Question

我正在做一个网站，我有2个不同的页面使用类似的代码，但只有1个可以工作，另一个似乎有错误“trim（）期望参数1是字符串，对象在”...中给出

editimage.php链接到search.php链接到imagetoupdate.php
updateaccount.php链接到searchEmail.php，链接到accounttoupdate.php

可行的（updateaccount.php）：

<form action="searchEmail.php" method="post">
<input type="text" name="email" style="color:#000000" placeholder="Enter email" />
<input type="submit" name="submit" style="color:#000000" value="Search">
</form>

可行的（searchEmail.php）：

$email = $_POST['email'];
$emailTrim = trim($email);

$sql = "SELECT * FROM account WHERE Email = '$emailTrim'";

$search = mysqli_query ( $conn, $sql);

$emailfound = mysqli_num_rows($search);
        if($emailfound >= 1)
        {
            $_SESSION['MM_email'] = $email;
            header("Location:accountToUpdate.php");
        }
        else{
            echo 'Email not found';
        }

可行的（accounttoupdate.php）：

$email = $_SESSION['MM_email'];
$emailTrim = trim($email);

$sql = "SELECT * FROM account WHERE Email = '$emailTrim'";

$account = mysqli_query ( $conn, $sql);

不可行（editimage.php）：

<form action="search.php" method="post">
<input type="text" name="search" style="color:#000000" placeholder="Enter email/photo no./date" />
<input type="submit" name="submit" style="color:#000000" value="Search">
</form>

不可行（search.php）：

$search = $_POST['search'];
$searchTrim = trim($search);

$sql = "SELECT * FROM upload_data WHERE UploadedBy = '$searchTrim' OR  photoNo = '$searchTrim' OR Datetime LIKE '%$searchTrim%'";

$search = mysqli_query ( $conn, $sql);

$searchfound = mysqli_num_rows($search);
        if($searchfound >= 1)
        {
            $_SESSION['MM_image'] = $search;
            header("Location:imageToUpdate.php");
        }
        else{
            echo 'Invalid input';
        }

不可行（imagetoupdate.php）：

$search = $_SESSION['MM_image'];
$searchTrim = trim($search);

$sql = "SELECT * FROM upload_data WHERE UploadedBy = '$searchTrim' OR  photoNo = '$searchTrim' OR Datetime LIKE '%$searchTrim%'";

$image_list = mysqli_query ( $conn, $sql);

Answer 1

我认为问题在于search.php。我想说你需要改变这个：

$_SESSION['MM_image'] = $search;

到此：

$_SESSION['MM_image'] = $searchTrim;

trim（）期望参数1是字符串，php
