Php 无法清除错误mysql\u fetch\u array（）希望参数1是给定的资源、对象

php

Php 无法清除错误mysql\u fetch\u array（）希望参数1是给定的资源、对象,php,mysqli,Php,Mysqli,我正在尝试构建一个SELECT查询，它允许我使用返回结果的表单来处理对所选行的更新。我收到的警告出现在我代码的第36行。我以为我正确地设置了代码来构建表，然后填充它，但是我找不到我的错误。我看到了这个问题的几个版本，但我没有看到一个是关于给定对象的。任何帮助都会受到欢迎 <html> <head> </head> <body> <?php $servername = "localhost"; $username = "xxx"; $passw

将mysql\u fetch\u数组$result更改为$result->fetch\u数组

你不能对mysql和mysqli进行merrage

您使用mysqli_389;连接MYSQL，当您想要得到结果时，仍然需要mysqli_389;

这是官方提供的样本：

`$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if ($mysqli->connect_errno){
    printf("Connect failed: %s\n", $mysqli->connect_error);
    exit();
}
$sql = "SELECT a.uid, a.role AS roleid, b.role,FROM tbl_usr a INNER JOIN tbl_memrole b ON a.role = b.id  ";
    if ($result = $mysqli->query($sql)) { 
        while($obj = $result->fetch_object()){ 
            $line.=$obj->uid; 
            $line.=$obj->role; 
            $line.=$obj->roleid; 
        }
    }
    $result->close(); 
    unset($obj); 
    unset($sql); 
    unset($query);`
除了评论中前面的注释之外。我还没有看到关于HTML元素的任何其他答案/注释，因此我将在这些元素上添加答案

使用此PHP生成的HTML将无效。属性需要被引用，输入元素需要被关闭

例如，您当前的代码

echo "<form action=mynewform.php method=post>";
echo "<tr>"; 
echo "<td>" . "<input type=text name=project value=" . $record['Project'] . " </td>";
应该给你什么

<form action='mynewform.php' method='post'>
<tr>
<td><input type='text' name='project' value='what ever projects value is' /></td>
请注意，第二个示例中的语法突出显示与第一个示例中的不同

另外，请看一看，或一个不太安全的方法，但比你目前拥有的更好

你有一些错误。一个是你把mysql驱动程序和mysqli混合在一起。另一个原因是$connection未定义。您还可以接受SQL注入。a mysql_fetch_数组b mysql_query另外，您的HTML元素无效，您缺少结束标记，您的属性应该被引用。这不是当前的问题，但一旦您得到SQL处理，就会出现。是的，这是我提到的第一个错误；您正在将mysql_uDriver与mysqli混合，因此$result是一个mysqli结果对象；mysql_uu函数无法与之配合使用。看看。$result是一个mysqli查询，所以当$record=mysql\u fetch\u array$result时，不能在中使用mysql\u fetch\u array$result。在$record=$result->fetch_arrayYou需要引用键时尝试，否则php将假定它们是常量。因此，将if-isset$\u POST[update]{更改为if-isset$\u POST['update']{ie.'update'将if$result->num_rows>0移到while$record=$result->fetch_array.Chris之外会更有意义。感谢您的额外输入。我正开始研究为什么我的表单在看到此评论时没有生成任何结果。我知道您的意图，但当我进行更改时，表没有呈现正确。您可以更新您的问题以显示您所做的更改吗？您错过了结束输入元素。请参阅。'/>在我的答案中。vs yours；。好的，表单回来了，但我显示在更新和删除按钮中，它仍然不会向更新查询传递任何内容。我感谢您为解决此问题所提供的所有帮助，但我不希望你不能花一整天的时间来帮我解决这个问题。请用你更新的代码更新这个问题。你的更新查询无效。你缺少“WHERE Project=”的结尾$\u POST[hidden]。这仍然对SQL注入开放。我看不出您在哪里使用删除。您应该在这些查询和页面本身上使用错误报告。
