Conditionals and in_array...

[LWillmann]

I have created a table, and in that table I have fields. Some of those fields store multiple values (a group of checkbox values). The selected items are stored in the fields as comma seperated strings (using PHP's implode).

I have created a page, and on that page, I have managed to get it to pull the data from that table. I run the resultset through a foreach loop to do some testing.

PHP Code:

foreach ($read as $key => $data)
{
    if ($key == 'bodyart')
        $bodyart = explode(", ", $data);
} 


Then in my template I have a series of checkboxes, here is one for example:

<input type="checkbox" name="bodyart[]" value="Pierced tongue" 
<if condition="in_array('Pierced tongue', $bodyart)">checked</if> 
/>

This is attempting to see if the value for this checkbox is in the bodyart array, and if it is, then print checked so the box is checked.

When I attempt to save the template in the ACP I get this message:

Warning: in_array(): Wrong datatype for second argument in /includes/adminfunctions_template.php(3537) : eval()'d code on line 364

In my source file for the page, I have declared $bodyart as global and as an array, but it still gives me the error.

PHP Code:

global $bodyart;
$bodyart = array(); 


If I click continue and go on and save the template, and load the page, it shows the proper box checked. So technically it works. But how do I keep from getting this warning on my template for each instance of that array?
