php - 将查询结果保存到 session 数组时显示的数据不正确

Question

我设置了以下 php 页面来查询数据库并将结果保存到 session 变量数组中:

<?php
include 'newCustomer.php';
connect('final');


    $query = $_POST['searchDB']; 
    $query = htmlspecialchars($query); // stop HTML characters
    $query = mysql_real_escape_string($query); //stop SQL injection
    $data = mysql_query("SELECT * FROM customer WHERE First_Name LIKE '$query'") ;//query the DB with search field in colleumn selected//


    if($data === FALSE) {
    $error = 'Query error:'.mysql_error();
    echo $error;
    }
    else
    {
    $test = array();
    $colNames = array();
    while($results = mysql_fetch_assoc($data)){// puts data from database into array, loops until no more

    $test[] = $results;

        }
         $anymatches=mysql_num_rows($data); //checks if the querys returned any results
        if ($anymatches != 0) {
        $_SESSION['names']=$test;

    $colNames = array_keys(reset($test));


    }

            if ($anymatches == 0) 
                    { 
                        echo "Sorry, but we can not find an entry to match your query<br><br>"; 
                    } 

    } 
?>

...在不同的页面上执行以下操作，使用 session 变量中的结果创建组合框:

<?php


if (isset($_SESSION['names'])){
echo "Customers";
 $array1 = $_SESSION['names'];
echo'<select name="customers>';
foreach($array1 as $name){
echo'<option value="'.$name.'">'.$name.'</option>';
}
echo'</select>';


}

?>

按下主页上的按钮时会调用查询页面。它创建了组合框。然而，里面只有一遍又一遍的“数组”两个字。为什么它不显示我的数据库中 First_Name 的内容？

谢谢

在输出循环中尝试用“用户名”替换您希望显示的字段名称。

foreach($array1 as $name){
    echo'<option value="'.$name["username"].'">'.$name["username"].'</option>';
}
