php - Add dynamic string in moodle form help icon -

i new in moodle. have requirement add dynamic text in icon created using $mform->addhelpbutton(); function. not able this.

can tell me way pass dynamic string in moodles form icon.

the addhelpbutton() method has parameter $component contains current text shown when clicking onto icon (). text read $string array defined in language file.

the trick here array element can built dynamically:-)

let's make example: in mod_form.php build icon with:

$mform->addhelpbutton ( 'element_name', 'your_identifier', 'your_help_text' ); 

the text your_help_text read in language file with:

$string ['your_help_text_help'] = 'this static text'; 

here change line with:

$string ['your_help_text_help'] = get_dynamic_help_string($any_parameter); 

and define function:

function get_dynamic_help_string($any_parameter) { $text = dynamic text current date: ; $text .= ' '.date("y/m/d"); return $text; } 

now, time refresh form, text built dynamically. of course, can use logic here, if want.

note: need here manage cache of plugin in order newest result of function. please, refer link deleting moodle cache.
