php creating an api post problem
Hi
it is the first time i learn how to write an api. i have the folder structure of: apihub/v1/api.php
the GET part works: i get all the customers and a customer according to an id. i have issue with POST variables.
i read that instead of reading POST array one should use : file_get_contents("php://i
so i have this code:
and when i use the chrome extension i get NULL, but if i don't use the json_decode i so get the json string. what am i missing here? and how can i use that, cause according to it i want to write the query to the database.
![post data string]()
![getting null with the decode]()
best regards

Have you tried var_dump($_POST)? Or maybe var-dump($_REQUEST)? The latter should also include the $_GET and $_COOKIE information.

hi
gr8gonzo good explanation, yet with your separation, i still get NULL. and with the chrome browser extention i do use: application/x-www-form-url
ray: i attach the image of bar_dump post. the values are there. so somehow the json_decode return NULL and i don't understand why.
should i just use regular post array, in order to query the database? therefore skeep the decode or totally the file_get_contents? again, the question is why i get the NULL.

json_decode return NULL and i don't understand why.PHP has ways of discerning the errors in JSON strings.
It would be easier for us to help you if you would post the test data and code snippets instead of pictures of test data and code! We could use copy / paste to ensure we were working with the same test data set you're using. Please have a look at var_export().
Here is my teaching example showing how to decode json strings and detect errors, if any.
<?php // demo/json_decode_show_errors.php
/**
* JSON stands for JavaScript Object Notation
* http://json.org/
*
* JSON support in PHP does not have very good error handling
*
* JSON strings are all UTF-8
* http://www.experts-exchange.com/articles/11880/Unicode-PHP-and-Character-Collisions.html
*
* PHP man page references

Did you try the parse_str line I mentioned? Again, your screenshots show that you are posting form content, not JSON, so try:
$raw = file_get_contents("php://i
parse_str($raw, $_POST);
var_dump($raw);
var_dump($_POST);
$raw = file_get_contents("php://i
parse_str($raw, $_POST);
var_dump($raw);
var_dump($_POST);

good explanation and code example
So the issue is resolved? What was the fix?
