keep yes or no selection?

[garyed]

Is there a simple way to keep a yes or no selection in a drop down menu after the page is submitted?

<form name="survey" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
Satisfied<select name="satisfied">
<option value="yes"> yes </option>
<option value="no"> no </option>
</select>
<input name="submit" type="submit" value="Submit">
</form>

You could do something like:

 

...

<select name="satisfied">
<option value="yes"<?php if($_POST['satisfied'] == 'yes') { echo ' selected="selected"'; } ?>> yes </option>
<option value="no"<?php if($_POST['satisfied'] == 'no') { echo ' selected="selected"'; } ?>> no </option>
</select>

...

 

 

Also, you should avoid using $_SERVER['PHP_SELF'] in forms for security reasons. For more info, see:

Or, may be like this:

<form name="survey" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
Satisfied<select name="satisfied">
<?php
$satisfied_options = array("yes", "no");
$satisfied_opted = '';
foreach($satisfied_options as &$option) {
  if ( isset($_POST['satisfied']) ) {
    $satisfied_opted = ($_POST['satisfied'] == $option ) ? 'selected' : '';
  }
  echo '<option value="'.$option.'" ' . $satisfied_opted . '>'.$option.'</option>';
}
?>
</select>
<input name="submit" type="submit" value="Submit">
</form>

Thanks guys , that worked fine.

Instead of using echo $_SERVER['PHP_SELF'] is it OK to just use the url of the same page the form is on?

You can leave the action attribute empty to submit the form in the same page. It is completely valid XHTML and also included in the form submission algorithm of HTML5 (look here, point 9).
