xpath("/xml_api_reply/weather/forecast_information"); $current = $xml->xpath("/xml_api_reply/weather/current_conditions"); $forecast_list = $xml->xpath("/xml_api_reply/weather/forecast_conditions"); ?>

city['data']; ?>

Today's weather

weather temp_f['data'] ?>° F, condition['data'] ?>

Forecast

weather

day_of_week['data']; ?>

low['data'] ?>° F - high['data'] ?>° F, condition['data'] ?>

You should stop using the short <? and <?= tags, and use the full <?php tag syntax.

$php_mysql$ · October 3, 2010

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=''/>
<input type='submit' name='submit' value='get weather'/>
</form>

i get

Notice: Undefined index: $city_town_name in C:\wamp\www\fiunc\weather.php on line 4

$city_town_name = $_POST['city_town_name']; //was $_POST['$city_town_name']

Pikachu2000 · October 3, 2010

Does these lines really make sense to you? Hint: they shouldn't . . .

$city_town_name = $_POST['$city_town_name'];

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

$php_mysql$ · October 3, 2010

lol happened for copy paste thanks :-) ok another issue now when i submit no results show?

$php_mysql$ · October 3, 2010

actually they do not make any im just for time being keeping it like that

Andy-H · October 3, 2010

$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

$php_mysql$ · October 3, 2010

those are fixed :-) but now is displaying after submiting i get blank page tho when i print the $city_town_name i get the result from what i submited using form. but rest nothing is displaying

Andy-H · October 3, 2010

Show the code as it currently stands.

$php_mysql$ · October 3, 2010

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'/>
</form>

after submit the weather data does not display

Andy-H · October 3, 2010

You didn't make the change I told you too...

<?php
if(isset($_POST['submit']))
{
$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'/>
<input name='city_town_name' type='text' value=''/>
