reCaptcha breaks other validation? - php

I'm about to make a contact form with reCaptcha but when I apply the reCaptcha and make validation on that, my other validation on the forms won't work and I just can't seem to find out why? I have tried other ways to make the recaptcha validate but nothing works?
OLD CODE START:
if(isset($_POST['submit'])){

$data = json_decode($response);
if(isset($data->success) AND $data->success==true) {
header('Location:contact.php?CaptchaPass=True');

Problem
Your header inside if(isset($_POST['submit'])){ ... } is causing this error. header() is used to send a raw HTTP header to the browser. Whenever browser requests a page to the server, before server responds, it first sends the headers i.e what browser can expect next and browser can render itself accordingly, and then server sends the actual page.
if(isset($_POST['submit'])){
$url = 'https://www.google.com/recaptcha/api/siteverify';
$privatekey = "MY SECRET CODE GOES HERE";
$response = file_get_contents($url."?secret=".$privatekey."&response=".$_POST['g-recaptcha-response']."&remoteip=".$_SERVER['REMOTE_ADDR']);
$data = json_decode($response);
if(isset($data->success) AND $data->success==true) {
header('Location:contact.php?CaptchaPass=True'); // this is causing the error
}else{
header('Location:contact.php?CaptchaFail=True'); // this might cause the same problem in near future
}
}
Solution
Instead of validating recaptcha using superglobal $_GET, you can use a simple boolean variable to validate it.
$valid_recaptcha = false;
if(isset($_POST['submit'])){
$url = 'https://www.google.com/recaptcha/api/siteverify';
$privatekey = "MY SECRET CODE GOES HERE";
$response = file_get_contents($url."?secret=".$privatekey."&response=".$_POST['g-recaptcha-response']."&remoteip=".$_SERVER['REMOTE_ADDR']);
$data = json_decode($response);
if(isset($data->success) AND $data->success==true) {
$valid_recaptcha = true;
}
if($valid_recaptcha){
// you should do all your input validation and form processing here
}else{
// user has entered wrong recaptcha
}
}
And then you can render your page accordingly.
Edited:
Instead of this:
<?php if(isset($_GET['CaptchaPass'])){ ?>
<div class="detail" style="margin-left: 200px;" align="center">Din besked er nu sendt</div><br />
<?php } ?>
<?php if(isset($_GET['CaptchaFail'])){ ?>
<div class="detail" style="margin-left: 200px;" align="center">reCaptcha fejlede, prøv venligst igen</div><br />
<?php } ?>
you can do something like this to display the message:
<?php
if(isset($_POST['submit'])){
if($valid_recaptcha){
?>
<div class="detail" style="margin-left: 200px;" align="center">Din besked ernu sendt</div><br />
<?php
}else{
?>
<div class="detail" style="margin-left: 200px;" align="center">reCaptcha fejlede, prøv venligst igen</div><br />
<?php
}
}
?>
Re-edited:
I've typed and tested the entire code on my local machine, and it's working just as you had expected. I didn't touch validation.js because I think you can do browser side validation later on your own. Replace the $private_key with your secret private key, add a valid email address to $email_to and run the code on your system.
<?php
/*
* I don't know Danish language, but somehow I managed to understand your input field names.
* Thanks to google translate. :)
*/
function validate_email_address($email = false) {
return (preg_match('/^[^#\s]+#([-a-z0-9]+\.)+[a-z]{2,}$/i', $email))? true : false;
}

return (str_ireplace(array("\r", "\n", "%0a", "%0d", "Content-Type:", "bcc:","to:","cc:"), '', $field));
}
// Set email variables
$email_to = 'MY MAIL GOES HERE';
$email_subject = 'Formular: Kontakt os';
// Set required fields
$required_fields = array('navn', 'postnr', 'by', 'email', 'telefon', 'besked');
// set error messages
$error_messages = array(
'navn' => 'Skriv venligst dit navn',
'postnr' => 'Skriv venligst et gyldigt post nr',
'by' => 'Skriv venligst et gyldigt bynavn',
'email' => 'Skriv venligst en gyldig e-mail adresse',
'telefon' => 'Skriv venligst et gyldigt telefon nr',
'besked' => 'Skriv venligst en besked'
);
// Set form status
$form_complete = FALSE;

$validation = array();
// boolean variable to validate recaptcha
$valid_recaptcha = false;
if(isset($_POST['submit'])){

You should try reading the logs, which can be in different places depending on your OS and the server you're using (apache, nginx...).
You could also use xdebug
Internal Server Error messages indicate that something, in general, is wrong in programming.
While developing you have to enable to error log in PHP.ini file.
Then you can easily find out the errorenter link description here

