使用Oracle數據庫11g R2根據輸入值在PHP中顯示信息

我有一個簡單的表單（main.php），它將輸入作爲電話號碼。的客戶：使用Oracle數據庫11g R2根據輸入值在PHP中顯示信息

<!DOCTYPE HTML> 
    <html> 
     <div style=margin:0 auto align=center > 
     <form action = "options.php" method = "get" /> 
      <p> <h3>Enter Phone Number:</h3> <input type = "text" name = 
            "cust_phone" /> 
      <p> <input type = "submit" value = "Submit" /> 
     </form> 
     </div> 
    </html>

該no。在Oracle數據庫中檢查已輸入的數據，如果客戶存在，那麼會顯示關於該客戶的信息，否則將添加一個新客戶以及電話號碼。（options.php）

 <!DOCTYPE HTML> 
    <html> 
     <body> Details of:<?php echo htmlentities($_GET["cust_phone"])."<br>"; 

    $link = oci_connect('hd', 'hd', 'localhost/mydb'); 
    if(!$link) 
     {  
      $e = oci_error(); 
      exit('Connection Error' . $e['message']); 
     } 
    $query = "select cust_id from customer where cust_phone = :ph_bv"; 
    $stid = oci_parse($link,$query); 
    $ph = htmlentities($_GET["cust_phone"]); 
    oci_bind_by_name($stid, ':ph_bv', $ph); 
    oci_execute($stid); 
    $row = oci_fetch_array($stid, OCI_ASSOC); 
    if(!$row) 
    { 
     exit("Person Not Found"); 
    } 
    $cust_id = $row["ID"]; 
    oci_free_statement($stid); 
?> 
    <table border = "black" /> 
     <tr> 
      <th> ADDRESS </th> 
      <th> AREA </th> 
     </tr> 
    <?php 
     $query1 = "select a.address, a.area from customer c 
       join customer_address ca on c.cust_id = ca.cust_id 
       join address a on a.address_id = ca.address_id where cust_id = 
    :id_bv"; 
     $stid1 = oci_parse($link, $query1); 
     oci_bind_by_name($stid1, ":id_bv", $cust_id); 
      oci_execute($stid1); 
      while($row = oci_fetch_array($stid1)) 
      { 
       echo "<tr><td>" . htmlentities($row["ADRESS"]) . "</td>"; 
       echo "<td>" . htmlentities($row["AREA"]) . "</td></tr>"; 
      } 
      oci_free_statement($stid1); 
      oci_close($link); 
     ?> 
     </table> 
      </body> 
     </html>

代碼的第一部分工作正常，它顯示消息「人未找到」。然而，第二部分給出了錯誤：的詳情：9711210000

 (!) Notice: Undefined index: ID in 
      E:\xampp\htdocs\myfiles\options.php on line 24 
    Call Stack

我有兩個問題：1。相反，我想在我的數據庫添加新客戶「找不到人」的？ 2.如何解決這些錯誤？我是PHP新手，這只是我的第一個代碼。任何幫助讚賞。

$ row沒有記錄，所以你不能訪問$ row [「ID」]，所以首先檢查記錄是否存在，然後才能訪問數據。

第二個問題與您的查詢有關，cust_id字段在兩個表中，因此在編寫查詢時使用別名。

嘗試用下面的代碼： -

<!DOCTYPE HTML> 
    <html> 
     <body> Details of:<?php echo htmlentities($_GET["cust_phone"])."<br>"; 

    $link = oci_connect('hd', 'hd', 'localhost/mydb'); 
    if(!$link) 
     {  
      $e = oci_error(); 
      exit('Connection Error' . $e['message']); 
     } 
    $query = "select cust_id from customer where cust_phone = :ph_bv"; 
    $stid = oci_parse($link,$query); 
    $ph = htmlentities($_GET["cust_phone"]); 
    oci_bind_by_name($stid, ':ph_bv', $ph); 
    oci_execute($stid); 
    $row = oci_num_rows($stid); 
    $cust_id =''; 
    if($row>0) 
    { 
     $rows = oci_fetch_array($stid, OCI_ASSOC); 
     $cust_id = $rows["ID"]; 
     oci_free_statement($stid); 
     exit("Person Not Found"); 
    } 

?> 
    <table border = "black" /> 
     <tr> 
      <th> ADDRESS </th> 
      <th> AREA </th> 
     </tr> 
    <?php 
     $query1 = "select a.address, a.area from customer c 
       join customer_address ca on c.cust_id = ca.cust_id 
       join address a on a.address_id = ca.address_id where c.cust_id = 
    :id_bv"; 
     $stid1 = oci_parse($link, $query1); 
     oci_bind_by_name($stid1, ":id_bv", $cust_id); 
      oci_execute($stid1); 
      while($row = oci_fetch_array($stid1)) 
      { 
       echo "<tr><td>" . htmlentities($row["ADRESS"]) . "</td>"; 
       echo "<td>" . htmlentities($row["AREA"]) . "</td></tr>"; 
      } 
      oci_free_statement($stid1); 
      oci_close($link); 
     ?> 
     </table> 
      </body> 
     </html>

它給錯誤的結果爲現有phone_no。它不會爲任何現有電話號碼返回任何行。 'oci_num_rows'= 0即使是現有的pnoe no。告訴我如何將CUST_ID的值存儲在由第一個查詢檢索的變量中，即「從customer where cust_phone =：ph_bv」中選擇cust_id。 –

所有輸入的結果仍然相同。查詢在sql * plus中完美運行。我想問一個問題，什麼是$行[「ID」]。它存儲什麼價值？它是我數據庫中的列名，因爲我的數據庫中的列是'cust_id'。 –

是的ID應該是列名。我認爲這是專欄，所以沒有更新代碼 – gyaan

 <!DOCTYPE HTML>

     $e = oci_error(); 
     exit('Connection error ' . $e['message']); 
    } 
    $ph = htmlentities($_GET["cust_phone"]); 

    $q1 = "select CUST_ID from customer where CUST_PHONE = :bv_ph"; 
    $q1parse = oci_parse($link, $q1); 
    oci_bind_by_name($q1parse, ':bv_ph', $ph); 

    oci_execute($q1parse); 
    oci_fetch($q1parse); 
    $res = oci_result($q1parse, 'CUST_ID'); 
    if(!$res) { 
     exit("Person Not Found"); 
    } 
    ?> 
    <table border = "black"> 
     <tr>
