php下拉选择错误

Question

我有以下代码，它将必要的数据完美地插入到数据库中。但问题是，当我想实现 select="select".. 这样如果客户返回，他将看到他从下拉菜单中选择的内容......我该怎么做，任何想法......

<pre>
<?php
//array generated from mysql to feed first dropdown menu.
$newOptions = array();
    foreach ($input as $option) {
        $wclID = $option['desc'];
        $nameF = $option['fame'];
        $nameL = $option['lname'];
        $id = $option['ID'];
        $newOptions[$wclID][$id] = $nameL." ".$nameF;
    }

//second array for second dropdown menu
$array = array('ent','res');    
?>


   <div class="control-group">
        <div class="controls">
            <form  id="checkEnt" name="che" method="post" action="com.php?ID=<?=$ID?>">
                <input type="hidden" value="che" name="ent">
                <table class="table table-striped span10">
                    <tbody>
                        <? foreach ($newOptions as $wclID => $list) {  ?>
                            <tr><td width="5%">
                                    <h5><?=$wclID?> AA</h5>
                                </td>
                                <td width="10%">
                                    <label class="control-label" for="inputWei"><?=_('Boy')?></label>  
                                    <select class="input-xlarge" id="input" name="drop[0][]">

                                            <?php    } ?>
                                    </select>

Answer 1

我最近做了类似的事情。这是针对从数据库返回的数据正确的吗？如果是这样，那么我会实现类似的东西。

在选项标签上，我会尝试使用 if 语句来查看数据库中的内容，然后是否调用 selected=selected

<option value="Something" <? if(in_array('Something',$nameofArray)) echo 'selected="selected"';?>>Something</option>

或者在你的情况下你可能想尝试

<?foreach ($list as $key => $value) {?>
    <option value="$value" <? if($value) echo 'selected="selected"';?>>$value</option>

 <?}?>

Answer 2

使用选项标签的“selected”属性：
