未定義指數：operator_id

-3

我使用此代碼使用PHP和數據接入，但在Oracle數據庫中，我使用NOT NULL值。但是當我刷新頁面，然後得到錯誤數據插入到Oracle數據庫：未定義指數：operator_id

未定義指數：在

代碼

<?php 
{ 
    $ora_conn = oci_connect('system','oracle','//localhost/XE'); 
    if(!$ora_conn) 
    { 
     $m = oci_error(); 
     echo $m['message'], "\n"; 
     exit; 
    } 
    else 
    {

    { 
     $optid = $_POST['operator_id']; 
     $optdec = $_POST['operater_description']; 
     $empid = $_POST['employee_id']; 
     $empmail = $_POST['employee_emailid'];

這被問道相當頻繁。它與Oracle無關。看看[PHP的：「注意：未定義的變量」和「注意：未定義的索引」]（http://stackoverflow.com/questions/4261133/php-notice-undefined-variable-and-notice-undefined-index） –

使用operator_id下面的代碼：

$optid = isset($_POST['operator_id']) ? $_POST['operator_id'] : ''; 
$optdec = isset($_POST['operater_description']) ? $_POST['operater_description'] : ''; 
$empid = isset($_POST['employee_id']) ? $_POST['employee_id'] :''; 
$empmail = isset($_POST['employee_emailid']) ? $_POST['employee_emailid'] : '';

可能是您沒有從表單中發佈operator_id的數據。

謝謝，但我有這條線上的錯誤注意：未定義的索引：operator_id在 $查詢=「選擇*從optr_add在哪裏OPERATOR_ID ='」。$ _ POST ['operator_id']。「' – user2842666

您確定在此頁面上通過POST收到「operator_id」字段嗎？

這個問題似乎是

$_POST['operator_id']

控制用的var_dump（）或將您的變量在isset

if(isset($_POST['operator_id']){ 
//do something 
}

plz解釋我是新的php編碼 – user2842666

你故意刷新頁面，您接收到的數據？刷新頁面時會是什麼？如果刷新頁面時不需要執行任何操作，則應修改if語句。現在，如果提交了郵件，你會進入如果...當你沒有帖子時，你去其他部分...你有一個錯誤，因爲你沒有在你的手中發佈數據，你正試圖做一些事情後數據。

使用更新的代碼，並作出嘗試：

<?php 
$ora_conn = oci_connect('system','oracle','//localhost/XE'); 
if(!$ora_conn) 
{ 
    $m = oci_error(); 
    echo $m['message'], "\n"; 
    exit; 
} 
else 
{ 
    //print "You are connected to the database!<br/>"; 
} 
if (isset($_POST['Submit'])) 
{ 
    $optid = $_POST['operator_id']; 
    $optdec = $_POST['operater_description']; 
    $empid = $_POST['employee_id']; 
    $empmail = $_POST['employee_emailid']; 
    $query = "SELECT * FROM optr_add WHERE OPERATOR_ID= 
     '".$_POST['operator_id']."' OR   
     employee_emailid = '".$_POST['employee_emailid']."' 
     OR employee_id =  '".$_POST['employee_id']."'"; 
    $s=oci_parse($ora_conn, $query); 
    oci_execute ($s,OCI_DEFAULT); 
    $objResult = oci_fetch_array($s); 
    if($objResult) 
    { 
     echo "<script>alert('Operator ID already exist')</script>"; 
    } 
    else 
    { 
     $query = 'INSERT INTO optr_add 
      (operator_id , operater_description ,employee_id,employee_emailid)**<<---here**  
      VALUES (:operator_id ,:operater_description,:employee_id,:employee_emailid)'; 

     $s=oci_parse($ora_conn, $query); 
     oci_bind_by_name($s, ':operator_id', $optid); 
     oci_bind_by_name($s, ':operater_description', $optdec); 
     oci_bind_by_name($s, ':employee_id', $empid); 
     oci_bind_by_name($s, 'employee_emailid', $empmail); 
     if (isset($_POST['Submit'])) 
      $objExecute=oci_execute($s); 
     if (isset($_POST['Submit'])) 
     { 
      if (!isset($optid) || empty($optid)) 
      { 
       //header("refresh:1110;url=Define_Organization.php"); 
       echo"<script>alert('Submit Successfully')</script>"; 
       exit(); 
       echo"<script>alert('Please enter your data')</script>"; 
       exit(); 
      } 
     } 
     oci_free_statement($s); 
     oci_close($ora_conn); 
    }  
}

當我提交帶有空值的添加按鈕時，我得到新的錯誤 oci_execute（）：ORA-01400：不能將NULL插入（「SYSTEM」。「OPTR_ADD」。「OPERATOR_ID」） – user2842666

但這個編碼部分不是工作回聲「」; 出口（）; – user2842666

看來你錯過一些輸入。好之前執行oci_execute（）嘗試的print_r（$ _ POST）或單獨回聲$ _ POST [「經營者」]等。然後嘗試執行oci_execute（） – Nes
