Text box dilemma

immodium

Hello all

Im in desperate need of help. I have a form with a text box on it and when i click on submit it outputs what was written in the text box onto the next page. Just wanted to now how, if its possible, to find if a ceratin word had been entered in the text box and can be replaced.

i know its possible to do when there is only 1 word in the text box. Just need to know how to find a word within a sentence and replace that word.

Thankyou

Thanks for the info scoppc.

I have found this code that replaces www.whatever.com into <a href="http://www.whatever.com">www.whatever.com</a>, here is the code:

$link = "/(www[^ ]*)/i";
$link_replace = "<a href=\"http://\1\">\1</a>";

print preg_replace($link, $link_replace, $text_1);

What i would like to know (looks complecated, any websites that explain preg_replace for idiots would be appreciated🙂 )

a)where would i put target= in the code

b)instead of the whatever between the url tags i can have some thing else ther like <a href="http://www.whatever.com">click here</a>

thanks

a)where would i put target= in the code

replace this

$link_replace = "<a href=\"http://\1\">\1</a>";

with this

$link_replace = "<a href=\"http://\1\" target=\"_blank\">\1</a>";
