This code should list all of the missing majors from the database to the blade file. The database query successfully retrieves the correct data, but it is not rendering in the blade?
for($i=0;$i<sizeof($majors_array1);$i++)
{ if (School::where('major', '=', $majors_array1[$i])->exists())
{ echo $majors_array1[$i] . ' ' ." found"."<br/>";}
else
{ return view('enter-school-dept')->with('majors_array1',
$majors_array1[$i]);}
}
<table>
<tr>
<th>Title</th>
<th>School</th></tr>
<tr>
#foreach (majors_array1 as $majors)
<td>$majors</td>
#endforeach

I am getting the error:
Use of undefined constant majors_array1 - assumed 'majors_array1' (this will throw an Error in a future version of PHP) (View: C:\xampp\htdocs\test\resources\views\enter-school-dept.blade.php)
Replace your foreach:

With:
#foreach ($majors_array1 as $major)

I want to loop through the following json object:
{countryId: 1, countryName: 'Bangladesh4', countryShortName: 'BD4', authStatus: 'U', createdBy: 'nasir', …}
I want to show this json object as follows:
Country Id: 1
Country Name: Bangladesh
and so on. Actually I need to add a space at every capital letter of a camel case word and make the first letter capital. How can I do this in vue 3?
My try:
<table>
<tbody>
<tr v-for="(value, key) in data">
<th>{{ key }} </th>
<td>{{ value }}</td>
</tr>
</tbody>
</table>
I have not tested this code. But I would create a computed property, which creates an object with the correct labels based on the keys in the data:
const labels = computed(() => {
const newLabels = {}
data.forEach(item => {
Object.key(key => {
newLabels[key] = key.replace( /([A-Z])/g, " $1" );
})
})
return newLabels;
})
The object created should look like this: {countryId: 'country Id', countryName: 'country Name', ...}. It is flexible as it will run over all objects in the data array, collecting and converting all possible keys. Downside may be performance when you have a huge array. If all keys are the same for the objects in data, you also just might create a labels object manually.
Now you can use this in your template:
<th style="text-transform: capitalize;">{{ labels[key] }} </th>
I added the style to transform the first letter to a capital.
As said, I did not have an opportunity to test this, but I hope it helps you any further.
you can display name as below
<table>
<tbody>
<tr v-for="(value, key) in data">
<th v-if="key=='countryId'">Country Id</th>
<th v-if="key=='countryName'">Country Name</th>
...
<td>{{ value }}</td>
</tr>
</tbody>
</table>
I know how can i use if else statement or for loop using .ejs file but i need to change code in .hbs file and i am new with this.Please help me with below example in which i have used .ejs file i need to convert it in .hbs file but don't know how to change if else and for loop

I have used below code but it is not working as i am new i need your guidence
#76484 i have used this ``` {{#if userData.length != 0 }}
{{var i =1;}}
{{userData.forEach(function(data))}}

{{i++; })}}
{{else{} }
<tr>
<td colspan="7">No Data Found</td>

{{}}}
</table>
</div>
</body> ``` but it is not working
The primary difference between your embedded JS example and Handlebars is that Handlebars does not execute arbitrary JavaScript, like your .forEach loop. Instead, Handlebars provides helpers to allow you to do things like conditionals and iteration.
First, we will tackle your condition, if (userData.length != 0). Handlebars has a #if helper which we could use to check if userData has a truth (greater than 0) length. The result would be:
{{#if userData.length}}
{{! TODO: output each user data}}
{{else}}
<tr>
<td colspan="7">No Data Found</td>
</tr>
{{/if}}
Secondly, Handlebars has an #each helper which is used for looping over collections as you are doing with your userData.forEach(function(data) { /*...*/ } code. For your purposes, the syntax would be:
{{#each userData}}
<tr>
<td>{{ #index }}</td>
<td>{{ fullName }}</td>
<td>{{ emailAddress }}</td>
<td>{{ city }}</td>
<td>{{ country }}</td>
<td>Edit</td>
<td>Delete</td>
</tr>
{{/each}}
Notice how we are evaluating the properties of each object in our userData array. There is no =. We just wrap the property name in double-handlebars, like {{ fullName }}. Handlebars handles the execution context within the #each so that we are always referring to the current iteration of our array.
Also notice the {{ #index }}. This is a special variable provided by Handlebars to give us the current iteration index within our #each loop. It is zero-index, so our output will be slightly different from your ejs example because you initialized your counter at 1.
Unfortunately, if we want our indexes to be one-based, we will have to write a custom helper to this. Our helper would just need to take a number, #index, and increment it by 1. It would look like:
Handlebars.registerHelper('increment', function (num) {
return num + 1;
});
And we would update our template to make use of it:
{{increment #index }}
I have created a fiddle with the final example for your reference.
I have an entity called worker and each worker has a property called active which is boolean.
My twig is an index that shows the list of workers with active=true.
I have a button in front of each worker, when I press this button I want it to change that worker's active property to false.
The problem: I couldn't figure out how to change that value in the controller without making a form since I'm still an amateur when it comes to Symfony
Here's my twig:
<table id="file_export" class="table table-striped table-bordered">
<thead>
<tr>
<th>ID</th>
<th>First Name</th>
<th>Last name</th>
<th>Active</th>
<th>edit</th>
</tr>
</thead>
<tbody>
{% for worker in workers %}
<tr>
<td>{{ worker.id }}</td>
<td>{{ worker.Firstname }}</td>
<td>{{ woker.Lastname }}</td>
<td>{{ worker.active ? 'active' : 'inactive' }}</td>
<td>
<i class="fa fa-pencil"></i>
</td>
</tr>
{% endfor %}
</tbody>
</table>
and my controller (which doesn't work):
/**
* #Route("/{id}/edit", name="worker_edit", methods={"GET","POST"})
*/
public function edit(Request $request, Worker $worker): Response
{
if ($this->isCsrfTokenValid('edit'.$worker->getId(), $request->request->get('_token'))) {
$worker->setActive(false);
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($worker);
$entityManager->flush();
}
return $this->redirectToRoute('index');
}
you actually have to add a csrf token to your path call:
path('worker_edit', {'id': worker.id, '_token': csrf_token('worker'~worker.id)})
or otherwise your check for the csrf token obviously cannot succeed.
however, since a link will trigger a GET request, you have to look into
$request->query->get('_token')
in the isCsrfTokenValid call.
As a hint: give your routes and actions semantically better names. Like ... "worker_deactivate", if it is used to deactivate a worker (which it apparently is). it's also quite common, to call the routed methods of a controller actionAction, so that would be deactivateAction.
If you want to make HTTP requests without reloading the web page, then you've to go for AJAX calls. A very simple implementation using fetch that doesn't require any additional packages (like jQuery) would look like this:
<script>
(function() {
document.getElementById({{worker.id}}).addEventListener('click', function(e) {
e.preventDefault();
fetch({{path('worker_edit', {'id': worker.id})}}, {method: 'POST'})
.then(function(response) {
// you can catch eventual errors here, and of course refresh your button or display a nice message..
});
});
})()
</script>
<table id="file_export" class="table table-striped table-bordered">
<thead>
<tr>
<th>ID</th>
<th>First Name</th>
<th>Last name</th>
<th>Active</th>
<th>edit</th>
</tr>
</thead>
<tbody>
{% for worker in workers %}
<tr>
<td>{{ worker.id }}</td>
<td>{{ worker.Firstname }}</td>
<td>{{ woker.Lastname }}</td>
<td>{{ worker.active ? 'active' : 'inactive' }}</td>
<td>
<i class="fa fa-pencil"></i>
</td>
</tr>
{% endfor %}
</tbody>
</table>
p.s: The javascript code above is not tested as I have to reproduce the twig and controller, but it could give you an idea on how to achieve the task.
Following the guide here
http://documentation.concrete5.org/developers/express/using-the-express-entry-block-to-output-entry-data
I am able to create the same results but if I change the example and attempt to use the attribute of an express object which is a file link or a date field the view block returns the following error
"Object of class DoctrineProxies__CG__\Concrete\Core\Entity\File\File could not be converted to string"
Can the below code be modified to resolve this or is this a core issue?
<?php defined('C5_EXECUTE') or die(_("Access Denied.")); ?>
<?php
if (isset($entry) && is_object($entry)) {
$drawings = $entry->getDrawings();
?>
<table id="datatable", class="table">
<thead>
<tr>
<th>Drawing Name</th>
<th>Drawing Number</th>
<th>Revision</th>
<th>Revision Date</th>
<th>Category</th>
<th>PDF</th>
</tr>
</thead>
<tbody>
<?php if (count($drawings)) {
foreach($drawings as $drawing) { ?>
<tr>
<td><?=$drawing->getDrawingName()?></td>
<td><?=$drawing->getDrawingNumber()?></td>
<td><?=$drawing->getRevision()?></td>
<td><?=$drawing->getDrawingRevisionDate()?></td>
<td><?=$drawing->getDrawingCategory()?></td>
<td><?=$drawing->getDrawingPdf()?></td>
</tr>
<?php } ?>
<?php } else { ?>
<tr>
<td colspan="6">No drawings found.</td>
</tr>
<?php } ?>
</tbody>
</table>
<?php } ?>
the problem comes from this line:
<?=$drawing->getDrawingPdf()?>
what getDrawingPdf() is returning is a file object so it cannot be output to the screen like a simple string. First, you would have to extract a string from it. For instance, the following code would extract the file name and show it.
<?php
$drawingPdf = $drawing->getDrawingPdf();
$pdfFileName = is_object($drawingPdf)? $drawingPdf->getFileName() : '';
?>
<td><?=$pdfFileName?></td>
What this code does is first get the file object which you already had in your code.
Then if we have a proper file object, get the file name. If it's not a proper file object (you never now it might have been deleted) we return and empty string.
And finally, we output our string $pdfFileName (which is either the filename or an empty string) in your table.
Hope this helps
Im creating an application un Symfony2.7 and I want to start creating reports, I have been reading for a couple of days and cant find a solution.
Ive tried ps pdfbundle, but I cant generate reports. Cant find more Documentation.
Please help
My Code:
public function formatoOcAction($id)
{
$facade = $this->get('ps_pdf.facade');
$response = new Response();
$em = $this->getDoctrine()->getManager();
$InOc = $em->getRepository('NivalInventarioBundle:InOrdenCompra')->findById($id);
$InOcDet = $em->getRepository('NivalInventarioBundle:InOrdenCompraDetalle')->findBy(array(
'idOrdenCompra' => $id));
$stylesheetXml = $this->renderView('NivalInventarioBundle:InOrdenCompra:ordencompra.xml.twig', array());
$this->render('NivalInventarioBundle:InOrdenCompra:ordencompra.pdf.twig', array(
"entities1" => $InOc,
"entities2" => $InOcDet,
"id" => $id),
$response);
$xml = $response->getContent();
$content = $facade->render($xml, $stylesheetXml);
$filename = $this->getParameter('upload_directory').'orden_compra_'.$id.'.pdf';
file_put_contents($filename, $content);
return new Response($content, 200, array('content-type' => 'application/pdf'));
}
Where $id is the Id of the purchase order.
This renders a xml file to PDF but without sylesheet.
This is the twig:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE pdf SYSTEM "%resources%/dtd/doctype.dtd">
{% set empresa = app.session.get('empresa') %}
<pdf>
<page>
<div>
<div>
<table>
<tr>
<td>
<h3>{{ empresa }}</h3>
</td>
<td id="s1">
<h2>Número: <b>{{ id }}</b></h2>
</td>
</tr>
<tr>
<td></td>
<td>
<h3>Orden de compra</h3>
</td>
</tr>
<tr>
<td></td>
<td>
Departamento de Finanzas
</td>
</tr>
</table>
</div>
<div>
{% for entity1 in entities1 %}
Fecha: {{ entity1.fecha|date('d-m-Y') }}
{% endfor %}
</div>
</div>
<div>
<div>
<table width="100%">

