I'm just seeing an empty array! <form enctype="multipart/form-data" action='/fileupload.php' method=post> <input multiple=true type=file name='file["my{}stuff"].data'><input type=submit value='submit'></form> var_dump($_FILES) yields: array(0) {} If I change the 'action' to a python script, I see this: [ { 'file["my{}stuff"].data’, ‘testfile2.txt’, ‘this is another test file (2)\n’ }, { ‘file["my{}stuff"].data’, ‘testfile1.txt’, ‘this is test file 1\n’ } ] ] POST source: Content-Type: multipart/form-data; boundary=---------------------------141539390286251557952150290 Content-Length: 468 -----------------------------141539390286251557952150290 Content-Disposition: form-data; name="file[\"my{}stuff\"].data"; filename="testfile2.txt" Content-Type: text/plain this is another test file (2) -----------------------------141539390286251557952150290 Content-Disposition: form-data; name="file[\"my{}stuff\"].data"; filename="testfile1.txt" Content-Type: text/plain this is test file 1 -----------------------------141539390286251557952150290-- ------------------------------------------------------------------------ [2004-10-12 00:32:05] xmlguy at hotmail dot com I indicated this as an mbstring related problem because the similar bugs I found used this as the category. See bugs 20114 19507 19347 20024 20133. ------------------------------------------------------------------------ [2004-10-08 16:17:43] moriyoshi@php.net How come this could be a mbstring related problem..? ------------------------------------------------------------------------ [2004-07-27 02:44:23] xmlguy at hotmail dot com with the version of the form I posted, the expected and actual result sample data should obviously reflect the strings "John" and "Doe" instead of "billy" and "joel", respectfully. ------------------------------------------------------------------------ [2004-07-27 02:33:53] xmlguy at hotmail dot com Description: ------------ If key contains more than one set of square brackets, the key value pair is not decoded properly. For example, a form with a series of input elements named such as "formname[0].fieldname[0]" will cause incorrect and missing key/value pairs to be stored into the $_POST array. In researching the existing bug list, I noticed that there have been numerous variations of bugs reported when form data contains url encoded data, such as occurs when the brackets are encoded as %5b and %5d. However these bugs have apparently been closed without actually fixing this problem. Perhaps a more thorough analysis of this problem is warranted to keep it from lingering on for a few more years before this report is closed. The Adobe acrobat products/reader have just started to encode form names in this format, so it could become a very serious issue if PHP cannot correctly process this form data. Reproduce code: --------------- <html> <head><title>Form Submit Test Script</title></head> <body> <form name='fm1' action="<? echo ($_SERVER["HTTP_REFERER"])?>" method='post'> <input type='text' name='form1[0].firstname[0]' value='John' /> <input type='text' name='form1[0].lastname[0]' value='Doe' /> <input type='submit' /> </form> <? var_dump($_POST); ?> </body> </html> Expected result: ---------------- array(2) { ["form1[0].firstname[0]"]=> string(5) "billy" ["form1[0].lastname[0]"]=> string(4) "joel" } Actual result: -------------- array(1) { ["form1"]=> array(1) { [0]=> string(4) "joel" } } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=29401&edit=1
