I'm making an Computer Laboratory Monitoring System using CI framework.
I want to display the detail of the selected item in my list but i got an error says :
Message: Trying to get property 'invent_id' of non-object
Here's my code view code
<?php if(!empty($value)): ?>
<?php foreach($value as $post ): ?>
<tr>
<td data-field="id"><?php echo $post->invent_id;?></td>
<td data-field="id"><?php echo $post->name;?></td>
<td data-field="id"><?php echo $post->type;?></td>
<td data-field="id"><?php echo $post->stock;?></td>
<td>
<button name="view" data-toggle="modal" data-target="#exampleModal<?php echo $post->invent_id; ?>" class="btn btn-info view_data"> <span class="glyphicon glyphicon-eye-open">
</span></button>
<span class="glyphicon glyphicon-edit"></span>
<span class="glyphicon glyphicon-ban-circle"></span></td>
<?php $this->load->view('Modal/view_inventory_detail', $post); ?>
<?php endforeach; ?>
<?php else: ?>
<tr>
<td>No Records Found</td>
</tr>
<?php endif; ?>
</tr>
</tbody>
</table>
My controller
function inventory_list(){
$value['value'] = $this->Admin_Model->get_inventory();
$this->load->view('HeadtoFoot/header');
$this->load->view('Admin/inventory/list',$value);
$this->load->View('HeadtoFoot/footer');
}
And My Modal
<div class="modal fade" id="exampleModal<?php echo $post->invent_id; ?>" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">

<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
The Trying to get property of non-object error in CI generally happens when running a query. I would guess the error is happening in the call to the model:
$this->Admin_Model->get_inventory()

I have a problem with a bootstrap modal. I'm using PHP.
In an admin panel there is a table with the list of the users and the possibility to edit or delete a user's profile. For the delete I want to create a modal for the confirm of the delete but, when I click on "confirm" button inside the modal, the modal gets by default the user ID of the first user in the table and not the user ID of the selected user.
Here is the code:
<?php foreach ($utenti as $utente) { ?>
<tr>
<th scope="row"> <?php echo $utente['idUser']?> </th>
<td><?php echo $utente['nome']." ".$utente['cognome']?></td>
<?php if($_SESSION['role'] == 1) {?>
<td><?php echo $utente['az']?></td>
<?php } ?>
<td><?php echo $utente['email']?></td>
<td class="text-warning"><a
href="<?php echo 'editUser.php?user='.$utente['idUser']?>"><i
class="fas fa-edit text-warning"></i></a></td>
<!-- <td class="text-warning"><i class="fas fa-trash-alt text-danger"></i></td> -->
<td class="text-danger">
<button type="button" class="btn" data-toggle="modal"
data-target="#confirmDelete"><i
class="fas fa-trash-alt text-danger"></i><?php var_dump($utente['idUser']); ?>
</button>
</td>
<div class="modal" tabindex="-1" role="dialog" id="confirmDelete">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">
Attenzione <?php var_dump($utente['idUser']); ?></h5>
<button type="button" class="close" data-dismiss="modal"
aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>Continuando eliminerai l'utente in maniera irreversibile</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger "
><a
class="text-white btn-modal-confirm"
href="<?php echo '?action=delete&user='.$utente['idUser']?>"
>Elimina</a>
</button>
<button type="button" class="btn btn-secondary" data-dismiss="modal">
Indietro
</button>
</div>
</div>
</div>
</div>
</tr>
<?php }?>
If I make a var_dump of $utente['idUser'] before the modal, it gets the right user ID. If I make it inside the modal it gets by default the first ID, as I said.
Notice that every modal trigger button has a data-target attribute to define which modal will be opened.
In your case, the button of every row you used to triggered the modal have the same data-target, which is #confirmDelete. These modals behind also has the same id called #confirmDelete, so every time you hit the modal trigger button (all had the same data-target) then eventually it will shows up the very first modal element.
For a better understanding, compare my code to yours and see the differences.
<?php foreach ($utenti as $utente) { ?>
<tr>
<th scope="row"> <?php echo $utente['idUser']?> </th>
<td><?php echo $utente['nome']." ".$utente['cognome']?></td>
<?php if($_SESSION['role'] == 1) {?>
<td><?php echo $utente['az']?></td>
<?php } ?>
<td><?php echo $utente['email']?></td>
<td class="text-warning"><a
href="<?php echo 'editUser.php?user='.$utente['idUser']?>"><i
class="fas fa-edit text-warning"></i></a></td>
<!-- <td class="text-warning"><i class="fas fa-trash-alt text-danger"></i></td> -->
<td class="text-danger">
<button type="button" class="btn" data-toggle="modal"
data-target="#confirmDelete_<?php echo $utente['idUser']; ?>"><i
class="fas fa-trash-alt text-danger"></i><?php var_dump($utente['idUser']); ?>
</button>
</td>
<div class="modal" tabindex="-1" role="dialog" id="confirmDelete_<?php echo $utente['idUser']; ?>">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">
Attenzione <?php echo $utente['idUser']; ?></h5>
<button type="button" class="close" data-dismiss="modal"
aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>Continuando eliminerai l'utente in maniera irreversibile</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger "
><a
class="text-white btn-modal-confirm"
href="<?php echo '?action=delete&user='.$utente['idUser']?>"
>Elimina</a>
</button>
<button type="button" class="btn btn-secondary" data-dismiss="modal">
Indietro
</button>
</div>
</div>
</div>
</div>
</tr>
<?php }?>
In the above code, I gave every pair of modal elements (modal trigger button and modal ID) a unique data-target value and a unique element id.
...
<button type="button" class="btn" data-toggle="modal"
data-target="#confirmDelete_<?php echo $utente['idUser']; ?>">
...
<div class="modal" tabindex="-1" role="dialog" id="confirmDelete_<?php echo $utente['idUser']; ?>">
...
Now each pair of modal elements have their own ids and they should be working the way you wanted.
Currently i have a table that is generated via DB and i want to view the details of the selected value on the data table. I separated the modal with view/users/modal. but there's an error
Message: Trying to get property 'user_id' of non-object

