SQL Query error in PHP - php

Question

This is a code for a cafeteria, and this is the login.
<?php
$userna = 'root';
$paso = '';
$mach = 'localhost';
$db ='cafeteria';
session_start();
// GET PAGES RECORD FROM LOG TABLE: *********| Only the first time though:
if (isset($_SESSION['log']) != 'logging')
{
// Here, just creating a string:
$pages_record = "";
$insert_query = '';
// Get saved pages from the database:
$connection = mysqli_connect($mach,$userna,$paso,$db) or die ("Error in log-page script: AB-1 - query: $insert_query." . mysqli_error($connection));
mysqli_select_db($connection,'cafeteria');
// Query string to pull all pages from table record:
$get_pages_query = "select * from log-page";
// Query the database, and save result:
$query_pages_result = mysqli_query($connection, $get_pages_query);
// Check number of results returned:
$num_of_results = '';
$num_of_results = mysql_num_rows($query_pages_result);
if ($num_of_results > 0)
{
// Loop through the result array: Each time, one row, and then the next one ...
for ($row = 0; $row < $num_of_results; $row++ )
{
// Getting one row:
$get_row = mysqli_fetch_array($query_pages_result);
// Extracting just the page name from the row:
$one_page = substr($get_row["page"],strripos($get_row["page"],"/") + 1);
// Adding this page name to the string created previously:
if ($row == 0)
{
$pages_record .= $one_page;
}
else
{
$pages_record .= ",".$one_page;
}
}
// Once all pages have been read and saved to the string
// now we save it to the session:
$_SESSION['logpages'] = $pages_record;
$_SESSION['log'] = 'logging'; // This just tells us, we are logging pages to the database.
}
else
{
// There are no pages in the table:
$_SESSION['logpages'] = "";
$_SESSION['log'] = 'logging'; // This just tells us, we are logging pages to the database.
}
}
// Check if page is already in session list.
$pages_array = array();
if (strlen(isset($_SESSION['logpages'])) > 0 )
{
// string variable that holds all pages separated by commas:
$pages_string = $_SESSION['logpages'];
// creating an Array to hold all pages already logged in server:
if (strstr($pages_string, ","))
{
$pages_array = explode(",", $pages_string);
}
else // just means there's only one page in the record
{
// so, we push it inside the array.
array_push($pages_array, $pages_string);
}
// current page: [ We are extracting only the page, not the entire url, Exmp: login.php ]
$current_page = substr($_SERVER['PHP_SELF'],strripos($_SERVER['PHP_SELF'],"/") + 1);
// Check if current_page is in the array already:
if (!in_array($current_page, $pages_array))
{
// IF is NOT in the array, then add it:
array_push($pages_array, $current_page);
// Add it to the Session variable too:
$pages_string = implode(",", $pages_array);
// Re-save it to SESSION:
$_SESSION['logpages'] = $pages_string;
// Now, add it to the database table "log-page""
$connection = mysqli_connect($mach,$userna,$paso,$db) or die ("Unable to connect!");
mysqli_select_db($connection,'cafeteria');
// Query to insert page description into the table:
// [ date - time - page - user ]
$insert_query = "INSERT INTO log-page
(`date`, `time`, `page`, `user`) VALUES
('".date("Y-m-d")."', '".date("H:i:s")."', '".$_SERVER['PHP_SELF']."', '".(isset($_SESSION['SESSION_UNAME']))."')";
mysqli_select_db($connection,'cafeteria');
// INSERTING INTO DATABASE TABLE:
mysqli_query($connection, $insert_query) or die ("Error in log-page script: AB-2 - query: $insert_query." . mysqli_error($connection));
// Done!
}
else
{
// IF it IS in the list, just SKIP.
}
}
else
{
// means, that there are absolutely no pages saved in the database, basically this is the first log:
$_SESSION['logpages'] = substr($_SERVER['PHP_SELF'],strripos($_SERVER['PHP_SELF'],"/") + 1);
// Now, add it to the database table "log-page""
$connection = mysqli_connect($mach,$userna,$paso,$db) or die ("Unable to connect!");
mysqli_select_db($connection,'cafeteria');
// Query to insert page description into the table:
// [ date - time - page - user ]
$insert_query = "INSERT INTO log-page
(date, time, page, user) VALUES
('".date("Y-m-d")."', '".date("H:i:s")."', '".$_SERVER['PHP_SELF']."', '".(isset($_SESSION['SESSION_UNAME']))."')";
mysqli_select_db($connection,'cafeteria');
// INSERTING INTO DATABASE TABLE:
mysqli_query($connection,$insert_query) or die ("Error in log-page script: AB-2 - query: $insert_query." . mysqli_error($connection));
// Done!
}
?>
But now i am getting this error:
Error in log-page script: AB-2 - query: INSERT INTO log-page (date,
time, page, user) VALUES ('2012-10-16', '16:58:44',
'/caf/pages/index.php', '').You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the
right syntax to use near '-page (date, time, page, user)
VALUES ('2012-10-16', '16:58:44' at line 1
Im using Xampp 1.8.1 PHP: 5.4.7. It does not let me login neither as administrator nor as a cashier

Answer 1

Enclose the table name in backticks like this (rest of the query omitted):
$insert_query = "INSERT INTO `log-page` (`date`, `time`, `page`, `user`) ... ";
Otherwise MySQL will try to interpret the - as a minus sign, which fails in this case.
EDIT
IN the last insert shown, also the column names should be enclosed in backticks:
$insert_query = "INSERT INTO `log-page` (`date`, `time`, `page`, `user`) VALUES ...";

Answer 2

Try escaping field name
(`date`, `time`, `page`, `user`)

Answer 3

It's been a while since I looked at mySql docs, but it looks to be complaining about the table name "log-page". Try quoting that table name.
