驗證動態填充在PHP

-1

文本框中領域，您好我試圖在較早的筆記中找到答案我的以下問題也不過便無法。可以有一個人請不要突出我在哪裏出了錯？驗證動態填充在PHP

我的問題是，當點擊Save按鈕，不論文本框是否有一個值或空，它總是打印保存的信息！只是它不驗證文本框的值。

還要注意的文本框通過循環填充。

謝謝。

一個建議，HTML，PHP搭配是非常混亂的，它的更好，如果代碼被分離PHP和HTML，所以它更容易理解和調試的。 –

重複[動態文本框的值不會捕獲驗證 - PHP]（http://stackoverflow.com/questions/17280029/dynamic-text-box-value-doesnt-capture-in-validation-php） – CBroe

@ CBroe是否在這裏閱讀我的問題？ –

if(!isset($_POST['allocas']) || $_POST['allocas'] == '')

很可能是你的問題行。如果allocas未設置或設置爲空，這將返回true。

你的意思也許是啥子：

if(!(isset($_POST['allocas']) || $_POST['allocas'] == ''))

這將返回true只有allocas包含文本。
