PHP send form to email - display content on next page - php

I'm having some issues with getting the form content sent to email and saved to a session and then displayed on next page.
I have form on contact.shtml which action takes it to mail.php and when content are sent goes to thank_you.shtml.
I need the content shown on the thank_you -page.
All my pages are *.shtml - are this an disadvantage for this?
Codesnippets:
mail.php
$name = $_POST['name'];
$_SESSION['name'] = $name;
$email = $_POST['email'];
$_SESSION['email'] = $email;
$phone = $_POST['phone'];
$_SESSION['phone'] = $phone;
thank_you:
<?php
echo "Navn:" . "$_SESSION['name']";
echo "Email:" . "$_SESSION['email']";
echo "Telefon:" . "$_SESSION['phone']";
?>
I have the obvious on page thank_you and mail.php.
<?php
session_start();
?>
Beside these few lines i have several more with text input and also image files for which i want to show the filename and extensions and also a small preview.
Am i missing something or on the complete wrong track?

You could bypass using a session. While I like separation of concerns the following outline 'all-in-one' solution would satisfy your problem:
<?php
$email = null;
$sent = false;
$error = null;
if($_SERVER['REQUEST_METHOD'] == 'POST') {
$email = isset($_POST['email']) ? $_POST['email'] : null;
if($email && filter_var($email, FILTER_VALIDATE_EMAIL)) {
// supplied email looks good, send email here.
$sent = true;
} else {
$error = 'Please enter a valid email address.';
}
}
?>
html goes here..
<?php if($sent) {
echo 'Thankyou. The email you supplied is: ' . htmlspecialchars($email);
?>
<?php } else { ?>
<?php echo $error ? '<p>' . $error . '</p>' : ''; ?>
<form method="POST">
Email:
<input type="text" name="email" value="<?php echo htmlspecialchars($email) ?>">
<input type="submit">
</form>
<?php } ?>
If a valid email is posted, you can then trigger your mail out.
Do you really need to display the gathered user data?

<?php
echo "Navn:" . htmlentities($_SESSION['name']);
echo "Email:" . htmlentities($_SESSION['email']);
echo "Telefon:" . htmlentities($_SESSION['phone']);
?>
You have to remove the quotes around the variables. Use htmlentities to convert all applicable characters to HTML entities

PHP Email Sanitization Filter

I'm trying to figure out why my sanitize filter don't work. When entering an email with incorrect characters, it displays the email with incorrect characters. I would have thought it will strip out incorrect characters and only display the correct email address. Below is my code. What am I doing wrong?
<?php
if(filter_has_var(INPUT_POST, 'data')){
$email = $_POST['data'];
//Now remove illegal characters
$email = filter_var($email, FILTER_SANITIZE_EMAIL);
echo $email;
}
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="text" name="data">
<button type="submit">Submit</button>
</form>
To me it seems to be working. I would however not want to store a different email than the exact input. If the incoming email adress is incorrect I would return an error message asking the user for a real email adress:
if(filter_has_var(INPUT_POST, 'data')){
$email = trim($_POST['data']);
$sanitized = filter_var($email, FILTER_SANITIZE_EMAIL);
if($email === $sanitized && filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo "This is a valid email: " . $email;
} else {
echo "This is an invalid email: " . $email;
}
}
I don't know if this is exactly what's you're looking for but just give it a try.
<?php
function filter_mail($string) {
return preg_replace('/[^A-Za-z0-9.#\-]/', '', $string); // We remove special chars and accept only Alphs&Nums&.&#
}
$mail="jp)(*&#gmail)**&.com";
echo filter_mail($mail); //This will output the desired email
echo "<br>";
echo $mail; //This is how it was !
?>
It seems like only certain types of characters can get sanitized. For instance here are examples of wrong emails that will get sanitized:
(comment)localpart#example.com - After sanitization: commentlocalpart#example.com
"much.more unusual"#example.com - After sanitization: much.moreunusual#example.com
But these for instance will not get sanitized:
sarah{[#gmail}{[.com - After sanitization: sarah{[#gmail}{[.com
jp*&#gmail**&.com - After sanitization: jp*&#gmail**&.com
this may help, after sanitizing we need to check if it is a valid mail
<?php
if(filter_has_var(INPUT_POST, 'data')){
$regex = '/^[_a-z0-9-]+(\.[_a-z0-9-]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/';
$email = $_POST['data'];
$email = filter_var($email, FILTER_SANITIZE_EMAIL);
if (preg_match($regex, $email)) {
echo $email;
} else {
echo "invalid email";
}
}
?>

