Help with invalid argument with foreach

[msaz87]

Hey all,

 

I'm getting the following error and am not sure why:

 

Warning: Invalid argument supplied for foreach() in /[PATH TO]/[FILE].php on line 97

 

I'm using about five or six foreach's and this is the only one failing...

 

	foreach($_POST['manager'] as $key => $value){
	list($payment_id,$d) = explode('|',$key); 

		mysql_query("	UPDATE [DB].other_payments SET
				manager_id		= '$value' 
				WHERE other_payment_id 	= '$payment_id'")
		or die(mysql_error());	 

	}

 

The code for the form is:

 

						<select name="manager[<?php echo $payment_id; ?>|i]">	

							<?php

								$managers_list_query = "	SELECT * FROM [DB].user 
												ORDER BY user_name";

								$managers_list_results = mysql_query($managers_list_query) or die(mysql_error());

								while($row = mysql_fetch_array($managers_list_results)){

							?>

							<option <?php if($manager == $row['user_id']) echo "selected" ?> value="<?php echo $row['user_id']; ?>"><?php get_manager_name_from_id($row['user_id']) ?></option>

							<?php } ?>	

						</select>

 

... and a look at how the above code outputs onto the page:

 

						<select name="manager[2|i]">	


							<option  value="1">User 1</option>


							<option  value="6">Darren</option>


							<option  value="13">Elliot</option>


							<option  value="5">Eric</option>


							<option  value="9">Julia</option>


							<option  value="11">Lee</option>



							<option selected value="4">Matt</option>



							<option  value="7">Richard</option>


							<option  value="3">Ryan</option>



						</select>

 

And before you ask, the $d variable isn't used for anything... it's just sort of the result of me copying and pasting this same foreach over and over and just never taking it out...

 

Any help is greatly appreciated -- thanks!

$_POST['manager'] is not an array?

See what happens when you do (instead of the foreach):

print_r($_POST['manager']);

See what happens when you do (instead of the foreach):

print_r($_POST['manager']);

 

It spits out only one value... so it would seem teamatomic is correct in that it isn't an array -- any ideas what I'm doing wrong?

 

Thanks for the help!

I was able to resolve the problem by simply changing the name of the select field... I'm not entirely certain why that made a difference -- must be something elsewhere in my code.

 

Thanks for the help!
