[Chameleon] Manage WMS Servers widget shows "cache_mlt" errors,r esults in no WMS data layers

[Eijnden, B. van den (Bart)]

Hi Jacob,

do I get it correctly that these lines of code are only executed if:

1) the Chameleon php module cannot be found/loaded
2) the wmsparse utility cannot be found

so then the code reverts to the slow parsing of WMS capabilities in PHP? I
think this was never adapted for the scale/metadataURL enhancement. I have
no problem with your change then.

For us this is never a use case, since we used to use 2) for the parsing,
but now use 1). The Chameleon PHP extension is present in chameleon/ext in
CVS, and does the same job as wmsparse, but because of security it does not
use CGI but a PHP module.

Jennifer, if you are interested, we use the following PHP script to generate
the dbf files automatically from a | separated textfile of: servername|URL

<?php

define( 'COMMON', '/data/geoservices/apps/chameleon/htdocs/common/' );
define("LAYER_STYLE", true);
$szDataDir = '/data/geoservices/apps/mapviewer/data/';
$szWMSParse = COMMON.'wmsparse/linux/wmsparse';
$szFile= '/data/geoservices/apps/geoservices/config/wmsbrowser.txt';
include_once('/data/geoservices/apps/chameleon/htdocs/common/phpwms/manage_s
ervers.php');

// use curl for http communication
$_SESSION['HTTPClientType'] == 1;

$oServerManager = new ServerManager( $szDataDir, $szWMSParse );

// read file and for every line add entry to server manager
$fp = fopen($szFile, 'r');
$i = 0;
while (!feof ($fp))
{
  $line = fgets($fp, 4096);
  // format is Name|URL
  $array = explode('|', $line);
  echo "+ $array[0] => $array[1]";
  if (trim($array[0]) != "")
  {
    $oServerManager->add($array[1], $array[0], $i);
  }
  $i++;
}
fclose ($fp);
?>

Best regards,
Bart

Hi Bart,

I'm not familiar with that extension. I guess this extension makes use
of the fields added in dbf.php?

To prevent changing the DBF structure from what it currently is, can I
suggest the following changes to server_data_manager.php instead?

Line 1807, after:
$rec_new = array( $nLayerID, $nServerID, $szName, $szTitle, $szSRS);

Add this line:
$rec_new = array_merge($rec_new, array("","",""));  // values for
mdu_type,mdu_fmt,mdu_url

Change line 1813, from:

$rec_new = array_merge($rec_new, array($ll_minx, $ll_miny, $ll_maxx,
$ll_maxy, $bb_id));

To

$rec_new = array_merge($rec_new, array($ll_minx, $ll_miny, $ll_maxx,
$ll_maxy, "","", $bb_id));
// fill blanks for missing minscale and maxscale


These lines mean the DBF stays the same, but the record added to it has
blanks for the field for which values are not added. I don't think this
would cause any problems for anyone, as currently the code tries to add
an invalid record to the DBF, with too few fields. It appears to work
for me.

Jennifer, if this causes incompatability with your old DBF, maybe you
could edit your DBF by adding fields to it, so it can be used with the
new structure. 

Regards,

Jacob
