I am building a website after reading this book, and I am having trouble with the selected="selected" part of a select menu. Nothing is getting selected. When I click on submit form it goes through but the item I selected isn't being selected in my database. 

 

In the following code, the problem lies in the following section: where the select menu is, but I can't get it to work. help would be appreciated. 

 

<?php
$optionarray = array(3 => 'Children & Family', 4 => 'Home Business', 5 => 'Advertising', 6 => 'Affiliate Programs', 7 => 'Art & Photography', 9 => 'Beauty & Jewelry', 10 => 'Blogging', 11 => 'Books, Literature', 12 => 'Business & Finance', 13 => 'Computer Games', 14 => 'Computing', 15 => 'Dating & Relationships', 16 => 'Directories', 17 => 'Education', 
18 => 'Electronics', 19 => 'Entertainment', 20 => 'Environment', 21 => 'Flowers', 22 => 'Food, Drink', 23 => 'Forums, chat rooms', 24 => 'Free Stuff', 25 => 'Gifts & Shopping',

echo '<form action="edit_your_sites.php" method="post"><select name="SiteTypeID"><option value="">Select a Category</option>';
 
foreach ($optionarray as $key => $value){
echo '<option value="$key"';
if (isset($_POST['SiteTypeID']) && ($_POST['SiteTypeID'] == '. $key . ')) echo 'selected="selected">'; 
echo $value . '</option>';
}
echo '</select>';
?>

I tried that and it shows that the array is empty. So post contains nothing. I am still unclear how to get my code to work though. What I am trying to do is replace a lot of hardcoded data with a foreach loop, however the key in my foreach loop isn't being selected and therefore my code isn't working. The problem might be with the selected="selected" part. Here is the hard-coded code, and below it is my new code with the foreach loop. The hardcoded code works perfectly.

You said that your POST array was empty when you posted the form, correct?

If that's the case, then that is your problem.

 

You need to figure out how to properly post your form.

Start with a much simpler form, and get it to the point where it's properly posting, and then the problem should become clear.

 

If the problem is related to something other than the POST array not being received, then you need to better describe your problem.

 

...And if you don't even know what your problem is, then you need to first work on better describing the problem for yourself before you try to explain it to us.

 

Thank you.

I will better explain my question so that it will deserve a proper answer. 

 

First at the top of my script I am validating that the field SiteTypeID is ok. 

if (!empty($scrubbed['SiteTypeID'])){
		$sitetypeid = $scrubbed['SiteTypeID'];
	} else {
		$sitetypeid ="";
		echo '<p class="error">Please select a category</p>';
	}

Then at the bottom of the script I have a select menu that is populated with an associative array and a foreach loop. However the $key variable is not working. It does not have a value between 3 and 43 like it should. Instead it's value is always 0. I want to know why it doesn't have the number value like it the keys in my associative array. 

 

Here is the code that shows the array and the select menu and the foreach loop.

$optionarray = array(3 => 'Children & Family', 4 => 'Home Business', 5 => 'Advertising', 6 => 'Affiliate Programs', 7 => 'Art & Photography', 9 => 'Beauty & Jewelry', 10 => 'Blogging', 11 => 'Books, Literature', 12 => 'Business & Finance', 13 => 'Computer Games', 14 => 'Computing', 15 => 'Dating & Relationships', 16 => 'Directories', 17 => 'Education', 
18 => 'Electronics', 19 => 'Entertainment', 20 => 'Environment', 21 => 'Flowers', 22 => 'Food, Drink', 23 => 'Forums, chat rooms', 24 => 'Free Stuff', 25 => 'Gifts & Shopping', 
26 => 'Health', 27 => 'Humor', 28 => 'Interior Design', 29 => 'Internet Marketing', 30 => 'Miscellaneous', 31 => 'Music', 32 => 'Pets', 33 => 'Real Estate', 34 => 'Religion & Spirituality', 35 => 'Science', 36 => 'Sports', 37 => 'Stocks & Trading', 38 => 'Travel', 39 => 'Vehicles', 40 => 'Web Design', 41 => 'Web Hosting', 42 => 'Work At Home', 43 => 'Psychology');
echo '<form action="edit_your_sites.php" method="post"><select name="SiteTypeID"><option value="">Select a Category</option>';
foreach ($optionarray as $key => $value){
	echo '<option value="$key"';
	if (isset($_POST['SiteTypeID']) && ($_POST['SiteTypeID'] == $key));
echo 'selected="selected">'; 
	echo $value . '</option>';
}
echo '</select>';

It's because you're using single quotes instead of double quotes.

Run your PHP and then look at the resulting source code. You'll see that each option element starts with the following:

<option value="$key"selected="selected">

Obviously, you don't want a value of "$key", and you don't want every option to have a value of selected, and you don't want the missing space between value and selected.

Basically, you have a bunch of mistakes in your code.

  1. Change value="$key" to value="' . $key . '".
  2. Get rid of the semicolon at the end of the if statement.
  3. Add a space before selected="selected".
  4. Move the ">" after selected to the beginning of the echo $value statement.

 

That should solve your problem.

In the future, if you're having a problem, look at the source code resulting from the PHP code, and look for problems.
