I am trying to call a python script from my PHP page but no output is being delivered. Is there any error in code ?
<?php
include('main.php');
$lat = $_POST['lt'];
$lon = $_POST['ln'];
$uid = $_POST['id'];
$rad = $_POST['rd'];
$outs = 'python recommend.py ' . $uid . ' ' . $lat . ' ' . $lon . ' ' . $rad;
$output = shell_exec($outs);
echo $output;
?>
Whereas I tried to get the output using dummy variables, it is being shown.
<?php
$lat = $_POST['lt'];
$lon = $_POST['ln'];
$uid = $_POST['id'];
$rad = $_POST['rd'];
echo "11,28.720663,77.106192,1.18764869157,50.2058551405~12,28.705344,77.147270,2.854 76982119,2.42050298022~14,28.697590,77.143108,2.63211107261,13.1314821232~64,28. 683058,77.079048,2.10283926574,28.9526789043~66,28.670294,77.126684,2.8317092358 ,5.80484607006~67,28.677712,77.092713,1.95077211146,28.4871314757~68,28.665512,7 7.093081,2.76955528898,21.8407451837~71,28.674069,77.124547,2.53467055409,24.755 4907651~"
?>
My guess is that you need to provide the full path to the python script, i.e.:
python /full/path/to/recommend.py
As mentioned on my comments, in order to properly debug php, you'll need to enable error reporting at the top of your php scripts , i.e.:
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
//the rest of your code...
