• PHP – summon a function using buttons

    Nina Member

    I’ve a bit of a problem with PHP and the interwebs is full of contradicting information.
    Basically, I want to summon a function that uses the values using a html button. I’ve found that you can have your server listening to a form with some buttons in it, but it still won’t work…
    Here’s my function:

    
    function FillOutArray()
    {
    if(isset($_POST['submit']))
    {
    $array[counter] = $_POST['random'];
    $counter+=1;
    }
    else // resetting array
    {
    $counter = 0;
    $array = array();
    }
    }
    

    and here’s my form:

    you put that php code as a function but you never actually call that function. Unless there is more code you did`t post here. Try this:

    if(isset($_POST['submit']))
    {
    $array[counter] = $_POST['random'];
    $counter+=1;
    }
    else // resetting array
    {
    $counter = 0;
    $array = array();
    }
    

    And make sure you clean anything that comes from user input. Although I have no clue what you will do with the data from the input, but it`s best to get the habit of closing security issues right away.

    Also… Input type “textbox”? O_o
    Use a text type or a textarea if you were aiming for a “textbox” and not a field.
