Question

我有一个搜索表单来搜索名字和姓氏。知道我不知道我怎么做才能得到两者的确切结果..

<form action="search1.php" method="GET">
<label for="firstname">Firstname</label>
    <input type="name1" name="query" />
    <label for="lastname">lastname</label>
    <input type="lastname" name="query1" />
    <input type="submit" value="Search" />

现在在数据库来宾中，我的名字为firstname，lastname = lastname。因此，当有人搜索时，我希望它只显示两者是否匹配。

我的search1.php：

＆＃13;

<?php
$query = $_GET['query']; 
$query = $_GET['query1']; 
// gets value sent over search form
 
$min_length = 3;
// you can set minimum length of the query if you want
 
if(strlen($query) >= $min_length){ // if query length is more or equal minimum length then
     
    $query = htmlspecialchars($query); 
    // changes characters used in html to their equivalents, for example: < to &gt;
     
    $query = mysql_real_escape_string($query);
    // makes sure nobody uses SQL injection
     
    $raw_results = mysql_query("SELECT * FROM guests WHERE name1 LIKE "$query" AND lastname LIKE "$query1";") or die(mysql_error());
        
		if(mysql_num_rows($raw_results) > 0){ // if one or more rows are returned do following
         
        while($results = mysql_fetch_array($raw_results)){
         
            echo "<p><h3>".$results['title']."</h3>".$results['text']."</p>";
            // posts results gotten from database(title and text) you can also show id ($results['id'])
        }
         
    }
    else{ // if there is no matching rows do following
        echo "No results";
    }
     
}
else{ // if query length is less than minimum
    echo "Minimum length is ".$min_length;
}
?>

＆＃13;

如果有人可以帮助我会很酷..我知道如何搜索1输入而不是2或3输入需要匹配？

Answer 1

如果你想要完全匹配数据库的两个字段，那么你可以这样做

$raw_results = mysql_query("SELECT * FROM guests WHERE name1='".$query."' AND lastname='".$query1."';") or die(mysql_error());

Answer 2

<form action="search1.php" method="GET">
<label for="firstname">Firstname</label>
    <input type="name1" name="query" />
    <label for="lastname">lastname</label>
    <input type="lastname" name="query1" />
    <input type="submit" value="Search" />

我的search1.php：

<?php
// gets value sent over search form
$query = $_GET['query']; 
$query1 = $_GET['query1'];

if(strlen($query) >= $min_length){ // if query length is more or equal minimum length then

    $query = htmlspecialchars($query); 
    // changes characters used in html to their equivalents, for example: < to &gt;


    $query = mysql_real_escape_string($query);
    // makes sure nobody uses SQL injection

    $raw_results = mysql_query("SELECT * FROM guests WHERE name1 LIKE '".$query."' AND lastname LIKE '".$query1."' ") or die(mysql_error());


        if(mysql_num_rows($raw_results) > 0){ // if one or more rows are returned do following

        while($results = mysql_fetch_array($raw_results)){

            echo "<p><h3>".$results['title']."</h3>".$results['text']."</p>";
            // posts results gotten from database(title and text) you can also show id ($results['id'])
        }

    }
    else{ // if there is no matching rows do following
        echo "No results";
    }


}
else{ // if query length is less than minimum
    echo "Minimum length is ".$min_length;
}
?>

如何使用2个字段的PHP搜索并获得完全匹配？
