[RESOLVED] Alternating Row Color

[sonicfreelance]

Hello all....

Here is my rss feed display script. How do I change it to have alternating row colors?

<?php
$xmlfile = fopen("http://www.sonicfreelance.com/rss_sonic.php?t=0", "r");
if(!$xmlfile)die("script not functioning");
$readfile = fread($xmlfile ,40000);
$searchfile = eregi("<item>(.*)</item>", $readfile ,$arrayreg);
$filechunks = explode("<item>", $arrayreg[0]);
$count = count($filechunks);
for($i=1 ; $i<=$count-1 ;$i++)
{
ereg("<title>(.*)</title>",$filechunks[$i], $title);
ereg("<link>(.*)</link>",$filechunks[$i], $links);
echo "<li>";
echo "<a href ='$links[1]'>$title[1]</a>";
echo "</li>";
}
?> 

thanks,

Ned

for($i=1 ; $i<=$count-1 ;$i++)
{
  $color = ($i%2==0)?'ffffff':'cccccc';
/**
 *  Place the $color variable wherever you need to
 *  to color the row.  Not sure of the complete output, 
 *  so I don't know where you want it to go.
 */
  ereg("<title>(.*)</title>",$filechunks[$i], $title);
  ereg("<link>(.*)</link>",$filechunks[$i], $links);
  echo "<li>";
  echo "<a href ='$links[1]'>$title[1]</a>";
  echo "</li>";
}

the color would be on this line:

echo "<li>";
echo "<a href ='$links[1]'>$title[1]</a>";
echo "</li>";

but that is the problem....the code only shows 1 line of output....

thanks,

Well, if you are using a table to output the results, you could say
<tr><td background-color:#<?PHP echo $color;?><a href ='$links[1]'>$title[1]</a></td></tr>

or you could use <span style="color:#<?PHP echo $color;?>">
<a href ='$links[1]'>$title[1]</a></span>

Not sure if you can use formatting attributes with <li> but I wouldn't claim to be an expert with html, xhtml etc.

Yes you can apply a style to a <li> element e.g

<li style="color:red" title="A red colored fruit.">Apple</li>
<li style="color:green" title="A green colored fruit.">Pear</li>

you will notice that I also added a title so you get a tooltip if you point at the list item.
Using this you would use Blu's approach and apply it to the opening <li> tag.

Shouldn't this:

echo "<a href ='$links[1]'>$title[1]</a>";

be dependant upon the $i looped variable? Perhaps? maybe?

for($i=1 ; $i<=$count-1 ;$i++) 
{ 
  $color = ($i%2==0)?'ffffff':'cccccc'; 
/** 
*  Place the $color variable wherever you need to 
*  to color the row.  Not sure of the complete output, 
*  so I don't know where you want it to go. 
*/ 
  ereg("<title>(.*)</title>",$filechunks[$i], $title); 
  ereg("<link>(.*)</link>",$filechunks[$i], $links); 
  echo "<li style='background-color: #$color'>"; 
  echo "<a href ='$links[$i]'>$title[$i]</a>"; 
  echo "</li>"; 
}

that worked...thanks everyone!!!!!!

for($i=1 ; $i<=$count-1 ;$i++)
{
$color = ($i%2==0)?'ffffff':'cccccc';
/**
Place the $color variable wherever you need to
to color the row. Not sure of the complete output,
so I don't know where you want it to go.
/
ereg("<title>(.)</title>",$filechunks[$i], $title);
ereg("<link>(.)</link>",$filechunks[$i], $links);
echo "<li style='background-color: #$color'>";
echo "<a href ='$links[$i]'>$title[$i]</a>";
echo "</li>";
}

you guys are awesome

[sonicfreelance]

Actually that did not work!!

after i put the code in:

<?php
$xmlfile = fopen("http://www.sonicfreelance.com/rss_sonic.php?t=0", "r");
if(!$xmlfile)die("script not functioning");
$readfile = fread($xmlfile ,40000);
$searchfile = eregi("<item>(.*)</item>", $readfile ,$arrayreg);
$filechunks = explode("<item>", $arrayreg[0]);
$count = count($filechunks);
for($i=1 ; $i<=$count-1 ;$i++)
{
  $color = ($i%2==0)?'F7F7F7':'000000';
/**
*  Place the $color variable wherever you need to
*  to color the row.  Not sure of the complete output,
*  so I don't know where you want it to go.
*/
  ereg("<title>(.*)</title>",$filechunks[$i], $title);
  ereg("<link>(.*)</link>",$filechunks[$i], $links);
  echo "<li style='background-color: #$color'>";
  echo "<a href ='$links[$i]'>$title[$i]</a>";
  echo "</li>";
} 
?> 

I realized that the colors were showing up fine...BUT...the second link was missing. So basically the 1st line was there with the background color, but the second link had a backgound color just no link.....

I added some more info and every link after the firs does not show up....the background colors do, but no links....??

thanks,
Ned

Sorry, could be my fault... change the $links[$i] and $title[$i] back to $links[1] and $title[1] respectively....

[sonicfreelance]

thanks,
Ned
