PHP or HTML problem?

[halex]

Hello,

I have one row with two columns in my HTML table:

<tr align="left" valign="top">
<td width="70">Comment</td>
<td width="150"><?php print $comment;?></td>
</tr>

The problem is when I print "$comment", and if it is long string, table column will grow in width in order to fit to that string.
I want "$comment" to split into rows and each row to stay within column width of 150 px.

If it has nothing with PHP don't answer.

Thanks

What you can do is:
if($submit) {

1. check the length of the string ($comment).
2. If the string is greater than "n" characters then
   use substr to slice the string
3. then print first half of the string
   print "<tr><td> $first_half </td></tr>
   <tr><td> $second_half </td></tr> ";
   }

hope this works!!

another solution that doesnt need additional rows would be to provide one space after a given number of chars, since the width property of the td tag automatically forces multiple lines (if there are spaces or other chars where a line break may occur)
to be safe, you could also add <br> into the string instead of " ", forcing a linebreak.

the code would look sth like that

$comment = substr( -as many chars as fit-) . "<br>" . substr (......).....

to get the number of chars that fit in 150px, you could either just try some numbers, or, if you want to do it very accurately, you could get the width of each char ("e" has a width of XX px or sth like that), then parse the string char by char and cut when the total length so far is just below 150.

Here is the function:

//$string - what you need to split, $chars - number of chars in row
function format_string($string, $chars) {
$retVal = "";
$length = strlen($string);
if ($length > $chars) {
while ($length - $chars >= 0) {
$retVal .= substr($string,0,$chars);
$retVal .= "<br>";
$string = substr($string,$chars);
$length = strlen($string);
}
$retVal .= $string;
}
else
$retVal = $string;
return $retVal;
}

This is both faster and in situ

<?php

 function repInsert($string, $toInsert, $insertEvery) {
 	$loops = intval(strlen($string) / $insertEvery)-(strlen($string) % $insertEvery == 0 ? 1 : 0);
	for ($i = 0; $i < $loops; $i++) {
    	$string = substr($string, 0, ($i+1)*$insertEvery+($i*strlen($toInsert))).$toInsert.substr($string, ($i+1)*$insertEvery+($i*strlen($toInsert)));
 	}
 	return $string;
 }

 print repInsert("AAABBBCCCDDDEEEFFFGGG", "---Test---", 6);

?>
