updating multiple sql records using checkboxes

jacko_162 · December 21, 2010

I know how to pull data from sql table and limit down the results,

what i wanted to do is pull data from a sql table 'finished' and list data that has paid='0'

this is then limited to show the amount of rows set by variable 'maxPay'

here is my list what im pulling atm;

    <h2>Payment </h2>
    <?php 
if($userType[user_type]==28){	
$queryPay = mysql_query("SELECT * FROM finished WHERE paid='0'&&method!='FALSE'&&method!='credit';") or die(mysql_error());

$queryAdmin = mysql_query("SELECT maxPay FROM `admin`;") or die(mysql_error());

$row = mysql_num_rows($queryPay);
//echo $row."row<br />";
$rowsArray = mysql_fetch_assoc($queryAdmin);
$rows = $rowsArray[maxPay];
//echo $rows."rows<br />";

if($rows>$row){
	$r=$row;
}
else{
	$r=$rows;
}
$s=0;
while($s<$r){
	if($_POST[complete]==TRUE){
		mysql_query("UPDATE `finished` SET `paid`='$_POST[paid]' WHERE `auctionID`='$_POST[aid]';");
		$_POST[complete] = FALSE;

	}
	$s++;
}

$t=0;
while($t<$r){
	$queryuser = mysql_query("SELECT * FROM finished WHERE paid='0'&&method!='FALSE'&&method!='credit';") or die(mysql_error());

	$user = mysql_result($queryuser, $t, "username");
	//echo $user;
	$item = mysql_result($queryuser, $t, "itemName");
	//echo $item;
	$value = mysql_result($queryuser, $t, "marketPrice");
	//echo $value;
	$method = mysql_result($queryuser, $t, "method");
	//echo $method;
	$id = mysql_result($queryuser, $t, "auctionID");
	//echo $id;



	//echo $method;
	if($method=='isk'){
		?>
		<FORM method="post" action="pay.php">
		<input type="hidden" name=complete value="TRUE" />
		<input type="hidden" name=paid value="YES" />
		<input type="hidden" name=username value="<? echo $user; ?>" />
		<input type="hidden" name=aid value="<? echo $id; ?>" />
		<input type="submit" value="Paid" /><?
		echo $user." won a ".$item." he selected to receive ".$value."ISK.";

		echo "<br />";
		?></FORM><?
	}
	elseif($method=='ship'){
		?>
		<FORM method="post" action="pay.php">
		<input type="hidden" name=complete value="TRUE" />
		<input type="hidden" name=paid value="YES" />
		<input type="hidden" name=username value="<? echo $user; ?>" />
		<input type="hidden" name=aid value="<? echo $id; ?>" />
		<input type="submit" value="Paid" /><?
		echo $user." won a ".$item." he selected to receive the ship.";

		echo "<br />";
		?></FORM><?
	}
	else{

	}
	$t++;
}

}
else{
echo "You are not an Admin.";	
}
?>

and pay.php:

<?php 

header('Location: /admin.php');

include "connect.php";
echo $_POST[aid];
if($_POST[complete]==TRUE){
	$tempID = (($_POST[aid])+1);
	mysql_query("UPDATE `finished` SET `paid`='$_POST[paid]' WHERE `auctionID`='$tempID';") or die(mysql_error());
	$_POST[complete] = FALSE;
}
?>

at the moment i am listing all my data, and processing it using pay.php, each dataset has a "paid" button, i want to change this to using a checkbox at end of each data row, and a submit button at the bottom. this way i can select which rows to update and tick the checkbox, then click submit and those rows will then be updated the value '0' in db to a value of 'YES'.

hope i explained myself clearly enough for some help.

im a relative php noob still in training.

managed to find some code snippets which should do the trick

<?php

include "connect.php";

if(isset($_POST['checkbox'])){$checkbox = $_POST['checkbox'];
if(isset($_POST['activate'])?$activate = $_POST["activate"]:$deactivate = $_POST["deactivate"])
$id = "('" . implode( "','", $checkbox ) . "');" ;
$sql="UPDATE finished SET paid = '".(isset($activate)?'YES':'0')."' WHERE auctionID='$auctionID'" ;
$result = mysql_query($sql) or die(mysql_error());
}

$sql="SELECT * FROM finished WHERE paid ='0' AND method='ship'";
$result=mysql_query($sql);

$count=mysql_num_rows($result);
?>

problem now is its not updating the database correctly.?

here is my connect.php script, anything wrong here?

<?php

$dbServer = "db server";
$dbUsername = "username";
$dbPassword = "password";

$db = mysql_connect($dbServer, $dbUsername, $dbPassword) or die("Could not connect.");

if(!$db) 

die("no db");

if(!mysql_select_db("databasename",$db))

	die("No database selected.");

//echo "connected";

?>
