好的,所以我有一個我正在嘗試創建的網站的表單。我試圖將來自HTML的用戶輸入存儲到字符串值中以顯示在PHP中。麻煩的是,當我輸入數字值時,我無法識別PHP。這適用於「單選按鈕」類型輸入,但不適用於純文本。我已經包含了該網站的兩個頁面的代碼。 塔設計中心 - 在這裏建立自己的塔! 沒有註冊爲數組中的字符串的數字

我有什麼至今在PHP代碼:

<?php var_dump($_POST) ?><br> 
    Pillar base shape: <?php echo $_POST["tBase"]; ?><br> 
    Pillar dimensions: <?php echo htmlspecialchars($_POST["tHeight"])." x ".htmlspecialchars($_POST["tWidth"])." x ".htmlspecialchars($_POST["tDepth"]); ?><br> 

到目前爲止,當這些結果進行組合,我可以看到的var_dump陣列中的字符數形狀(即[「tBase」] =>字符串(7)「八角形」),但是對於數字值來說,沒有字符計數,這意味着數值沒有通過。任何人都可以幫我解決這個問題嗎?謝謝。

良好的通話。我檢查了我的代碼,結果證明我有重複。 ...但即使是變化的變化,它仍然顯示爲0 x 0 x 0. –

好的,我不需要你爲我完成整個代碼,但是我從代碼中獲取了所需的代碼。謝謝。我可以自己完成所有其他事情,例如使用我所做的一切。 –

See inval()

說明

int intval (mixed $var [, int $base = 10 ]) 

返回var整數值,使用用於轉換指定基本(默認爲10爲底)。 intval()不應該用在對象上,因爲這樣做會發出E_NOTICE級錯誤並返回1

所以,如果你輸入$_POST["value"],你可以用整數值:

$integer_value = intval($_POST["value"]);

我將這行代碼複製/粘貼到我現有的代碼中。當我將它放入時,它會拋出以下消息:注意:未定義的索引:第9行中的C:\ XAMPP \ htdocs \ tower \ testfile_post.php中的值。和之前一樣。我應該在哪裏放這個代碼? –

$ _POST [「value」]是一個佔位符。用你試圖使用的實際值對應的鍵名(從表單中)替換「value」 –

好的,我試了一下。現在它在結果屏幕上註冊爲「0 x 0 x 0」,不管我輸入什麼號碼。任何人都知道這可能是爲什麼? –
