    Hello,

    I’m experiencing the following problem: all the galleries are currently capped to 158 pictures. Screenshots
    I haven’t had a chance to debug your plugin, but I after reading just few lines of code I can suppose that the problem is with serialize(base64_encode(...)) and unserialize(base64_decode(...)) calls. On of these two functions or both of them might have a maximum length limit. If I won’t get any reply from you I will try to dig into this problem and try to fix it by my self.. and later will create a PR on GitHub, but I hope you will fix it before I get there ??

    Hi Salaros,

    The problem you are talking about is related to server configuration. There is limit of data posting on your server.

    The variable post_max_size is responsible for this. You need to increase size of that variable using server php.ini file

    Here the thread via you can increase the size of data posting variable – https://stackoverflow.com/questions/6135427/increasing-the-maximum-post-size

    OR

    You can contact to your hosting provider to update this for you.

    Plugin has no bug regarding adding unlimited images, you can test plugin on local server where you found post_max_size is 20M.
    So, you can add more than 250+ images easily in single gallery local server. If you increase size of post variable then adding images limit also increase.

    Thanks

    Currently I have post_max_size, upload_max_filesize set to 30M + some other params such as max_execution_time in order to upload big images on slow connections.
    I will test it on a local server, but I don’t get why post_max_size should influence the serialized image info.
    I mean once I’ve uploaded the images into the native WordPress Media, I just have to create a set of those images and post their names/paths + some additional pieces of data to the script which persists them as post meta inside the DB.
    These serialized meta values are just few KBs, so IMHO there is no need for “big” values of post_max_size

    I have just tested post_max_size set to 40M, the result is still the same – max 158 images. I’ve inserted a phpinfo();die; into the function which persists the $_POST content (BTW it’s few KBs of text, just like I said before).

    I my case $TotalImages = count($_POST['wrgf_image_url']); is always = 158

    OK, I got rid of the limit. It was actually a php.ini entry, but one called max_input_vars. I suppose that by raising its value you allow PHP to post longer input variables (arrays), in your case wrgf_image_url[], wrgf_image_url2[], ..
    Thanks for pointing out possible php.ini config issue.

    Salaros, Great to hear that and you found the exact thing max_input_vars.

    Thanks for all your efforts.
