[closed] limit number of fields by user

    This is what I would like to accomplish...say you have 50 drop down fields and you only want a user selecting a response for 10 of them, where do I start?

    I am assuming there is an easy function to see if a field is empty or not. Similar to the checking in place for required fields, I want to count how many fields are empty and prevent the user from submitting if it is more or less then I say so. In the example above I would want to have a total of 40 empty fields...no more no less.

    Could you see a function like this work in this environment?

    Hi ..

    From your case you only want user to fill 10 from 50 Drop down right? you can try this modification to your machform :

    1. modify includes/post-functions.php

    #bellow line 131 

    //count variable
$selectRequiredCount = 0;

    #between line 630 ~ 632, replace

    if($validation_result !== true){
   $error_elements[$element_id] = $validation_result;
}

    to

    //add rule blank check
$rules[$element_name]['blank'] 	= true; 

if($validation_result !== true){
	if ($validation_result !== "BLANK")
		$error_elements[$element_id] = $validation_result;
	else
		$selectRequiredCount++;

}

    #in line 948, add

    if ($selectRequiredCount <> 40) {
	$process_result['status'] = false;
	$process_result['custom_error'] = "you must fill 10 entries";

	return $process_result;
}

    2. modify include/common-validator.php

    #in line 39

    //validation for blank
function validate_blank($value){
	$value = $value[0];

	if(empty($value)) { //0  and '0' should not considered as empty
		return 'BLANK';
	}else{
		return true;
	}
}

    Wow, thanks for the quick response. It is not currently working for me. I edited the error message to output the $selectRequiredCount value. It doesn't appear that this variable is being incremented.

    Where does the new function validate_blank get called?

    Really ? have you put bellow code to include/common-validator.php , and try echo the $selectRequiredCount in line 948 it should show the value. 

    //validation for blank
function validate_blank($value){
	$value = $value[0];

	if(empty($value)) { //0  and '0' should not considered as empty
		return 'BLANK';
	}else{
		return true;
	}
}

    do you have another piece of code i need to add? i'm not too sure how everything is set up but i don't see where you called validate_blank function. $selectRequiredCount remains zero.

    if you have these two files working can you just email them to wal_ags at yahoo?

    I'm sorry my bad ..

    the code in that line supposed like this around line 630 ~ 632

    //add rules blank
$rules[$element_name]['blank'] 	= true; 

$target_input[$element_name] = $element_data;

$validation_result = validate_element($target_input,$rules);

if($validation_result !== true){
	if ($validation_result !== "BLANK")
		$error_elements[$element_id] = $validation_result;
	else
		$selectRequiredCount++;

}

    man yall are good. at a minimum yall should have a paypal donate button for custom stuff like this.

    i don't see it being an issue since i will only have one form active at a time, but can i limit this new requirement to a specific form number?

    you can change this code 

    $rules[$element_name]['blank'] = true;

    to

    if ($form_id == 1) {$rules[$element_name]['blank'] = true; }

    and thank you for suggestion :D
