#27631 [NEW]: dynamically generated form elements using name=foo[] submitted out of order

From: phpclass at oneroad dot com Operating system: Windows 2000 PHP version: 4.3.4 PHP Bug Type: Arrays related Bug description: dynamically generated form elements using name=foo[] submitted out of order Description: ------------ When submitting a form with elements named using an array (e.g.: name="foo[]"), the elements appear to be sent in the order in which the elements are created, and not the order in which they appear in the form's DOM tree. This can cause information to be sent in a mixed order when the elements are created in a different order using DOM routines. Reproduce code: --------------- See http://www.oneroad.com/test/phpbug.phtml to run the code, or http://www.oneroad.com/test/dombug.phps to view it (about 40 lines). (This server is running 4.0.6, but I have reproduced the bug in 4.3.4 as well.) To reproduce: (1) click "addrow" (2) choose "1" in the first field, and type "abc" in the second field (3) click "addrow" (4) choose "2" in the first field, and type "def" in the second field (5) change the first select field to "3". (6) enter "abc" in the second field of the first row. (7) click "go" Expected result: ---------------- The $_GET array should contain the following: Array ( [go] => go [field1] => Array ( [0] => 3 [1] => 2 ) [field2] => Array ( [0] => abc [1] => def ) ) Actual result: -------------- The $_GET array contained the following. Note the "field2" elements were sent in the reverse order, because the element in the first row was dynamically generated *after* the element in the second row. Array ( [go] => go [field1] => Array ( [0] => 3 [1] => 2 ) [field2] => Array ( [0] => def [1] => abc ) ) -- Edit bug report at http://bugs.php.net/?id=27631&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=27631&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=27631&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=27631&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=27631&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=27631&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=27631&r=needscript Try newer version: http://bugs.php.net/fix.php?id=27631&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=27631&r=support Expected behavior: http://bugs.php.net/fix.php?id=27631&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=27631&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=27631&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=27631&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=27631&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=27631&r=dst IIS Stability: http://bugs.php.net/fix.php?id=27631&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=27631&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=27631&r=float
