$_SERVER['REQUEST_METHOD'] 返回 GET insted POST

Question

I create a form using post method like that:

  <form name="indexFormn" id="indexForm"  method="POST" action="page.php">
  <div class="AdminformDiv">
  <div class="errorbox">
      <?php
      if (!is_array($this->actionErrors)) {
        echo $this->actionErrors;
    }
    ?>
</div>
<div>
    <table border="0" cellpadding="0" cellspacing="0" style="width:700px">
        <tbody>
            <tr>
                <td style="width:128px">Amount</td>
                <td colspan="2">$ <?php echo $this->price;?> USD<td     style="width:270px">&nbsp;</td>
            </tr>
            <tr>

.....

but the problem is when I do "var_dump($_SERVER['REQUEST_METHOD']);" in my php code I get all time "GET" not "POST" and really I don't know why?

Answer 1

Basically most HTTP requests are GET requests. and $_SERVER['REQUEST_METHOD'] evaluates default GET method.

you can use if($_POST) to check if it's a POST. (That's the array with POST data in it. All pages have $_GET set, so if($_GET) won't work to tell if it's a GET)

when you submit your form then you will sure get POST method on "page.php". try to get method on this page and found.

Answer 2

I just had this problem using Codeigniter's MVC Framework. Here's what I discovered:

My Action attribute in my form did not include the "www" in front of my domain, but my actual URL needed the "www".

ie my form had action="https://mydomain/something" but if I went to that URL, I noticed my web host added the www to the beginning: https://www.mydomain/something . (I use DreamHost and it's a setting that I had picked)

I hope this is your issue as well - really frustrating to try and figure out, but once I got my action and actual URL to agree on the "www", my request method went from GET to POST.

Following on the answer by @Brian Stork, it is because of some sort of redirection that happens. The redirection can be because of the following:

• HTTPS/HTTP redirection. For example certbot activates this if you want. You can change this in your .conf file and then systemctl restart apache2
• Trailing Slash redirection.
• www subdomain redirection
• Other possible redirection?!

So check for all these. And if you are doing a bot like a Slack bot that sends requests to your app, check what is the exact url they are sending to avoid redirection.
