Hi,
For my first CI4 project I'm developing a document management system for home so I can store scanned paper documents etc.
The principal table is for documents (dms_documents) that has fields for file name, document date, category (image, letter, user guide etc) etc. The categories are taken from the category table (dms_category) that populates an HTML select input box on the document add form/View.
On startup I have a View page that list all documents in a paged table View, created in my Document Controller and passed to the View thus:
Code:
class DocumentController extends BaseController
{
// show documents list
public function index(){
$documentModel = new DocumentModel();
$data['dms_documents'] = $documentModel->orderBy('filename', 'DESC')->findAll();
return view('pages/document_table_view', $data);
}
}
To populate the Category select options in the document add form/View I have this in the Controller:
PHP Code:
// add document form
public function createInCategory($name)
{
helper(['form']);
$documentModel = new DocumentModel();
$db = \Config\Database::connect();
$queryCategory = $db->query("SELECT `name` FROM `dms_category` WHERE `name` LIKE '%' ORDER BY `name` ASC");
$data = [
'selected_category' => $name,
'dms_category' => $queryCategory->getResultArray(),
'review' => Time::today('Europe/London', 'en_GB')->addMonths(12),
];
return view('pages/document_add_form', $data);
}
And in the document add form I have this:
PHP Code:
<div class="form-group">
<label for="category">Category<span class="requiredIcon">*</span></label>
<select name="category" id="category" class="form-control">
<option value="Select Category">Select Category</option>
<?php if($dms_category): ?>
<?php foreach($dms_category as $cat): ?>
<option value="<?= $cat['name'] ?>"> <?= $cat['name'] ?></option>
<?php endforeach ?>
<?php endif ?>
</select>
</div>
This all works fine, except that I now want to introduce a foreign key and referential integrity, so that changing the category name/spelling in the dms_category table will cascade through affected records in the dms_documents table. I know I really should change <option value="<?= $cat['name'] ?>" to <option value="<?= $cat['id'] ?>" but then my category field in the dms_documents table says '14' rather than 'Letter', and '14' is displayed in the initial document table view.
So, how do I go about substituting the category name for the id in the View? I suspect the answer lies in the Document Controller index() function, and that I need to get the document data as an array then adjust the data that is sent to the View...
Thanks
Substitute name for id
