Modify Header Error Warning: Cannot modify header information -

eddygalvin · June 13, 2010

hello i have written an php to send signups to a webpage on a different sever. But when textrunning, i got a warning error

Warning: Cannot modify header information - headers already sent by (output started at /home/gminds/public_html/SendSignupHttp.php:86) in /home/gminds/public_html/SendSignupHttp.php on line 59

Although the signup process was complete this warning would bounce vistors off my site. i have checked but have not found what was wrong with the script. i have attached the scripts below. Any help on resolving this issue will be highly appreciated. thanks.

this is the first script SendSignupHttp.php

{

/*Require the PostRequest function for posting the API request to the server */

require ("PostRequest.php");

$resellerusername = "rock";

$isReseller = $_POST['rbIsReseller'];

$username = $_POST['txtUserName'] ;

$password = $_POST['txtPassword'] ;

$companyname = $_POST['txtCompany'];

$firstname = $_POST['txtFirstName'];

$lastname = $_POST['txtLastName'];

$cellphone = $_POST['txtCellPhoneNumber'];

$email = $_POST['txtEmail'];

$address = "";

$city = $_POST['txtCity'];

$state = $_POST['txtState'];

$country = $_POST['txtCountry'];

$emailtosms = "0";

/* ==================================================

// submit these variables to the server

$data = array( 'ResellerUN' => $resellerusername ,

'CustomerUN' => $username ,

'EmailToSms' => $emailtosms,

'PASSWORD' => $password);

// send a request to the API url

list($header, $content) = PostRequest("http linenums:0'><?php function submitSignUpForm(){ if(isset($_POST['txtUserName'])) { /*Require the PostRequest function for posting the API request to the server */ require ("PostRequest.php"); $resellerusername = "rock"; $isReseller = $_POST['rbIsReseller']; $username = $_POST['txtUserName'] ; $password = $_POST['txtPassword'] ; $companyname = $_POST['txtCompany']; $firstname = $_POST['txtFirstName']; $lastname = $_POST['txtLastName']; $cellphone = $_POST['txtCellPhoneNumber']; $email = $_POST['txtEmail']; $address = ""; $city = $_POST['txtCity']; $state = $_POST['txtState']; $country = $_POST['txtCountry']; $emailtosms = "0"; /* ================================================== SUBMIT A REQUEST TO SIGN UP VIA THE HTTP API =====================================================*/ // submit these variables to the server $data = array( 'ResellerUN' => $resellerusername , 'CustomerUN' => $username , 'IsReseller' => $isReseller, 'FN' => $firstname, 'LN' => $lastname , 'EMAIL' => $email , 'COMPANY' => $companyname , 'ADDRESS' => $address , 'CITY' => $city , 'STATE' => $state , 'COUNTRY' => $country , 'CELL' => $cellphone , 'EmailToSms' => $emailtosms, 'PASSWORD' => $password); // send a request to the API url list($header, $content) = PostRequest("http://74.126.82.44/smsapi/CustomerSignUp.aspx?", $data); // display the result of the request //echo $content .

The problem is that you put submitSignUpForm(); within an HTML context. submitSignUpForm() contains a header() function, but the header() function can only work if you did not already send non-header data to the browser.
