I'm having a problem with Livewire passing an array to a route so I can print it to pdf. I've got:
public $selectedProducts = [];
public $selectedAlm = [];
public $nombreComponente, $data, $categoriaId;
public function mount()
{
$this->categoriaId = "0";
$this->nombreComponente = 'Reportes';
$this->data = [];
$this->artcero = 'si';
}
where $selectedProducts and $selectedAlm are arrays and my intention is to pass them to another controller to be able to print them to pdf, but I can't seem to find a way
here is my controller:
public function reportearticuloPDF($categoriaId, $artcero, $selectedAlm, $selectedProducts)
{
if ($selectedProducts > 0) {
$data = $selectedProducts;
} else {
if ($categoriaId == null) {
$data = Articulo::join('categorias as c', 'c.id', 'articulos.categoria_id')
->select('articulos.*', 'c.nombre as catnom')
->whereHas('detallearticulos', function($q) {
$q->whereIn('almacen_id', $selectedAlm);
})
->when($artcero == 'no', function($query){
return $query->where('stock', '>', 0);
})
->OrderBy('id', 'ASC')
->get();
} elseif ($categoriaId !== null) {
$data = Articulo::join('categorias as c', 'c.id', 'articulos.categoria_id')
->select('articulos.*', 'c.nombre as catnom')
->whereHas('detallearticulos', function($q) {
$q->whereIn('almacen_id', $selectedAlm);
})->with('detallearticulos')
->when($artcero == 'no', function($query){
return $query->where('stock', '>', 0);
})
->where('categoria_id', $categoriaId)
->OrderBy('id', 'ASC')
->get();
}
}
$pdf = PDF::loadView('admin.report.articulopdf', compact('data'));
return $pdf->stream('Reporte_de_articulo.pdf');
}
my routes in web.php:
Route::get('report/articulopdf/{categoriaId}/{artcero}/{selectedAlm}/{selectedProducts}', [ReportController::class, 'reportearticuloPDF'])->name('reportearticulo.pdf');
Route::get('report/articulopdf/{categoriaId}/{artcero}/{selectedAlm}', [ReportController::class, 'reportearticuloPDF'])->name('reportearticulo.pdf');
my button:
<a href="{{ url('report/articulopdf' . '/' . $categoriaId . '/' . $artcero . '/' . $selectedAlm . '/' . $selectedProducts) }}"
class="btn btn-danger btn-sm btn-block {{ count($data) < 1 ? 'disabled' : '' }}" target="_blank">
Exportar reporte a PDF <i class="fas fa-file-pdf"></i></a>
that's the one that gives me the Array to string conversion error. I also tried it this way:
<a href="{{ route('reportearticuloPDF', $categoriaId, $artcero, $selectedAlm, $selectedProducts) }}"
class="btn btn-danger btn-sm btn-block {{ count($data) < 1 ? 'disabled' : '' }}" target="_blank">
Exportar reporte a PDF <i class="fas fa-file-pdf"></i></a>
but it gives me the error Too few arguments to function App\Http\Controllers\ReportController::reportearticuloPDF(), 0 passed in C:\xampp\htdocs\sistemainventarioGDS\vendor\laravel\framework\src\Illuminate\Routing\Controller.php on line 54 and exactly 4 expected
In your routes you create two routes with the same method and same function reportearticuloPDF in the controller with different params !!
I have a dependent drop down that get the category on the first drop down and should get the subcategory on the second drop down but the subcategory drop down isn't populated. I have something like this in my Model:
public function category()
{
$response = array();
$this->search(array(), 'date_created');
$this->db->select('*');
$query = $this->db->get('categories');
$response = $query->result_array();
return $response;
}
public function sub_category($parent_id)
{
$query = $this->db->get_where('sub_categories', array('parent_id' => $parent_id));
return $query->result_array();
}
And then something like this on my Controller:
public function edit_product($id)
{
$data['title'] = 'Update Product';
$this->load->view('../admin/template/admin_header');
$products = new Admin_model;
$data['products'] = $products->edit_product($id);
$data['category'] = $this->Admin_model->category();
$data['subcategory'] = $this->Admin_model->sub_category($data['products']->category_id);
$this->load->view('../admin/template/admin_topnav');
$this->load->view('../admin/template/admin_sidebar');
$this->load->view('../admin/products/manage_product', $data);
$this->load->view('../admin/template/admin_footer');
}
function get_subcategory()
{
if ($this->input->post('parent_id')) {
echo $this->Admin_model->get_subcategory($this->input->post('parent_id'));
}
}
public function insert_product()
{
$productData = array();
if ($this->input->post('productData')) {
$this->form_validation->set_rules('category_id', 'Category', 'required');
$this->form_validation->set_rules('sub_category_id', 'Sub Category', 'required');
$this->form_validation->set_rules('product_name', 'Product Name', 'required');
$this->form_validation->set_rules('department', 'Department', 'required');
$this->form_validation->set_rules('description', 'Description', 'trim|required');
$this->form_validation->set_rules('status', 'Status', 'required');
if ($this->form_validation->run() == true) {
$ori_filename = $_FILES['product_image']['name'];
$update_image = time() . "" . str_replace(' ', '-', $ori_filename);
$config = [
'upload_path' => './images/products',
'allowed_types' => 'gif|jpg|png',
'file_name' => $update_image,
];
$this->load->library('upload', $config);
if (!$this->upload->do_upload('product_image')) {
$error = array('error' => $this->upload->display_errors());
$this->load->view(base_url('admin/products'), $error);
} else {
$image = $this->upload->data('file_name');
$productData = array(
'category_id' => $this->input->post('category_id'),
'sub_category_id' => $this->input->post('sub_category_id'),
'product_name' => $this->input->post('product_name'),
'department' => $this->input->post('department'),
'description' => $this->input->post(htmlentities('description')),
'status' => $this->input->post('status'),
'upload_path' => $image
);
$img = new Admin_model;
$img->insert_product($productData);
$this->session->set_flashdata('status', 'Package InsertedSuccesfully');
redirect(base_url('admin/products'));
}
}
}
$data['title'] = 'Insert Product';
$data['category'] = $this->Admin_model->category();
$data['subcategory'] = $this->Admin_model->get_subcategory();
$this->load->view('../admin/template/admin_header');
$this->load->view('../admin/template/admin_topnav');
$this->load->view('../admin/template/admin_sidebar');
$this->load->view('../admin/products/manage_product', $data);
$this->load->view('../admin/template/admin_footer');
}
And then the view:
<div class="form-group">
<label for="" class="control-label"> Category</label>
<select name="category_id" id="category" class="custom-select select">
<option value="">Select Category</option>
<?php
foreach ($category as $row) {
echo '<option value="' . $row['id'] . '"';
if (isset($products) && $row['id'] == $products->category_id) {
echo ' selected';
}
echo '>' . $row['category'] . '</option>';
}
?>
</select>
</div>
<div class="form-group">
<label for="" class="control-label">Sub Category</label>
<select name="sub_category_id" id="subcategory" class="custom-select select">
<option value="">Select Sub Category</option>
<?php
foreach ($subcategory as $row) {
echo '<option value="' . $row['id'] . '"';
if ($row['id'] == $products->sub_category_id) {
echo ' selected';
}
echo '>' . $row['sub_category'] . '</option>';
}
?>
</select>
</div>
And here's the script. I'm not really familiar at AJAX so i tried to ask and get answers here which helps me progress but I still can't populate the subcategory drop down.
<script type="text/javascript">
$(document).ready(function() {
$('#category').change(function() {
var parent_id = $('#category').val();
console.log(parent_id)
if (parent_id != '') {
$.ajax({
url: "<?php echo base_url(); ?>admin/get_subcategory",
method: "POST",
data: {
parent_id: parent_id
},
success: function(data) {
$('#subcategory').html(data);
console.log(data)
}
});
} else {
$('#subcategory').html('<option value="">Select Category First</option>');
}
});
});
Also, here's what I get in the console
The result from $this->Admin_model->sub_category(...) is an array.
echo works on string values only, which is why you're getting the error. You'll need to loop over the result array (in admin/get_subcategory) and print the values one by one. Also surround each value with an <option> tag so the result can be placed in the select box without further modification:
public function get_subcategory() {
if ($this->input->post('parent_id')) {
$subcategories = $this->Admin_model->sub_category($this->input->post('parent_id'));
foreach ($subcategories as $subcategory) {
echo '<option value="'.$subcategory['id'].'">'.$subcategory['sub_category'].'</option>';
}
}
}
if ($request->ajax()) {
$data = User::latest()->get();
return Datatables::of($data)
->addIndexColumn()
->addColumn('FullName', function($row){
$name = $row->fname.' '.$row->lname;
return $name;
})

