我是PHP新手。
我编译了下面的PHP代码，将图像重新调整为两个大小，效果很好。
我的问题
我需要将上传的图像路径保存在MySQL数据库中。
路径
1） 小图像的路径
2） 大图像的路径
这是代码
<?php
error_reporting(0);
$change="";
$abc="";
define ("MAX_SIZE","400");
function getExtension($str) {
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
$errors=0;
if($_SERVER["REQUEST_METHOD"] == "POST")
{
$image =$_FILES["file"]["name"];
$uploadedfile = $_FILES['file']['tmp_name'];
if ($image)
{
$filename = stripslashes($_FILES['file']['name']);
$extension = getExtension($filename);
$extension = strtolower($extension);
if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif"))
{
$change='<div class="msgdiv">Unknown Image extension </div> ';
$errors=1;
}
else
{
$size=filesize($_FILES['file']['tmp_name']);
if ($size > MAX_SIZE*1024)
{
$change='<div class="msgdiv">You have exceeded the size limit!</div> ';
$errors=1;
}
if($extension=="jpg" || $extension=="jpeg" )
{
$uploadedfile = $_FILES['file']['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);
}
else if($extension=="png")
{
$uploadedfile = $_FILES['file']['tmp_name'];
$src = imagecreatefrompng($uploadedfile);
}
else
{
$src = imagecreatefromgif($uploadedfile);
}
echo $scr;
list($width,$height)=getimagesize($uploadedfile);
$newwidth=150;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);
$newwidth1=50;
$newheight1=($height/$width)*$newwidth1;
$tmp1=imagecreatetruecolor($newwidth1,$newheight1);
imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
imagecopyresampled($tmp1,$src,0,0,0,0,$newwidth1,$newheight1,$width,$height);
$filename = "profile.pic/profile/big" .date('Y-m-d_His - '). $_FILES['file']['name'];
$filename1 = "profile.pic/header/small".date('Y-m-d_His - '). $_FILES['file']['name'];
imagejpeg($tmp,$filename,100);
imagejpeg($tmp1,$filename1,100);
imagedestroy($src);
imagedestroy($tmp);
imagedestroy($tmp1);
}}
}
//If no errors registred, print the success message
if(isset($_POST['Submit']) && !$errors)
{
// mysql_query("update {$prefix}users set img='$big',img_small='$small' where user_id='$user'");
$change=' <div class="msgdiv">Image Uploaded Successfully!</div>';
}
?>
这是表单

任何帮助都将不胜感激。
您应该为这两个图像尝试move_uploaded_file函数。在服务器中创建两个sepearte目录，并循环浏览这两个文件并使用move_uploaded_file。
还要在数据库中创建两个字段来存储这两个路径。并在其中转储两个部分。
$path='pload/'$_FILES[文件']['名称']
move_uploaded_file（$_FILES['file']['tmp_name']，$path）
mysql_query（"插入tablename（文件路径）值（'$path'）"）；
问题：我需要将上传的图像路径保存在MySQL数据库中
您已经有了目录，所以我认为需要为此编写一个数据库查询。
$yourDir = "path to your directory";
$completePathtoYourFile = $yourDir . "/" . $imageName . ".jpg"; //do not append .jpg if already.
了解如何连接到mysql数据库。数据库连接
$insert = "INSERT INTO table_name (field1, field2) VALUES ('$completePathtoYourFile', .......) ";
$result = mysqli_query($connectionVariable, $insert);
if(!$result){
echo "Not Inserted..";
}
else{
echo "Saved..";
}
正如其他人所提到的，您需要将上传的文件从临时存储移动到一个目录，该目录的路径是您的$yourDir。
