Getting: Allowed memory size of 33554432 bytes exhausted
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 12288 bytes).
Thats the error i get when i try to upload a image on around 2,94 mb.
When i upload a image on 100kb and so it works fine. Why is this?
How can i make a restriction, so if you upload over xx bytes then you will get error that its too big, so i dont get that fatal error.
i started doing this at the form
$max_file_size = 8388608;
<input type="hidden" name="MAX_FILE_SIZE" value="<?php echo $max_file_size ?>">
Here's my file upload:
<?php

// possible PHP upload errors
$errors = array(1 => 'php.ini max file size exceeded',
2 => 'html form max file size exceeded',

It sounds like it's the overall memory_limit, not the upload limit. Are you processing the image once uploaded with GD?
If so, this will be much more memory intensive on larger images if you're doing a lot of post processing on the uploads - in this case try upping the memory limit, if you're doing something much more straight forward then there is probably another cause for the large memory usage...
very simple
Create a file called "php.ini" in the "wp-admin" folder of wordpress install.
Add the following text to the file:
memory_limit = 256M ;
加载中,请稍侯......
