In wordpress, if you see an error message when you trying to upload a file that even though you set the upload_max_filesize to the right size, it still say exceeding the limit. That’s because post_max_size needs to be set accordinly (it has to be biggr than upload_max_filesize).
There are 2 setting key controls file upload.
upload_max_filesize and post_max_size
post_max_size has to be bigger than upload_max_filesize, because post_max_size specifies the limit of the post data (in upload, besides the file size limit, it would also include misc information in upload).
For example:
upload_max_filesize = 25M
post_max_size = 30M
Howto optimize your PHP installation to handle large file uploads.
Though PHP presents a very versatile and user friendly interface for handling file uploads, the default installation is not geared for working with files in excess of 2 Mega Bytes. This article will help you configure your PHP engine for handling such large file transfers.
The php.ini FileAll the configuration settings for your installation are contained in the php.ini file. Sometimes these setting might be overridden by directives in apache .htaccess files or even with in the scripts themselves. However you cannot over ride some of the settings that effect file uploads with .htaccess directives in this way. So let’s just concentrate on the ini file.
You can call the phpinfo() function to find the location of your php.ini file, it will also tell you the current values for the following settings that we need to modify
• file_uploads
• upload_max_filesize
• max_input_time
• memory_limit
• max_execution_time
• post_max_sizeThe first one is fairly obvious if you set this off, uploading is disabled for your installation. We will cover the rest of the configuration settings in detail below.
upload_max_filesize and post_max_size
Files are usually POSTed to the webserver in a format known as ‘multipart/form-data’. The post_max_size sets the upper limit on the amount of data that a script can accept in this manner. Ideally this value should be larger than the value that you set for upload_max_filesize.
It’s important to realize that upload_max_filesize is the sum of the sizes of all the files that you are uploading. post_max_size is the upload_max_filesize plus the sum of the lengths of all the other fields in the form plus any mime headers that the encoder might include. Since these fields are typically small you can often approximate the upload max size to the post max size.
According to the PHP documentation you can set a MAX_UPLOAD_LIMIT in your HTML form to suggest a limit to the browser.
memory_limit
When the PHP engine is handling an incoming POST it needs to keep some of the incoming data in memory. This directive has any effect only if you have used the –enable-memory-limit option at configuration time. Setting too high a value can be very dangerous because if several uploads are being handled concurrently all available memory will be used up and other unrelated scripts that consume a lot of memory might effect the whole server as well.max_execution_time and max_input_time
These settings define the maximum life time of the script and the time that the script should spend in accepting input. If several mega bytes of data are being transfered max_input_time should be reasonably high. You can override the setting in the ini file for max_input_time by calling the set_time_limit() function in your scripts.
