Tutorial :Read POST request parameters properly in PHP for request more than 1450 B?



Question:

I receive POST request on my api.php script. The content red using this code:

$fp = fopen('php://stdin', 'r');  $all = "";  while($line = fgets($fp, 4096)) {       $all .= $line;   }  echo $all;  

looks like this:

------------V2ymHFg03ehbqgZCaKO6jy  Content-Disposition: form-data; name="intro"    O  ------------V2ymHFg03ehbqgZCaKO6jy  Content-Disposition: form-data; name="title"    T  ------------V2ymHFg03ehbqgZCaKO6jy  Content-Disposition: form-data; name="apiKey"    98d32fdsa  ------------V2ymHFg03ehbqgZCaKO6jy  Content-Disposition: form-data; name="method"    /media/add  ------------V2ymHFg03ehbqgZCaKO6jy  Content-Disposition: form-data; name="upload_field"; filename="original_filename.png"  Content-Type: image/png      ------------V2ymHFg03ehbqgZCaKO6jy--  

As you can see I get 4 parameters called intro, title, apiKey and method, and one file called original_filename.png with size of 1460 bytes.

Unfortunately, my $_POST array is empty. What is weird when orginal_filename.png is less than 1450 bytes $_POST contains all parameters, and stdin is empty.

I would like to be able to read these fields like normal human PHP being from $_POST.

What to do in order to read this POST request parameters properly from $_POST?


Solution:1

As I just read in the manual, raw post data is not available with enctype="multipart/form-data" but can you can also try with

$fp = fopen('php://stdin', 'rb');  

Please pay attention to the "b" flag.

Also, make sure that always_populate_post_data=On in your php.ini


Solution:2

Is there anything in the $_FILES variable?

Is there a MAX_FILE_SIZE element in the submitted form?

What are the values here?

echo 'post_max_size = ' . ini_get('post_max_size') . "\n";  echo 'upload_max_filesize = ' . ini_get('upload_max_filesize') . "\n";
