以HTML格式返回PHP / MySQL结果以进行编辑

Question

I have a database that users can search by any number of predetermined fields (chosen from a drop down). The problem I'm having is being able to edit existing records. The first script prompts for the record ID to edit. If no record is found the user is told to try again.

When a record is found the results are suppose to display in HTML input boxes. The user can then modify the data, hit submit and the record updates (another script).

Enabled errors. This is what is thrown:

Fatal error: Call to undefined method mysqli_result::fetch__assoc() in (path to script) on line 37

Any ideas on what is wrong?

<?php
    //Include everything but the password to connect to db
    include 'includes/connect_pw.php';

    //User supplies password on previous form
    $dbpass = $_POST['password'];     

    //User supplies id on previous form
    $rec_id = $_POST['query'];

    //Create connection to database using mysqli
    $conn = new mysqli($dbhost, $dbuser, $dbpass, $db);

    //Check connection. If error then kill process, show error and tell user to retry
    if ($conn->connect_error) {
        die ("<br><br>" . $conn->connect_error . "<p></p>Did you forget the password?");
    }

    //If no error then set select statement as variable 
    $sql = "SELECT * FROM dcr_master
            WHERE (`ID` = '".$rec_id."')";
    //Pass select ($sql) into connection ($conn) with result to ($result)
    //Set new variables to populate input boxes.  ex: $variable = $row['record field']
    $result = $conn->query($sql);

    if ($result->num_rows >=1) {
        while ($row = $result->fetch__assoc()) {
            $Server_Name = $row['Server_Name'];
            $Description = $row['Description'];
            $IP_Address = $row['IP_Address'];
            $Wiki_Link = $row['Wiki_Link'];

        }
?>
<form action="modify_dcr_3.php" method="POST">
    <input type="hidden" name="ID" value="<?=$rec_id;?>">
Server Name<input type="text" name="Server_Name" value="<?=$Server_Name;?>">
Description<input type="text" name="Description" value="<?=$Description;?>">
IP_Address<input type="text" name="IP_Address" value="<?=$IP_Address;?>">
Wiki_Link<input type="text" name="Wiki_Link" value="<?=$Wiki_Link;?>">
    <input type="submit">
</form>
<?php
        }
    else    {
        echo "<rb><br>No matching ID found.
              <p></p>Try again. Just don't use " .$rec_id. " OK?";
    }   
?>

You have a double underscore on fetch__assoc() , this should have only a single underscore: fetch_assoc() . Specifically change this:

    while ($row = $result->fetch__assoc()) {
        ...
    }

To:

    while ($row = $result->fetch_assoc()) {
        ...
    }