Validating simple RSVP form through PHP

I am trying to validate my RSVP form using only PHP. The user should receive an error message when the form is incomplete. I am trying to avoid the use of jQuery.
I am using this tutorial:
http://premium.wpmudev.org/blog/how-to-build-your-own-wordpress-contact-form-and-why/
The form is functioning fine but I haven't been able to get the error messages to display at all. I am using Wordpress and I want the form to appear at the footer of every page; not sure if this complicates matters. Here is my code:
<?php
$response = "";
//function to generate response
function my_contact_form_generate_response($type, $message) {
global $response;
if ($type == "success") {
$response = "<div class='success'>{$message}</div>";
} else {
$response = "<div class='error'>{$message}</div>";
}
}
//response messages
$missing_content = "Please supply all information.";
$email_invalid = "Email Address Invalid.";
$message_unsent = "Message was not sent. Try Again.";
$message_sent = "Thanks! Your message has been sent.";
//variables defined for messages
$email = $_POST["rsvp_email"];
$name = $_POST["rsvp_name"];
$attend = $_POST["rsvp_attend"];
$number = $_POST["rsvp_number"];
//variables defined for message to admin
$to = get_option('admin_email'); //sending to wordpress admin email
$subject = "Just Kidding You Foo";
$headers = "From: $email\n";
$message = "$name $attend.\n RSVPs $number of people";
//conditional statements used for form validation
//validate email
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
my_contact_form_generate_response("error", $email_invalid);
} else { //email is valid
//validate presence of name and message
if(empty($name) || empty($attend) || empty($number)) {
my_contact_form_generate_response("error", $missing_content);
} else { //ready to go!
$sent = wp_mail($to,$subject,$message,$headers);
if($sent) {
my_contact_form_generate_response("success", $message_sent); //message sent!
} else {
my_contact_form_generate_response("error", $message_unsent); //message wasn't sent
}
}
}
?>
<div id="page-rsvp">
<h1>RSVP</h1>
<div id="respond">
<?php echo $response; ?>
<form action="<?php the_permalink(); ?>" method="post">
<!--Name here-->
<div class="rsvp-full"><label for="rsvp_name"><input type="text" name="rsvp_name" value="Your name"></label></div>

</form>
</div>
</div>
TIA!!!
I'm not that familiar with WP, but if I understand correctly, I believe you're trying to ensure all the fields are filled out.
Check your brackets! You need to be sure your curly brackets are opening and closing where you want them to. Otherwise the output of the page won't display. I write in all my braces because I'm not smart enough to be sure I know where they start and stop. I've taken the liberty of editing them into your question. I believe there was one missing at the end.
Once I fixed the brackets and removed functions my computer didn't have, it worked fine.
Tip 0: Try turning error reporting on for this script - error_reporting(E_ALL); at the top of this script. I always do for development.
Tip 1: use the placeholder attribute instead of value for things like "your name".
Tip 2: make sure the $_POST vars are set. I would do this by checking if they're set and then setting them to '' if they aren't; something like this:
//variables defined for messages
// you could do it like this:
if (isset($_POST["rsvp_email"])) {
$email = $_POST["rsvp_email"];
} else {
$email = '';
}
// or like this:
$name = '';
if (isset($_POST["rsvp_name"])) {
$name = $_POST["rsvp_name"];
}
// or even using a ternary operator:
$attend = isset($_POST["rsvp_attend"]) ? $_POST["rsvp_attend"] : '';
//but this will trigger a "Notice" error if the post var isn't set.
$number = $_POST["rsvp_number"];

after clicking submit on a contact form, how do i stay on the same page in wordpress?

So I created a custom contact form in WordPress, using PHP. The form sends, and I am receiving emails. The problem I'm having is that once you hit submit, it goes to a post page, and doesn't stay on the original page.
I've tried using a session and header location (didn't work)
I also tried putting this in my action"<?php echo $_SERVER['PHP_SELF']; ?>", doesn't work either. (mail just doesn't send it and sends me to 404 page.
So I'm a little stuck, as to fix this problem. Normally I would have no problems if this was a static web page, but because I'm using WordPress, this task seems to be more troublesome.

Well, to start off I would remove that gmail account from your info (just to be safe).
Secondly I would advise you to use the sendmail scripts provided by Wordpress.
There are plugins like gravityforms which allow you to make a form and decide all these options without making a static form, nor a new template file for that matter.
You can only change to which page the form will redirect after the refresh (the action will decide that)
If you want it to stay on the same page you can put the page itself in the action and on top put an if statement like
if(isset($_POST['submit'])){
//validation, sendmail, and possibly errors here
}
else{
//show the form
}
anyway, a refreshing webform is as standard as it gets. It's just how it submits things. The only way you could prevent a page is by using jquery or javascript like so: (give your submit an id)
$('#submit').on("click", function(e){
//this prevents any submit functionality (like refresh)
e.preventDefault();
//custom code to get values here and put them in the sendmail function like so:
var message = $('$message').text();
}
Try ajax form submission. And add the insert query in a separate file.

