Php 日期范围搜索

嗨，我在我的日期范围搜索中遇到了问题，因为它获取了错误的结果

例如：我正在搜索从2013年1月4日到2013年2月4日的数据，假设结果将显示从2013年1月4日到2013年2月4日这些日期的数据，但它获取了错误的数据

这是我的表格

<form  method="post"id="myform" action="index.php" >
        <label for="from">Sales Date from :</label>
        <input name="startfrom" type="text" id="startfrom" class="datepicker form-control"/>
        <label for="to">Sales Date to :</label>
        <input name="to" type="text" id="end" class="datepicker form-control"/>
        <label>Outlet Name:</label>

            <?php
            error_reporting(0);
            include 'config.php';
                $sql = "SELECT * FROM ".$SETTINGS["data_table"]." GROUP BY OutletName ORDER BY OutletName";
                $sql_result = mysql_query ($sql, $connection ) or die ('request "Could not execute SQL query" '.$sql);
                while ($row = mysql_fetch_assoc($sql_result)) {
                    echo "<option value='".$row["OutletName"]."'".($row["OutletName"]==$_REQUEST["OutletName"] ? " selected" : "").">".$row["OutletName"]."</option>";
                }
            ?>
        </select>
        <label>Category:</label>
        <select name="Category" class="input-sm form-control ">

                while ($row = mysql_fetch_assoc($sql_result)) {

                }
            ?>
        </select></br>
        <label>Product Code:</label>

            $sql = "SELECT * FROM ".$SETTINGS["data_table"]." GROUP BY ProductCode ORDER BY ProductCode";
                $sql_result = mysql_query ($sql, $connection ) or die ('request "Could not execute SQL query" '.$sql);
                while ($row = mysql_fetch_assoc($sql_result)) {
                    echo "<option value='".$row["ProductCode"]."'".($row["ProductCode"]==$_REQUEST["ProductCode"] ? " selected" : "").">".$row["ProductCode"]."</option>";
                }
            ?>

        <button type="submit" class="btn  btn-primary btn-block" name="submit" id="submit"  />FIND&nbsp;<span class="glyphicon glyphicon-search"></span></button>

这是我的搜索查询

谢谢你的改变

<input name="to" type="text" id="end" class="datepicker form-control"/>

如果您正在使用GROUP BY on salesDate字段，请以这种方式使用GROUP BY UNIX_TIMESTAMPstr_to_dateSalesDate，'%d/%m/%Y'

编辑2

替换所有发生的

SalesDate到UNIX\u TIMESTAMPstr\u到\u dateSalesDate，'%d/%m/%Y' 和 $\u请求[startfrom]到 strottimemysql\u real\u escape\u string$\u请求[startfrom] 和 $\u请求[结束]到

---

STROTIMEYMySQL\u real\u escape\u string$\u REQUEST[startfrom]

谢谢我编辑了它没有，但还有一个问题我的SalesDate是varchar如何转换它的datetime或date？这里是$sql=SELECT CategoryID，oracleContegory，str\u to\u dateSalesDate，'%d/%m/%Y'，OutletName，ProductCode，Category，MealType，SUMQuantity AS Quantity1，SUMNetPrice作为来自.$SETTINGS[数据表]的NetPrice 1。其中str_to_datesaledate，'%d/%m/%Y'>='.date'd-m-Y'，strottimemysql_real_escape_string$\u REQUEST[startfrom].'和str_to_datesaledate，'%d/%m/%Y'如果date'd-m-Y'，strottimemysql_real_escape_string$\u REQUEST[startfrom]和date'd-m-Y'，strottimemysql_real_escape_字符串$\u REQUEST[end]，我也会更改此值{如您所说，请将日期'd-m-Y'，…更改为日期'd/m/Y'…以及$search_groupby上的内容？此处$search_groupby=按类别分组ID，OracleCategory，ProductCode ORDER BY CategoryID，OracleCategory，ProductCode；

<input name="end" type="text" id="end" class="datepicker form-control"/>

$sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE UNIX_TIMESTAMP(str_to_date(SalesDate, '%d/%m/%Y')) >= '".strtotime(mysql_real_escape_string($_REQUEST["startfrom"]))."' AND UNIX_TIMESTAMP(str_to_date(SalesDate, '%d/%m/%Y'))<='".strtotime(mysql_real_escape_string($_REQUEST["startfrom"]))."'".$search_OutletName.$search_Category.$search_ProductCode;
