title: Add custom plugin to just one page in wordpress
body: <p>I am really new to wordpress and want to add a plugin I created to a page I have added in wordpress. </p>
  
  <p>The page I have added is called "booking" and all it contains at the moment is the header and footer. </p>
  
  <p>The plugin is a folder which will return a booking process. </p>
  
  <p>In the php file I have the following:</p>
  
  <pre><code>function sc_booking_process() {
      if ( is_page( 'booking' ) ) {
          add_action( 'wp_enqueue_scripts', 'include_regForm_validation' );
      }
  
  
      return '&lt;div id="choices"&gt;
      &lt;h2&gt;Ticket Purchase&lt;/h2&gt;
      &lt;h3&gt; Select Ticket Types&lt;/h3&gt;
     &lt;form id="form1" action="" method="post" onsubmit="return calcTotal(this)"&gt;
        &lt;table id="tickets" style="float:left"&gt;
          &lt;thead&gt;
              &lt;th&gt;Ticket Type&lt;/th&gt;
              &lt;th&gt;Price&lt;/th&gt;
              &lt;th class="Quantity"&gt;Quantity&lt;/th&gt;
          &lt;/thead&gt;
       &lt;tbody&gt;
          &lt;tr&gt;
              &lt;td&gt;Adult &lt;span class = "small-text"&gt;18 +&lt;/span&gt;&lt;/td&gt;
              &lt;td&gt;&amp;#128;10.00&lt;/td&gt;
              &lt;td class="Quantity"&gt;
                  &lt;select name="select1"&gt;
                  &lt;option value="0"&gt;0&lt;/option&gt;
                  &lt;option value="10"&gt;1&lt;/option&gt;
                  &lt;option value="20"&gt;2&lt;/option&gt;
                   &lt;option value="30"&gt;3&lt;/option&gt;
                  &lt;/select&gt;
              &lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td&gt;Child &lt;span class = "small-text"&gt;12 years and under&lt;/span&gt;&lt;/td&gt;
              &lt;td&gt;&amp;#128;6.00&lt;/td&gt;
              &lt;td class="Quantity"&gt;
                  &lt;select name="select1"&gt;
                      &lt;option value="0"&gt;0&lt;/option&gt;
                      &lt;option value="6"&gt;1&lt;/option&gt;
                      &lt;option value="12"&gt;2&lt;/option&gt;
                      &lt;option value="18"&gt;3&lt;/option&gt;
                  &lt;/select&gt;
              &lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td&gt;Teen &lt;span class = "small-text"&gt;13 - 17 years&lt;/span&gt;&lt;/td&gt;
              &lt;td&gt;&amp;#128;7.00&lt;/td&gt;
              &lt;td class="Quantity"&gt;
                  &lt;select name="select1"&gt;
                      &lt;option value="0"&gt;0&lt;/option&gt;
                      &lt;option value="7"&gt;1&lt;/option&gt;
                      &lt;option value="14"&gt;2&lt;/option&gt;
                      &lt;option value="21"&gt;3&lt;/option&gt;
                  &lt;/select&gt;
              &lt;/td&gt;
          &lt;/tr&gt;
              &lt;td&gt;&lt;input name="" type="submit" value="Proceed" onclick = "hide()"/&gt;&lt;/td&gt;
          &lt;/tbody&gt;
          &lt;/table&gt;
      &lt;/form&gt;
  }```
  I assume the add_action is done wrong as I'm not sure what function I should have instead of wp_enqueue_scripts.
  
  Any advice on how to fix this would be really appreciated. Thanks!
