[PHP-DEV] [PATCH] upload progress metter
Hi, To make a long story short, I needed an upload progress metter, so the users will something while their huge files are uploaded to the server. I searched the net but only found for ASP, so I wrote one. Unfortunatly PHP needs a little patch to be willing to do this ... Here is how it works: 1. apply patch to php and recompile php (and apache if needed) 2. add something like this to http.conf #for php-upload-progress-bar Directory /www/htdocs/upload php_value upload_metter 1 php_value upload_metter_dir /tmp/uploadbar /Directory - This will activate the progress metter for /upload - And will tell it to write progress informations to /tmp/uploadbar 3. mkdir /tmp/uploadbar; chmod 777 /tmp/uploadbar I have to say that 0777 and /tmp are not the best choises from a security point of view. you should find a better place! 4. copy the demo scripts to /upload directory 5. point your browser to the index.php script. upload some files. enjoy! Here is how it really works: 1. index.php will generate and uniq ID for each upload. This ID will be used to track the progress and report it. 2. a special field named 'UPLOAD_METTER_ID' is used to store this ID. make sure this field is BEFORE any 'file' fields. put it at the begining of the form! 3. onSubmit()-ing the form a small window will open where the progress.php will display the actual progress bar. 4. php will check the value of 'upload_metter' and 'upload_metter_dir' configuration options and the presence and value of 'UPLOAD_METTER_ID' field 5. the progress file is stored in the directory named by 'upload_metter_dir' and the vlaue of UPLOAD_METTER_ID field is used as the name of the file 6. progress information is updated once a second by the php engine 7. script progress.php will use the ID field which it receives as a parameter to locate the associated progress-file and read progress information from it. then generate the little proggress bar 8. the progress bar will 'refresh' about once a second, depending on how fast the network is going 9. when upload is completed, the progress.php script will remove the progress file, and close the pop-up window. NOTE: there is a good chance that this progress files will not be deleted from various reasons (client don't have JS activated, or it closes the popup while data is still uploaded, etc...), so there is a need to periodically cleanup the directory of old files. What the PATCH does: - adding 2 new cinfiguration options to PHP: upload_metter and upload_metter_dir - in rfc1867.c: changes rfc1867_post_handler() to make some calls to a newly defined function that will update the progress metter: update_progress_metter() - in turn it calls update_progress_metter_file(), trying its best not to update the file more than once a second. I have tested it with php-4.2.3 and 4.3.2. atch for php-4.3.2 is attached. a patch for 4.2.3 is also available. basically is the same thing. the rest of the files and a live demo can be found here: http://pdoru.from.ro/ Please let me know if you have any problems/suggestions :-) Best regards, Doru Petrescu Senior Software Engineer Astral Telecom Bucuresti --- diff -rubB orig/php-4.3.2/main/main.c php-4.3.2/main/main.c --- orig/php-4.3.2/main/main.c Thu May 22 01:54:38 2003 +++ php-4.3.2/main/main.c Thu Jun 5 22:58:46 2003 @@ -345,7 +345,9 @@ STD_PHP_INI_BOOLEAN(file_uploads, 1, PHP_INI_SYSTEM, OnUpdateBool, file_uploads, php_core_globals, core_globals) STD_PHP_INI_ENTRY(upload_max_filesize,2M, PHP_INI_SYSTEM|PHP_INI_PERDIR, OnUpdateInt, upload_max_filesize,php_core_globals, core_globals) STD_PHP_INI_ENTRY(post_max_size, 8M, PHP_INI_SYSTEM|PHP_INI_PERDIR, OnUpdateInt,post_max_size, sapi_globals_struct,sapi_globals) - STD_PHP_INI_ENTRY(upload_tmp_dir, NULL, PHP_INI_SYSTEM, OnUpdateStringUnempty, upload_tmp_dir, php_core_globals, core_globals) + STD_PHP_INI_ENTRY(upload_tmp_dir, NULL, PHP_INI_ALL,OnUpdateStringUnempty, upload_tmp_dir, php_core_globals, core_globals) + STD_PHP_INI_ENTRY(upload_metter, 0, PHP_INI_ALL,OnUpdateBool, upload_metter, php_core_globals, core_globals) + STD_PHP_INI_ENTRY(upload_metter_dir, NULL, PHP_INI_ALL,OnUpdateStringUnempty, upload_metter_dir, php_core_globals, core_globals) STD_PHP_INI_ENTRY(user_dir, NULL, PHP_INI_SYSTEM,
RE: [PHP-DEV] [PATCH] upload progress metter
I also developed upload status capability for my company that works very similarly to yours. I am currently working on integrating the changes I made into a patch for 4.3.2 for members of this list to evaluate (I originally made the upgrade to 4.1.2). I see you came to the same conclusion I did, that the easiest way to pass information seemed to be through the use of temporary files. I was hoping that once I submitted my patch that someone on this list might have a better suggestion like direction on using shared memory or something. --David -=+=- David Enderson Programmer Digital IMS 402.437.0137 [EMAIL PROTECTED] Hi, To make a long story short, I needed an upload progress metter, so the users will something while their huge files are uploaded to the server.
