JSON/PHP

[dtek516]

Need to retrieve values from ajax object, server-side and I’ve spent days trying to figure this out. Ajax/JS Newbie newbie.

Here’s my js:

question1 = {testNumber : 20, Answer: 3, timeComplete: 00:05:37}
question2 = {etc, etc, etc}

allQuestions = {q1:question1, q2:question2, q3:question3, q4:question4, q5:question5, q6:question6};

                    $.ajax({

                         type: 'POST',

                         url: allURL, 

                         data: {"questions" : JSON.stringify(allQuestions)},


                         success: function( resp ){

                            $('#allanswers').append( resp );


                         },
                         error: function( xhr, status, errorThrown ) {
                            alert( "Sorry, there was a problem!" );
                            console.log( "Error: " + errorThrown );
                            console.log( "Status: " + status );
                            console.dir( xhr );
                        },

                    });     

my php:

<?php
if (isset($_POST[“questions”])) {
$questions = $_POST[“questions”];

    // Decode our JSON into PHP objects we can use
    $allQuestions = json_encode( $questions, true);

}

?>

when I print_f, I get:

“{\\”q1\\”:{\\”testNumber\\”:\\”31\\”,\\”Answer\\”:\\”1\\”,\\”timeComplete\\”:\\”00:05:49\\”},\\”q2\\”:{\\”testNumber\\”:\\”30\\”,\\”Answer\\”:\\”2\\”,\\”timeComplete\\”:\\”00:05:75\\”},\\”q3\\”:{\\”testNumber\\”:\\”29\\”,\\”Answer\\”:\\”2\\”,\\”timeComplete\\”:\\”00:05:43\\”},\\”q4\\”:{\\”testNumber\\”:\\”28\\”,\\”Answer\\”:\\”2\\”,\\”timeComplete\\”:\\”00:05:43\\”},\\”q5\\”:{\\”testNumber\\”:\\”27\\”,\\”Answer\\”:\\”2\\”,\\”timeComplete\\”:\\”00:05:29\\”},\\”q6\\”:{\\”testNumber\\”:\\”27\\”,\\”Answer\\”:\\”2\\”,\\”timeComplete\\”:\\”00:05:67\\”}}”

I’m so frustrated and spinning my wheels, and my boss is pissed. Can someone please point me in the right direction?

$allQuestions = json_encode( $questions, true);

You’re encoding the already-encoded JSON, so now, it’s double-encoded. That’s exactly what you see when you print it.

…perhaps you mean to use json_decode?

Oops, I think that just got switched in my struggle. Lol. Thanks for pointing it out.

How do I access those array values? I tried echo $ allQuestions [0][0];

Also, echo $ allQuestions [0][‘testNumber’];
as an example.

Still nothing. I’m sorry to sound so desperate..but I’ve searched and switched, over and over.

echo $allQuestions[0]['testNumber']; as an example.

Looking at your code above, I would not expect $allQuestions[0]['testNumber'] to exist. You seem to be using a “q{number}” naming scheme (i.e., $allQuestions['q1']['testNumber']).

If you’re not sure about the structure of your array, inspect it:

print "<pre>";
var_dump( $allQuestions );

I do, i believe my issue to be that i combined the objects, and now it’s a bit too deep.

so, the original objects being:

$question1{testNumber, answer, timeComplete};

question2{ etc…}

were combined into $allQuestions{ q1:question1, q2:question2….}
so that i could send it off to my php, but now im having trouble accessing them.

Believe me, I’m all about learning new things on my own, however, this seems like I’m just missing something and could really use the answer.

As I had mentioned, i set up my ajax as POST, and my object as

data: {“questions” : JSON.stringify(allQuestions)}

because of my notation, am i accessing these array items in the same notation after the decode? such as $passedQuestions[q1][answer]? so something to that effect?

See my last comment.
Judging by the code you’ve posted, I would expect to find $allQuestions['q1']['testNumber'], et.al..

More importantly,

re-read my comment about using var_dump.
