transfer of data on URL click - php

Question

I am new to JSON data transfer. I want to make a user click on a link in a webpage and that should redirect the user to another page with his login credentials in the url and display it there. Now this all I want to send and receive through JSON . I am working on PHP environment. I am adding a short code on which I am working but not knowing how to proceed exactly.
send.php
<?php
$data = '{ "user" : [
{ "email" : "xyz#gmail.com",
"password" : "xyz#123",
"employee_id" : 77
}
]
} ';
$url_send ="http://localhost/cwmsbi/recieve.php";
$str_data = json_encode($data);
function sendPostData($url_send, $post){
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS,$post);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($post))
);
$result = curl_exec($ch);
curl_close($ch); // Seems like good practice
return $result;
}
echo " " . sendPostData($url_send, $str_data);
?>
And receive.php
<?php
$json_input_data=json_decode(file_get_contents('php://input'),TRUE);
print_r( $json_input_data);
?>
Now when I am running send.php on my localhost, it displays the data on same page but does not goes to recieve.php.
How this can be achieved? I am curious and in need of this too. How can I run a JSON file and where should i obtain results? Your guidance will be immensely useful to me right now.

Answer 1

First of all i see you are json encoding $data two times (as when it gets defines it is already a json string and then you do $str_data = json_encode($data);).
If you want to achive the change of location with post data too, you can't use curl
(POST data and redirect user by PHP CURL - read this question for further infos) - and i don't think you can do it by php only.
If i was trying to achive what you're trying to achive (and i would never make a page to show login password to users - as it is bad practice to show a password, even in emails), i suggest to set the json string into $_SESSION variable in send.php and redirect with header("Location: http://localhost/cwmsbi/recieve.php") where you get the json data from $_SESSION variable and you print it.
I did not make an example as i think this one perfectly suites you:

Extra hint: even if placing the password in php $_SESSION variable is better than put it in post request, remember you are doing bad practice and at least remember to empty out that json string in $_SESSION variable after you print it.
e.g.:
unset($_SESSION['user_data']);