<td width="60%">Producto</td>
<td width="20%">Unidad</td>

{% set gran_total = 0 %}
{% for entity2 in entities2 %}

<td>{{ entity2.productoOc.nombre }}</td>
<td>{{ entity2.productoOc.unidadMedida.nombre }}</td>
<td class="text-right">{{ entity2.cantidad }}</td>
<td class="text-right">{{ entity2.precioCompra }}</td>
<td class="text-right">{{ entity2.total }}</td>
</tr>
{% set gran_total = gran_total + entity2.total %}
{% endfor %}
<tr>
<td></td><td></td><td></td><td></td>
<td class="text-right" >{{ gran_total|number_format(2) }}</td>
</tr>
</table>
</div>

Maybe look at the KnpSnappyBundle which allow you to generate PDF file from many sources, including twig templates : http://knpbundles.com/KnpLabs/KnpSnappyBundle
You have at least two options to choose from. I found easiest to work with:
Github KnpLabs/snappy as mentioned by Cyrille Hejl
PDF creator from html content, but in your report controller you would have to do all the work of creating:
header html from twig template
footer html from twig template
cover page html from twig template
toc XML from twig template
base document html from twig template
adding all mentioned html docs to object $pdf = $this->get('knp_snappy.pdf');
PROS:
easy to work with Twig html
no memory exhaust if entity object with relations is supplied to Twig (on longer documents)
CONS:
have to supply html files from Twig template for each joined page (cover, toc, header, footer, base doc)
needed tinkering with right wkhtmltopdf binary version
Github mbence/OpenTBSBundle
This is template merger. In your report controller you will have to supply office template and all the variables, that are replaced with TBS at e.g. word template:
it supports OpenOffice and MSOffice templates
PROS:
customer supplies template, you just replace dynamic content with variables (customer takes care of document design)
CONS:
it could run to memory exhaust problems, since PHP script holds all input variables or arrays in memory.
harder to understand than Twig html (longer learning curve)
I recommend to use: WhiteOctoberTCPDFBundle, it's a bundle to facilitate using TCPDF for PDF generation in Symfony2 applications, great to make the reports we need. Please go to: https://github.com/whiteoctober/WhiteOctoberTCPDFBundle
