I need a php page, when loaded, to send a POST request automatically without using a submit button or any user input. I don't need to do anything with the response.
I simply need to POST "8" to www.mydomain.com
$url = 'http://www.mydomain.com/';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 8);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
What am I doing wrong?
Try this:
curl_setopt($ch, CURLOPT_POSTFIELDS, array('data' => 8));
On your domain edit script to:
echo $_POST['data'];
Kind of a strange request .. you should consider using a key for the value of 8.
You can, however, get the POST body on http://www.mydomain.com/ by reading 'php://input'.
//on www.mydomain.com/index.php
echo file_get_contents('php://input'); //8
By the way you also have $curl instead of $ch on the third setopt.

I have this code to POST data to an url that is receiving the data with below, with content-type header set as text/html
file_get_contents("php://input");
This is the code That I used to POST to url and it is sending the data, but without values (i'm sending an array data with key values).
$url = "http://url im sending data to";
$object = array(
"key1" => "123",
"key2" => "345",
"key3" => "567"
);
$data = http_build_query($object, '', '&');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTREDIR, 3);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
However, it's sending the data, but without the values, since I get a response back from the url saying that values are empty.
Moreover, I checked the curl_errno($ch) and it doesn't return anything so there is no error within my code (I think?)
Can someone help me out?!
Thanks in advance!
OK I solved the problem and it was pretty simple.
Just swap the http_build_query with json_encode, and make sure to only set the curl_setopt as it is.
add the bottom code also.
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
I don't know why but for some reason, if I add other curl_setopt variables like
curl_setopt($ch, CURLOPT_POST, true);
it does not work.
I'm trying to post JSON by using CURL, and I created a table to store the data and the response I get from the url that Im sending the data to.
However, the response keeps saying that my "Post data is empty", and I can't figure out why.
I tested it with websites like https://reqbin.com/ with the data that is stored in my table and it works fine, since I get a "successful" response.
Can someone help me figure out why my data keeps being emptied?
Below is my code
$url = "url that im trying to post Json to.";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($json_object));
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$result = curl_exec($ch);
I've also tried using the http_build_query but it does not work.
Thanks in advance!
PHP recognizes application/x-www-form-urlencoded standard data type by default
// one
$post = $GLOBALS['HTTP_RAW_POST_DATA'];
// two
$post = file_get_contents("php://input");
I need to send POST data to the remote form. I have a simple script...
$data['field1'] = '1';
$data['field2'] = '2';
$data['field3'] = '3';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.example.com/my-form.php?authToken=poWQyj2q");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$output = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
echo $output;
... It would be work nice, but there is a problem with form URL - How you can see, there is some "authToken" value which changes each time a page is loaded. When it is incorrect, the form is sent, but not processed.
Any ideas how to solve it? Thanks.
Request the page containing the form
Extract the auth token from the DOM
(Presumably) store the cookie value
Make your request but also include the auth token and the cookie
I have 2 sites, one main, one external. On the main site, I am using Lucene to search through it. The problem is, I am trying to also search through the external site.
The Form action for the external site:
<form action="https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT" method="post" name="search_tribute" >
I've tried to use curl, but it only brings up the search form without actually doing the search (the field is empty as well).
<?php
$ch = curl_init("https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, tname='hello');
$output = curl_exec($ch);
echo $output;
curl_close($ch);
?>
Any tips?
I don't have access to the form action since it's on an external site. All i have is a form that links to it when I submit it.
<?php
$ch = curl_init("https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array("teamName" => "hello", "searchType" => "team"));
$output = curl_exec($ch);
echo $output;
curl_close($ch);
?>
Can you try this?
I'm pretty sure it's supposed to be teamName instead of tName
Most search engine use GET and not POST .. you can try
// asumption
$_POST['search'] = "hello";
// Return goole Search Result
echo curlGoogle($_POST['search']);
function curlGoogle($keyword) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.google.com/search?hl=en&q=' . urlencode($keyword) . '&btnG=Google+Search&meta=');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FILETIME, true);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
Or if you want post then
curl_setopt($ch, CURLOPT_POSTFIELDS, array("search"=>"hello"));
Your php code is not valid syntax, it does not compile.
So if this is really what you have, your problem is that your file generates a fatal error.
That being said, this question is hard to answer since we don't know the site you want to grab your search results from.
Try modifying your line like this:
curl_setopt($ch, CURLOPT_POSTFIELDS, "search=hello");
or alternatively
curl_setopt($ch, CURLOPT_POSTFIELDS, array("search" => "hello");
Maby it will work, however it may be that more post data is required or that the element name is not correct.
You have to look at the form or try making a request and look at it with chromes developer tools or firebug.
Also there are a number of ways for external sites to prevent what you are doing, altough evertything can be worked around somehow.
Assuming that is not the case, I hope i could help you.
Try just putting it into an array.
as that will be the variable the $_POST checks on the other side
and just checked your link, its teamName for the field
$fields = array("teamName"=>"julia");
Then..
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
So your complete code is...
<?php
$ch = curl_init("https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT");
$fields = array("teamName"=>"julia");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
$output = curl_exec($ch);
var_dump($output);
curl_close($ch);
?>
I am able to send the GET request and receive the response at following line.
$curl_resp = curl_exec($curl);
I used the following to parse the response, but it does not work, I have manually set some values to $curl_resp but still not sure how to access the value of each tag of the xml separately.
$xml = simplexml_load_string($curl_resp);
NOTE: I recevice the actual xml but cant parse it, (I need to get each tag's value separately in a variable)
Code:
<?php
$service_url = ' The Url goes here';
$curl = curl_init($service_url);
$curl_post_data = array(
"PASSWORD" => 'pass',
"USERNAME" => 'username'
);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
$curl_resp = curl_exec($curl);
curl_close($curl);
Your variable $curl_response is different than $curl_resp (what you're trying to parse)
You can access the value of each tag just like any other array.
if the CURLOPT_RETURNTRANSFER option is not set then your $curl_resp will just return true/false.
if it is set you may be returning false or a poorly formed xml string. If you post more code or the actual curl response text we may be able to provide more info.
EDIT:
upon reading the code looks like you are assigning the response text to $curl_response instead of $curl_resp
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, "your url");
curl_setopt($ch, CURLOPT_USERAGENT, 'Googlebot/2.1 (+http://www.google.com/bot.html)');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
