Preventing blank or already entered values


Posted on 16th Feb 2014 07:03 pm by admin

Im trying to learn how to place a read file line by line and prevent duplicate entries and also BLANK entries, into my process php script,

using feof, I have failed many times and get so many errors such as syntax expecting . or , and so forth
this is my process.php
<?php
$File = "links.txt";
$Handle = fopen($File, 'a');
$Data = "".$_POST['ID'];
fwrite($Handle, $Data."n");
print "Data Addedn";
fclose($Handle);
?>


<?php
countLines("links.txt");
function countLines($filepath)
{
$handle = fopen( $filepath, "r" );
$count = 0;
while( fgets($handle) )
{
$count++;
}
fclose($handle);
return $count;
}

?>
<head>
<meta http-equiv="REFRESH" content="5;test1.php"></HEAD>

please wait... navigating back!



I got fed up and deleted all my work, to start from scratch,

if feof($_POST['ID'])
{
alert 'Already entered';
return;
}
that was just one of my attempts
also im unsure if putting in /n would make it look for /n or new line, if it looks for new line and every file has the new line marker would it always return as the data was already entered?

Thanks in advance for assistance/teaching
