Textpattern Support Forum

I just discovered a problem with the site on hblack.net

On the previous server set up, the home page was displaying a random image in the background. For that I was using a script and was calling it with background: url('<?php include("ri.php");?>');. Now that includes are not accepted I tried using background: url(<?php echo file_get_contents('ri.php');?>); but again, nothing is parsed.

this is the php script

<?php
$your_dirname="rando/";

$your_alt_tag="hb";
//
/*

*/
p. function displayAaPHPrandomImage($dirname, $alt){
  $dirhandle = opendir($dirname);
  while (false !== ($file = readdir($dirhandle))) {
    if ($file != "." && $file != ".." && !@is_dir($file)) {
      $filelist[] = $file;
    }
  }
  closedir($dirhandle); 

  if(sizeof($filelist) ==0) { 
    echo "No file was found in the directory!";
    exit;
  }

  srand((double)microtime()*1000000);
  $picnum = @rand(0, sizeof($filelist) - 1);
  $imageName=$dirname.$filelist[$picnum];
  $imageSize = getimagesize($imageName);

$result="$imageName";
return $result;

  }
?>
<?=displayAaPHPrandomImage($your_dirname)?>

Can anyone point me as to what might be going wrong?

Are not accepted where? Includes are accepted, valid. If you are referring to previous mentions concerning rah_external_output, those where about non-local filesystem files, where actual content where transferred over internet.

file_get_contents

File_get_contents is a file function and just merely reads files. include on the other hand is for evaluating PHP source code. file_get_contents will not evaluate (i.e. execute) any code, it just reads files.

<?php […] ?>

Let’s start with the tags. Use of raw PHP is deprecated, and the support will be removed in the next release, Textpattern v4.5.0. Instead of those, please see and use <txp:php> tags when working with PHP block in page and form templates.

nothing is […] what might be going wrong?

Try to turn Debugging mode on. Potentially one the file paths could be incorrect (using absolute paths might not hurt), or you may not have rights to the directory.

As the random image script goes, you probably could minify it something much more smaller and put it into a single PHP in your page template. For example:

background: url('/rando/<txp:php>
	$f = array_filter((array) glob(txpath.'/../rando/*.{png,jpg,gif}', GLOB_NOSORT|GLOB_BRACE), 'is_file');
	echo $f ? basename($f[mt_rand(0, count($f)-1)]) : '';
</txp:php>');

Edit. glad you got it sorted. Seems you migrated to Textpattern’s own image management and <txp:images /> tag or similar :)

OK… :) There are still problems.

On forum.neme.org I have a little file which calls for rah_external_output.

I used to be able to get it by using <?php include($DOCUMENT_ROOT . "http://mysite.tld/?rah_external_output=bar"); ?> but not any more.

// does not work (the whole forum page goes white)
<?php include($DOCUMENT_ROOT . "http://mysite.tld/?rah_external_output=bar"); ?>

// same as above
<?php include 'http://mysite.tld/?rah_external_output=bar'; ?>

//same as above
<?php include("http://mysite.tld/?rah_external_output=bar"); ?>

// semi works as the forum page is rendering but the external output is not fetched
<?php echo file_get_contents('http://mysite.tld/?rah_external_output=bar'); ?>

any advice would be appreciated

Try using Curl

I had a similar problem a few years ago with get_file_contents and include, both of which had been turned off or something on the server and the admins told me to use Curl…. I did, and it worked.

Not sure on the technicalities though

[SOLVED]… I had an include in my rah page which I forgot to change.
