Noob cant get alprd to work

[Axryx]

So i have everything setup for alprd.

Config file:

; This configuration file overrides the default values specified

; in /usr/share/openalpr/config/alprd.defaults.conf

[daemon]

; Declare each stream on a separate line

; each unique stream should be defined as stream = [url]

stream = http://192.168.0.6:8080/current0.mjpg

site_id = site-name

store_plates = 0

store_plates_location = /var/www/html/plates/

; upload address is the destination to POST to

upload_data = 1

upload_address = http://192.168.0.46/detect.php

country = eu

detect.php:

<?php

foreach(json_decode(file_get_contents('php://input')) as $Detect)

        {

                $Detect["uuid"];//: "e11e0acc-6aaf-4817-9299-9e6773043b8e"

                $Detect["camera_id"];//: 1,

                $Detect["site_id"];//: "watchtower-hq",

                $Detect["img_width"];//: 640,

                $Detect["img_height"];//: 480,

                $Detect["epoch_time"];//: 1402161050,

                $Detect["processing_time_ms"];//: 138.669163,

                foreach($Detect["results"] as $Plate)

                {

                        echo $Plate["plate"];

                }

        }

?>

No number plate detected.

And when i go to http://192.168.0.46/detect.php even when a numberplate is detected in console i see nothing. 

Please help i need this asap

The daemon will POST your data to that address.  I'm not sure if that code is the right way to pull POST data...

Perhaps try starting with var_dump of the HTTP request to see if it's making it:

var_dump($_REQUEST);

You can also run wireshark or tcpdump to see the packets send between those servers just to verify that it's being sent.

SO thanks for your reply but when i run

var_dump($_REQUEST);

i just get 

array(0) { }

How can i fix this

Thanks

The ALPR daemon POSTs to a web server.  In your case, your PHP script would need to be running as a web server.

If you just want data from OpenALPR, you may be better off pulling from the beanstalkd queue.  it's named alprd.  Beanstalkd has client libraries in PHP:

More doc on alprd is available here:
