<?php

$text = nl2br($text);

$table = 'news'; 
$sql   = "INSERT INTO $table(title, text)VALUES('$title', '$text')";
$result= mysql_query($sql);

Kan noen av dere fortelle meg hvordan eller gjøre om dette scriptet slik at når du trykker på Submit så sjekker den først om alle felt er utfylte.

 

Så vis et eller to ikke var utfylt skal d vises slik:

 

There was a couple of errors:

 

-- Please enter a title

-- Please enter your text

 

Vis det var en database error skal det komme

 

There was an error!

 

Viss alt gikk greit utfør dette:

 

echo '<br /><strong>Successful</strong>';

echo '<meta http-equiv="refresh" content="2;url=news_add.php" />';

 

Noe som kan hjelpe?

 

TAKK!
