str_replace in <textarea>

Copy linkTweet thisAlerts:
Nov 10.2004

Here’s a puzzler:

I have a bunch of text in an array, within a textarea:

[code=php]<textarea><?php echo $row_Stuff[‘blurb’]; ?></textarea>[/code]

that I want to do a str_replace on in order to make certain keywords appear red.

How? Regular HTML obviously doesn’t work in the <textarea> tag…or does it? Is there a way to escape the tags or something?

[code=php]
$keywords = array("one", "two", "three");

echo "<textarea>" . str_replace($keywords, '<font color="red">$keywords</font>', $row_Stuff['blurb']) . "</texarea>n";[/code]

Havent tested it, but should work. ?

[b]Oops, just realised what a silly reply that was. Font tags in a text area. hee hee! Maybe you can modify it using CSS? Sorry. [/b]

@Ben_RogersNov 10.2004 — May I ask why you're using a <textarea>? Is it meant to be modified by the user at all, or do you just want the white space preseved? If so, just use <pre>, and you can use <em>blah</em> with [i]pre em {color: red;}[/i] in your source.

Yessir. Essentially, it is a textfield that contains the default content of an e-mail to be sent. The things to highlight in red are stuff like "Date X, location Y" to make sure that the user remembers to fill them in with meaningful data (data which unfortunately is esoteric enough to not be able to be generated by the database...).

@Ben_RogersNov 10.2004 — Ah. Would it be possible to have this sort of information instead put in through an <input>, so it'd be easier to check if they did in fact input it? (No, you can't make a certain value within a <textarea> look different than the rest of it.)

@Daot_LagorilleauthorNov 11.2004 — Yeah...I thought of that too. Kind of a pain in the ass though, especially because it is there just to make sure that users don't screw up.

One other idea I have tried is to do a str_replace on the text that goes in the textarea, and make the replacement string this:

"rnrn****HEY REPLACE THIS NOW YOU FOOL****rnrn"

but it wasn't well recieved by the users for some reason.
