我正在尝试在sql server 2000数据库中保存图像。
该列的数据类型为image
。
我收到以下错误:
错误:警告:odbc_exec() [function.odbc-exec]:SQL错误: [Microsoft] [ODBC SQL Server 驱动程序] [SQL Server]操作数类型冲突: text与图像,SQL不兼容 状态22005在SQLExecDirect中 C:\ xampp \ htdocs \ test \ upload.php on 第25行错误,查询失败
以下是代码:
<?php
include('config.php');
if(is_uploaded_file($_FILES['userfile']['tmp_name']))
{
$fileName = $_FILES['userfile']['name'];
$tmpName = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];
$size = filesize($tmpName);
set_magic_quotes_runtime(0);//to desactive the default escape spacials caracters made by PHP in the externes files
$img_binaire = base64_encode(fread(fopen(str_replace("'","''",$tmpName), "r"), $size));
$query = "INSERT INTO test_image (image_name, image_content, image_size) ".
"VALUES ('{$fileName}','{$img_binaire}', '{$size}')";
odbc_exec($conn, $query) or die('Error, query failed');
echo "<br>File $fileName uploaded<br>";
echo "<br>File Size: $fileSize <br>";
}
?>
<?php
include('config.php');
$sql = "select * from test_image where id =2";
$rsl = odbc_exec($conn, $sql);
$image_info = odbc_fetch_array($rsl);
//$count = sizeof($image_info['image_content']);
//header('Accept-Ranges: bytes');
//header('Content-Length: '.$image_info['image_size']);
//header("Content-length: 17397");
header('Content-Type: image/jpeg');
echo base64_decode($image_info['image_content']);
//echo bindec($image_info['image_content']);
?>
我需要做些什么不同的事情?
答案 0 :(得分:0)
此处至少有一个错误:base64_encode(fread(fopen(str_replace("'","''",$tmpName), "r"), $size));
必须删除str_replace,因为它会破坏您的数据。
也可能存在其他错误。你必须调试你的代码。
