数组值的替换

Question

新手来了。我正在尝试创建一个WordPress插件，并获得以下代码来显示字体选择的下拉列表。它可以工作，但看起来是错误的，效率也不高，有什么方法可以在不编写if语句的情况下更改数组的显示值？

$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'; }
}
}

我只做了一个关联数组：

$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";
}

尽管大多数字体名称都是小写的，并且没有标点符号，但是您也可以创建一个泛型函数，然后只考虑特殊情况。

无论哪种方式，这段代码都太复杂了。为什么需要这样做？

您可以尝试如下所示：

$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
        }
    }
}
