php - Processing an unknown amount of checkboxes -

i'm generating unknown amount of checkboxes in form using mysql, number vary,

$frinfoq = mysql_query($frinfo) or die (mysql_error()); while($frow = mysql_fetch_assoc($frinfoq)) { $username = $frow['username']; $ct = $frow['country']; $fruuid = $frow['uid']; ?> <tr><td><p><?php echo $username; ?></p></td><td><p><?php echo $ct; ?></p></td><td><form method="post" action="<?php echo $_server['php_self']; ?>" id="delf"><input type="hidden" value="<?php echo $fruuid; ?>" /><input type="checkbox" name="add[]" value="<?php echo $fruuid; ?>" id="a_t_game" /><form></td></tr> <?php } ?>

when form submitted , processed "create.php" it's supposed add together checked users mysql table, row per user, determine (i'm not sure if works due problem i'm to) checked this:

if($_post['add'] == true) { $user_uid = $_post['add']; }

i seek add together rows so:

$arr = array($user_uid); foreach($arr $user_uid) { $game = "insert wd_game (game_uid,user_uid,lastmove,startcountry) values ('$gid','$user_uid',now(),'none')"; $gameq = mysql_query($game) or die (mysql_error()); }

all of info inputs fine apart user uid set "array". creates 1 row, , need row per user.

i know it's problem way array beingness processed, that's pretty obvious, haven't foggiest thought how prepare it. help/pointers great help!

$arr = array($user_uid); problem. seek $arr = $user_uid;, or cutting out middleman , utilize $arr = $_post["add"];.

edit

there number of other things improved code. one, it's hard read. suggest cleaning bit, , avoid jumping between html , php.

another thing should escape info going database perchance come user input (like $_post). should utilize mysql_real_escape_string.

a 3rd thing form action pointing $_server["php_self"] not safe. vulnerable cross-site scripting (xss). see this blog more detailed description on vulnerability.

i suggest more this:

<?php if ($_post["add"]) { $arr = $_post["add"]; foreach ((array)$arr $user_uid) { $game = "insert wd_game (game_uid,user_uid,lastmove,startcountry) values ('". mysql_real_escape_string($gid) ."','". mysql_real_escape_string($user_uid) ."', now(), 'none')"; $gameq = mysql_query($game) or die (mysql_error()); } } $frinfoq = mysql_query($frinfo) or die (mysql_error()); while($frow = mysql_fetch_assoc($frinfoq)) { $username = $frow['username']; $ct = $frow['country']; $fruuid = $frow['uid']; echo " <tr> <td> <p>{$username}</p> </td> <td> <p>{$ct}</p> </td> <td> <form method=\"post\" action=\"". htmlentities($_server['php_self']) ."\" id=\"delf\"> <input type=\"hidden\" value=\"{$fruuid}\" /> <input type=\"checkbox\" name=\"add[]\" value=\"{$fruuid}\" id=\"a_t_game\" /> <form> </td> </tr>\n"; } ?>

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...
