limiting field extraction to 40 characters

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am using

<? $result = mysql_query("SELECT * FROM courses",$db);
printf("<select name=\"coursecode\">\n");
while ($myrow = mysql_fetch_array($result)) {

$l=$myrow['coursecode'];
?><option value="<?=$l;?>"<?=($_POST['coursecode']==$l)?'
selected="selected"':"";?>><?=$myrow['title'];?></option><?
}
printf("</select>\n");
?>

to generate a html <option><select>. Unfortunately a few of my course titles
are really long and this effects the rendering of the <option><select>
making it ultra wide.

Is there a way i can print only the first 40 characters of the title - even
though the full title lives in the db still (it is used throughout the
site)?

cheers