Hello, I want to use #can('user-create') in Controller datatable Yajra so that a user does not see the button in he has no access.
I can do it in blade but not in controller.
I want to check if the role has the permission to perform tasks in that way.
Otherwise my code is running fine only this is making it tiresome.
You can do it in 2 ways :
checking permission in the controller
Eg. :
if ($request->ajax()) {
$data = User::latest()->get();
// get logged user
$user = auth()->user();
return Datatables::of($data)
->addColumn('action', function($row) use ($user) {
$btn = '';
if ($user->can('user-show') {
$btn = '<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups"><div class="btn-group" role="group">
<span class="icon-size-fullscreen"></span> Show';
}
if ($user->can('user-edit') {
$btn = $btn.'<span class="icon-pencil"></span>';
}
$btn = $btn.'<span class="icon-trash"></span> </div></div>';
return $btn;
})
->rawColumns(['action'])
->make(true);
}
or Another Way
if ($request->ajax()) {
$data = User::latest()->get();
return Datatables::of($data)
->addIndexColumn()
->addColumn('FullName', function($row){
$name = $row->fname.' '.$row->lname;
return $name;
})
->addColumn('actions', 'path.actions')
->rawColumns(['FullName'])
->escapeColumns([])
->make(true);
}
and your blade file be like
#can('user-edit')
Your code
#endcan
If you use spatie permission plugin, you can use $user->can('permission') in your controllers.
Here :
if ($request->ajax()) {
$data = User::latest()->get();
// get logged user
$user = auth()->user();
return Datatables::of($data)
->addIndexColumn()
->addColumn('FullName', function($row){
$name = $row->fname.' '.$row->lname;
return $name;
})
->addColumn('action', function($row) use ($user) {
$btn = '';
if ($user->can('user-show') {
$btn = '<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups"><div class="btn-group" role="group">
<span class="icon-size-fullscreen"></span> Show';
}
if ($user->can('user-edit') {
$btn = $btn.'<span class="icon-pencil"></span>';
}
$btn = $btn.'<span class="icon-trash"></span> </div></div>';
return $btn;
})
->rawColumns(['FullName'])
->rawColumns(['action'])
->escapeColumns([])
->make(true);
}
I am trying to resize multiple images at once in my foreach loop but does not do it. It only resizes some of them per page.
Question how can I make sure it resizes the multiple images at once in my foreach loop on index()
As you can see it only resizes some of them the filemanager code is run/loaded ajax
<?php

