Fix it. Kind Regards Florian Engelhardt Previous Comments: [2005-11-11 08:51:46] [EMAIL PROTECTED] Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php from http://www.php.net/mysql_stmt_bind_param Character Description b corresponding variable is a blob and will be send in packages For sending a blob in packages, you have to use mysql_stmt_send_long_data. If you don't want to do this (e.g. your data doesn't need escaping and is < max_allowed_package) use type "s" (=string). [2005-11-09 16:07:10] f dot engelhardt at 21torr dot com This Problem is very annoying, becouse i am using innodb tables with foreign key constraints, and if i use mysqli_stmt_send_long_data() for any of the fields, all the other arent NULL anymore. So my constraint fails! Example: without mysqli_stmt_send_long_data() i have the problem as described, and with mysqli_stmt_send_long_data() on the blob field, mysql tells me, that the constraint gets violated! This can only happen, if the variables $one and $two are not NULL. [2005-11-08 23:28:54] [EMAIL PROTECTED] Assigned to the maintainer. [2005-11-08 23:26:59] f dot engelhardt at 21torr dot com it doesn´t work, but the behavior changed a little: Every insert without mysqli_stmt_send_long_data() inserts 0 Bytes into the blob field, with this function it works as in the other version (5.0.5) [2005-11-08 17:43:53] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip The remainder of the comments for this report are too long.

ID: 35155 User updated by: f dot engelhardt at 21torr dot com Reported By: f dot engelhardt at 21torr dot com -Status: Bogus +Status: Open Bug Type: MySQLi related Operating System: Linux 2.6 PHP Version: 5.0.5 New Comment: it seems to work with mysqli_stmt_send_long_data(), but it has to work without, as the doc says, you only have to use it, if you send data larger than max_allowed_packet. This value is set to 16M, that data is only 2mb. Kind regards Previous Comments: [2005-11-08 17:06:19] [EMAIL PROTECTED] RTFM: http://www.php.net/manual/en/function.mysqli-stmt-send-long-data.php [2005-11-08 15:29:36] f dot engelhardt at 21torr dot com Description: Inserting a data into a blob column only inserts some of the data, in most cases between 1 and 200 Bytes, but not allways the same and never all data (which is in this case about 2 mb). I also tried it with mysqli_stmt_send_long_data(), but that was not working either. The table is as followes: CREATE TABLE `dbfs_data_chunk` ( `fileid` smallint(5) unsigned NOT NULL, `version` smallint(5) unsigned NOT NULL default '0', `data` mediumblob, PRIMARY KEY (`fileid`,`version`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; MySQL-Version: 5.0.15 If i do a base64_encode() it works, but this isn´t a solution, only a bad workaround, which is not acceptable. I also tried MyISAM, the same result. Reproduce code: --- Expected result: Should insert the binary data into the table Actual result: -- only 1 to 200 Bytes get inserted. -- Edit this bug report at http://bugs.php.net/?id=35155&edit=1
