I got problem with ampersand + curren in my POST string on curl processing - instead POST values I got sunny character - ยค.
My question is:
how to send
['currency' => 'somevalue', 'otherkey' => 'othervalue']
with POST via curl.
I tried to form my POST as
$post_val = "otherVal=1¤cy=USD";
or
$post_val = "otherVal=1¤cy=USD";
or
$post_val = urlencode("otherVal=1¤cy=USD");
and then
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_val);
What is strange - it gives the same effect when I pass currency as first in string - "currency=USD&otherVal=1".
Also I tried
$array = http_build_query(['currency' => 'somevalue', 'otherkey' => 'othervalue']);
curl_setopt($ch, CURLOPT_POSTFIELDS, $array);
Perhaps curl allways make http_build_query which also gives some additional signs which the source server can not interpret correctly?
Any ideas how to solve it?
cheers
Simple way out
$data = array('otheritem'=>'item', 'currency'=>'usd');
curl_setopt($ch, CURLOPT_POST,TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
this should work

Im a newbie im trying to get a script to trigger another script with Curl in PHP but it dosent seem to be sending the paramaters.
Is there a seperate function to append parameters?
<?php
$time = time();
$message = "hello world";
$urlmessage = urlencode( $message );
$ch = curl_init("http://mysite.php?message=$urlmessage&time=$time");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
?>
Could anyone point me in the right direction??
The accepted answer is good for POST, but what if OP wanted specifically to GET? Some REST APIs specify the http method and often it's no good POSTing when you should be GETting.
Here is a fragment of code that does GET with some params:
$endpoint = 'http://example.com/endpoint';
$params = array('foo' => 'bar');
$url = $endpoint . '?' . http_build_query($params);
curl_setopt($ch, CURLOPT_URL, $url);
This will cause your request to be made with GET to http://example.com/endpoint?foo=bar. This is the default http method, unless you set it to something else like POST with curl_setopt($ch, CURLOPT_POST, true) - so don't do that if you specifically need to GET.
If you need to use one of the other http methods (DELETE or PUT for example) then use curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method). This also works for GET and POST.
You need curl_setopt() along with the CURLOPT_POSTFIELDS param.
That'll POST the given params to the target page.
curl_setopt($ch, CURLOPT_POSTFIELDS, 'foo=1&bar=2&baz=3');
PS: also check http_build_query() which is handy when sending many variables.
you need set CURLOPT_POST as true and CURLOPT_POSTFIELDS => parameters
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $parameters);
a suggestion,set 'CURLOPT_RETURNTRANSFER', as true to return the transfer as a string of the return value of curl_exec($ch) instead of outputting it out directly
Here is A Simple Solution for this.
$mobile_number = $_POST['mobile_number'];
$sessionid = $_POST['session_id'];
CURLOPT_URL => 'https://xxyz.jkl.com/v2.0/search?varible_that_you_want_to_pass='.$mobile_number.'&requestId=1616581154955&locale=en-US&sessionId='.$sessionid,
I need to do the following using PHP curl:
curl "https://the.url.com/upload"
-F file="#path/to/the/file"
-F colours[]="red"
-F colours[]="yellow"
-F colours[]="blue"
The code I have tried:
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, [
'file' => curl_file_create($file),
'colours' = ['red','yellow','blue']
]);
$response = curl_exec($ch);
But I just get an error 'Array to string conversion in... (the colours line)'. If I remove the colours entirely then it works but I need to include them.
I have tried putting the post fields array in http_build_query() but then the server returns '415 Unsupported Media Type'. I'm guessing because it's missing a mime type (the file is a custom binary file).
I have also tried...
'colours[1]' = 'red'
'colours[2]' = 'yellow'
'colours[2]' = 'blue'
But the server returns an error saying colours must be an array. It's as though I need to create an associative array but with duplicate keys... which I know I can't do.
Can anyone help?
From the document of CURLOPT_POSTFIELDS.
This parameter can either be passed as a urlencoded string like 'para1=val1¶2=val2&...' or as an array with the field name as key and field data as value. If value is an array, the Content-Type header will be set to multipart/form-data.
The function http_build_query() will make the value becomes 'para1=val1¶2=val2&...'.
So, I use this as post fields value as array and it work.
$postFields['hidden-input[0]'] = 'hidden value (from cURL).';
In your case, it should be.
curl_setopt($ch, CURLOPT_POSTFIELDS, [
'file' => curl_file_create($file),
'colours[0]' => 'red',
'colours[1]' => 'yellow',
'colours[2]' => 'blue',
]);

The manual array (name[0]) copied from PHP document in Example #2 CURLFile::__construct() uploading multiple files example.
