[SOLVED] background alternating colour code problem

d3vilr3d · October 8, 2007

Hi,

Im having problem making my background alternate between colors. Following is my code, the result alternates 2 colors ok, but prints each entry from my database 30 times. Please help me fix, thanks soo much.

		$color1 = "#CCFFCC"; 
		$color2 = "#BFD8BC"; 
		$row_count = 0; 
		$sql_events = mysql_query("SELECT * FROM ad ORDER BY id ASC") or die (mysql_error()); 
		if (!preg_match("/[a-z]/i",$price)&&!preg_match("/\\$/",$price)) $price = "$".$price;
		while ($row = mysql_fetch_array($sql_events)) {
		$row_color = ($row_count % 2) ? $color1 : $color2; 
		echo "<TR bgcolor='$row_color'>\n";
		$row_count++; 
		echo "<TD><A href='$ad_url'>".$ads[$i][title]."</A>";
			if (strlen($ads[$i][city])<1) {
			echo "";
			}else{
			echo "(".$ads[$i][city].")";}
			if (strlen($ads[$i][price])<1) {
			echo "";
			}else{
			echo "<SPAN class='adlist_price'>".substr($price,0,10)."</SPAN> ";}
		if (intval($ads[$i][num_pics])>0) echo "<IMG src='images/picture.gif' border='0' style='vertical-align:middle'>";	
		echo "<br>";
		echo "$content";
		echo "</TD>";
		echo "</TR>";
					}
	}

I use this approach:

$color1=somecolor

$color2=someothercolor

$c=1;

while...{

if($c==1){

$cssvar=$color1;

$c=2;

//use the $cssvar

}

elseif($c==2){

$cssvar=$color2;

$c=1;

//use the $cssvar

}

Is that code inside a loop which executes 30 times?

What is in $content?

I think the code below is a little more eficcient in selecting the row color. However, the problem you describe is not due to that. In fact, I am a littel confused by your code alltogether. You have a while loop which sets $row to a record from the result set. But nowhere int he while loop do you use that data! Instead you are using an array $ads which isn't set anywhere in that code. I think that is the root of your problem

<?php

//$color1 = "#CCFFCC"; 
//$color2 = "#BFD8BC"; 
//$row_count = 0; 
$sql_events = mysql_query("SELECT * FROM ad ORDER BY id ASC") or die (mysql_error()); 
if (!preg_match("/[a-z]/i",$price)&&!preg_match("/\\$/",$price)) $price = "$".$price;
while ($row = mysql_fetch_array($sql_events)) {
   $row_color = ($row_color!='#CCFFCC') ? '#CCFFCC' : '#BFD8BC'; 
   echo "<TR bgcolor='$row_color'>\n";
   //$row_count++; 
   echo "<TD><A href='$ad_url'>".$ads[$i][title]."</A>";
   if (strlen($ads[$i][city])<1) {
       echo "";
   }else{
       echo "(".$ads[$i][city].")";}
       if (strlen($ads[$i][price])<1) {
           echo "";
       }else{
           echo "<SPAN class='adlist_price'>".substr($price,0,10)."</SPAN> ";
       }
       if (intval($ads[$i][num_pics])>0) {
           echo "<IMG src='images/picture.gif' border='0' style='vertical-align:middle'>";
       }
       echo "<br>";
       echo "$content";
       echo "</TD>";
       echo "</TR>";
   }
}

?>

well, im fixing the php file from the previous programmer. Here is the whole file:

<?PHP
if (!defined("MC_KEY")) die("Security Error.");

include_once('includes/database.php');
require_once('config.php');

