
--abcde12345
Content-Disposition: form-data; name="id"
Content-Type: text/plain
123e4567-e89b-12d3-a456-426655440000
--abcde12345
Content-Disposition: form-data; name="address"
Content-Type: application/json
{
  "street": "3, Garden St",
  "city": "Hillsbery, UT"
}
--abcde12345
Content-Disposition: form-data; name="profileImage "; filename="image1.png"
Content-Type: application/octet-stream
{…file content…}
--abcde12345--

Background noise... The above example shows three parts which include the text ID, JSON address and octet-stream file.  Doing so doesn't make sense to me and I will probably just have two parts for the meta data JSON.  Note that potentially, I will be removing the user from the JSON payload and including it in some JWT header.  Also, showing resources as links such as /api/users/1 in the request and response JSON is new to me, but I guess makes sense.

Regardless, my meta data JSON will look like:

{
    "projectId": 1234,
    "documentDescription": "bla bla bla",
    "specification": "230903.2.4.D",
    "user": "/api/users/1"
}

and the response will look like:

{
    "projectId": 1234,
    "documentDescription": "bla bla bla",
    "specification": "230903.2.4.D",
    "uploadAt": "2021-01-27 08:41:17",
    "fileName": "pressuresensor.pdf".
    "user": "/api/users/1".
    "file": "/api/uplodaed_files/1234"
}

Am I somewhat going down the right path?

Part 2

Wow, should have looked into Sympony before now!  Entities, validation, the API, etc were a breeze.  Still confused with some of the "magic", but understanding what is under the hood more and more.

As stated initially, I am utilizing api-platform and am looking at api-platform's file-upload.

I guess the first question is whether my POST request with both the file and JSON meta data can be performed in a single request.

Per making-a-request-to-the-media_objects-endpoint:

Quote

Your /media_objects endpoint is now ready to receive a POST request with a file. This endpoint accepts standard multipart/form-data-encoded data, but not JSON data.

What?  Am I reading this correct?  Do I first need to make a multipart requests using either a standard HTML form or a XMLHttpRequest which just sends the file, receive the document locator, and then send a second request with the location and my meta data?

If so, I guess I have enough to go forward.  I would rather, however, perform the work in a single request.  My previous mentioned swagger multipart-requests shows both in the same request.  symfonycasts's api-uploads also describes doing so, but not with api-platform.  Is there a way to do so with api-platform?  Does it make sense to use api-platform for all other routes but then make a custom route for document with meta data uploads?  Any recommendations are much appreciated.

Thanks

I got some code to make a simple quiz, but I'm struggling to get it to work. I think the form and the following JavaScript code are set up correctly, but I'm running into problems with the PHP code at the end. I'm especially confused by the JSON reference at the very end; I don't have a clue what it means or what do do with it.   Does anyone know how to fix/complete this script?   On another note, why is it necessary to use JSON in the first place? Aren't the answers already provided in the PHP code (e.g. $answer1 = $_POST['A']?   Thanks.

I want to add a note field and a checkbox to my list/grid page and save this information to a json file using uomptrucknumber as the key. The note information will be information for the whole truck not by order. The check box will let them know that the truck is ready to have paper work printed.

I have not add the note field or checkbox because I did not want to start off wrong.

I use WYSIWYG Web Builder. They have a file upload option in their form wizard. But I don't want to upload the file. I only want the name of the selected file sent on submit. No matter what I try it keeps trying to send the file, or just sends a blank when I remove the var

I've looked though the code and this is the only parts I can find that have anything to do with the file upload. There will be more than one select B1-File, B2-File, B3-File etc....

I put one here.

I only want to get the file name that is selected not the file to be sent to the server. If someone knows of an easier way to use a file select/browse button and get the file name only and wouldn't mind sharing it. Thanks

I have been searching for a solution and have not been able to find the one.

Thanks
Bob
