Fatal error: Call to undefined function mysqli_result()

database, database-connection, mysql, mysqli, php

Solution

Don't use this kind of code. It's highly inefficient. Use `mysqli_fetch_assoc()` instead:

while($row = mysqli_fetch_assoc($result)) {
   $id = $row['ID'];
   $name = $row['name']; 
   etc..
}

One SINGLE database operation, rather than the 3+ you're trying to do.

Problem

Can someone please tell me why this doesnt work, when I tried to switch my old sql to sqli: ``` $query = "SELECT * FROM `product_category`"; $result = mysql_query($query, $connect) or die("could not perform query: " . mysql_error()); $num_rows = mysql_num_rows($result); for ($i=0; $i < $num_rows; $i++) { $ID = mysql_result($result,$i,"ID"); $name = mysql_result($result,$i,"name"); $description = mysql_result($result,$i,"description"); ``` to: ``` $query = ("SELECT * FROM `product_category`"); $result = mysqli_query($connect, $query) or die("could not perform query"); $num_rows = mysqli_num_rows($result); for ($i=0; $i < $num_rows; $i++) { $ID = mysqli_result($result, "ID"); $name = mysqli_result($result,$i,"name"); $description = mysqli_result($result,$i,"description");` ``` it keeps giving me an error of: "Fatal error: Call to undefined function mysqli_result()"
