Ok, I have written this script for a Random Quote Generator. What it is suppose to do is this.
Select a quote randomly from quotes.txt file.
Write a quote to the quotes.txt file that you submit.
My code is here:
<?php
function printHeader ()
{
$header = '<html>
<head>
<title>Random Quotes Generator and New Quotes Adder</title>
</head>
<body>
<table cellspacing=1 cellpadding=1 border=1 align="center">';
print($header);
}
function printTrailer ()
{
$trailer = '<tr>
<td>
<center>
<form method="post" action="lab2.php">
<input type="hidden" name="choice" value="generate">
<input type="submit" value="Generate Random Quote">
</form>
<form method="post" action="lab2.php">
<input type="hidden" name="choice" value="add">
<textarea name="uquote" rows=5 cols=60>
Enter your favorite quote here!
</textarea>
<input type="text" name="uauth" size=50 value="Type author name here">
<input type="submit" value="Submit New Quote">
</form>
</center>
</td>
</tr>
</table>
</body>
</html>';
print($trailer);
}
function printQuote ($quote, $author)
{
$quotation = "<tr>
<td>
<center>
$quote$author</center>
</td>
</tr>";
print($quotation);
}
// Get the choice
$choice = $_POST['choice'];
$fileName = "quotes.txt";
printHeader();
if ($choice == "generate")
{
// Read all the lines of the quotation file into an array.
$quotationLines = file ($fileName, FILE_IGNORE_NEW_LINES);
// Each quotation is spread over two contiguous lines in the quotation file - first
// line has the quotation text and second has the author information.
$numQuotes = count($quotationLines) / 2;
// Select a random quote from existing quotations, and display it.
$selected = rand(0, ($numQuotes-1)); // Array indexing starts at 0.
// Ith quotation starts at line 2*I and ends at line 2*I+1 .
printQuote($quotationLines[2*$selected], $quotationLines[2*$selected+1]);
}
else if ($choice == "add")
{
$uquote = $_POST['uquote'];
$uauth = $_POST['uauth'];
// Open the quotation file in append mode
$handle = fopen($fileName, 'a');
fputs($handle, $uquote . "\n");
fputs($handle, "- " . $uauth . "\n");
fclose($handle);
}
printTrailer();
?>
Now I was told that the quotes.txt does not have newline ending for the last line and I needed to Fix it before trying to add new quotes to this file via the script.
What do they mean by not having a newline ending? My quote file consists of the following:
