[英]Get values from select2 with php without jquery
I have a registration system where there are several fields.我有一个注册系统,其中有几个字段。 One of the registration fields is Segments and they come from the database:注册字段之一是 Segments,它们来自数据库:
public function comboSegmentos($key)
{
$sqlMostrar = mysqli_query($this->conexao, "SELECT * FROM loja_segmentos;");
if (mysqli_num_rows($sqlMostrar) == 0)
{
$mostrar = "<div style='color: red'>Nenhuma segmento cadastrado até o momento.</div>";
}
else
{
$mostrar = "<select name='Segments[]' id='segmentos' class='form-control select2' multiple='multiple' style='width: 35%'>";
while ($jmMostrar = mysqli_fetch_object($sqlMostrar))
{
$mostrar .= "<option value='".$jmMostrar->Segmentos."' ".$selected.">".$jmMostrar->Segmentos."</option>";
}
$mostrar .= "</select>";
}
return $mostrar;
}
So that the method doesn't have too many parameters, I did it like this:为了使该方法没有太多参数,我这样做了:
<?php
...
$dados = array_filter($_POST);
echo $metodos->cadastrarProdutos($dados);
Method cadastrarProdutos($dados)方法 cadastrarProdutos($dados)
But I'm not able to get the values of the Segments even using foreach().但即使使用 foreach(),我也无法获得段的值。
<?php
public function cadastrarProdutos(array $dados)
{
...
$segments = $dados["Segments"];
foreach($segments as $seg)
{
$segm = $seg;
}
...
}
How can I get the values of the select2 field and get them using a PHP method without Jquery?如何获取 select2 字段的值并使用没有 Jquery 的 PHP 方法获取它们?
I managed to solve it as follows:我设法解决它如下:
<?php
public function cadastrarProdutos(array $dados)
{
...
$segments = $dados["Segments"];
$segm = array();
foreach($segments as $seg)
{
$segm[] = $seg;
}
$segments = implode(',',$segm);
...
}
