I have created a couple of website using CI 3.1.1 (PHP)
And none of them is being indexed on google even after all the tips and trick have been implicated which were suggested by google.
Is there anything in the code itself which could be the reason and not allowing google to index my pages.
Any help would be appreciated.
Thank You
I got Users, Absences and Reasons tables:
Users
id | name
Absences
id | user_id:foreignKey | reason_id:foreignKey | deputy_id:foreignKey | start:date | end:date
Reasons
id | name
I got attendance calendar which looks like:
Day | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
-----------------------------------------------|
User1 | o | o | V | V | S | S | o | o | o | V |
-----------------------------------------------|
User2 | T | o | o | o | H | V | o | V | o | V |
-----------------------------------------------|
Where “V” is Vacation, “S” sick etc. I want to print each User attendance report in that table.
@foreach ($users as $user )
<tr>
<td> {{ $user->name }} </td>
@if($user->absences != null)
@foreach($days as $day)
@foreach ($user->absences as $absence)
@if($day >= $absence->start->format('d') && $day <= $absence->end->format('d'))
// there check if $user->absence->reason_id == something ...
@else
@endif
@endforeach
@endforeach
@endif
</tr>
@endforeach
Also I want to have a tooltip, where I print specific data for each day (reason name, deputy name).
I have no idea how to get the range between two dates in each absence, merge it to got f.e table of user absence days with another array with reason.:
[
2 => ['reason_id => 1, deputy_id = 3],
3 => ['reason_id => 1, deputy_id = 3],
7 => ['reason_id => 2, deputy_id = 1]
]
Where keys [2,3,7] are the days of the absence.
Is there easier way to achieve that or should I rebuild the database structure?
If I add the following line into the template the checkout becomes unavailable.
"n<img src="https://example.com/images/girocode.png" alt="GiroCode" />" .
How can I make the work in PHP?
next block is located in class that inherits database class,connect() is my method for connecting to a database
protected function checkUser($username){
$searchForUser=$this->connect()->prepare('select username from users where username=?;');
if($searchForUser->execute(array($username))){
$searchForUser=null;
header("location: ../login.php?error=existing_username");
exit();
}
$check=false;
if($searchForUser->rowCount()>0){
$check=true;
}
return $check;
}
next block is from class that inherits a class above
private function checkForUserExistance(){
$value = false;
if($this->checkUser($this->username)){
$value=true;
}
return $value;
}
I develop a forum module for a web site IN LARAVEL 8, I face the problem of Undefined property: AppModelsThread::$title, since 3 days I look for the solution but in vain.
Here is the code of my model
<?php

use AppTraitsHasTags;
use IlluminateDatabaseEloquentBuilder;
use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateDatabaseEloquentModel;
use IlluminateDatabaseEloquentRelationsBelongsTo;

use HasAuthor;
use HasFactory;
const TABLE = 'threads';
protected $table = self::TABLE;
protected $fillable = [
'title',
'body',
'slug',
'writer_id',
'category_id',
];
protected $with = [
'category',
'writer',
'tags',];
public function category(): BelongsTo
{
return $this->belongsTo(Category::class);
}
public function excerpt(int $limit = 250): string
{
return Str::limit(strip_tags($this->body()), $limit);
}
public function id(): int
{
return $this->id;
}
public function title(): string

}
public function scopeForTag(Builder $query, string $tag): Builder
{
return $query->whereHas('tagsRelation', function ($query) use ($tag) {
$query->where('tags.slug', $tag);
});
}
code of my Controller that displays the details of the post (show)
public function show(Category $category, Thread $thread)
{
return view('pages.threads.show', compact('thread', 'category'));
}

