Question

any help would be much appreciated.

I have a select/option box passing a $_GET array into a php controller that passes this value into a model retrieving some MySQL.

However I am up to the stage where I am just wishfully stabbing at this now. I think the problem is with the array though.

<select id="frm_type" style="margin-left:180px; width: 136px; height:100%;" name="uid[]" multiple="multiple">
    <option value="U4BC3128209B01">All Users</option>
    <option value="U4D88B8CFE7579">more options</option>        
</select>

The $_GET looks like this ?&uid%5B%5D=U4DFF15A4581A4&uid%5B%5D=U4D88B8CFE7579
This comes into the controller like so…

$filter_in = $_GET;

then is called into the model like this.

$body_data['user_stats'] = $this->mtvm_model->user_stats($filter_in);

Then finally the relevant section that wants to use it does this:

        if ($filter_in['uid'] != '')
        {
        $sqlQuery .= " AND ";

        foreach($filter_in['uid'] as $key=>$value)
            {
            $sqlQuery .= " ".$this->tables_calls.".userId = '".mysql_real_escape_string($value)."' ";
            if($key != count($filter_in['uid'])-1) 
                {
                $sqlQuery .= " OR ";
                }
            }
        }

Is it simply that I am incorrectly trying to pass an array as $filter_in['uid']?

Answer 1

The query string:

uid%5B%5D=U4DFF15A4581A4&uid%5B%5D=U4D88B8CFE7579

implies that $_GET["uid"] looks like this:

Array
(
    [0] => U4BC3128209B01
    [1] => U4D88B8CFE7579
)

Your should check for the presence of this variable like this:

if (isset($filter_in['uid']) && is_array($filter_in['uid'])) {
    // ...
