title: Mysql database insert with user input variable
body: <p>The below code entered into the database:</p>
  
  <pre><code>"INSERT INTO customer_order (price) VALUES (1)";
  </code></pre>
  
  <p>Instead of <code>VALUES (1)</code>, however, I want the value to be determined by user input.</p>
  
  <p>Like this: </p>
  
  <pre><code>"INSERT INTO customer_order (customer_id) VALUES (".$edit_type.")";
  </code></pre>
  
  <p>This does not work, however, and does not return an error.</p>
