Wordpress中使用的PHP foreach循环wp_customize->；添加\u控件

我正试图在WordPress定制程序的下拉列表中列出要使用的Google字体选择，但我很难正确执行此循环：

$i = 0;
foreach ($items as $font_value => $item) {
    $i++;
    $str = $item['family'];
}

上面的字符串需要在下面的数组中才能生成选项列表：

$wp_customize->add_control( new WP_Customize_Control( $wp_customize, 'ounox-fonts-display-control', array(
    'label' => 'Fonts Section',
    'section' => 'ounox-fonts-section',
    'settings' => 'ounox-fonts-display',
    'type' => 'select',
    'choices' => $str
)));

循环不需要计数器，因此

$i

是冗余的。 您还将在每次迭代中覆盖

$str

$str = '';
foreach ($items as $font_value => $item) {
    $str .= $item['family']; // . '##' in case you need a delimiter
}

---

选项

参数，而不是字符串，因此您需要将每个

$item['family']

保存到数组中，然后将该数组添加到参数中

Hapstyx还正确地指出，迭代循环不需要

$i++

选项

所需的下拉选项数组应如下所示：

$choices = array(
    'option-value-1'    => 'Option Title 1',
    'option-value-2'    => 'Option Title 2',
    'option-value-3'    => 'Option Title 3'
);

//predefine a blank array which we will fill with your options
$choices = array();

//loop through your items and that the values to the $choices array
foreach ($items as $font_value => $item) {
    $choices[$item['slug']] = $item['family']; //I'm assuming your $item array contains some sort of slug to set as the value, otherwise, comment the above out, and uncomment the below:
    // $choices[$item['family']] = $item['family']
}

//set your arguments
$args = array(
    'label'     => 'Fonts Section',
    'section'   => 'ounox-fonts-section',
    'settings'  => 'ounox-fonts-display',
    'type'      => 'select',
    'choices'   => $choices
);

//add the control
$wp_customize->add_control( new WP_Customize_Control( $wp_customize, 'ounox-fonts-display-control', $args));

我们可以像这样构建这种类型的阵列：

$choices = array(
    'option-value-1'    => 'Option Title 1',
    'option-value-2'    => 'Option Title 2',
    'option-value-3'    => 'Option Title 3'
);

//predefine a blank array which we will fill with your options
$choices = array();

//loop through your items and that the values to the $choices array
foreach ($items as $font_value => $item) {
    $choices[$item['slug']] = $item['family']; //I'm assuming your $item array contains some sort of slug to set as the value, otherwise, comment the above out, and uncomment the below:
    // $choices[$item['family']] = $item['family']
}

//set your arguments
$args = array(
    'label'     => 'Fonts Section',
    'section'   => 'ounox-fonts-section',
    'settings'  => 'ounox-fonts-display',
    'type'      => 'select',
    'choices'   => $choices
);

//add the control
$wp_customize->add_control( new WP_Customize_Control( $wp_customize, 'ounox-fonts-display-control', $args));
