我想通过网址只需点击一下即可上传1000张图片。我有1000个图像URL存储在MYSQL数据库中。
所以请任何人给我PHP代码,通过mysql数据库通过URL上传1000张图片。
目前我正在使用以下代码: - 它通过发布图像的URL ...每次点击上传一个图像。
但我希望通过从数据库
获取网址,一键上传1000张图片$result = mysql_query("SELECT * FROM thumb") or die(mysql_error());
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $result )) {
echo "<div>";
$oid = $row['tid'];
$th= $row['q'];
echo "</div>";
$thi = $th;
$get_url = $post["url"];
$url = trim('$get_url');
if($url){
$file = fopen($url,"rb");
$directory = "thumbnail/";
$valid_exts = array("php","jpeg","gif","png","doc","docx","jpg","html","asp","xml","JPEG","bmp");
$ext = end(explode(".",strtolower(basename($url))));
if(in_array($ext,$valid_exts)){
$filename = "$oid.$ext";
$newfile = fopen($directory . $filename, "wb");
if($newfile){
while(!feof($file)){
fwrite($newfile,fread($file,1024 * 8),1024 * 8);
}
echo 'File uploaded successfully';
echo '**$$**'.$filename;
}
else{
echo 'File does not exists';
}
}
else{
echo 'Invalid URL';
}
}
else{
echo 'Please enter the URL';
}
}
非常感谢.... ...

您拥有的代码已经过时,而且比您需要的代码更复杂。这不是一个你获得代码的网站,因为你问,这是一个学习环境。
我将举例说明你可以继续:
// Select the images (those we haven't done yet):
$sItems = mysql_query("SELECT id,url FROM thumb WHERE imported=0") or die(mysql_error());
// Loop through them:
while( $fItems = mysql_fetch_assoc($sItems) ){
$imgSource = file_get_contents($fItems['url']); // get the image
// Check if it didn't go wrong:
if( $imgSource!==false ){
// Which directory to put the file in:
$newLocation = $_SERVER['DOCUMENT_ROOT']."/Location/to/dir/";
// The name of the file:
$newFilename = basename($fItems['url'], $imgSource);
// Save on your server:
file_put_content($newLocation.$newFilename);
}
// Update the row in the DB. If something goes wrong, you don't have to do all of them again:
mysql_query("UPDATE thumb SET imported=1 WHERE id=".$fItems['id']." LIMIT 1") or die(mysql_error());
}
相关功能:
file_get_contents() - 获取图片的内容
file_put_contents() - 将此函数中给出的内容放在指定的文件中
basename() - 给定一个网址,它只为您提供文件名
重要提示:
