WordPress : Comment passer des variables d’une fonction à une autre ou combiner des fonctions

J’ai deux fonctions :

• 1er – Prend en charge toutes les options de personnalisation
• 2nd – Génère un style en ligne à partir de ces options

Dans la première fonction, je définis des variables à partir desquelles je crée des paramètres de personnalisation et des contrôles comme ceci :

function im_customize_register( $wp_customize ) {

//Custom Sections

$wp_customize->add_section(
    'body',
    array(
        'title'     => __('Body Settings', 'impressive'),
        'priority'  => 200
    )
);

//Styles

$bg_color = 'background-color:';
$max_width = 'max-width:';

$styles = array();

$styles[] = array(
  'slug'=>'body_bcolor',
  'default' => "#F1F2F1",
  'label' => __('Body Background Color', 'impressive'),
  'css_class' => 'body',
  'attribute' => $bg_color,
  'section' => 'body',
  'type' => 'color'
);
$styles[] = array(
  'slug'=>'max_container_width',
  'default' => '1440',
  'label' => __('Maximal Container Width', 'impressive'),
  'css_class' => '.header',
  'attribute' => $max_width,
  'section' => 'body',
  'type' => 'number'
);

foreach( $styles as $style ) {

  $wp_customize->add_setting(
    $style['slug'], array(
      'default' => $style['default'],
      'type' => 'option',
      'capability' =>
      'edit_theme_options'
    )
  );

 if ( $style['type'] == 'color' ) {
  $wp_customize->add_control(
    new WP_Customize_Color_Control(
      $wp_customize,
      $style['slug'],
      array('label' => $style['label'],
      'section' => $style['section'],
      'settings' => $style['slug'],
      'type' => $style['type'])
    )
  );
  } elseif ( $style['type'] == 'image' && $style['section'] == 'header_image' ) {
    $wp_customize->add_control(
        new WP_Customize_Header_Image_Control(
        $wp_customize,
        $style['slug'],
        array('section' => $style['section'],
        'settings' => $style['slug'])
    )
  );
 } else {
  $wp_customize->add_control(
    new WP_Customize_Control(
      $wp_customize,
      $style['slug'],
      array('label' => $style['label'],
      'section' => $style['section'],
      'settings' => $style['slug'],
      'type' => $style['type'])
    )
  );

  }

}

}
add_action( 'customize_register', 'im_customize_register' );

Dans la deuxième fonction, je dois taper les mêmes variables pour que le script génère du CSS en ligne :

function im_custom_style_create() {

wp_enqueue_style( 'im_custom_style', get_template_directory_uri() . '/css/im_custom_style.css' );

$custom_css = '';

$bg_color = 'background-color:';
$max_width = 'max-width:';

$measurement_unit = '';

$styles = array();

$styles[] = array(
  'slug'=>'body_bcolor',
  'default' => "#F1F2F1",
  'label' => __('Body Background Color', 'impressive'),
  'css_class' => 'body',
  'attribute' => $bg_color,
  'section' => 'body',
  'type' => 'color'
);
$styles[] = array(
  'slug'=>'max_container_width',
  'default' => '1440',
  'label' => __('Maximal Container Width', 'impressive'),
  'css_class' => '.header',
  'attribute' => $max_width,
  'section' => 'body',
  'type' => 'number'
);

foreach( $styles as $style ) {

if ( $style['attribute'] == $max_width ) { $measurement_unit = 'px'; }

if ( get_option( $style['slug'] ) == true ) { $custom_css = '' . $style['css_class'] . ' { ' . $style['attribute'] . ' ' . get_option( $style['slug'] ) . $measurement_unit . '; } '; };

wp_add_inline_style ('im_custom_style', $custom_css);
}

}
add_action( 'wp_enqueue_scripts', 'im_custom_style_create' );

Ma question est la suivante: existe-t-il un moyen de passer $stylesde la 1ère fonction à la 2ème ou s’il n’y en a pas, je peux combiner ces deux fonctions. J’ai essayé de les combiner, mais je n’ai pas pu faire en sorte que la magie opère.

Solution n°1 trouvée

Il y a 2 façons qui seraient les plus simples.

1. Faites-le avec un appel de fonction.

2. Rendre les variables globales.

Le premier se ferait ainsi :

function my_func() {
    $styles = 'stuff';

    second_func($styles);
}

function second_func($styles) {
    // do something with $styles
    var_dump($styles);
}

La deuxième façon serait faite comme ceci:

// Set global variable
$GLOBALS['styles'] = 'stuff';


// Call it anywhere else
global $styles;

Pour en savoir plus sur les variables globales : http://php.net/manual/en/language.variables.scope.php

EDIT : Voir ci-dessous.

global $styles;

$styles = array(
  array(
    'slug'=>'body_bcolor',
    'default' => "#F1F2F1",
    'label' => __('Body Background Color', 'impressive'),
    'css_class' => 'body',
    'attribute' => 'background-color:',
    'section' => 'body',
    'type' => 'color'
  ),
  array(
  'slug'=>'max_container_width',
  'default' => '1440',
  'label' => __('Maximal Container Width', 'impressive'),
  'css_class' => '.header',
  'attribute' => 'max-width:',
  'section' => 'body',
  'type' => 'number'
  )
);


function im_customize_register( $wp_customize ) {
global $styles;
//Custom Sections

$wp_customize->add_section(
    'body',
    array(
        'title'     => __('Body Settings', 'impressive'),
        'priority'  => 200
    )
);

foreach( $GLOBALS['styles'] as $style ) {

  $wp_customize->add_setting(
    $style['slug'], array(
      'default' => $style['default'],
      'type' => 'option',
      'capability' =>
      'edit_theme_options'
    )
  );

 if ( $style['type'] == 'color' ) {
  $wp_customize->add_control(
    new WP_Customize_Color_Control(
      $wp_customize,
      $style['slug'],
      array('label' => $style['label'],
      'section' => $style['section'],
      'settings' => $style['slug'],

  } elseif ( $style['type'] == 'image' && $style['section'] == 'header_image' ) {

        array('section' => $style['section'],
        'settings' => $style['slug'])
    )
  );
 } else {
  $wp_customize->add_control(

      'section' => $style['section'],

    )
  );

  }
