I'm trying to build a query using php and mysql,
$query = "select * from products where product_name = '$item_name'";
this works when $item_name holds only one name, but $item_name is an array and based on the user's interaction can contain multiple names, how can I make the query to run for multiple name and get the resulted rows.
Thanks in advance
Here's how you could build a safe list of names for inserting into an IN clause...
if (is_array($names) && count($names))
{
$filter="('".implode("','" array_map('mysql_real_escape_string', $names))."')";
$sql="select * from products where product_name in $filter";
//go fetch the results
}
else
{
//input was empty or not an array - you might want to throw an
//an error, or show 'no results'
}
array_map returns the input array of names after running each name through mysql_real_escape_string to sanitize it. We implode that array to make a nice list to use with an IN clause.
You should always ensure any data, particularly coming directly from the client side, is properly escaped in a query to prevent SQL injection attacks.
else clause to avoid surprises ;-)$vals = implode(',',$item_name);
$query = "select * from products where product_name in (".$vals.");";
Give that a try.
$item_name? If it's, for instance, comma-separated list, you may want to explode it first. But go for Paul's reply.$query = "select * from products where product_name in(";
foreach($item_name as $name)
{
$query .= "'" . $item_name . "', ";
}
$query = substr($query, 0, strlen$query) - 2);
$query .= ");";
First answer (by inkedmn) is really the best one though
foreach($item_name as $name) {
$query = "select * from products where product_name = '$name'";
//whatever you want to do with the query here
}
something like that ought to do it.
Based on inkedmn's response (which didn't quote the item names):
$query = 'select * from products where product_name in ("' . implode('", "', $item_name ) . '")';
Although you may be better with a fulltext search.
