Question

新手在这里。我正在尝试创建一个WordPress插件，我得到以下代码来显示字体选择的下拉列表。它工作但看起来错误而且效率不高，在不编写if语句的情况下更改数组显示值的方法是什么？

$plugin_options = get_option('plugin_options');
$plugin_fonts_array = array('Chunk', 'Crimson', 'Deja Vu Sans', 'Deja Vu Sans Condensed', 'Deja Vu Mono', 'Deja Vu Serif', 'Deja Vu Serif Condensed', 'IM Fell French Canon', 'Junction', 'Lato Light', 'Lato Regular', 'Lato Black', 'League Gothic Condensed', 'League Gothic Regular', 'League Script Number One', 'Linux Libertine', 'Linux Libertine Display', 'Linux Libertine Mono', 'OCRB', 'Open Baskerville', 'Open Sans Light', 'Open Sans', 'Open Sans Semi Bold', 'Open Sans Extra Bold', 'Prociono', 'Raleway Thin', 'Source Sans Pro Extra Light', 'Source Sans Pro Light', 'Source Sans Pro', 'Source Sans Pro Semi Bold', 'Source Sans Pro Black');
foreach ($plugin_fonts_array as $font) {
    if ($font == $plugin_options['dropdown1']) {
        $plugin_front_font = $plugin_options['dropdown1'];      
    if ($plugin_front_font == 'Chunk') { $plugin_front_font = 'chunk'; }
    if ($plugin_front_font == 'Crimson') { $plugin_front_font = 'crimson'; }
    if ($plugin_front_font == 'Deja Vu Sans') { $plugin_front_font = 'DejaVuSans'; }
    if ($plugin_front_font == 'Deja Vu Sans Condensed') { $plugin_front_font = 'DejaVuSansCondensed'; }
    if ($plugin_front_font == 'Deja Vu Mono') { $plugin_front_font = 'DejaVuSansMono'; }
    if ($plugin_front_font == 'Deja Vu Serif') { $plugin_front_font = 'DejaVuSerif'; }
    if ($plugin_front_font == 'Deja Vu Serif Condensed') { $plugin_front_font = 'DejaVuSerifCondensed'; }
    if ($plugin_front_font == 'IM Fell French Canon') { $plugin_front_font = 'imfellfrenchcanon'; }
    if ($plugin_front_font == 'Junction') { $plugin_front_font = 'junction'; }
    if ($plugin_front_font == 'Lato Light') { $plugin_front_font = 'latolight'; }
    if ($plugin_front_font == 'Lato Regular') { $plugin_front_font = 'latoregular'; }
    if ($plugin_front_font == 'Lato Black') { $plugin_front_font = 'latoblack'; }
    if ($plugin_front_font == 'League Gothic Condensed') { $plugin_front_font = 'leaguegothiccondensedregular'; }
    if ($plugin_front_font == 'League Gothic Regular') { $plugin_front_font = 'leaguegothicregular'; }
    if ($plugin_front_font == 'League Script Number One') { $plugin_front_font = 'leaguescriptnumberone'; }
    if ($plugin_front_font == 'Linux Libertine') { $plugin_front_font = 'linuxlibertine'; }
    if ($plugin_front_font == 'Linux Libertine Display') { $plugin_front_font = 'linuxlibertinedisplay'; }
    if ($plugin_front_font == 'Linux Libertine Mono') { $plugin_front_font = 'linuxlibertinemono'; }
    if ($plugin_front_font == 'OCRB') { $plugin_front_font = 'ocrb10'; }
    if ($plugin_front_font == 'Open Baskerville') { $plugin_front_font = 'openbaskerville'; }
    if ($plugin_front_font == 'Open Sans Light') { $plugin_front_font = 'opensanslight'; }
    if ($plugin_front_font == 'Open Sans') { $plugin_front_font = 'opensans'; }
    if ($plugin_front_font == 'Open Sans Semi Bold') { $plugin_front_font = 'opensanssemibold'; }
    if ($plugin_front_font == 'Open Sans Extra Bold') { $plugin_front_font = 'opensansextrabold'; }
    if ($plugin_front_font == 'Prociono') { $plugin_front_font = 'prociono'; }
    if ($plugin_front_font == 'Raleway Thin') { $plugin_front_font = 'ralewaythin'; }
    if ($plugin_front_font == 'Source Sans Pro Extra Light') { $plugin_front_font = 'sourcesansproextralight'; }
    if ($plugin_front_font == 'Source Sans Pro Light') { $plugin_front_font = 'sourcesansprolight'; }
    if ($plugin_front_font == 'Source Sans Pro') { $plugin_front_font = 'sourcesanspro'; }
    if ($plugin_front_font == 'Source Sans Pro Semi Bold') { $plugin_front_font = 'sourcesansprosemibold'; }
    if ($plugin_front_font == 'Source Sans Pro Black') { $plugin_front_font = 'sourcesansproblack'; }
}
}

