Invalid argument supplied for foreach()

[Deanznet]

I am having problem with my edit.php page,

 

Keep on getting Invalid argument supplied for foreach()

 

My edit.php is suppose to get the drop down list from the first page. and replace the string [Replace] with whats in the list box But it has to Use the first thing in the list box 2 times, and ect.

 

 

<form method="post" action="edit.php" >

<select name="drop1">
<?php echo $dropdownOptions; ?>
</select>
<input type="submit" value="drop1" />
</form>

 

 

Edit.php

 

<?

$file = file_get_contents('myfile.txt');

foreach($_POST['drop1'] as $replace) {

    

$file = preg_replace('#\[Replace\]#', $replace, $file, 2);
}

?>

By default, a select menu will only have one value, so you don't need the foreach loop at all. If you want the user to be able to select more than one value, you need to use the 'multiple' attribute. You would also need to make the name an array:

<select name="drop1[]" multiple="multiple">
<?php echo $dropdownOptions; ?>
</select>

Then your foreach loop would work.

As khizar said, $_POST['drop1'] is not an array, it's a string. foreach() needs an array to loop over.
