empty array value for if condition

[Anon]

hi,

for a multiple file upload i wanna force the user to fill all field values.

on the target page i wanna check if all fields are filled - if not print out a error message.

i tried

if (!count($picture)) {}
if (sizeof($picture) == "0" ) {}
if (sizeof($picture) == '0' ) {}

but none of these condition works for me - it goes always to the else part although the array field is empty

the fields are generated with a loop

    for ($i=0; $i<$Files; $i++){
?>
<p> 
      <input type="file" name="picture[]" size="20">
      <font face="Arial, Helvetica, sans-serif" size="2">Name</font>
      <input type="text" name="filename[]">
    </p>
<?	
}
    ?> 

the best way would be to do it clientside - but JS doens't accept [] in a condition...

would be apprecheated for help

regards,
christian

Hi,

Have you tried

If(empty($myVar)) {
echo "Is empty";
} Else {
echo "Is not empty";
}

??

If you're a nifty js programmer it's probably easier to do in js as you won't have to submit the form first, however, if your js is anything like mine it'll take a week to get it cross-browser compatible 🙂
