cURL validation on php form

[jsgsg]

I am trying to implement a validation process within the php wrapper for the new form.

The automatically gets submitted and completely ignores the validation process. Is there any reason why?

 

<?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=Arsham)
$kv[] = stripslashes($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.salesforce.com/servlet/servlet.WebToLead?encoding=UTF-8';
 
//Open cURL connection
$ch = curl_init();


if(isset($_POST['submit'])){

    if($_POST['first_name'] == ""){
        $error="Please enter a topic<br>";
    }

    if($_POST['last_name'] == ""){
        $error="Please enter a topic<br>";
    }

    if($_POST['phone'] == ""){
        $error="Please enter a topic<br>"; 
    }

    if($_POST['email'] == ""){
        $error="Please enter a topic<br>";
    }

    if($_POST['company'] == ""){
        $error="Please enter a topic<br>";
    }

    if(isset($error)){
        echo $error;
    }else{
        // Both fields have content in

    }
}
 
//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);

?>

Interesting question Where are the values that you wanna be submited? Could you show us the output of $query_string?

isset($_POST['submit']) is your main condition to trigger the validation block.... I'm guessing there is nothing called 'submit' being sent over...

 

Try changing isset($_POST['submit']) to !empty($_POST) and try again. If it works, you html is missing the 'submit' element.

You are calling your cURL stuff regardless of the result of your validation. You need to move the curl stuff into the else block of your if (isset($error)) branch

 

if (isset($_POST['submit'])){
    //your validations
    if (isset($error)){
       //display error
    }
    else {
       //your cURL stuff
    }
}
