Question

$states = array( 
        "NSW" => "NSW",
        "VIC" => "VIC",
        "QLD" => "QLD",
        "SA" => "SA",
        "WA" => "WA",
        "TAS" => "TAS",
        "NT" => "NT",
        "ACT" => "ACT",
        "OTH" => "OTH (AUS)",
        "OVS" => "OVS (Overseas)"
        );

现在我希望值为select和变量的值。

foreach ($states as $key  => $value) {
    $form_ret .= "<option value='".$key."'>".$key[1]."</option>";
}

但我无法从OVS (Overseas)获得OVS的确切值。

我真正想要的是这样的：

<select name="State" id="State" >
<option value="NSW">NSW </option>
<option value="VIC">VIC </option>
<option value="QLD">QLD </option>
<option value="SA">SA </option>
<option value="WA">WA </option>
<option value="TAS">TAS </option>
<option value="NT">NT </option>
<option value="ACT">ACT </option>
<option value="OTH">OTH (AUS)</option>
<option value="OVS">OVS (Overseas)</option>
</select>

有没有人对我的案子有所了解？提前谢谢

Answer 1

将$key[1]替换为$value：

foreach ($states as $key => $value) {
    $form_ret .= "<option value='".$key."'>".$value."</option>";
}

Answer 2

我认为您打算使用$value代替$key[1]

foreach ($states as $key  => $value) {
    $form_ret .= "<option value='".$key."'>".$value."</option>";
}

Answer 3

键[1]的值不正确。它表示键的1个字符串

必须使用$ value来显示正确的

Answer 4

echo '<select name="State" id="State">';
foreach ($states as $key => $value){
echo '<option value="'.$key.'">'.$value.'</option>';
}echo '</select>';

这是你应该获得的HTML

    <select id="State" name="State">
    <option value="NSW">NSW</option>
    <option value="VIC">VIC</option>
    <option value="QLD">QLD</option>
    <option value="SA">SA</option>
    <option value="WA">WA</option>
    <option value="TAS">TAS</option>
    <option value="NT">NT</option>
    <option value="ACT">ACT</option>
    <option value="OTH">OTH (AUS)</option>
    <option value="OVS">OVS (Overseas)</option>
    </select>
