In order to upload files without using WebDAV you can work with HTTP connections. To do so, you have to activate the HTTP POST mechanism within the configuration file and specify a server-side script.

The first step is to activate the HTTP POST upload mechanism for images, multimedia objects and documents in the "config.xml" file, e.g.:

...

<filemanagement>

      <file type="image" baseurl="http://www.myserver.com/"

       autoupload="true"

       onuploadfinished="uploadStatusReport">

       <http url="http://www.myserver.com/upload.php" />

      </file>

      <file type="object" baseurl="http://www.myserver.com/"

       autoupload="true">

       <http url="http://www.myserver.com/upload.php" />

      </file>

      <file type="document" baseurl="http://www.myserver.com/" >

       <http url="http://www.myserver.com/upload.php" />

      </file>

 </filemanagement>

...

Then you have to specify a server-side script which manages the file upload. By uploading files using the HTTP POST upload mechanism (see above), every file will be kept in a form field called "uploadfile". To make sure that the file was uploaded successfully, the server-side script must return "OK" resp. "Failed" if not.
Below please find a sample for the image upload:

...

 <?php

 $filename = $_FILES["uploadfile"]["name"];

 $tmp_name = $_FILES["uploadfile"]["tmp_name"];

 if(file_exists($filename)) {

       while(file_exists($filename)) {

          $ext = strchr($filename,".");

          $pos = strpos($filename,".");

        $filename = substr($filename,0,$pos)."$".$ext;

       }

 }

 if($fp = fopen($tmp_name,"rb")) {

       $file = fread ($fp, filesize($tmp_name));

       fclose($fp);

 } else

       die("Failed");

 if($fp = fopen($filename,"wb")) {

       fwrite($fp,$file);

       fclose($fp);

 } else

       die("Failed");

 echo "OK";

 echo "|http://yourserver.com/eop4".$filename."|";

 ?>
