[RESOLVED] Using pre-selected template to generate html output.

curb

I'm having a hard time explaining this. When I select an image html page, the script scans for %% identifiers and creates the appropriate thumbnail size with an html gallery page for it. The problem is the html gallery. I'm trying to use the image html page as the output, not a default template from $str.

image html page

<table>
<tr>
<td>%image.200.200%</td>
<td>%image.100100%</td>
</tr>
<tr>
<td>%image.300.200%</td>
</tr>
</table>

$str="";
$gallery_path='galleries/';
$template_path='/image_template/';
$folder="students";
$template=$_POST['template'];
$dir=stripslashes($full_dir_path).$gallery_path.$folder."/";
$filename=stripslashes($full_dir_path).$template_path.$template;
$handle = fopen($filename, "a+");
$contents = fread($handle, filesize($filename));
$pageexplode=explode("%image.",$contents);
$i=0;
$width=array();
$height=array();
$num=0;
//setting height and width for the images to be cropped as per the choosen templtate
//for each strts
foreach($pageexplode as $a)
{
 $d=explode("%", $a);

 foreach($d as $e);
 {

$x=explode(".", $d[0]);
if(isset($x[1]))
{
//	echo $x[0] .  $x[1] . "<br>";
	$width[]=$x[0];
	$height[]=$x[1];
	}
}
} //foreach ends
//checcking image in posted folder
$img=array();
 if ($dh = opendir($dir)) {
        while (($file_name=readdir($dh)) !== false) {
      if ((substr($file_name, strlen($file_name) - 4) == '.jpg') && (substr($file_name,0,3)!='tn_')) 
	  { 
  	 $img[]=$file_name;
	  }
	 }
	}
$l=count($width);
$new_files=array();
$images="";
for($i=0;$i<$l;$i++)
{
if(isset($img[$i]))
{
$file=$img[$i];
list($old_width, $old_height) = getimagesize($dir.$file);
$new_width=$width[$i];
$new_height=$height[$i];
$save_as=$dir."tn_".$file;
createFixedCropThumbnail($dir."/$file",$dir."/tn_".$file,$new_width,$new_height);
}
}
fclose($handle);
$str.="<table>\n";
$str.="<tr>\n";
for($j=0;$j<$l;$j++)
{
$str.='<td><a href="'.$img[$j].'"><img src="tn_'.$img[$j].'" border="0"></a></td>';
}
$str.="</tr>\n";
$str.="</table>\n";
$page=$dir."index.php";

The html output:

<table>
<tr>
<td>repeated image tag that's been thumbnailed</td>
<td>repeated image tag that's been thumbnailed</td>
<td>repeated image tag that's been thumbnailed</td>
<td>repeated image tag that's been thumbnailed</td>
</tr>
</table>

Is there a way I can make the html output generate the same image html page so the output would look like this:

<table>
<tr>
<td>repeated image tag that's been thumbnailed</td>
<td>repeated image tag that's been thumbnailed</td>
</tr>
<tr>
<td>repeated image tag that's been thumbnailed</td>
</tr>
</table>

Your code is incredibly complicated for such a simple task...just use regular expressions. For example, the following regular expression will match each of your "identifiers":

%image\.([0-9]+)\.([0-9]+)%

The easiest way to do this would be using preg_replace_callback ( http://www.php.net/manual/en/function.preg-replace-callback.php ). If you are unfamiliar with regular expressions then there is an excellent tutorial at http://www.regular-expressions.info/ These aren't too difficult to learn and can help you greatly with fast text matching and replacing scripts.

I've been re-reading the article and examples and it is still confusing to me.

Ok, well I'll give you some sample code:

<?php
$file = 'wherever.txt';
$data = file_get_contents($file);

function image_replace($match){
    $img_height = $match[1];
    $img_width = $match[2];
    //do whatever you're going to do with them
    return 'IMAGE'; //return a value to replace your identifier
}

$data = preg_replace_callback('/%image\.([0-9]+)\.([0-9]+)%/i', 'image_replace', $data);

echo $data; //output the data
?>

It's fairly simple, it just looks for your identifiers and replaces them with "IMAGE". Regular expressions can be difficult your first time but most people tend to find after a while they understand it all (if you read a lot of tutorials, you can learn most of it in a few days). I hope this helps in some way...

I thank you for letting me use your example scross. I tried applying it but I'm running into a small problem. It will generate correctly but it doesn't apply the $img[$j] variables. My knowledge limits me to only use the "for" below

for ($j = 0; $j < $l; $j++) {
          $str .= '<a href="' . $img[$j] . '"><img src="tn_' . $img[$j] . '" border="0"></a>';
      }

      function image_replace($match)
      {
          $img_height = $match[1];
          $img_width = $match[2];
          //do whatever you're going to do with them
          //return a value to replace your identifier
          return '<a href="' . $img[$j] . '"><img src="tn_' . $img[$j] . '" border="0"></a>';
      }

  $str = preg_replace_callback('/%image\.([0-9]+)\.([0-9]+)%/i', 'image_replace', $contents);

  /*WHAT I ORIGINALLY USED TO CALL EACH OF THE IMAGE

  for ($j = 0; $j < $l; $j++) {
      $str .= '<a href="' . $img[$j] . '"><img src="tn_' . $img[$j] . '" border="0"></a>';
  }

  */

I don't understand what you're trying to do...where does the $img variable come from??

Sorry, forgot to attach the rest of the code:

foreach ($pageexplode as $a) {
          $d = explode("%", $a);

      foreach($d as $e);
      {
          $x = explode(".", $d[0]);
          if (isset($x[1])) {
              //  echo $x[0] .  $x[1] . "<br>";
              $width[] = $x[0];
              $height[] = $x[1];
          }
      }
  }
  //foreach ends
  //checcking image in posted folder
  $img = array();
  if ($dh = opendir($dir)) {
      while (($file_name = readdir($dh)) !== false) {
          if ((substr($file_name, strlen($file_name) - 4) == '.jpg') && (substr($file_name, 0, 3) != 'tn_')) {
              $img[] = $file_name;
          }
      }
  }
  $l = count($width);
  $new_files = array();
  $images = "";
  for ($i = 0; $i < $l; $i++) {
      if (isset($img[$i])) {
          $file = $img[$i];
          list($old_width, $old_height) = getimagesize($dir . $file);
          $new_width = $width[$i];
          $new_height = $height[$i];
          $save_as = $dir . "tn_" . $file;
          createThumb($dir . "/$file", $dir . "/tn_" . $file, $new_width, $new_height);
      }
  }
  fclose($handle);

Tried a few things but it doesn't seem to work.

Can anyone crack an egg on this one?

I've spent 3 whole days and still haven't figured it out. The less sleep I get, the slower I become to figuring this out. 🙁

Finally! After hours and hours of testing and learning, I got it to work.
