我已经将 apple 的值从下拉选择中保存到 mysql 中。 现在在编辑页面中，我想显示相应的值。 但我似乎没弄对
<?php $food = $mysqli->real_escape_string($_POST['food']); ?>
<select id="food" required name="food" >
<option value="" disabled selected>Select a Food</option>
<option value="apple" <?php if($food == apple)
echo "selected='selected'"; ?>Apple</option>
<option value="kiwi" <?php if($food == kiwi)
echo "selected='selected'"; ?>Kiwi</option>
</select></div>最佳答案
<select id="food" required name="food" >
<option value="" >Select a Food</option>
<option value="apple" <?php if($food == "apple")
echo "selected='selected'"; ?>Apple</option>
<option value="kiwi" <?php if($food == "kiwi")
echo "selected='selected'"; ?>Kiwi</option>
</select></div>关于javascript - 显示从数据库(即 mysql)中选择的下拉值，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45005020/