Efficient and effective form validation

I have a working example of a form here. I need to use Javascript of Jquery form validation to verify that the user has inputted his/her own data. So far I have tried to check for values, but obviously this didn't work, because the inputs and textarea already have a default value, and so the user can submit straight away without filling in anything.
Any help would be much appreciated.
Thanks in advance!
EDIT
I am using this php to send the submitted data to an email address:
<?php
$name = $_POST['name'];
if ($name=="") {
$name="Nothing was returned for this part of the form.";
}
$email = $_POST['email'];
if ($email=="") {
$email="Nothing was returned for this part of the form.";
}
$subject = $_POST['subject'];
if ($subject=="") {
$subject="Nothing was returned for this part of the form.";
}
$comments = $_POST['comments'];
if ($comments=="") {
$comments="Nothing was returned for this part of the form.";
}
$theMessage7="<b>Results from the form at www.site.co.uk/contact.html</b><br /><br />" . "Name: " . $name . "<br />" . "Email: " . $email . "<br />" . "Subject: " . $subject . "<br />" . "Message: " . $comments . "<br />";
$theEmail7="mail#mail.com";
$theSubject7="New form submission";
$theHeaders7="MIME-Version: 1.0
Content-type: text/html; charset=iso-8859-1
From: form#bikeinc.co.uk
Subject: New form submission";
$theErrorFile7="www.site.co.uk/12345";
$theThanxFile7="received.html";
if (!(mail($theEmail7, stripslashes($theSubject7), stripslashes($theMessage7), stripslashes($theHeaders7)))) {
header ( "Location: $theErrorFile7" );
}else{
header ( "Location: $theThanxFile7" );
}
?>
The effective form of form validation on user side is to use jQuery validation plugin, see examples on proper usage.
Note: user ALWAYS can disable javascript or use some kind of bot to send invalid not checked data, so you always have to write proper server side validation.
Frameworks often provides effective way of form validation, such as Zend_Validator.
It's common to prepare method for your php application such as:
public function validate() {
if( !isset( $_POST['name'])){
$this->field = 'name';
$this->msg = 'Invalid user name';
return false;
}
...
return true;
}
And use it in both sending script:
if( $form->validate()){
send();
}
And in check script:
$data = array();
if( $form->validate()){
$data['status'] = 'ok';
} else {
$data['status'] = 'failure';
$data['field'] = $form->field;
$data['msg'] = $form->msg;
}
echo json_encode( $data);
End than use jquery and javascript for form validation "on the fly":
<input type="text" name="name" value="" onchange="ajaxValidate();" />
function ajaxValidate(){
// Call ajax to check script and put results
}
If you're just building small project with one form or so, you could implement few methods like:
function is_post( $key); // Shorter than write isset( $_POST[ $key])
function get_post( $key, $defaultValue); // Shorter than isset( $_POST[ $key]) ? $_POST[ $key] : $default
function is_email(...);
...
And jQuery validation:
function validateForm() {
$('.input').removeClass( 'error');
var status = true;
if( $('input[name=name]').val() == '')){
$('input[name=name]').addClass( 'error');
setMessage( 'Name cannot be empty');
status = false;
}
...
return status;
}
<form onsubmit='return validateForm();' ...>
You could try using the HTML5 required attribute... however this will only work with browsers that support it. For example:
<label for="name">Name:</label>
<input type="text" name="name" required="required" id="name">
This will only work if you use the HTML5 doctype though.
Then for the PHP validation in the instance the HTML5 validation hasn't run due to incompatible browser... or if JavaScript doesn't run due to it being disabled/unavailable/broken.
// check input
if (empty($_POST['name']))
{
$errors['name'] = 'Please provide your name.';
}
I then display the errors when I show the page to the user after the authentication has gone through.
<label for="name">Name:</label>
<input type="text" name="name" required="required" id="name">
<?php if (!empty($errors['name'])): ?><p class="error"><?php echo $errors['name']; ?></p><?php endif; ?>
Also... remember to protect yourself from SQL injection, XSS and mallicious code injection if this is going to be saved in a database or displayed to other users.

How would I go about making this error message appear when form field is not right?

