input box php

I have a database in mysql
and i use php to access it "LIKE %KeyWord%"
whitch is fine but i to enter the KeyWord in a Box on a webpage
ether one or more words

You can try this:

// the name of field on the form must be keywords, or you
// can change the code to fit the name at your form
$keywords = split(" ",$keywords);
$sql = "SELECT * FROM table WHERE";
for($i = 0; $i < sizeof($keywords); $i++) {
if($i == 0) {
$sql_tmp = " field_name LIKE '%" . $keywords[$i] . "%'";
} else {
$sql_tmp = " AND field_name LIKE '%" . $keywords[$i] . "'";
}
$sql .= $sql_tmp;
}
$sql .= " ORDER BY field_name";

Hope this helps...
