table row colour

witham · February 21, 2008

I am hoping someone can point me in the right direction, I have a php script that adds a row to an sql database but I would like to change the background colour of the added row:

<?

//check the $ProdName variable to see if it has data if not send the user back to the entry page
// this has to be done before any output

$ProdName = $_GET['ProdName'];
$ProdEquiv = $_GET['ProdEquiv'];
$Manufacturer = $_GET['Manufacturer'];
$ProdNar = $_GET['ProdNar'];
$Category = $_GET['Category'];


if (empty($ProdName)){  
header("Location: addprod.php"); 
die ("opps");  
}

if (empty($ProdEquiv)){  
header("Location: addprod.php"); 
die ("opps");  
}


$dbuser  = 'user';		// your database server user name
$dbhost  = 'localhost';		// name of the sql server
$dbpass  = '';		// your database server password
$dbname  = 'ace;		// the name of the database to connect to 

// use a compare statement to check for duplicates

$sqlCOMPARE	= "SELECT * from prodname where '$ProdName' = proddesc;";


// the sql query to insert data into the prodname table


$sqlINSERT	= "INSERT into prodname values
	  (null, '$Manufacturer', '$Category', '$ProdName', '$ProdNar', '$ProdEquiv');";

$sqlINSERT	= strtoupper($sqlINSERT);


//use to display the desired data $sqlSELECT

$sqlSELECT	= "SELECT MANNAME, prodtype, proddesc, prodnar, prodequiv 
	FROM man, produse, prodname where manno = manid
	and manid = '$Manufacturer'
	and useid = '$Category' 		   
	and prodid = useid
                		and manno = MANID
	and useid = USEID
	order by MANNAME;";

// mysql_connect connects to the database server and returns a link to the the resource
$dblink = @mysql_connect("$dbhost","$dbuser","$dbpass") 
or die("<p><b>Could not connect to database server: ($dbhost)</b></p>\n");

// mysql_select_db selects a database to use on the database server pointers to by $dblink
// the @ sign before the command supresses any error messages
@mysql_select_db ($dbname , $dblink)
or die ("<p><b>Could not connect to database ($dbname)</b></p>\n");


// now execute the next query to determine if a duplicate has been entered and use
// an if statement to return the user to the entry page if this is true


$result  = mysql_query($sqlCOMPARE, $dblink)
or die("<p>Error Processing Query</p><hr /><p>".mysql_error()."</p>\n");


if (  mysql_num_rows($result) > 0  ){  
header("Location: alreadyin.php");  
die ("opps");  

}

// now execute the next query to update the database table


$result  = mysql_query($sqlINSERT, $dblink)
or die("<p>Error Processing Query</p><hr /><p>".mysql_error()."</p>\n");



// now execute the next query to display these results

$result  = mysql_query($sqlSELECT, $dblink)
or die("<p>Error Processing Query</p><hr /><p>".mysql_error()."</p>\n");

?>



<style type="text/css">
tr {color: white; font-family: arial; font-weight: bold;}
body {

background-image: url();

<head>

<!-- set the css format for the page-->


<body>

<?

// output the table and the first row headings

echo'<table align = "center" border=0>' . "\n";
echo'<tr><td colspan = 3 align = "center"><table width="100" border="0" cellspacing="10" cellpadding="10">
  <tr>
    <th scope="row"><img src="car.jpg" width="150" height="150"></th>
    <td><img src="gears.jpg" width="150" height="150"></td>

    </tr>
</table></td></tr>';



echo '<table align = "center" border="1" cellspacing="2" cellpadding="2">' . "\n";
echo "<tr bgcolor = #000000><td>MANUFACTURER</td><td>PRODUCT TYPE</td><td>PRODUCT NAME</td><td>PRODUCT DESCRIPTION</td><td>PRODUCT EQUIVALENT</td></tr>\n";


// mysql_fetch_array fetches the results from the query a row at a time each time it's called
// the result is returned as an array that can be referenced either by field name or by it's index


while ($row = mysql_fetch_array ($result)) 


// loop through the rows outputing them as html table rows

   {



// $row["fieldname"] returns the content for the field in the current row


echo "<tr><td>" . $row["MANNAME"]. 	"</td>";
   	echo "<td>" 	. $row["prodtype"]. 	"</td>";
   	echo "<td>" 	. $row["proddesc"]. 	"</td>";
echo "<td>"	. $row["prodnar"].	"</td>";
   	echo "<td>QUALUBE " 	. $row["prodequiv"]. 	"</td></tr>";


   }


// close html table tag
echo "</table>\n";

// the mysql_free_result command removes any resources relating to the query results
// this happens automatically at the end of the script but still better to free up now
mysql_free_result ($result);

// the mysql_close command severs the link to the database, with scripts that make multiple
// queries on the same database the command only needs to be done once after all queries are completed
@mysql_close ($dblink)     
or die( "<p><b>Error while closing connection to database server:" . 
        "($dbhost)</b></p>");

?>

It is a while since my php college course and I would really appreciate some help

Thanks

You only have to edit the HTML to change the background colour, as you don't want/need to edit the database entry.


echo "<tr><td>" . $row["MANNAME"]. 	"</td>";
   	echo "<td>" 	. $row["prodtype"]. 	"</td>";
   	echo "<td>" 	. $row["proddesc"]. 	"</td>";
echo "<td>"	. $row["prodnar"].	"</td>";
   	echo "<td>QUALUBE " 	. $row["prodequiv"]. 	"</td></tr>";

I assume it's there you're wanting to change the background colour, so you could change it to this:


echo "<tr><td style=\"background-color: #C0C0C0\">" . $row["MANNAME"]. 	"</td>";
   	echo "<td style=\"background-color: #C0C0C0\">" 	. $row["prodtype"]. 	"</td>";
   	echo "<td style=\"background-color: #C0C0C0\">" 	. $row["proddesc"]. 	"</td>";
echo "<td style=\"background-color: #C0C0C0\">"	. $row["prodnar"].	"</td>";
   	echo "<td>QUALUBE " 	. $row["prodequiv"]. 	"</td></tr>";

Thanks very much for your post but won't this change the background of the whole table?

I only want to change the colour of the added row

Bauer418 · February 22, 2008

You can add

style="background-color: #eeeeee"

To the tr or td tags to change the color of a single row, as posted above.

Create a boolean variable before the loop, and in the while loop NOT it so it flips on every iteration. Use that true/false value to change the content of a variable, say $colour, and then use that in the TR tag to set the background colour (using CSS). Here's a quick example.

<?php
$rowState=false;
while ($row = mysql_fetch_array ($result))
// loop through the rows outputing them as html table rows
   {
$colour=($rowState=!$rowState) ? "#FF0000" : "#00FF00";
// $row["fieldname"] returns the content for the field in the current row
echo "<tr style=\"background-color: $colour;\"><td>" . $row["MANNAME"]. 	"</td>";
   	echo "<td>" 	. $row["prodtype"]. 	"</td>";
   	echo "<td>" 	. $row["proddesc"]. 	"</td>";
echo "<td>"	. $row["prodnar"].	"</td>";
   	echo "<td>QUALUBE " 	. $row["prodequiv"]. 	"</td></tr>";
   }
?>

I'd suggest using CSS classes instead of changing the background-color directly, just for ease of changing it later.

Thanks everyone for your help and examples, one question could I use mysql_affected_rows to identify the added row and change the background colour?

Bauer418 · February 23, 2008

mysql_affected_row will tell you how many rows were updated, not which ones. Although, if you were the one editing the rows, shouldn't you be able to tell which ones you changed?
