'$Customer Username'

there is your probleme in your insert... should be

'$CustomerUsername'

adamdyer · August 22, 2007

hmm! just tried that and its still the same :-S

MadTechie · August 22, 2007

change to

$sql = "INSERT INTO `Booking Database` (`Customer Username`, `Booking ID`, `Check In`, `Check Out`, `Price Cat`, `Type Of Room`, `Password`) VALUES ( '$CustomerUsername', '$BookingID', '$CheckIn', '$CheckOut', '$PriceCat', '$TypeOfRoom', '$Password' )";

can you post the form and the $_GET['CustomerUsername'] part if this fails

MadTechie · August 22, 2007

Opps last code was wrong..!

use

$sql = "INSERT INTO `Booking Database` (`Customer Username`, `Booking ID`, `Customer Name`, `Check In`, `Check Out`, `Price Cat`, `Type Of Room`, `Password`) VALUES ( '$CustomerUsername', '$BookingID', '$CustomerName', '$CheckIn', '$CheckOut', '$PriceCat', '$TypeOfRoom', '$Password' )";

Still need to see the

$CustomerUsername = $_GET[

and the CustomerUsername part of the form

adamdyer · August 22, 2007

yay! that bit worked :-D (thank F*^K for that)

ive still got lots of other things im stuck on though, do you think you'll still be able to help me? its cool if you cant though :-) youve done enough already.

MadTechie · August 22, 2007

Sure:)

adamdyer · August 22, 2007

cool, thanks :-)

Ok, so next part of my problem is such - I have to be able to retreive the data from my Database so that the customers are sorted into two seperate fields of £40 and £60.

PHP Coding

<html>
<head>
<title>View Customers by category</title>
</head>
<body>

<?php 

#get the Customer Price Category i.e. Acat variable
$Cat = $_GET['Acat'];

#--------------------------------------------------------

echo("<font face=Courier size=3>");
echo("<p>Customer Price Category Results for :$CAT <hr></P>");
$VariableName = $_GET['VariablePassed'];
#--------------------------------------------------------

# connect to MySQL
$conn = @mysql_connect("localhost","ajdref","ref2")
or die ("sorry - could not wont connect to MySQL"); 

# select the specified database
$rs = @mysql_select_db("ajdref", $conn)
or die ("sorry - could not connect to the ajdref");

#create the query - sets $sql to contain the required query
$sql = 'SELECT * FROM `Booking Database` ORDER BY `Booking Database` . `Price Cat` ASC LIMIT 0, 30 '; 

#execute the query - uses the mysql_query() function to issue the $sql query to the $conn connection
#$rs contains the result set in the form of an array
$rs = mysql_query($sql,$conn);

?>



</body>
</html>

HTML Coding

<HTML>
<HEAD>
<TITLE> Search by category </TITLE>
</HEAD>
<BODY BGCOLOR=lemonchiffon >

<form NAME="GetCode" ACTION="customerpricecategory2.php" METHOD=get>

  <div align="center"><b><font size="4"> Search by Price Category</font></b></div>
      
  <p></p>
                    
  <div align="center">
    <p>Please choose price category from this list. 
      <select name="Acat">
          <option value="A" selected>A - £40 </option>
          <option value="B">B - £60 </option>
      </select>
    </p>  
  </div>
  
  <p></p>
                  
  <div align="center">Now click 'Send'. 
    <input type="submit" value="Send" name="SUBMIT" >
  </div>
</form>
</BODY>
</HTML>

MadTechie · August 23, 2007

OK from here, we're use the WHERE clause

<?php
//$VariableName = $_GET['VariablePassed'];
$Acat = $_GET['Acat ']; //Acat  being the form element name were passing
#--------------------------------------------------------

//...snip...//

#create the query - sets $sql to contain the required query
//$sql = 'SELECT * FROM `Booking Database` ORDER BY `Booking Database` . `Price Cat` ASC LIMIT 0, 30';
$sql = 'SELECT * FROM `Booking Database` ORDER BY `Price Cat` WHERE  `Price Cat` = $Acat LIMIT 0, 30';
?>

adamdyer · August 23, 2007

do you mean to replace the red SQL with the yellow SQL?

