Göra text bold, till länkar osv...

Så som de va här på whoa innan, man kan även skriva (b)BOLD(/b)

replace("(b)", "<font face="bold">")

;C

fast replace får du ju byta ut mot lämplig funktion, men det e väl det enklaste =)

alltså, det är php sidan är i, så, men kan du förklara mer utförligt ?

jamen, när texten postas så går den genom ett script som letar igenom texten efter en viss sträng och byter ut den mot en annan,

tex "(B)" -> <font face="bold"> text fram tills (/B).... "(/B)" -> </font> osv..

borde väl gå fint?

hmm <b> räcker väl antar jag iofs..

skriv hela scriptet som det skall vara så får ja se

e de typ

<javascript>
replace("(b)", "<b>")
replace("(/b)", "</b>")
</script>

eller e de ?

<?
replace("(b)", "<b>")
replace("(/b)", "</b>")
?>

ingen aning, du får la göra nått själv =)

<html>
<body>

<script type="text/javascript">

var txt="Hello World!"

document.write("<p>Big: " + txt.big() + "</p>")
document.write("<p>Small: " + txt.small() + "</p>")

document.write("<p>Bold: " + txt.bold() + "</p>")
document.write("<p>Italic: " + txt.italics() + "</p>")

document.write("<p>Blink: " + txt.blink() + " (does not work in IE)</p>")
document.write("<p>Fixed: " + txt.fixed() + "</p>")
document.write("<p>Strike: " + txt.strike() + "</p>")

document.write("<p>Fontcolor: " + txt.fontcolor("Red") + "</p>")
document.write("<p>Fontsize: " + txt.fontsize(16) + "</p>")

document.write("<p>Lowercase: " + txt.toLowerCase() + "</p>")
document.write("<p>Uppercase: " + txt.toUpperCase() + "</p>")

document.write("<p>Subscript: " + txt.sub() + "</p>")
document.write("<p>Superscript: " + txt.sup() + "</p>")

document.write("<p>Link: " + txt.link("http://www.w3schools.com") + "</p>")
</script>

Det är ett Nyhetsscript i PHP
Du måste lägga in lösenord på 3 ställen, det är dem som är märkta i bold.
Du måste också skapa en txt fil som ligger i samma mapp som skall heta news.txt
