leere zeile
Hi
wenn ich meine kleine chatfunktion mal so austeste stell ich fest: das, wenn ich im textfeld alle zeilen vollgeschrieben habe und dann ein leeres eingabefeld absende auch "einmal" eine leere zeile hineingeschrieben wird.
was ich nicht will, also soll bei einer absendung mit leeren eingabefeld keine neue zeile hineingeschrieben
werden.
nun weiss ich nicht genau wie ich dieses bewerkstelligen kann.
propiere auch schon ganz schön lange herum!
kann man da vieleicht irgendwie die formularabsendung sperren?
wenn jemand was weiss dann bitte...

propiere auch schon ganz schön lange herum!
und nun hab ichs auch hinbekommen:
function input_to_output()
{
if (!empty($_REQUEST['input']) && !isset($_REQUEST['options'])) {
$textfile = @fopen("text.txt", "a+");
fwrite($textfile, $_REQUEST['nick']. ": ". $_REQUEST['input']. "\r\n");
unset($_REQUEST['input']);
}
else {
$reset = 10;
$textfile = file("text.txt");
unset($textfile[$reset]);
$set = implode($textfile);
$textfile = @fopen("text.txt", "w+");
fwrite($textfile, $set);
echo $_REQUEST['output'];
}
$textfile = file("text.txt");
foreach ($textfile as $line => $_REQUEST['output']) {
if ($line < 9) {
echo $_REQUEST['output'];
continue;
}
else {
$reset = 0;
$textfile = file("text.txt");
unset($textfile[$reset]);
$set = implode($textfile);
$textfile = @fopen("text.txt", "w+");
fwrite($textfile, $set);
echo $_REQUEST['output'];
break;
}
}
}
