We have a contact.html form that uses reCaptcha v2, whose backend processing is in a php file.
I've taken enough steps to understand that when we send the verification to google's api, the response comes back empty. Below is code that gave me this proof.
$url = 'https://www.google.com/recaptcha/api/siteverify?secret='.$secret.'&response='.$_POST["g-recaptcha-response"].'&remoteip='.$_SERVER['REMOTE_ADDR'];
$verify = file_get_contents($url);
echo $url;
if (empty($verify)) echo 'Failed to fetch data';`
However, when I manually enter the url into a browser, I get a JSON response back that indicates success.
What, then, is the difference? Why would file_get_contents return empty if a simple get request from a Chrome browser give me trouble?
I have read that file_get_contents is synchronous, so I wouldn't expect this is just a noob error on waiting for the response.
Any help would be appreciated, this is my very first time working with PHP. It's not hard, but I may be missing something vital.
Sorry everyone, I can't understand why, but the problem was in the method used to access the site verify.
Using curl syntax, I finally got it working.
Change the configuration in php.ini file and don't need curl.
allow_url_fopen=0 to allow_url_fopen=1

I am having troubles with my PHP application which uses Drive SDK. I am trying to update a file, but all the time I receive 500 Internal Error message when I try to update file's contents.
I am looking for some way to debug the application. What would be most helpful for me is possibility to view how the entire request along with all headers look like. Is there any way to check it, or are there any other options for debugging?
Thank you a lot for your time.
I still didn't find any option for debugging- However, I found how I can view the requests done by the API client.
Open google-api-php-client/io/Google_REST.php file and find static public function execute(Google_HttpRequest $req) function.
There you will find this line:
$httpRequest = Google_Client::$io->makeRequest($req);
Right under it put the following code: var_dump($httpRequest);
During every request the client will do, you will get dump of it's request.
This question is still relevant but the accepted answer is very old. If you wish to view the HTTP requests and server responses in version three, the file you need to edit is /vendor/google/apiclient/src/Google/Http/REST.php. Locate the doExecute function and add print_r($request->getUri()); to the first line. Add print_r($response->getBody()->read(1024)); to the line just before the function returns to see the response body.
I have signed up to a synonym API.. see the details on this page
I am having trouble implementing this in my php code.
If I copy and paste the link into the web browser, I can see the results no problem.
Instead of typing the word in manually, I wish to have a variable in the link with the relevant word i.e. $variable_with_word_stored as shown below.
http://words.bighugelabs.com/api/2/xxxxxxxx/$variable_with_word_stored/php
//format could be php (I would unserialize)..or json..I could decode it?
Any ideas guys? Thanks.
It sounds like you mean you want the result from calling that webpage and store it in a variable. What you should be looking to do is sending a http get request to that page within the code.
Check out using curl with php, you can send a http request to your requested url, capture the result back and parse it through json_decode
http://php.net/manual/en/curl.examples-basic.php
try it like this, maybe that you dont need curl:
$key = "xxxxxxxx";
$word = "love";
echo file_get_contents("http://words.bighugelabs.com/api/2/$key/$word/php");
I am quite frustrated with a very weird issue. I am trying to do a very simple thing here. I would like to post a form to an endpoint. I tried using the following command:
curl -d "Contact=Aditya&address1=1510 E. 9th Street&address2=Apt. 111&city=Tucson&state=AZ&zip=85719&Phone1=5207849817&Phone2=1237849812&email=aditya15417#yahoo.com&key2=09 New Lead&key5=AmpushU&uhsgradyr=1950&uhighlevel=AA&ucourseint=BA Internet Mktg&uCampaignID=Herlambang&utextperm=YES&uleaddate=20110910&uleadtime=19:18 PST" http://dev.degreeamerica.com/candidate_test.php
And yes it succeeds just fine, however when I try it via the site it gives me an error. Can someone tell me what I did wrong? The parameter I have on the curl is just something I copy and paste from firebug POST request, so the parameter is all the same.
Is there something wrong with me doing the AJAX?
You can't receive the results of a cross-domain post like that. Your page is on adityaherlambang.com, but you're posting to degreeamerica.com, so you can't get the results
One solution is to use a server-side proxy on adityaherlambang.com, and post using libcurl to degreeamerica.com, while returning whatever kind of status you want to your own site's JavaScript.
I'am building simple Ajax application (via jquery). I have strange issue. I found where the problem is, but I don't know how to solve it.
This is simple server-side php code:
<?php
require('some.php');
$return['pageContent'] = 'test';
echo(json_encode($return));
?>
On the client side, the error "Invalid JSON" is thrown.
I have discovered that if I delete require function, everything work fine.
Just for information, the "some.php" is an empty php file. There is no error when I open direct php files.
So, conclusion: I cant use require or include function if I want to use ajax?
Use Firebug to see what you're actually getting back during the AJAX call. My guess is that there's a PHP error somewhere, so you're getting more than just JSON back from the call (Firebug will show you that). As for your conclusion: using include/require by itself has absolutely no effect on the AJAX call (assuming there are no errors).
Try changing:
<?php
require('some.php');
$return['pageContent'] = 'test';
echo(json_encode($return));
?>
To:
<?php
$return = array(
'pageContent' => 'test'
);
echo json_encode($return);
?>
The problem might have to do with $return not being declared as an array prior to use.
Edit: Alright, so that might not be the problem at all. But! What might be happening is you might be echoing out something in the response. For example, if you have an error echoing out prior to the JSON, you'd be unable to parse it on the client.
if the "some.php" is an empty php file, why do you require it at all?!
require function throws a fatal error if it could't require the file. try using include function instead and see what happens, if it works then you probably have a problem with require 'some.php';
A require call won't have any effect. You need to check your returned output in Firebug. If using Chrome there is a plugin called Simple REST Client. https://chrome.google.com/extensions/detail/fhjcajmcbmldlhcimfajhfbgofnpcjmb through which you can quickly query for stuff.
Also, it's always good to send back proper HTTP headers with your response showing the response type.
It's most likely the BOM as has been discussed above. I had the same problem multiple times and used Fiddler to check the file in hex and noticed an extra 3 bytes that didn't exist in a prior backup and in new files I created. Somehow my original files were getting modified by Textpad (both in Windows). Although when I created them in Notepad++ I was fine.
So make sure that you have your encoding and codepages set up properly when you create, edit, and save your files in addition to keeping that consistent across OSes if you're developing on windows let's say and publishing to a linux environment at your hosting provider.
I want post tweets into facebook using php curl , this is my snippet I used for posting tweet into FB - FB CURL SNIPPET
But i am not find any updated tweet in my facebook,
am not sure but i thing somthing goes wrong,
Can you tell me, snippet is correct one or not?
Thanks
This calls for debugging.
First port of call: It could be that the cookies are not saved: Check whether the script actually generates a my_cookies.txt file. If it doesn't, create an empty one and do a chmod 777 on it.
Second port of call: curl_error().
Replace every curl_exec() call in the snippet by this:
$success = curl_exec(....... your options .....);
if (!$success) echo "CURL Error: ".curl_error();
this might give you some pointers as to what goes wrong.
However, seeing as the script tries to imitate a browser instead of using an API, it could be that the structure of the submission form has changed on Facebooks's side, in which case you'll have to parse the output cURL gives you and see what goes wrong.
All in all, if there is any way to do this cleanly through an API - I don't know whether there is - it would be much preferable to this.
