How to insert to database using php? - php

Question

I'm very new to php and I really want to learn it. I'm learning from w3school, but I can't manage to do this (saving to database)... I also tried specifying the values in the .php and managed not to get error but it did not save in the database. Please tell me what is wrong in this.
<form action="submit.php" method="POST">
<p>Name:<input type="text" name="name"/></p>
<p>Email:<input type="text" name="email"/></p>
<p>Message:<textarea rows="3" cols="1" name="message"></textarea></p>
Submit
</form>
PHP File
<?php
$con = mysqli_connect("localhost","root","","kellywood");
if (mysqli_connect_errno()) {
echo "Failed to connect to Database";
} else {
echo "Connected";
}
$sql = "INSERT INTO kellywood (messages.name, messages.email, messages.message) VALUES ('$_POST[name]','$_POST[email]','$_POST[message]')");
if (!mysqli_query($con,$sql)) {
die('Error: ' . mysqli_error($con));
}
mysqli_close($con);
?>
No error, and I specified the values but it did not save in the database.
<?php
$con = mysqli_connect("localhost","root","","kellywood");
if (mysqli_connect_errno()) {
echo "Failed to connect to Database";
} else {
echo "Connected";
}
mysqli_query($con,"INSERT INTO kellywood(messages.name, messages.email, messages.message) VALUES ('Peter', 'Griffin',35)");
mysqli_close($con);
?>
Sorry for the noob question but i'm very new in php... Please help

Answer 1

There are a few things that are incorrect.
First:
Submit
which should be a button and not a link:
<input type="submit" name="submit" value="Submit">
And based on a comment that was made: "database is kellywood, messages is the table."
This:
mysqli_query($con,"INSERT INTO kellywood(messages.name, messages.email, messages.message)
VALUES ('Peter', 'Griffin',35)");
Should be:
mysqli_query($con,"INSERT INTO messages (name, email, message)
VALUES ('Peter', 'Griffin',35)");
However and based on your input variables, it should resemble more like this:
mysqli_query($con,"INSERT INTO messages (name, email, message)
VALUES ('" . $name . "', '" . $email . "', '" . $message . "')");
While assigning your input variables such as:
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
Rewrite:
<?php
$con = mysqli_connect("localhost","root","","kellywood");
if (mysqli_connect_errno()) {
echo "Failed to connect to Database";
} else {
echo "Connected";
}
$name = $con->real_escape_string($_POST['name']);
$email = $con->real_escape_string($_POST['email']);
$message = $con->real_escape_string($_POST['message']);
mysqli_query($con,"INSERT INTO messages (name, email, message)
VALUES ('" . $name . "', '" . $email . "', '" . $message . "')");
mysqli_close($con);
?>
Or you can use:
<?php
$con = mysqli_connect("localhost","root","","kellywood");
if (mysqli_connect_errno()) {
echo "Failed to connect to Database";
} else {
echo "Connected";
}
$name = $con->real_escape_string($_POST['name']);
$email = $con->real_escape_string($_POST['email']);
$message = $con->real_escape_string($_POST['message']);
$sql = "INSERT INTO messages (name, email, message)
VALUES ('" . $name . "', '" . $email . "', '" . $message . "')";
if (!mysqli_query($con,$sql)) {
die('Error: ' . mysqli_error($con));
}
else {
echo "SUCCESS!";
}
mysqli_close($con);
?>
HTML form
<form action="submit.php" method="POST">
<p>Name:<input type="text" name="name"/></p>
<p>Email:<input type="text" name="email"/></p>
<p>Message:<textarea rows="3" cols="20" name="message"></textarea></p>
<input type="submit" name="submit" value="Submit">
</form>
Both of the above worked on my server, using VARCHAR(255) for all 3 columns.
Columns: name - email - message

Answer 2

Try using a button type="submit", instead of the href tag.
