PHP：爲什麼我的代碼不能插入數據庫

Question

我正在開發一個高級項目，我一直在開發一個使用PHP從數據庫讀取/寫入數據的站點。我可以成功讀取數據到網站，但是在寫入數據時，我無法用網站上的表單數據填充我的Oracle數據庫。假設連接是正確的，因爲這與我用來讀取數據的連接是一樣的，並且它工作正常。

if($_POST['formSubmit'] == "Submit") 
{ 
    // Add validation code here 

    // Variable definition -- student info 
    $varOrg = $_POST['orgdept']; 
    $varFirst = $_POST['first']; 
    $varLast = $_POST['last']; 
    $varUID = $_POST['uid']; 
    $varStudentEmail = $_POST['semail']; 
    $varPhone = $_POST['sphone']; 
    $varOrgEmail = $_POST['orgemail']; 
    $varAdvisorName = $_POST['advisorname']; 


    // Variable definition -- event info 
    $varEventName = $_POST['eventname']; 
    $varEventDate = $_POST['eventDate']; 
    $varStartTime = $_POST['startTime']; 
    $varEndTime = $_POST['endTime']; 
    $varAttendance = $_POST['attendance']; 
    $varOpenTo = $_POST['opento']; 

    // ADD code for recurring dates 

    // Variable definition -- event logistics 
    $varEventType = $_POST['eventtype']; 
    $varOtherType = $_POST['othertypein']; 
    $varLocation = $_POST['locationselect']; 
    $varOtherIN = $_POST['inother1']; 
    $varPrefRoom1 = $_POST['proom1']; 
    $varPrefRoom2 = $_POST['proom2']; 
    $varOtherOUT = $_POST['outother1']; 
    $varDMNecess = $_POST['dmnecess']; 
    $varDMPowerON = $_POST['poweron']; 
    $varDMPowerOFF = $_POST['poweroff']; 
    $varDescription = $_POST['description']; 

    // Variable definition - add'l necessities 
    $varAmpSoundDesc = $_POST['ampsound']; 
    $varSecurityDesc = $_POST['security']; 
    $varFoodDesc = $_POST['food']; 
    $varChildrenDesc = $_POST['children']; 
    $varElectricityDesc = $_POST['electricity']; 
    $varSponsorshipDesc = $_POST['sponsorship']; 

    // Variable definition - signature/date 
    $varSignature = $_POST['signature']; 
    $varSignDate = $_POST['signdate']; 

    $db = oci_connect('ASSUME CORRECT'); 
    if (!$db) { 
     $e = oci_error(); 
     trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR); 
     die("Error connecting to the database."); 
    } 
    else 
    { 
     $sql = "INSERT INTO EVENT(EVENT_ID, STATUS, GROUP_NAME, STUDENTID, CONTACT_FIRST, CONTACT_LAST, EMAIL, PHONE, EVENT_NAME, EVENT_START, EVENT_END, ATTENDANCE, E_LOCATION, EVENT_TYPE, E_DESCRIPTION, EVENT_DATE) ' . 
     'VALUES (SEQ_ID.NEXTVAL, 'PENDING', :groupname, :studentid, :first, :last, :email, :phone, :eventname, to_date(:eventstart, 'HH24:MI'), to_date(:eventend, 'HH24:MI'), :attendance, :location, :eventtype, :description, to_date(:eventdate, 'YYYY-MM-DD')); "; 

     $compiled = oci_parse($db, $sql); 

     oci_bind_by_name($complied, ':groupname', $varOrg); 
     oci_bind_by_name($compiled, ':studentid', $varUID); 
     oci_bind_by_name($compiled, ':first', $varFirst); 
     oci_bind_by_name($compiled, ':last', $varLast); 
     oci_bind_by_name($compiled, ':email', $varStudentEmail); 
     oci_bind_by_name($compiled, ':phone', $varPhone); 
     oci_bind_by_name($compiled, ':eventname', $varEventName); 
     oci_bind_by_name($compiled, ':eventstart', $varStartTime); 
     oci_bind_by_name($compiled, ':eventend', $varEndTime); 
     oci_bind_by_name($compiled, ':attendance', $varAttendance); 
     oci_bind_by_name($compiled, ':location', $varLocation); 
     oci_bind_by_name($compiled, ':eventtype', $varEventType); 
     oci_bind_by_name($compiled, ':description', $varDescription); 
     oci_bind_by_name($compiled, ':eventdate', $varEventDate); 

     oci_execute($compiled); 
    } 
} 
?> 

我已經給所有控件添加了名稱屬性，但它並沒有給我任何東西發佈到數據庫。誰能提供指導？

Answer 1

你在其中一個變量中存在拼寫錯誤。

oci_bind_by_name($complied, ':groupname', $varOrg); 
       ^^^^^^^^^ 

，它應該讀作$compiled

oci_bind_by_name($compiled, ':groupname', $varOrg); 

Answer 2

檢查SQL查詢正確

$sql = "INSERT INTO EVENT(EVENT_ID, STATUS, GROUP_NAME, STUDENTID, CONTACT_FIRST, CONTACT_LAST, EMAIL, PHONE, EVENT_NAME, EVENT_START, EVENT_END, ATTENDANCE, E_LOCATION, EVENT_TYPE, E_DESCRIPTION, EVENT_DATE) 
     VALUES (SEQ_ID.NEXTVAL, 'PENDING', :groupname, :studentid, :first, :last, :email, :phone, :eventname, to_date(:eventstart, 'HH24:MI'), to_date(:eventend, 'HH24:MI'), :attendance, :location, :eventtype, :description, to_date(:eventdate, 'YYYY-MM-DD')); "; 

Answer 3

退房這行代碼的：

$sql = "INSERT INTO EVENT(EVENT_ID, STATUS, GROUP_NAME, STUDENTID, CONTACT_FIRST, CONTACT_LAST, EMAIL, PHONE, EVENT_NAME, EVENT_START, EVENT_END, ATTENDANCE, E_LOCATION, EVENT_TYPE, E_DESCRIPTION, EVENT_DATE) ' . 
    'VALUES (SEQ_ID.NEXTVAL, 'PENDING', :groupname, :studentid, :first, :last, :email, :phone, :eventname, to_date(:eventstart, 'HH24:MI'), to_date(:eventend, 'HH24:MI'), :attendance, :location, :eventtype, :description, to_date(:eventdate, 'YYYY-MM-DD')); "; 

您打開$sql帶有雙引號的字符串，並用單引號將其關閉。在連接線上，用單引號將其打開，並用雙引號將其關閉。

與此，而不是替換它：

$sql = "INSERT INTO EVENT(EVENT_ID, STATUS, GROUP_NAME, STUDENTID, CONTACT_FIRST, CONTACT_LAST, EMAIL, PHONE, EVENT_NAME, EVENT_START, EVENT_END, ATTENDANCE, E_LOCATION, EVENT_TYPE, E_DESCRIPTION, EVENT_DATE) " . 
    "VALUES (SEQ_ID.NEXTVAL, 'PENDING', :groupname, :studentid, :first, :last, :email, :phone, :eventname, to_date(:eventstart, 'HH24:MI'), to_date(:eventend, 'HH24:MI'), :attendance, :location, :eventtype, :description, to_date(:eventdate, 'YYYY-MM-DD')); "; 

退房這一行，太：

oci_bind_by_name($complied, ':groupname', $varOrg); 

你拼錯compiled爲complied。

這種替換：

oci_bind_by_name($compiled, ':groupname', $varOrg);
