本文实例讲述了php上传文件并显示上传进度的方法。分享给大家供大家参考。具体如下:
记得上传文件的时候要大点,不然还没看出来就上传完了,并且上传的文件不要太大,上G的就算了,2G的我试了,PHP受不了,我测试的是300多M的,记得要调整小php.ini参数啊 “选文件=》提交=》获取信息”要一气呵成哦^ ^

<?php $prefix = ini_get ( 'session.upload_progress.prefix' ); $name = ini_get ( 'session.upload_progress.name' ); $key = $prefix . $name ; session_start(); if (isset( $_POST [ 'get_info' ])) { $logo = $prefix . $_POST [ 'logo' ]; exit (json_encode( $_SESSION [ $logo ])); } elseif ( $_POST ) { echo '<script>var finashed = true;</script>' ; } ?> <div id= "show_info_div" ></div> <form action= "index.php" method= "POST" enctype= "multipart/form-data" > <input type= "hidden" name= "<?php echo $name; ?>" value= "test" > <input type= "file" name= "file" ><br> <input type= "submit" value= "提交" > <input type= "button" value= "获取信息" onclick= "getUploadInfo()" > </form> <script src= "jquery.js" ></script> <script> var sto = null; var progress = null; function getUploadInfo() { $.post( "index.php" , { "get_info" : 1, "logo" : "test" }, function (data) { data = eval ( "(" + data + ")" ); progress = parseInt(parseInt(data.bytes_processed) * 10000 / parseInt(data.content_length)) / 100 + "%" ; document.getElementById( "show_info_div" ).innerHTML = progress; sto = setTimeout( "getUploadInfo()" , 1000); }); } if (typeof(finashed) !== "undefined" ) { document.getElementById( "show_info_div" ).innerHTML = "100.00% (上传成功!)" ; } </script> |
