PHP - Recursively Remove All Array Elements Which Are Not Of Given Type

I have a dropdown list which have some elements.
I want to get all the elements of the dropdown list into a variable of type array.

Any Idea???

Hello everyone I'm very new here but i hope you could help me with a tricky problem I no longer know how to approach it because it's difficult to visalize the solution.

Anyway, I have a script that goes to the root of a site (with cURL) and picks up categories (links on the site) via regex.
All the links are placed  into the big array I have. The first layer (dimension) I've managed to create but the problem comes to when I need my script to delve into deeper dimensions.

I want, for each link it finds, go to that page and find those subcategories and place it in my array in the correct subarray. If the regex returns 0 matches, go up one step and go to the next node's site, until the whole big array has been exhausted.

Is this possible? Please help out guys and gals. I'll provide more info and code if requested.

Hi, I have a multidimensional array where each array has a parent id node to create a hierarchical tree.


$hierarchy[] = array('id' => 1, 'parent_id' => 0, 'name' = 'root1');
$hierarchy[] = array('id' => 2, 'parent_id' => 0, 'name' = 'root2');
$hierarchy[] = array('id' => 3, 'parent_id' => 1, 'name' = 'root1-1');
$hierarchy[] = array('id' => 4, 'parent_id' => 1, 'name' = 'root1-2');
$hierarchy[] = array('id' => 5, 'parent_id' => 3, 'name' = 'root1-1-1');
$hierarchy[] = array('id' => 6, 'parent_id' => 2, 'name' = 'root2-1');


I'm trying to come up with a recursive key/value search routine that will return all ancestor arrays of the found item without knowing the depth of the tree.  All nodes with 0 for the parent_id are root level nodes.

Basically I want to search for something like "where key = name and value = xxx" and have it return all ancestors of that node.

So if I wanted to search for "key = name and value = root1-1", it should return and array like:

array[0] = array('id' => 1, 'parent_id' => 0, 'name' = 'root1'); //parent node first
array[1] = array('id' => 3, 'parent_id' => 1, 'name' = 'root1-1');  //first child after parent

if I was to search for "key = name and value = root1-1-1", it should return:

array[0] = array('id' => 1, 'parent_id' => 0, 'name' = 'root1'); //parent node first
array[1] = array('id' => 3, 'parent_id' => 1, 'name' = 'root1-1');  //first child after parent
array[2] = array('id' => 5, 'parent_id' => 3, 'name' = 'root1-1-1'); //first grandchild

So the main problem comes in the iteration and keeping track of parents.  If I just want the array with the answer I can get that node, but I can't get it with all of the ancestors attached.  How would you go about this?  Any good ideas out there?

Thanks!

How can I make it so that the things that the user recently typed in an input is not displayed as a drop down.  I want nothing to be displayed. 

Long time lurker, first time poster here.  I am having a problem with a multiple file uploader form I am trying to build.  I am using the CodeIgniter framework, but I believe my problem is with the form itself.

Here is the form:
Code: [Select]
<form action="http://localhost/show/submit" id="sendfiles" method="post" name="sendfiles" enctype="multipart/form-data">   
<input type="hidden" name="doup" value="1" />
    <input type="file" name="userfile1" value="" id="userfile1" size="20"  />    <br />
    <input type="file" name="userfile2" value="" id="userfile2" size="20"  />    <br />
    <input type="file" name="userfile3" value="" id="userfile3" size="20"  />    <br />
    <input type="submit" name="submit_btn" value="Upload"  />    </form>   
   

The form is being passed to this function:


if(empty($_POST['doup'])){
            foreach($_REQUEST as $k => $v)
                print ">>> $k : $v <br />";
                
            $data['form_open'] = form_open_multipart(uri_string(), array(
                'id' => 'sendfiles',
                'method' => 'post',
                'name' => 'sendfiles'    
            ));
            $data['form_flag'] = form_hidden('doup', '1');
            $data['file1'] = form_input(array(
                'id' => 'userfile1',
                'name' => 'userfile1',
                'size' => '20',
                'type' => 'file',                
            ));
            $data['file2'] = form_input(array(
                'id' => 'userfile2',
                'name' => 'userfile2',
                'size' => '20',
                'type' => 'file',                
            ));
            $data['file3'] = form_input(array(
                'id' => 'userfile3',
                'name' => 'userfile3',
                'size' => '20',
                'type' => 'file',                
            ));
            $data['form_submit'] = form_submit('submit_btn', 'Upload');
            $data['form_close'] = form_close();           
            $this->load->view('show/submit', $data);
        } else {
            $config['allowed_types'] = 'mp3';
            $config['max_size']    = '10240';
            $config['upload_path'] = $this->config->item('file_upload_path');
            $uploaded_files = array();
            for($nona=1; $nona<4; $nona++){
                if (strlen($_FILES['userfile'.$nona]['tmp_name']) <=0){
                    echo  "tempname$nona failed";
                    continue;
                }
                
                    
                //print "------ USERFILE $nona ------ <br />";
                //print sizeof($_FILES['userfile'.$nona])."<br />";
                //foreach ($_FILES['userfile'.$nona] as $k => $v){                    
                //    print "$k  :  $v <br />";
                //}
                        
                $this->upload->initialize($config);
                $upload = $this->upload->do_upload('userfile'.$nona);
                if (!$upload){
                    $form_errors = array('form_errors' => $this->upload->display_errors());
                    $this->load->view('show/submit', $form_errors);
                    break;
                } else {
                    $data = array('upload_data' => $this->upload->data());
                    $data = $data['upload_data'];
                    $fp = $data['full_path'];
                    $filename = strtolower(random_string('numeric', 16) . $data['file_ext']);
                    $rel_path = 'show/submissons/uploaded/';
                    $path = $this->config->item('media_root_path') . $rel_path;
                    
                    exec('mkdir -p ' . $path , $a1, $r1);
                    exec('mv ' . $fp . ' ' . $path .  $filename, $a2, $r2);
                    
                    array_push($uploaded_files, $path .  $filename);
                }
                
            }
            $this->session->set_flashdata('img_data',implode("||", $uploaded_files));
           // redirect("show/submit_info");
        }    



The problem is this:

When I choose only one file to upload, it works.  I can choose any of the 3 inputs and it works great.  But as soon as I try to choose 2 or more files, the form fails to post.  When I press submit, the page simply reloads and none of the form variables get posted.  I have checked settings in php.ini and tried building and rebuilding this form.  I'm hoping someone here can provide some insight into what I'm doing wrong?
