I am a beginner in html, and I am beginning to develop my first website. I watched a video to learn to code a commentary system, here is the link:
https://www.youtube.com/watch?v=O4BkHj7Ws9U
My page does resemble what is shown in the video, but there is some errors, take a look at my webpage after watching the video, as you can see, there are errors:
Here is my code:
<HTML>
<form action="" method="post">
<label> Name: <br><input type="text" name="name"><br></label>
<label> Message: <br><textarea cols="35" rows="5" name="mes"></textarea></label><br>
<input type="submit" name="post" value="Post">
</form>
</HTML>
<?php
$name = $_POST["name"];
$text = $_POST["mes"];
$post = $_POST["post"];
if ($post){
#WRITE DOWN COMMENTS#
$write = fopen("com.txt", "a+");
fwrite($write, "<u><b> $name</b></u><br>$text<br></br>");
fclose($write);
#DISPLAY COMMENTS#
$read = fopen("com.txt", "r+t");
echo "All comments:";
while(!feof($read)){
echo fread($read, 1024);
}
fclose($read);
}
else{
#DISPLAY COMMENTS#
$read = fopen("com.txt", "r+t");
echo "All comments:<br>";
while(!feof($read)){
echo fread($read, 1024);
}
fclose($read);
}
?>
Thank you for your help, sorry, I'm sort of a newbie at this.
You should use something like MAMP to run php code.
Or upload everything to a webserver.
You have to save your file as a PHP file.

So, from what I have been learning for these past few weeks I believe I have sufficient knowledge on how to perform PHP, and SQL related queries to create a good and dynamic website that could support something like a forum. I've not been able to do that yet, and am having quite a bit of trouble with it as well. So far, I've made a PHP file, that was simply to see if I could use PHP well. It did not work out, and I've been getting plenty of errors, and I've been unable to fix them, whatsoever. And so, I'd like to come here to ask, if anyone out there could possibly analyze my code that I've written, and see what is wrong with it, if possible. Along with that, I'd like to know what would be the "Proper" way of
A. Connecting to SQL
B. Selecting Data
C. Displaying/Utilizing Data
And thank you, for reading and/or possibly replying to this.
Here, is the code I've written but have been unable to work.
<?php
include 'header.php';
include 'connect.php';
?>
<body>
<form>
Input First name:<br>
<input type="text" name="FN">
<br>
Input Last name:<br>
<input type="text" name="LN">
<br>
Input Email:<br>
<input type="text" name="Email">
<br>
<input type="submit" method="post">
<?php
if (isset($_POST['FN'], $_POST['LN'], $_POST['Email']))
$sql = 'INSERT INTO `info` ("USERID", "FN", "LN", "Email") VALUES (\'$_POST[FN]\', '$_POST["LN"]', '$_POST["Email"]')';
?>
</form>
<?php
$sql = "SELECT FN, LN, Email
FROM
info"
$result = "mysql_query($sql)"
while($row_list = mysql_fetch_assoc( $result )) {
ECHO <div>The Names are:</div><br>
ECHO $FN . "," . $LN . "," . $Email;
}
?>
</body>
</html>
Your PHP code is wrong in so many ways even in your query. What I did is clean your codes.
<?php
include 'header.php';
include 'connect.php';
?>
<body>
<form action="" method="POST">
Input First name:<br>
<input type="text" name="FN">
<br>
Input Last name:<br>
<input type="text" name="LN">
<br>
Input Email:<br>
<input type="text" name="Email">
<br>
<input type="submit" name="submit-btn" value="submit">
</form>
<?php
if (isset($_POST['submit-btn'])){
$sql = 'INSERT INTO info ( "FN", "LN", "Email") VALUES ('$_POST[FN]', '$_POST["LN"]', '$_POST["Email"]')';
if (mysql_query($sql)) {
echo "New record created successfully";
}
}
$sql = "SELECT FN, LN, Email FROM info";
$result = mysql_query($sql)
while($row_list = mysql_fetch_assoc( $result )) {
ECHO '<div>The Names are:</div><br>';
ECHO $FN . "," . $LN . "," . $Email;
}
?>
</body>
</html>
try to indent your code to make it more readable for yourself.