While the answer from #vee should have worked, this came down to validation on this particular server application. After consulting with the vender, I ended up having to do this:
$headers = ['Content-type: multipart/form-data'];
$postFields = [
// NEEDED TO INCLUDE THE MIME TYPE
'file' => curl_file_create($file, mime_content_type($file)),
'colours[]' => ['red', 'yellow', 'blue'],
];
// NEEDED TO REMOVE THE NUMBERS BETWEEN SQUARE BRACKETS
$postFieldString = preg_replace('/%5B[0-9]+%5D/simU', '', http_build_query($postFields));
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, $headers);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFieldString);
$response = curl_exec($ch);
I'm new to using cURL, but from what I have read, the following should post the variables to the page, then print the result. The result prints, but it doesn't seem like the POST variables went because no results are generated. FireBug doesn't show anything going either. Any ideas what I'm doing wrong?
Thanks for your help!
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://butlercountyclerk.org/bcc-11112005/ForeclosureSearch.aspx");
$data = array(
'Search:btnSearch' => 'Search',
'Search:ddlMonth' => '1',
'Search:ddlYear' => '2011'
);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
echo $output;
Based on the coding of the site, it appears that you're missing a number of variables. Take for example, the actual post request made to the search page:
__VIEWSTATE=dDwtMjk2Mjk5NzczO3Q8O2w8aTwxPjs+O2w8dDw7bDxpPDE+Oz47bDx0PDtsPGk8Mz47aTwxOT47PjtsPHQ8dDw7cDxsPGk8MD47aTwxPjtpPDI+O2k8Mz47aTw0PjtpPDU+Oz47bDxwPDIwMDY7MjAwNj47cDwyMDA3OzIwMDc+O3A8MjAwODsyMDA4PjtwPDIwMDk7MjAwOT47cDwyMDEwOzIwMTA+O3A8MjAxMTsyMDExPjs+Pjs+Ozs+O3Q8QDA8Ozs7Ozs7Ozs7Oz47Oz47Pj47Pj47Pj47PmVlaXw5JK161vti9TC+QMdeTNQI&Search:ddlMonth=1&Search:ddlYear=2011&Search:txtCompanyName=&Search:txtLastName=&Search:txtCaseNumber=&Search:btnSearch=Search
This is post-feeding though URLDecode by the way. What this means though, is that your array of 3 values is missing data. At the very least, I'd suspect that Search:btnSearch=Search is missing, and would suggest that you implement all fields into your POST request.
I am trying to post to a REST service using PHP cURL but I'm after running into a bit of difficulty (this being that I've never used cURL before!!).
I've put together this code:
<?php
error_reporting(E_ALL);
if ($result == "00")
{
$url = 'http://127.0.0.1/xxxxxx/AccountCreator.ashx'; /*I've tried it a combination of ways just to see which might work */
$curl_post_data = array(
'companyName' =>urlencode($companyName),
'mainContact' =>urlencode($mainContact),
'telephone1' =>urlencode($telephone1),
'email' => urlencode($email),
'contact2' => urlencode($contact2),
'telephone2' => urlencode($telephone2)
'email2' => urlencode($email2);
'package' => urlencode($package)
);
foreach($curl_post_data as $key=>$value) {$fields_string .=$key. '=' .$value.'&';
}
rtrim($fields_string, '&');
die("Test: ".$fields_string);
$ch = curl_init();
curl_setopt ($ch, CURLOPT, $url);
curl_setopt ($ch, CURLOPT_POST, count($curl_post_data));
curl_setopt ($ch, CURLOPT_POSTFIELDS, $fields_string);
$result = curl_exec($ch);
curl_close($ch);
Following this, my code sends an email and performs an IF statement. I know this works okay, I only started running into trouble when I tried to insert this cURL request.
I've tried this however it doesn't run. As I am integrating with payment partners, it just says:
Your transaction has been successful but there was a problem connecting back to the merchant's web site. Please contact the merchant and advise them that you received this error message. Thank you.
The exact error that was received was a HTTP 500 error.
Thanks.
foreach($curl_post_data as $key=>value) {$fields_string .=$key. '=' .value.'&';
value here is missing a dollar i guess
foreach($curl_post_data as $key => $value) {$fields_string .=$key. '=' .$value.'&';
have you tried die($fields_string); to see what are you actually sending to the merchant?
First of all: are you testing locally? Because that IP you're using is not a valid server address.
The constant to set the URL is called CURLOPT_URL:
curl_setopt ($ch, CURLOPT_URL, $url);
Also CURLOPT_POST must be true or false ( http://php.net/curl_setopt ), not a number (except for 1 maybe):
curl_setopt ($ch, CURLOPT_POST, true);
Here's some POST sample code: PHP + curl, HTTP POST sample code?
It would be best if you can provide your PHP version.
As of PHP 5, some handy functions are bundled in the core instead of separate PECL libraries.
