adding cations to images

[Gazz1982]

I have this code which makes a 2 column table with images from a folder, it gets the captions from a text file - see below

 

 

<?php 

$images = "uploads/"; # Location of small versions
$big    = "thumbs/"; # Location of big versions (assumed to be a subdir of above)
$cols   = 2; # Number of columns to display
$text   = "des.txt";

$fh=fopen($text, "r");

while(!feof($fh))
{
  $temp = explode(",", $line);
  $description[$temp[0]] = $temp[1];
  $line=fgets($fh);
  unset($temp);
}

if ($handle = opendir($images)) {
   while (false !== ($file = readdir($handle))) {
       if ($file != "." && $file != ".." && $file != rtrim($big,"/")) {
           $files[] = $file;
       }
   }
   closedir($handle);
}

$colCtr = 0;

echo '<table width="100%" cellspacing="3"><tr>';

foreach($files as $file)
{
  if($colCtr %$cols == 0)
    echo '</tr><tr><td colspan="' . $cols . '"><hr /></td></tr><tr>';
  $allfiles .= $file . ',<br />';
  echo '<td align="center"><a href="' . $images . $big . $file . '"><img width="300px" src="' . $images . $file . '" /></a><br />' . $description[$file][0] . '</td>';
  $colCtr++;
}

echo '</table>' . "\r\n";
echo $allfiles;

?> 

 

this file des.txt has      file_name,caption      however when implemented it only seems to display the 1st letter of the caption - any ideas why and how to solve? Thanks

in this piece of your code I don't understand what is getting exploded. $line doesn't get defined until after explode(). Please explain

 

while(!feof($fh))

{

  $temp = explode(",", $line);

  $description[$temp[0]] = $temp[1];

  $line=fgets($fh);

  unset($temp);

}

OK NOW SET AS:

 

while(!feof($fh))
{
  $line=fgets($fh);  
  $temp = explode(",", $line);
  $description[$temp[0]] = $temp[1];
  unset($temp);
}

ok great. now we have the $description array I don't know how you want to iterate through it but if its consecutive we can just grab the first key and then move the pointer to the second and so on

 

foreach($files as $file)

{

  if($colCtr %$cols == 0)

  $descript = current($description);

    echo '</tr><tr><td colspan="' . $cols . '"><hr /></td></tr><tr>';

  $allfiles .= $file . ',<br />';

  echo '<td align="center"><a href="' . $images . $big . $file . '"><img width="300px" src="' . $images . $file . '" /></a><br />' . $descript . '</td>';

  $colCtr++;

next($description);

}
