php - 具有多个字值的选项标签

Question

我在使用 post 发送多个单词值时遇到问题。例如，如果我发送字符串“Jazz and Blues”，它只会发送“Jazz”。你知道问题出在哪里吗？？感谢您的帮助。

<select name="zaner" required>

    <option value=""></option>
    <?php
    $z = array("Elektro", "Drum and Bass", "Hardcore", "House", "Techno", "Trance", "Dubstep", "Folk", "Pop", "Jazz and Blues", "Reggae", "RnB", "Rap", "Metal", "Punk", "Clasic", "Alternative", "Indie", "Rock", "Country", "Disco", "Funky", "Experimental", "Soul and ghospe");
    foreach ($z as $zaner) {                        
        echo "<option value=" .$zaner. ">" .$zaner. "</option>";
    }
?>
</select>

Answer 1

作为注意事项提到，您忘记在选择标签中指定 multiple="multiple"，即

<select name="zaner[]" multiple="multiple" required>
    <option value=""></option>
<?php
$z = array("Elektro", "Drum and Bass", "Hardcore", "House", "Techno", "Trance", "Dubstep", "Folk", "Pop", "Jazz and Blues", "Reggae", "RnB", "Rap", "Metal", "Punk", "Clasic", "Alternative", "Indie", "Rock", "Country", "Disco", "Funky", "Experimental", "Soul and ghospe");
foreach ($z as $zaner) {                        
    echo "<option value=" .$zaner. ">" .$zaner. "</option>";
}
?>
</select>
