ID: 64325 Updated by: larue...@php.net Reported by: php at sygmoral dot com Summary: Issue in automatic $_POST array handling -Status: Open +Status: Feedback Type: Bug Package: Arrays related Operating System: Debian PHP Version: 5.4.12 Block user comment: N Private report: N New Comment: PHP won't allow variables name to contains "[", "." etc , so I think this is really a narrow usage. but, however I do believe there is a bug. a patch will be attached. but I need to ask someone else's opinion before commit it. thanks Previous Comments: ------------------------------------------------------------------------ [2013-02-28 19:45:57] php at sygmoral dot com Thank you for your reaction! But no: I did in fact mean what I wrote. I realise it's a strange data structure, so here's a short explanation for it: the 'save' array holds a collection of html form elements that are not yet to be submitted, but should be saved temporarily into some other set of memory, so that upon the next visit, those temporary values can be easily inserted into the displayed form, without having been submitted. In other words, it's for a form that remembers its state throughout visits. So I send an object containing the name-value pairs in the form, and send that over POST. In the example used here, this results in one or more name-value pairs that are saved into the save array, as save['line[]'] = value. And that is the situation that triggers this bug, as in my original post. I'm sure there are other ways to achieve what I want, but I figured I'd report it since this does not look as if it's intended. Note that the example is a simplification of my application, where multiple 'single' and 'array' values are saved. ------------------------------------------------------------------------ [2013-02-28 18:22:57] re...@php.net "post_data = {'save[line[]]':'A line with text'}â do you mean post_data = {'save[line][]':'A line with text'} ? ^^ is this you intention? array( 'save' => ['line' => ['A line with text', 'maybe more lines'] ] ); ? ------------------------------------------------------------------------ [2013-02-28 16:09:49] php at sygmoral dot com Description: ------------ Php automatically puts POSTed name-value pairs with names ending in [] into arrays. Very handy feature! However, I notice issues when more of those square brackets are encountered. If I send a name like `save[line[]]`, then `save` will be an array and the first key in it will be `line[`, instead of `line[]`. It's not that I expect a second level of arrays - just that it doesn't strangely remove that last bracket. So suppose we have the tiny php script below, and I send this with e.g. jquery: post_data = {'save[line[]]':'A line with text'} Effectively, the raw POST data being sent is: save%5Bline%5B%5D%5D=A+line+with+text Test script: --------------- print_r( $_POST['save'] ); Expected result: ---------------- POST: Array ( [line[]] => A line with text ) Actual result: -------------- POST: Array ( [line[] => A line with text ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64325&edit=1