Try adding an error handler on resize() to see if there's an error that's preventing an image from getting resized:
$this->image_lib->clear();
$this->image_lib->initialize($config);
if (!$this->image_lib->resize()) {
echo $this->image_lib->display_errors();
}
Update
It seems the segment is not initialized correctly
$segment = $this->input->get('per_page');
Instead try
$segment = $this->input->get('page') * $this->input->get('per_page');
Solution
I have working solution now
I have had to make a check of the directory
if (!is_dir(DIR_IMAGE . 'cache/' . $new_image)) {
if ($this->input->get('directory')) {
#mkdir(DIR_IMAGE . 'cache/catalog/' . $this->input->get('directory') .'/', 0777, true);
} else {
#mkdir(DIR_IMAGE . 'cache/catalog/', 0777, true);
}
}
And also use use a if file exists for resize check and also codeigniter img() helper function helped also.

I have this menu function below that I use to get a list of forums and categories.
Each time i need to get a new level I have to add a foreach loop in the menu function. I would like to be able to only have one or two foreach loops that can get ever level belonging to that forum
Question: How can I Only have one or two foreach loops in my menu
function that can get multiple levels of categories

$html = '';

You can use directly option tag in your get_forums($pid) method. I hope it's can helpful for you.
Forum_model.php
<?php
public function get_forums($pid) {
$forums = '';
$this->db->select('*');
$this->db->from('forum');
$this->db->or_where('pid', $pid);
$query = $this->db->get();
foreach($query->result_array() as $result){
$forums .= '<option value="'.$result['fid'].'" class="optionChild">'.$result['name'].'</option>';
$this->get_forums($result['fid'])
}
return $forums;
}
?>
In View Page :
<select name="pid" class="form-control">
<option value="0">None</option>
<?php foreach ($categories as $category) {?>
<option value="<?php echo $category['fid'];?>" class="optionParent"><?php echo $category['name'];?></option>
<?php echo $category['forums']; ?>
<?php } ?>
</select>
I have a solution.
I got the idea from here https://gist.github.com/YavorK/5578b4f1b32fe125e0f7eab214270c30
Some small changes for a select option instead of ul. And made library instead.
<?php

$this->CI =& get_instance();

$html = '';
$html .= '<select name="'.$name.'" class="form-control">';
$html .= $this->create_option($this->getforums());
$html .= '</select>';
return $html;
}
function create_option($items, $startingParentId = 0)
{
$htmlOutput = '';
foreach ($items as $item) {
if ($item['pid'] != $startingParentId) {
continue;
}
$htmlOutput .= '<option value="'. $item['fid'] .'">' . $item['name'] . '</option>';
$htmlOutput .= $this->create_option($items, $item['fid']);
}
return $htmlOutput;
}
public function getforums() {
$this->CI->db->select('*');
$this->CI->db->from('forum');
$query = $this->CI->db->get();
if ($query->num_rows() > 0) {
return $query->result_array();
} else {
return false;
}
}
}
