I need to insert all variables sent with post, they were checkboxes each representing an user.

If I use GET I get something like this:

?19=on&25=on&30=on

I need to insert the variables in the database.

How do I get all variables sent with POST? As an array or values separated with comas or something?

The variable $_POST is automatically populated.

Try var_dump($_POST); to see the contents.

You can access individual values like this: echo $_POST["name"];

This, of course, assumes your form is using the typical form encoding (i.e. enctype=”multipart/form-data”

If your post data is in another format (e.g. JSON or XML, you can do something like this:

$post = file_get_contents('php://input');

and $post will contain the raw data.

Assuming you're using the standard $_POST variable, you can test if a checkbox is checked like this:

if(isset($_POST['myCheckbox']) && $_POST['myCheckbox'] == 'Yes')
{
     ...
}

If you have an array of checkboxes (e.g.

<form action="myscript.php" method="post">
  <input type="checkbox" name="myCheckbox[]" value="A" />val1<br />
  <input type="checkbox" name="myCheckbox[]" value="B" />val2<br />
  <input type="checkbox" name="myCheckbox[]" value="C" />val3<br />
  <input type="checkbox" name="myCheckbox[]" value="D" />val4<br />
  <input type="checkbox" name="myCheckbox[]" value="E" />val5
  <input type="submit" name="Submit" value="Submit" />
</form>

Using [ ] in the checkbox name indicates that the selected values will be accessed by PHP script as an array. In this case $_POST['myCheckbox'] won't return a single string but will return an array consisting of all the values of the checkboxes that were checked.

For instance, if I checked all the boxes, $_POST['myCheckbox'] would be an array consisting of: {A, B, C, D, E}. Here's an example of how to retrieve the array of values and display them:

  $myboxes = $_POST['myCheckbox'];
  if(empty($myboxes))
  {
    echo("You didn't select any boxes.");
  }
  else
  {
    $i = count($myboxes);
    echo("You selected $i box(es): <br>");
    for($j = 0; $j < $i; $j++)
    {
      echo $myboxes[$j] . "<br>";
    }
  }

You can convince PHP's curl backend to stop doing the 100-continue-thing by setting an explicit request header:

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));

This way you can post a request however long you would ever want and curl will not do the dual phase post.

I've blogged about this nearly two years ago.

To make the post string correct, you must urlencode it. For example in description string you have spaces which break the post string.

Change

$post_items[] = $key . '=' . $value;

to

$post_items[] = $key . '=' . urlencode($value);

The following uses strpos() to check that the POST string begins with book_

foreach($_POST as $key => $value) {
    if (strpos($key, 'book_') === 0) {
        // value starts with book_
    }
}

You have to use headers config sections for headers, not the root level.

return new Client([
    'base_uri' => env('API_HOST'),
    'headers' => [
        'Accept' => 'application/json',
        'Authorization' => 'Bearer ' . $token,
        'Content-Type' => 'application/json',
    ],
]);
