Hello,
I am fairly new to PHP but ancient with HTML. I have created a page that my client uses to update their gigs on a display page. After the gig, which is a charity event, they want to update the MySQL record that hols the details of the gig with the amount of donations they received. I have amended the code to include an update query but no matter what I try it will not update the MySQL table. It may be a very silly mistake that I as a noobie cannot see. Could anyone help please? The code is below:
<!DOCTYPE HTML>
<?php
Include('Includes/sig_connect.php');
IF(isset($_POST['form_sub']))
{
$query = 'INSERT INTO gigs (
DATE, VENUE, DETAILS)
VALUES (
"'.$_POST['DATE'].'",
"'.$_POST['VENUE'].'",
"'.$_POST['DETAILS'].'"
)';
if(!mysql_query($query, $db_link))
{
Echo 'Query failed to run'.mysql_error();
exit;
}
# header('Location: '.$_SERVER['PHP_SELF']);
# exit;
} #End if isset form sub
?>
<html>
<head>
<title> Upcoming Appearances </title>
<br>
<BR>
<link rel="stylesheet" type="text/css" href="wightsupp.css">
<script src="jquery.js">
</script>
<div id="content"></div> </div>
</head>
<BODY background="clouds3.jpg">
<script type="text/javascript">
$(document).ready(function(){
$("tr:nth-child(even)").addClass("red");
$("tr:nth-child(odd)").addClass("yellow");
});
</script>
<?PHP
# Delete Record Here
if(isset($_GET['delete_id']))
{
$query = 'DELETE FROM gigs WHERE ID = "'.$_GET['delete_id'].'"';
if(!mysql_query($query, $db_link))
{
Echo 'Query failed to run'.mysql_error();
exit;
}
} #End if isset delete
# THIS IS THE PROBLEM AREA! IT JUST WON'T UPDATE THE TABLE
IF(isset($_POST['update']))
{
$query = 'update gigs SET donations = ("'.$_GET[DONATIONS].'") WHERE ID = "'.$_GET[update_id].'"';
if(!mysql_query($query, $db_link))
{
Echo 'Query failed to run'.mysql_error();
exit;
}
} #End if isset delete
# header('Location: '.$_SERVER['PHP_SELF']);
# exit;
#Add a record Here
IF(isset($_GET['add']))
{
$query = "SELECT * FROM gigs";
$result = mysql_query($query, $db_link);
$row = mysql_fetch_assoc($result);
?>

Re: Problem with UPDATE query
Your HTML form is using Post, but in your MySQL Update statement, you're using $_GET.
Should this use $_POST, like your Insert statement does?
