my php code

PHP Code:


			
<?php
$fp = fopen('data.txt','r');
if (!$fp) {echo 'ERROR: Unable to open file.'; exit;}
 
while (!feof($fp)) {
$line = fgets($fp, 1024); //use 2048 if very long lines
list ($field1, $field2, $field3) = split ('\|', $line);
echo '
<div><a href="'.$field1.'">'.$field2.'<br><img src="'.$field3.'"></a></div>';
$fp++;
}
 
fclose($fp);
 
?>

my text database code per line

Code:

URL|NAME|IMAGE

how can i get the data (more that 1 line) to show up side by side for a set number before starting a new one. (all images will be the same size, and at the moment it shows the information line after line.
(I have not used tables but i think that the tables will be the only way to go for what I want.)

Tables aren't necessary, but they're commonly used. You just need to modify your loop. For example, if you want it to show three links/images per line:

PHP Code:


			
$i = 0;
while(!feof($fp)) {   
   $i++;
   /* Do your stuff */
   if(($i % 3)==0)
   {
      // End your table row here.
   }
}

There are a couple small things this doesn't take into account, but you get the idea

done

new problem,

how do i get it to only show certain stuff based on whats in $field3.

for example if in $field3 there is the text butterflye then It only shows those on that page. (On different pages I want to set it to show other pets)

also this code isnt working (page doesnt load)

Quote:

<?php
$fp = fopen('data.txt','r');
if (!$fp) {echo 'ERROR: Unable to open file.'; exit;}

while (!feof($fp)) {
$line = fgets($fp, 1024); //use 2048 if very long lines
list ($field1, $field2, $field3) = split ('\|', $line);

$i = 0;
while(!feof($fp)) {
$i++;
echo '<td class="td"><div align="center"><a href="'.$field1.'">'.$field2.'<br><img src="pets/'.$field3.'.png" width="110"></a></div></td>';
if(($i % 3)==0)
{
echo "</tr>";
echo "<tr>";
}
}

$fp++;
}

fclose($fp);
?>

Stop incrementing $fp

**addonchat** · 05-07-2008, 08:28 PM

Oh -- and from your code it looks like there is only one set of data per line, so you can call fgets without the second parameter.

**simster** · 05-07-2008, 08:29 PM

i have removed

$fp++;
}

and it still doesnt work.

**addonchat** · 05-07-2008, 08:31 PM

What does your web server error log say? Any warnings generated? If you view the source do you just see empty table data? Throw in some print() commands to see where it's stopping.

**simster** · 05-07-2008, 08:31 PM

there is nothing in the pages source at all.

**VirtuosiMedia** · 05-07-2008, 08:52 PM

Are you including your html page into your php page?

**simster** · 05-07-2008, 08:57 PM

its one page.

a php page with html and css.

**Plugin-Developer** · 05-08-2008, 01:44 AM

simster - could you post a sample data file?

**simster** · 05-08-2008, 01:48 AM

I fixed this (had to rewrite code 2 times after the code I put up here)

That should solve your problem if I'm understanding it correctly. Let me know.

**simster** · 05-08-2008, 02:03 AM
