Question

我有一个MySQL数据库，我需要搜索交易号码（它显示我的姓名，电子邮件和item_name）或搜索我的电子邮件地址和名称和购买日期，然后我会给我交易号码和item_name - 除非电子邮件，姓名和购买日期都正确，否则我不希望出现任何问题。

我的数据库中的字段是：

iname
iemail
itransaction_id
item_name

有人可以帮忙.... 这就是我现在拥有的......

<html>

<head>
<title>Search</title>
</head>

<body bgcolor=#ffffff>

<h2>Search</h2>

<form name="search" method="post" action="findme.php">
Seach for: <input type="text" name="find" /> 


<input type="submit" name="search" value="Search" />
</form>

</body>

</html>

另存为findme.html

下：

<html>
<head><title>Searching for a student...</title>
</head>
<body bgcolor=#ffffff>

<?php

echo "<h2>Search Results:</h2><p>";

//If they did not enter a search term we give them an error
if ($find == "")
{
echo "<p>You forgot to enter a search term!!!";
exit;
}

// Otherwise we connect to our Database
mysql_connect("xxxx.com", "xxxx", "xxxxpw") or             die(mysql_error());
mysql_select_db("xxxx") or die(mysql_error());

// We perform a bit of filtering
$find = strtoupper($find);
$find = strip_tags($find);
$find = trim ($find);

//Now we search for our search term, in the field the user specified
$iname = mysql_query("SELECT * FROM ibn_table WHERE upper($field) LIKE'%$find%'");

//And we display the results
while($result = mysql_fetch_array( $iname ))
{
echo $result['firstname'];
echo " ";
echo $result['lastname'];
echo "<br>";
echo $result['idnumber'];
echo "<br>";
echo "<br>";
}

//This counts the number or results - and if there wasn't any it gives them a     little     message explaining that
$anymatches=mysql_num_rows($iname);
if ($anymatches == 0)
{
echo "Sorry, but we can not find an entry to match your query...<br><br>";
}

//And we remind them what they searched for
echo "<b>Searched For:</b> " .$find;
//}
?> 


</body>
</html>

保存为findme.php

这是我目前得到的错误：

Answer 1

SELECT * FROM ibn_table WHERE itransaction_id LIKE '%$find%'
请注意LIKE和'％$ find％'

之间的空格

            // We perform a bit of filtering
            $find = strtoupper($find);
            $find = strip_tags($find);
            $find = trim ($find);

            //Now we search for our search term, in the field the user specified
            $iname = mysql_query("SELECT * FROM ibntable WHERE name LIKE'%$find%'")
             or die(mysql_error());

            //And we display the results
            while($result = mysql_fetch_array( $iname ))
            {
            echo "id :" .$result['fname'];
            echo "<br> ";
            echo "name :".$result['lname'];
            echo "<br>";
            echo "name :".$result['middlename'];
            echo "<br>";
            echo "<br>";
            }

            //This counts the number or results - and if there wasn't any it gives them a     little     message explaining that
            $anymatches = mysql_num_rows($iname);
            if ($anymatches == 0)
            {
            echo "Sorry, but we can not find an entry to match your query...<br><br>";
            }

            //And we remind them what they searched for

            //}


            }
            ?>

Answer 3

就像后续行动一样，我有同样的错误（php脚本显示为文本）和我修复它的方式是我检查了我用于我的网页的网址（这假设我正在运行我的WAMP来自我的本地电脑）。

您应该通过'localhost / somewebpage.html'格式而不是'file：/// C：/wamp/www/somewebpage.html'格式访问您的网页。如果从系统托盘中的WAMP服务器菜单转到www文件夹并双击您尝试运行的html页面，它将打开到'file：/// C：/wamp/www/somewebpage.html '格式。

很明显，解决这个问题的方法是打开浏览器并手动输入“localhost / somewebpage.html”来查看webapge。以这种方式运行它会强制它运行可以处理php的Apache服务器。以另一种方式运行它会强制页面完全从浏览器运行，并且您的Web浏览器不是Web服务器，因此它将php脚本作为纯文本处理并显示在您的页面上。