as already answered by user3814670, your insert query was wrong, with 4 elements (id,fn,ln,email) and only 3 data (fn,ln,email)
your query was't being executed also cleaned by user3814670 by adding the lines
if (mysql_query($sql)) {
echo "New record created successfully";
}
try to print your query to the screen and executing it in you database to see if your query fails or print the error to screen
mysql_error()
add this on top of your file after
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
Here's how you display data from the database using while loop
while($row=mysql_fetch_array($result)) {
echo $row['FN'] . " " . $row['LN'] . " " . $row['Email'];
}
how to Load Text file into HTML, inside tag?, I don't have an source to show you.
thanks
You can use PHP to load files from the user's computer. Here is an example.
form.html
<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
upload.php
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
if(isset($_POST["submit"])) {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
header("Location: http://example.com/displaymessage.php?filename=" + basename( $_FILES["fileToUpload"]["name"]));
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
displaymessage.php
<?php
$file = $_GET['filename'];
?>
<script>
var client = new XMLHttpRequest();
client.open('GET', '/uploads/<?=$file?>');
client.onreadystatechange = function() {
document.getElementById("#textbox").value = client.responseText;
}
client.send();
</script>
Make sure to change #textbox, to the ID of the textarea tag. (e.g. <textarea id="foo">)
NOTE: I just came up with half of this code, and I am not sure if it will work
I'm having some problems with getting data from HTML fields. This is how it looks in HTML
<form action="getInfo.php">
<span>Series</span>
<input class="searchFieldAlign" type="text" name="seriesName" /><Br>
<span>Volume</span>
<input class="searchFieldAlign" type="text" name="volumeName" /><Br>
<span>Nr</span>
<input class="searchFieldALign" type="text" name="issueNR" /><Br>
<p input class="searchFieldALign" type=submit></p>
</form>
This is my php script:
<?php
$seriesName = mysqli_real_escape_string($conn, $_POST['seriesName']);
$volumeName = mysqli_real_escape_string($conn, $_POST['volumeName']);
$issueNR = mysqli_real_escape_string($conn, $_POST['issueNR']);
$con=mysqli_connect("localhost","user","psswd","db");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$qryIssueInfo = mysqli_query($con,"select issueNR, issueVolume, issueName, issueImageURL from issue, series where (seriesName='$seriesName') and (issueVolume='$volumeName') and (issueNR=$issueNR)");
$rowIssueInfo = mysqli_fetch_array($qryIssueInfo);
The problem is I don't get output from my query. There are no problems if i change it to this:
$qryIssueInfo = mysqli_query($con,"select issueNR, issueVolume, issueName, issueImageURL from issue, series where seriesName='Buffy, the Vampire Slayer' and issueVolume= 'Season 8' and issueNR=1");
If you not set form method = "post" it will be "get" and you should $_GET.
To correct:
<form method="post" action"getInfo.php">
Take it easy
The first version does not contain the apostrophes around the variables.
You should also consider security issues, like SQL injection.
I have a fairly basic email form
<form name="contactform" method="post" action="send_email.php" id="email_form">
<div class="ContactHeaders">Name</div>
<input type="text" name="Name" class="ContactBoxes" id="name"/><br/><br/>
<div class="ContactHeaders">Email</div>
<input type="email" name="Email" class="ContactBoxes"/><br/><br/>
<div class="ContactHeaders">Message</div>
<div style="width:100%">
<textarea name="Message" maxlength="1000"></textarea><br/>
</div>
<div style="width: 100%">
<input type="submit" class="Submitbtn" value="Submit">
</div>
</form>
Here's 'send_email.php'
<?php
ob_start();
include 'navbar.php';
ob_end_clean();
if(isset($_POST['Email'])) {
//declare variables
$Name = $_POST['Name'];
$Email = $_POST['Email'];
$Message = $_POST['Message'];
$complete = 0;
$email_to = "someone#example.com";
$email_subject = "Website Contact";
//check all forms are filled in correctly
$email_exp = '/^[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(preg_match($email_exp,$Email)) {
$complete++;
}
$string_exp = "/^[A-Za-z .'-]+$/";
if(preg_match($string_exp,$Name)) {
$complete++;
}
if(strlen($Message) > 20) {
$complete++;
}
//send email if $complete = 4
if ($complete == 3){
if (get_magic_quotes_gpc()) {
$Message = stripslashes($Message);
}
$Message = $Message . "\n\n" . "From " . $Name;
$headers = 'From: '.$Email."\r\n".
'Reply-To: '.$Email."\r\n" .
