How to send input from HTML Form and use it in php CURL function

Question

I'm new to web programming and I was looking to find the solutions on the internet but I get stuck, so anyone can help me I would appreciate his effort very much.

I have two files. The first file is an HTML form like this.

<html>
<title>index.html</title>
<body>

<form action="index.php" method="post">
Title <input type="text" name="title" /> <br>
Cat <input type="text" name="cat" /> <br>
Private <input type="text" name="private" /> <br>
Description <textarea name="description" rows="10" cols="40"></textarea>  <br>
Size <input type="text" name="size"  /> <br>
RON <input type="text" name="RON" /> <br>
Price <input type="text" name="price" /> <br>
Price NO <input type="text" name="price2"  /> <br>
Stare <input type="text" name="used" /> <br>
Nume <input type="text" name="name"  /> <br>
city <input type="text" name="city" /> <br>
Email <input type="text" name="email"  /> <br>
ON <input type="text" name="on" /> <br>
<input type="submit" name="submit" value="submit" /><br>
</form>



</body>
</html>

The second file is index.php and have this code.

<?php
 $title = $_POST['title'];
 $cat = $_POST['cat'];
 $private = $_POST['private'];
 $description = $_POST['description'];
 $size = $_POST['size'];
 $RON = $_POST['RON'];
 $price = $_POST['price'];
 $price2 = $_POST['price2'];
 $used = $_POST['used'];
 $name = $_POST['name'];
 $city = $_POST['city'];
 $email = $_POST['email'];
 $on = $_POST['on'];


//create array of data to be posted

$post_data = array(
'data[title]' => $title,
'data[category_id]' => $cat,
'data[private_business]' => $private,
'data[description]' =>  $description,
//'data[description]' => 'Description: Pantofi de lac, pantofi , pantofi Pantofi de lac, pantofi , pantofi Pantofi de lac, pantofi , pantofi ',

);


//traverse array and prepare data for posting (key1=value1)
foreach ( $post_data as $key => $value) {
    $post_items[] = $key . '=' . urlencode($value);
}

//create the final string to be posted using implode()
$post_string = implode ('&', $post_items);

//create cURL connection
$curl_connection =
  curl_init('http://olx.ro/i2/adauga-anunt/');

//set options

I'm trying to use the HTML form to send the values to curl $post_data (array) and CURL to do his job and post to the $url provided. I tested with echo $_POST('title') and the php page is receiving the input data but CURL don't execute it and I can't figure out why.

Think you should check this Q/A and also the accepted answer here. With setting the correct header curl_setopt($c, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data")); you can send array via http_build_query(). — skobaljic

Thanks a lot, but still not working. Since I added variable on the array value array 'data[title]' => $title'code' is not working, but in the first step was working and used in array like this "data[title]' = > 'the title'," without variable. I also tested to see if the php page receive the form values using echo $_POST('title'); — Andrew Chi

In this example you are using GET method and using CURLOPT_POSTFIELDS.

To use POST keep your existing code but add

 curl_setopt ($curl_connection, CURLOPT_POST, 1);

before the line

    //set data to be posted
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string);

If you want to use the GET remove:

//set data to be posted
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string);

update to

    enter code he//create cURL connection
$curl_connection =
  curl_init('http://olx.ro/i2/adauga-anunt?'.$post_string);
