[mapserver-users] Problem with wfs.php

Wed Oct 13 05:55:09 EDT 2010

Hi Robert,

The file_get_contents error you get doesn't come from your code but is return by the Carmen wfs server.
As Jukka said, your filter seems too long to be sent in a GET parameter. But when querying the wfs server in POST, you should send your query in XML and not use Key Value Pair encoding (FILTER=...).

In fact, the content of your POST query should look like this :

<?xml version="1.0" encoding="utf-8"?><GetFeature xmlns="http://www.opengis.net/wfs"  xmlns:ogc="http://www.opengis.net/ogc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Hi, 
I followed your instructions, I try use "curl-setopt-array" with "curl_multi_init". 

function curl_get_multi_content($list_layer) { 
$curl_init = array(); 

foreach($list_layer as $i => $layer) { 
unset($options); 
$options = array 
( 
CURLOPT_RETURNTRANSFER => true, 
CURLOPT_CONNECTTIMEOUT => 120, 
CURLOPT_TIMEOUT => 120, 
CURLOPT_POST => 1, 
CURLOPT_POSTFIELDS => $layer['data'].$layer['filter'], 
); 

$curl_init[$i] = curl_init($layer['url']); 
curl_setopt_array($curl_init[$i],$options); 
} 

$curl_multi = curl_multi_init(); 

foreach($list_layer as $i => $layer) { 
curl_multi_add_handle($curl_multi, $curl_init[$i]); 
} 
do { 
curl_multi_exec($curl_multi, $running); 
} while($running > 0); 

foreach($list_layer as $i => $layer) { 
echo curl_multi_getcontent($curl_init[$i]); 
$list_layer[$i] = $layer+Array('info'=>get_info_xml(curl_multi_getcontent($curl_init[$i]), $layer['name'])); 
curl_close($curl_init[$i]); 
} 
return $list_layer; 
} 

With my server, result is correct. I've a error with server Carmen :

Warning: Cannot modify header information - headers already sent by (output started at /applications/www/carmen/WFS/wfs.php:123) in /applications/www/carmen/WFS/wfs.php on line 91. 

It's the same message of the first error (number of ligne changed), but the function working properly on my server!!!! 

Thanks for your help.

Hi, 

Don't use file_get_contents but cURL rather: 
http://www.php.net/manual/fr/function.curl-setopt-array.php 

Regards, 

Y.
