Hi all,

 

just to get this out of the way i have now been working on html / css / php / mysql coding for about 3 weeks.

 

So i dont know too much, on to the problem...

 

I am creating a database for asset managment in and out of our shop I have setup the db and it works with no issues.

So I am currently trying to add fluff as i put it.

 

The guys in the shop want the web page to have a table of information on what is in the shop and when they click on the asset number in the table they want it to open a new page where you can edit the database information of that item.

 

I have no clue how to emplement this after reading diffrent ideas for about 4 hours today I am just stuck and confused.

any ideas or tips would be helpfull

 

 

This first block of code is my status page.


<style>

tr
	{font-size:24px;}
button
	{width:120px}

</style>

<body topmargin="50px">

<?php
 session_start(); 

include("../../Connections/db_connection.php");
$table = "shop_inventory";
mysql_select_db("$db_database", $connect);
unset ($db_username, $db_password);

$currenttime = getdate();

$result = mysql_query("SELECT * FROM shop_inventory WHERE In_Shop='1'");
$test = mysql_fetch_array($result);

echo "<table border='1' align='center' style='text-align:center' cellpadding='10' width='100%'>
<tr>
<th>Asset number</th>
<th>Building</th>
<th>Room number</th>
<th>In date</th>
</tr>";

$_SESSION['array_row'] = $test;

while($row = mysql_fetch_array($result))
   {
   $style = '';
   //if ($currenttime - $row['Entered_Shop_Time'] == 0 || 1)
   		$style = 'style="background-color:#00FF00"';
   
	echo "<tr>";
	echo "<td> <button onClick=../subpages/edititems.php>" . $row['Asset'] . "</button> </td>";
	echo "<td>" . $row['Building'] . "</td>";
	echo "<td>" . $row['Room_Number'] . "</td>";
	echo "<td $style>" . date("F j, Y", strtotime($row['Entered_Shop_Time']))  . "</td>";
	echo "</tr>";
   
   }
echo "</table>";

mysql_close($connect);

?>

</body>

 

 

This second block of code is the page where i want to dump the table info into for editing.

 


<?php
session_start(); 

include("../../Connections/db_connection.php");
$table = "shop_inventory";
mysql_select_db("$db_database", $connect);
unset ($db_username, $db_password);
//$Asset = $_POST['Asset'];
$Session = $_SESSION['array_row'];

//$data = mysql_query("SELECT * FROM shop_inventory WHERE Asset=$session");
//$query = mysql_query($data) or die ("Cannot select database." . mysql_error());
//$Session = mysql_fetch_array($data);

?>

    <body>
    	<div style=" padding-top:5px;">
                <h1><center>Add New Items</center></h1>
        </div>
      <form name="myForm" action="afteredititems.php" method="post">
            Asset Number: <input type="text" name="Asset" value="<?php echo $Session['Asset']?>"/><br /><br />
            Manufacture: <input type="text" name="Manufacture" value="<?php echo $Session['Manufacture']?>"/><br /><br />
            Model: <input type="text" name="Model" value="<?php echo $Session['Model']?>"/><br /><br />
            Serial Number: <input type="text" name="Serial_Number" value="<?php echo $Session['Serial_Number']?>"/><br /><br />
            Building: <input type="text" name="Building" value="<?php echo $Session['Building']?>"/><br /><br />
            Room Number: <input type="text" name="Room_Number" value="<?php echo $Session['Room_Number']?>"/><br /><br />
            <input type="hidden" name="In_Shop" value="1"/>
            Type of Equipment: <select name="Type" value="<?php echo $Session['Type']?>">
                                <option value="desktop">Desktop</option>
                                <option value="laptop">Laptop</option>
                                <option value="ipad">Ipad</option>
                                <option value="ipod">Ipod</option>
                                <option value="projector">Projector</option>

            <center><input type="submit" value="Add Item"/></center>
        </form>
    </body>
</html>

 

 

And lastly I have a page that redisplays the edited information.

 


<?php

//$Asset = $_POST['Asset'];

//$data = mysql_query("SELECT * FROM shop_inventory WHERE Asset=$Asset");
//$query = mysql_query($data) or die ("Cannot select database." . mysql_error());
//$data2 = mysql_fetch_array($data);


include("../../Connections/db_connection.php");
$table = "shop_inventory";
mysql_select_db("$db_database", $connect);
unset ($db_username, $db_password);
$Asset = $_POST['Asset'];
$Manufacture = $_POST['Manufacture'];
$Model = $_POST['Model'];
$Sn = $_POST['Serial_Number'];  //<---- possibly fubar check sn everywhere
$Building = $_POST['Building'];
$Room_Number = $_POST['Room_Number'];
$Type = $_POST['Type'];

$data = mysql_query("UPDATE `shop_inventory` SET  Manufacture='$Manufacture', Model='$Model', Serial_Number='$Sn', Building='$Building', Room_Number='$Room_Number', Type='$Type' WHERE Asset=$Asset");
//$query = mysql_query($data) or die("could not execute query.". mysql_error());

?>

<body>

<!-- display changes -->

Room Number: <?php echo $Room_Number ?><br />

</body>
</html>

 

 

I know there is a lot of poorly formated code and more then likely it is hard to read as I was going to do cleanup after I had all my features working.

 

After doing all the digging i found out about sessions and how they are used to pass data, I thought it would be a good method but I just could not figure out how to send information from the table if the table is reciving its info from an array.

 

any help would be appreciated thanks.

If you've learned this much in three weeks I'd say you're doing really well, keep up the good work!!!

