RE: correction ... [PHP-DB] Time Consuming DB-Transaction

the theory is using javascript, every time u make an operation, must increment a load bar must have : .... a table sort like this on the page where u are processing ... <table width="600" border="0" cellspacing="0" cellpadding="0"> <tr> <td bgcolor="#000066" width="<?=$percent ?>%" height="20" name="progresso" id="progresso"> <div align="right"><font color="#FFFFFF"> </font></div> </td> <td bgcolor="#0066FF" width="50%" height="20">&nbsp;</td> </tr> </table> notice the NAME & ID assigned .... while not end of CVS file, do the operations and output this : <script language="JavaScript"> document.all.progresso.width ='<?=$percent + 1 ?>%' </script> this will make the bar 'increment' u must calculate the percent wich is current_operation/Total_operations , before the cycle ex.: 1. read line from CVS 2. insert into db ( or whatever ) 3. increment bar 1. read line from CVS 2. insert into db ( or whatever ) 3. increment bar and so on the thing is that u most know how many lines ( operations ) will occur to calculate the percentage -----Mensagem original----- De: Hannes Wyss [mailto:hwyss@ywesee.com] Enviada: segunda-feira, 17 de Junho de 2002 9:38 Para: php-db@lists.php.net Assunto: [PHP-DB] Time Consuming DB-Transaction Hi list, I need to provide the facility to upload a large csv-file (>800kb) to my customer, do some expensive string comparison stuff (cut off empty lines or superfluous fields - Excel-Generated csv seems to be unpredictable in some cases; convert some of the fields - '3%' -> 3) and then load the file or insert each row into a postgres backend. This takes anywhere between 20 secs and 90 secs at the moment, and the file is likely to grow in the near future. How can I provide feedback to the user while keeping the db-transaction running and providing rollback facilities in case of a failure? tia.
