我的uploadify 脚本适用于包括IE 在内的所有浏览器。但不能在Firefox中工作。我有三个文件。1>包含uploadify脚本和变量2>是newuploadify.php，它启动会话并给会话变量一些值。3>是基于会话在数据库中插入数据。

这在除 chromium（不是 Chrome）和 Firefox 之外的所有浏览器中都能很好地工作。

不知何故，会话没有从第二个文件传递到 Firefox 中的第三个文件。

我的脚本

session_start();

        },

               $j("#photouploadstartbtn").hide();

               changeBtnText();
    }


    }); /* closing uploadify line*/

}); /* closing funciton line*/
}); /*closing document ready function*/
function changeBtnText() {
    $j('#file_upload').uploadify('settings','buttonText','Change Photo');
}
function restoreBtnText() {
    $j('#file_upload').uploadify('settings','buttonText','Add Photo');
}   

</script>
</head>
<body>
<table>
<tr>
<td id="filein">
<input type="file" name="file_upload" id="file_upload" />
</td>
<td id="btns">
<a id="photouploadstartbtn" href="javascript:$j('#file_upload').uploadify('upload')">Start Upload</a><br>
<a id="photocancelbtn" href="javascript:$j('#file_upload').uploadify('cancel','*');">Remove photo</a>
</td>
</tr>
</table>
</body>

还尝试在上面的代码中通过 scriptData 传递数据，但结果仍然相同。

#Getting if photo is added.

                //$photo=$_SESSION['photo'];#Encoding string as image. For using mysqli no need to do this step.just bind param as string.
                $photopath=$_SESSION['photopath'];

                #Inserting 
                if($photocheck=='Y'){
                error_log('Entered into insert q');

                }
                else{
                error_log('Did not enter !!');
                }

我在使用 firefox 时没有输入，在使用其他浏览器时输入了 insert q。请帮我 。

您不必这样做：

<?php if (!isset($_SESSION)) {
         session_start();
      }
?>

PHP 知道不要开始另一个会话，所以你可以让它保持原样

<?php
     session_start();
?>

还要确保你没有任何输出，require('connection.php');如果它只是PHP你可以省略最后?>一个 php 块的脚本，只是为了确保你没有任何额外的空间。

    session_destroy();
    session_id($session_id);
    @session_start();    
}
