maber03's questions

I am doing an article with two columns in Latex and in the Appendices instead of putting the title and then the image, 2 titles are put on one page and then the images on the others. It is not a problem of sizes because I have tried with everything and nothing, also specifying [h!] and [htb]. I attach photos of how it is now and how I would like it to be (marked in red in the image):

Title page only:

Image only page:

Any ideas?

I am trying to send the data to the backend when submitting a form so that I can create a new stay in the database.

The thing is that it doesn't give me any errors, and it shows me the alert that it has been done correctly, but it isn't created in the database, I don't know if I'm not treating the data well in the controller or how, the query works correctly because I have tried to add the stay in a hardcoded way and it works.

The form is as follows:

<form id="formCountry">
                <div class="modal fade" id="addPaisModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
                    <div class="modal-dialog" role="document">
                        <div class="modal-content">
                            <div class="modal-header">
                                <h5 class="modal-title" id="exampleModalLabel">Afegeix País</h5>
                                <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                                    <span aria-hidden="true">&times;</span>
                                </button>
                            </div>

                                <div class="modal-body">
                                    <div class="form-group">
                                        <label for="agreementCode">Nom</label>
                                        <input type="text" name="nomPais" class="form-control" id="nomPais" placeholder="Nom país">
                                    </div>
                                    <div class="form-group">
                                        <label for="agreementStudies">Programa</label>
                                        <select name="programaPais" class="form-control" id="programaPais">
                                            <?php foreach ($programs as $program): ?>
                                                <option>
                                                    <?php echo $program->codiPrograma;?>
                                                </option>
                                            <?php endforeach;?>
                                        </select>
                                    </div>

                                </div>
                                <div class="modal-footer">
                                    <button type="button" class="btn btn-secondary">Tanca</button>
                                    <button type="submit" name="submit" value="Submit" id="addCountry" class="btn btn-primary">Guarda</button>
                                </div>

                        </div>
                    </div>
                </div>
            </form>

When I hit the submit button through jquery I send it by post to the backend (the 2 alerts show me the values ​​correctly):

$(document).on("submit", "#formCountry", function(e) {
   e.preventDefault();
    var data = new FormData;
    data.append("programaPais", $("#programaPais").val());
    data.append("nomPais", $("#nomPais").val());
    alert($("#programaPais").val());
    alert( $("#nomPais").val());


    $.ajax({
        type: "POST",
        url: "admin.php/updateTableCountries",
        data: data,
        processData: false,
        contentType: false,
        success:function(t,e,c){
            alert("Pais creat correctament!");
            $("#addPaisModal").modal('hide');

        },
        error: function(e, a, t) {alert("Error al crear el pais!");}
    });
})

Controller (I follow MVC architecture):

 case 'updateTableCountries':
            $data= $_POST['data'];
            array_push($parameters, $data);
            $actionName = $controller;
            break;

Function:

public function updateTableCountries($parameters){
    require 'models/CountriesModel.php';
    $countriesModel = new CountriesModel();

    $data = $parameters[0];

    $countriesModel->addCountry($data['programaPais'],$data['nomPais']);

    $countriesModel->disconnect();
}

Query:

public function addCountry($codiPrograma,$nomPais){
    try {
        $consulta = $this->db->prepare("INSERT INTO pais(codiPrograma,nomPais) VALUES (?,?)");
        $consulta->execute(array($codiPrograma,$nomPais));

    } catch (Exception $e) {
        $obj = $e;
    }

}

Any idea what can happen?

I need to verify that all the URLs that I have saved in a DB (mysql) work and do not return Error 404 when clicking on them in the different places where they appear on my website. Once verified, all those that do not work will be displayed on the web screen and the place on the web where they are located in order to eliminate them.

For this I have a script in PHP that when the user on the web launches test, it takes about 10 minutes to be able to return the result of all the URLs that do not work, so I would need to be able to execute this process in the background and go saving the results in some other table of the BD.

Right now what I'm doing is getting the URLs from the DB (from 4 different tables) and doing a foreach for each type (I'm attaching a snippet):

    $urlsUniversitat = $universitiesModel->getURLUniversities();
    $urlsFooter = $adminManagmentModel->getURLSubsection();
    $urlsAssignaturesExternes = $acordsModel->getURLsAcords();
    $urlAssignaturesUAB = $assignaturesModel->getURLAssignatures();

    $failedURLS = array();

    //Modificamos el time limit para que no pete
    set_time_limit(200000);

    $options = array(CURLOPT_RETURNTRANSFER => true, CURLOPT_SSL_VERIFYPEER => false, CURLOPT_FOLLOWLOCATION => true);


    //URLS Unis
    foreach ($urlsUniversitat as $urlUni){
        $urlPrincipal = $urlUni['urlUniversitat'];
        $handleURLPrincipal = curl_init($urlPrincipal);
        curl_setopt_array($handleURLPrincipal, $options);
        $responsePrincipal = curl_exec($handleURLPrincipal);
        $urlHeaderPrincipal = curl_getinfo($handleURLPrincipal, CURLINFO_HTTP_CODE);

        $urlIntercanvi = $urlUni['urlIntercanvis'];
        $handleURLIntercanvi = curl_init($urlIntercanvi);
        curl_setopt_array($handleURLIntercanvi, $options);
        $responseIntercanvi = curl_exec($handleURLIntercanvi);
        $urlHeaderIntercanvi = curl_getinfo($handleURLIntercanvi, CURLINFO_HTTP_CODE);

        if ($urlHeaderPrincipal == 404 || $urlHeaderPrincipal == 0){
            array_push($failedURLS, array('modul' => "URL Universitat",'redirect' => $urlUni['idUniversitat'], 'url' => $urlPrincipal));
        }

        if ($urlHeaderIntercanvi == 404 || $urlHeaderIntercanvi == 0){
            array_push($failedURLS, array('modul' => "URL Intercanvi", 'redirect' => $urlUni['idUniversitat'], 'url' => $urlIntercanvi));
        }

        curl_close($handleURLPrincipal);
        curl_close($handleURLIntercanvi);
    }

    //URLS Footer
    foreach ($urlsFooter as $url){

        $urlPrincipal = $url['urlApartat'];
        $handler = curl_init($urlPrincipal);
        curl_setopt_array($handler, $options);
        $response = curl_exec($handler);
        $urlHeader = curl_getinfo($handler, CURLINFO_HTTP_CODE);

        if ($urlHeader == 404 || $urlHeader == 0){
            array_push($failedURLS, array('modul' => "Footer", 'redirect' => $url['titolApartat'], 'url' => $urlPrincipal));
        }

        curl_close($handler);
    }

The idea would be that when saving the result of the process that runs in the background in the DB, it can then show on the screen the time and day in which the test and the results have been done, as well as being able to run it again.

I'm pretty new to the whole web theme and PHP and I can't think of how I could run this in the background or with what tool to do it, could you give me some advice?

I have an activity (main activity) with a Start button and a floating actin button (the +), this activity has a menu and each of the sections are fragments. The thing is that in all the fragments of this activity I get that button and I can't delete it. I have tried to change the xml for FrameLayout but nothing. It is as if it has a transparent background, although it has a white background set. I'm pretty new to this and I don't know what else to try. Any ideas?
