我的数据库搜索表单有问题。该页面大部分运行良好,但我收到两个错误。

警告:ociexecute() [function.ociexecute]: ORA-00904: *$search_term*: * */search_results.php 第 53 行的无效标识符

警告:ocifetch() [function.ocifetch]:ORA-24374:在第 70 行的 **/search_results.php 中的 fetch 或执行和 fetch 之前定义未完成

我已经评论了相关的行号。如果有人能告诉我为什么会这样,我将不胜感激:)

编辑:忘了提,尽管输入了应该得到结果的搜索词,但表格什么也没显示

编辑 2:当查询更改为 SELECT * FROM Phones 时,它工作正常。它必须与查询有关。

<?php
    $search_term = $_POST['search_box'];

    /* Set oracle user login and password info */
    $dbuser = "**"; /* your login */
    $dbpass = "**"; /* your oracle access password */
    $db = "**"; 
    $connect = OCILogon($dbuser, $dbpass, $db);

    if (!$connect) {
    echo "An error occurred connecting to the database"; 
    exit; 
    }

    /* build sql statement using form data */
    $query = "SELECT * FROM Phones WHERE Name LIKE ".$search_term;

    /* check the sql statement for errors and if errors report them */
    $stmt = OCIParse($connect, $query);
    echo "SQL: $query<br>";
    if(!$stmt) {
        echo "An error occurred in parsing the sql string.\n"; 
        exit; 
    }
    OCIExecute($stmt); //line 53
    ?>

    <h1 class="green">PHP and Oracle databases</h1>

    while(OCIFetch($stmt)) { //line 70

        $fg1 = OCIResult($stmt,"ID"); //"ID number";
        echo("<td width=75>");
        echo ($fg1);
        echo("</td>");

        echo("<td width=75>");
        echo ($fg4);
        echo("</td>");

        // End the row 
        echo("</tr>");
    } 
    // Close the connection
    OCILogOff ($connect); 
    ?>

看起来您的 SQL 命令需要在您的$search_term内容周围加上引号。

我不知道 PHP,但我想它应该是这样的:

$query = "SELECT * FROM Phones WHERE Name LIKE '%".$search_term."%'"; 

注意添加的撇号(SQL 的引号字符)和百分号(LIKE 的通配符)。我不确定你如何在 PHP 中正确引用撇号(')和百分号(%),所以你应该检查一下。

(对不起,我不知道如何在 Oracle 上进行不区分大小写的搜索,您应该将其作为单独的问题发布。)
