If statement for nofollow urls with numbers

Trying to block access to tag/386 for eg

[cheaperholidays]

Hello

I wonder if you can help?

We have <?php
if((is_home() && ($paged < 2 )) ¦¦ is_single() ¦¦ is_page() ¦¦ is_category()){
echo '<meta name="robots" content="index,follow" />';

What i would like to to do is noindex, nofollow, all urls with numbers for in folder /tag/386 for eg so that any number following /tag/is blocked

I cannot for the life of me find any php code for greater than

Kind regards

Could you not use robots.txt [robotstxt.org]?

User-Agent: *
Disalow: /tag/

Hey Les,

Far from being expert in PHP and fearing perhaps I miss what you really mean by your question about greater than:

Your snippet is using 'less than' on the variable '$paged', to make this snippet the opposite (and so using 'greater than' in PHP) just exchange the '<' symbol for a '>'. Without writing a lot of script out (*Google: conditional php), you are probably better off with something like;

<?php
if (Con_Index()>0) {
echo WriteMeta("robots","index,follow");
} else {
echo WriteMeta("robots","noindex,nofollow");
}
?>

There will of course be a million ways this can be tackled and probably ten percent of them are worth the time taken to write and test them, I don't blame you for wanting to back your robots.txt file up but if a bot is ignoring robots.txt it is at least a bit unlikely it will honour even 'rel="nofollow"'.

Good luck,
robsoles.

Thanks Rob

I have decided to block robots.txt and leave it at that, you know what its like you think "i wonder is this will work" and of you go on the PHP tangent...

lets see.... you have something like: www.example.com/tag/345/maybe_more/folders/somefile.htm

i am guessing you use htaccess for this?
if so... you urls are being constructed as http://www.example.com/tag/$somevar/$othervar/$pagename.htm

if i am guessing right this far...

if((int)$_GET['somevar']>0)
{
echo '<meta name="robots" content="noindex,nofollow" />';
}

Although robots.txt will not stop bots viewing the page, neither will the robots meta tag. These are just recommendations to the bots to stay away. If you are really bothered about bots not obeying your robots.txt then you could go down the rout of blocking by the UA string. However most of the spam bots use normal UA strings, and its only bots like google, msn, etc that follow robots.txt, so there is not much point in looking at blocking them by UA string.

As far as im aware there are no robots that support the robots.txt file that dont support the meta tags, this also works the other way around. So either method should work, just 2 lines in robots.txt is a lot quicker than a php alternative.

well, if you got to exclude some hundreds of pages, php is prefered.
