Summary17481: Error adding a large number of answer options (max_input_vars needs to be higher in LS5)
Description

Error adding large number of answer options to single choice questions

I checked with the types: List (Drop down) and List (radio)

When adding a large number of answer options to single-choice questions, some (1 or 2) of the answer options do not appear and others are out of order

Steps To Reproduce

I experimented with answer options with very simple texts: 1, 2, 3.....
Tests I made:

Test 1 - With 200 answer options - instead of 70 the 145 appeared (the answer option "70" disappeared)
Test 2 - with 150 answer options - it worked
Test 3 - with 175 answer options - it worked
Test 4 - With 190 answer options - instead of 65 appeared 169 (answer option "65" disappeared)

This situation was reported by a user of ours who is implementing a survey and one of the questions has a dropdown list with the 308 Portuguese councils

TagsNo tags attached.

Is the problem happening when you're saving or when you're adding them?

I am able to import the 308 Portuguese councils into a dropdown list. I attached a sample question with the 308 entries.

The issue is to tell if (or not) the answer options that you have on your question on LS are the same (and that is no one missing) regarding the ones that you added on Quick Add.

The 308 Portuguese councils you have in your example : have you checked that ALL the councils you added are on the answer options (that's the issue)? That's way I've made the tests with very simple texts that I can easly detect some missing. BTW, the language you used in your survey is french and it must match the base language on my survey so I can import the question. I've made a new survey wtith french as the base language, imported your question with sucess but that does not answer the issue . I don't know the lines that you have "pasted" on your answer options with "quick add"

Maybe you should send us a list "simple text", so we can try to re-produce the issue

But with with max_input_vars at 1000 (default)
in 3.X : ~200 answer is OK
5.X : ~200 answer is not OK

OR :
In 3.X : ~200 answer + ~200 subquestion : OK
5.X : 200 answer + 200 subquestion : not OK

Because in 5.X : we send : answers + subquestions + settings + question model

Define « too small» …

Maybe : adding a POST at end of each post request and test if it' there ?

But here : 3X is better than 5.X. Something working in 3.X didn't work with 5.X

You can hash the post on JS, then hash it again in PHP and compare. Not equal == messed up.

Seems clearer to add a simple post at end of the forum in my opinion.

Here : you need to disable submit and do your submit in JS : a lot of error can happen.

What do you mean?

HTML :

<input type="hidden" name="checkAllPosted" value="1">
</form>

ONLY at end of the form

PHP :

if(empty(App()->getRequest()->getPost('checkAllPosted')) {
App()->addFllashMessage("All values are not posted : please check max_input_vars");
}

More specific :
Seems there are something started in 5.X :

But here : in my opinion : need to separate answers and subquestion_X subquestion_Y.
With array : bFullPOST is set in subquestion before set in answers : then tested only for subquestions, not for answers.

Hi,

I apologize for the delay in my reply, just returning from summer holidays.

Which two? Which are so special about those? :)

Nothing special about those two. The answer options are just a sequence : 1, 2, ...,308

Is it the same data as you pasted above?
Yes

Done a new test (now on version 5.1.3+210817) just with 308 answers options . The answers options are 1,2,3, 4, ...,308

I've pasted those 308 values and the result is:
answers options 3, 8,149, 187, 189 are missing

answers 40, 35, 265, 203, 288 appears at the place of the missing answer options

No, I can't.

Trying to add a missing option (clicking in the "+" - "Insert a new answer otion after this one"), inserted a new answer option and when I clicked in the button "Save" an error message appeared:

code is not set in data: {"oldcode":"AO250"}

PR: https://github.com/LimeSurvey/LimeSurvey/pull/2026

Moved and started to re-use the bFullPOST to show a warning message if some fields are not processed because of max_input options being too small.

The answerOptions.twig and subquestions.twig views had the hidden "bFullPOST" field, but was not being checked.
Database.php used to check it, but seems that mechanism "got lost in translation".

Moved the bFullPost field to create.php following the new screen reorganization (subquestions and answers editable on the main screen)

Hi,
Done some further tests.

Scenario 1:
If I "ADD" (not Replace) the 308 answer options when adding the 308 Answer Options are ALL there . But when I click on "Save" the error persists:
"An error happened: Could not save answer option Array ( [code] => Array ( [0] => Code is too long (maximum is 5 characters). ) )"

Scenario 2:

If I choose "Replace" (instead of "Add") the 308 answer options when adding the 308 Answer Options are ALL there and when I click on "Save" it works fine and the 308 Answer Options are ALL there. Everything is correct.

I am sending a video with scenario 1
