php cURL doesnt print out anything - php

Question

I am trying to send a HTML form POST data with a cURL, but it seems the response is always empty. I first save all the POST data in an array, and use an implode function. When I echo out the implode string it does return the values, but after the cURL it's just empty.
This is the setup. I call this function after submitting the form
$this->OCIcURL($this->request->post);
public function OCIcURL($post) {
$data_oci = array();
$items_oci = array();
$counter = 0;
$data_oci['~caller'] = 'CTLG';
foreach ($post['item'] as $key => $value)
{
$counter++;
$data_oci['NEW_ITEM-DESCRIPTION[' . $counter . ']'] = $value;
$data_oci['NEW_ITEM-MATNR[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-QUANTITY[' . $counter . ']'] = $post['amount'][$counter];
$data_oci['NEW_ITEM-UNIT[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-PRICE[' . $counter . ']'] = $post['price'][$counter];
$data_oci['NEW_ITEM-CURRENCY[' . $counter . ']'] = $this->session->data['currency'];
$data_oci['NEW_ITEM-PRICEUNIT[' . $counter . ']'] = 1;
$data_oci['NEW_ITEM-LEADTIME[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-VENDOR[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-VENDORMAT[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-MANUFACTCODE[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-MANUFACTMAT[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-MATGROUP[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-SERVICE[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-CONTRACT[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-CONTRACT_ITEM[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-EXT_QUOTE_ID[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-EXT_QUOTE_ITEM[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-EXT_PRODUCT_ID[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-ATTACHMENT[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-ATTACHMENT_TITLE[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-ATTACHMENT_PURPOSE[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-EXT_SCHEMA_TYPE[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-EXT_CATEGORY_ID[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-CUST_FIELD1[' . $counter . ']'] = 21;
$data_oci['NEW_ITEM-PARENT_ID[' . $counter . ']'] = "";
$data_oci['NEW_ITEM-ITEM_TYPE[' . $counter . ']'] = "";
}
foreach ($data_oci as $key => $value)
{
$items_oci[] = $key . '=' . $value;
}
$string_oci = implode('&', $items_oci);
If I echo out the $string_oci I do get a result. After this I use the cURL to send the string to a link.
$url = "http://localhost/test.php";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $string_oci);
curl_setopt($ch, CURLOPT_RETURNTRANSFER , 1); // RETURN THE CONTENTS OF THE CALL
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$response = curl_exec($ch);
var_dump($response);
}
The var_dump is always empty, returning string(0) "". I also tried this on the live website, same result.
I used this piece of code to see any errors, but it seems it there arent any error at all, but the var_dump is always empty.
if (curl_exec($ch) === FALSE)
{
print_r(curl_getinfo($ch));
die("Curl error: " . curl_error($ch));
}
else
{
curl_close($ch);
}

Answer 1

$endpoint="http://localhost/test3.php";
$session = curl_init($endpoint);
curl_setopt($session, CURLOPT_POST, true);
curl_setopt($session, CURLOPT_HEADER, true);
curl_setopt($session, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($session, CURLOPT_POSTFIELDS, $string_oci);
curl_setopt($session, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($session);
var_dump($response);
curl_close($session);
You need a header in your curl request and your curl_init needs a url. Try the code i attach.
