Multi-select list values on POST

[qwerty234]

Hi,

 

In my HTTP header I've collected the following values from a multi-select list after my POST:

project_list=community_name&project_list=project_number&project_list=map_letter&project_list=home_type

 

Here's my PHP code to loop thru the project_list after the POST. For some reason my array $a is not being populated, do you see why?

 

     
$a = array();

foreach ($_POST['project_list'] as $selected) 
{
        if ($selected == 'community_name'){
                    $a[] = "projects.project_name ";
        }

        if ($selected == 'project_number'){
                    $a[] = "projects.project_number ";
        }

        if ($selected == 'map_letter'){
	      $a[] = "projects.map_letter ";
        }

        if ($selected == 'home_type'){
                    $a[] = "home_types.home_type ";
        }
.
.
.

If I understand what you're trying to do correctly then put in your code

 

echo '<pre>'
print_r ($_POST);
echo '</pre>';

 

then submit the form and look at the results. I'm guessing you didn't set the input tags as an array in the html.

 

Also a switch would be better instead of all of those if statements since you are only looking at a single variable.

I see two things wrong with the following line based on what I'm reading:

 

project_list=community_name&project_list=project_number&project_list=map_letter&project_list=home_type

 

If this is what you're seeing in the URL after you submit your form, then you are passing your form variables using the $_GET array, not the $_POST array. Change your form submit method to "POST" if you are not already.

 

Additionally, if you're trying to pass a multi select list from an HTML form, you have to append brackets to the end of the form element name. So instead of using "project_list" for the name, you would need to use "project_list[]". Otherwide, each time a"project_list" value was defined, it would overwrite the existing value because the value is being treated as a string. If you use "project_list[]", then each new definition will add an element to the array, as the values would be treated as array elements.

 

Good luck!
