Question

首先我从MYSQl获取数组，当Ajax显示更改值结果时我有选择输入

echo "<select onchange='showUser(this.value)'> <option>Select Unit</option>";

                            $query="select * from item_units WHERE item_id='".$item_id."'";
                            $res=mysql_query($query);
                            if(!$res){die(mysql_error());}
                            while($row=mysql_fetch_array($res)){
                            $item_unit =$row['item_unit'];

                            $query4 = "SELECT unit_name FROM unit WHERE unit_id='".$item_unit."'";
                            $rest4 = mysql_query($query4);
                            if(isset($rest4))
                            $unit_name4 = mysql_result($rest4, 0); 
                            echo "<option value='$item_unit'>$unit_name4</option>";
                            }

                            echo"</select><br /> ";

然后我从mysql中获取$ item_id

$query="select * from items WHERE item_id='".$item_id2."'";
                            $res=mysql_query($query);
                            if(!$res){die(mysql_error());}
                            while($row=mysql_fetch_array($res)){
                            $item_id=$row['item_id'];}

然后使用

echo"<script>

function showUser(str) {
if (str == '') {
    document.getElementById('txtHint').innerHTML = '';
    return;
} else { 
    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    } else {
        // code for IE6, IE5
        xmlhttp = new ActiveXObject('Microsoft.XMLHTTP');
    }
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
            document.getElementById('txtHint').innerHTML = xmlhttp.responseText;
        }
    }
    xmlhttp.open('GET','myesso.php?id=$item_id&q='+str,true);
    xmlhttp.send();
}

} “;

但ID = $ item_id的值没有值因为OF值超过每条记录的值

我如何解决它我可以将它作为阵列发送吗？

Myesso.php

Myesso.php 

     <?php
      session_start();
      include "config.php";
      $q = intval($_GET['q']);
      $gid = $_REQUEST['id'];
      $moha = $_SESSION['logid'];

      $query="select * from login WHERE login_id='".$moha."'";
      $res=mysql_query($query);
      if(!$res){die(mysql_error());}
      while($row=mysql_fetch_array($res)){
      $type =$row['type'];
      $permission =$row['permission'];
       }

     if($type==1){
     $query="select * from client WHERE login_id='".$moha."'";
     $res=mysql_query($query);
     if(!$res){die(mysql_error());}
     while($row=mysql_fetch_array($res)){
     $level_id =$row['level_id'];
     $area_id =$row['area_id'];
     }
     }elseif($type==2){
     $query="select * from department WHERE login_id='".$moha."'";
     $res=mysql_query($query);
     if(!$res){die(mysql_error());}
     while($row=mysql_fetch_array($res)){
     $level_id =$row['level_id'];
     $area_id =$row['area_id'];
     }  
     }elseif($type==3){
     $query="select * from clerk WHERE login_id='".$moha."'";
     $res=mysql_query($query);
     if(!$res){die(mysql_error());}
     while($row=mysql_fetch_array($res)){
     $level_id =$row['level_id'];
     $area_id =$row['area_id'];
     }  
     }

     $sql="SELECT * FROM item_price WHERE unit_id='".$q."' && level_id = '".$level_id."' && area_id ='".$area_id."' && item_id='".$gid."' ";
     $result = mysql_query($sql);
        while($rows = mysql_fetch_array($result)) {
    $price = $rows['price'];    
   echo"<span class='item-price-special'>$price</span>";
    }


    mysql_close();
     ?>

试试这个替换所有的mywishlist.php

<?php

                        $query2="select * from wishlist WHERE client_id='".$client_id."'";
                        $res2=mysql_query($query2);
                        if(!$res2){die(mysql_error());}
                        while($rows=mysql_fetch_array($res2)){
                        $item_id2 =$rows['item_id'];



                        $query="select * from items WHERE item_id='".$item_id2."'";
