Question

I'm new to developing plugins for WordPress, I've been doing it for Magento 2 and thought it would be similar, so here I am.

I'm consuming a RESTful API to display information about some courses, it retrieves me the info on all courses so now I have to filter some attributes, for example "city", for this my user has an HTML form to select which city he is in, but when I try to use the "city" field from the form it returns as null, it doesn't matter if I use post or get method.

Which one is the correct form of getting this attributes in WordPress?

this is an example of the form page:

    <?php
/* 
 * Formulario de filtros
 */
// create curl resource

require_once('../../../../wp-config.php');

$ciudad = $_POST['ciudad'];

var_dump($ciudad);

$accessToken = '---';
$apiUrl = 'url';

$curl = curl_init($apiUrl);
curl_setopt($curl, CURLOPT_HTTPHEADER, ['Authorization: Bearer '.$accessToken]);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$json = curl_exec($curl);
$cursos = json_decode($json);
$arr = 0;

foreach($cursos as $k => $cur)
{
    $sede = $cur->Sede;
    if($sede === 'MEDELLIN' ){
    $codigo[] = substr($cur->Programa, 0, 4);
    $programa[] = $cur->Programa;
    $precio[] = $cur->Valor_Contado;
    }
}
$cod = array_unique($codigo);
var_dump($cod);
foreach ($cod as $c){
    echo "Programa: ".$c."<br>";
}

?>

Answer 1

经过研究并尝试了几种方法，我在自定义插件的主PHP文件中一起尝试了所有代码，而不是使用require_once。

我有了下一个结构： wp-content >> plugins >> myplugin >> myplugin.php

并且在所说的php文件中有一个require_once用于： wp-content >> plugins >> myplugin >> php >> form.php

似乎您不能在主要php文件之外的文件中使用$ _POST，$ _ GET或evev cookie，因此我不得不在其中处理所有代码，而忘了mu php文件夹和eny MVC结构。
