Create dynamic select fields in contact form 7. Requires Contact Form 7.

Field values of dynamic select field are populated by using filters.

How To Use

1) Create a filter to be called from your CF7 Dynamic Select Field.

Example Filter:

function cf7_dynamic_select_do_example1($choices, $args=array()) {
    // this function returns an array of 
    // label => value pairs to be used in
    // a the select field
    $choices = array(
        '-- Make a Selection --' => '',
        'Choice 1' => 'Choice 1',
        'Choice 2' => 'Choice 2',
        'Choice 3' => 'Choice 3',
        'Choice 4' => 'Choice 4',
        'Choice 5' => 'Choice 5'
    );
    return $choices;
} // end function cf7_dynamic_select_do_example1
add_filter('wpcf7_dynamic_select_example1', 
             'cf7_dynamic_select_do_example1', 10, 2);

2) Enter the filter name and any arguments into the Filter Field when adding a Dynamic Select Field.
For example, if we need to supply a term_id so that the filter can get the posts in a category the
filter value entered would look something like this:

my-filter term_id=9

Do Not Include any extra spaces or quotes arround values, names or the =

You can pass any number are arguments to your filter and they will be converted into an array. For example the
following:

my-filter product-type=101 brand=500

This will call the function assocaited with the filter hook ‘my-filter’ with an arguments the argument array of:
$args = array(
‘product-type’ => 101,
‘brand’ => 500
)

Your filter must return an array. The array must be a list of “Label” => “Value” pairs.
For more information see the example in cf7-dynamic-select-examples.php included in the plugin folder.
