hi,
i got problem in wordwrap tetxarea
this textarea fetching from database

PHP Code:


$query = "SELECT text FROM t_emp ";
$result = mysql_query($query) or die("Query failed: Fetch all rows");

//textarea in form

Code:

<TABLE BORDER=1 CELLSPACING=0 CELLPADDING=1 width=100% name="rsTable" id=rsTable cols=11>    
<td  align="center">
 <textarea name="text" style="width:100px:" class="mybar" id="tar" cols="20" rows="1" onfocus="tarea();" onblur="tarea();" title=""></textarea>
</td>

PHP Code:


<? while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {
$output = wordwrap($line['text'], 15,"\n", 1);?>
//printing in form
<td align="center"><div style="width:100px:"><?echo "$output\n";?></div></td>

let say i type some text in textarea
$text = "The quick brown fox jumped over the lazy dog.";

but as result im not getting any change it prints the whole line no wordwrap is working is there error in table width=100% and textarea width=100px as i m having 11 cols in form and i used px only in textarea is this is right way
whast the diff. between px and %

i want something like example2 in the link
www.php.net

<tr bgcolor="#cccccc">
<th nowrap>Datum</th>
<th nowrap>Von</th>
<th nowrap>Bis</th>

OK, ignoring your code, I quickly wrote a sample PHP page that I think, will help you figure out your issue with wordwrap and a fixed (sized) textarea. If my assumption is wrong please let me know.

Copy and save the following php 'script' to, let's say test.php:

PHP Code:


<?php
// FILENAME: test.php
// ------------------
// save this file as 'test.php' and view the page with your favourite browser
// to see if the text area works like you want it to.

// sample text for the textarea.
$text = 'Aaaaaaaaaaaaargh! The quick brown fox jumped over the lazy dogs... again!';

// let's wrap any word longer than 9 characters in the textarea!
$text = wordwrap( $text, 9, "\\n", 1 );
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Textarea Example</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
</head>
<body>
<!-- imagine the table taking up the entire width of the reader's screen
  iow, 100% width -->
<table border="1" style="width:100%" cols="3">
  <tr>
    <!-- with 3 main columns -->
    <th>Column 1</th>
    <th>Column 2</th>
    <th>Column 3</th>
  </tr>
  <tr>
    <td style="vertical-align:top">A cell in Column 1</td>
    <!-- We add a simple form with a textarea here -->
    <td style="vertical-align:top; text-align:center;">
      <form>
        <!-- the textarea size is controlled by the style attribute; i.e.
            width:100px; and height:100px -->
        <textarea name="sample" id="sample" style="width:100px; height:100px;" cols="9"><?php echo $text; ?></textarea>
      </form>
    </td>
    <td style="vertical-align:top">A cell in Column 3</td>
  </tr>
</table>
</body>
</html>

The difference between % and pixels (px) values are % will take the size (width or height) off the containing element. In other words, if the available screen width is 500px, an attribute width="100%" will make that element have a width of 500px, (which is 100% off 500px)..
