Getting POST data from SELECT dropdown with variable value - php

Question

I need to create as many dropdowns as values from a database table query in worpress. I can't get post data to usermeta table from foreach dropdown list . This is the code:
$custom_posts_type = $wpdb->get_results("SELECT label,id FROM $table_name");
foreach ($custom_posts_type as $custom_post_type) {
$custom_post_type_name = $custom_post_type->label;
$custom_post_type_id = $custom_post_type->id;
?>
<p>
<label for="dropdown">Permisos de usuario para <?php echo $custom_post_type_name;?>: </label>
<?php
$user_custom_post = 'user_custom_' . $custom_post_type_name;
$selected = get_the_author_meta( $user_custom_post, $user->ID );
$post_type_object = get_post_type_object($custom_post_type_name);
$label = $post_type_object->label;
$posts = get_posts(array('post_type'=> $custom_post_type_name, 'post_status'=> 'publish', 'suppress_filters' => false, 'posts_per_page'=>-1));
echo '<select name="' . $user_custom_post . '" id="' . $user_custom_post . '">';
?>
<option value="all" <?php selected( $user_custom_post[0], "all" ); ?>>All <?php echo $label;?></option>
<?php
foreach ($posts as $post) {
echo '<option value="', $post->ID, '"', $selected == $post->ID ? ' selected="selected"' : '', '>', $post->post_title, '</option>';
}?>
<?php
echo '</select>';
?>
</p>
<?php
update_user_meta( $user->ID, $user_custom_post, $_POST[$user_custom_post] );
} //endforeach
I appreciate your help.

Probably... I have created two functions without foreach. And, if I don't use variables it works:
add_action( 'show_user_profile', 'pglr_user_pages' );
add_action( 'edit_user_profile', 'pglr_user_pages' );
add_action( 'user_register', 'pglr_user_pages' );
function pglr_user_pages( $user ) {
$post_type = "page"; ?>
<p>
<label for="dropdown">Asignar <?php echo $post_type;?>: </label>
<?php
$selected = get_the_author_meta( 'user_custom_page', $user->ID );
$post_type_object = get_post_type_object($post_type);
$label = $post_type_object->label;
$posts = get_posts(array('post_type'=> $post_type, 'post_status'=> 'publish', 'suppress_filters' => false, 'posts_per_page'=>-1));
echo '<select name="user_custom_page_value" id="user_custom_page_value">';
?>
<option value="all" <?php selected( '', "all" ); ?>>All <?php echo $label;?></option>
<?php
foreach ($posts as $post) {
echo '<option value="', $post->ID, '"', $selected == $post->ID ? ' selected="selected"' : '', '>', $post->post_title, '</option>';
}?>
<?php
echo '</select>';
?>
</p>
<?php
}
add_action( 'personal_options_update', 'save_pglr_user_pages' );
add_action( 'edit_user_profile_update', 'save_pglr_user_pages' );
function save_pglr_user_pages( $user_id ) {
if ( !current_user_can( 'edit_user', $user_id ) )
return false;
//save dropdown
update_usermeta( $user_id, 'user_custom_page', $_POST['user_custom_page_value'] );
}
However, this code doesn't work:
add_action( 'show_user_profile', 'pglr_user_pages' );
add_action( 'edit_user_profile', 'pglr_user_pages' );
add_action( 'user_register', 'pglr_user_pages' );
function pglr_user_pages( $user ) {
$post_type = "page"; ?>
<p>
<label for="dropdown">Asignar <?php echo $post_type;?>: </label>
<?php
**global $user_custom_post;**
**$user_custom_post = 'user_custom_' . $post_type;**
$selected = get_the_author_meta( **$user_custom_post**, $user->ID );
$post_type_object = get_post_type_object($post_type);
$label = $post_type_object->label;
$posts = get_posts(array('post_type'=> $post_type, 'post_status'=> 'publish', 'suppress_filters' => false, 'posts_per_page'=>-1));
echo '<select name="user_custom_page_value" id="user_custom_page_value">';
?>
<option value="all" <?php selected( '', "all" ); ?>>All <?php echo $label;?></option>
<?php
foreach ($posts as $post) {
echo '<option value="', $post->ID, '"', $selected == $post->ID ? ' selected="selected"' : '', '>', $post->post_title, '</option>';
}?>
<?php
echo '</select>';
?>
</p>
<?php
}
add_action( 'personal_options_update', 'save_pglr_user_pages' );
add_action( 'edit_user_profile_update', 'save_pglr_user_pages' );
function save_pglr_user_pages( $user_id ) {
if ( !current_user_can( 'edit_user', $user_id ) )
return false;
//save dropdown
update_usermeta( $user_id, **$user_custom_post,** $_POST['user_custom_page_value'] );
}
The problem may be using variables...
