自動完成PHP JQuery Oracle

我試圖讓Autocomplete與Oracle數據庫一起工作。自動完成PHP JQuery Oracle

我發現了測試代碼，並試圖讓它與Oracle一起工作，但它不起作用，我不知道問題是在未觸及的搜索表單中還是在backend-search.php（原始代碼是仍然在代碼評論＃）

如果我在文本框中鍵入沒有任何反應。

數據庫連接在另一個表單上進行測試，我將數據獲取到表中。

如果有人能給我一個提示，我將不勝感激。

搜索form.php的

<!DOCTYPE html> 
<html lang="de"> 
<head> 
<meta charset="UTF-8">

<style type="text/css">

後端-search.php中

    $pass = 'xxxxx'; 
    $conn = oci_connect($dbuser, $pass, $db); 

if(isset($_REQUEST['term'])){ 
    // Prepare a select statement 
    #$sql = 'SELECT Standortname FROM DATABASE WHERE Standortname LIKE :s'; 
    #if($stmt = mysqli_prepare($conn, $sql)){ 
    if($stmt = oci_parse($conn, "SELECT Standortname FROM Database WHERE Standortname LIKE :s")){ 
     // Bind variables to the prepared statement as parameters 
     #mysqli_stmt_bind_param($stmt, "s", $param_term); 
     oci_bind_by_name($stmt , ':s' , $param_term, -1); #$ph_name

     #if(mysqli_stmt_execute($stmt)){ 
     if(oci_execute($stmt)){

      $result = oci_result($stmt); 
      // Check number of rows in the result set

      }

if(isset($_REQUEST['term']) and (strlen($_REQUEST['term']) >= 3)){ 
    if($stmt = oci_parse($conn, "SELECT LOCATIONNAME from DATABASE where LOCATIONNAME like :s and AKTIV = 'Y'")){ 
    $param_term = '%' . $_REQUEST['term'] . '%';  
    oci_bind_by_name($stmt , ":s" , $param_term, -1);                 
     if(oci_execute($stmt)){                       
       while(($row = oci_fetch_array($stmt, OCI_BOTH)) != false) {               
        echo "<p>" . $row['LOCATIONNAME'] . "</p>"; # " 
       } 
     } else{ 
      echo "ERROR: Could not able to execute" . $param_term; 
     } 
    } 
    oci_free_statement($stmt);

......

這爲我工作。

請，請，請看在error log file而發展。你有一個語法錯誤，阻止腳本運行。在這種情況下，僅僅有error_reporting(E_ALL);是不會幫助你：

Parse error: syntax error, unexpected end of file in ...

它通過不爲if(isset($_REQUEST['term'])) {關閉}引起的。通過在文件末尾添加一個}來修復它。現在

你會看到兩個警告：

Warning: oci_result() expects exactly 2 parameters, 1 given in ...

在$result = oci_result($stmt);未提供所需的第二個參數引起的。
Warning: oci_num_rows() expects parameter 1 to be resource, boolean given in ...

由不正確地處理返回值if(oci_num_rows($result) > 0){

它看起來像你剛剛更換天真功能mysql與oci功能，而在行爲差異的任何方面引起的。

... 
if (oci_execute($stmt)) { 
    while (($row = oci_fetch_array($stmt, OCI_BOTH)) != false) { 
     // MUST use uppercase column names. 
     echo "<p>" . $row["STANDORTNAME"] . "</p>"; 
    } 
} 
...
