使用 php 縮寫下拉菜單中的狀態

[英]Using php for abbreviating the states in a drop down menu

問題描述

我又回來了，我知道你們可能厭倦了我，哈哈，但我想出了一些如何添加文本框的方法。 我仍然無法使用下拉菜單。 我應該有一個下拉菜單，其中包含州列表，當您提交時，它會被縮寫，但這也不適合我。 我很確定它很容易修復，我一直在尋找它。

嘗試這個：

    $db=mysqli_connect(null,null,null,'weblab')
    or die("Can't connect to DB:" . mysqli_connect_error());
    $q = " select fruit_item_no, fruit_name, fruit_weight, fruit_price";
    $q .= " from fruit_t";
    $q .= " order by fruit_name;";
    $dbResult = mysqli_query($db,$q);
    $num = mysqli_num_rows($dbResult);
    if ($num == 0) {
     echo '<tr><td colspan="2">';
    echo 'Database query retrieved zero rows.</td></tr>';
    }
while ($row = mysqli_fetch_assoc($dbResult)) {
$name = $row['fruit_name'];
$weight = $row['fruit_weight'];
$price = $row['fruit_price'];
echo "<tr><td><b>$name</b></td>";
echo "<td>$weight</td>";
echo "<td>$price</td>";
echo "<td><input type='text' name='name'></td></tr>\n";
?>
</table>
<label>State:
    <select name="state" id="state">
     <?php
    $db=mysqli_connect(null,null,null,'weblab')
     or die("Can't connect to DB:" . mysqli_connect_error());
    $q = " select state_abbr, state_name";
    $q .= " from state_t";
    $q .= " order by state_name;";
    $dbResult = mysqli_query($db,$q);
    while ($x = mysqli_fetch_assoc($dbResult)) {
    $state_abbr = $x["state_abbr"];
    $state_name = $x["state_name"];
?>
<option value="<?php echo $state_id; ?>">
    <?php echo $state_name; ?></option>
<?php
}
?>
        </select>
</label>

這就是代碼縮進如此重要的原因。您在兩個地方遺漏了關閉 PHP 標記。 參考下面的代碼。
