如何从PHP数组中填充Listbox /下拉框/选择框

Question

我需要编写自定义数组或JSON来填充Listbox /下拉框/选择框并添加属性selected="selected"。

例如：

<select id="test1" name="selectB" class="Field"> 
<option value="NO" selected="selected">No (Recommended)</option> 
<option value="YES">Yes</option> 
</select> 

我无法弄清楚如何做到这一点。

Answer 1

<?php 
$array = array(
    array("value"=>"NO","label"=>"No (Recommended)","selected"=>true), 
    array("value"=>"YES","label"=>"Yes","selected"=>false), 
); 


?> 

<select> 
    <?php foreach($array as $option) { ?> 
     <option value="<?php echo $option['value'] ?>" <?php if($option['selected']){ ?>selected="selected"<?php }?>> 
      <?php echo $option['label'] ?> 
     </option> 
    <?php }?> 
</select> 

JSON相当于数组的是：

[{"value":"1","label":"No (Recommended)","selected":true},{"value":"2","label":"Yes","selected":false}] 

这是json_enconde($array);
