Php Mysql 组合框星号 PMS

Question

大家好，

我需要一些 php 和 MySQL 查询方面的帮助。我有一个来自 GitHub 的人制作的应用程序，我想根据自己的需要进行一些修改。该应用程序是来自 pbxinaflash 的 FIAS-PMS，您可以为一个分机签入、签出和设置唤醒呼叫。目标是为办公室和客人使用的分机创建不同的报告。为客人工作完美。

代码如下所示：

$dbconnection = mysql_connect($dbhost, $dbuser, $dbpass) or die("Database connection failed");
    mysql_select_db($dbname) or die("data base Hotel-Rooms open failed");

         $query = "SELECT `ID`, `Desc` FROM `Rooms` ORDER BY `Desc` ASC";
         $result = mysql_query($query) or die ("Couldn't execute SQL query on Hotel-Users table.") ;
    mysql_close($dbconnection);
    echo " <SELECT ID=\"RoomsComboBox\" NAME=\"RoomsComboBox\">";
    echo "<OPTION VALUE=\"ALL\" SELECTED> ".$SecLab22." </OPTION>";
    while ($row = mysql_fetch_array($result))  {
    echo "<OPTION VALUE=\"$row[0]\">" . $row[1] . "</OPTION>";
    }
    echo "</SELECT>";
echo "</TD>" ;
echo "<TD><INPUT TYPE=\"SUBMIT\" NAME=\"SearchButton\" VALUE=\"".$SecLab21."\"></TD>\n" ;
echo "</TR>\n" ;
echo "</TABLE></div>\n";
echo "</FORM>\n";

if(isset($_POST['SearchButton'])) :


echo

 "<TABLE cellSpacing=0 cellPadding=0 width=900 border=0>\n" ;
echo "<TR><TD>Id</TD><TD>".$SecLab7."</TD><TD>".$SecLab14."</TD><TD>".$SecLab15."</TD><TD>".$SecLab17."</TD><TD>".$SecLab31."</TD><TD>".$SecLab1."</TD>" ;
    $dbconnection 

= mysql_connect($dbhost, $dbuser, $dbpass) or die("Database connection failed");
    mysql_select_db($dbname) or die("data base Hotel-Rates open failed");

    $between = '';
    $room = '';

        $query = "SELECT * FROM `Users`";
        $RoomsComboBox = $_POST['RoomsComboBox'];

    $FROMD = $_POST['FROMD'] ;
    $FROMM = $_POST['FROMM'] ;
    $FROMY = $_POST['FROMY'] ;

    $TOD = $_POST['TOD'] ;
    $TOM = $_POST['TOM'] ;
    $TOY = $_POST['TOY'] ;

    if ($RoomsComboBox !== 'ALL') {
        $room = " `Room` = '" . $RoomsComboBox . "'";
    }

    if ($FROMD !== '' AND $FROMM !== '' AND $FROMY !== '') {
        $from = " `Checkout` >= '" . $FROMY . "-" . $FROMM . "-" . $FROMD . "'";
        if ($TOD !== '' AND $TOM !== '' AND $TOY !== '') {
            $to = " AND `Checkout` <= '" . $TOY . "-" . $TOM . "-" . $TOD . "'";
        }
    $between = $from . $to;
    }


    If ($between !== '' OR $room !== '') {
        $query = $query . " WHERE" ;
    }

    If ($between !== '' AND $room !== '') {
        $query = $query . $between . " AND" . $room;
    }

    If ($between !== '' AND $room == '') {
        $query = $query . $between;
    }

    If ($between == '' AND $room !== '') {
        $query = $query . $room;
    }

    $query = $query . " ORDER BY ID DESC";
    //printf($query);

我做了什么： 来自

$query = "SELECT `ID`, `Desc` FROM `Rooms` ORDER BY `Desc` ASC" ;

到

$query = "SELECT `ID`, `Desc` FROM `Rooms` WHERE `Desc` = 'Frontoffice' OR `Desc` = 'Backoffice' OR `Desc` = 'Manager' ORDER BY `Desc` ASC" ;

来自

$query = "SELECT * FROM `Users`";

到

$query = "SELECT `ID`, `Desc` FROM `Rooms` WHERE `Desc` = 'Frontoffice' OR `Desc` = 'Backoffice' OR `Desc` = 'Manager' ORDER BY `Desc` ASC" ;

部分工作正常，我只能在组合框中看到办公室扩展，如果我从下拉列表中窥视“全部”，我可以搜索，但如果我选择其他内容，例如 Frontoffice 并单击搜索，则页面正在重播，但出现一个错误。

日期搜索根本不起作用。 我必须建议你们，我不知道 php 和 MySQL 只是一些非常基础的知识:) 请问有人可以帮我一些语法吗？ 非常感谢。

在此处输入代码

Answer 1

您的第一个查询可以简化：

$query = "SELECT `ID`, `Desc` FROM `Rooms` WHERE `Desc` IN ( 'Frontoffice', 'Backoffice', 'Manager') ORDER BY `Desc` ASC" ;

第二个查询没有显示何时以及如何执行，但它是针对Users 和 NOT Rooms，所以你不能使用同一行。您需要分析表格并进行调整。

Answer 2

谢谢。你是对的，在我尝试的第二个查询中，这是我的错误：

$query = "SELECT * FROM `Users` WHERE `Desc` = 'Frontoffice' OR `Desc` = 'Backoffice' OR `Desc` = 'Manager' " ;

同样的结果。我无法从结帐日期开始搜索，该网站显示查询错误。

Answer 3

我错误地错过了代码的最后一部分。

$query = $query . " ORDER BY ID DESC";
    //printf($query);

    $result = mysql_query($query) or die("Web site query failed");
    mysql_close($dbconnection);
    while ($row = mysql_fetch_array($result)) {
    echo "<TR><TD><FONT face=verdana,sans-serif>" . $row["ID"] . "</TD><TD>" . $row["Desc"]  . "</TD><TD>" .$row["Name"] ."</TD><TD>" . $row["Checkin"] . "</TD><TD>" . $row["Checkout"] . "</TD><TD>" . $row["Total"] . "</TD><TD><a href=\"ec.php?Ext=" .$row["Ext"] . "&Checkin=" . $row["Checkin"] . "&Checkout=" . $row["Checkout"] ."\">".$SecLab29."</a></TD></TR>\n" ;
    }
echo "</TABLE>\n";
endif;