// If you are working with normal HTTP requests, simply do this.
$curl_post_data = http_build_query($curl_post_data);
curl_setopt($ch, CURLOPT, $url);
// This is a boolean option, although passing non-zero integer
// will be type-casted to TRUE, count() is not the proper way.
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $curl_post_data);
// If you really want the next statement be meaningful, do this.
// Otherwise your HTTP response will be passed directly into
// the output buffer.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$result = curl_exec($ch);
Keep in mind that CURLOPT_POSTFIELDS in PHP supports file uploads, by adding a '#' character followed by a full file path as the value.
You don't want to call http_build_query() on such situations.
Sample code for file upload
$curl_post_data = array('file1' => '#/home/user/files_to_be_uploaded');
While you can optionally specify MIME type, see the documentation for more information.
As said, check your PHP version first. This feature only works in PHP 5, AFAIK there are companies still hosting PHP 4.x in their servers.
Have a look at http_build_query
How can I make a post request to a different php page within a php script? I have one front end computer as the html page server, but when the user clicks a button, I want a backend server to do the processing and then send the information back to the front end server to show the user. I was saying that I can have a php page on the back end computer and it will send the information back to the front end. So once again, how can I do a POST request to another php page, from a php page?
Possibly the easiest way to make PHP perform a POST request is to use cURL, either as an extension or simply shelling out to another process. Here's a post sample:
// where are we posting to?
$url = 'http://foo.com/script.php';
// what post fields?
$fields = array(
'field1' => $field1,
'field2' => $field2,
);
// build the urlencoded data
$postvars = http_build_query($fields);
// open connection
$ch = curl_init();
// set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);
// execute post
$result = curl_exec($ch);
// close connection
curl_close($ch);
Also check out Zend_Http set of classes in the Zend framework, which provides a pretty capable HTTP client written directly in PHP (no extensions required).
2014 EDIT - well, it's been a while since I wrote that. These days it's worth checking Guzzle which again can work with or without the curl extension.
Assuming your php install has the CURL extension, it is probably the easiest way (and most complete, if you wish).
Sample snippet:
//set POST variables
$url = 'http://domain.com/get-post.php';
$fields = array(
'lname'=>urlencode($last_name),
'fname'=>urlencode($first_name),
'email'=>urlencode($email)
);
//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string,'&');
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);

Also, don't forget to visit the appropriate page(s) in the PHP Manual
index.php
$url = 'http://[host]/test.php';
$json = json_encode(['name' => 'Jhonn', 'phone' => '128000000000']);
$options = ['http' => [
'method' => 'POST',
'header' => 'Content-type:application/json',
'content' => $json
]];
$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);
test.php
$raw = file_get_contents('php://input');
$data = json_decode($raw, true);
echo $data['name']; // Jhonn
For PHP processing, look into cURL. It will allow you to call pages on your back end and retrieve data from it. Basically you would do something like this:
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_URL,$fetch_url);
curl_setopt ($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt ($ch,CURLOPT_USERAGENT, $user_agent;
curl_setopt ($ch,CURLOPT_CONNECTTIMEOUT,60);
$response = curl_exec ( $ch );
curl_close($ch);
You can also look into the PHP HTTP Extension.
Like the rest of the users say it is easiest to do this with CURL.
If curl isn't available for you then maybe
http://netevil.org/blog/2006/nov/http-post-from-php-without-curl
If that isn't possible you could write sockets yourself
http://petewarden.typepad.com/searchbrowser/2008/06/how-to-post-an.html
For those using cURL, note that CURLOPT_POST option is taken as a boolean value, so there's actually no need to set it to the number of fields you are POSTing.
Setting CURLOPT_POST to TRUE (i.e. any integer except zero) will just tell cURL to encode the data as application/x-www-form-urlencoded, although I bet this is not strictly necessary when you're passing a urlencoded string as CURLOPT_POSTFIELDS, since cURL should already tell the encoding by the type of the value (string vs array) which this latter option is set to.
Also note that, since PHP 5, you can use the http_build_query function to make PHP urlencode the fields array for you, like this:
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($fields));
Solution is in target="_blank" like this:
http://www.ozzu.com/website-design-forum/multiple-form-submit-actions-t25024.html
edit form like this:
<form method="post" action="../booking/step1.php" onsubmit="doubleSubmit(this)">
And use this script:
<script type="text/javascript">
<!--
function doubleSubmit(f)
{
// submit to action in form
f.submit();
// set second action and submit
f.target="_blank";
f.action="../booking/vytvor.php";
f.submit();
return false;
}
//-->
</script>
Although not ideal, if the cURL option doesn't do it for you, may be try using shell_exec();
CURL method is very popular so yes it is good to use it. You could also explain more those codes with some extra comments because starters could understand them.