Having issues with hiding and showing divs on an onchange

I am having issues firing off an on-change in the department drop-down field not sure if i wrote it correctly. The error is Uncaught TypeError: Cannot read property 'style' of null. I am trying to select a department like claims then it will fire off an onchange to show another drop-down called workrequested. I have not filled all the departments yet but that should not mater if i want to test it on couple departments first. I think it has to do with dvPassport1.style.display
<script>
function ShowHideDiv1() {
var Department = document.getElementById("Department");
var divPassport1 = document.getElementById("divPassport1");
divPassport1.style.display = Department.value == "Claims" || Department.value == "Flat 1"|| Department.value == "Flat 2"|| Department.value == "Hanging Bulk" || Department.value == "Hanging Store North" || Department.value == "Hanging Store South" || Department.value == "Inventory Integrity" || Department.value == "Rack Shoes" || Department.value == "Fine Jewelry"? "block" : "none";
}
function ShowHideDiv2() {
var Department = document.getElementById("Department");
var divPassport2 = document.getElementById("divPassport2");
divPassport2.style.display = Department.value == "JackPotLane" ? "block" : "none";
}

As far as I can see you want to get divPassport1 (divPassport1) and divPassport2 and not dvPassport1 and dvPassport2.
Change var dvPassport1 = document.getElementById("dvPassport1"); to var dvPassport1 = document.getElementById("divPassport1"); and second one respectively or correct the ids.
EDIT
I guess you are accessing elements too early and you DOM is not loaded yet. Move your js code to the end of page before closing body and wrap it following way to wait for window onload event:
<script>
(function() {
// your javascript code here
// the DOM will be available here
})();
</script>

export a csv file from the mysql database

The following code is to import a csv file into database.
<?php
include("includes/config.php");

$handle = fopen($file,"r"); // Open the file and read
while ($strBookData = fgetcsv($handle, 10000, ",")) { // To get Array from CSV
$strDatas[] = $strBookData;

Now i want to export it from the database. Please help me.
you can download adminer.php from this "http://www.adminer.org/" and that will do that job for you. It has all the option to download database in different formats like XML, CSV and text.