thank you for your help
I was asking myself if it was a bad practice to send every ajax request I use on my Laravel 8 project with the HTTP Post method.
What I mean is that, according to Laravel 8 documentation on routing (if I understood everything well), you should use the appropriate HTTP request :
Route::get($uri, $callback);
Route::post($uri, $callback);
Route::put($uri, $callback);
Route::patch($uri, $callback);
Route::delete($uri, $callback);
Route::options($uri, $callback);
A French tutorial on the routes explains this (translated by myself) :
GET : ask for a resource that never changes,
POST : update or create a resource (often wrongly used when PUT is needed),
PUT : create or replace a resource,
PATCH : partialy update a resource,
DELETE : delete a resource.
The “problem”, if there is one, is that in my code in almost only use HTTP post requests for AJAX in my routes/web.php file, like this :
Route::post('mails/update/{id}', 'AppHttpControllersMailController@update');
Route::post('mails/sendMail/', 'AppHttpControllersMailController@sendMailTest')->name('mails.sendMailTest');
Route::post('mails/sendInstantMail/', 'AppHttpControllersMailController@sendInstantMail')->name('mails.sendInstantMail');
Route::post('mails/getRouteList/', 'AppHttpControllersMailController@getRouteList')->name('mails.getRouteList');
According to what I read, I should probably use PUT or PATCH for my update method. But with POST it works. Is it a bad practice to continue to use POST?
If I guess right, AJAX is only a way to do HTTP request, but in fact it is still the same idea behind the request, so I should change my request methods.
I am really sorry if my question is dumb, and thanks for your help!

I have a view in my Laravel project and I just want to import some sections from other blades but with different css .
Can anyone help?
I am making a setting in my WooCommerce website where the user can choose between a table view and a grid view of the products. I use cookies for this. The setting works sometimes when clicking on it; but when changing page, when there is pagination, it doesn’t always retain the selected view.
I set the cookie like this:
document.cookie = "Techsaker_se_vyval=Rutnätsvy";
And then, in my content-product.php file I check it like this:
// If products view not set to grid, show table view
if (($_COOKIE['Techsaker_se_vyval']) != 'Rutnätsvy') {
It seems the cookie value isn’t retained.
Additionally, it will sometimes also show the table view on one page of a product category, and then the grid view on a different page.
I have also observed that if I print the cookie value to the console with console.log, the value is often different from when I print it from the php with:
var_dump($_COOKIE['Techsaker_se_vyval']);
For example when I tested this, they showed conflicting values on page 1 of my shop startpage and the same values on page/2/. And I could only change the value successfully on page 2.
After further tests, I observed that the JavaScript and php sometimes do show the same value also on page 1, but even then, I couldn’t change the view on page 1. On clicking on an option, the JavaScript value in the console sometimes changes without changing the view printed, sometimes not even that. However; in a product category, as opposed to the shop startpage, I have seen that sometimes I can change the view on both page 1 and page 2.
It’s always the php value that determines what view is output. Why isn’t it always registering the same value as the JavaScript?
And changing the view always seems to work when it’s on page 2.
Does anyone know why this could be happening?
Thank you!
In php the following code throws error:
if($x = 1 && $x == 1)
I’ve been told, it’s because && has higher precedence than =, which cases the expression to get converted to:
if($x = (1 && ($x == 1)))
So far so good, but now consider:
if $x=1; ($x == 1 && $x = 2)
This doesn’t throw error. Why doesn’t it get converted to:
if $x=1; (($x == 1) && $x) = 2)
I’ve been told thats due to = being right assosiative, but https://www.php.net/manual/en/language.operators.precedence.php says When operators have equal precedence their associativity decides how the operators are grouped.. Here we have =, && and == all being of different precedence.
P.S; My actual code is if($result != false && $res = $stmt->get_result()), which has been copied from some other reputable source, so seems like not using unneeded parenthesis is common in php.
The ones checked are the correct answer to the question. But when I click on the submit button, the questions changes and state the answers are wrong. I’ve tried too fix it by using the GET method. But that didn’t work either.
The result I am trying to get it have 3 random questions. Which are stored in an array with it’s options and answer. When the 3 questions are displayed, the options will be displayed with it. When the user clicks on the correct answer it should display the correct result, but it is not able to at the moment.
Let me include the code below.
<?php
/*-----------------------------------Generate 3 Random Questions ----------------------------------------- */
/*Array Random Function*/
$pickqns_key = array_rand($qnPool,3);
//var_dump($pickqns_key); ----- Test if Array is sucessfully randomise with 3 questions
/*Store 3 Question into an Array using the key generated*/
$qns_3 = array();
$i = 0;
foreach($pickqns_key as $key){
$qns_3[$i] = $qnPool[$key];
$i++;
}
/*Individual Question List*/
$question1 = $qns_3[0]["qns"];
$q1option1 = $qns_3[0]["ops"][0];
$q1option2 = $qns_3[0]["ops"][1];
$q1option3 = $qns_3[0]["ops"][2];
$q1ans = $qns_3[0]["ans"];
var_dump($qns_3[0]);
var_dump($q1ans);
$question2 = $qns_3[1]["qns"];
$q2option1 = $qns_3[1]["ops"][0];
$q2option2 = $qns_3[1]["ops"][1];
$q2option3 = $qns_3[1]["ops"][2];
$q2ans = $qns_3[1]["ans"];
var_dump($qns_3[1]);
var_dump($q2ans);
$question3 = $qns_3[2]["qns"];
$q3option1 = $qns_3[2]["ops"][0];
$q3option2 = $qns_3[2]["ops"][1];
$q3option3 = $qns_3[2]["ops"][2];
$q3ans = $qns_3[2]["ans"];
var_dump($qns_3[2]);
var_dump($q3ans);

</div>I’m new to Laravel and I’m trying to protect some file downloads trough Laravel.
All I’ve read about it is about sending files as “blob” but this solution has issues when I download Blob in my React App: some files stop the download before the entire file is received.
The methode I used
return response()->download($file, 'Test File', $headers, 'inline');
Thanks for the help
I have a system that should forward incomming SMS to email. (Currently the script just forwards the file as is… Not very elegant.)
This system deals with a text file with multiple lines. I read it with file() directly into an array. The top few lines have a format as below, and I want to pick some parts out and format them into the email. The message is at the bottom of this text file, and may be over several line including blank ones.
How do I merge just the last few parts (message lines) of the array not knowing the number of lines that it has in total? I think I know which line to start at…

I have page arrows (Previous and Next ) on every single post however when I reach the last post I want to still keep the Next button which will link to the first post and vice versa if I’m on the first post I want to keep the previous button which would link to last post.
This is my .twig file which currently simply navigates to next or previous post if there is one.

I am writing a php program that takes URL as input from the users and finds out the dead links from that webpage of the URL. Sometimes, if the webpage is too big then my execution speed of the program takes some more time. So how can I make a dynamic interface like loading (until the data program is fully executed)?
I have a strange problem in a symfony 5.3.10 app and i can’t wrap my head around it.
If i trigger a 500 error, like so:
/**
* @Route("/", name="pvr_index", methods={"GET"})
*/
public function index(): Response
{
echo $a;
Where $a is not defined, in dev environment i get a nice error page.
I’d expect that in prod i would get a not so nice error page that just tells me that i have a 500 error. And this would happen correctly until some time ago, when something changed, but i don’t know what.
Now instead i get no error, not even in the symfony server console, and the script execution would keep on going like nothing happened.
What i tried:
Adding the supposed exception inside a try/catch:
try {
echo $a;
}
catch (Exception $e)
{
dump($e);
die();
}
Nothing happens, the catch isn’t triggered.
Creating an exception listener:
In services.yaml i have:
exception_listener:
class: AppEventExceptionListener
tags:
- { name: kernel.event_listener, event: kernel.exception }
And in ExceptionListener.php i have:
class ExceptionListener
{
public function __construct(Environment $engine) {
$this->engine = $engine;
}
public function onKernelException(ExceptionEvent $event)
{
dd($event->getThrowable()->getMessage());
}
}
Still nothing happens, the listener isn’t triggered.
Everything works as expected in dev environment, the problem presents itself only in prod.
Looking at a phpinfo(); page i see that the error reporting is enabled, so i think that the problem lies in the symfony configuration.
I’m using php 7.4 and have no real access to the php.ini file
