insert.php

  & lt ;? Php included ("config.php"); If (isset ($ _ POST ['submit'])) {$ name = $ _ POST ["name"]; $ Email = $ _ post ["email"]; $ Phone = $ _ post ["phone"]; $ Budget = $ _ post ["budget"]; $ Insert_query = "Enter the form (name, email, phone, budget) value ('$ name', '$ email', '$ phone', '$ budget')"; $ Thor = mysql_query ($ insert_query); }? & Gt;  

Variables in the dropdown pass option value so that you can change the option value You want to enter the database

  & lt; Id = "budget" name = "budget" & gt; & Lt; Option value = "" & gt; Select & lt; / Options & gt; & Lt; Option value = "0-100" & gt; 0-100 & lt; / Options & gt; & Lt ;! - Value in the first option = "" - & gt; & Lt; Option value = "100-200" & gt; 100-200 & lt; / Options & gt; & Lt; Option value = "200-300" & gt; 200-300 & lt; / Options & gt; & Lt; / Select & gt;
