The Horror Part II: PHP and forms

[Daot Lagorille]

*stumbles in, dirty and bruised*

Am trying to pass values from form to php results page. Works fine, except for the checkboxes:

If I check a box, fine, that value gets passed and database results appear accordingly. HOWEVER:

if checkbox is not checked, no emplty value is passed - nothing. So I don't get any results at all, though I should be getting all records (unrestricted by condition passed if checkbox would have been checked)

I think this may be a foible particular to checkboxes - anyone know away around this?

if you have coded your php script properly and sql correct,then the code should take care of it that if there is not checkboxes selected then fetch all results...to me its a flaw in your program.
However,if you must see some value in the check box fields then thats totally a different story...:D

I ussually do this:

if (!isset($_POST['checkbox']))
{
$value=x;
}
else
{
$value=y;
}

something like this might work a bit better:

if (empty($_POST['checkbox']))
{
$value=x;
}
else
{
$value=y;
}

i believe thats what i used for some radio buttons of mine that were screwing up...

There is an important difference between the two:

isset() will tell you if the variable exists, which empty() will tell you if the variable contains a non-empty or non-zero value. For instance, $var = ""; $var = " "; or $var = "0" are all considered empty...