'X-Mailer: PHP/' . phpversion();
#mail($email_to, $email_subject, $Message, $headers);
echo '<script>
alert("Thank you for contacting me. I will be in touch shortly");
top.location="index.php";
</script>';
}
else {
echo '<script>
alert("The form you submitted is invalid. Please ensure the following: \n You have provided a valid email address. \n Your phone number is entered correctly. \n The message box contains at least 20 characters.")
history.go(-1)
</script>';
}
}
?>
So my problem is that when the form submits to the php file, the browser loads the php file, runs the code and returns the result (It's not really a problem but it's something I don't want) It is then up to java to display the alert and go back one (in my code anyway). Is there a way to make it run the code in the background so the form runs the php file without having to go to it (if that makes sense) and return the result in the same window. I've obviously looked around and found loads of things about AJAX but I didn't really understand it and couldn't get it to work for me.
The reason for doing this is a little complicated but would make things much easier as far as user-friendliness goes for my site, as well as looking cleaner (going to a blank page and displaying an alert doesn't look very good).
Thanks in advance for any help you can offer me:)
$('.Submitbtn').click(function(e) {
e.preventDefault();
// do some form validation here
if form is valid { // from validation above
var formData = $('#email_form').serialize();
$.post('send_email.php',{data:formData});
} else {
alert('Form no good - fix it!');
return false;
}
});
Here's something you can start with. This is very basic but supplies the necessary foundation for beginning your AJAX adventure.

I know there are thousands and thousands of ways to utilize the PHP mail() function, but I am fairly new to PHP and could use some pointers to get me set in the right direction. I have a PHP mail function written into my WordPress driven site and it emails all the information (name, email, & phone) except for the message field. I've done my research on here as well as every PHP related site, but I would prefer to understand my specific issue so I can better understand what I'm writing. So with that said...here's the code:
<?php
function spamcheck($field)
{
$field=filter_var($field, FILTER_SANITIZE_EMAIL);
if(filter_var($field, FILTER_VALIDATE_EMAIL))
{
return TRUE;
}
else
{
return FALSE;
}
}
if (isset($_POST['email']))
{
$mailcheck = spamcheck($_POST['email']);
if ($mailcheck==FALSE)
{
$submit_message = "Please input your information again.";
}
else
{
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];
mail("emailaddress#gmail.com", "From: $name", "Email: $email", "Phone Number: $phone", "Message: $message");
$submit_message = "Thank you for your message";
}
}
?>
And the HTML...
<form name="message-me" id="contact-form" action="<?php echo $_SERVER['REQUEST_URI']; ?>" method="POST" enctype="multipart/form-data">
<div class="field-group">
<label>Name:</label><input type="text" name="name" id="form_name" />
</div>
<div class="field-group">
<label>Email:</label><input type="text" name="email" id="form_email" />
</div>
<div class="field-group">
<label>Phone:</label><input type="text" name="phone" id="form_phone" />
</div>
<div class="field-group">
<label>Message:</label><textarea rows="4" cols="31" name="message" id="form_message"></textarea>
</div>
<div class="field-group">
<input type="image" src="<?php bloginfo('template_directory'); ?>/images/Send-Message-Arrow.png" width="90" height="72" class="form-button" />
</div>
</form>
Any information would be greatly appreciated. As I mentioned, I'm still learning PHP and I really want to understand what I'm writing - not just blindly copying & pasting code all the time. Thanks!
Your SMTP want to be configured, first check up that
and
//Header Information for mail
$headers = "YOUR HEADERS INFORMATION HERE";
$msg="Email: $email<br/>Phone Number: $phone<br/>Message: $message";
mail("emailaddress#example.com", $subject, $msg, $headers);
Please have look at Documentation.
You need to provide parameters as
mail($to, $subject, $message, $headers);
Here you have provided "to" email address right.
So this might help you:
$message = $_POST['message'];
//Give mail a subject
$subject = "YOUR SUBJECT HERE";
//Header Information for mail
$headers = "YOUR HEADERS INFORMATION HERE";
mail("emailaddress#gmail.com", $subject, $message, $headers);
$submit_message = "Thank you for your message";
Enjoy!
Kindly read this manual with the directives and examples on it and you'll understand well what you are doing. Just take your time to read and understand well then start asking your questions from that point. Right now, you don't seem to understand even how the PHP mail() works. Read then get back so together you'll understand any solutions pointed out to you and you won't just copy and paste the solution without being able to solve it tomorrow.
