Receive Json Post With PHP

PHP Get JSON POST Data

The following is working for me now:

$inputJSON = file_get_contents('php://input');
$input= json_decode( $inputJSON ); 

I think my issue was using:

$input= json_decode( $inputJSON, TRUE ); 

instead of just:

$input= json_decode( $inputJSON ); 

Reading JSON POST using PHP

You have empty $_POST. If your web-server wants see data in json-format you need to read the raw input and then parse it with JSON decode.

You need something like that:

$json = file_get_contents('php://input');
$obj = json_decode($json);

Also you have wrong code for testing JSON-communication...

CURLOPT_POSTFIELDS tells curl to encode your parameters as application/x-www-form-urlencoded. You need JSON-string here.

UPDATE

Your php code for test page should be like that:

$data_string = json_encode($data);

$ch = curl_init('http://webservice.local/');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: ' . strlen($data_string))
);

$result = curl_exec($ch);
$result = json_decode($result);
var_dump($result);

Also on your web-service page you should remove one of the lines header('Content-type: application/json');. It must be called only once.

Receive JSON POST in PHP with ENTER in one of the field value

You're correct that in PHP7+, a literal tab or newline is going to cause the json parsing to fail. file_get_contents("php://input") returns a single string so I see no reason why you couldn't just filter that before you attempt to parse it. But maybe I'm missing something.

//Catch Unix OR DOS line endings, but not both
$filter = Array("\n","\n\r");
$replace = " ";
$cleanJSON = str_replace($filter, $replace, file_get_contents("php://input");
$data = json_decode($cleanJSON));

I want to point out that after this point, your code is referencing a variable that does not exist: $jason_value

$crm_id = $jason_value->data->crmId;
$descriptions = $jason_value->data->descriptions;

To reference properties of the object you just created, go directly to $data:

$crm_id = $data->crmId;
$descriptions = $data->descriptions;

I expect that you'd want to replace the newline with a space but you may just want an empty string if what you're actually encountering has a space before the newline but that's impossible to tell from what we have.

PHP Receive JSON POST Data

You've got a couple of problems here. First, you need to pass true as the second parameter to json_decode in order to get an associative array instead of a stdClass. Then, when you're iterating the results, you don't need the $key, and the $value is each entry in the results array (each "row"). Try running this to see what's going on:

<?php
$json = <<<JSON
[{"field":"_USERNAME","value":""},
{"field":"_PASSWORD","value":""},
{"field":"_TOKEN","value":""},
{"field":"_CODE","value":"L77H4XD6ZA"},
{"field":"_SUBMITTEDDATE","value":"2017.08.16.01.54"},
{"field":"_SUBMITTEDDATEEXT","value":"2017.08.16.01.54.39.610"},
{"field":"_EDITEDDATE","value":"2017.08.16.01.55"},
{"field":"_SEQUENTIALID","value":"39a1cad9-2582-e711-9477-06c7814985cc"},
{"field":"_COMPLETETYPE","value":"Complete"},
{"field":"_LANGUAGE","value":"en"},
{"field":"_TOTALTIME","value":"12.59"},{"field":"_LINKURL","value":"http%3a%2f%2fsurv.blah.com%2ftest3%3fusr%3dL77H4XD6ZA"},
{"field":"GENDER","value":"TEXT%3aFemale%3bVALUE%3a2"},
{"field":"AGE","value":"TEXT%3a40%2b-%2b44%3bVALUE%3a6"},
{"field":"STATE","value":"TEXT%3aVIC%3bVALUE%3a2"},
{"field":"END_CHC","value":"TEXT%3aComplete%3bVALUE%3a2"},
{"field":"D2H","value":""},
{"field":"D2V","value":""},
{"field":"PCODE","value":""},
{"field":"PSTATE","value":""},
{"field":"PREGION","value":""},
{"field":"STATEREGION","value":""},
{"field":"TEST1","value":""}]
JSON;

$obj = json_decode($json, true);

foreach($obj as $currTuple)
{
    echo $currTuple['field'].':'.urldecode($currTuple['value'])."\n";
}

Also some of the results are url encoded, so you'll probably want to decode that before persisting.
