php中实现搜索框
我做出来的网页效果是这样的:

怎样才能更具搜索框中的关键字在第二个页面显示搜索结果呢?

我的代码如下:
这是html的代码:

<br /> <form method="post" action="result.php" class="search"><br /><input type="text" size="30"  id="inputString" onkeyup="lookup(this.value);" onblur="fill();" /><br /><input type="submit" value="搜索" id="send" /><br /><div class="suggestionsBox" id="suggestions"   style="max-width:90%"><br />				<img src="../images/upArrow.png"   style="max-width:90%" alt="upArrow" /><br />				<div class="suggestionList" id="autoSuggestionsList"><br />					 <br />				</div><br /></form><br /><scripit><br />function lookup(inputString) {<br />		if(inputString.length == 0) {<br />			// Hide the suggestion box.<br />			$('#suggestions').hide();<br />		} else {<br />			$.post("rpc.php", {queryString: ""+inputString+""}, function(data){<br />				if(data.length >0) {<br />					$('#suggestions').show();<br />					$('#autoSuggestionsList').html(data);<br />				}<br />			});<br />		}<br />	} // lookup<br />	<br />	function fill(thisValue) {<br />		$('#inputString').val(thisValue);<br />		setTimeout("$('#suggestions').hide();", 200);<br />	}<br /></script><br />
Copy after login

这是rpc.php的文件:

<br><?php <br />require_once 'db_fns.php';<br>header("Content-type: text/html; charset=gb2312");<br>$db = db_connect();<br>if(!$db) {<br>	// Show error if we cannot connect.<br>	echo 'ERROR: Could not connect to the database.';<br>} else {<br>	// Is there a posted query string?<br>	if(isset($_POST['queryString'])) {<br>		$queryString = $db->real_escape_string($_POST['queryString']);<br>			<br>		// Is the string length greater than 0?<br>			<br>		if(strlen($queryString) >0) {<br>			// Run the query: We use LIKE '$queryString%'<br>			// The percentage sign is a wild-card, in my example of countries it works like this...<br>			// $queryString = 'Uni';<br>			// Returned data = 'United States, United Kindom';<br><br>			// YOU NEED TO ALTER THE QUERY TO MATCH YOUR DATABASE.<br>			// eg: SELECT yourColumnName FROM yourTable WHERE yourColumnName LIKE '$queryString%' LIMIT 10<br><br>			$query = $db->query("SELECT * FROM bbstopic WHERE title LIKE '%$queryString%' LIMIT 10");<br>			if($query) {<br>				// While there are results loop through them - fetching an Object (i like PHP5 btw!).<br>				while ($result = $query ->fetch_object()) {<br>					// Format the results, im using 
Copy after login
  •  for the list, you can change it.
    // The onClick function fills the textbox with the result.

    // YOU MUST CHANGE: $result->value to $result->your_colum
    echo '
  • title.'\');">'.$result->title.'
  • ';
    }
    } else {
    echo 'ERROR: There was a problem with the query.';
