[SOLVED] need a line break after a certain amount of characters...

<?php

$connect = mysql_connect("localhost", "root", "") or die(mysql_error());
mysql_select_db("blog", $connect) or die(mysql_error());

echo "<hr />";

echo "Are you an admin? <a href='index.php?p=blog&p=credentials'>Place a post</a>";

?>

 

I figured that it would be one of these two pages of code. I want to have a line break after 100 characters. I've tried...

 

<?php

$connect = mysql_connect("localhost", "root", "") or die(mysql_error());
mysql_select_db("blog", $connect) or die(mysql_error());

if(!$_POST['submit']){
echo "

<form action='index.php?p=blog&p=admin' method='POST'>

<table width='100%'>

<tr>

<td>
Title:
</td>

<td>
<input type='text' name='title' maxlength='32' />
</td>

</tr>

<tr>

<td width='9%' valign='top'>
Your Name:
</td>

<td valign='top'>
<input type='text' name='name' maxlength='32' />
</td>

</tr>

<tr>

<td valign='top'>
Your Email:
</td>

<td>
<input type='text' name='email' maxlength='35' />
</td>

</tr>

<tr>

<td valign='top'>
Your Post:
</td>

<td>
<textarea cols='50' rows='5' name='message' maxlength='250'></textarea>
<p><input type='submit' name='submit' value='Post' />
</td>

</tr>
</table>

</form>";
}else{

$title = $_POST['title'];
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$date = date("Y-m-d");
    $time = date("H:i:s");

if($name && $email && $message){
	$querypost = mysql_query("INSERT INTO blog VALUES('','" . $title . "','" . $name . "','" . $email . "','" . $message . "','" . $time . "','" . $date . "')");

	if(strlen($message) < 50){
		$querypost.= mysql_query("INSERT INTO blog VALUES('','" . $title . "','" . $name . "','" . $email . "','" . $message + "<br />" . "','" . $time . "','" . $date . "')");
	}  

	echo "<hr />Please wait... <meta http-equiv='refresh' content='2'>\n";
	echo "Successfuly posted!";
}
}

?>

 

But this didn't seem to work. Could someone please help me.

Apply wordwrap to the string you want... wrapped.

[Noskiw]

I applied wordwrap like you said, but to put it in short terms, there was no effect what so ever.

 

<?php

$connect = mysql_connect("localhost", "root", "") or die(mysql_error());
mysql_select_db("blog", $connect) or die(mysql_error());

function bbcode($string)
{


    if ($string) {


        $bbcode_array = array('[b]', '[/b]', '[u]', '[/u]', '[i]', '[/i]', '[code]',
            '

', '', '');

 

 

        $bbcode_array_2 = array('<b>', '</b>', '<u>', '</u>', '<i>', '</i>',

            '<center><div style="width:90%;padding:3px;background-color:#000099;color:#FFFFFF;border:2px solid;">',

            '</div></center>', '<img src="', '">', '<img src="http://localhost/images/P.png" width="30" height="30" />');

 

 

        $new_string_2 = str_ireplace($bbcode_array, $bbcode_array_2, $string);

 

 

        return $new_string_2;

 

 

    }

}

 

echo "<h1>Blog</h1>";

 

$query = mysql_query("SELECT * FROM blog");

 

if (mysql_num_rows($query) == 0) {

    echo "<hr />There are no posts yet, make the first in the admin section!";

} else {

    while ($row = mysql_fetch_assoc($query)) {

    echo "<hr />";

    $title2 = $row['title'];

    $name = $row['name'];

    $email = $row['email'];

        $post = $row['post'];

        $date = $row['date'];

        $time = $row['time'];       

           

$text = $post; 

        $new = wordwrap($text, 50, "<br />", true);

               

        echo "<h3>Title: " . $title2 . "</h3><table width='100%'><tr><td><b>Posted by: " . $name . "(" . $email . ") at " . $time . " on " . $date . "</b></td></tr><tr><td>" . nl2br(bbcode(strip_tags($new . "<br />"))) . "</td></tr></table>\n";       

    }

}

 

echo "<hr />";

 

echo "Are you an admin? <a href='index.php?p=blog&p=credentials'>Place a post</a>";

 

?>[/code]

try:

 

wordwrap(nl2br(bbcode(strip_tags($post))), 70, '<br />')

 

where 70 is whatever number of characters to display 'til the wrap.

[Noskiw]

Unfortunately, no effect again. I'm beginning to give up on php. Even the smallest of projects, I take them too far, when all I want to do is to succeed...

[Noskiw]

Nevermind. Thank you so much. This is something i have been struggling with for quite a while now. I had to make an extra comma "," and put "true" there without the quotation marks. I read the php.net manual. It turns out that it can be very useful after all... Thank you. If there was good rep in this forum, i would give you thousands of it.

[mrMarcus]

change this:

 

nl2br(bbcode(strip_tags($new . "<br />")))

 

to:

 

wordwrap(nl2br(bbcode(strip_tags($post))), 70, '<br />', true)

 

lose these two lines:

 

$text = $post;   
$new = wordwrap($text, 50, "<br />", true);

[Mchl]

nl2br(wordwrap()) not wordwrap(nl2br())

 

wordwrap adds newlines (\n\r) and nl2br replaces them with < br/> tags. If you do nl2br before wordwrap, you will not see any effect.

 

[edit]

 

Oh... @mrMarcus  you're specyfing the newline in wordwrap itself. So nl2br should not be necessary at all.

[mrMarcus]

Oh... @mrMarcus  you're specyfing the newline in wordwrap itself. So nl2br should not be necessary at all.

nl2br() would still be necessary to maintain integrity of the original post i would believe.  otherwise, the \n's that are created within a textarea or drawn from the db would not be converted to proper line-breaks (<br />) for normal display on a page.

 

normally speaking, you are correct in that most cases wordwrap() and nl2br() are not needed together.
