Question

我是php新手，我在后端用XAMPP测试了这段代码

$name = addslashes ($_POST['name']);
$email = addslashes ($_POST['email']);
$paswd = addslashes ($_POST['paswd']);

$sql = "INSERT INTO webusers (username,email,paswd)VALUES('$name','$email','$paswd')";

这是我显示数据的代码 include_once（＆＃39; dbcon.php＆＃39）;

$db = mysql_select_db('test');

$sql = "SELECT * FROM webusers";

$result = mysql_query($sql);
$urow = mysql_num_rows($result);

    echo"
        <table border='1'>

        <th>ID</th>
        <th>USERNAME</th>
        <th>EMAIL</th>
        <th>PASSWORD</th>
 ";

 if($result > 0){
 while($urow = mysql_fetch_array($result)){



    echo "<tr>";
    echo"   <td class='myinput'>'" .$urow['id']. "'</td>";
    echo"   <td class='myinput'>'" .$urow['username']. "'</td>";
    echo"   <td class='myinput'>'" .$urow['email']. "'</td>";
    echo"   <td class='myinput'>'" .$urow['paswd']. "'</td>";
    echo "</tr>";   

    echo"</table>";
    }
    }else{

echo"No record";

    }
  ?>

这些代码有效，除了让我感到惊讶的数据，当我在桌子上显示/显示它时，为什么它有一个单引号。虽然我用html输入数据。而且我的magic_quote_gpc已关闭。有什么我错过或我的代码有什么问题？或者我的数据库整理有什么东西？

我也试过mysql_real_escape_string和mysql_escape_string，没有改变。

感谢您的帮助。

Answer 1

您正在HTML标记

中围绕您的值打印'

echo "<tr>";
echo"   <td class='myinput'>" .$urow['id']. "</td>";
echo"   <td class='myinput'>" .$urow['username']. "</td>";
echo"   <td class='myinput'>" .$urow['email']. "</td>";
echo"   <td class='myinput'>" .$urow['paswd']. "</td>";
echo "</tr>";

是你真正想要回应的

Answer 2

因为你把单引号放在HTML中？

echo"
        <table border='1'>
       <tr>
        <th>ID</th>
        <th>USERNAME</th>
        <th>EMAIL</th>
        <th>PASSWORD</th>
       </tr>
 ";

 if($result > 0){
 while($urow = mysql_fetch_array($result)){



    echo "<tr>";
    echo"   <td class=\"myinput\">" .$urow['id']. "</td>";
    echo"   <td class=\"myinput\">" .$urow['username']. "</td>";
    echo"   <td class=\"myinput\">" .$urow['email']. "</td>";
    echo"   <td class=\"myinput\">" .$urow['paswd']. "</td>";
    echo "</tr>";   

    echo"</table>";
    }
    }else{

echo"No record";

    }

试试，你的代码没有单引号

Answer 3

试试这个

if($result > 0){
 while($urow = mysql_fetch_array($result)){



    echo "<tr>";
    echo"   <td class='myinput'>" .stripslashes($urow['id']). "</td>";
    echo"   <td class='myinput'>" .stripslashes($urow['username']). "</td>";
    echo"   <td class='myinput'>" .stripslashes($urow['email']). "</td>";
    echo"   <td class='myinput'>" .stripslashes($urow['paswd']). "</td>";
    echo "</tr>";   

    echo"</table>";
  }
}else{

echo"No record";

}

为什么mysql数据在PHP中显示时会有单引号？
