將PHP合併到HTML表格中

我想知道是否有人能夠幫助我。將PHP合併到HTML表格中

我試圖把功能，它允許管理員使用電子郵件地址作爲搜索條件在mySQL數據庫中搜索用戶的詳細信息。一旦搜索結果發生，我希望我的表單中的「第一」和「姓氏」字段在檢索到的記錄中完成。

我認爲搜索工作的形式刷新，但它不檢索任何可見的信息。

我只是想知道是否有人可能會看看我的代碼，並讓我知道我哪裏出了問題。

非常感謝

您應經常檢查或將其連接到查詢之前santize你輸入什麼？如果有人要輸入''; DROP TABLE userdetails; - 作爲電子郵件？ –

@KileyNaro如果你正在嘗試註冊某些東西，我會說這相當適得其反：V – sg3s

嚴肅的一面，你沒有告訴我們這個代碼出了什麼問題。你也可以用'$ email = mysql_real_escape_string（$ _ POST ['email']，$ connection）';'來代替當前的'$ email'聲明來清理你的電子郵件。 – sg3s

-2

只是在看你的代碼breifly，我不認爲你的電子郵件的價值正確地傳遞到您的SQL查詢。

嘗試使用此。

$result = mysql_query("SELECT * FROM userdetails WHERE emailaddress like '%" . $email . "%'");

PHP允許你在字符串中間使用變量，所以我不認爲這是問題。 –

嗯，不知道，你的代碼是用PHP做的，我來自C＃背景，所以對我來說看起來像是一個重大的錯誤。我應該保留我的答案還是刪除它？ – alykhalid

嗨，我敢肯定，問題不在於電子郵件的價值不被傳遞，因爲我已經嘗試了這個作爲一個單獨的代碼片，它工作正常。我發現一個掙扎是將表單和php結合在一起。非常感謝。 – IRHM

你不缺少的步驟，其中在實際運行鍼對您的查詢mysql_fetch_assoc功能？只需將mysql_query的結果分配給變量$result是不夠的！

您的來電後，加入這樣的事情mysql_query：

if($result) 
{ 
    $row = mysql_fetch_assoc($result)); 
}

編輯：mysql_fetch_assoc PHP documentation

要獲得所有的行導致與查詢你需要使用MySQL取功能（有是幾個）。

的優先停留方法是definitly mysql_fetch_assoc

你的代碼的相關部分將是這個樣子：

$email = mysql_real_escape_string($_POST['email']); // make the value safe for in the query 
$result = mysql_query("SELECT * FROM userdetails WHERE emailaddress like '%$email%'"); 
$rows = array(); 

while ($row = mysql_fetch_assoc($result)) { 
    $rows[] = $row; 
} 

// $rows is now a multi dimensional array with values found by the query

嗨，非常感謝您花時間幫助我解決這個問題。我對此很新，所以請原諒我對此採取的緩慢行動。我修改了我的代碼以包含您的文本。表單呈現，我鍵入搜索條件，但唯一發生的是頁面刷新。我已將更新的代碼添加到我的原始帖子中。你能告訴我哪裏出錯了嗎？問候 – IRHM

將結果放入數組後，您仍然必須使用'$ rows'做些事情。嘗試'print_r（$ rows，true）;'查看從數據庫獲得的結果。如果它沒有產生任何結果，那可能是因爲沒有任何結果。要重新檢查一下，只需嘗試在phpmyadmin中用您的輸入電子郵件地址執行該查詢並查看會發生什麼。基本的PHP調試真的。閱讀一些教程:) – sg3s
