Question

您好我需要一些帮助才能从数据库创建表单：Database

我有这个：

global $wpdb;
//$query ="SELECT modelo,ID FROM volumes"; 
$query ="SELECT Modelo,ID FROM volumes order by ID";
$wpdb->query($query)

而且：

<div class="form_fields">
<p>
<label for="modelo">Model:
echo "<select name=Modelo value=''>Modelo</option>"; // list box select command

foreach ($wpdb->query($query) as $row){//Array or records stored in $row

echo "<option value=$row[ID]>$row[Modelo]</option>"; 

/* Option values are added by looping through the array */ 

}

 echo "</select>";// Closing of list box
        </label>
    </p></div>

有什么问题？

global $wpdb;
//$query ="SELECT modelo,ID FROM volumes"; 
$query = "SELECT Modelo,ID FROM volumes order by ID";
$results = $wpdb->get_results($query);

<div class="form_fields">
    <p>
        <label for="modelo">Model:
            <select name=Modelo>
                <option value=''>Modelo</option>
                <?php
                foreach ($results as $row) {//Array or records stored in $row
                    echo "<option value='{$row->ID}'>{$row->Modelo}</option>";
                    /* Option values are added by looping through the array */
                }
                ?>
            </select>
        </label>
