Why is my mysqli_query() function throwing an

mysqli_query() Error: Insufficient Parameters

The provided PHP code encounters three errors related to the mysqli_query() function. The first error indicates that mysqli_query() expects at least two parameters but received only one. The subsequent errors stem from this initial issue, resulting in invalid parameters for the mysqli_num_rows() function.

Solution:

To resolve the error, the mysqli_query() function must be provided with two parameters: the MySQLi connection handle and the SQL query string. The MySQLi connection handle is established using the mysqli_connect() function, as seen in your code:

<code class="php">$con = mysqli_connect('localhost', 'sagginev_rob', '122989', 'sagginev_Nutrifitness');</code>
Copy after login

Once the connection is established, you can use the mysqli_query() function with the connection handle as the first parameter and the SQL query string as the second parameter:

<code class="php">$search_query = mysqli_query($con, $search_sql);</code>
Copy after login

By providing the correct number of parameters, you can eliminate the errors and execute the SQL query successfully.
