Advanced form validation....

Anon

Hi, i am accepting a string input from a textarea. My problem is that if a user sticks in a long unbroken string such as "fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff" my entire page will try to fit it. I need to be able to check within a string to see if any of the words within it are larger than a certain number of chars, and if it is break it at the max point.

Hence if someone enters: "I like to addlotsofcharacterstogethertobeaproblematicchild but I am still friendly" the large word would be broken, and a " " would be added.

Thanks!

Hmmm yeh I ran into this problem in a recent project as well, this is the solution I came up with, it's not totaly pretty, but it works 🙂

//This is a nice little function, just copy and use to your hearts content

<?php
function fixstring($string, $MAX_LEN = 80)
{
$array = explode(" ", $string);

for($i=0;$i<count($array);$i++)
{
if(strlen($array[$i])>$MAX_LEN)
$array[$i] = chunk_split($array[$i], $MAX_LEN, " ");
}

return implode(" ", $array);
}
?>

//This is an example of how to use this code.
<?php
$string = "I like to addlotsofcharacterstogethertobeaproblematicchild but I am still friendly";

//Fix string, max 10 chars per word.
$newstring = fixstring($string, 10);
echo $string."<br>";
echo $newstring;
?>

//This is another example
<?php
$string = "I like to addlotsofcharacterstogethertobeaproblematicchild but I am still friendly";

//Fix string, using defalt value of 80.
$newstring = fixstring($string);
echo $string."<br>";
echo $newstring;
?>

This methood may not be the prettiest, but it works and it's easy to read 🙂
