Maximum characters...

[thesingh]

Hi there,

What i am doing is a bookstore.. when you do a search the information about the books come up with a long desription of it.

What i want to do is give like a preview of the review allowing like 20 characters to be viewed and then the rest of the information will lead on to the next page!

Hope you understood... Thanks for any help in advance!!!!

Use substr($review, 0, 20).

sorry i dont understand???

The function substr takes a string which you want to select a substring of, the starting character where you want to start selecting from, and the number of characters you want to select.

So if your review/description text is called $review, you want to select the first 20 characters, starting from the first character

$preview = substr($review, 0, 20)

im doing some thing wrong here, its just not working with me...

<?php
while($r=mysql_fetch_array($result)){
	$field1 = $r["Author"];
	$field2 = $r["Title"];
	$field3 = $r["Synopsis"];
	$field4 = $r["Price"];

$field3 = substr($field3, 0, 20)

echo "<b>$field1</b><br> $field2</br> $field3 <b>£$field4</b></p>";
}
?>

i need the synopsis to be cut down!!! im just getting an error message for line 48 which is the echo line!!!

Line 48 is where the php parser first encounters an error. This does not neccessarily mean that the error is on this line. It is often on the line before.

You are missing the semi-colon at the end of the $field3 = substr($field3, 0, 20) line
