Search form syntax rules for Imperial CMS_PHP tutorial

Empire CMS provides a relatively powerful search result call. You can create most of the search functions that meet your needs according to the empire cms search form creation syntax. If you have custom fields in your database, you may need to change the data processing of e/search/index.php for form submission. You can refer to the example provided at the end of the article. Let’s take a look at the search form variable description first:

Variable name	Description	Example

	GET method:/e/search/?searchget=1	/e/search/?searchget=1&keyboard=Empire&show=title

Search special fields	id: Search by message ID keyboard: Search by keyword (can list information by tags) userid : Search by publisher user ID username: Search by publisher username

Here is an example:

<table width="320" border="0" cellspacing="1" cellpadding="3">
<form name="searchform" method="post" action="/e/search/index.php">
<tr>
   <td>关键字：<input name="keyboard" type="text" size="10"></td>
   <td>范围：
      <select name="show">
      <option value="title">标题</option>
      <option value="smalltext">简介</option>
      <option value="newstext">内容</option>
      <option value="writer">作者</option>
      <option value="title,smalltext,newstext,writer">搜索全部</option>
       </select></td>
</tr>
<tr>
   <td>栏　目:
      <select name="classid">
      <option value="0">搜索全部</option>
      <option value="1">新闻中心</option>
      <option value="4">技术文档</option>
      <option value="22">下载中心</option>
       </select> </td>
   <td><input type="submit" name="submit" value="搜索"></td>

</form>
</table>

Search form multi-condition parallel search syntax description

1. Multi-field parallel search: There are two transmission methods: "string" and "array"

String passing as example:

<input type="hidden" name="hh" value="LK">
<input type="hidden" name="show" value="title,writer">
<input type="hidden" name="keyboard" value="标题,作者">

Note: The above is a fuzzy query for information that the title field contains the "title" character or the writer field contains "author"

Array passing as example:

<input type="hidden" name="hh" value="LK">
<input type="hidden" name="show[]" value="title">
<input type="hidden" name="keyboard[]" value="标题">
<input type="hidden" name="show[]" value="writer">
<input type="hidden" name="keyboard[]" value="作者">

The above is a fuzzy query for information that the title field contains the "title" character or the writer field contains "author"

2. Parallel search of multiple logical operation connectors

String passing as example:

<input type="hidden" name="hh" value="LK,EQ">
<input type="hidden" name="show" value="title,writer">
<input type="hidden" name="keyboard" value="标题,作者">

Explanation: The above is a fuzzy query for information that the title field contains the "title" character or the writer field is equal to "author"

String passing as example:

<input type="hidden" name="show[]" value="title">
<input type="hidden" name="hh[]" value="LK">
<input type="hidden" name="keyboard[]" value="标题">
<input type="hidden" name="show[]" value="writer">
<input type="hidden" name="hh[]" value="EQ">
<input type="hidden" name="keyboard[]" value="作者">

Explanation: The above is a fuzzy query for information that the title field contains the "title" character or the writer field is equal to "author".

A practical example

The form design is as follows:

						<form action="[!--news.url--]e/search/index.php" method="post" name="searchform" id="searchform">
						<select name="classid" id="" style="display:none">
							<option value="59,60,78,79,80,81" selected>全部</option>
						</select>
						<input type="hidden" name="show" value="title,myarea,mycategory,smalltext" />
						<input type="hidden" name="tempid" value="1" />
						<table width="100%" cellspacing="0" cellpadding="0" border="0">
							<tbody>
								<tr class="even">
									<td style=" text-align:left;">地区：
								<select name="area" id="">
									<option value="">不限</option>
									<option value="香洲">香洲</option>
									<option value="吉大">吉大</option>
									<option value="拱北">拱北</option>
									<option value="新香洲">新香洲</option>
									<option value="前山">前山</option>
									<option value="南屏">南屏</option>
									<option value="金湾">金湾</option>
									<option value="斗门">斗门</option>
								</select>
								
								  房型：
								<select name="category" id="">
									<option value="">不限</option>
									<option value="58_0">一房</option>
									<option value="58_1">二房</option>
									<option value="58_2">三房以上</option>
									<option value="58_3">公寓</option>
									<option value="58_4">写字楼</option>
									<option value="58_5">商铺</option>
									<option value="58_6">厂房</option>
								</select>
									</td>
									<td> </td>
								</tr>
								<tr class="even">
									<td style=" text-align:left;">时间范围： <input name="starttime" type="text" value="2008-08-08" size="12" onclick="calendar.show(this);" /> 到 <input type="text" id="todayButton" name="todayButton" value="" size="12" onclick="calendar.show(this);" /> （不选则不限时段）</td>
									<td> </td>
								</tr>
								<tr class="even">
									<td style=" text-align:left;"><input name="keyboard" type="text" size="32" value="" id="keyboard" class="inputText" />   <input type="submit" name="Submit22" value=" 搜 索 " /></td>
									<td></td>
								</tr>
							</tbody>
						</table>
						</form>

In order to add the search for the custom fields myarea and mycategory, we need to rewrite e/search/index.php appropriately:

$keyboard=$_POST['keyboard'].','.$_POST['area'].','.$_POST['category'];
// 这是原来的：$keyboard=$_POST['keyboard'];
$keyboardone=0;
if(is_array($keyboard))
{}
elseif(strstr($keyboard,','))
{
	$keyboard=explode(',',$keyboard);
}
else
{
	$keyboard=trim($keyboard);
	$len=strlen($keyboard);
	if($len<$public_r[min_keyboard]||$len>$public_r[max_keyboard])
	{
		printerror("MinKeyboard",$getfrom,1);
	}
	$keyboardone=1;
}

OK, done.
