我在 wordpress 中創建的插件中有一個表單。該表單是一個簡單的測驗表單，它有一個隱藏欄位和兩個文本欄位。如果我在文本欄位中輸入一個數字，當我點擊提交時它不會處理它，它會給我一個頁面，上面寫著
看起來在這個位置沒有發現任何東西。也許嘗試搜索？
這是顯示表單和處理表單的操作的整個插件。

我可以讓欄位 1 或欄位 2 獲取數字的唯一方法是將它們更改為 type="number"
有我可以使用的 varchar 型別嗎？
我的資料庫將欄位設定為 varchar。
提前致謝 Dean-O
uj5u.com熱心網友回復：
您應該為您的表單設定操作。
例如：'test.php' 或 '/'。
它對我來說效果很好。
我在這里重寫你的代碼：
<form role="form" method="post" action="{your menu slug}">
<div class="form-group">
<?php
// get current user ID, with default value, if empty
$current_user_id = get_current_user_id();
?>
<input type="hidden" name="wp_id" value="<?php echo esc_attr( $current_user_id ); ?>" />
</div>
<div class="form-group">
<label>Field 1</label><br>
<input id="title" name="title" type="text" placeholder="<?php echo esc_attr( $current_user_id ); ?>" required="">
</div>
<div class="form-group">
<label>Field 2</label><br>
<input id="author" name="author" type="text" placeholder="Primary Author" required="">
</div>
<div class="row justify-content-center">
<div class="col-xs-4 col-sm-4 col-md-4">
<br><input type="submit" value="Submit1" class="btn btn-info btn-block" name="submitbtn">
</div>
</div>
</form>uj5u.com熱心網友回復：
第一的：
您必須輸入標簽的action屬性form。
如果問題沒有解決：
您可能會收到錯誤訊息，因為它們的名稱是title和author！因此，將它們更改為其他名稱并查看結果
