This is valid issue. Just not a bug but feature/change request. ------------------------------------------------------------------------ [2007-10-14 12:13:56] bjori@php.net 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 See bug#42162 ------------------------------------------------------------------------ [2007-10-14 10:56:53] efbiaiinzinz at hotmail dot com Description: ------------ PHP messes up coordinates for <input type="image" .. fields when fieldname is not simple one level name but multilevel name. For example name="smth[field]" is easy way to test it Reproduce code: --------------- <form action="" method="GET"><input type="image" name="smth[imgsubmit]" src="t.jpg" width="200" height="200"></form> <?php print_r($_POST); ?> Expected result: ---------------- Since single level image submits end up in post and get arrays as fieldname_x and fieldname_y I would expect above code to produce GET array as such: Array ( [smth] => Array ( [imgsubmit_y] => 80, [imgsubmit_x] => 80 ) ) or even better would be actually Array ( [smth] => Array ( [imgsubmit] => Array([x] => 80, [y] => 80) ) ) but it woul be a breaking change when changed to that and would be inconsistent with single level fields, but also it would be much clearer and would not prohibit me from having <input type="image" name="someimage" src="..."> and <input type="hidden" name="someimage_x" value="previousvalue"> fields on same form at the same time Actual result: -------------- Array ( [smth] => Array ( [imgsubmit] => 80 ) ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=42960&edit=1
