Question

我需要一个php页面的帮助，该页面显示来自mysql数据库的有关城镇广场周围建筑物的信息。我想要它设置，以便地址是最初显示的唯一东西。然后当有人点击某个地址时，会向他们显示有关该特定建筑物的更多信息。

我是PHP的新手。我知道有两种解决方案可行，但除非必须，否则我不想走那条路。

这两个解决方案

为每个建筑创建一个页面，并将每个地址链接到特定页面和
将每个数据库项插入页面（而不是PHP循环）和隐藏的div，可以为每个地址切换。

我现在拥有的代码（并且可以使用）用于显示地址：

   echo "<p><a href="WhatDoIPut???"><h3>   " . stripslashes($rowBuildings[building_address]) . "</h3></a><br>\n";

但是，如果（并且仅当）他们点击建筑物地址，我该如何显示建筑物信息的其余部分？对不起，如果这是一个广泛的话题。我读过几个论坛，但没有运气。我的问题是没有从数据库中获取信息。

Answer 1

我找到了解决我的困境的方法。。

我正在使用Javascript来切换div（这很简单）。我的问题是切换每个单独的div，因为它们是由PHP脚本添加的（根据数据库条目的数量）。我无法弄清楚如何为链接和div提供增量div id名称。示例：

 <!--This was the link to toggle the div --> 
 <a href="#" onclick="toggleMe('divid');"><h3>Address</h3></a>

 <!--This was the div to toggle --> 
 <div id="divid">Hello</div>

我的PHP插入了多个div和链接，所以当你点击一个地址时，所有名为“divid”的div都会出现。为了解决这个问题，我在每个div id中添加了一个PHP变量，例如：

$uniqueID = 0;
$PleaseWork = 0;

然后我放在php代码的底部：

$ UNIQUEID ++; $ PleaseWork ++;

这允许我将变量放在链接中，并将div id一致地计算在一起。总而言之，以下是代码：

Java to toggle

> <script type="text/javascript">
> 
>       function toggleMe(a){ var e=document.getElementById(a); if(!e)return
> true; if(e.style.display=="none"){ e.style.display="block" } else{
> e.style.display="none" } return true } </script>

PHP代码 - 链接＆amp;可见项目

<div class="building" align="left" style="margin-left:100px;">
    <? 
    {
 $uniqueID = 0;
 $PleaseWork = &$uniqueID;
 }
 $selectAddress ="SELECT * FROM `buildings` order by building_address";
 $resultAddress = mysql_query($selectAddress);
  while($rowBuildings = mysql_fetch_array($resultAddress)){;
echo "<p><a id=\"displayText\" href=\"#\" onclick=toggleMe(\"divn$PleaseWork\");><h3>   " . stripslashes($rowBuildings[building_address]) . "</a></h3><br>\n";
   echo "<b>For Sale or Rent:</b> " . $rowBuildings[building_saleorrent] . "";
    if(!empty($rowBuildings[building_permonth]))
      echo "<b>Rent Per Month: </b>" . $rowBuildings[building_permonth] . "";
      if(!empty($rowBuildings[building_saleprice]))
      echo "<b>Sale Price: </b>" . $rowBuildings[building_saleprice] . "";
   echo "<br>\n";

PHP代码 - 隐藏的DIV

   echo "<div id=\"divn$uniqueID\" style=\"display:none\"><b>Is the Property Listed with a Realtor? </b> " . $rowBuildings[building_realtor] . "<br>\n";
        if(!empty($rowBuildings[building_target]))
        echo "<b>Best Suited for Building: </b>" . $rowBuildings[building_target] . "<br>\n";
    echo "<b>Owner: </b>" . $rowBuildings[building_owner] . "";
    if(!empty($rowBuildings[building_ownphone]))
      echo "<b>  Phone: </b>" . formatPhone($rowBuildings[building_ownphone]) . "";
      if(!empty($rowBuildings[building_ownemail]))
      echo "<b>  Email: </b>" . $rowBuildings[building_ownemail] . "";
    echo "<br>\n";
     echo "<b> Is the building occupied? </b>" . $rowBuildings[building_isoccupant] . "<br>\n";
    if(!empty($rowBuildings[building_occupant]))
      echo "<b>Current Occupant:</b>" . $rowBuildings[building_occupant] . "<br>\n";
    if(!empty($rowBuildings[building_occupantphone]))
      echo "<b>Occupant Phone:</b>" . formatPhone($rowBuildings[building_occupantphone]) . "<br>\n";
        echo "<b>Utilities: </b>" . $rowBuildings[building_utilities] . "<br>\n";
        echo "<b>Stories: </b>" . $rowBuildings[building_stories] . "<br>\n";
        echo "<b>Total Sq. Footage: </b>" . $rowBuildings[building_square] . "<br>\n";
        echo "<b>Footage Breakdown:</b><br> ";
    if(!empty($rowBuildings[building_residential]))
      echo "<b>Residental: </b>" . $rowBuildings[building_residential] . " ";
      if(!empty($rowBuildings[building_lightindustry]))
      echo "<b>Light Industrial: </b>" . $rowBuildings[building_lightindustry] . " ";
      if(!empty($rowBuildings[building_commercial]))
      echo "<b>Residental: </b>" . $rowBuildings[building_commercial] . " ";
      echo "<br>\n";
        echo "<b>Storage: </b>" . $rowBuildings[building_storage] . "&nbsp; <b>Storage Sq. Footage:&nbsp; </b>" . $rowBuildings[building_storefoot] . "<br>\n";
        echo "<b>Inside of Building: </b>" . $rowBuildings[building_inside] . "<br>\n";
        echo "<b>Outside of Building: </b>" . $rowBuildings[building_outside] . "<br>\n";
        echo "<b>Parking: </b>" . $rowBuildings[building_parking] . "<br>\n";
         if(!empty($rowBuildings[building_issues]))
      echo "<b>Issues With the Building: </b>" . $rowBuildings[building_issues] . "<br>\n";
       if(!empty($rowBuildings[building_features]))
      echo "<b>Main Features of the Building: </b>" . $rowBuildings[building_features] . "<br>\n";
       if(!empty($rowBuildings[building_notes]))
      echo "<b>Notes on the Building: </b>" . $rowBuildings[building_notes] . "<br>\n";     
    echo "</div></p>";
$uniqueId++;
$PleaseWork++;
}


?>
