Question

THE MISSING _ WAS A TYPO ON STACKOVERFLOW, I WAS TESTING.

I’m trying to insert a value to my database using the following two files:

Add Record:

 <form action="AddVenue.php" method="post" />
<p>Venue Name: <input type="text" name="venue_name" /></p>
<p>Venue Capacity: <input type="text" name="venue_capacity" /></p>
<input type="submit" value="Submit" />
</form>

AddVenue.php

<?php
require("dbconnection.php"); // Connect to Database

// Select Database

$db= 'database';  
mysql_select_db($db) or die("Could not select database");


$venue_name = $_POST['venue_name'];
$venue_capacity = $_POST['venue_capacity'];

$sql = "INSERT INTO Venues (venue_name) VALUES ('$venue_name')";
$sql = "INSERT INTO Venues (venue_capacity) VALUES ('$venue_capacity')";

if (!mysql_query($sql))
{
       die('Error: ' . mysql_error());
}



mysql_close();
?>

At the moment, it adds the to the field venue_capacity without fault, however it always adds NULL to the venue_name field. The capacity field is an INT, and the name field is VARCHAR.

I have no idea why it’s doing it, they are the same a pat from the names, which I have double and triple checked. Does anyone have any ideas?

Answer 1

You are resetting $sql with a new query without performing it first.

You should combine the two queries into one:

INSERT INTO Venues (venue_name, venue_capacity) VALUES ('$venue_name', '$venue_capacity');

Your form also needs to have the field named venue_name instead of venuename.
