Random numbers

Beginners - Learning PHP
#1

I’m new to both Laravel and php. Need some help with generating random numbers.

If checkbox 1 (exercise_choice_10) is selected a random number between 1-10 shall be generated.
If checkbox 2 (exercise_choice_20) is selected a random number between 11-20 shall be generated.
If checkbox 3 (exercise_choice_30) is selected a random number between 21-30 shall be generated.


<input type="checkbox" name="exercise_choice_10" value="10" {{ app('request')->input('exercise_choice_10') ? 'checked' : '' }}> Type 1</input></BR>
<input type="checkbox" name="exercise_choice_20" value="20" {{ app('request')->input('exercise_choice_20') ? 'checked' : '' }}> Type 2</input></BR>
<input type="checkbox" name="exercise_choice_30" value="30" {{ app('request')->input('exercise_choice_30') ? 'checked' : '' }}> Type 3</input></BR>



<form action="{{ route('exam.robot', ['course' => $course]) }}" method="post">
    <input type="checkbox" name="exercise_choice_10" value="10" {{ app('request')->input('exercise_choice_10') ? 'checked' : '' }}> Type 1</input></BR>
    <input type="checkbox" name="exercise_choice_20" value="20" {{ app('request')->input('exercise_choice_20') ? 'checked' : '' }}> Type 2</input></BR>
    <input type="checkbox" name="exercise_choice_30" value="30" {{ app('request')->input('exercise_choice_30') ? 'checked' : '' }}> Type 3</input></BR>
    </BR>
    <button class="button">Submit</button>
    </BR>
    </BR>

What happens if all three are checked? Should that be a radio button and not a checkbox?

Random number between 1-30

What is the REAL problem you are trying to solve by doing this?

#5

And if only two checkboxes are checked? Also obviously you are missing the code to generate random numbers…

#6

If checkbox 1 is checed a random number between 1 - 10 are generated.
If checkbox 2 is checed a random number between 11 - 20 are generated.
If checkbox 3 is checed a random number between 21 - 30 are generated.

Example:
If checkbox 1 & 2 is checed a random number between 1 - 20 are generated.
If checkbox 1 & 3 is checed a random number between 1 - 10 and 21 - 30 are generated.

You don’t seem to understand what I asked. WHY are you doing this? What is the overall task/problem that you need specific sets of random numbers?

I get your question benanamen. Im trying to learn PHP.

#9

then try harder. look at variables and isset here. make a maximum value (which will be 10, 20 or 30) based upon the result (calculated result) of isset analysis.

#10

So you’ve got a nice list that you can compare to the inputs via Set Theory and use that as a key to get a range from a map.

#11

I get learning the language. It’s just this isn’t a very realistic problem to solve. It’s actually easy to handle, but I would recommend a book and working through it, rather than random problems
