我正在尝试插入具有相同 last_id 的多个图像但是我遇到了一个问题，代码不完全符合我的要求他们应该获取最后的 id 并在图像的表格中使用它们，而且每个图像都将具有唯一的图像 Id。在 user 表中 user_id 作为主键，在 image 表中 user_id 作为 fk 和 image_d pk 。下面是我的代码。
<?php
$target = 'image_uploads/';
if(isset($_FILES['image_name'])===true){
$files = $_FILES['image_name'];
for($x = 0 ; $x < count($files['name']); $x++){
$name = $files['name'][$x] ;
$temp_name = $files['tmp_name'][$x];
#extention filter it takes only the extension want
$allowed ='gif,png,jpg,pdf';
$extension_allowed= explode(',',$allowed );
$file_extention = pathinfo($name, PATHINFO_EXTENSION);
if(array_search($file_extention,$extension_allowed)){
}else {
echo 'We only allow gif, png ,jpg';
exit();
} #extention filter ends here
#check the size of the image
$file_size = $files['size'][$x];
if($file_size > 2097152){
echo 'The file should be lesS than 2MB';
exit();
}
#check the size of the image ends here
#Rename images
$sub = substr(md5(rand()),0,7);
#the above generates char and numbesr
$rand = rand(0,100000);
$rename = $rand.$sub.$name;
#Rename images ends here
$move = move_uploaded_file($temp_name,$target.$rename);
#code to deal with the picture uploads ends here
}}
?>
