I am trying to set up a form for my website that is all on 1 php page (contact.php). I have went through the tutorial on w3schools and have gotten the form validation working perfectly. However, it does not send the form information anywhere. I have researched other form articles and tutorials, and although I can get some forms to email, they dont validate, and vice versa. I have tried combining this info, but it does not work.
Can someone please help me to get this code to send the form data to an email address?
Thank you.

I am creating a php form for data validation but there are some errors that I can't find.
When I submit the form the required notification is displayed. But when I reload the page then the required notification still remains. My code is:

This is the result when I first type the address in the browser.
This is the result when I enter an empty value in all the fields and submit the form. This will remain when I reload the page and until I close the browser tab and open a new tab and enter the url again.
You got error message when you reload after form submission. Try following code into your JS file or in JS code.
<script>
if ( window.history.replaceState ) {
window.history.replaceState( null, null, window.location.href );
}
</script>
Hope this will help you!
I'm recieving an issue in the following php code. I am recieiving an unknown variable error in line 146, (echo $newrecord) variable. I'm not sure what is wrong with this variable, I have defined it in the IF statement, and am simply echoing if it is successful. I originally had that segment of code (after ) at the top of the script, but it was causing issues with the mandatory field error messages displaying properly. Any help is appreciated!

</html>
newrecord is defined and initialized inside the if statement, therefore if your code opts to the else, it will skip the if and your newrecord variable won't exist.
$newrecord is defined within an if statement, when the if is not executed the variable is not available. You can define it by default adding $newrecord = ''; before you start the if for the submit.
I have a form with 3 fields, and I want to validate the fields.
Let's say that the user make a mistake or didn't introduce the email, then all other fields (name and Address) reset to blank.
Is there any way to show the error Message (Email is required) without resetting the name and address so the user doesn't have to introduce all values again?
This is a great help for user the form has multiple values.
Thank you so much

You can use value="<?php echo $name;?>" for name field because you already define $name variable.You can use $email and $address variable for email and address field respectively
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<input type="text" name="name" placeholder="First Name" value="<?php echo $name;?>">
<span class="error">* <?php echo $nameErr;?></span>
<br><br>
<input type="text" name="email" placeholder="Email" value="<?php echo $email;?>">
<span class="error">* <?php echo $emailErr;?></span>
<br><br>
<input type="text" name="address" placeholder="Address" value="<?php echo $address;?>">
<span class="error">* <?php echo $AddressErr;?></span>
<br><br>
<input type="submit" name="submit" value="SAVE">
</form>
The easiest way via PHP would look like:
<input type="text" name="name" placeholder="First Name" value="<?php echo ( isset( $_POST['name'] ) ? htmlspecialchars($_POST['name']) : '' ); ?>">
This code checks if POST[name] has been send to the server and if so, it simply sets the content as value for the input.
For the other inputs you have to replace $_POST[name] with e.g. $_POST[email].
Also I would set the input type to email, for the e-mail-address.
I would like to validate the information before its send it to me. For instance that an email address has an # on it.
I have the following code to introduce: Name, LastName and email. I validated it that they are not empty, but:
How do I send a message to the user to let them know that they need to fill it up? I tried: if ($nameErr == ''){echo "Need to introduce a name"}
but it doens't work
How do I make validation of type: making sure that email address has an # or that a telephone is numeric and has 9 digits?

you don't actually need to code all validation yourself. It is more convenient if you use a library like http://respect.github.io/Validation/ this.
I'm using this code from W3 (http://www.w3schools.com/php/php_form_complete.asp) to make server side validation for given example form.

Although server side validation works fine,I can't put mail() function to work ONLY WHEN both $name (treated as subject) and $comment (treated as message) fields are filled.
I've tried many combinations but email is always submitted even when fields are empty.
So my question is: how to make this validated form send email only when $name and $comment fields are filled and validated?
As you are creating $nameErr when the name is invalid and $comment is an empty string when the comment is valid you can use the following conditional:
if (!$nameErr && $comment) {
}
Empty strings are considered FALSE:
http://php.net/manual/en/language.types.boolean.php
You can always use flags.
<?php
....
// let's say there are some flags for validation
if($flag1 && $flag2 && .. $flagN){
// perform email sending here
}
?>
Or you can use the default error message variables; check if they are empty
<?php
if(!empty($nameErr) && !empty($comment)){
// perform email sending
}
?>
Do the validation after you validated $name and $comment:
if($nameErr == "" && $emailErr == "") { // If they are empty, no errors where found
// Do your email validation here
}