I have an if statement and I already have it working so if certain fields are not filled in it will not send. I then have an else, and I put it like so:
if(isset($_POST['submit'])) {
if (!empty($name) && (!empty($email) || !empty($phone))) {
mail( "EMAIL#hotmail.com", "Monthly Specials Email",
"Name: $name
Email: $email
Phone Number: $phone
Comment: $comment", "From: $email" );
$error = "";
} else {
$error = "Please fill in the required fields.";
}
}
In the form, I have a span class like so:
<span class="error">'.$error.'</span>
I have it so the action of the form is set to blank so it will stay on the same page when sent, and all of the functions are in the same page as the form. How would I go about updating the error span?
Thanks so much for any help or tips!
In order to process the form while staying on the page, you will need to incorporate some AJAX. The easiest way to do this is to use a framework of some sort (recommend jQuery). This should give you some insight into how to develop such functionality. If you get stuck, we're here to help.
http://api.jquery.com/jQuery.post/
Following your current model, I am assuming you do not mean AJAX and that you merely mean the server side code and form cohabitate on the same script. You can set the action of the form to $_SERVER['PHP_SELF'] first to ensure the proper action attribute is set.
Are you echoing out the error message within the span, or is all that output being placed after an echo statement?
echo '<span class="error">'.$error.'</span>'
Or, if not in the PHP context outside of script
<span class="error"><? echo $error; ?></span>
Also, you may want to consider using a mature php mailing solution like PHP Mailer to help set headers and ensure more effective delivery.
You don't need any AJAX.
$error = '';
if (isset($_POST['submit'])) {
if ( <<< insert check for required fields >>> ) {
// handle form, send mail, etc
// you may want to redirect on success to prevent double posting
} else {
$error = "Please fill in the required fields.";
}
}
Well without the rest of the page I'm not sure why this isn't working already but you should post back to the same page not just an empty action. I would do it this way.
<?php
$error = $name = $email = $phone = $comment = "";
if(isset($_POST['submit'])) {
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$comment = $_POST['comment'];
if (!empty($name) && (!empty($email) || !empty($phone))) {
mail( "EMAIL#hotmail.com", "Monthly Specials Email",
"Name: $name
Email: $email
Phone Number: $phone
Comment: $comment", "From: $email" );
} else {
$error = "Please fill in the required fields.";
}
}else{ ?>
<div id="specialsForm"><h3>Interested in this coupon? Email us! </h3>
<form method="post" action="emailMonthlySpecials.php">
<span class="error><?php echo $error; ?></span>
Name: <input name="name" type="text" value="<?php echo $name;?>"/><br />
Email: <input name="email" type="text" value="<?php echo $email;?>"/><br />
Phone Number: <input name="phone" type="text" <?php echo $phone;?>"/><br /><br />
Comment: <br/>
<textarea name="comment" rows="5" cols="30"><?php echo $comment;?></textarea><br /><br />
<input type="submit" value="Submit Email"/>
</form></div>
<?php } ?>
When I handle form validations, I tend to create an array to hold the error messages, like so:
<?php
$error = array();
if( $POST ){
# Form is Submitted
if( /* TRUE if "email" is empty */ ){
$error['email'] = 'Please provide an Email Address';
}elseif( /* TRUE if "email" is not a valid address */ ){
$error['email'] = 'Please provide a Valid Email Address';
}elseif( /* TRUE if "email" is already associated with a User */ ){
$error['email'] = 'The Provided Email Address is Already Taken';
}
...
if( count( $error )==0 ){
# No Error has been Recorded
# Do Successful Things
}
} /* Closing if( $_POST ){ */
Then within the presentation/display section, I have something like:
<?php if( count( $error )>0 ){ ?>
<div id="error">
The following Errors have occurred:
<ul>
<?php foreach( $error as $k => $v ){ ?>
<li><?php echo $k; ?>: <?php echo $v; ?></li>
<?php } ?>
</ul>
</div>
<?php } ?>
And within the form, something like:
<input name="email"<?php echo ( $error['email'] ? ' class="error"' : '' ); ?> />
This means that:
Customised, multi-tiered error messages can be recorded.
A summary of the error messages can be shown.
Fields associated with the error messages can be marked.
Has worked well in my experience thusfar.
Yep, I think You have two methods to do that, as already explained above...
When the form is submitted to the same page (itself) using *$_SERVER['PHP_SELF']*, you can check weather each posted field is empty using empty() function. Then if they are not filled then set the variable $error and then use echo $error; at the span of error... If no any error you can assign the default message at the $error instead of the error... It should do what you need...
You can use AJAX and send a request to the page and set the error message. Then the page is not fully refreshed as it was before, but only the element you wanted to refresh. This is fast, but in most of the cases, first method is preferred, unless AJAX is a need..
What exactly you want to do? If you specify what's your actual need, it is possible to provide some sample code... (First method is already discussed)
Thank You.

My suggest is to use ajax call when submit,
according to the answer come back, you update the span of error.
you can find a lot of examples in web like

http://www.the-art-of-web.com/javascript/ajax-validate/
