mysql_query不向我的数据库中插入任何内容

Question

I have this bit of code here:

<?php
error_reporting(E_ALL);
include 'DB.php';

$con = mysql_connect($host,$user,$pass)
    or die("Error: ".mysql_error());
$dbs = mysql_select_db($databaseName, $con);

$name = $_POST['name'];
$date = date('Y-m-d');
$amount = $_POST['amount'];
$timPaid = $_POST['timPaid'];
$rennyPaid = $_POST['rennyPaid'];

$sql = "INSERT INTO $tableName (`name`, `date`, `amount`, `timpaid`, `rennypaid`)
        VALUES ('$name', '$date', '$amount', '$timPaid', '$rennyPaid')";

$result = mysql_query($con, $sql)
    or die("Error: ".mysql_error());

mysqli_close($con);
?>

DB.php is my database settings. I call a query to it on page load and it connects and pulls data fine, so I know it's not an issue there. I also don't get any errors. I get a status code 200 OK on the post.

Here's the ajax post:

var name = $('#name').val();
var amount = $('#amount').val();
var timPaid = $('#timPaid').val();
var rennyPaid = $('#rennyPaid').val();
var data = $('#newSubmissionForm').serialize();

$.ajax({
    url: 'insert.php',
    data: data,
    type: 'post',
    success: function()
    {
        window.location.href = '';
    }
 });

Does it have something to do with me serializing it?

I hope this is enough info. Thanks!

Answer 1

mysql_query requires first parameter as query and second parameter as connection object (optional)

change this

$result = mysql_query($con, $sql);

to

$result = mysql_query($sql, $con);

Also you used mysql for connection and query but you used mysqli to close the connection.

Answer 2

You have likely just switched the $sql and $con statement. in mysql_query $sql should be the first parameter. It's easy to forget, since mysqli_query should have $con as the first. :/

php die() statement is the same as exit, and will end the script with status 200. Likely you DO get an error in the output. Try viewing it in eg developer console (Chrome)

Answer 3

1. check in internet explorer which code is generated (inspect element)
2. add to the beginning of your session php file

 <?php echo '<pre>'; var_dump($_POST); die(); ?> 

This will show the values that are sent to the database.
