php - smarty grammer error cannot use symbol [] -

-

this line:

{$data["bank_data"]["arrangement"]["id"]}

returns following error:

php (5.3.9) error (e_user_error):
file: smarty.class.php
line: 1092
type: smarty error: [in tke-g-admin_scopeofwork.tpl line 10]: syntax error: unrecognized tag: $data["bank_data"]["arrangement"]["id"] (smarty_compiler.class.php, line 446)

this line:

{$data.bank_data.arrangement.id}

does not return error. works correctly.

so, why first section wrong? how use [] access array.

judging error posted, you're using smarty2. the docs give 2 options accessing arrays:

{* string indexes *} {$some.array.value} {* numeric indexes *} {$some[0][1]}

you can use variable provide index so

{assign var="key" value="array"} {$some.$key.value} == {$some.array.value}

using "trick", can access string indexes containing "special characters" such ., [] or .

smarty3 bit more flexible in way:

{$some.{"hello world"}.array["array"]['foo']}

oddly enough {$foo[bar]} not parsed (in smarty 3.1.10). threw on todo list, though.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
