What are some potential pitfalls of using onclick events in each <td> element for form submission in PHP?

Using onclick events in each <td> element for form submission can lead to potential issues such as accessibility problems for users who navigate websites using assistive technologies, as onclick events may not be triggered in the same way. Additionally, it can make the code harder to maintain and debug as the logic is distributed across multiple elements. To solve this issue, it's better to use a single submit button outside of the table to handle the form submission.

&lt;form method=&quot;post&quot; action=&quot;process_form.php&quot;&gt;
  &lt;table&gt;
    &lt;tr&gt;
      &lt;td&gt;&lt;input type=&quot;text&quot; name=&quot;name&quot;&gt;&lt;/td&gt;
      &lt;td&gt;&lt;input type=&quot;email&quot; name=&quot;email&quot;&gt;&lt;/td&gt;
    &lt;/tr&gt;
    &lt;!-- Add more form fields here --&gt;
  &lt;/table&gt;
  &lt;button type=&quot;submit&quot;&gt;Submit&lt;/button&gt;
&lt;/form&gt;
