What are common errors or issues when working with radio buttons in PHP forms?

One common issue when working with radio buttons in PHP forms is not properly setting the "name" attribute for each radio button in a group. If the name attribute is not set correctly, the form will not be able to differentiate between the different options selected by the user. To solve this issue, make sure to assign the same name attribute to all radio buttons within a group. 

<form action="submit.php" method="post">
  <input type="radio" name="gender" value="male"> Male
  <input type="radio" name="gender" value="female"> Female
  <input type="radio" name="gender" value="other"> Other
  <input type="submit" value="Submit">
</form>
