what is wrong with this code can you tell me?

 

<?php
if(isset($_POST['submit']))
{
$city_town_name = $_POST['$city_town_name'];
$placename = '$city_town_name'; // city where you want local weather
$lang = 'en';
$place=urlencode($placename);
$place = utf8_encode($place);
$url = 'http://www.google.com/ig/api?weather='.$place.',$&hl='.$lang.'';
$ch = curl_init();
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0);
$raw_data = curl_exec ($ch);
curl_close ($ch);

$xml = simplexml_load_string($raw_data);
$condition = $xml->weather->current_conditions->condition['data'];
$temp_c = $xml->weather->current_conditions->temp_c['data'];
$humidity = $xml->weather->current_conditions->humidity['data'];
$icon = $xml->weather->current_conditions->icon['data'];

echo ("<h1>Local weather for $placename</h1>");

for ($i = 0; $i < count($xml->weather->forecast_conditions); $i++){
$data = $xml->weather->forecast_conditions[$i];
$day_of_week = $data->day_of_week['data'];
$low = $data->low['data'];
$high = $data->high['data'];
$condition = $data->condition['data'];
$day_of_week = utf8_decode($day_of_week);
$img = 'http://img0.gmodules.com/' . $data->icon['data'];
echo ("$day_of_week<br/><img src=\"$img\"/>$low°|$high°<br/>$condition<br/><br/>");
}
}
?>

<form action='weather.php' method='POST'/>
<input name='city_town_name' type='text' value=''/>

$placename = $city_town_name; // city where you want local weather

 

variables aren't interpolated in single quote ('') strings, they need to be double quoted ("") for the variable to be replaced by it's value. It's not neccessary for it to be quoted at all in this case though as you are simply assigning one variable's value to another.

 

Although, as Pikachu2000 mentioned, you should really be doing this:

 

$placename = $_POST['$city_town_name']; // city where you want local weather

this is how it looks

 

<?php
if(isset($_POST['submit']))
{
$city_town_name = $_POST['city_town_name'];
$placename = '$city_town_name'; // city where you want local weather
$lang = 'en';
$place=urlencode($placename);
$place = utf8_encode($place);
$url = 'http://www.google.com/ig/api?weather='.$place.',$&hl='.$lang.'';
$ch = curl_init();
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0);
$raw_data = curl_exec ($ch);
curl_close ($ch);

$xml = simplexml_load_string($raw_data);
$condition = $xml->weather->current_conditions->condition['data'];
$temp_c = $xml->weather->current_conditions->temp_c['data'];
$humidity = $xml->weather->current_conditions->humidity['data'];
$icon = $xml->weather->current_conditions->icon['data'];

echo ("<h1>Local weather for $placename</h1>");

for ($i = 0; $i < count($xml->weather->forecast_conditions); $i++){
$data = $xml->weather->forecast_conditions[$i];
$day_of_week = $data->day_of_week['data'];
$low = $data->low['data'];
$high = $data->high['data'];
$condition = $data->condition['data'];
$day_of_week = utf8_decode($day_of_week);
$img = 'http://img0.gmodules.com/' . $data->icon['data'];
echo ("$day_of_week<br/><img src=\"$img\"/>$low°|$high°<br/>$condition<br/><br/>");
}
}
?>

<form action='weather.php' method='POST'/>
<input name='city_town_name' type='text' value=''/>
<input type='submit' name='submit' value='get weather'/>

$placename = $_POST['city_town_name']; // city where you want local weather
$lang = 'en';
$place=urlencode($placename);
$place = utf8_encode($place);
$url = 'http://www.google.com/ig/api?weather='.$place.',$&hl='.$lang.'';
$ch = curl_init();
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0);
$raw_data = curl_exec ($ch);
curl_close ($ch);

$xml = simplexml_load_string($raw_data);
$condition = $xml->weather->current_conditions->condition['data'];
$temp_c = $xml->weather->current_conditions->temp_c['data'];
$humidity = $xml->weather->current_conditions->humidity['data'];
$icon = $xml->weather->current_conditions->icon['data'];

echo ("<h1>Local weather for $placename</h1>");

for ($i = 0; $i < count($xml->weather->forecast_conditions); $i++){
$data = $xml->weather->forecast_conditions[$i];
$day_of_week = $data->day_of_week['data'];
$low = $data->low['data'];
$high = $data->high['data'];
$condition = $data->condition['data'];
$day_of_week = utf8_decode($day_of_week);
$img = 'http://img0.gmodules.com/' . $data->icon['data'];
echo ("$day_of_week<br/><img src=\"$img\"/>$low°|$high°<br/>$condition<br/><br/>");
}
}
?>

<form action='weather.php' method='POST'/>