我只是制作一个关联数组：

$plugin_options = get_option('plugin_options');

$font_map = array(
    'Chunk' => 'chunk',
    'Crimson' => 'crimson',
    'Deja Vu Sans' => 'DejaVuSans',
    'Deja Vu Sans Condensed' => 'DejaVuSansCondensed',
    'Deja Vu Mono' => 'DejaVuSansMono',
    'Deja Vu Serif' => 'DejaVuSerif',
    'Deja Vu Serif Condensed' => 'DejaVuSerifCondensed',
    'IM Fell French Canon' => 'imfellfrenchcanon',
    'Junction' => 'junction',
    'Lato Light' => 'latolight',
    'Lato Regular' => 'latoregular',
    'Lato Black' => 'latoblack',
    'League Gothic Condensed' => 'leaguegothiccondensedregular',
    'League Gothic Regular' => 'leaguegothicregular',
    'League Script Number One' => 'leaguescriptnumberone',
    'Linux Libertine' => 'linuxlibertine',
    'Linux Libertine Display' => 'linuxlibertinedisplay',
    'Linux Libertine Mono' => 'linuxlibertinemono',
    'OCRB' => 'ocrb10',
    'Open Baskerville' => 'openbaskerville',
    'Open Sans Light' => 'opensanslight',
    'Open Sans' => 'opensans',
    'Open Sans Semi Bold' => 'opensanssemibold',
    'Open Sans Extra Bold' => 'opensansextrabold',
    'Prociono' => 'prociono',
    'Raleway Thin' => 'ralewaythin',
    'Source Sans Pro Extra Light' => 'sourcesansproextralight',
    'Source Sans Pro Light' => 'sourcesansprolight',
    'Source Sans Pro' => 'sourcesanspro',
    'Source Sans Pro Semi Bold' => 'sourcesansprosemibold',
    'Source Sans Pro Black' => 'sourcesansproblack'
);

$dropdown_font = $plugin_options['dropdown1'];

if (array_key_exists($dropdown_font, $font_map)) {
    $plugin_front_font = $font_map[$dropdown_font];
} else {
    echo "Invalid font";
}

虽然由于大多数字体名称只是小写且没有标点符号，您也可以创建一个通用函数，然后只考虑特殊情况。

无论哪种方式，这段代码都太复杂了。你为什么需要这样做？

您可以尝试这样的事情：

$plugin_options = get_option('plugin_options');
$plugin_fonts_array = array('Chunk', 'Crimson', 'Deja Vu Sans', 'Deja Vu Sans Condensed', 'Deja Vu Mono', 'Deja Vu Serif', 'Deja Vu Serif Condensed', 'IM Fell French Canon', 'Junction', 'Lato Light', 'Lato Regular', 'Lato Black', 'League Gothic Condensed', 'League Gothic Regular', 'League Script Number One', 'Linux Libertine', 'Linux Libertine Display', 'Linux Libertine Mono', 'OCRB', 'Open Baskerville', 'Open Sans Light', 'Open Sans', 'Open Sans Semi Bold', 'Open Sans Extra Bold', 'Prociono', 'Raleway Thin', 'Source Sans Pro Extra Light', 'Source Sans Pro Light', 'Source Sans Pro', 'Source Sans Pro Semi Bold', 'Source Sans Pro Black');
$plugin_fonts_flipped_array = array_flip($plugin_fonts_array);
foreach ($plugin_fonts_array as $font) {
    if ($font == $plugin_options['dropdown1']) {
    $plugin_front_font = $plugin_options['dropdown1'];
        if(isset($plugin_fonts_flipped_array[$plugin_front_font])){
            $plugin_front_font = strtolower(str_replace(' ', '', $plugin_front_font)); // remove the whitespace and convert to lower space
        }
    }
}

替换数组值