WP Comments Not Posting Correctly

I have been developing a custom wordpress theme from scratch and have run into a small problem with my comments.php file.
https://gist.github.com/phillipdews/dcebfec2016a93bd0169
I think the problem stems from line 44 of that file as when I try and leave a comment on my blog post whether logged in or not the comment processes by going to:
www.mydomain.com/postlink/wp-comments-post.php
When naturally it needs to go to:
www.mydomain.com/wp-comments-post.php
UPDATE
This is what i have decided to do! I started again from scratch and have coded out my comments.php file like this:
<div id="comments">
<?php if ( post_password_required() ) : ?>
<p>This post is password protected. Enter the password to view and comments</p>
</div>
<?php
return;
endif;
?>
<?php if ( have_comments() ) : ?>
<ol>
<?php wp_list_comments ( array( 'callback' => 'BRUM_Theme_comment') ); ?>
</ol>
<?php
elseif ( ! comments_open() && ! is_page() && post_type_supports( get_post_type(), 'comments' ) ) :
?>
<p>Comments are closed</p>
<?php endif; ?>
<?php comment_form(); ?>
</div>
I then added this snippet of code to my functions.php file! This has so far made my comments appear and people are also able to leave comments on my blog post! but as yet the 'Reply to' button is not rendering.
<?php
function BRUM_Theme_comment( $comment, $args, $depth ){
$GLOBALS['comment'] = $comment;
?>
<?php if ( $comment->comment_approved == '1'): ?>
<li>
<article id="comment-<?php comment_ID() ?>">
<?php echo get_avatar( $comment ); ?>
<h4>
<?php comment_author_link() ?>
</h4>
<time><a href="#comment-<?php comment_ID() ?>" pubdate><?php comment_date() ?> at <?php comment_time() ?></a></time>
<?php comment_text() ?>
</article>
<?php endif;
}
That's it so far! once I got the Reply button working I will ammend the code!
Try this:
<div id="respond">
<?php
if (!empty($_SERVER['SCRIPT_FILENAME']) && 'comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
die ('Please do not load this page directly. Thanks!');
if ( post_password_required() ) { ?>
This post is password protected. Enter the password to view comments.
<?php
return;
}
?>
<?php if ( have_comments() ) : ?>
<h2 id="comments"><?php comments_number('No comments', 'One comment', '% Comments' );?></h2>
<div class="navigation">
<div class="next-posts"><?php previous_comments_link() ?></div>
<div class="prev-posts"><?php next_comments_link() ?></div>
</div>
<ol class="commentlist">
<?php wp_list_comments(); ?>
</ol>
<div class="navigation">
<div class="next-posts"><?php previous_comments_link() ?></div>
<div class="prev-posts"><?php next_comments_link() ?></div>
</div>
<?php else : // this is displayed if there are no comments so far ?>
<?php if ( comments_open() ) : ?>
<!-- If comments are open, but there are no comments. -->
<?php else : // comments are closed ?>
<p>Comments are closed.</p>
<?php endif; ?>
<?php endif; ?>
<?php if ( comments_open() ) : ?>
<h2><?php comment_form_title( 'Leave an reply', 'Leave a reply in %s' ); ?></h2>
<div class="cancel-comment-reply">
<?php cancel_comment_reply_link(); ?>
</div>
<?php if ( get_option('comment_registration') && !is_user_logged_in() ) : ?>
<p>You must be logged in to post a comment.</p>
<?php else : ?>
<br class="c" />
<form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" id="commentform">
<?php if ( is_user_logged_in() ) : ?>
<p>Logged as <?php echo $user_identity; ?>. Log out »</p>
<?php else : ?>
<div>
<input type="text" value="Name" onblur="if (this.value == '') {this.value = 'Name';}" onfocus="if (this.value == 'Name') {this.value = '';}" name="author" id="author" size="22" tabindex="1" <?php if ($req) echo "aria-required='true'"; ?> />
</div>
<div>
<input type="text" value="Email" onblur="if (this.value == '') {this.value = 'Email';}" onfocus="if (this.value == 'Email') {this.value = '';}" name="email" id="email" size="22" tabindex="2" <?php if ($req) echo "aria-required='true'"; ?> />
</div>
<div>
<input type="text" value="Website" onblur="if (this.value == '') {this.value = 'Website';}" onfocus="if (this.value == 'Website') {this.value = '';}" name="url" id="url" size="22" tabindex="3" />
</div>
<?php endif; ?>
<br />
<div>
<textarea name="comment" id="comment" cols="58" rows="10" tabindex="4"></textarea>
</div>
<br class="c" />
<div>
<input name="submit" type="submit" id="submit" tabindex="5" value="Send" />
<?php comment_id_fields(); ?>
</div>
<?php do_action('comment_form', $post->ID); ?>
</form>
<?php endif; // If registration required and not logged in ?>
</div>
<?php endif; ?>
This may solve your issue in any Wordpress version since 3.1.
Do not forget to put this code in your template folder (comments.php)
That done the Job Lucas buddy! I had to tweak the code a little and remove the class from the OL and tweak my css as it was making the avatars 100% big and blury! So this is all I done to my css code in order to make the comments styled better:
#respond {float: left;}
#respond img {width: auto; height: auto; float: left; margin-right: 4px; border: 1px solid #aab59a; padding: 1px; border-radius: 10px;}
#respond ol li { background: #f1f1f1; margin:10px 0;padding:8px;border:2px solid #ccc;font-style:normal;list-style: none; border-radius: 10px;}
Also this is a nice feature that people can to their functions.php file as it makes the reply to link into reply to commentors name:
/*
* Change the comment reply link to use 'Reply to <Author First Name>'
*/
function add_comment_author_to_reply_link($link, $args, $comment){
$comment = get_comment( $comment );
// If no comment author is blank, use 'Anonymous'
if ( empty($comment->comment_author) ) {
if (!empty($comment->user_id)){
$user=get_userdata($comment->user_id);
$author=$user->user_login;
} else {
$author = __('Anonymous');
}
} else {
$author = $comment->comment_author;
}
// If the user provided more than a first name, use only first name
if(strpos($author, ' ')){
$author = substr($author, 0, strpos($author, ' '));
}
// Replace Reply Link with "Reply to <Author First Name>"
$reply_link_text = $args['reply_text'];
$link = str_replace($reply_link_text, 'Reply to ' . $author, $link);
return $link;
}
add_filter('comment_reply_link', 'add_comment_author_to_reply_link', 10, 3);
Hope others find it useful and thanks again it's working brilliantly!

Security Flaw in php form

Apparently my php email form is full of security vulnerabilities, what can I do to fix them?
And what i mean by security flaws, that is hackers/bots being able to inject additional headers(eg bcc) into my form and send spam in my name
Any suggestions?

use another contact template!
contact templates are a very vulnerable point in web sites, this one is really insecure (I guess / hope it's quite old).
A few points for the curious (only a first glance, there may be more issues)
the $name parameter is not escaped, malicious user can enter for example bcc addresses, which would be added to the header section, here
the regex for the $email parameter allows %, thus it is possible to enter url_encoded signs like < >
$comments is not secured, too..
Why exactly do you have the need to let users send email with aribtrary name and email address? Are you trying to be an open proxy?
P.S. Lines like this won't do what you probably intended, because they don't handle the case of no parameter or an array being passed.
trim($_POST['contactName']) === ''
