PHP：Joomla：-“ iPhone设备”中的文件上传问题（从不同的文件上传字段上传相同的图像），而在桌面上正常

Question

I am facing an issue on all iPhone devices (iphone 4, 5, 6 & iPad). I have created a page:

http://joomla.iworklab.com/aquadam_newtheme/index.php/rfq-construction-stage/constructionstageform

On this page, there many file upload fields but only three file upload fields are taken the same image on iphone devices & others file uploads fields are working fine. File upload fields, those taken same image are given below:

    <input type="file" name="jform[select_picture1_bt]" id="select_picture1_bt" accept="image/png,image/jpeg,image/gif,image/bmp,application/pdf,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document"
aria-invalid="false">

<input type="file" name="jform[select_picture2_bt]" id="select_picture2_bt" accept="image/png,image/jpeg,image/gif,image/bmp,application/pdf,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document">

<input type="file" name="jform[select_picture3_bt]" id="select_picture3_bt" accept="image/png,image/jpeg,image/gif,image/bmp,application/pdf,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document">

Only these three fields are uploading the same image on server while remaining fields are working fine.

I have attached the snapshot of fields those are creating same image issue in iphone devices as given below:

& snapshot of remaining fields on same page, those are working fine on all devices (including iphone) as given below:

Please suggest anyone, how can I fixed this issue?

Thanks in advance :)

Answer 1

I have got the exact cause of this issue:

"In iphone, all the file upload inputs will automatically set with image name 'image.jpg' so when you uploading image in same destination folder then it will pointed to same image."

Hence final solution for it, is either you use unique time stamp with image name at the end of image upload (like: md5(microtime(true)), or md5(rand(true))) or use different destination name for each image.
