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
}

I am learning PHP through w3schools. I am little bit confused of the execution flow of the page. I will attach a code example from w3schools.

Can anyone explain how the execution flow goes on this form handling. Browser can't run the php script. In this example superglobal $_SERVER["PHP_SELF"] used to refer the same html page. when we try to submit the page with empty field it shows the error message in screen. This is happening due to the fact php variable got its error value after submission. I think that after triggering the submit button. This page makes a request to the same page in the server using POST method and in the server we access the same form value using superglobal $_POST["name"],["email"] etc.. and finally the server throws the new html page. Am i right? or this validation is happening entirely in the frontend.
In php the validation is happening entirely in the server ..
The frontend only validate things when JavaScript involved or you add field attributes like required , min , max.
I think w3 is good source to check small code snippets. but it's not good source to learn
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:
<!DOCTYPE HTML>
<html>
<head>
<style>
.error {color: #FF0000;}
</style>
</head>
<body>
<?php
// define variables and set to empty values

$name = $email = $gender = $comment = $website = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (empty($_POST["name"])) {
$nameErr = "Name is required";
} else {
$name = test_input($_POST["name"]);
// check if name only contains letters and whitespace
if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
$nameErr = "Only letters and white space allowed";
}
}
if (empty($_POST["email"])) {
$emailErr = "Email is required";
} else {
$email = test_input($_POST["email"]);
// check if e-mail address is well-formed
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$emailErr = "Invalid email format";
}
}
if (empty($_POST["website"])) {
$website = "";
} else {
$website = test_input($_POST["website"]);
// check if URL address syntax is valid (this regular expression also allows dashes in the URL)
if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&##\/%?=~_|!:,.;]*[-a-z0-
9+&##\/%=~_|]/i",$website)) {
$websiteErr = "Invalid URL";
}
}
if (empty($_POST["comment"])) {
$comment = "";
} else {
$comment = test_input($_POST["comment"]);
}
if (empty($_POST["gender"])) {
$genderErr = "Gender is required";
} else {
$gender = test_input($_POST["gender"]);
}
}
function test_input($data) {

return $data;
}

<h2>PHP Form Validation Example</h2>
<p><span class="error">* required field</span></p>
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">

value="other">Other
<span class="error">* <?php echo $genderErr;?></span>
<br><br>
<input type="submit" name="submit" value="Submit">
</form>
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 new to php coding and have been told by others that I need to be using parameterized queries/prepared statements for my php scripts and MySQL database. I've looked at other examples of scripting these prepared statements and they usually refer to user login functions. My query is just a web form to capture user inputted data and store in database (SQL insert as opposed to SQL select). I am hoping someone can help me with how to script the php to prevent sql injections. Also hoping someone can let me know whether these prepared statements should also be used in php SQL Select scripts where I am only displaying database records on a form. Thanks in advance!
Here are the two php files I am using, the first is my database connection script:
<?php
DEFINE ('DB_USER', 'fakeuser');
DEFINE ("DB_PSWD", 'fakepassword');
DEFINE ('DB_HOST', 'localhost');
DEFINE ('DB_NAME', 'newspaper');
$dbcon = mysqli_connect(DB_HOST, DB_USER, DB_PSWD, DB_NAME);
?>

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!

$newrecord = "1 record added to the database";
} // end of main if statement
?>
<?php
echo $newrecord
?>
</body>
</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 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.
