around this issue It seems you are a newbie.. Start with mysqli or pdo extensions. Visit W3schools.com for a detailed explanantion with examples. Below is an example of how to use mysqli to connect and insert a row in your database
code :
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());

$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john@example.com')";

if (mysqli_query($conn, $sql)) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . mysqli_error($conn);

    $value = 10;
    $sql = 'SELECT * FROM `table_name` WHERE `column_name` = $value';
    echo $sql;
SELECT * FROM `table_name` WHERE `column_name` = $value
    $value = 10;
    $sql = "SELECT * FROM `table_name` WHERE `column_name` = $value";
    echo $sql;
 SELECT * FROM `table_name` WHERE `column_name` = 10
    $value = 10;
    $sql = "SELECT * FROM `table_name` WHERE `column_name` = '$value'";
    echo $sql; 
SELECT * FROM `table_name` WHERE `column_name` = '10'

like below fixes the issue I have this form to input data into a MySQL database. It's not giving me any errors, but also not inserting data. I have looked around the web, with no avail. I'm not sure if it's my code or maybe I've misconfigured my database. Here's all the code. , Try to change the mysql_query to show errors meaningfully:
code :
mysql_query($sql, $sql_connection) or die(mysql_error() . "<br/>Query was: " . $sql);

will be helpful for those in need You don't get errors because you don't check for them. Your SQL queries are failing because you do not have quotes around your string values.
code :
$query  = $dbh->prepare("INSERT INTO client VALUES (NULL, $uid, '$fname', '$lname', $age, $living, NULL, NULL, NULL)");

$query  = $dbh->prepare("INSERT INTO relationship VALUES (NULL, $uid, $cID, '$relationship', '$dmn', '$dmtel') ");

$query = $dbh->prepare("INSERT INTO address VALUES (NULL, $cID, '$address', '$city', '$state', $zip, NULL, NULL)");

wish helps you 1) Disease_ID should be an auto-incremental primary index column in your MySQL so should not be referenced directly by the HTML output. When inserting a row in the database this value will be self-generating and unique.
2) Check your syntax. Your error log should be mysqli_error($conn) <== you need to specify the connection variable. This goes for most actions using MySQLi procedural. Ask yourself how does the command know which database to apply the action to?
code :
mysqli_connect('localhost','root','', 'tool');
mysqli_query($conn,$sql) or die("error: ".mysqli_error($conn));
<form method="post">
<input value="whatever" name="myName">
$_POST['myName'] = "whatever";

This might help you the problem comes from your check if($caption = '') and if($gallery = '') . Because = is an assignment operator, not comparison. It will assign your $caption to '' and the result of blank caption is expected. You should change to if($caption == '') and if($gallery == '')
