Could anyone tell me how to (form does post for file editing):
a) Limit the number of bytes written or added.
d) How to add the following date code, to MySQL column :
<input type="hidden" name="RetEdit" value="<?php echo date('Y-m-d', strtotime("+0 days")); ?>">
<?php
// umask to maintain file permissions during next procedure
umask(000);
$filename = $row_Recordset_rs['ReID'].'__r.txt';
$fullfilename=$_SERVER['DOCUMENT_ROOT']."/file3/".$filename;
if (file_exists($fullfilename)) {
if (isset($_POST['submit']) && isset($_POST['contents'])) {
if (is_writable($fullfilename)) {
if ($fp = fopen($fullfilename, 'wb')) {
$bytes = fwrite($fp, $_POST['contents']);
if ($bytes === false) {
echo "Error: could not write to file '{$fullfilename}'";
}
else {
echo "{$bytes} bytes written to file '{$fullfilename}'";
}
fclose($fp);
}
else {
echo "Error: could not open file '{$fullfilename}' for writing";
}
}
else {
echo "Error: file '{$fullfilename}' is not available for writing";
}
}
else {
if (is_readable($fullfilename)) {
echo '<form action= "' . $_SERVER['PHP_SELF'] . '" method="post">'
. '<textarea name="contents" rows="15" cols="80">'
//for PHP 4.3.0 or newer, which this server has
. htmlspecialchars(file_get_contents($fullfilename))
. '</textarea><br />'
. '<input type="submit" name="submit" value="Update Q"></form>' ;
}
else {
echo "Error: could not open file '{$fullfilename}' for reading";
}
}
}
?>