I expect the output will display more information of the user but the actual output is an error message Message: Trying to get property 'user_id' of non-object
try to check what $row contains.
If -> don't work, try using $row['user_id']
I know this has been asked a lot but I haven't found any of the answers to the issue to be very fruitful. I essentially have a table inside a view that is displayed using a foreach loop in PHP, this spits out the records one by one and appends some 'Action' buttons in the last column (download, delete and edit). The download and delete functions work perfectly, I just pass the ID in from each record in the foreach loop, job done.
I'm having a lot of issues with my modal though, it only ever displays the data from the first record when I echo the data in the 'value' field of each input. I'm really stumped on how to make this functionality work (JQuery is not my strongest language). I've seen some responses talking about Ajax, but I'd rather not use Ajax in this project. I'm using the codeigniter framework also for some more info.
I think the issue is that the modal is only created once when the foreach loop starts running, hence why it only ever has the first record data inside the modal, any help to get around this so I can edit each individual record inside the table would be great! Thanks for the help.

JQUERY:
$('#myModal').on('show.bs.modal', function (e) {
// get information to update quickly to modal view as loading begins
var opener=e.relatedTarget;//this holds the element who called the modal
//we get details from attributes
var vsm_sn=$(opener).attr('vsm-sn');
//set what we got to our form
$('#profileForm').find('[name="vsm_sn"]').val(vsm_sn);
});
The best way to go about it , is to use events hooks which is tied to the modal to help manage dynamism on modals.
Take for example, you want to pass information from the for loop to the modal you can do this using just a modal and then update the modal as it opens.
check bootstrap docs you will see this hook for modal
show.bs.modal
we then use attributes from the button to pick out our information we are going to display on the modal, e.g
<button user-id="<?php echo $data[$i]->userID; ?>" first-name="<?php echo $data[$i]->firstname;?>">Edit</button>
then we can use Jquery to pick it up and hook it when the modal is opening
See for example code here, replace the static repeat with your dynamic coding
$('#myModal').on('show.bs.modal', function (e) {
// get information to update quickly to modal view as loading begins
var opener=e.relatedTarget;//this holds the element who called the modal
//we get details from attributes
var firstname=$(opener).attr('first-name');
//set what we got to our form
$('#profileForm').find('[name="firstname"]').val(firstname);
});

