I am new to PHP and haven't worked much on it. I am working on a page where I need to save data from a textbox to a table on submit of a button. But somehow nothing seems to be working on press of button click.
Following is my code for the page:
<?php
require_once('auth.php');?>
<?php
if(isset($_POST['formSubmit']))
{
$errorMessage = "";
if(empty($_POST['category'])){
$errorMessage .= "<li>You forgot to enter a Category!</li>";
}
$varCategory = $_POST['category'];
if(empty($errorMessage)) {
require_once('config.php');
$conn = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_DATABASE)
or die ('Cannot connect to db');
$result = $conn->query("insert into category (name) values ('".$varCategory."')");
}
}
?>

$result = $conn->query("select catid, name from category");
echo "<select name='id'>";
while ($row = $result->fetch_assoc()) {
unset($id, $name);
$id = $row['catid'];
$name = $row['name'];
echo '<option value="'.$id.'">'.$name.'</option>';
}
echo "</select>";
?>
</td>
<td><a href="member-profile.php">Delete</a></td>
</tr>
</table>
</td>
</tr>
</table>
</body>
</html>
if($_POST['formSubmit'] == "Submit")
应该
if(isset($_POST['formSubmit']))
Change this
if($_POST['formSubmit'] == "Submit") // this condition will never true
to
if($_POST['formSubmit'] == "Save")
OR
if(isset($_POST['formSubmit']))
Also remove die
and exit
from here
echo "working"; //die; // your insert query will never execute because you placed die here
$result = $conn->query("insert into category (name) values ('".$varCategory."')");
//exit;
if you have a connection class named auth.php file with function query() then you can use this:
$sql = "insert into category(name) values('".$varCategory."')";
$conn->query($sql);
