problem with curl script

[rhock_95]

I am trying to use a curl script to retrieve a map based on form input

 

my form passes the data to the script and retrieves the map page but no map...however the URL is valid...i.e., if I take the same URL string following the "?" and paste it into the originating page the map displays

 

in the example below... after submitting the form (No Map displays) but if I copy the "coordinate string" and paste it over the coordinate string in the second example the map displays

 

[example]

 

mysite.com/curl_script.php?coordinate string  No map Displays

 

mapsite.com?/search.php?coordinate string    Map displays

 

here is the code I'm using:

    $ch = curl_init();
    
    curl_setopt($ch, CURLOPT_URL, "http://www.mapsite.com/search.php?");
   
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    
    $result = curl_exec($ch);

    curl_close($ch);

    echo "$result";

Try seeing if there is an error with cURL:

 

 

    $ch = curl_init();
    
    curl_setopt($ch, CURLOPT_URL, "http://www.mapsite.com/search.php?");
   
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    
    $result = curl_exec($ch);
    echo curl_error($ch);
    curl_close($ch);

    echo "$result";

 

Edit: It could be that you need to set other headers/curl options to make this work. If the site you are connecting to shows different information based on user agent for example, then you'll need to pass that along.

not getting any errors...is there a special function to echo cURL errors?

other than user agent what else should I look for in the http header logs ?

It rather depends on the website. I had one cURL request which failed due to a problem with the SSL certificate; for other sites you may need to specify a cookie etc.

[rhock_95]

you may need to specify a cookie etc.

 

can you show me how this is done?
