一次输入多个图像上载PHP表单
我一直在努力使这项工作已经有相当一段时间了。但我似乎不能让它工作。我想有一个多图像上传表单，只使用一个输入 这是我的upload.php一次输入多个图像上载PHP表单,php,image,file-upload,image-uploading,multiple-file-upload,Php,Image,File Upload,Image Uploading,Multiple File Upload,我一直在努力使这项工作已经有相当一段时间了。但我似乎不能让它工作。我想有一个多图像上传表单，只使用一个输入 这是我的upload.php <?php include("../include/session.php"); session_start(); $allowedExts = array("jpeg", "jpg", "png", "gif"); $extension = end(explode(".", $_FILES["upload"]["name"])); if(isset

多个图像上传使用php完整的源代码和预览可在下面的链接。 示例代码：
if (isset($_POST['submit'])) {
$j = 0; //Variable for indexing uploaded image
$target_path = "uploads/"; //Declaring Path for uploaded images
for ($i = 0; $i < count($_FILES['file']['name']); $i++) { //loop to get individual element from the array
$validextensions = array("jpeg", "jpg", "png"); //Extensions which are allowed
$ext = explode('.', basename($_FILES['file']['name'][$i])); //explode file name from dot(.)
$file_extension = end($ext); //store extensions in the variable
$target_path = $target_path.md5(uniqid()).
".".$ext[count($ext) - 1]; //set the target path with a new name of image
$j = $j + 1; //increment the number of uploaded images according to the files in array
if (($_FILES["file"]["size"][$i] < 100000) //Approx. 100kb files can be uploaded.
&& in_array($file_extension, $validextensions)) {
if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) { //if file moved to uploads folder
echo $j.
').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
} else { //if file was not moved.
echo $j.
').<span id="error">please try again!.</span><br/><br/>';
}
} else { //if file size and file type was incorrect.
echo $j.
').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
}
}
}
这里$file\u name\u all和$filepath两次获得1个上传文件名？多路径图像与其他表上传 $sql1=插入eventtitle值“$title”
$result1 = mysqli_query($connection,$sql1) or die(mysqli_error($connection));
$lastid= $connection->insert_id;
foreach ($_FILES["file"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK ){
$name = $lastid.$_FILES['file']['name'][$key];
$target_dir = "photo/";
$sql2 = "INSERT INTO photos(image,eventid) VALUES ('".$target_dir.$name."','".$lastid."')";
$result2 = mysqli_query($connection,$sql2) or die(mysqli_error($connection));
move_uploaded_file($_FILES['file']['tmp_name'][$key],$target_dir.$name);
}
}
$query = "SELECT * FROM event ";
$result = mysqli_query($connection,$query) or die(mysqli_error());
if($result->num_rows > 0) {
while($r = mysqli_fetch_assoc($result)){
$eventid= $r['id'];
$sqli="select id,image from photos where eventid='".$eventid."'";

}
$msg1[] = array ("imagelist" => $image_json_array);
}
}}注意此链接以及如何将这些图像保存到数据库？@AsifMehmood将图像作为blob文件保存到数据库中确实不是一个好主意，除非您正在处理一个小型且不寻求SEO的项目。@AsifMehmood请看这里：为什么要使用extract$\u POST？我删除了它，代码运行良好。而$\u POST上的摘录似乎是糟糕的编码实践。您可以在php.net manual@PreciousTom中找到“请勿对不受信任的数据使用提取”的警告，如用户输入，即$\u GET、$\u文件等。那么，还有什么办法不将图像保存到数据库？这是问题的答案吗？如果是这样，请明确说明它解决问题的程度。如果这本身就是一个问题，请在此处删除它并询问一个新问题。我只想添加到这个问题中，初始$target_path变量需要位于for循环中，否则通过md5散列的文件名将被连接。此外，我删除了散列文件名方法，因为它不适合我的需要。
