PHP Session Variables Not Saved in Centos Linux? -

i having php script fails save session variable when nail submit in php version 5.1.6 linux centos system. problem happens on time. temporary solve problem php rebooting machine. however, not solution. temporary solution.

here php session info:

directive local value master value session.auto_start off off session.bug_compat_42 off off session.bug_compat_warn on on session.cache_expire 180 180 session.cache_limiter nocache nocache session.cookie_domain no value no value session.cookie_lifetime 0 0 session.cookie_path / / session.save_path /var/lib/php/session /var/lib/php/session session.serialize_handler php php session.use_cookies on on session.use_only_cookies off off session.use_trans_sid 0 0

under php core:

directive local value master value open_basedir /var/www/domain.com/httpdocs/public_html/:/tmp/ no value

i suggest why rebooting machine solves temporary php session variables not saved.

my php code uses session variable check if captcha values solved when nail submit button. check shown below done when page reloads after submit hit.

<?php session_start(); if($_session['captcha_keystring'] == $_post["keystring"]){ } // end: if capcha verification else { echo "wrong capcha entered!"; } ?>

even when captcha_keystring solved fails.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