 

I'm not a good programmer or anything but I know a little and the first thing I would say is learn use mysqli instead of mysql, you can read more about it here. http://www.php.net/manual/en/book.mysqli.php

I wrote a nice long reply but I got distracted so the page timed out and I lost everything I wrote :(

 

Anyways, you want to pass the data in the URL and then retrieve it on the next page using the GET method

 

Status Page

 

Instead of this

echo "<td> <button onClick=../subpages/edititems.php>" . $row['Asset'] . "</button> </td>";

 

use this, I'm using a link instead of a button but you can change it to meet your needs

<a href=\"edititems.php?Asset=$row[Asset]\" target=\"_blank\">Edit</a>

 

Edit Items page

//this is the data you got from status page
$Asset = mysqli_real_escape_string($con, trim($_GET['Asset']));

$query = "SELECT * from shop_inventory WHERE Asset = '$Asset'";

$result = mysqli_query($con, $query) or die(mysqli_error($con));

if($result)
{
   $row = mysqli_fetch_array($result, MYSQLI_ASSOC);
   echo"
   <form name=\"myForm\" action=\"afteredititems.php\" method=\"post\">
   Asset Number: <input type=\"tex\t" name=\"Asset\" value=\"$row[Asset]" />
   ";
}

Here's a revision of the above code for the edit items page, this code lets you know if the update was successful, this will show you how to use one page to display, edit, and then update the data in one page :)

 

<?php
include("../../Connections/db_connection.php");

// if update button has been pressed, this updates the db
if(isset($_POST['update']))
{
// assign vars
$Asset = mysqli_real_escape_string($con, trim($_POST['Asset']));
$Manufacture = mysqli_real_escape_string($con, trim($_POST['Manufacture']));

$query = "UPDATE shop_inventory SET Manufacture='$Manufacture', ect... WHERE Asset = '$Asset'";

$result = mysqli_query($con, $query) or die(mysqli_error($con));

if($result)
{ 
?>

	<script language = "javascript">
	alert('Update Successful');
	</script>	

<?php
}
else
{
?>
	<script language = "javascript">
	alert('Update Failed');
	</script>	

<?php
}
}

//this is the data you got from status page
$Asset = mysqli_real_escape_string($con, trim($_GET['Asset']));

$query = "SELECT * from shop_inventory WHERE Asset = '$Asset'";

$result = mysqli_query($con, $query) or die(mysqli_error($con));

if($result)
{
   $row = mysqli_fetch_array($result, MYSQLI_ASSOC);
   echo"
   <!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>
<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />
<title>Add Items</title>
</head>
   <body>
   <form name=\"myForm\" action=\"$_SERVER[php_SELF]\" method=\"post\">
   Asset Number: $row[Asset]<br />
   Manufacture: <input type=\"text\" name=\"Manufacture\" value=\"$row[Manufacture]" /><br />
   <input type=\"hidden\" name=\"Asset\" value=\"$row[Asset]" />
   <input type=\"submit\" name=\"update\" value=\"Update\">
   </form>
   </body>
   </html>
   ";
}
?>

Here's another version to play with.  Not about to redo whole thing but inserts new records and updates records.

 

<?php

mysql_select_db("$db_database", $connect);


$date=date('Y-m-d');
$currenttime = getdate();
if (isset($_GET['edit']) && ctype_digit($_GET['edit'])){
$_SESSION['item_number']=$_GET['edit'];
header("location: samplepage.php");
exit;
}
if (isset($_POST['cancel'])){	
unset($_SESSION['item_number']);	
header("location: samplepage.php");
exit;

} 
if (isset($_POST['additem'])){	
$Manufacture = mysql_real_escape_string(trim($_POST['Manufacture']));
$Model = mysql_real_escape_string(trim($_POST['Model']));
  //<---- possibly fubar check sn everywhere
$Sn = mysql_real_escape_string(trim($_POST['Serial_Number']));
$Building = mysql_real_escape_string(trim($_POST['Building']));
$Room_Number = mysql_real_escape_string(trim($_POST['Room_Number']));
$Type = mysql_real_escape_string(trim($_POST['Type']));

$data ="INSERT INTO `shop_inventory` (Manufacture,Model,Serial_Number,Building,Room_Number,Type,Entered_Shop_Time) VALUES('$Manufacture', '$Model','$Sn','$Building','$Room_Number','$Type','$date')";
$query = mysql_query($data) or die("could not execute query.". mysql_error());
}
if (isset($_POST['updateitem'])){	
$Asset = mysql_real_escape_string($_SESSION['item_number']);
$Manufacture = mysql_real_escape_string(trim($_POST['Manufacture']));
$Model = mysql_real_escape_string(trim($_POST['Model']));	
  //<---- possibly fubar check sn everywhere
$Sn = mysql_real_escape_string(trim($_POST['Serial_Number']));
$Building = mysql_real_escape_string(trim($_POST['Building']));
$Room_Number = mysql_real_escape_string(trim($_POST['Room_Number']));
$Type = mysql_real_escape_string(trim($_POST['Type']));

$data ="UPDATE `shop_inventory` SET  Manufacture='$Manufacture', Model='$Model', Serial_Number='$Sn', Building='$Building', Room_Number='$Room_Number', Type='$Type' WHERE Asset=$Asset";
$query = mysql_query($data) or die("could not execute query.". mysql_error());

WOW,

 

Thank you guys this is some great stuff, I have adapted some of the code to my site and it works really well.

 

I will definitely take a look at mysqli and see what the difference is.

 

After this I am defiantly staying on this site for any further help on this project, and to offer any help i can to other noobs.

 

Again thanks a lot guys.
