addlink script problem

[The_Senator]

I'm working with a script that allows visitors to freely add a link to my site. The problem is I can't seem to get rid of a blank href at the top of the list. Obviously I've screwed up the code somehow, and I was hoping someone here could impart some knowledge on a lowly apprentice. Here's the source for the two relevant files:

link.php:

<?
$file="content/content.txt";
$isopen=fopen($file,"a");
if($isopen)
{
$info=file($file);
$resultcount = count ($info);
$remainder = $resultcount-3;

for($i=$resultcount;$i>=$resultcount-3; $i--)
{
$getline=explode("\t",$info[$i]);
print":. <a href='$getline[0]' target='_blank;'>$getline[1]</a><br>";
}
}
fclose($isopen);
?>
<tr><form action="cgi-bin/addlink.php" method="post" ENCTYPE="multipart/form-data">
<td class="small"><center><input type="text" name="string" size=20 value="http://"></center></td></tr><tr>
<td class="small"><center><input type="text" name="urlname" size=20 maxlength=32 value="site name"></center></td></tr><tr>
<td class="small"><center><input type="submit" name="send" value=" submit "></center></td></tr>
</form>

addlink.php:

<?
$file="content/content.txt";
if (isset($send))
{
$isopen=fopen($file,"a");
if($isopen)
{
fwrite($isopen,"$string \t $urlname \n");
}
fclose($isopen);
}
header("Location: index.shtml");
?>

Do a check for $line[x] to see if it's empty:

<? 
$file="content.txt"; 
$isopen=fopen($file,"a"); 
if($isopen) 
{ 
$info=file($file); 
$resultcount = count ($info); 
$remainder = $resultcount-3; 

for($i=$resultcount;$i>=$resultcount-3; $i--) 
{
$getline=explode("\t",$info[$i]);
if($getline[0] != "") {
print"<a href='$getline[0]' target='_blank;'>$getline[1]</a><br>";
}
} 
} 
fclose($isopen); 
?> 
<tr><form action="addlink.php" method="post"> 
<td class="small"><center><input type="text" name="string" size=20 value="http://"></center></td></tr><tr> 
<td class="small"><center><input type="text" name="urlname" size=20 maxlength=32 value="site name"></center></td></tr><tr> 
<td class="small"><center><input type="submit" name="send" value=" submit "></center></td></tr> 
</form>

Thanks for the reply! I tried that, and I got this message:

Warning: fopen("content.txt", "a") - Permission denied in /home/httpdocs/link.php on line 3

Warning: fclose(): supplied argument is not a valid File-Handle resource in /home/httpdocs/link.php on line 18

Ah, I changed your code because I tested the script locally - you need to correct the path to content-txt: content/content.txt

And also the script-path in the form, if you didn't change it.
