Question

我使用此脚本上传.jpg和＆amp ;; .png类型到服务器和数据库但是当涉及到.jpeg或.JPG时它不起作用，而不是将文件放在正确的目录中并且具有正确的扩展名，它只是自动添加/galleri/uploads/a4b7c7fb0de9c561110c2279f24ec820jpeg.php。 php结束了。

我一直试图做的是添加这些行

if ( $type == 'image/jpeg' ) { $filetype = '.jpeg'; } else {  $filetype = str_replace( 'image/', '', $type ); }

if ( $type == 'image/jpeg' ) { $filetype = '.JPG'; } else {  $filetype = str_replace( 'image/', '', $type ); }

但没有用..

除此之外，还有更好的裁剪工具，我可以在这种情况下使用这种工具吗？

这是完整的脚本：

if(isset($_POST['addmedia'])) {
    $mediatype =    escape(striptags($_POST['mediatype']));
    $title =        escape(striptags($_POST['title']));
    $video =        escape(striptags($_POST['medialink']));
    $date =         date('Y-m-d');

    if ($mediatype === 'img') {
        if( !isset( $_POST['p'] ) ) { $_POST['p']= 0; }

        if( $_POST['p'] == 1 ) {
            $name =     $_FILES['image']['name'];
            $temp =     $_FILES['image']['tmp_name'];
            $type =     $_FILES['image']['type'];
            $size =     $_FILES['image']['size'];

            if ( $type == 'image/jpeg' ) { $filetype = '.jpg'; } else {  $filetype = str_replace( 'image/', '', $type ); }
            if ( $type == 'image/png' ) { $filetype = '.png'; } else {  $filetype = str_replace( 'image/', '', $type ); }

            $path =             md5( rand(0, 1000) . rand(0, 1000) . rand(0, 1000) . rand(0, 1000) ) . $filetype;
            $thumb_path =       md5( rand(0, 1000) . rand(0, 1000) . rand(0, 1000) . rand(0, 1000) ) . $filetype;

            $size2  =   getimagesize ($temp);
            $width  =   $size2[0];
            $height =   $size2[1];

            $maxwidth   =   1281;
            $maxheight  =   751;
            $allowed    =   array('image/jpeg', 'image/png');

            if( in_array( $type, $allowed ) ) {
                if( $width < $maxwidth && $height < $maxheight) {
                    if( $size < 10485760) {
                        if( $width == $height ) { $case = 1;}   // Square form
                        if( $width > $height ) { $case = 2;}    // Lying form
                        if( $width < $height ) { $case = 3;}    // Standing form

                        switch($case) {
                            case 1:
                            $newwidth   =    280;
                            $newheight  =    150;
                            break;

                            case 2:
                            $newheight  =   150;
                            $ratio      =   $newheight / $height;
                            $newwidth   =   round($width * $ratio);
                            break;

                            case 3:
                            $newwidth   =   280;
                            $ratio      =   $newwidth / $width;
                            $newheight  =   round($height * $ratio);

试试这个：

<?php

    ...

    $name = $_FILES['image']['name'];
    $temp = $_FILES['image']['tmp_name'];
    $size = $_FILES['image']['size'];

    $type = image_type_to_mime_type(exif_imagetype($temp)); // get the real image mime type

    if ( $type == 'image/jpeg' ) { // jpeg

        $filetype = '.jpg'; 

    } else if ( $type == 'image/png' ){ // png

        $filetype = '.png';

    } else { // other image type

        $filetype = '.' . str_replace( 'image/', '', $type ); // to get .gif for a gif image, for example

    }

    ...

?>

当.jpeg是类型时，将图像上传到服务器不起作用
