simple PHP coding needed!

[bluemicrobyte]

So I also need a simple script that will contain the following 2 parts:


a simple html form with two fields - one for a url and one for a line of text. And a submit button. When submitted, it will add the URL and line of text to the top of a .txt file (or MySQL database if needed, but preferably .txt).

The second part is a php script that reads the text file with the data and outputs html code in the following format (or similar):



<a href="NEWEST URL" class="weblinks"> NEWEST LINE OF TEXT </a>

<br>

<a href="SECOND URL" class="weblinks"> SECOND LINE OF TEXT </a>

<br>

etc until X items have been listed - probably around 5

I'd also like another php file which lists every item in the log file for archival purposes.

The two parts are separate - the form is for me (and only me, don't worry about security issues) to add links to my webwatch box (http://www.microbyteproductions.com/home.php) on the home page. The second part is to display the latest links in that webwatch box on the home page.

Help with this is greatly appreciated!

Make sure the file exists before you run either script, the code doesn't check for it. Just create an empty file called links.txt. If you want to use a different file name change the $file variable in both scripts. Make sure to change the form action on write.php if you rename it.

read.php

<?
$file = "links.txt";

$fh = fopen($file, 'r');

// read first record
$line = fgets($fh);

while(!feof($fh))
{

// get rid of Windows line breaks
$line = str_replace("\r\n", "", $line);

// get rid of Unix line breaks
$line = str_replace("\r", "", $line);

$split = strpos($line, " ");
$link = substr($line, 0, $split);
$title = substr($line, $split + 1);

echo "<a href=\"$link\">$title</a>\n";
echo "<br />";
// read next record
$line = fgets($fh);
}
fclose($fh);
?>

write.php

<?
$file = "links.txt";

// read and store the old links file
if(strlen($_POST['title']) > 0 && strlen($_POST['link']) > 0)
{
$lines = array();
$i = 0;

$fh = fopen($file, "r");
$line = fgets($fh);
while(!feof($fh))
{
$lines[$i] = $line;
$line = fgets($fh);
$i++;
}
fclose($fh);

$fh = fopen($file, "w");
$safelink = str_replace(" ", "%20", $_POST['link']);
fwrite($fh, $safelink . " " . $_POST['title'] . "\r\n");
for($j = 0; $j < $i; $j++)
fwrite($fh, $lines[$j]);
fclose($fh);
}
?>
<form action="write.php" method="post">
Title:
<input type="text" name="title" />
<br />
URL:
<input type="text" name="link" />
<br />
<input type="submit" />
</form>


And here's the logger.

logger.php
<?
$file = "links.txt";
$fh = fopen($file, "r");
$line = fgets($fh);
while(!feof($fh))
{
echo $line;
$line = fgets($fh);
}
fclose($fh);
?>

Huzzah! Hail TimP!

Would it be possible to change read.php so that it only displays the most recent x items? I'd prefer that the value be changable but if it isn't then 5 is a good number.

[TimP]

<?
$file = "links.txt";
$display = 5;
$fh = fopen($file, 'r');

// read first record
$line = fgets($fh);
$i = 0;
while(!feof($fh) && $i < $display)
{

// get rid of Windows line breaks
$line = str_replace("\r\n", "", $line);

// get rid of Unix line breaks
$line = str_replace("\r", "", $line);

$split = strpos($line, " ");
$link = substr($line, 0, $split);
$title = substr($line, $split + 1);

echo "<a href=\"$link\">$title</a>\n";
echo "<br />";
// read next record
$line = fgets($fh);
$i++;
}
fclose($fh);
?>
