Post Data to a Url in PHP

POST data to a URL in PHP

If you're looking to post data to a URL from PHP code itself (without using an html form) it can be done with curl. It will look like this:

$url = 'http://www.someurl.com';
$myvars = 'myvar1=' . $myvar1 . '&myvar2=' . $myvar2;

$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_POST, 1);
curl_setopt( $ch, CURLOPT_POSTFIELDS, $myvars);
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt( $ch, CURLOPT_HEADER, 0);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec( $ch );

This will send the post variables to the specified url, and what the page returns will be in $response.

Get values through post method from URL

As per your screenshot you are sending your empid through query parameter so you need to access that as follows

<?php
if (isset($_GET['empid'])) {
    echo $_GET['empid'];
}else{
    // else part
}

also for that you need to Request Url in Postman using GET method.

But as you have stated that you want to send empid through POST in postman, you have to send it through form-data in Postman and access it as $_POST["empid"];. following is the screenshot for your reference

else there is another option where you can send the POST data through body as row json and access it as

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

and $post will contain the raw data. And you can send it through postman as in following screenshot.

Post data to external URL

CURL should be enough to post data to different url (in this case xyz.com). Make sure the csrf is disabled since it's a POST request from different laravel app In Laravel 5, How to disable VerifycsrfToken middleware for specific route? if this still fail, check the log on laravel app

Send/Post Form Data to Url with PHP

http_build_query

(PHP 5, PHP 7) http_build_query — Generate URL-encoded query string

Example:

<?php
$data = array(
    'foo' => 'bar',
    'baz' => 'boom',
    'cow' => 'milk',
    'php' => 'hypertext processor'
);

echo http_build_query($data) . "\n";
echo http_build_query($data, '', '&');

?>

The above example will output:

foo=bar&baz=boom&cow=milk&php=hypertext+processor
foo=bar&baz=boom&cow=milk&php=hypertext+processor

The rest depends on your flow logic. To post to another script:

From this answer:

Possibly the easiest way to make PHP perform a POST request is to use
cURL, either as an extension or simply shelling out to another
process. Here's a post sample:

// where are we posting to?
$url = 'http://foo.com/script.php';

    // what post fields?
    $fields = array(
       'field1' => $field1,
       'field2' => $field2,
    );

    // build the urlencoded data
    $postvars = http_build_query($fields);

    // open connection
    $ch = curl_init();

    // set the url, number of POST vars, POST data
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, count($fields));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);

    // execute post
    $result = curl_exec($ch);

    // close connection
    curl_close($ch)

How to send POST data to external url and open the target url

I think you're looking for something like this: PHP Redirect with POST data

You will need a second page, that submits the post data to a completely different url.

How can I pass POST parameters in a URL?

You could use a form styled as a link. No JavaScript is required:

<form action="/do/stuff.php" method="post">
    <input type="hidden" name="user_id" value="123" />
    <button>Go to user 123</button>
</form>

CSS:

button {
    border: 0;
    padding: 0;
    display: inline;
    background: none;
    text-decoration: underline;
    color: blue;
}
button:hover {
    cursor: pointer;
}

How to read post url request from javascript in PHP

Ok I will explain with example,

If you want to get url parameter values to you have to use,

<script>
let my_variable='<?php echo $_GET['url_param_name'];?>';
</script>

above for more help and understanding. Now you want to send form data to php for processing as I got your answer.

This is sample form.

<form id="my_form" name"my_form" method="POST" onsubmit="return send();">
  First name:<br>
  <input type="text" name="first_name" value="Mickey">
  <br>
  Last name:<br>
  <input type="text" name="last_name" value="Mouse">
  <br><br>
  <input type="submit" value="Submit">
</form> 

To post above form I will use javascript function,

<script>
function send() {

    $.ajax
    ({
        type: 'POST',
        url: './path/your_php_file_where_form_data_processed.php',
        data:$('#my_form').serialize(),
        success: function () {
           // do what you need to do on succeess
        },
        error: function (x, e) {
            // for error handling
            if (x.status == 0) {
                console.log('You are offline!! -  Please Check Your Network.');
            } else if (x.status == 404) {
                console.log('Requested URL not found.');
            } else if (x.status == 500) {
                console.log('Internal Server Error.');
            } else if (e == 'parsererror') {
                console.log('Error. - Parsing JSON Request failed.');
            } else if (e == 'timeout') {
                console.log('Request Time out.');
            } else {
                console.log('Unknown Error. - ' + x.responseText);
            }
        }
    });
    return false;
}
</<script>

Now you need to check carefully your form element names. In php file. Let's look it.

<?php
//include_once './../../classes/Database.php'; import if you have database configurations
//session_start(); make sure to use sessions if your site using sessions

if(isset($_POST))
{
    var_dump($_POST); //this will echo your form inputed data.
    //if you want use one by one posted data
    echo $_POST['first_name'];
    echo $_POST['last_name'];
}
else
{
    echo 'Data not comes here';
}
?>

Thought this might help your task.

Send POST request with PHP

You can do a POST request using curl in PHP.

// initiate the curl request
$request = curl_init();

curl_setopt($request, CURLOPT_URL,"http://www.otherDomain.com/getdata");
curl_setopt($request, CURLOPT_POST, 1);
curl_setopt($request, CURLOPT_POSTFIELDS,
        "var1=value1&var2=value2");

// catch the response
curl_setopt($request, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($request);

curl_close ($request);

// do processing for the $response