if ($_REQUEST[action]=="showads") {
?>
<DIV id="ads_search_form">
	<?PHP include('search_form.php'); ?>
</DIV>
<DIV id="ads_list">
<?PHP
	$sql = "";
	if (isset($_REQUEST[regionid]) && isset($_REQUEST[subcategoryid])) {
		$url_params = "regionid=".intval($_REQUEST[regionid])."&subcategoryid=".intval($_REQUEST[subcategoryid]);
	} else {
		// SCRIPT TO BAIL OUT!!!
		//echo "<SCRIPT></SCRIPT>";
	}
	$ads = $info->getAds($_REQUEST[regionid],$_REQUEST[subcategoryid]);
?>
<TABLE id="ad_table">
<?PHP
	$cur_date = "";
	for ($i = 0; $i < sizeof($ads); $i++) {
		$ad_url = "?action=display&adid=".$ads[$i][id]."&$url_params";
		if ($cur_date!=date("D M d",$ads[$i][epoch_date])) {
			$cur_date = date("D M d",$ads[$i][epoch_date]);
			echo "<TR><TD colspan='3'> </TD></TR>";
			/*echo "<TR class='ad_date_separator'><TD colspan='3'>".date("D M d",$ads[$i][epoch_date])."</TD></TR>";*/
		}
		$price = $ads[$i][price];
		$content = $ads[$i][content];
		if (!preg_match("/[a-z]/i",$price)&&!preg_match("/\\$/",$price)) $price = "$".$price;
		echo "<TR>\n";
		echo "<TD><A href='$ad_url'>".$ads[$i][title]."</A>";
			if (strlen($ads[$i][city])<1) {
			echo "";
			}else{
			echo "(".$ads[$i][city].")";}
			if (strlen($ads[$i][price])<1) {
			echo "";
			}else{
			echo "<SPAN class='adlist_price'>".substr($price,0,10)."</SPAN> ";}
		if (intval($ads[$i][num_pics])>0) echo "<IMG src='images/picture.gif' border='0' style='vertical-align:middle'>";	
		echo "<br>";
		echo "$content";
		echo "</TD>";
		echo "</TR>";
	}
?>

</TABLE>
</DIV>
<?PHP
}
?>

Please help me insert the alternating color code. The code i posted earlier, either it doesnt return the 2nd color, or it loops 30 times. So confused.

thanks~

There are a lot of bad standards in that code. Try this:

<?php
if (!defined("MC_KEY")) die("Security Error.");

include_once('includes/database.php');
require_once('config.php');

if ($_REQUEST[action]=="showads") {
    echo "<div id=\"ads_search_form\">\n";
    include('search_form.php');
    echo "</div>\n";
    echo "<div id=\"ads_list\">\n";

    if (isset($_REQUEST[regionid]) && isset($_REQUEST[subcategoryid])) {
        $url_params = "regionid=".intval($_REQUEST[regionid])."&subcategoryid=".intval($_REQUEST[subcategoryid]);
    } else {
        // SCRIPT TO BAIL OUT!!!
        //echo "<script></script>";
    }

    $ads = $info->getAds($_REQUEST[regionid],$_REQUEST[subcategoryid]);

    echo "<table id=\"ad_table\">\n";

    $cur_date = "";

    foreach ($ads as $adRecord) {
        $ad_url = "?action=display&adid=".$adRecord[id]."&$url_params";
        if ($cur_date!=date("D M d",$adRecord[epoch_date])) {
            $cur_date = date("D M d",$adRecord[epoch_date]);
            echo "<tr><td colspan='3'> </td></tr>";
            /*echo "<tr class='ad_date_separator'><td colspan='3'>".date("D M d",$adRecord[epoch_date])."</td></tr>";*/
        }

        $price = $adRecord[price];
        if (!preg_match("/[a-z]/i",$price)&&!preg_match("/\\$/",$price)) { $price = "$".$price; }

        $row_color = ($row_color!='#ccffcc') ? '#ccffcc' : '#bfd8bc';

        echo "<tr style=\"background-color:$row_color;\">\n";
        echo "  <td>\n";
        echo "    <a href='$ad_url'>".$adRecord[title]."</a>\n";
        if (strlen($adRecord[city])) {
            echo "    (".$adRecord[city].")\n";
        }
        if (strlen($adRecord[price])) {
            echo "    <span class='adlist_price'>".substr($price,0,10)."</span>\n";
        }
        if (intval($adRecord[num_pics])) {
            echo "    <img src='images/picture.gif' border='0' style='vertical-align:middle'>\n";
        }

        echo "    <br>$adRecord[content]\n";
        echo "  </td>";
        echo "</tr>";
    }
    echo "</table>\n";
    echo "</div>\n";
}

?>

wow, works like a charm.

thanks so much!

I am studying your coding

Psycho · October 9, 2007

Don't forget to make the thread as solved. But post back any questins if you have them.

Although I made a lot of changes for consistency and standards adhereance, this was all you needed to add to the original code:

$row_color = ($row_color!='#ccffcc') ? '#ccffcc' : '#bfd8bc';
echo "<tr style=\"background-color:$row_color;\">\n";
