PHP多圖上傳取值問題

搞了一個多圖上傳，INPUT裡指定了3個上傳圖片功能，自已搞了一下，發現上傳成功了，圖1能自動改名，圖2和3不能自動改名，請問要怎樣改？

$uploaddir = "uploadfiles/";//設定檔案儲存目錄 注意包含/ $type=array("jpg","gif","bmp","jpeg","png");//設定允許上傳檔案的類型 $patch="uploadfiles/";//程式所在路徑 //擷取檔案尾碼名函數 function fileext($filename) { return substr(strrchr($filename, '.'), 1); } //擷取檔案尾碼名函數 function fileext2($filename2) { return substr(strrchr($filename2, '.'), 1); } //擷取檔案尾碼名函數 function fileext3($filename3) { return substr(strrchr($filename3, '.'), 1); } //產生隨機檔案名稱函數 function random($length) { $hash = 'java-'; $chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz'; $max = strlen($chars) - 1; mt_srand((double)microtime() * 1000000); for($i = 0; $i < $length; $i++) { $hash .= $chars[mt_rand(0, $max)]; } return $hash; } $a=strtolower(fileext($_FILES['img1']['name'])); $b=strtolower(fileext2($_FILES['img2']['name'])); $c=strtolower(fileext3($_FILES['img3']['name'])); //判斷檔案類型 if(!in_array(strtolower(fileext($_FILES['img1']['name'])),$type)) { $text=implode(",",$type); echo "您只能上傳以下類型檔案: ",$text,"
"; } //產生目標檔案的檔案名稱 else{ $filename=explode(".",$_FILES['img1']['name']); $filename2=explode(".",$_FILES['img2']['name']);$filename3=explode(".",$_FILES['img3']['name']);do { $filename[0]=random(10); //設定隨機數長度 $name=implode(".",$filename); //$name1=$name.".Mcncc"; $uploadfile=$uploaddir.$name; $filename[1]=random(10); //設定隨機數長度 $name2=implode(".",$filename2); //$name1=$name.".Mcncc"; $uploadfile2=$uploaddir.$name2; $filename[2]=random(10); //設定隨機數長度 $name3=implode(".",$filename3); //$name1=$name.".Mcncc"; $uploadfile3=$uploaddir.$name3; } while(file_exists($uploadfile)); if (move_uploaded_file($_FILES['img1']['tmp_name'],$uploadfile)){ //if(is_uploaded_file($_FILES['file']['tmp_name'])){ //輸出圖片預覽 //echo "您的檔案已經上傳完畢 上傳圖片預覽: 
"; //echo"
繼續上傳"; //} //else{ //echo "上傳失敗！"; } if (move_uploaded_file($_FILES['img2']['tmp_name'],$uploadfile2)){ //if(is_uploaded_file($_FILES['file']['tmp_name'])){ //輸出圖片預覽 //echo "您的檔案已經上傳完畢 上傳圖片預覽: 
"; //echo"
繼續上傳"; //} //else{ //echo "上傳失敗！"; }if (move_uploaded_file($_FILES['img3']['tmp_name'],$uploadfile3)){ //if(is_uploaded_file($_FILES['file']['tmp_name'])){ //輸出圖片預覽 //echo "您的檔案已經上傳完畢 上傳圖片預覽: 
"; //echo"
繼續上傳"; //} //else{ //echo "上傳失敗！"; }} $SourceFileName=$uploadfile;$SourceFileName2=$uploadfile2;$SourceFileName3=$uploadfile3;

回複討論(解決方案)

??有??， 不??是$filename[0],$filename[1],$filename[2]；而??是$filename[0],$filename2[0],$filename3[0]

do { $filename[0]=random(10); //設定隨機數長度 $name=implode(".",$filename); //$name1=$name.".Mcncc"; $uploadfile=$uploaddir.$name; $filename[1]=random(10); //設定隨機數長度 $name2=implode(".",$filename2); //$name1=$name.".Mcncc"; $uploadfile2=$uploaddir.$name2; $filename[2]=random(10); //設定隨機數長度 $name3=implode(".",$filename3); //$name1=$name.".Mcncc"; $uploadfile3=$uploaddir.$name3; }

改好後的程式

";}//產生目標檔案的檔案名稱else {    $filename = explode(".", $_FILES['img1']['name']);    $filename2 = explode(".", $_FILES['img2']['name']);    $filename3 = explode(".", $_FILES['img3']['name']);    do {        $filename[0] = random(10); //設定隨機數長度        $name = implode(".", $filename);        //$name1=$name.".Mcncc";        $uploadfile = $uploaddir . $name;        $filename2[0] = random(10); //設定隨機數長度        $name2 = implode(".", $filename2);        //$name1=$name.".Mcncc";        $uploadfile2 = $uploaddir . $name2;        $filename3[0] = random(10); //設定隨機數長度        $name3 = implode(".", $filename3);        //$name1=$name.".Mcncc";        $uploadfile3 = $uploaddir . $name3;    } while (file_exists($uploadfile));    if (move_uploaded_file($_FILES['img1']['tmp_name'], $uploadfile)) {        //if(is_uploaded_file($_FILES['file']['tmp_name'])){        //輸出圖片預覽        //echo "您的檔案已經上傳完畢 上傳圖片預覽: 
";        //echo"
繼續上傳";        //}        //else{        //echo "上傳失敗！";            }    if (move_uploaded_file($_FILES['img2']['tmp_name'], $uploadfile2)) {        //if(is_uploaded_file($_FILES['file']['tmp_name'])){        //輸出圖片預覽        //echo "您的檔案已經上傳完畢 上傳圖片預覽: 
";        //echo"
繼續上傳";        //}        //else{        //echo "上傳失敗！";            }    if (move_uploaded_file($_FILES['img3']['tmp_name'], $uploadfile3)) {        //if(is_uploaded_file($_FILES['file']['tmp_name'])){        //輸出圖片預覽        //echo "您的檔案已經上傳完畢 上傳圖片預覽: 
";        //echo"
繼續上傳";        //}        //else{        //echo "上傳失敗！";            }}$SourceFileName = $uploadfile;$SourceFileName2 = $uploadfile2;$SourceFileName3 = $uploadfile3;?>            

原來那裡設錯了，謝謝了！
