Variable transfer for loop to loop, or data error

Question

I’m here for one thing right now that has an array called dayinfo. In which I want to name the item number, the item number can be found in the variable fixed interval.date_id. Do you know a solution for transferring data in the forban in this way? Although the problem may arise elsewhere in the code

My twig code:

   {% for fixintervall in days %}
        <tr>
            <th><p>
                {{ fixintervall.start_day  }}
                </p></th>

    {% for dayinfo in daysinfo %}
        {% for dayinfoti in dayinfo..fixintervall.date_id %}
            {% for dayin in dayinfoti %}
            <p>
                {{ dayin.start }} - {{ dayin.start2 }}
            </p>
            {% endfor %}
        {% endfor %}
    {% endfor %}

            <br>

        </tr>
        <br>
    {% else %}

Controller Code:

 #[Route('/cons/show/{id}', name: 'user_cons_show', methods: ['GET'])]
    public function show($id, ConsRepository $consRepository): Response
    {
        $showcon = array();
        $showconsintervall = array();
        $days = array();
        $dayid = array();
        $daysinfo = array();



        $con = $consRepository->find($id);
        $showconsintervall = $con->getIntervalls();

       foreach ($showconsintervall as $ex){
            $datumid = $ex->getId();
            $kezdodatum = $ex->getStart();
            $vegdatum = $ex->getEnd();
            $morepeople = $ex->getMore();
            $freetime = $ex->getFreeTime();
            $constime = $ex->getConsTime();
            $consulid = $id;

            /* Array in belüli array a cél az időpont listázás miatt */

            while($kezdodatum <= $vegdatum) {
                date_default_timezone_set($kezdodatum->getTimezone()->getName());
                if (date("Y-m-d",$kezdodatum->getTimestamp()) >= date('Y-m-d'))
                {
                    array_push(
                        $days, [
                        "start_day" => date("Y-m-d",$kezdodatum->getTimestamp()),
                        "date_id" => $datumid,
                    ]);

                    //logikai bukfenc

                    $start_a = date("H:i",$kezdodatum->getTimestamp());
                    $end_a = date("H:i",$vegdatum->getTimestamp());
                    $dat_a =  date("H:i",$constime->getTimestamp());
                    $up_a = date("H:i",$freetime->getTimestamp());


                    if (!array_key_exists($datumid, $daysinfo)){

                        $start = $start_a;
                        $end = $end_a;
                        $dat =  $dat_a;
                        $up = $up_a;
                        $start2 = $start;


                        $x = $datumid;
                        $x_data = array();

                       // echo "<br><br><br>Info:". $start2 ." - ". $end."<br>";
                        while ($start2 <= $end)
                        {


                            $start2_noft = (strtotime($start) + (strtotime($dat)) - strtotime('00:00:00'));
                            $start2 = date("H:i", $start2_noft);
                           // echo "Eleje:".$start." ".$start2." <br>";

                            if ($start2 <= $end){
                                array_push(
                                    $x_data,[
                                    "start" => $start,
                                    "start2" => $start2,
                                ]);
                            }

                            $start_noft = strtotime($start2) + strtotime($up) - strtotime('00:00:00');
                            $start = date("H:i", $start_noft);
                           // echo "Vége:".$start." ".$start2." <br>";
                        }

                        array_push(
                            $daysinfo,[
                            $x => $x_data
                        ]);
                    }
                }
                    $kezdodatum->modify('+1 day');
                }

            }


        array_push(
            $showcon, [
            "user_id" => $con->getUserId()->getId(),
            "cons_id" => $id,
        ]);

       print_r($daysinfo);

        return $this->render('user/cons_show.html.twig', [
            'controller_name' => 'Consulens',
            'showcon' => $showcon,
            'days' => $days,
            'dayid' => $dayid,
            'daysinfo' => $daysinfo,
        ]);
    }

And the problem is, after all, that the data does not appear. At least the intervals are not

before using the twig format, try to use standard PHP code to traverse the data. — zimorok

The structure {% for x in y..z %} is used to loop over a sequence of numbers/letters as seen in the documentation

This will generate/compile to something like

<?php
    for($x = $y; $x < $z; $x++) {
        echo $x;
    }

As you didn't provide much information about the array dayinfoti I'll assume the keys of dayinfoti will match fixintervall.date_id. If this is the case then you can just use this variable as the key of the array as you would do in PHP

{% for fixintervall in days %}
    ...
    ....
    {% for data in dayinfo[fixintervall.date_id]|default([]) %}
        ...
        ...
    {% endfor %}
{% endfor %}

The default filter will account for missing elements in the dayinfo
Basically, this removes the need to test if the key fixintervall.date_id isset in the array dayinfo before looping it

More about dynamic keys/variables

Hi, don't be mad we can misunderstand each other but how would it help me to list the start and end dates below the date?

DarkBee Over a year ago

I mean, doesn't this help you? Please provide the data inside both variables then
