Note: Since I'm using some custom validation, I cannot use Knop's builtin -required parameter for the rendering template on these fields, so I have to do some janky code workaround. --steve -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Steve Piercy Web Site Builder Soquel, CA <web@...> <http://www.StevePiercy.com/> -- ############################################################# This message is sent to you because you are subscribed to the mailing list <knop@...>.

>I'm struggling with displaying error messages next to each field, insted of at the >top or bottom of the form. Is there an example somewhere? I've modified this slightly such that I can now insert many error messages into an array, then display each message in a list. The display checks for default Knop error messages, extended language types with error codes and messages, or simple custom strings. See attached screenshot for example. Just another example of how nifty Knop is. cfg_file.inc ---------------------------- $f -> error_lang -> insert(-language='en', -key=9001, -value='Must contain letters or numbers only.'); $f -> error_lang -> insert(-language='en', -key=9002, -value='Must be at least 8 characters in length.'); var('v_username'={ local('result'=array); // when size is evaluated, if 0 then it is okay if(params -> size < 1); #result ->insert('Must not be empty.'); /if; if(string_findregexp(params, -find='[^a-zA-Z0-9]')); #result ->insert(9001); /if; if(params -> size < 8); #result ->insert(9002); /if; #result->size==0 ? #result = 0; return(#result); } ); $f -> addfield(-name='username', -label=$lang_ui -> username, -type='text',-validate=$v_username, -focus); cnt_file.inc ---------------------------- // janky method to display error messages inline with each field loop(-from=1,-to=4); '<p>'$f -> renderform(-from=loop_count, -to=loop_count); // exclude the submit button from having a * at the end loop_count < 4 ? '<span class="required">*</span>'; if($f -> errors -> find($f->keys->get(loop_count))->size > 0); // we gots errors! oh noez! '<span class="error_message"> '; iterate($f -> errors -> find($f->keys->get(loop_count)),local('i')); if(#i -> isa('pair')); // display custom knop error messages iterate((#i -> second),local('j')); if(#j -> isa('integer')); // by extending the language type and using an error code and message $f -> error_msg(-error_code=#j) + '<br />'; else; // by using a custom string for the error message #j + '<br />'; /if; /iterate; else; // display default knop error messages ("required") ' Must not be empty.<br />'; /if; /iterate; '</span>'; /if; '</p>'; /loop; --steve -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Steve Piercy Web Site Builder Soquel, CA <web@...> <http://www.StevePiercy.com/> -- ############################################################# This message is sent to you because you are subscribed to the mailing list <knop@...>.
