I have a somewhat disturbing problem, I have researched several ways, but found no solution.

Below the explanation:

A very simple system, it looks like a calendar, but within each day of the calendar, there are 3 fields in checkbox to be clicked, in these fields I used the nomenclature of C, A, J (Coffee, Lunch and Dinner) and also made clickable the number of the day.

being as follows:

With this system the Military can schedule the day he will eat in the kitchen.

The problem I’m having is that when it selects more than 1 day number the result appears all duplicated, like this:

Follow the code below:

         $hoje = getdate(strtotime($dates));
         $ultimoDia = cal_days_in_month(CAL_GREGORIAN,

  • Give a print_r($_POST); see what returns to you...

  • The error is in the checkbox forach.. because you are doing two foreach.. so it doubles even :)

  • The problem is that the days have to be associated with the other checkbox

I was able to solve your problem with array two-dimensional, because you need to know which day you choose and you wanted meals associated with that day.

echo "$dia 
<input type='checkbox' name='"; echo "arrachar[$dia][dia]";    echo"' value='$dia'> <center>
<input type='checkbox' name='"; echo "arrachar[$dia][opcaoC]"; echo"' value='C'>C 
<input type='checkbox' name='"; echo "arrachar[$dia][opcaoA]"; echo"' value='A'>A 
<input type='checkbox' name='"; echo "arrachar[$dia][opcaoJ]"; echo"' value='J'>J</td>";

And in the php checkbox.:

if(isset($_POST["arrachar"]))
{
    echo "Você se arranchou para os dias:<BR>";

    foreach($_POST["arrachar"] as $infos)
    {
        if(count($infos)==1) //verifica se tem alguma refeição marcada
                continue;
        $first = 1;
        foreach($infos as $info)
        {
            if($first == 1) //primeiro elemento do array é o dia.
            {
                echo "No dia $info";
                $first = 0;
            }
            else
                echo "e refeição $info";
            echo "<br>";
        }
        echo "<br>";
    }
}

See here the example

Draw up the foreach in this way: The way you did it, it’s duplicated... you can pass a single parameter.

foreach($_POST as $key){
    echo "{$key->dia} - {$key->opcao}";
}

  • I don’t think it works that way...

  • Because every day can have more than one option...

  • Take the test. I usually take the post and put it inside the foreach to fetch the arrays I want, no matter how many are for each day..

  • It has to be with two-dimensional array to associate options with days...

  • Managed to elaborate?
