How can you ensure that an input field remains empty and an option remains selected upon page reload in PHP?

To ensure that an input field remains empty and an option remains selected upon page reload in PHP, you can use the ternary operator to check if the form has been submitted. If it has not been submitted, you can set the input field value and selected option accordingly. If it has been submitted, you can use the $_POST superglobal to retrieve the submitted values.

&lt;input type=&quot;text&quot; name=&quot;input_field&quot; value=&quot;&lt;?php echo isset($_POST[&#039;input_field&#039;]) ? $_POST[&#039;input_field&#039;] : &#039;&#039;; ?&gt;&quot; /&gt;
&lt;select name=&quot;select_field&quot;&gt;
    &lt;option value=&quot;option1&quot; &lt;?php echo (isset($_POST[&#039;select_field&#039;]) &amp;&amp; $_POST[&#039;select_field&#039;] == &#039;option1&#039;) ? &#039;selected&#039; : &#039;&#039;; ?&gt;&gt;Option 1&lt;/option&gt;
    &lt;option value=&quot;option2&quot; &lt;?php echo (isset($_POST[&#039;select_field&#039;]) &amp;&amp; $_POST[&#039;select_field&#039;] == &#039;option2&#039;) ? &#039;selected&#039; : &#039;&#039;; ?&gt;&gt;Option 2&lt;/option&gt;
&lt;/select&gt;
