preg_replace and metatags...

[paul brown]

howdy,

I have some text:

This is {search}Pam Grier{/search}.

What I want is this:

This is <a href="somepage. php?keyword=Pam Grier">Pam Grier</a>.

I am having a hard time figuring out a regex to do this using
preg_replace or ereg_replace.

Could someone offer me a bit of assistance, please?

Thanks in advance,

Paul Brown

You could use strpos to find where {search} and {/search} are.
And then with substr filter Pam Grier out.

Looking up wich of the signs in {/search} that have to be escaped, and
then matching {search}(.*?){/search} would put Pam Grier in $1

Try this:

<?php
$txt0 = 'This is {search}Pam Grier{/search}.';

$txt1 = preg_replace('/(.*){search}(.* ){\/search}(.*)/i',
## $1 $2 $3
'$1<a href="somepage. php?keyword=$2" >$2</a>$3', $txt0);

$txt2 = preg_replace('/(.*){search}(.* ){\/search}(.*)/ie',
## evaluate replacement ^
'\'$1<a href="somepage. php?keyword=\' . urlencode(\'$2\ ') . \'">$2</a>$3\'',
$txt0);

echo "txt0 = $txt0\ntxt1 = $txt1\ntxt2 = $txt2\n\n";
?>

This should work for you:

<?php
preg_match_all( '`(\{search\})( .*)(\{/search\})`iU',$ string,$matches );
$search=$matche s[0][0];
$term=$matches[2][0];
$string=str_rep lace($search,'< a href="somepage. php?keyword='.
urlencode($term ).'">'.$term.' </a>',$string);
?>

Also, it will take into account the formatting for the search term in
the URL.

I like that comment style! A very good idea with complicated
preg_replaces. Thanks!

What about extended syntax? I like it even more that that one :)


$txt1 = preg_replace(
'/ # start of regular expression
(.*) # = $1 in replacement string
{search} # literal "search" enclosed in braces
(.*) # = $2
{\/search} # literal "{/search}"
(.*) # = $3
/ix', # end regexp, case insensitive, extended syntax

'$1<a href="somepage. php?keyword=$2" >$2</a>$3', $txt0);
