title: Handling data from select option form in PHP
body: <p>I have basic login form :</p>
  
  <pre><code>....
   &lt;input type="text" required autocomplete="off" name="user_name"/&gt;
   &lt;input type="password" required autocomplete="off" name="password"/&gt;
   ....
  </code></pre>
  
  <p>But I want user choose username from section option instead of input username from keyboard. So I make a select option form</p>
  
  <pre><code>                     &lt;div class="col-md-2"&gt;
  
                      &lt;select name="Grade" id="Grade"   
                      data-live-search="true" class="chosen selectpicker form-control" required&gt;
                      &lt;option value=""&gt;Select Grade&lt;/option&gt;
  
                      &lt;/select&gt;
                      &lt;/div&gt;
                      &lt;div class="col-md-1 col-sm-12" id="lable1"&gt;&lt;id="lable1"&gt;user&lt;/div&gt;
                      &lt;div class="col-md-2"&gt;
                         &lt;!--select username--&gt;
                      &lt;select class="selectpicker form-control" name="user" id="user"  autofocus="autofocus" required&gt;
                          &lt;option value=""&gt;Select an Option&lt;/option&gt;                            
                      &lt;/select&gt;
                    &lt;!--select username--&gt;   
                      &lt;/div&gt;
  </code></pre>
  
  <p>How can I hanlde data from select option form instead of input username to</p>
  
  <pre><code>&lt;input type="text" required autocomplete="off" name="user_name"/&gt;
  </code></pre>
