• PHP – summon a function using buttons

    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.
