Post or Submit Form Data with PHP CURL

Last Sunday, I was working with website form to collect data from third party website. If you have to just submit form its easy website does not restrict to use CURL in order to post data but my requirement was to post website from data and store that data in my database too. This is easy and simple and has a lot of ways to do.

Now I would like to show you PHP CURL way to post form data. You can use PHP Jquery and Ajax to make it more fancy. But I want to keep it simple.

Step 1 -

I am using one sales force form as example.

<form action="curl.php" method="POST">
<input type=hidden name="oid" value="70D400000009mU7">
<input type=hidden name="retURL" value="http://www.site.com/thankyou.html">
<label for="first_name">First Name</label><input  id="first_name" maxlength="40" name="first_name" size="20" type="text" /><br>
<label for="last_name">Last Name</label><input  id="last_name" maxlength="80" name="last_name" size="20" type="text" /><br>
<label for="street">Address</label><textarea name="street"></textarea><br>
<label for="city">City</label><input  id="city" maxlength="40" name="city" size="20" type="text" /><br>
<label for="zip">Zip</label><input  id="zip" maxlength="20" name="zip" size="20" type="text" /><br>
<label for="email">Email</label><input  id="email" maxlength="80" name="email" size="20" type="text" /><br>
<label for="phone">Phone</label><input  id="phone" maxlength="40" name="phone" size="20" type="text" /><br>
<input type="submit" name="submit">
</form>

Step 2  - 

This is standard PHP CURL script (curl.php) to post from you can use anywhere without any modification in from you can add more fields if you need.

<?php

*/

//Initialize the $query_string variable for later use
$query_string = "";
 
//If there are POST variables
if ($_POST) {
 
//Initialize the $kv array for later use
$kv = array();
 
//For each POST variable as $name_of_input_field => $value_of_input_field
foreach ($_POST as $key => $value) {
 
//Set array element for each POST variable (ie. first_name=lakhsidhu)
$kv[] = stripslashes($key)."=".stripslashes($value);
 
}
 
//Create a query string with join function separted by &
$query_string = join("&", $kv);
}
//Check to see if cURL is installed ...
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
 
//The original form action URL from Step 2 :)
$url = 'https://www.site.com/path.php';
 
//Open cURL 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($kv));
curl_setopt($ch, CURLOPT_POSTFIELDS, $query_string);
 
//Set some settings that make it all work :)
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
 
//Execute SalesForce web to lead PHP cURL
$result = curl_exec($ch);
 
//close cURL connection
curl_close($ch);
if($result=='ok')
{
echo '<script>alert("Posted -- ")</script>';
}
// Here you can write mysql query to insert data in table.
 
$insert_tbl_index_page= "insert into tbl_form_data(first_name,last_name,street,city,zip,phone,email)values('$first_name','$last_name','$street','$city','$zip','$phone','$email')";

?>