MadTechie · August 23, 2007

i have commented out the lines

//$VariableName = $_GET['VariablePassed'];
//$sql = 'SELECT * FROM `Booking Database` ORDER BY `Booking Database` . `Price Cat` ASC LIMIT 0, 30';

and replaced them with

$Acat = $_GET['Acat ']; //Acat  being the form element name were passing
$sql = 'SELECT * FROM `Booking Database` ORDER BY `Price Cat` WHERE  `Price Cat` = $Acat LIMIT 0, 30';

Basically the 'Acat' is the element in the form (thus the new GET) and

i am selecting the records where `Price Cat` = $Acat (field `Price Cat` = the value of the Acat field)

adamdyer · August 23, 2007

ok done that - so my coding now looks like

<html>
<head>
<title>View Customers by category</title>
</head>
<body>

<?php 

#get the Customer Price Category i.e. Acat variable
$Cat = $_GET['Acat'];

#--------------------------------------------------------

echo("<font face=Courier size=3>");
echo("<p>Customer Price Category Results for :$CAT <hr></P>");
$Acat = $_GET['Acat ']; //Acat  being the form element name were passing
#--------------------------------------------------------

# connect to MySQL
$conn = @mysql_connect("localhost","ajdref","ref2")
or die ("sorry - could not wont connect to MySQL"); 

# select the specified database
$rs = @mysql_select_db("ajdref", $conn)
or die ("sorry - could not connect to the ajdref");

#create the query - sets $sql to contain the required query
$sql = 'SELECT * FROM `Booking Database` ORDER BY `Price Cat` WHERE  `Price Cat` = $Acat LIMIT 0, 30';

#execute the query - uses the mysql_query() function to issue the $sql query to the $conn connection
#$rs contains the result set in the form of an array
$rs = mysql_query($sql,$conn);

?>




</body>
</html>

But I still get this message:

Customer Price Category Results for :

(Then a Horizontal Line)

Then Blank.

MadTechie · August 23, 2007

oh

$rs = mysql_query($sql,$conn);

//add code below
while ($row = mysql_fetch_assoc($rs))
{
    echo $row["Customer Username"];
    echo $row["Booking ID"];
    echo $row["Check In"];
}

adamdyer · August 23, 2007

hmm! i seemed to have mesed up somewher - im gonna start those pages again, if i get any probs I'll repost here

MadTechie · August 23, 2007

change

$rs = mysql_query($sql,$conn);

to

$rs = mysql_query($sql,$conn)or die(mysql_error());

it may reveal the problem

adamdyer · August 23, 2007

ok - i re-did the page and now it look like this

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
<title>View Customers by price category</title>
</head>
<body>

<?php 

#get the Car category i.e. Acat variable
$CAT = $_GET['Acat'];

#--------------------------------------------------------

echo("<font face=Courier size=3>");
echo("<p>Car Results for :$CAT <hr></P>");

#--------------------------------------------------------

?>

<?php

# connect to MySQL
$conn = @mysql_connect("localhost","ajdref","ref2")
or die ("sorry - could not connect to MySQL"); 

# select the specified database
$rs = @mysql_select_db("ajdref", $conn)
or die ("sorry - could not connect to the database");

#create the query - sets $sql to contain the required query
SELECT * FROM Booking Database where price cat = '$CAT'

#execute the query - uses the mysql_query() function to issue the $sql query to the $conn connection
#$rs contains the result set in the form of an array
$rs = mysql_query($sql,$conn)or die(mysql_error());

?>

</body>
</html>

but after re-doing them its gone back to being a complete blank page :-(

MadTechie · August 23, 2007

SELECT * FROM Booking Database where price cat = '$CAT'

should be

$sql = "SELECT * FROM Booking Database where price cat = '$CAT'";

also you need to add this

oh

$rs = mysql_query($sql,$conn);

//add code below
while ($row = mysql_fetch_assoc($rs))
{
    echo $row["Customer Username"];
    echo $row["Booking ID"];
    echo $row["Check In"];
}

adamdyer · August 23, 2007

done - and it changed , we're getting somewhere :-D

now i get this

customerpricecategory3.php for :A

-------------------------------------------------------------------------------

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 'Database where price cat = 'A'' at line 1

MadTechie · August 23, 2007

i should of checked this

$sql = "SELECT * FROM Booking Database where price cat = '$CAT'";

to

$sql = "SELECT * FROM `Booking Database` where `price cat` = '$CAT'";

i assume price cat contains A's & B's ?

adamdyer · August 23, 2007

yeh categories A and B

A- £40

B - £60

Changed what you said, am getting the right results now, just in a 'funny way'

customerpricecategory3.php for :A

--------------------------------------------------------------------------------