Run it and see the result, so you can change the table style to use loop in php and then echo your data as attribute.
Hope it helps.
assign an id to modal body, e.g. : modal-body
declare a variable to store the HTML for the modal body, e.g. var modalHTML = ''
then append the contents in the for loop to that variable.
after that append the variable to the modal body, using $('#modal-body).append($(modalHTML)).
I have a PHP loop that renders results from a Database:
<?php
foreach ($results as $result){
$job_numb = $result['job_numb'];
$job_name = $result['job_name'];
$comments = $result['comments'];
?>
<tr>
<td><?php echo "$job_numb";?> </td>
<td><?php echo "$job_name";?></td>
<td> <button type="button" class="btn btn-info btn-sm" data-toggle="modal" data-target="#Comments-<?php echo $job_numb;?>">Comments</button>
<!-- Modal -->
<div id="Comments-<?php echo $job_numb;?>" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Comments for <?php echo "$job_name" . "$job_numb";?></h4>
</div>
<div class="modal-body">
<?php echo "$job_name";?>
<?php echo "$comments";?>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</td>
<td>Edit Record</td>
</tr>
<?php
}
?>
The Data target for the modal cannot be a STATIC ID because then it's repeating IDs on the same page - so you will just repeat the same information as the first instance of the ID.
What I am after is to make sure the ID is always different for as many records as there are. I have seen the code before, but I cannot find it now. What am I missing?
Create a unique ID using <?php echo and a unique ID:
<button type="button" class="btn btn-info btn-sm" data-toggle="modal" data-target="#Comments-<?php echo $job_numb;?>">Comments</button>
<div id="Comments-<?php echo $job_numb;?>" class="modal fade" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Comments for <?php echo "$job_name" . " | " . "$job_numb";?></h4>
</div>
<div class="modal-body">
<?php echo "$comments";?>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
Using this, I was able to pass all of that dynamic row's specific data to the modal without ID conflicts. I hope this is useful to others seeking out the answer.
Giving the following manual:

It is quite easy to have a child view and echo it when I know captureTo used in the controller (e.g. "<?php echo $this->article ?>"), but can I do similar when I generate view models dynamically, and assign them to dynamically generated captureTo for addChild() function:
foreach ($studentEvaluations as $studEval) {
$studEvalId = $studEval->getEvalId();
$formViewModel = $this->buildStudentEvaluationViewModel($studEval);
$viewModel->addChild($formViewModel, $studEvalId);
}
I tried the following, but it does not work:
<?php foreach ($this->viewModel()->getCurrent()->getIterator() as $studId => $studEval) : ?>
<tr>
<td><?php echo $this->escapeHtml($studEval->fname); ?></td>
<td><?php echo $this->escapeHtml($studEval->lname); ?></td>

EDIT 1
This is an error when I try to output the view in the this way:
Catchable fatal error: Object of class Zend\View\Model\ViewModel could not be converted to string in C:\dev\projects\OnlineFieldEvaluation\module\OnlineFieldEvaluation\view\online-field-evaluation\online-field-evaluation\test3.phtml on line 62
I found how to do it. It was just my luck of knowledge in PHP:
<?php foreach ($this->viewModel()->getCurrent()->getChildren() as $studEval) : ?>

<td><?php echo $this->escapeHtml($studEval->lname); ?></td>
