[Gruzin]

Hope u guys can help me, I've got a problem:
I've got a form where I input some text, but I cann't make a space between lines (kind of paragraph); please help me, I really need this  :'(

Here is the code:

<?php
$link = "admin.php";
$linkShow = "Your info is saved";
$text = stripslashes($_POST["text"]);
$text_file = "text/homepage.txt";
$name_gax = file($text_file); //opens with array
$text_open = fopen($text_file, "w+"); //open message file with write
fputs($text_open, $text);
fclose($text_open);
echo "<a href='".$link."'>".$linkShow;
?>

this any good?

[code]$text = stripslashes (preg_replace(array("/\r?\n\r?\n/","/\r\n/"),array("</p>\n\n<p>","<br />\n"),$_POST['text']));[/code]

[Gruzin]

thanks man :) can u explain me how does it work?

[ozPATT]

if only i could!

haha, it is a piece of code that I acquired some time ago, and uses regular expressions. Basically, it replaces any line returns from the textarea, with the paragraph and break tags that html uses.

eg

\r\n is one line break or return. so that should be <br />. two of them, equal a paragraph, which is <p></p>.

Pretty clever really. Did it do what you wanted?

Why not just use nl2br()? Alot simpler. Does the samething.

nl2br converts any newline characters (\r\n, \r, \n) to < br /> (without the space before the br).

ye I've done it! you"ve saved me ozPATT, cheers mate:)

[ozPATT]

is that a predefined function? never heard of it.

glad to help Gruzin

[wildteen88]

nl2br has been around since PHP3. Check it out [url=http://uk2.php.net/manual/en/function.nl2br.php]here[/url]

[Gruzin]

wildteen88  do u mean something like this?

$text = stripslashes (nl2br($_POST['text']));

it doesn't work......

[kenrbnsn]

[quote]it doesn't work[/quote]
covers a lot of ground. What doesn't work? What did you expect?

I would do the functions is this order:
[code]<?php $text = nl2br(stripslashes($_POST['text'])); ?>[/code]

[wildteen88]

remove stripslashes.

[Gruzin]

it works, why remove srtipslashes?

Thanks guys:)

[wildteen88]

Beacuase it intefere with nl2br and the whitepace characters (\n, \r, etc).

[kenrbnsn]

That's why I suggested to reverse the order of the functions.

ok, another question if I won't distrub you:

when I input the text and need to write bold text or link it, how can I do that?
Thanks

[kenrbnsn]

You need to output the correct HTML tags along with the text.

For bolding:
(the old way)
[code]<?php echo '<b>' . $text . '</b>'; ?>[/code]
(the new way)
[code]<?php echo '<span style="font-weight:bold">' . $text . '</span>'; ?>[/code]

To create a link:
[code]<?php echo '<a href="http://url.goes.here/">' . $text . '</a>'; ?>[/code]

[Gruzin]

how can I make a form like in this forum, when u click a button text becomes bold or u make it linked?

[Gruzin]

somebody please help:(

[wildteen88]

This is called BBCode. Search google for BBCode Inserter or something like that. It requires javascript. But to replace the BBCodes ie [ b]hello[/b] in to [b]hello[/b] will require the use of regular expressions. [url=http://www.phpfreaks.com/forums/index.php/topic,101566.msg402102.html#msg402102]Here[/url] is a very basic BBCode Parser, it parses bold, italic and underline BBCode.

thanks, I'll try that:)
