Using "value = <?print $listbox; ?>" on forms?

Hey Guys,

 

You know when you submit a form on the same page and you display a list of errors back to the user . . please fill username etc.

 

You then use value="<?print $firstname; ?>" and so on to fill in the fields that the user has already entered correctly so they dont have to fill that part in again.

 

Just want to know how you do it for list boxes because when you use value="<?print $category; ?>" for a listbox it doesnt seem to work.

<select name="listbox" size=20>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select>

 

It is because a list box is setup differently. You would have to format the $category and have each option laid out like above.

Here's how I do it:

 

<select name="state">

<?php

$user_state = $_POST['state'];

$state_list = array(
  "AL" => "Alabama ",
  "AK" => "Alaska ",
  "AZ" => "Arizona ",
  "AR" => "Arkansas ",
  "CA" => "California ",
  "CO" => "Colorado ",
  ... );

foreach ($state_list as $key => $value) {
  $selected = "";
  if ($key == $user_state)
  $selected = 'selected="selected"';
  // Loop HTML
  ?>
  <option <?=$selected?>value="<?=$key?>"><?=$value?>   </option>
  <?php		
  // End HTML		
}

?>
</select>

 

Keep in mind that I have short-tags enabled.

Hey thanks guys,

 

I figured out another way to do it...

 

 

So if you submitted a form check this by setting process == 1 and fill the options based on it..

 

<? if ($_POST['process'] == 1)

{

print $county;

}

else

{

print "Please Select...";

 

}

?>

The above seems to do the job . . but while I am on the subject, how would you approach it for radio buttons?

Hey . . doesnt matter . . I figured it out using

 

<input type="radio" name="contact_preference" value="Email" <? if ($_POST['process'] == 4)
						{
						if ($contact_preference == "Email")
						print "checked";
						}

						 ?>>
